- ------------------------------------------------------------------------------------------------------------------------------------
Risks               The prices of interest-bearing securities are, generally, inversely affected by changes in interest rates and,
                    therefore, are subject to the risk of market price fluctuations. The values of fixed-income securities also may
                    be affected by changes in the credit rating or financial condition of the issuing entities. Mortgage-backed
                    securities are subject to prepayments or refinancings of the mortgage pools underlying such securities which may
                    have an impact upon the yield and the net asset value of the Fund's shares. Certain of the mortgage-backed
                    securities in which the Fund may invest have higher yields than traditional mortgage-backed securities and will
                    have concomitant greater price volatility. Asset-backed securities involve risks resulting mainly from the fact
                    that such securities do not usually contain the complete benefit of a security interest in the related
                    collateral. Certain of 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 the higher rated lower yielding fixed-income
                    securities. The foreign securities and markets in which the Fund will invest pose different and generally
                    greater risks than those risks customarily associated with domestic securities and markets including
                    fluctuations in foreign currency exchange rates, foreign tax rates and foreign exchange controls. (see page 7).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean  Witter  Short-Term  Bond  Fund (the  "Fund")  is  a  no-load, 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 October 22, 1993.
 
    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-seven investment companies, thirty of  which
are listed on the New York Stock Exchange, with combined assets of approximately
$81.8 billion at May 31, 1996. The Investment Manager also manages portfolios of
pension plans, other institutions and individuals which aggregated approximately
$2.8 billion at such date.
    
 
    The  Fund has  retained the  Investment Manager,  pursuant to  an Investment
Management Agreement, 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 to the Fund.
 
    The  Fund's Board of  Trustees reviews the various  services provided by the
Investment Manager to  ensure that  the Fund's general  investment policies  and
programs  are being  properly carried out  and that  administrative services are
being provided to the Fund in a satisfactory manner.
 
   
    As full compensation for the services  and facilities furnished to the  Fund
and  for expenses of the  Fund assumed by the  Investment Manager, the Fund pays
the Investment Manager  monthly compensation  calculated daily  by applying  the
following  annual rate of  0.70% to the  Fund's net assets  determined as of the
close of each business day. The Investment Manager had undertaken to assume  all
operating  expenses (except for  any brokerage fees)  and waive the compensation
provided for in its Investment Management Agreement until such time as the  Fund
has  $50 million of  net assets or  until December 31,  1995, whichever occurred
first. The  Investment  Manager has  undertaken  from January  1,  1996  through
December  31, 1996 to continue to assume  all operating expenses (except for any
brokerage fees)  and  to continue  to  waive  compensation to  the  extent  such
expenses and compensation exceed on an annualized basis 1.0% of the Fund's daily
net  assets. For the  fiscal year ended  April 30, 1996,  the Fund accrued total
compensation to the Investment Manager of 0.16% of the Fund's average daily  net
assets  and the Fund's total  expenses accredited to an  annual rate of 0.37% of
the Fund's average daily net assets exclusive of any waivers.
    
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The investment objective  of the Fund  is to provide  investors with a  high
level  of  current income,  consistent with  the  preservation of  capital. This
investment objective is a fundamental policy of  the Fund and, as such, may  not
be  altered without the  approval of the  shareholders of the  Fund. There is no
assurance that the Fund will achieve its investment objective.
 
    The  Fund  seeks  to  achieve  its  investment  objective  by  investing  in
short-term,  fixed-income  securities with  a dollar-weighted  average portfolio
maturity of less than three years. The Fund may invest in nominally  longer-term
securities  that  have many  of the  characteristics of  shorter-term securities
which will be  deemed to have  maturities earlier than  their ultimate  maturity
dates (E.G., securities
 
                                       5
<PAGE>
with  demand  features).  A substantial  portion  of the  Fund's  portfolio will
consist of fixed-income securities issued by  U.S. corporate issuers and by  the
U.S. Government, its agencies and instrumentalities.
 
    Under normal market conditions, at least 65% of the Fund's total assets will
be invested in bonds (for purposes of this provision, debt securities, which had
at  time  of  issuance a  maturity  of greater  than  one year,  are  defined as
"bonds"). Furthermore,  a portion  of the  Fund's portfolio  (up to  25% of  the
Fund's  total  assets)  may be  invested  in fixed-income  securities  issued by
foreign corporate and government issuers.
 
    The Fund is designed for the investor who seeks a higher yield than a  money
market  fund and  less fluctuation  in net asset  value than  a longer-term bond
fund. In addition, while an investment in the Fund is not federally insured  and
there  is no guarantee of  price stability (the Fund is  not a money market fund
with a virtually constant net asset value per share), an investment in the  Fund
- --  unlike a  certificate of deposit  ("CD") --  is not frozen  for any specific
period of time, may be redeemed  at any time without incurring early  withdrawal
penalties, and may also provide a higher yield.
 
    The  non-governmental debt  securities in  which the  Fund will  invest will
include: (a) corporate  debt securities, including  bonds, notes and  commercial
paper,  rated  in  the  four  highest  categories  by  a  nationally  recognized
statistical rating organization ("NRSRO")  including Moody's Investors  Service,
Inc.,  Standard & Poor's Corporation, Duff  and Phelps, Inc. and Fitch Investors
Service, Inc.; (b)  bank obligations,  including CDs,  banker's acceptances  and
time  deposits, issued by  banks with a long-term  CD rating in  one of the four
highest  categories  by  a  NRSRO;  and  (c)  investment  grade  fixed-rate  and
adjustable  rate  Mortgage-Backed  and Asset-Backed  securities  (see  below) of
corporate issuers.  Investments  in securities  rated  within the  four  highest
rating  categories by a  NRSRO are considered  "investment grade." However, such
securities rated within the fourth highest  rating category by a NRSRO may  have
speculative  characteristics and,  therefore, changes in  economic conditions or
other circumstances are more likely to  weaken their capacity to make  principal
and interest payments than would be the case with investments in securities with
higher credit ratings. Where a fixed-income security is not rated by a NRSRO (as
may  be the  case with a  foreign security)  the Investment Manager  will make a
determination of its creditworthiness and may deem it to be investment grade.
 
    The Fund  may also  invest in  preferred stocks  rated in  one of  the  four
highest categories by a NRSRO.
 
    Up to 5% of the Fund's net assets may be invested in fixed-income securities
rated  below investment grade. Such lower-rated  securities are considered to be
speculative investments and, while producing higher yields than investment grade
securities, are subject  to greater  credit risks. The  Fund does  not have  any
minimum  quality rating standards with respect to this portion of its portfolio.
If an investment grade fixed-income security held by the Fund is downgraded by a
rating agency  to a  grade below  investment  grade, the  Fund may  retain  such
security  in its  portfolio unless such  downgraded security,  together with all
other non-investment grade fixed-income securities held by the Fund  constitute,
in  the aggregate,  more than 5%  of the Fund's  net assets. In  such event, the
Investment Manager will seek to sell such securities from its portfolio, as soon
as is reasonably  practicable, in  sufficient amounts  to reduce  this total  to
below  5% of its net  assets. A description of  fixed-income security ratings is
contained in the Appendix to the Statement of Additional Information.
 
   
    The United States Government  securities (including zero coupon  securities)
in which the Fund will invest include securities which are direct obligations of
the  United States Government,  such as United States  treasury bills, and which
are backed by the full faith and  credit of the United States; securities  which
are  backed by  the full  faith and credit  of the  United States  but which are
    
obliga-
 
                                       6
<PAGE>
tions of a  United States agency  or instrumentality (E.G.,  obligations of  the
Government  National Mortgage Association); securities issued by a United States
agency  or  instrumentality  which  has  the  right  to  borrow,  to  meet   its
obligations,  from an  existing line of  credit with the  United States Treasury
(E.G., obligations  of the  Federal National  Mortgage Association);  securities
issued  by a  United States  agency or  instrumentality which  is backed  by the
credit of  the  issuing agency  or  instrumentality (E.G.,  obligations  of  the
Federal   Farm  Credit   System);  and   governmentally  issued  mortgage-backed
securities.
 
    In addition, as stated above,  up to 25% of the  Fund's total assets may  be
invested  in securities issued by foreign corporations and governments and their
agencies and instrumentalities.  Such securities may  be denominated in  foreign
currencies.  The principal foreign  currencies in which  such securities will be
denominated are:  the Australian  dollar; Deutsche  mark; Japanese  yen;  French
franc; British pound; Canadian dollar; Mexican peso; Swiss franc; Dutch guilder;
Austrian  schilling; Spanish Peseta; Swedish  Krona; and European Currency Unit.
The Fund will only invest  in foreign securities which are  rated by a NRSRO  as
investment  grade or which, if unrated, are  deemed by the Investment Manager to
be of investment grade creditworthiness.
 
RISKS AND PORTFOLIO CHARACTERISTICS
 
    MORTGAGE-BACKED SECURITIES    As  stated  above, a  portion  of  the  Fund's
investments may be in Mortgage-Backed securities. Mortgage-Backed securities are
securities  that directly  or indirectly  represent a  participation in,  or are
secured by and payable from, mortgage  loans secured by real property. The  term
Mortgage-Backed  securities  as used  herein  includes adjustable  rate mortgage
securities and  derivative mortgage  products  such as  collateralized  mortgage
obligations,  stripped Mortgage-Backed  securities and  other products described
below.
 
    There are currently  three basic  types of  Mortgage-Backed securities:  (i)
those  issued  or guaranteed  by  the United  States  Government or  one  of its
agencies  or  instrumentalities,  such  as  the  Government  National   Mortgage
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC") (securities issued by GNMA, but
not  those issued by FNMA or FHLMC, are backed by the "full faith and credit" of
the United  States); (ii)  those issued  by private  issuers that  represent  an
interest  in  or  are  collateralized by  Mortgage-Backed  securities  issued or
guaranteed  by  the  United  States  Government  or  one  of  its  agencies   or
instrumentalities;  and (iii) those issued by  private issuers that represent an
interest in or  are collateralized  by whole mortgage  loans or  Mortgage-Backed
securities  without  a  government guarantee  but  usually having  some  form of
private credit enhancement (described below).
 
    The Fund  will  invest  in  mortgage  pass-through  securities  representing
participation  interests in  pools of  residential mortgage  loans originated by
United States  governmental or  private lenders  and guaranteed,  to the  extent
provided  in such  securities, by  the United  States Government  or one  of its
agencies or instrumentalities. Such securities, which are ownership interests in
the underlying mortgage loans, differ  from conventional debt securities,  which
provide for periodic payment of interest in fixed amounts (usually semiannually)
and  principal  payments  at  maturity  or  on  specified  call  dates. Mortgage
pass-through securities provide for monthly  payments that are a  "pass-through"
of  the monthly interest and principal payments (including any prepayments) made
by the individual borrowers on the pooled  mortgage loans, net of any fees  paid
to  the guarantor of such securities and the servicer of the underlying mortgage
loans.
 
    The guaranteed mortgage  pass-through securities in  which the Fund  invests
include  those issued or  guaranteed by GNMA, FNMA  and FHLMC. GNMA certificates
are direct obligations of the  U.S. Government and, as  such, are backed by  the
"full  faith and credit"  of the United  States. FNMA is  a federally chartered,
privately owned corporation
 
                                       7
<PAGE>
and FHLMC is a  corporate instrumentality of the  United States. FNMA and  FHLMC
certificates  are not backed by  the full faith and  credit of the United States
but the issuing agency or instrumentality has  the right to borrow, to meet  its
obligations,  from an existing line  of credit with the  U.S. Treasury. The U.S.
Treasury has no legal obligation to provide  such line of credit and may  choose
not to do so.
 
    Certificates  for  Mortgage-Backed  securities  evidence  an  interest  in a
specific pool of  mortgages. These  certificates are, in  most cases,  "modified
pass-through"  instruments, wherein the issuing agency guarantees the payment of
principal and interest on mortgages underlying the certificates, whether or  not
such amounts are collected by the issuer on the underlying mortgages.
 
    Private  mortgage pass-through  securities are  structured similarly  to the
GNMA, FNMA  and  FHLMC  mortgage  pass-through  securities  and  are  issued  by
originators  of  and investors  in mortgage  loans,  including savings  and loan
associations, mortgage  banks, commercial  banks, investment  banks and  special
purpose  subsidiaries of the foregoing. These securities usually are backed by a
pool of conventional fixed rate or adjustable rate mortgage loans. Since private
mortgage pass-through  securities  typically are  not  guaranteed by  an  entity
having  the credit status of GNMA, FNMA and FHLMC, such securities generally are
structured with one or more types of credit enhancement.
 
    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,  twenty-four,  thirty-six  or  longer
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.
 
    COLLATERALIZED MORTGAGE OBLIGATIONS.  The Fund may invest in  collateralized
mortgage  obligations  or "CMOs".  CMOs are  debt obligations  collateralized by
mortgage  loans  or  mortgage  pass-through  securities.  Typically,  CMOs   are
collateralized   by  GNMA,  FNMA,  or  FHLMC   certificates,  but  also  may  be
collateralized by whole loans or private mortgage pass-through securities  (such
collateral  is  collectively  hereinafter  referred  to  as  "Mortgage Assets").
Multiclass pass-through securities are equity  interests in a trust composed  of
Mortgage  Assets. Payments of principal of  and interest on the Mortgage Assets,
and any reinvestment income  thereon, provide the funds  to pay debt service  on
the  CMOs  or  make  scheduled  distributions  on  the  multiclass  pass-through
securities. CMOs may be  issued by agencies or  instrumentalities of the  United
States  Government,  or by  private originators  of,  or investors  in, mortgage
loans, including  savings  and  loan associations,  mortgage  banks,  commercial
banks, investment banks and special purpose subsidiaries of the foregoing.
 
    The  issuer of a  series of CMOs  may elect to  be treated as  a Real Estate
Mortgage Investment  Conduit  ("REMIC").  REMICs include  governmental  and/  or
private entities that issue a fixed pool of
mort-
 
                                       8
<PAGE>
gages  secured by an  interest in real  property. REMICs are  similar to CMOs in
that they  issue multiple  classes of  securities, but  unlike CMOs,  which  are
required  to  be structured  as  debt securities,  REMICs  may be  structured as
indirect ownership interests in the underlying assets of the REMICs  themselves.
However,  there are  no effects  on the  Fund from  investing in  CMOs issued by
entities that have elected to be treated as REMICs, and all future references to
CMOs shall also be deemed  to include REMICs. In  addition, in reliance upon  an
interpretation  by  the staff  of the  Securities  and Exchange  Commission with
respect to  limitations contained  in Section  12(d) of  the Act,  the Fund  may
invest without limitation in CMOs and other Mortgage-Backed securities which are
not  by  definition excluded  from the  provisions  of the  Act, and  which have
obtained exemptive orders from such provisions from the Securities and  Exchange
Commission.
 
    In  a CMO, a series of bonds  or certificates is issued in multiple classes.
Each class of CMOs, often  referred to as a "tranche",  is issued at a  specific
fixed  or floating coupon rate  and has a stated  maturity or final distribution
date. Principal prepayments  on the  Mortgage Assets may  cause the  CMOs to  be
retired substantially earlier than their stated maturities or final distribution
dates.  Interest is  paid or accrues  on all classes  of the CMOs  on a monthly,
quarterly or  semiannual  basis. Certain  CMOs  may have  variable  or  floating
interest  rates and  others may be  stripped (securities which  provide only the
principal or interest feature of the underlying security).
 
    The principal of and interest on the Mortgage Assets may be allocated  among
the  several classes of a  CMO series in a  number of different ways. Generally,
the purpose of the allocation of the cash  flow of a CMO to the various  classes
is to obtain a more predictable cash flow to the individual tranches than exists
with  the  underlying  collateral  of  the CMO.  As  a  general  rule,  the more
predictable the cash flow is on a  CMO tranche, the lower the anticipated  yield
will  be on that tranche  at the time of  issuance relative to prevailing market
yields on Mortgage-Backed securities.  As part of the  process of creating  more
predictable  cash flows on most of the tranches in a series of CMOs, one or more
tranches generally must  be created that  absorb most of  the volatility in  the
cash  flows on the underlying  mortgage loans. The yields  on these tranches are
generally higher than  prevailing markets yields  on Mortgage-Backed  securities
with  similar maturities. As  a result of  the uncertainty of  the cash flows of
these tranches, the market prices of  and yield on these tranches generally  are
more volatile.
 
    The  Fund may  invest up  to 10%  of its  total assets  in inverse floaters.
Inverse floaters  constitute a  class of  CMOs  with a  coupon rate  that  moves
inversely  to a designated  index, such as the  LIBOR (London Inter-Bank Offered
Rate) Index.  Inverse floaters  have coupon  rates that  typically change  at  a
multiple  of the changes of the relevant index  rate. Any rise in the index rate
(as a consequence of an increase in interest rates) causes a drop in the  coupon
rate  of an inverse floater while any drop  in the index rate causes an increase
in the coupon of an inverse  floater. In addition, like most other  fixed-income
securities,  the  value  of inverse  floaters  will decrease  as  interest rates
increase. Inverse floaters exhibit greater price volatility than the majority of
mortgage pass-through securities  or CMOs.  In addition,  some inverse  floaters
exhibit extreme sensitivity to changes in prepayments. As a result, the yield to
maturity  of an  inverse floater  is sensitive not  only to  changes in interest
rates but also to changes in prepayment rates on the related underlying Mortgage
Assets.
 
    The Fund  also may  invest in,  among other  things, parallel  pay CMOs  and
Planned  Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured
to provide payments of principal  on each payment date  to more than one  class.
These  simultaneous payments  are taken into  account in  calculating the stated
maturity date or final distribution date of each class, which, as with other CMO
structures, must be retired  by its stated maturity  date or final  distribution
date but may be retired
 
                                       9

earlier. PAC Bonds generally require payments of a specified amount of principal
on  each payment date. PAC Bonds always  are parallel pay CMOs with the required
principal payment on such securities having the highest priority after  interest
has been paid to all classes.
 
    STRIPPED MORTGAGE-BACKED SECURITIES. Stripped Mortgage-Backed securities are
derivative  multiclass mortgage securities.  Stripped Mortgage-Backed securities
may be issued by agencies or instrumentalities of the United States  Government,
or by private originators of, or investors in, mortgage loans, including savings
and  loan associations, mortgage  banks, commercial banks,  investment banks and
special purpose subsidiaries of the  foregoing. Up to 15%  of the net assets  of
the Fund may be invested in Stripped Mortgage-Backed Securities.
 
    Stripped  Mortgage-Backed securities usually are structured with two classes
that receive different proportions of the interest and principal distribution on
a pool of Mortgage  Assets. A common type  of Stripped Mortgage-Backed  security
will  have one class  receiving some of  the interest and  most of the principal
from the  Mortgage  Assets, while  the  other class  will  receive most  of  the
interest and the remainder of the principal. In the most extreme case, one class
will  receive all of the  interest (the interest-only or  "IO" class), while the
other class receive all of the principal (the principal-only or "PO" class).  PO
classes generate income through the accretion of the deep discount at which such
securities are purchased, and, while PO classes do not receive periodic payments
of   interest,  they   receive  monthly   payments  associated   with  scheduled
amortization and principal prepayment from the Mortgage Assets underlying the PO
class. The yield to maturity on an  IO class is extremely sensitive to the  rate
of principal payments (including prepayments) on the related underlying Mortgage
Assets,  and a  rapid rate  of principal  payments may  have a  material adverse
effect on  the Fund's  yield  to maturity.  If  the underlying  Mortgage  Assets
experience  greater than anticipated prepayments of principal, the Fund may fail
to fully  recoup  its  initial  investment  in  these  securities  even  if  the
securities are rated investment grade.
 
    The Fund may purchase Stripped Mortgage-Backed securities for income, or for
hedging   purposes  to  protect  the  Fund's  portfolio  against  interest  rate
fluctuations. For example, since an IO class  will tend to increase in value  as
interest  rates rise, it may be utilized to hedge against a decrease in value of
other fixed-income securities in a rising interest rate environment. The  Fund's
management  understands that the staff of the Securities and Exchange Commission
("SEC")  considers   privately   issued  Stripped   Mortgage-Backed   securities
representing  interest only or  principal only components  of U.S. Government or
other debt  securities to  be  illiquid securities.  The  Fund will  treat  such
securities  as illiquid so long as the  staff maintains such position. The staff
of the  SEC  also  takes  the  position that  the  determination  of  whether  a
particular  government-issued IO or PO backed  by fixed-rate mortgages is liquid
may be made under guidelines and  standards established by the Fund's  Trustees.
Such  securities may be deemed liquid if they can be disposed of promptly in the
ordinary course of  business at a  value reasonably  close to that  used in  the
calculation  of the net asset value per share. The Fund may not invest more than
15% of its net assets in illiquid securities.
 
    TYPES OF CREDIT ENHANCEMENT.  Mortgage-Backed securities are often backed by
a pool of assets representing the obligations of a number of different  parties.
To  lessen  the effect  of failures  by  obligors on  underlying assets  to make
payments, those securities may  contain elements of  credit support, which  fall
into two categories: (i) liquidity protection and (ii) protection against losses
resulting  from  ultimate  default  by  an  obligor  on  the  underlying assets.
Liquidity protection  refers to  the  provision of  advances, generally  by  the
entity  administering the pool of assets, to ensure that the receipt of payments
on the underlying  pool occurs in  a timely fashion.  Protection against  losses
resulting   from   default   ensures  ultimate   payment   of   the  obligations
 
                                       10
<PAGE>
on at least a  portion of assets  in the pool. This  protection may be  provided
through  guarantees, insurance  policies or  letters of  credit obtained  by the
issuer or sponsor from third parties,  through various means of structuring  the
transaction  or through a  combination of such approaches.  The degree of credit
support provided for  each issue  is generally based  on historical  information
respecting  the  level of  credit risk  associated  with the  underlying assets.
Delinquencies or losses in  excess of those  anticipated could adversely  affect
the  return  on an  investment  in a  security.  In addition,  any circumstances
adversely affecting the ability of third parties (E.G., insurance companies)  to
satisfy  any of their obligations with  respect to any Mortgage-Backed security,
such as a  diminishment of  their creditworthiness, could  adversely affect  the
value  of  the security.  The Fund  will not  pay any  fees for  credit support,
although the existence of credit support may increase the price of a security.
 
    RISKS  OF  MORTGAGE-BACKED  SECURITIES.    Mortgage-Backed  securities  have
certain  different characteristics  than traditional debt  securities. Among the
major differences  are  that  interest  and principal  payments  are  made  more
frequently,  usually  monthly, and  that principal  may be  prepaid at  any time
because the underlying mortgage loans or  other assets generally may be  prepaid
at  any time. As a result, if the Fund purchases such a security at a premium, a
prepayment rate that  is faster  than expected  will reduce  yield to  maturity,
while  a prepayment  rate that  is slower than  expected will  have the opposite
effect of increasing  yield to  maturity. Alternatively, if  the Fund  purchases
these  securities at a discount, faster than expected prepayments will increase,
while slower than expected prepayments will reduce, yield to maturity. The  Fund
may invest a portion of its assets in derivative Mortgage-Backed securities such
as  Stripped Mortgage-Backed securities which are highly sensitive to changes in
prepayment and  interest rates.  The Investment  Manager seeks  to manage  these
risks  (and potential benefits) by investing in a variety of such securities and
through hedging techniques.
 
    Mortgage-Backed securities,  like  all fixed  income  securities,  generally
decrease  in value  as a  result of  increases in  interest rates.  In addition,
although generally the value of fixed-income securities increases during periods
of falling interest  rates and,  as stated  above, decreases  during periods  of
rising interest rates, as a result of prepayments and other factors, this is not
always the case with respect to Mortgage-Backed securities.
 
    Although  the extent of prepayments  on a pool of  mortgage loans depends on
various economic and other factors, as a general rule prepayments on fixed  rate
mortgage  loans  will increase  during a  period of  falling interest  rates and
decrease  during  a  period  of  rising  interest  rates.  Accordingly,  amounts
available  for reinvestment by the Fund are likely to be greater during a period
of declining interest rates and, as a  result, likely to be reinvested at  lower
interest  rates than during  a period of  rising interest rates. Mortgage-Backed
securities generally decrease  in value  as a  result of  increases in  interest
rates  and may  benefit less than  other fixed-income  securities from declining
interest rates because of the risk of prepayment.
 
    There are certain risks  associated specifically with  CMOs. CMOs issued  by
private  entities are not  U.S. Government securities and  are not guaranteed by
any government agency, although the securities  underlying a CMO may be  subject
to  a guarantee. Therefore, if  the collateral securing the  CMO, as well as any
third party credit support or guarantees,  is insufficient to make payment,  the
holder  could sustain a loss. Also, a number of different factors, including the
extent  of  prepayment  of  principal   of  the  Mortgage  Assets,  affect   the
availability  of cash for  principal payments by  the CMO issuer  on any payment
date and,  accordingly, affect  the timing  of principal  payments on  each  CMO
class. In addition, CMO classes with higher yields tend to be more volatile with
respect  to cash flow of the underlying mortgages; as a result the market prices
of a yield on these classes tend to be more volatile.
 
    ASSET-BACKED SECURITIES.   The Fund may  invest in Asset-Backed  securities.
Asset-Backed
 
                                       11
<PAGE>
securities   represent   the   securitization   techniques   used   to   develop
Mortgage-Backed securities applied to a broad range of other assets. Through the
use of  trusts  and  special  purpose corporations,  various  types  of  assets,
primarily  automobile and  credit card  receivables and  home equity  loans, are
being  securitized   in  pass-through   structures  similar   to  the   mortgage
pass-through structures described above or in a pay-through structure similar to
the CMO structure.
 
    Asset-Backed  securities  involve  certain  risks  that  are  not  posed  by
Mortgage-Backed securities,  resulting mainly  from the  fact that  Asset-Backed
securities do not usually contain the complete benefit of a security interest in
the  related  collateral. For  example,  credit card  receivables  generally are
unsecured and the debtors are  entitled to the protection  of a number of  state
and  federal consumer credit laws, including  the bankruptcy laws, some of which
may reduce  the  ability to  obtain  full payment.  In  the case  of  automobile
receivables, due to various legal and economic factors, proceeds for repossessed
collateral may not always be sufficient to support payments on these securities.
 
    New  instruments and  variations of existing  Mortgage-Backed securities and
Asset-Backed securities continue  to be developed.  The Fund may  invest in  any
such  instruments or  variations as may  be developed, to  the extent consistent
with  its   investment  objective   and  policies   and  applicable   regulatory
requirements.
 
    FOREIGN  SECURITIES.   Foreign  securities  investments may  be  affected by
changes  in  currency  rates  or   exchange  control  regulations,  changes   in
governmental administration or economic or monetary policy (in the United States
and  abroad) or changed circumstances  in dealings between nations. Fluctuations
in the relative rates  of exchange between the  currencies of different  nations
will affect the value of the Fund's investments denominated in foreign currency.
Changes  in foreign  currency exchange  rates relative  to the  U.S. dollar will
affect the U.S. dollar value of  the Fund's assets denominated in that  currency
and thereby impact upon the Fund's total return on such assets.
 
    Foreign  currency  exchange rates  are determined  by  forces of  supply and
demand on the foreign exchange markets. These forces are themselves affected  by
the   international  balance  of  payments  and  other  economic  and  financial
conditions, government intervention,  speculation and  other factors.  Moreover,
foreign currency exchange rates may be affected by the regulatory control of the
exchanges  on which the  currencies trade. The  foreign currency transactions of
the Fund will  be conducted  on a  spot basis  or through  forward contracts  or
futures  contracts (described in  the Statement of  Additional Information). The
Fund will incur certain costs in connection with these currency transactions.
 
    Investments in  foreign  securities will  also  occasion risks  relating  to
political  and  economic  developments  abroad,  including  the  possibility  of
expropriations or confiscatory taxation, limitations  on the use or transfer  of
Fund   assets  and  any  effects  of   foreign  social,  economic  or  political
instability. Foreign companies are not subject to the regulatory requirements of
U.S. companies and, as  such, there may be  less publicly available  information
about  such companies. Moreover,  foreign companies are not  subject to the more
rigorous uniform  accounting, auditing  and  financial reporting  standards  and
requirements applicable to U.S. companies.
 
    Securities  of foreign issuers may be less liquid than comparable securities
of U.S.  issuers  and,  as such,  their  price  changes may  be  more  volatile.
Furthermore,  foreign exchanges and broker-dealers are generally subject to less
government  and   exchange  scrutiny   and   regulation  than   their   American
counterparts.  Brokerage commissions,  dealer concessions  and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of Fund  trades effected in  such markets. Inability  to dispose  of
portfolio  securities due  to settlement  delays could  result in  losses to the
 
                                       12
<PAGE>
Fund due to subsequent declines in value of such securities and the inability of
the Fund to make  intended security purchases due  to settlement problems  could
result in a failure of the Fund to make potentially advantageous investments. To
the  extent  the Fund  purchases Eurodollar  certificates  of deposit  issued by
foreign branches of domestic United States banks, consideration will be given to
their domestic marketability, the  lower reserve requirements normally  mandated
for  overseas banking  operations, the possible  impact of  interruptions in the
flow of international currency transactions, and future international  political
and  economic developments which might adversely affect the payment of principal
or interest.
 
    REPURCHASE AGREEMENTS.  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  ("collateral")  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, the Fund follows procedures designed to minimize
such  risks. These procedures include  effecting repurchase agreements only with
large,  well-capitalized  and  well-established  financial  institutions   whose
financial  condition  will be  continually monitored  by the  Investment Manager
subject to procedures established by the  Trustees of the Fund. In addition,  as
described  above,the value of the collateral underlying the repurchase agreement
will be at least equal to  the repurchase price, including any accrued  interest
earned on the repurchase agreement. In the event of a default or bankruptcy by a
selling  financial institution, the Fund will seek to liquidate such collateral.
However, the exercising of the Fund's  right to liquidate such collateral  could
involve  certain costs or delays and, to  the extent that proceeds from any sale
upon a default  of the obligation  to repurchase were  less than the  repurchase
price, the Fund could suffer a loss.
 
    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. At the time the Fund makes
the commitment to purchase or sell securities on a when-issued, delayed delivery
or  forward  commitment basis,  it will  record  the transaction  and thereafter
reflect the value,  each day,  of such  security purchased  or, if  a sale,  the
proceeds  to be  received in  determining its  net asset  value. At  the time of
delivery of the securities, their value may be more or less than the purchase or
sale price. The Fund will also establish a segregated account with its custodian
bank in which  it will continually  maintain cash or  cash equivalents or  other
high  grade debt portfolio securities equal  in value to commitments to purchase
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 subse-
 
                                       13
<PAGE>
quent  event, such as approval of  a merger, corporate reorganization, leveraged
buyout or  debt restructuring.  The  commitment for  the  purchase of  any  such
security  will  not  be recognized  by  the  Fund until  the  Investment Manager
determines that issuance  of the security  is probable. At  such time, the  Fund
will  record  the transaction  and,  in determining  its  net asset  value, will
reflect the  value of  the security  daily. At  such time,  the Fund  will  also
establish  a  segregated  account  with  its custodian  bank  in  which  it will
continuously maintain cash  or U.S.  Government securities or  other high  grade
debt  portfolio securities  equal in  value to  recognized commitments  for such
securities. Settlement of the trade will occur within five business days of  the
occurrence of the subsequent event. With respect to 75% of its total assets, the
value  of the Fund's commitments  to purchase the securities  of any one issuer,
together with the value of all securities of such issuer owned by the Fund,  may
not  exceed 5% of the value  of the Fund's total assets  at the time the initial
commitment to purchase such securities is made (see "Investment  Restrictions").
Subject  to the foregoing restrictions, the Fund may purchase securities on such
basis without  limit.  An  increase  in the  percentage  of  the  Fund's  assets
committed  to the purchase of securities on a "when, as and if issued" basis may
increase the volatility of its net  asset value. The Investment Manager and  the
Trustees  do not believe that the net asset  value of the Fund will be adversely
affected by its purchase of securities on such basis.
 
    ZERO COUPON  SECURITIES.    A  portion of  the  U.S.  Government  securities
purchased  by the Fund may be "zero  coupon" Treasury securities. These are U.S.
Treasury bills, notes  and bonds  which have  been stripped  of their  unmatured
interest  coupons and receipts or  which are certificates representing interests
in such stripped  debt obligations and  coupons. In addition,  a portion of  the
fixed-income  securities purchased by such Fund may be "zero coupon" securities.
"Zero coupon" securities  are purchased at  a discount from  their face  amount,
giving  the purchaser the right to receive  their full value at maturity. A zero
coupon security pays no interest to its holder during its life. Its value to  an
investor  consists  of the  difference between  its  face value  at the  time of
maturity and the price for which it  was acquired, which is generally an  amount
significantly  less  than  its face  value  (sometimes  referred to  as  a "deep
discount" price).
 
    The  interest  earned  on  such  securities  is,  implicitly,  automatically
compounded  and paid out at maturity. While  such compounding at a constant rate
eliminates the risk of receiving lower  yields upon reinvestment of interest  if
prevailing  interest rates decline, the owner of  a zero coupon security will be
unable to participate in higher yields upon reinvestment of interest received if
prevailing interest  rates rise.  For this  reason, zero  coupon securities  are
subject  to substantially  greater market  price fluctuations  during periods of
changing prevailing interest  rates than  are comparable  debt securities  which
make  current distributions of interest. Current federal tax law requires that a
holder (such as  the Fund) of  a zero coupon  security accrue a  portion of  the
discount at which the security was purchased as income each year even though the
Fund receives no interest payments in cash on the securities during the year.
 
    Currently,  the only  U.S. Treasury security  issued without  coupons is the
Treasury bill. However, in the  last few years a  number of banks and  brokerage
firms  have  separated  ("stripped")  the  principal  portions  from  the coupon
portions of the U.S. Treasury  bonds and notes and  sold them separately in  the
form  of  receipts or  certificates  representing undivided  interests  in these
instruments (which instruments are  generally held by a  bank in a custodial  or
trust account).
 
    Except   as  specifically  noted,  all  investment  policies  and  practices
discussed in this Prospectus  are not fundamental policies  of the Fund and,  as
such, may be changed without shareholder approval.
 
PORTFOLIO MANAGEMENT
 
    The  Fund's portfolio is  managed by its  Investment Manager with  a view to
achieving its
invest-
 
                                       14
<PAGE>
   
ment objective. The Fund is managed  within Taxable Income Group, which  managed
approximately  $13.5  billion in  assets at  May 31,  1996. Rochelle  G. Siegel,
Senior Vice President of InterCapital  and a member of InterCapital's  Corporate
Bond  Group, has  been designated as  the Fund's primary  portfolio manager. Ms.
Siegel has  been managing  portfolios comprised  of fixed-income  securities  at
InterCapital for over five years.
    
 
    Securities  purchased by the Fund are,  generally, sold by dealers acting as
principal for their own accounts. Pursuant to an order issued by the  Securities
and  Exchange Commission, the Fund may  effect principal transactions in certain
money market instruments with Dean Witter Reynolds Inc. ("DWR"), a broker-dealer
affiliate of the Investment Manager. In  addition, the Fund may incur  brokerage
commissions on transactions conducted through DWR.
 
    Although  the  Fund  does not  intend  to engage  in  substantial short-term
trading, it may sell portfolio securities  without regard to the length of  time
that  they  have  been  held,  in order  to  take  advantage  of  new investment
opportunities or yield differentials,  or because the  Fund desires to  preserve
gains or limit losses due to changing economic conditions, interest rate trends,
or  the  financial condition  of the  issuer. The  Fund anticipates  a portfolio
turnover rate of no more than 100%.
 
    INVESTMENT IN OTHER INVESTMENT VEHICLES. Under the Investment Company Act of
1940, as amended (the  "Act"), the Fund  generally may invest up  to 10% of  its
total  assets in the aggregate in shares of other investment companies and up to
3% of its total assets in any one investment company, as long as that investment
company does not  represent more than  5% of  the voting stock  of the  acquired
investment  company at the time such shares are purchased. 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  duplicate  levels  of  fees  with  respect  to  investments  in other
investment companies and in real estate investment trusts.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions  listed below  are among  the restrictions  that
have  been  adopted  by the  Fund  as  fundamental policies.  Under  the  Act, a
fundamental policy may  not be changed  without the  vote of a  majority of  the
outstanding voting securities of the Fund, as defined in the Act.
 
    The Fund may not:
 
   1.  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.  As to 75% of its total assets,  purchase more than 10% of all outstanding
voting securities or any class of securities of any one issuer.
 
   3. Invest 25%  or more  of the  value of its  total assets  in securities  of
issuers  in any  one industry.  This restriction  does not  apply to obligations
issued or  guaranteed  by  the  United States  Government  or  its  agencies  or
instrumentalities.
 
   4.  Invest more  than 5% of  the value of  its total assets  in securities of
issuers having a record, together with predecessors, of less than three years of
continuous operation. This restriction shall not
 
                                       15
<PAGE>
apply to  Mortgage-Backed  securities  or  Asset-Backed  securities  or  to  any
obligation of the United States Government, its agencies or instrumentalities.
 
    If a percentage restriction is adhered to at the time of investment, a later
increase  or  decrease  in  percentage  resulting from  a  change  in  values of
portfolio securities or amount of total or  net assets will not be considered  a
violation of any of the foregoing restrictions.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    The  Fund offers it shares  for sale to the public  on a continuous basis at
the offering price without the imposition of a sales charge. The offering  price
will  be the net asset  value per share next  determined following receipt of an
order (see  "Determination of  Net  Asset Value").  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 are  offered by DWR and other broker-dealers
which  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 Dean  Witter Short-Term Bond
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
other Selected  Broker-Dealers. 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, 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  or  a  Selected
Broker-Dealer 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 or Selected Broker-Dealer. Since DWR or any other  Selected
Broker-Dealer  may forward investors' funds on  settlement date, it 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 dividends  or distributions  if
their  order is received by the close of business on the day prior to the record
date for such dividends and distributions.
 
    Sales personnel of a  Selected Broker-Dealer are  compensated for shares  of
the  Fund sold by them by  the Distributor or any of  its affiliates and/or by a
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 Distributor  is authorized to
utilize its own resources or those of its affiliates, including InterCapital, to
finance certain services and activities  in connection with the distribution  of
the Fund's shares. The principal activities and services
 
                                       16
<PAGE>
which may be provided by the Distributor, DWR, its affiliates and other Selected
Broker-Dealers  under the  Plan include: (1)  compensation to,  and expenses of,
account executives and other employees of DWR and other Selected Broker-Dealers,
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.
 
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  securities  are  traded on  more  than  one
exchange,  the securities are  valued on the exchange  designated as the primary
market pursuant  to procedures  adopted  by the  Trustees);  and (2)  all  other
portfolio  securities for  which over-the-counter market  quotations are readily
available are valued  at the latest  available bid  price prior to  the time  of
valuation.   When  market  quotations  are   not  readily  available,  including
circumstances under which it is determined  by the Investment Manager that  sale
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 as of the
morning of valuation.  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.
    
 
    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  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 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
 
                                       17
<PAGE>
be paid in cash. Such dividends and distributions will be paid in shares of  the
Fund  at net  asset value  per share. At  any time  an investor  may request the
Transfer Agent  in writing  to have  subsequent dividends  and/or capital  gains
distributions  paid  to  the investor  in  cash  rather than  shares.  To assure
sufficient time to process  the change, such request  should be received by  the
Transfer  Agent at least five business days  prior to the payment date for which
it commences to take effect. In the case of recently purchased shares for  which
registration  instructions  have  not been  received  on the  record  date, cash
payments will be made to DWR or other Selected Broker-Dealer through whom shares
were purchased.
 
    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 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  Fund's 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.
 
    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
the  self-employed,  eligible  Individual  Retirement  Accounts  and   Custodial
Accounts  under Section 403(b)(7) of the Internal Revenue Code. Adoption of such
plans should  be  on  advice  of  legal counsel  or  tax  adviser.  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.   An "Exchange  Privilege", that  is, the  privilege of
exchanging shares of certain  Dean Witter Funds for  shares of the Fund,  exists
whereby  shares  of  various Dean  Witter  Funds which  are  open-end investment
companies sold with either a front-end (at time of purchase) sales charge ("FESC
funds") or a contingent deferred sales charge ("CDSC funds") may be redeemed  at
their  next calculated net asset value and the proceeds of the redemption may be
used to purchase shares of the Fund, Dean Witter Short-Term U.S. Treasury Trust,
Dean Witter Intermediate Term U.S.  Treasury Trust, Dean Witter Balanced  Income
Fund,  Dean Witter Balanced Growth Fund,  and Dean Witter Limited Term Municipal
Trust and shares of five  Dean Witter Funds which  are money market funds:  Dean
Witter  Tax-Free Daily  Income Trust, Dean  Witter U.S.  Government Money Market
Trust, Dean Witter Liquid Asset Fund Inc., Dean Witter California Tax-Free Daily
Income Trust and Dean Witter New York Municipal Money Market Trust (which eleven
funds including  the  Fund  are  hereinafter collectively  referred  to  as  the
"Exchange  Funds"). An exchange from an FESC fund  or a CDSC fund to an Exchange
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 an FESC fund or a CDSC fund, shares of the FESC fund or the CDSC  fund
are redeemed at their next calculated net asset value
    
 
                                       18
<PAGE>
and  exchanged for  shares of  the money  market fund  at their  net asset value
determined the  following business  day. Subsequently,  shares of  the  Exchange
Funds received in an exchange for shares of an FESC fund (regardless of the type
of  fund originally purchased) may  be redeemed and exchanged  for shares of the
other Exchange Funds, FESC funds or  CDSC funds (however, shares of CDSC  funds,
including  shares acquired  in exchange  for (i)  shares of  FESC funds  or (ii)
shares of the Exchange Funds which were acquired in exchange for shares of  FESC
funds,  may not be exchanged for shares  of FESC funds). Additionally, shares of
the Exchange Funds 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 the  other Exchange Funds  or CDSC funds.  Ultimately, any applicable
contingent deferred sales charge ("CDSC") will  have to be paid upon  redemption
of shares originally purchased from a CDSC fund. (If shares of the Exchange Fund
received  in  exchange for  shares  originally purchased  from  a CDSC  fund are
exchanged for shares of another CDSC fund having a different CDSC schedule  than
that  of the CDSC fund from which  the Exchange Fund's shares were acquired, the
shares will be subject to the higher  CDSC schedule.) During the period of  time
the  shares originally  purchased from  a CDSC fund  remain in  an Exchange Fund
(calculated from the last  day of the  month in which  the Exchange Fund  shares
were  acquired), the holding period (for the  purpose of determining the rate of
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 the  CDSC fund are
reacquired. Thus,  the CDSC  is based  upon the  period of  time (calculated  as
described  above)  the  shareholder  was  invested  in  a  CDSC  fund. Exchanges
involving FESC funds or CDSC funds may be made after the shares of the FESC fund
or 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 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.
 
    The  current prospectus for each  fund describes its investment objective(s)
and policies, and shareholders  should obtain one and  read 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 has  realized 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 above  Dean
Witter   Funds  (for  which  the   Exchange  Privilege  is  available)  pursuant
 
                                       19
<PAGE>
   
to this Exchange  Privilege by  contacting their  DWR or  other Selected  Dealer
account  executive (no Exchange Privilege Authorization Form is required). Other
shareholders (and those who are clients  of DWR or other Selected  Broker-Dealer
but  who wish to make exchanges directly  by writing or telephoning the Transfer
Agent) must complete  and forward to  the Transfer Agent  an Exchange  Privilege
Authorization  Form, copies of which may be  obtained from the Fund, 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 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 of the other
Dean Witter Funds in the past.
 
    Additional information on the above  is available from an account  executive
of DWR or another Selected Broker-Dealer or from the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    REDEMPTION.   Shares of the Fund can be redeemed for cash at any time at its
respective current net asset  value per share (without  any redemption or  other
charge).  If  shares  are  held  in  a  shareholder's  account  without  a share
certificate, a written request for  redemption is required. If certificates  are
held  by  the  shareholder,  the  shares may  be  redeemed  by  surrendering the
certificates with a written request for redemption. The share certificate, or an
accompanying stock power, and the request for redemption, must be signed by  the
shareholder  or shareholders exactly as the  shares are registered. Each request
for redemption, whether or not accompanied by a share certificate, must be  sent
to  the Fund's Transfer Agent at P.O Box  983, Jersey City, NJ 07303, which will
redeem the shares  at their net  asset value next  determined (see "Purchase  of
Fund Shares -- Determination of Net Asset Value") after it receives the request,
and  certificates, if any, in good  order. Any redemption request received after
such determination will be redeemed at the price next determined. The term "good
order" means that the share certificates, 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  will  be
accepted.  A stock power may be obtained from any dealer or commercial bank. The
Fund  may  change   the  signature   guarantee  requirements   upon  notice   to
shareholders, which may be by means of a new Prospectus.
    Whether  certificates are held  by the shareholder  or shares are  held in a
shareholder's account, if the proceeds are to  be paid to any person other  than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor for the account of the shareholder),
partner-
 
                                       20
<PAGE>
ship,  trust or fiduciary, or  sent to the shareholder  at an address other than
the registered address, signature(s) 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  an  eligible
guarantor).
    REPURCHASE.    DWR  and  other  Selected  Broker-Dealers  are  authorized to
repurchase shares represented by a share  certificate which is delivered to  any
of  their  offices.  Shares held  in  a  shareholder's account  without  a share
certificate may also  be repurchased  by DWR and  other Selected  Broker-Dealers
upon  the telephonic request of the shareholder. The repurchase price is the net
asset value next determined  (see "Purchase of Fund  Shares -- Determination  of
Net  Asset  Value") after  such repurchase  order  is received  by DWR  or other
Selected Broker-Dealer. Payment for shares repurchased  may be made by the  Fund
to  the Distributor  for the account  of the  shareholder. The offer  by DWR and
other Selected  Broker-Dealers to  repurchase shares  from shareholders  may  be
suspended  without notice by them  at any time. In  that event, shareholders may
redeem their shares through the Fund's  Transfer Agent as set forth above  under
"Redemption."
    PAYMENT  FOR SHARES REDEEMED  OR REPURCHASED.   Payment for shares presented
for repurchase  or redemption  will be  made by  check within  seven days  after
receipt  by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended  under
unusual circumstances. If the shares to be redeemed have recently been purchased
by check, payment of the redemption proceeds may be delayed for the minimum time
needed  to verify that the check used  for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer  Agent).
Shareholders   maintaining  margin   accounts  with  DWR   or  another  Selected
Broker-Dealer are referred to their account executive regarding restrictions  on
redemption of shares of the Fund pledged in the margin account.
    REINSTATEMENT  PRIVILEGE.   A  shareholder  who has  had  his or  her shares
redeemed or  repurchased and  has not  previously exercised  this  reinstatement
privilege  may,  within  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 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 to redeem, on 60 days'
notice and  at  net asset  value,  the shares  (other  than shares  held  in  an
Individual  Retirement Account or  custodial account under  Section 403(b)(7) of
the Internal Revenue Code) of any shareholder whose shares have a value of  less
than  $100 as a result  of redemptions or repurchases,  or such lesser amount as
may be  fixed by  the Trustees  or, in  the case  of an  account opened  through
EasyInvest-SM-,  if after twelve  months the shareholder  has invested less than
$1,000 in the account.  However, before the Fund  redeems such shares and  sends
the  proceeds to the shareholder, it will  notify the shareholder that the value
of the shares is less than the applicable amount and allow the shareholder sixty
days in which to make an additional investment in an amount which will  increase
the value of his or her account to at least the applicable amount or more before
the redemption is processed.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS  AND DISTRIBUTIONS.   The Fund declares dividends  on each day the
New York  Stock  Exchange is  open  for  business. Such  dividends  are  payable
monthly.  The  Fund intends  to distribute  substantially all  of its  daily net
investment income on an annual basis. Dividends from net capital gains, if  any,
will be paid at least once each year.
 
    Shareholders  may instruct  the Transfer  Agent (in  writing) to  have their
dividends paid out monthly
 
                                       21
<PAGE>
in cash. Processing of dividend checks begins immediately following the  monthly
payment  date. Shareholders who have requested to receive dividends in cash will
normally be sent their monthly dividend check  during the first ten days of  the
following month.
 
    TAXES.   Because the  Fund intends to  distribute all of  its net investment
income and net  short-term capital  gains to shareholders  and otherwise  remain
qualified  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.
 
    Shareholders  who are  required to pay  taxes on their  income will normally
have to pay federal income taxes,  and any applicable state and/or local  income
taxes,  on  the dividends  and distributions  they receive  from the  Fund. Such
dividends and  distributions, to  the  extent that  they  are derived  from  net
investment  income  and  net  short-term  capital  gains,  are  taxable  to  the
shareholder as ordinary  dividend income regardless  of whether the  shareholder
receives  such  distributions in  additional shares  or  in cash.  Any dividends
declared in  the  last quarter  of  any calendar  year  which are  paid  in  the
following  year prior to  February 1 will  be deemed, for  tax purposes, to have
been received by the shareholder in the prior year.
 
    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. It  is not  anticipated that any  portion of the
Fund's distributions will be  eligible for the  dividends received deduction  to
corporate shareholders.
 
    After  the  end  of  the  calendar  year,  shareholders  will  be  sent full
information on their dividends and capital gains distributions for tax purposes,
including information  as to  the portion  taxable as  ordinary income  and  the
portion taxable as long-term capital gains.
 
    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  who are not citizens or residents
of, or entities organized  in, the United States  may be subject to  withholding
taxes of up to 30% on certain payments received from the Fund.
 
    The   foregoing  discussion  relates  solely   to  the  federal  income  tax
consequences of an investment in the Fund. Distributions may also be subject  to
state  and local taxes; therefore, each shareholder is advised to consult his or
her own tax adviser.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From time to time the Fund may  quote its "yield" and/or its "total  return"
in  advertisements and sales literature. Both the  yield and the total return of
the Fund  are based  on historical  earnings and  are not  intended to  indicate
future  performance.  The yield  of the  Fund  is computed  by dividing  the 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 or over the life of  the
Fund,  if less than any  of the foregoing. Average  annual total return reflects
all income earned by  the Fund, any appreciation  or depreciation of the  Fund's
assets, all expenses incurred by the Fund and any
    
 
                                       22
<PAGE>
sales charges which would be incurred by redeeming shareholders, for the 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.
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. There  are
no  conversion,  pre-emptive  or  other subscription  rights.  In  the  event of
liquidation, each share of  beneficial interest of the  Fund is entitled to  its
portion of all of the Fund's assets after all debts and expenses have been paid.
The shares do not have cumulative voting rights.
    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, in the opinion of Massachusetts
counsel to the Fund, the risk to 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 option 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.

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
    The  Fund is a trust of the type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts  on
October 22, 1993.
 
THE INVESTMENT MANAGER
    Dean  Witter InterCapital Inc. (the "Investment Manager" or "InterCapital"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager. InterCapital  is a wholly-owned  subsidiary of Dean  Witter,
Discover  & Co. ("DWDC"), a Delaware  corporation. In an internal reorganization
which  took  place  in  January,   1993,  InterCapital  assumed  the   advisory,
administrative   and   management   activities  previously   performed   by  the
InterCapital Division  of Dean  Witter Reynolds  Inc. ("DWR"),  a  broker-dealer
affiliate  of InterCapital. (As hereinafter used in this Statement of Additional
Information, the terms  "InterCapital" and "Investment  Manager" refer to  DWR's
InterCapital  Division prior to  the internal reorganization  and to Dean Witter
InterCapital Inc. thereafter.) The daily management of the Fund is conducted  by
or  under the direction of  officers of the Fund  and of the Investment Manager,
subject to review of investments by  the Fund's Trustees. In addition,  Trustees
of  the  Fund provide  guidance on  economic factors  and interest  rate trends.

"Trustees and Officers".

(i) sub-adviser to Templeton Global Opportunities Trust, an open-end  investment
company;  (ii)  administrator  of The  BlackRock  Strategic Term  Trust  Inc., a
closed-end investment  company;  and  (iii)  sub-administrator  of  Mass  Mutual
Participation   Investors  and   Templeton  Global   Governments  Income  Trust,
closed-end investment companies.
    
 
    Pursuant to an  Investment Management Agreement  (the "Agreement") with  the
Investment  Manager, the Fund has retained  the Investment Manager to manage the
investment of  the  Fund's assets,  including  the  placing of  orders  for  the
purchase  and sale of  portfolio securities. The  Investment Manager obtains and
evaluates such  information  and  advice relating  to  the  economy,  securities
markets,  and  specific  securities  as  it  considers  necessary  or  useful to
continuously manage  the assets  of the  Fund in  a manner  consistent with  its
investment objective.
 
    Under  the  terms  of the  Agreement,  in  addition to  managing  the Fund's
investments, the Investment Manager  maintains certain of  the Fund's books  and
records  and  furnishes,  at its  own  expense, such  office  space, facilities,
equipment, clerical help and bookkeeping and certain legal services as the  Fund
may reasonably require in the conduct of its business, including the preparation
of  prospectuses,  statements of  additional  information, proxy  statements and
reports required  to be  filed  with federal  and state  securities  commissions
(except  insofar as the  participation or assistance  of independent accountants
and attorneys  is,  in the  opinion  of  the Investment  Manager,  necessary  or
desirable).  In  addition,  the  Investment Manager  pays  the  salaries  of all
personnel, including officers of the Fund,  who are employees of the  Investment
Manager.  The Investment Manager also bears the cost of telephone service, heat,
light, power and other utilities provided to the Fund.
 
    Effective December  31,  1993,  pursuant to  a  Services  Agreement  between
InterCapital  and DWSC, a wholly-owned subsidiary of InterCapital, DWSC began to
provide the administrative services to the Fund which were previously  performed
directly  by InterCapital. On April 17, 1995,  DWSC was reorganized in the State
of  Delaware,  necessitating  the  entry  into  a  new  Services  Agreement   by
InterCapital  and DWSC on such date.  The foregoing internal reorganizations did
not result in any change in the  nature or scope of the administrative  services
being  provided to the Fund  or any of the  fees being paid by  the Fund for the
overall services being performed under the terms of the existing Agreement.
 
    The Fund pays all expenses incurred in its operation. Expenses not expressly
assumed by the Investment Manager under  the Agreement or by the distributor  of
the  Fund's  shares,  Dean  Witter  Distributors  Inc.  ("Distributors"  or  the
"Distributor") (see "Purchase  of Fund Shares")  will be paid  by the Fund.  The
expenses borne by the Fund include, but are not limited to: charges and expenses
of  any  registrar; custodian,  stock  transfer and  dividend  disbursing agent;
brokerage commissions;  taxes; engraving  and  printing of  share  certificates;
registration costs of the Fund and its shares under federal and state securities
laws;  the cost and expense of printing, including typesetting, and distributing
Prospectuses  and  Statements  of  Additional   Information  of  the  Fund   and
supplements  thereto to the  Fund's shareholders; all  expenses of shareholders'
and  trustees'  meetings  and  of  preparing,  printing  and  mailing  of  proxy
statements  and reports to shareholders; fees and travel expenses of trustees or
members of  any  advisory  board or  committee  who  are not  employees  of  the
Investment  Manager or  any corporate affiliate  of the  Investment Manager; all
expenses incident to any dividend, withdrawal or redemption options; charges and
expenses of any outside service used for pricing of the Fund's shares; fees  and
expenses  of  legal  counsel, including  counsel  to  the trustees  who  are not
interested persons  of the  Fund or  of the  Investment Manager  (not  including
compensation  or  expenses  of attorneys  who  are employees  of  the Investment
Manager) and independent accountants; membership dues of industry  associations;
interest  on the Fund's  borrowings; postage; insurance  premiums on property or
personnel (including  officers and  trustees) of  the Fund  which inure  to  its
benefit;  extraordinary expenses including, but not limited to, legal claims and
liabilities and  litigation  costs  and  any  indemnification  relating  thereto
(depending  upon the nature of the legal claim, liability or lawsuit), the costs
of litigation,  payment  of  legal  claims  or  liabilities  or  indemnification
relating thereto; and all other costs of the Fund's operations.
 
                                       4

    The Investment Manager had undertaken from January 10, 1994 (commencement of
operations)  to  assume all  operating expenses  and  to waive  the compensation
provided for in its  Management Agreement until  such time as  the Fund had  $50
million of net assets or until December 31, 1995 whichever occurred first.
    
 
   
    The  Investment Manager has undertaken from January 1, 1996 through December
31, 1996 to continue to assume all operating expenses (except for any  brokerage
fees)  and to  continue to  waive compensation to  the extent  such expenses and
compensations exceed 1.0% of the Fund's daily net assets on an annualized basis.
    
 
   
    As full compensation for the services  and facilities furnished to the  Fund
and  expenses of the Fund  assumed by the Investment  Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the  annual
rate of 0.70% to the daily net assets of the Fund. For the fiscal period January
10, 1994 (commencement of the Fund's operations) through April 30, 1994, and for
the  fiscal years ended April  30, 1995 the fees  payable under the Agreement of
$73,373 and  $264,109,  respectively, were  waived  by the  Investment  Manager,
pursuant  to its undertakings  described above. For the  fiscal year ended April
30, 1996, the fees payable under  the Management Agreement amounted to  $234,741
of  which $180,434 was waived by the Investment Manager pursuant to undertakings
described above.
    
 
   
    Pursuant to the Agreement, total operating expenses of the Fund are  subject
to  applicable limitations under rules and  regulations of states where the Fund
is authorized to sell its shares. Therefore, operating expenses of the Fund  are
effectively  subject to such limitations as the same may be amended from time to
time. Presently,  the most  restrictive limitation  is as  follows: If,  in  any
fiscal  year,  the  total operating  expenses  of  a fund,  exclusive  of taxes,
interest, brokerage fees, distribution fees  and extraordinary expenses (to  the
extent  permitted by applicable  state securities laws  and regulations), exceed
2 1/2% of  the first $30,000,000  of average daily  net assets, 2%  of the  next
$70,000,000  and 1 1/2% of any  excess over $100,000,000, the Investment Manager
will reimburse such fund  for the amount  of such excess.  Such amount, if  any,
will  be calculated  daily and  credited on  a monthly  basis. The  Fund did not
exceed such  limitation  for  the  periods January  10,  1994  (commencement  of
operations)  through April 30,  1994, and for  the fiscal years  ended April 30,
1995 and April 30, 1996.
    
 
    The Agreement  provides that  in  the absence  of willful  misfeasance,  bad
faith, gross negligence or reckless disregard of its obligations thereunder, the
Investment Manager is not liable to the Fund or any of its investors for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its  investors. The  Agreement in no  way restricts the  Investment Manager from
acting as investment manager or adviser to others.
 
    The Investment Manager paid the organizational expenses of the Fund incurred
prior to  the  offering of  the  Fund's shares.  The  Fund agreed  to  bear  and
reimburse the Investment Manager for such expenses, which totalled approximately
$160,000. The Fund has deferred and is amortizing the reimbursed expenses on the
straight  line method over  a period not to  exceed five years  from the date of
commencement of the Fund's operations.
 
    The Agreement was initially approved by the Trustees and by InterCapital  as
the sole shareholder on December 2, 1993. The Agreement may be terminated at any
time,  without penalty, on thirty  days' notice by the  Trustees of the Fund, by
the holders of a majority of the  outstanding shares of the Fund, as defined  in
the Investment Company Act of 1940, as amended (the "Act"), or by the Investment
Manager.  The  Agreement  will  automatically  terminate  in  the  event  of its
assignment (as defined in the Act).
 
   
    Under its terms, the  Agreement had an initial  term ending April 30,  1995,
and  will continue  from year  to year  thereafter, provided  continuance of the
Agreement is approved at least annually by the vote of the holders of a majority
of the outstanding shares of the Fund, as defined in the Act, or by the Trustees
of the Fund; provided that in either event such continuance is approved annually
by the vote of a majority of the Trustees of the Fund who are not parties to the
Agreement or "interested persons" (as defined in the Act) of any such party (the
"Independent Trustees"), which vote must be  cast in person at a meeting  called
for  the purpose of voting on such approval. The most recent continuation of the
Agreement until April 30,
    
 
                                       5
<PAGE>
   
1997 was approved  by the  Trustees of  the Fund,  including a  majority of  the
Independent Trustees, at their meeting held on April 17, 1996.
    
 
    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR.  The Fund has  agreed that DWR or  its parent companies may  use, or at any
time permit others to use, the name "Dean Witter". The Fund has also agreed that
in the event the investment  management contract between the Investment  Manager
and the Fund is terminated, or if the affiliation between the Investment Manager
and  its parent companies is terminated, the  Fund will eliminate the name "Dean
Witter" from its  name if the  Investment Manager, DWR  or its parent  companies
shall so request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
    
 
   
    The Board of Trustees consists of nine (9) trustees. These same  individuals
also  serve as directors or  trustees for all of the  Dean Witter Funds, and are
referred to in this  section as Trustees.  As of the date  of this Statement  of
Additional  Information, there are a total of 81 Dean Witter Funds, comprised of
121 portfolios. As of May 31, 1996,  the Dean Witter Funds had total net  assets
of approximately $    billion and more than five million shareholders.
    
 
   
    Seven  Trustees (77%  of the total  number) have no  affiliation or business
connection with InterCapital or any of its affiliated persons and do not own any
stock or other securities issued  by InterCapital's parent company, DWDC.  These
are  the "disinterested" or "independent" Trustees.  The other two Trustees (the
"management Trustees")  are  affiliated  with  InterCapital.  Four  of  the  six
independent Trustees are also Independent Trustees of the TCW/DW Funds.
    
 
   
    Law and regulation establish both general guidelines and specific duties for
the  Independent Trustees.  The Dean Witter  Funds seek  as Independent Trustees
individuals of distinction  and experience in  business and finance,  government
service  or academia; these are people whose advice and counsel are in demand by
others and for  whom there is  often competition.  To accept a  position on  the
Funds'  Boards, such individuals may reject other attractive assignments because
the Funds make  substantial demands  on their time.  Indeed, by  serving on  the
Funds'  Boards, certain Trustees who would  otherwise be qualified and in demand
to serve on bank boards would be prohibited by law from doing so.
    
 
   
    All of the Independent Trustees serve as members of the Audit Committee  and
the  Committee of the Independent Trustees. Three  of them also serve as members
of the Derivatives Committee. During the calendar year ended December 31,  1995,
the  three Committees held a combined  total of fifteen meetings. The Committees
hold some  meetings at  InterCapital's offices  and some  outside  InterCapital.
Management  Trustees or  officers do not  attend these meetings  unless they are
invited for purposes of furnishing information or making a report.
    
 
   
    The Committee of the  Independent Trustees is  charged with recommending  to
the  full Board approval  of management, advisory  and administration contracts,
Rule 12b-1  plans  and  distribution and  underwriting  agreements;  continually
reviewing  Fund performance;  checking on  the pricing  of portfolio securities,
brokerage commissions, transfer agent costs  and performance, and trading  among
Funds  in the  same complex; and  approving fidelity bond  and related insurance
coverage and allocations, as well as other matters that arise from time to time.
The Independent Trustees are required to select and nominate individuals to fill
any Independent Trustee vacancy on the Board  of any Fund that has a Rule  12b-1
plan of distribution. Most of the Dean Witter Funds have such a plan.
    
 
   
    The  Audit  Committee is  charged with  recommending to  the full  Board the
engagement  or  discharge  of  the  Fund's  independent  accountants;  directing
investigations  into matters  within the  scope of  the independent accountants'
duties, including the power  to retain outside  specialists; reviewing with  the
independent  accountants the audit plan and  results of the auditing engagement;
approving professional  services provided  by  the independent  accountants  and
other  accounting firms prior to the performance of such services; reviewing the
independence of the independent accountants; considering the range of audit  and
non-audit  fees;  reviewing  the  adequacy  of  the  Fund's  system  of internal
controls; and preparing  and submitting  Committee meeting minutes  to the  full
Board.
    
 
   
    Finally,  the  Board of  each  Fund has  formed  a Derivatives  Committee to
establish parameters for and oversee the activities of the Fund with respect  to
derivative investments, if any, made by the Fund.

DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND THE AUDIT
COMMITTEE
    
 
   
    The  Chairman of  the Committee  of the  Independent Trustees  and the Audit
Committee maintains an  office at  the Funds' headquarters  in New  York. He  is
responsible  for keeping abreast of regulatory and industry developments and the
Funds' operations and management. He  screens and/or prepares written  materials
and  identifies  critical  issues  for  the  Independent  Trustees  to consider,
develops agendas  for Committee  meetings,  determines the  type and  amount  of
information  that the Committees will need to form a judgment on various issues,
and arranges to have  that information furnished to  Committee members. He  also
arranges  for  the services  of independent  experts and  consults with  them in
advance of meetings  to help  refine reports and  to focus  on critical  issues.
Members of the Committees believe that the person who serves as Chairman of both
Committees  and guides their efforts is  pivotal to the effective functioning of
the Committees.
    
 
   
    The Chairman of the  Committees also maintains  continuous contact with  the
Funds' management, with independent counsel to the Independent Trustees and with
the  Funds' independent auditors.  He arranges for a  series of special meetings
involving the  annual  review  of  investment  advisory,  management  and  other
operating  contracts of  the Funds  and, on  behalf of  the Committees, conducts
negotiations with the Investment Manager and other service providers. In effect,
the Chairman of the  Committees serves as a  combination of chief executive  and
support staff of the Independent Trustees.
    
 
   
    The  Chairman of  the Committee  of the  Independent Trustees  and the Audit
Committee is  not  employed by  any  other  organization and  devotes  his  time
primarily  to the  services he  performs as  Committee Chairman  and Independent
Trustee of the Dean  Witter Funds and  as an Independent  Trustee of the  TCW/DW
Funds. The current Committee Chairman has had more than 35 years experience as a
senior executive in the investment company industry.
    
 
   
ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL DEAN
WITTER FUNDS
    
 
   
    The  Independent Trustees and the Funds'  management believe that having the
same Independent  Trustees  for  each  of  the  Dean  Witter  Funds  avoids  the
duplication  of  effort  that  would  arise  from  having  different  groups  of
individuals serving as  Independent Trustees for  each of the  Funds or even  of
sub-groups  of Funds.  They believe  that having  the same  individuals serve as
Independent Trustees of  all the  Funds tends  to increase  their knowledge  and
expertise regarding matters which affect the Fund complex generally and enhances
their  ability  to negotiate  on behalf  of  each Fund  with the  Fund's service
providers. This arrangement also precludes the possibility of separate groups of
Independent Trustees arriving at conflicting decisions regarding operations  and
management  of the  Funds and  avoids the cost  and confusion  that would likely
ensue. Finally, having the  same Independent Trustees serve  on all Fund  Boards
enhances  the ability of  each Fund to  obtain, at modest  cost to each separate
Fund, the services of Independent Trustees, and a Chairman of their  Committees,
of  the caliber, experience and business acumen  of the individuals who serve as
Independent Trustees of the Dean Witter Funds.
    
 
   
COMPENSATION OF INDEPENDENT TRUSTEES
    
 
   
    The Fund pays each Independent  Trustee an annual fee  of $1,000 plus a  per
meeting  fee of $50 for  meetings of the Board of  Trustees or committees of the
Board of Trustees attended  by the Trustee  (the Fund pays  the Chairman of  the
Audit  Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent  Trustees an  additional  annual fee  of  $2,400, in  each  case
inclusive of the Committee meeting fees). The Fund also reimburses such Trustees
for  travel and other out-of-pocket expenses incurred by them in connection with
attending such meetings. Trustees and officers of the Fund who are or have  been
employed  by  the  Investment  Manager  or  an  affiliated  company  receive  no
compensation or expense reimbursement from the Fund.

<PAGE>
   
    At such time as  the Fund has been  in operation, and has  paid fees to  the
Independent  Trustees, for  a full  fiscal year,  and assuming  that during such
fiscal year the Fund holds  the same number of  Board and committee meetings  as
were held by the other Dean Witter Funds during the calendar year ended December
31, 1995, it is estimated that the compensation paid to each Independent Trustee
during such fiscal year will be the amount shown in the following table:

    As  of the date of this Statement  of Additional Information, 57 of the Dean
Witter Funds, not including  the Fund, have adopted  a retirement program  under
which  an Independent Trustee who retires after  serving for at least five years
(or such lesser  period as may  be determined  by the Board)  as an  Independent
Director  or Trustee  of any  Dean Witter Fund  that has  adopted the retirement
program (each such Fund referred to as an "Adopting Fund" and each such  Trustee
referred  to as an  "Eligible Trustee") is entitled  to retirement payments upon
reaching the eligible retirement age (normally, after attaining age 72).  Annual
payments  are based  upon length  of service.  Currently, upon  retirement, each
Eligible Trustee is entitled to receive from the Adopting Fund, commencing as of
his or her retirement date and continuing for the remainder of his or her  life,
an  annual retirement benefit (the  "Regular Benefit") equal to  25.0% of his or
her Eligible Compensation plus 0.4166666% of such Eligible Compensation for each

full month of service as an Independent Director or Trustee of any Adopting Fund
in excess of five years up to a maximum of 50.0% after ten years of service. The
foregoing percentages may be changed by
    
   
the Board.(4) "Eligible  Compensation" is  one-fifth of  the total  compensation
earned  by such Eligible  Trustee for service  to the Adopting  Fund in the five
year period prior  to the date  of the Eligible  Trustee's retirement.  Benefits
under the retirement program are not secured or funded by the Adopting Funds.

(4)  An Eligible Trustee may  elect alternate payments of  his or her retirement
    benefits based upon the  combined life expectancy  of such Eligible  Trustee
    and his or her spouse on the date of such Eligible Trustee's retirement. The
    amount  estimated to be payable under  this method, through the remainder of
    the later of  the lives of  such Eligible  Trustee and spouse,  will be  the
    actuarial  equivalent  of the  Regular  Benefit. In  addition,  the Eligible
    Trustee may elect that the  surviving spouse's periodic payment of  benefits
    will  be equal  to either 50%  or 100%  of the previous  periodic amount, an
    election that, respectively,  increases or decreases  the previous  periodic
    amount  so that the  resulting payments will be  the actuarial equivalent of
    the Regular Benefit.

INVESTMENT PRACTICES AND POLICIES
    
- --------------------------------------------------------------------------------
 
    As  stated  in the  Prospectus,  the Fund  seeks  to achieve  its investment
objective  by   investing  in   short-term,  fixed-income   securities  with   a
dollar-weighted  average  portfolio  maturity  of  less  than  three  years.  In
calculating the maturity of certain  of the Fund's securities (E.G.,  securities
with a demand feature), the Fund will utilize the provisions of Rule 2a-7 of the
Act.
 
    The  maturity of  a portfolio  instrument shall be  deemed to  be the period
remaining (calculated from the trade date or such other date on which the Fund's
interest in the instrument is subject to market action) until the date noted  on
the  face of the  instrument as the date  on which the  principal amount must be
paid, or in the case of an  instrument called for redemption, the date on  which
the redemption payment must be made, except that:
 
        (1)  An instrument  that is  issued or  guaranteed by  the United States
    government or  any agency  thereof which  has a  variable rate  of  interest
    readjusted    no    less   frequently    than    every   762    days   shall
 
                                       12
<PAGE>
    be deemed to have a  maturity equal to the  period remaining until the  next
    readjustment of the interest rate.
 
        (2)  A  variable  rate  instrument, the  principal  amount  of  which is
    scheduled on the face of the instrument  to be paid in 397 calendar days  or
    less  shall be deemed to have a maturity equal to the period remaining until
    the next readjustment of the interest rate.
 
        (3) A variable rate instrument that is subject to a demand feature shall
    be deemed to have  a maturity equal  to the longer  of the period  remaining
    until  the next  readjustment of the  interest rate or  the period remaining
    until the principal amount can be recovered through demand.
 
        (4) A floating rate instrument that is subject to a demand feature shall
    be deemed  to  have a  maturity  equal to  the  period remaining  until  the
    principal amount can be recovered through demand.
 
        (5)  A repurchase agreement shall be deemed  to have a maturity equal to
    the period  remaining  until  the  date  on  which  the  repurchase  of  the
    underlying securities is scheduled to occur, or, where no date is specified,
    but  the agreement is subject to a demand, the notice period applicable to a
    demand for the repurchase of the securities.
 
        (6) A portfolio lending agreement shall be treated as having a  maturity
    equal  to the period remaining until the date on which the loaned securities
    are scheduled  to  be returned,  or  where no  date  is specified,  but  the
    agreement is subject to demand, the notice period applicable to a demand for
    the return of the loaned securities.
 
    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.
These contracts are traded  in the interbank  market conducted directly  between
currency  traders  (usually large,  commercial and  investment banks)  and their
customers. Such forward contracts will only  be entered into with United  States
banks  and their foreign branches or foreign banks whose assets total $1 billion
or more.  A  forward contract  generally  has  no deposit  requirement,  and  no
commissions are charged at any stage for trades.
 
    When  management  of the  Fund believes  that the  currency of  a particular
foreign country may suffer  a substantial movement against  the U.S. dollar,  it
may  enter into a  forward contract to purchase  or sell, for  a fixed amount of
dollars or  other currency,  the amount  of foreign  currency approximating  the
value  of some  or all  of the Fund's  portfolio securities  denominated in such
foreign currency.
 
    The Fund will enter into forward contracts under various circumstances. When
the Fund  enters  into  a contract  for  the  purchase or  sale  of  a  security
denominated  in a foreign currency, it may, for example, desire to "lock in" the
price of the security in U.S. dollars  or some other foreign currency which  the
Fund  is  temporarily  holding in  its  portfolio.  By entering  into  a forward
contract for  the purchase  or sale,  for a  fixed amount  of dollars  or  other
currency,  of the amount of foreign currency involved in the underlying security
transactions, the Fund will  be able to protect  itself against a possible  loss
resulting  from an adverse change in the relationship between the U.S. dollar or
other currency which is being used for the security purchase (by the Fund or the
counterparty) and  the foreign  currency in  which the  security is  denominated
during  the period between the  date on which the  security is purchased or sold
and the date on which payment is made or received.
 
    At other times, when,  for example, the  Fund's Investment Manager  believes
that  the  currency of  a particular  foreign country  may suffer  a substantial
decline against the  U.S. dollar or  some other foreign  currency, the Fund  may
enter  into a forward contract  to sell, for a fixed  amount of dollars or other
currency, the amount of foreign currency approximating the value of some or  all
of the Fund's securities
 
                                       13
<PAGE>
holdings  (or  securities  which  the  Fund  has  purchased  for  its portfolio)
denominated in such  foreign currency. Under  identical circumstances, the  Fund
may enter into a forward contract to sell, for a fixed amount of U.S. dollars or
other  currency, an amount of foreign currency  other than the currency in which
the securities to be hedged are  denominated approximating the value of some  or
all  of the portfolio  securities to be  hedged. This method  of hedging, called
"cross-hedging,"  will  be  selected  by  the  Investment  Manager  when  it  is
determined  that  the foreign  currency in  which  the portfolio  securities are
denominated has insufficient liquidity or is  trading at a discount as  compared
with some other foreign currency with which it tends to move in tandem.
 
   
    In  addition,  when  the Fund's  Investment  Manager  anticipates purchasing
securities at  some time  in  the future,  and wishes  to  lock in  the  current
exchange  rate of the currency in which those securities are denominated against
the U.S.  dollar or  some other  foreign currency,  the Fund  may enter  into  a
forward  contract to purchase an amount of currency  equal to some or all of the
value of the anticipated purchase, for a  fixed amount of U.S. dollars or  other
currency.  The  Fund  may,  however,  close  out  the  forward  contract without
purchasing the security which was the subject of the "anticipatory" hedge.
    
 
    The Fund will not enter into forward contracts or maintain a net exposure to
such contracts where the consummation of  the contracts would obligate the  Fund
to  deliver an amount of  foreign currency in excess of  the value of the Fund's
portfolio securities or other assets denominated in that currency. Under  normal
circumstances,  consideration  of the  prospect  for currency  parities  will be
incorporated into  the longer  term  investment decisions  made with  regard  to
overall diversification strategies. However, the management of the Fund believes
that  it  is  important to  have  the  flexibility to  enter  into  such forward
contracts when it determines that the best interests of the Fund will be served.
The Fund's custodian bank will place  cash, U.S. Government securities or  other
appropriate  liquid high  grade debt securities  in a segregated  account of the
Fund in an amount equal to the value of the Fund's total assets committed to the
consummation of forward contracts entered into under the circumstances set forth
above. If the value of the securities placed in the segregated account declines,
additional cash or securities will be placed in the account on a daily basis  so
that  the value of the  account will equal the  amount of the Fund's commitments
with respect to such contracts.
 
    Where, for example, the Fund is  hedging a portfolio position consisting  of
foreign  securities denominated in  a foreign currency  against adverse exchange
rate moves vis-a-vis the  U.S. dollar, at the  maturity of the forward  contract
for  delivery by the  Fund of a foreign  currency, the Fund  may either sell the
portfolio security and make delivery of  the foreign currency, or it may  retain
the  security and  terminate its contractual  obligation to  deliver the foreign
currency by purchasing an  "offsetting" contract with  the same currency  trader
obligating  it to purchase,  on the same  maturity date, the  same amount of the
foreign currency (however, the  ability of the Fund  to terminate a contract  is
contingent  upon the willingness  of the currency trader  with whom the contract
has been entered into to permit an offsetting transaction). It is impossible  to
forecast  the  market value  of portfolio  securities at  the expiration  of the
contract. Accordingly, it may be necessary  for the Fund to purchase  additional
foreign  currency on the spot market (and  bear the expense of such purchase) if
the market value of the security is less than the amount of foreign currency the
Fund is obligated to deliver and if a decision is made to sell the security  and
make  delivery of the foreign currency. Conversely,  it may be necessary to sell
on the spot market some  of the foreign currency received  upon the sale of  the
portfolio  securities if its market value exceeds the amount of foreign currency
the Fund is obligated to deliver.
 
    If the Fund retains  the portfolio securities and  engages in an  offsetting
transaction,  the Fund will  incur a gain or  loss to the  extent that there has
been movement in  spot or forward  contract prices.  If the Fund  engages in  an
offsetting transaction, it may subsequently enter into a new forward contract to
sell  the  foreign currency.  Should forward  prices  decline during  the period
between the Fund's entering into  a forward contract for  the sale of a  foreign
currency  and the date it enters into an offsetting contract for the purchase of
the foreign currency, the Fund  will realize a gain to  the extent the price  of
the  currency it  has 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.
 
                                       14
<PAGE>
    If the Fund purchases a fixed-income  security which is denominated in  U.S.
dollars  but which will pay  out its principal based upon  a formula tied to the
exchange rate  between the  U.S. dollar  and a  foreign currency,  it may  hedge
against  a decline  in the principal  value of  the security by  entering into a
forward contract to  sell an amount  of the relevant  foreign currency equal  to
some or all of the principal value of the security.
 
    At  times when  the Fund  has written  a call  option on  a security  or the
currency in  which it  is  denominated, it  may wish  to  enter into  a  forward
contract  to purchase  or sell  the foreign  currency in  which the  security is
denominated. A  forward contract  would,  for example,  hedge  the risk  of  the
security on which a call option has been written declining in value to a greater
extent  than the  value of the  premium received  for the option.  The Fund will
maintain with its Custodian at all  times, cash, U.S. Government securities,  or
other  appropriate high grade debt obligations  in a segregated account equal in
value to  all  forward  contract obligations  and  option  contract  obligations
entered into in hedge situations such as this.
 
    Although  the Fund values its assets daily in terms of U.S. dollars, it does
not intend to convert its holdings of foreign currencies into U.S. dollars on  a
daily  basis. It will, however, do so from time to time, and investors should be
aware of the costs of currency conversion. Although foreign exchange dealers  do
not  charge a fee for  conversion, they do realize a  profit based on the spread
between the prices at which they are buying and selling various currencies. Thus
a dealer may offer  to sell a foreign  currency to the Fund  at one rate,  while
offering  a  lesser rate  of  exchange should  the  Fund desire  to  resell that
currency to the dealer.
 
    In all  of  the above  circumstances,  if the  currency  in which  the  Fund
securities  holdings (or anticipated portfolio securities) are denominated rises
in value with respect to the currency  which is being purchased (or sold),  then
the  Fund will have realized fewer gains than  had the Fund not entered into the
forward contracts.  Moreover,  the  precise matching  of  the  forward  contract
amounts and the value of the securities involved will not generally be possible,
since the future value of such securities in foreign currencies will change as a
consequence  of market  movements in the  value of those  securities between the
date the forward contract is entered into  and the date it matures. The Fund  is
not  required  to  enter  into  such transactions  with  regard  to  its foreign
currency-denominated securities and will not do so unless deemed appropriate  by
the  Investment  Manager.  The Fund  generally  will  not enter  into  a forward
contract with  a term  of greater  than one  year, although  it may  enter  into
forward  contracts for periods of  up to five years. The  Fund may be limited in
its ability to enter  into hedging transactions  involving forward contracts  by
the  Internal Revenue Code (the  "Code") requirements relating to qualifications
as a regulated  investment company (see  "Dividends, Distributions and  Taxes").
The  Fund has not and does not intend  to, in the foreseeable future, enter into
forward contracts involving greater than 5% of its net assets.
 
    REPURCHASE AGREEMENTS.  When cash may be  available for only a few days,  it
may  be invested by the Fund in repurchase  agreements until such time as it may
otherwise be  invested  or used  for  payments of  obligations  of the  Fund.  A
repurchase  agreement may  be viewed as  a type  of secured lending  by the Fund
which typically involves the  acquisition by the  Fund of government  securities
from  a  selling  financial  institution  such  as  a  bank,  savings  and  loan
association or broker-dealer.  The agreement  provides that the  Fund will  sell
back  to  the  institution,  and  that  the  institution  will  repurchase,  the
underlying security ("collateral") at a specified  price and at a fixed time  in
the  future, usually  not more than  seven days  from the date  of purchase. The
collateral will be  maintained in  a segregated account  and will  be marked  to
market daily to determine that the full value of the collateral, as specified in
the  agreement,  does  not  decrease below  the  repurchase  price  plus accrued
interest. If such decrease  occurs, additional collateral will  be added to  the
account  to maintain  full collateralization. In  the event  the original seller
defaults on its  obligations to  repurchase, as a  result of  its bankruptcy  or
otherwise, the Fund will seek to sell the collateral, which action could involve
costs  or delays. In such case, the  Fund's ability to dispose of the collateral
to recover its investment may be restricted or delayed.
 
                                       15
<PAGE>
    The Fund will, when received, accrue interest from the institution until the
time when the repurchase is to occur.  Although such date is deemed by the  Fund
to  be the maturity date of a repurchase agreement, the maturities of securities
subject to repurchase agreements  are not subject to  any limits and may  exceed
one year.
 
    When  repurchase agreements involve certain risks not associated with direct
investments in  debt  securities,  each  Fund  follows  procedures  designed  to
minimize  such risks. Repurchase agreements will  be transacted only with large,
well-capitalized and  well-established  financial institutions  whose  financial
condition  will be continuously  monitored by the  Investment Manager subject to
procedures established by  the Trustees.  The procedures also  require that  the
collateral underlying the agreement be specified.
 
    WHEN-ISSUED  AND DELAYED  DELIVERY SECURITIES  AND FORWARD  COMMITMENTS.  As
discussed in  the Prospectus,  from time  to  time, in  the ordinary  course  of
business,  the Fund may purchase securities on a when-issued or delayed delivery
basis or may purchase  or sell securities on  a forward commitment  basis--i.e.,
delivery  and payment  can take  place a  month or  more after  the date  of the
transactions. The securities so purchased are subject to market fluctuation  and
no  interest accrues to  the purchaser during  this period. While  the Fund will
only  purchase  securities  on  a  when-issued,  delayed  delivery  or   forward
commitment  basis with the  intention of acquiring the  securities, the Fund may
sell the securities before  the settlement date, if  it is deemed advisable.  At
the  time the Fund makes the commitment  to purchase securities on a when-issued
or delayed delivery basis, the Fund  will record the transaction and  thereafter
reflect the value, each day, of such security in determining the net asset value
of the Fund. At the time of delivery of the securities, the value may be more or
less  than the purchase price. The Fund will also establish a segregated account
with the Fund's custodian  bank in which it  will continuously maintain cash  or
U.S.  Government securities or other high  grade debt portfolio securities equal
in value to  commitments for  such when-issued or  delayed delivery  securities;
subject  to this  requirement, the  Fund may  purchase securities  on such basis
without limit. An increase in the  percentage of the Fund's assets committed  to
the  purchase  of securities  on  a when-issued  or  delayed delivery  basis may
increase the volatility of  the Fund's net asset  value. The Investment  Manager
and  the Trustees do not believe that any  Fund's net asset value or income will
be adversely affected by its purchase of securities on such basis.
 
    REVERSE REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.   The  Fund may  also  use
reverse  repurchase  agreements  and  dollar rolls  as  part  of  its investment
strategy. Reverse repurchase agreements involve  sales by the Fund of  portfolio
assets  concurrently with an agreement by the Fund to repurchase the same assets
at a later date at a fixed price. Generally, the effect of such a transaction is
that the Fund  can recover all  or most of  the cash invested  in the  portfolio
securities  involved during the term of  the reverse repurchase agreement, while
it will be  able to  keep the interest  income associated  with those  portfolio
securities.  Such transactions are only advantageous if the interest cost to the
Fund of the reverse  repurchase transaction is less  than the cost of  obtaining
the cash otherwise.
 
    The  Fund may enter into dollar rolls in which the Fund sells securities for
delivery in  the  current  month  and  simultaneously  contracts  to  repurchase
substantially  similar (same type  and coupon) securities  on a specified future
date. During the roll period, the  Fund foregoes principal and interest paid  on
the  securities. The Fund  is compensated by the  difference between the current
sales price and the lower forward price for the future purchase (often  referred
to  as the "drop") as well as by the interest earned on the cash proceeds of the
initial sale.
 
    The Fund will  establish a  segregated account  with its  custodian bank  in
which  it will  maintain cash, U.S.  Government Securities or  other liquid high
grade debt obligations equal in value  to its obligations in respect of  reverse
repurchase agreements and dollar rolls. 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
 
                                       16
<PAGE>
agreements  and dollar rolls are  speculative techniques involving leverage, and
are considered borrowings by  the Fund. The  Fund has not to  date and does  not
intend  to  enter into  reverse  repurchase agreements  or  dollar rolls  in the
foreseeable future.
 
    LENDING OF  PORTFOLIO SECURITIES.    Consistent with  applicable  regulatory
requirements  and subject to Investment Restriction (6) below, the Fund may lend
its portfolio securities to brokers,  dealers and other financial  institutions,
provided  that such loans are callable  at any time by the  Fund, and are at all
times secured by  cash or money  market instruments, which  are maintained in  a
segregated  account pursuant to applicable regulations  and that are equal to at
least the  market  value,  determined  daily,  of  the  loaned  securities.  The
advantage  of such loans is that the Fund continues to receive the income on the
loaned securities while at  the same time earning  interest on the cash  amounts
deposited  as collateral, which will be  invested in short-term obligations. The
Fund will not lend portfolio securities having  a value of more than 10% of  its
total assets.
 
    A loan may be terminated by the borrower on one business day's notice, or by
the  Fund on four  business days' notice.  If the borrower  fails to deliver the
loaned securities within four days after  receipt of notice, the Fund could  use
the  collateral to replace the securities  while holding the borrower liable for
any excess  of replacement  cost  over collateral.  As  with any  extensions  of
credit,  there are  risks of delay  in recovery and  in some cases  even loss of
rights in the collateral should the borrower of the securities fail financially.
However, these loans of portfolio securities  will only be made of firms  deemed
by  the Fund's management  to be creditworthy  and when the  income which can be
earned from such loans  justifies the attendant risks.  Upon termination of  the
loan, the borrower is required to return the securities to the Fund. Any gain or
loss in the market price during the loan period will inure to the Fund.
 
    When  voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the  policy of calling the loaned securities,  in
whole  or in part  as may be appropriate,  to be delivered  within one day after
notice, to permit the exercise of such rights if the matters involved would have
a material effect on the Fund's  investment in such loaned securities. The  Fund
will  pay reasonable finder's,  administrative and custodian  fees in connection
with a loan of its securities. The Fund  has not to date and does not intend  to
lend any of its portfolio securities in the foreseeable future.
 
    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  or which  are otherwise not
readily marketable.  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 above policy on  purchase
of illiquid securities may be changed by the Fund's Trustees.
 
    The  Securities and Exchange Commission has recently adopted Rule 144A under
the Securities  Act of  1933, which  will  permit the  Fund to  sell  restricted
securities to qualified institutional buyers without limitation. The Trustees of
the  Fund  have adopted  procedures  for the  Investment  Manager to  utilize in
determining the liquidity of securities which may be sold pursuant to Rule 144A.
In addition,  the  Trustees have  determined  that, where  such  securities  are
determined to be liquid under these procedures, investment in such securities by
the  Fund shall not be subject to  the 5% limitation referred to above. However,
the Fund  has  not to  date  and does  not  intend to  purchase  any  restricted
securities in the foreseeable future.
 
    WARRANTS.    The  Fund may  acquire  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.  Warrants are,  in effect,  an option  to
purchase  equity securities at a specific  price, generally valid for a specific
period of time, and have no voting  rights, pay no dividends and have no  rights
with  respect to the corporation issuing them. The Fund has not to date and does
not intend to acquire any warrants in the forseeable future.
 
                                       17
<PAGE>
    CONVERTIBLE SECURITIES.  Certain of the fixed-income securities purchased by
the  Fund  may  be convertible  into  common  stock of  the  issuer. 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, will sell  at some premium  over its conversion  value.
(This  premium  represents  the  price  investors are  willing  to  pay  for the
privilege of purchasing a  fixed-income security with  a possibility of  capital
appreciation  due to the conversion  privilege.) At such times  the price of the
convertible security  will tend  to fluctuate  directly with  the price  of  the
underlying  equity security. Convertible securities may be purchased by the Fund
at varying price levels  above their investment  values and/or their  conversion
values  in keeping with the Fund's objective. The  Fund has not to date and does
not intend to invest in any convertible securities in the foreseeable future.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund  may write  covered call  options against  securities held  in  its
portfolio  and covered  put options on  eligible portfolio  securities and stock
indexes and purchase options of the same series to effect closing  transactions,
and  may hedge against potential changes in  the market value of investments (or
anticipated investments) and  facilitate the reallocation  of the Fund's  assets
into  and out of equities and fixed-income securities by purchasing put and call
options  on  portfolio  (or  eligible  portfolio)  securities  and  engaging  in
transactions involving futures contracts and options on such contracts. The Fund
may  also hedge against potential changes in  the market value of the currencies
in which  its  investments  (or  anticipated  investments)  are  denominated  by
purchasing  put  and  call  options on  currencies  and  engage  in transactions
involving currency futures contracts and options on such contracts. However, the
Fund has not to date  and does not intend to  enter into any options or  futures
transactions in the foreseeable future.
 
    Call  and put  options on  U.S. Treasury notes,  bonds and  bills and equity
securities  are  listed  on  Exchanges  and  are  written  in   over-the-counter
transactions  ("OTC options"). Listed options are issued by the Options Clearing
Corporation ("OCC")  and other  clearing entities  including foreign  exchanges.
Ownership  of a listed call option gives the  Fund the right to buy from the OCC
the underlying security covered by the option at the stated exercise price  (the
price per unit of the underlying security) by filing an exercise notice prior to
the  expiration date of the option. The writer (seller) of the option would then
have the obligation to sell to the OCC the underlying security at that  exercise
price prior to the expiration date of the option, regardless of its then current
market  price. Ownership of a listed put option would give the Fund the right to
sell the  underlying security  to the  OCC at  the stated  exercise price.  Upon
notice  of exercise  of the  put option, the  writer of  the put  would have the
obligation to purchase  the underlying  security from  the OCC  at the  exercise
price.
 
    OPTIONS  ON TREASURY BONDS AND NOTES.  Because trading in options written on
Treasury bonds and notes tends to center on the most recently auctioned  issues,
the  exchanges on which such securities  trade will not continue indefinitely to
introduce options with new expirations to replace expiring options on particular
issues. Instead,  the  expirations introduced  at  the commencement  of  options
trading  on a  particular issue will  be allowed  to run their  course, with the
possible addition of a  limited number of new  expirations as the original  ones
expire.  Options trading on each issue of bonds or notes will thus be phased out
as new options are listed on more recent issues, and options representing a full
range of expirations will not ordinarily  be available for every issue on  which
options are traded.
 
    OPTIONS ON TREASURY BILLS.  Because a deliverable Treasury bill changes from
week to week, writers of Treasury bill calls cannot provide in advance for their
potential exercise settlement obligations by
 
                                       18
<PAGE>
acquiring and holding the underlying security. However, if the Fund holds a long
position in Treasury bills with a principal amount of the securities deliverable
upon  exercise of the option, the position  may be hedged from a risk standpoint
by the writing of a call option. For so long as the call option is  outstanding,
the  Fund  will  hold  the  Treasury bills  in  a  segregated  account  with its
Custodian, so that they will be treated as being covered.
 
    OPTIONS ON FOREIGN CURRENCIES.  The  Fund may purchase and write options  on
foreign  currencies for  purposes similar  to those  involved with  investing in
forward foreign currency exchange  contracts. For example,  in order to  protect
against  declines  in  the  dollar  value  of  portfolio  securities  which  are
denominated in  a foreign  currency, the  Fund may  purchase put  options on  an
amount of such foreign currency equivalent to the current value of the portfolio
securities  involved. As a result, the Fund would be enabled to sell the foreign
currency for a  fixed amount of  U.S. dollars, thereby  "locking in" the  dollar
value  of the portfolio securities (less the amount of the premiums paid for the
options). Conversely, the Fund may  purchase call options on foreign  currencies
in  which securities it  anticipates purchasing are denominated  to secure a set
U.S. dollar price for such securities and protect against a decline in the value
of the U.S.  dollar against such  foreign currency. The  Fund may also  purchase
call and put options to close out written option positions.
 
    The  Fund may also write call options on foreign currency to protect against
potential declines in its portfolio securities which are denominated in  foreign
currencies.  If the  U.S. dollar  value of the  portfolio securities  falls as a
result of a decline in the exchange rate between the foreign currency in which a
security is denominated and the U.S. dollar, then a loss to the Fund  occasioned
by  such value  decline would be  ameliorated by  receipt of the  premium on the
option sold. At the  same time, however,  the Fund gives up  the benefit of  any
rise  in value of the relevant portfolio  securities above the exercise price of
the option and, in fact, only receives a benefit from the writing of the  option
to  the extent that the value of  the portfolio securities falls below the price
of the premium received. The Fund may also write options to close out long  call
option positions.
 
    The  markets in foreign  currency options are relatively  new and the Fund's
ability to establish and close out positions  on such options is subject to  the
maintenance of a liquid secondary market. Although the Fund will not purchase or
write  such options unless  and until, in  the opinion of  the management of the
Fund, the market for them has developed sufficiently to ensure that the risks in
connection with such options are not  greater than the risks in connection  with
the  underlying  currency, there  can be  no assurance  that a  liquid secondary
market will exist  for a particular  option at any  specific time. In  addition,
options  on  foreign  currencies are  affected  by  all of  those  factors which
influence foreign exchange rates and investments generally.
 
    The value  of  a foreign  currency  option depends  upon  the value  of  the
underlying  currency relative to the U.S. dollar.  As a result, the price of the
option position may vary with changes in the value of either or both  currencies
and  have  no  relationship to  the  investment  merits of  a  foreign security,
including foreign securities  held in a  "hedged" investment portfolio.  Because
foreign   currency  transactions  occurring  in  the  interbank  market  involve
substantially larger  amounts than  those that  may be  involved in  the use  of
foreign currency options, investors may be disadvantaged by having to deal in an
odd  lot market (generally  consisting of transactions of  less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.
 
    There is  no  systematic reporting  of  last sale  information  for  foreign
currencies  or  any  regulatory requirement  that  quotations  available through
dealers or other market sources be firm or revised on a timely basis.  Quotation
information  available is generally representative of very large transactions in
the interbank market and  thus may not  reflect relatively smaller  transactions
(i.e.,  less than $1 million)  where rates may be  less favorable. The interbank
market in foreign currencies is a global, around-the-clock market. To the extent
that the U.S. options  markets are closed while  the markets for the  underlying
currencies  remain open, significant price and  rate movements may take place in
the underlying markets that are not reflected in the options market.
 
                                       19
<PAGE>
    OTC OPTIONS.  Exchange-listed  options are issued by  the OCC which  assures
that  all transactions  in such options  are properly executed.  OTC options are
purchased from or sold (written) to dealers or financial institutions which have
entered into direct agreements with the  Fund. With OTC options, such  variables
as  expiration date, exercise price and premium  will be agreed upon between the
Fund and the  transacting dealer, without  the intermediation of  a third  party
such as the OCC. If the transacting dealer fails to make or take delivery of the
securities  underlying an option it has written, in accordance with the terms of
that option, the Fund would lose the premium paid for the option as well as  any
anticipated  benefit  of the  transaction. The  Fund will  engage in  OTC option
transactions only with primary U.S. Government securities dealers recognized  by
the Federal Reserve Bank of New York.
 
    COVERED  CALL WRITING.  The Fund is  permitted to write covered call options
on portfolio  securities and  the U.S.  dollar and  foreign currencies,  without
limit,  in order to aid in achieving its investment objective. Generally, a call
option is "covered"  if the  Fund owns,  or has  the right  to acquire,  without
additional cash consideration (or for additional cash consideration held for the
Fund  by  its  Custodian  in  a  segregated  account)  the  underlying  security
(currency) subject to the option except that in the case of call options on U.S.
Treasury Bills, the  Fund might own  U.S. Treasury Bills  of a different  series
from  those underlying the  call option, but  with a principal  amount and value
corresponding to the exercise price  and a maturity date  no later than that  of
the  securities (currency) deliverable  under the call option.  A call option is
also covered if the  Fund holds a  call on the same  security (currency) as  the
underlying  security (currency) of the written  option, where the exercise price
of the call used for coverage is equal to or less than the exercise price of the
call written or greater than the exercise price of the call written if the  mark
to  market  difference  is  maintained  by the  Fund  in  cash,  U.S. Government
securities or  other high  grade debt  obligations  which the  Fund holds  in  a
segregated account maintained with its Custodian.
 
    The  Fund  will receive  from the  purchaser, in  return for  a call  it has
written, a "premium"; i.e., the price  of the option. Receipt of these  premiums
may  better enable  the Fund  to achieve  a greater  total return  than would be
realized from holding the underlying securities (currency) alone. Moreover,  the
income  received from the  premium will offset  a portion of  the potential loss
incurred by the  Fund if  the securities  (currency) underlying  the option  are
ultimately  sold (exchanged) by  the Fund at  a loss. The  premium received will
fluctuate with varying economic  market conditions. If the  market value of  the
portfolio  securities (or  the currencies  in which  they are  denominated) upon
which call options have been written increases, the Fund may receive less  total
return from the portion of its portfolio upon which calls have been written than
it would have had such calls not been written.
 
    As regards listed options and certain OTC options, during the option period,
the  Fund  may be  required, at  any  time, to  deliver the  underlying security
(currency) against payment  of the exercise  price on any  calls it has  written
(exercise  of  certain  listed  and  OTC  options  may  be  limited  to specific
expiration dates).  This obligation  is terminated  upon the  expiration of  the
option period or at such earlier time when the writer effects a closing purchase
transaction.  A closing  purchase transaction  is accomplished  by purchasing an
option of the same  series as the option  previously written. However, once  the
Fund  has been assigned an exercise notice, the  Fund will be unable to effect a
closing purchase transaction.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an outstanding call  option to  prevent an underlying  security (currency)  from
being  called, to permit the sale of  an underlying security (or the exchange of
the underlying currency) or to enable the  Fund to write another call option  on
the  underlying security  (currency) with either  a different  exercise price or
expiration date or  both. Also,  effecting a closing  purchase transaction  will
permit  the cash or proceeds from the  concurrent sale of any securities subject
to the option to be used for other investments by the Fund. The Fund may realize
a net gain or  loss from a closing  purchase transaction depending upon  whether
the  amount of the premium received on the  call option is more or less than the
cost of  effecting the  closing purchase  transaction. Any  loss incurred  in  a
closing  purchase transaction  may be wholly  or partially  offset by unrealized
appreciation  in  the  market  value  of  the  underlying  security  (currency).
Conversely, a gain resulting from a closing purchase transaction could be offset
in  whole  or in  part or  exceeded  by a  decline in  the  market value  of the
underlying security (currency).
 
                                       20
<PAGE>
    If a call option expires unexercised, the Fund realizes a gain in the amount
of the premium on the option less the commission paid. Such a gain, however, may
be offset  by  depreciation in  the  market  value of  the  underlying  security
(currency)  during the option  period. If a  call option is  exercised, the Fund
realizes a gain  or loss  from the sale  of the  underlying security  (currency)
equal  to the difference  between the purchase price  of the underlying security
(currency) and the  proceeds of  the sale of  the security  (currency) plus  the
premium received for on the option less the commission paid.
 
    Options  written by a Fund normally have expiration dates of from up to nine
months (equity securities) to eighteen months (fixed-income securities) from the
date written. The  exercise price of  a call option  may be below,  equal to  or
above the current market value of the underlying security (currency) at the time
the option is written. See "Risks of Options and Futures Transactions," below.
 
    COVERED  PUT WRITING.  As a writer of  a covered put option, the Fund incurs
an obligation to buy the security underlying the option from the purchase of the
put, at the option's exercise price at any time during the option period, at the
purchaser's election (certain  listed and OTC  put options written  by the  Fund
will  be  exercisable  by the  purchaser  only on  a  specific date).  A  put is
"covered" if,  at  all  times,  the Fund  maintains,  in  a  segregated  account
maintained  on  its  behalf  at  the  Fund's  Custodian,  cash,  U.S. Government
securities or other high grade  obligations in an amount  equal to at least  the
exercise  price of the option, at all times during the option period. Similarly,
a short put  position could  be covered by  the Fund  by its purchase  of a  put
option  on the same security  as the underlying security  of the written option,
where the exercise price of  the purchased option is equal  to or more than  the
exercise  price of the  put written or less  than the exercise  price of the put
written if the mark to market difference is maintained by the Fund in cash, U.S.
Government securities or other high grade debt obligations which the Fund  holds
in  a segregated account maintained at its  Custodian. In writing puts, the Fund
assumes the risk  of loss  should the market  value of  the underlying  security
decline  below the exercise price of the option (any loss being decreased by the
receipt of the premium on  the option written). In  the case of listed  options,
during the option period, the Fund may be required, at any time, to make payment
of the exercise price against delivery of the underlying security. The operation
of  and limitations on  covered put options in  other respects are substantially
identical to those of call options.
 
    The Fund will write put options for two purposes: (1) to receive the  income
derived  from  the premiums  paid  by purchasers;  and  (2) when  the Investment
Manager wishes to purchase the security  underlying the option at a price  lower
than its current market price, in which case it will write the covered put at an
exercise price reflecting the lower purchase price sought. The potential gain on
a  covered put option is limited to the premium received on the option (less the
commissions paid  on  the  transaction)  while the  potential  loss  equals  the
difference between the exercise price of the option and the current market price
of  the underlying securities when  the put is exercised,  offset by the premium
received (less the commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC  call
and  put options in amounts equalling up to 5% of its total assets. The Fund may
purchase call  options  in order  to  close out  a  covered call  position  (see
"Covered Call Writing" above) or purchase call options on securities they intend
to  purchase. The Fund  may also purchase  a call option  on foreign currency to
hedge against  an  adverse exchange  rate  move of  the  currency in  which  the
security  it  anticipates purchasing  is denominated  vis-a-vis the  currency in
which the exercise  price is  denominated. The purchase  of the  call option  to
effect  a closing transaction or a call written over-the-counter may be a listed
or an OTC option. In either case, the call purchased is likely to be on the same
securities (currencies)  and have  the  same terms  as  the written  option.  If
purchased  over-the-counter,  the option  would generally  be acquired  from the
dealer or financial institution which purchased the call written by the Fund.
 
    The Fund may purchase  put options on securities  (currency) which it  holds
(or  has the right to acquire) in its portfolio only to protect itself against a
decline in the value of the security (currency). If the value of the  underlying
security  (currency) were to fall below the  exercise price of the put purchased
in an amount greater than the premium paid for the option, the Fund would  incur
no  additional loss. The Fund may also purchase put options to close out written
put positions in a manner similar to call options
 
                                       21
<PAGE>
closing purchase transactions. In addition, the Fund may sell a put option which
it has  previously purchased  prior to  the sale  of the  securities  (currency)
underlying such option. Such a sale would result in a net gain or loss depending
on  whether the amount received on the sale is more or less than the premium and
other transaction costs paid on the put  option which is sold. Any such gain  or
loss  could be offset in whole or in part by a change in the market value of the
underlying security (currency). If  a put option purchased  by the Fund  expired
without being sold or exercised, the premium would be lost.
 
    RISKS  OF OPTIONS TRANSACTIONS.  During  the option period, the covered call
writer has, in return for  the premium on the  option, given up the  opportunity
for capital appreciation above the exercise price should the market price of the
underlying  security (or the currency in  which it is denominated) increase, but
has retained  the risk  of loss  should  the price  of the  underlying  security
(currency)  decline. The covered put writer also retains the risk of loss should
the market  value  of  the  underlying security  (currency)  decline  below  the
exercise  price  of the  option less  the premium  received on  the sale  of the
option. In both cases, the  writer has no control over  the time when it may  be
required  to fulfill its  obligation as a  writer of the  option. Once an option
writer has received  an exercise  notice, it  cannot effect  a closing  purchase
transaction  in  order to  terminate its  obligation under  the option  and must
deliver or receive the underlying securities (currency) at the exercise price.
 
    Prior to exercise or expiration, an  option position can only be  terminated
by  entering into  a closing  purchase or  sale transaction.  If a  covered call
option writer is unable to effect a closing purchase transaction or to  purchase
an  offsetting over-the-counter option,  it cannot sell  the underlying security
until the option expires or the option is exercised. Accordingly, a covered call
option writer  may  not  be  able to  sell  (exchange)  an  underlying  security
(currency) at a time when it might otherwise be advantageous to do so. A covered
put  option writer who is unable to  effect a closing purchase transaction or to
purchase an offsetting over-the-counter option  would continue to bear the  risk
of  decline in the market price of  the underlying security (currency) until the
option expires  or is  exercised. In  addition, a  covered put  writer would  be
unable to utilize the amount held in cash or U.S. Government or other high grade
short-term  debt obligations as security for the put option for other investment
purposes until the exercise or expiration of the option.
 
    The Fund's ability to  close out its  position as a writer  of an option  is
dependent  upon the existence of a  liquid secondary market on option Exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC options, as such options will generally only be closed out by entering  into
a closing purchase transaction with the purchasing dealer. However, the Fund may
be  able to purchase an offsetting option  which does not close out its position
as a writer but constitutes an asset of equal value to the obligation under  the
option  written. If the Fund is not able to either enter into a closing purchase
transaction or purchase an offsetting position, it will be required to  maintain
the  securities subject to the call, or  the collateral underlying the put, even
though it might not be advantageous to do so, until a closing transaction can be
entered into (or the option is exercised or expires).
 
    Among the possible reasons for the  absence of a liquid secondary market  on
an  Exchange are:  (i) insufficient  trading interest  in certain  options; (ii)
restrictions on  transactions  imposed  by an  Exchange;  (iii)  trading  halts,
suspensions  or other restrictions imposed with respect to particular classes or
series of  options or  underlying securities;  (iv) interruption  of the  normal
operations  on an Exchange; (v)  inadequacy of the facilities  of an Exchange or
the Options Clearing Corporation  ("OCC") to handle  current trading volume;  or
(vi)  a decision by one or more  Exchanges to discontinue the trading of options
(or a  particular class  or series  of options),  in which  event the  secondary
market  on that Exchange (or in that class  or series of options) would cease to
exist, although outstanding options on that Exchange that had been issued by the
OCC as  a result  of trades  on that  Exchange would  generally continue  to  be
exercisable in accordance with their terms.
 
    Exchanges  limit the amount by which the price of a future contract may move
on any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased. In the event of adverse price movements, the Fund would continue to
be required to  make daily  cash payments of  variation margin  on open  futures
 
                                       22
<PAGE>
positions. In such situations, if the Fund has insufficient cash, it may have to
sell  portfolio securities to meet daily variation margin requirements at a time
when it may be disadvantageous to do  so. In addition, the Fund may be  required
to  take or  make delivery of  the instruments underlying  interest rate futures
contracts it holds at a time when it is disadvantageous to do so. The  inability
to  close out options and futures positions could also have an adverse impact on
the Fund's ability to effectively hedge its portfolio.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in options, futures or  options thereon, the Fund could  experience
delays and/or losses in liquidating open positions purchased or sold through the
broker  and/or incur  a loss  of all  or part  of its  margin deposits  with the
broker. Similarly, in the event of the bankruptcy of the writer of an OTC option
purchased by the Fund, the  Fund could experience a loss  of all or part of  the
value of the option. Transactions are entered into by the Fund only with brokers
or financial institutions deemed creditworthy by the Investment Manager.
 
    Each  of  the Exchanges  has established  limitations governing  the maximum
number of  call  or put  options  on the  same  underlying security  or  futures
contract  (whether or not  covered) which may  be written by  a single investor,
whether acting  alone or  in concert  with others  (regardless of  whether  such
options are written on the same or different Exchanges or are held or written on
one  or more accounts or through one or more brokers). An Exchange may order the
liquidation of positions found  to be in  violation of these  limits and it  may
impose  other sanctions or restrictions. These  position limits may restrict the
number of listed options which the Fund may write.
 
    While the futures contracts and options transactions to be engaged in by the
Fund for  the  purpose  of  hedging the  Fund's  portfolio  securities  are  not
speculative  in nature, there are risks inherent in the use of such instruments.
One such risk which may arise in employing futures contracts to protect  against
the  price volatility of  portfolio securities is that  the prices of securities
and indexes  subject to  futures  contracts (and  thereby the  futures  contract
prices)  may correlate imperfectly with  the behavior of the  cash prices of the
Fund's portfolio securities. Another such risk  is that prices of interest  rate
futures contracts may not move in tandem with the changes in prevailing interest
rates  against which the Fund seeks a hedge. A correlation may also be distorted
by the fact that the futures  market is dominated by short-term traders  seeking
to profit from the difference between a contract or security price objective and
their  cost of  borrowed funds. Such  distortions are generally  minor and would
diminish as the contract approached maturity.
 
    The hours of trading for options may  not conform to the hours during  which
the  underlying securities  are traded.  To the  extent that  the option markets
close before the markets  for the underlying  securities, significant price  and
rate movements can take place in the underlying markets that cannot be reflected
in the option markets.
 
    FUTURES  CONTRACTS.  The Fund may purchase  and sell interest rate and index
futures contracts  ("futures contracts")  that are  traded on  U.S. and  foreign
commodity  exchanges on such underlying securities as U.S. Treasury bonds, notes
and bills ("interest rate" figures), on the U.S. dollar and foreign  currencies,
and  such indexes as the S&P  500 Index, Moody's Investment-Grade Corporate Bond
Index and the New York Stock Exchange Composite Index ("index" futures).
 
    As a  futures contract  purchaser, the  Fund incurs  an obligation  to  take
delivery  of a specified amount  of the obligation underlying  the contract at a
specified time in the  future for a  specified price. As a  seller of a  futures
contract,  the Fund incurs an obligation to  deliver the specified amount of the
underlying obligation at a specified time in return for an agreed upon price.
 
    The Fund will  purchase or  sell interest  rate futures  contracts and  bond
index  futures contracts for  the purpose of  hedging its fixed-income portfolio
(or anticipated  portfolio) securities  against changes  in prevailing  interest
rates.  If the Investment Manager anticipates  that interest rates may rise and,
concomitantly, the price of fixed-income securities  fall, the Fund may sell  an
interest  rate futures contract  or a bond index  futures contract. If declining
interest rates are anticipated, the Fund  may purchase an interest rate  futures
contract to protect against a potential increase in the price of U.S. Government
securities the
 
                                       23
<PAGE>
Fund  intends to purchase. Subsequently, appropriate fixed-income securities may
be purchased by  the Fund in  an orderly fashion;  as securities are  purchased,
corresponding  futures  positions would  be  terminated by  offsetting  sales of
contracts.
 
    The Fund will purchase or sell futures  contracts on the U.S. dollar and  on
foreign  currencies to hedge against an anticipated rise or decline in the value
of the U.S. dollar or foreign currency in which a portfolio security of the Fund
is denominated vis-a-vis another currency.
 
    The Fund will purchase  or sell index futures  contracts for the purpose  of
hedging  its portfolio (or anticipated  portfolio) securities against changes in
their  prices.  If  the  Investment  Manager  anticipates  that  the  prices  of
securities  held by the  Fund may fall,  the Fund may  sell an appropriate index
futures contract. Conversely, if the Investment Manager wishes to hedge  against
anticipated  price rises in those securities which the Fund intends to purchase,
the Fund may purchase an index futures contracts. In addition, interest rate and
index futures contracts will be bought or sold in order to close out a short  or
long position in a corresponding futures contract.
 
    Although  most interest rate  futures contracts call  for actual delivery or
acceptance of  securities,  the contracts  usually  are closed  out  before  the
settlement  date  without  the  making  or  taking  of  delivery.  Index futures
contracts provide for the  delivery of an  amount of cash  equal to a  specified
dollar  amount times the difference between the stock index value at the open or
close of the last trading day of the contract and the futures contract price.  A
futures contract sale is closed out by effecting a futures contract purchase for
the  same aggregate amount of the specific  type of equity security and the same
delivery date. If  the sale  price exceeds  the offsetting  purchase price,  the
seller  would be paid the difference and would realize a gain. If the offsetting
purchase price exceeds the sale price,  the seller would pay the difference  and
would  realize a loss. Similarly,  a futures contract purchase  is closed out by
effecting a futures contract sale for the same aggregate amount of the  specific
type of equity security and the same delivery date. If the offsetting sale price
exceeds  the purchase price, the purchaser would  realize a gain, whereas if the
purchase price exceeds the offsetting sale price, the purchaser would realize  a
loss.  There is no assurance that the Fund  will be able to enter into a closing
transaction.
 
    INTEREST RATE FUTURES CONTRACTS.  When the Fund enters into an interest rate
futures contract, it is initially required to deposit with the Fund's Custodian,
in a segregated account in the name of the broker performing the transaction, an
"initial margin"  of cash  or U.S.  Government securities  or other  high  grade
short-term  debt obligations equal  to approximately 2%  of the contract amount.
Initial margin requirements are  established by the  Exchanges on which  futures
contracts  trade and may,  from time to  time, change. In  addition, brokers may
establish margin  deposit  requirements  in  excess of  those  required  by  the
Exchanges.
 
    Initial   margin  in  futures  transactions  is  different  from  margin  in
securities transactions in that initial margin does not involve the borrowing of
funds by a brokers' client but is,  rather, a good faith deposit on the  futures
contract  which will be returned to the  Fund upon the proper termination of the
futures contract. The margin  deposits made are marked  to market daily and  the
Fund may be required to make subsequent deposits called "variation margin", with
the  Fund's  Custodian, in  the account  in the  name of  the broker,  which are
reflective of price  fluctuations in the  futures contract. Currently,  interest
rates  futures  contracts  can be  purchased  on  debt securities  such  as U.S.
Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6 1/2  and
10 years, GNMA Certificates and Bank Certificates of Deposit.
 
    INDEX FUTURES CONTRACTS.  The Fund may invest in index futures contracts. An
index  futures contract sale  creates an obligation  by the Fund,  as seller, to
deliver cash at  a specified  future time.  An index  futures contract  purchase
would  create an obligation by the Fund,  as purchaser, to take delivery of cash
at a specified  future time.  Futures contracts on  indexes do  not require  the
physical  delivery of securities, but provide for a final cash settlement on the
expiration date  which  reflects  accumulated profits  and  losses  credited  or
debited to each party's account.
 
    The  Fund  is  required to  maintain  margin deposits  with  brokerage firms
through which it  effects index futures  contracts in a  manner similar to  that
described    above   for    interest   rate    futures   contracts.   Currently,
 
                                       24
<PAGE>
the initial margin requirement  is approximately 5% of  the contract amount  for
index  futures. In addition, due to  current industry practice, daily variations
in gains and losses on  open contracts are required to  be reflected in cash  in
the  form  of  variation margin  payments.  The  Fund may  be  required  to make
additional margin payments during the term of the contract.
 
    At any time prior to expiration of the futures contract, the Fund may  elect
to  close the  position by  taking an  opposite position  which will  operate to
terminate the Fund's position in the futures contract. A final determination  of
variation  margin is  then made, additional  cash is  required to be  paid by or
released to the Fund and the Fund realizes a loss or a gain.
 
    Currently, index futures contracts can be purchased or sold with respect to,
among others, the Standard  & Poor's 500  Stock Price Index  and the Standard  &
Poor's  100 Stock Price Index  on the Chicago Mercantile  Exchange, the New York
Stock Exchange  Composite Index  on the  New York  Futures Exchange,  the  Major
Market  Index  on  the  American Stock  Exchange,  the  Moody's Investment-Grade
Corporate Bond Index  on the Chicago  Board of  Trade and the  Value Line  Stock
Index on the Kansas City Board of Trade.
 
    OPTIONS  ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts and enter into closing transactions with respect to
such options to terminate an existing position. An option on a futures  contract
gives  the purchaser the right (in return  for the premium paid), and the writer
the obligation, to assume a position in  a futures contract (a long position  if
the option is a call and a short position if the option is a put) at a specified
exercise  price at any time during the term  of the option. Upon exercise of the
option, the delivery of the futures position by the writer of the option to  the
holder  of the option is  accompanied by delivery of  the accumulated balance in
the writer's futures margin  account, which represents the  amount by which  the
market  price of the  futures contract at  the time of  exercise exceeds, in the
case of a call, or is less than, in the case of a put, the exercise price of the
option on the futures contract.
 
    The Fund will purchase and write options on futures contracts for  identical
purposes  to  those set  forth  above for  the  purchase of  a  futures contract
(purchase of a call option or  sale of a put option)  and the sale of a  futures
contract  (purchase of a put option or sale of a call option), or to close out a
long or short  position in futures  contracts. If, for  example, the  Investment
Manager  wished  to  protect  against  an increase  in  interest  rates  and the
resulting negative  impact  on  the  value of  a  portion  of  its  fixed-income
portfolio,  it might write a  call option on an  interest rate futures contract,
the underlying security of  which correlates with the  portion of the  portfolio
the  Investment Manager seeks to hedge. Any  premiums received in the writing of
options on futures  contracts may, of  course, augment the  total return of  the
Fund  and thereby  provide a further  hedge against losses  resulting from price
declines in portions of the Fund's portfolio.
 
    The writer of an option on a futures contract is required to deposit initial
and variation margin  pursuant to  requirements similar to  those applicable  to
futures  contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.
 
    LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS  ON FUTURES.  The Fund may  not
enter into futures contracts or purchase related options thereon if, immediately
thereafter, the amount committed to margin plus the amount paid for premiums for
unexpired  options on futures  contracts exceeds 5%  of the value  of the Fund's
total assets, after taking into  account unrealized gains and unrealized  losses
on such contracts it has entered into, provided, however, that in the case of an
option that is in-the-money (the exercise price of the call (put) option is less
(more)  than  the  market price  of  the  underlying security)  at  the  time of
purchase, the  in-the-money  amount  may  be excluded  in  calculating  the  5%.
However,  there is no overall limitation on  the percentage of the Fund's assets
which may be subject to  a hedge position. In  addition, in accordance with  the
regulations of the Commodity Futures Trading Commission ("CFTC") under which the
Fund  is exempted from registration  as a commodity pool  operator, the Fund may
only enter into futures contracts and options on futures contracts  transactions
for  purposes of hedging a part or all of its portfolio. If the CFTC changes its
regulations so that  the Fund  would be permitted  to write  options on  futures
contracts  for purposes other  than hedging the  Fund's investments without CFTC
 
                                       25
<PAGE>
registration,  the  Fund may  engage in  such  transactions for  those purposes.
Except as described above, there are no other limitations on the use of  futures
and options thereon by the Fund.
 
    RISKS  OF TRANSACTIONS IN  FUTURES CONTRACTS AND RELATED  OPTIONS.  The Fund
may sell a  futures contract  to protect  against the  decline in  the value  of
securities held by the Fund. However, it is possible that the futures market may
advance  and the value of  the securities held in the  portfolio of the Fund may
decline. If this occurred, the Fund would lose money on the futures contract and
also experience a decline in value  of its portfolio securities. However,  while
this  could occur for a very  brief period or to a  very small degree, over time
the value of a diversified portfolio will tend to move in the same direction  as
the futures contracts.
 
    If  the Fund purchases a  futures contract to hedge  against the increase in
value of  securities  it  intends to  buy,  and  the value  of  such  securities
decreases,  then  the Fund  may determine  not  to invest  in the  securities as
planned and will realize a loss on the futures contract that is not offset by  a
reduction in the price of the securities.
 
    In  addition, if the Fund holds a long position in a futures contract or has
sold a put  option on a  futures contract,  it will hold  cash, U.S.  Government
securities  or other high grade debt obligations  equal to the purchase price of
the contract or the exercise price of the put option (less the amount of initial
or variation margin on deposit) in a segregated account maintained for the  Fund
by  its  Custodian. Alternatively,  the Fund  could cover  its long  position by
purchasing a put option on the same  futures contract with an exercise price  as
high or higher than the price of the contract held by the Fund.
 
    If  the Fund maintains a short position in  a futures contract or has sold a
call option on a futures contract, it will cover this position by holding, in  a
segregated account maintained at its Custodian, cash, U.S. Government securities
or  other high grade debt obligations equal  in value (when added to any initial
or variation margin on deposit) to the market value of the securities underlying
the futures contract or the  exercise price of the  option. Such a position  may
also be covered by owning the securities underlying the futures contract (in the
case  of a stock index futures  contract a portfolio of securities substantially
replicating the relevant index), or by holding a call option permitting the Fund
to purchase the same contract at a price  no higher than the price at which  the
short position was established.
 
    Exchanges  may limit the amount by which  the price of futures contracts may
move on any day. If  the price moves equal the  daily limit on successive  days,
then  it may prove  impossible to liquidate  a futures position  until the daily
limit moves have ceased.
 
    The extent to which the Fund  may enter into transactions involving  options
and   futures  contracts  may   be  limited  by   the  Code's  requirements  for
qualification as  a regulated  investment company  and the  Fund's intention  to
qualify  as such. See "Dividends, Distributions and Taxes" in the Prospectus and
the Statement of Additional Information.
 
    There may  exist an  imperfect correlation  between the  price movements  of
futures  contracts purchased by the Fund and  the movements in the prices of the
securities which are the  subject of the hedge.  If participants in the  futures
market elect to close out their contracts through offsetting transactions rather
than  meet margin deposit  requirements, distortions in  the normal relationship
between the debt securities and futures markets could result. Price  distortions
could also result if investors in futures contracts opt to make or take delivery
of  underlying securities rather than engage  in closing transactions due to the
resultant reduction in the liquidity of the futures market. In addition, due  to
the  fact that, from the point of  view of speculators, the deposit requirements
in the futures  markets are less  onerous than margin  requirements in the  cash
market, increased participation by speculators in the futures market could cause
temporary  price distortions. Due to the possibility of price distortions in the
futures market and because of the imperfect correlation between movements in the
prices of securities and movements in the prices of futures contracts, a correct
forecast of interest rate trends by the Investment Manager may still not  result
in a successful hedging transaction.
 
    There  is no assurance that a liquid secondary market will exist for futures
contracts and related  options in  which the  Fund may  invest. In  the event  a
liquid market does not exist, it may not be possible
 
                                       26
<PAGE>
to  close out a futures  position, and in the  event of adverse price movements,
the Fund would continue to be required to make daily cash payments of  variation
margin.  In addition, limitations  imposed by an  exchange or board  of trade on
which futures contracts are traded may  compel or prevent the Fund from  closing
out  a contract which may result in reduced  gain or increased loss to the Fund.
The absence of a liquid market in futures contracts might cause the Fund to make
or take  delivery  of  the underlying  securities  at  a time  when  it  may  be
disadvantageous to do so.
 
    Compared  to the purchase or sale of futures contracts, the purchase of call
or put options  on futures contracts  involves less potential  risk to the  Fund
because  the maximum amount  at risk is  the premium paid  for the options (plus
transaction costs). However, there may be  circumstances when the purchase of  a
call  or put option  on a futures  contract would result  in a loss  to the Fund
notwithstanding that the purchase or sale of a futures contract would not result
in a loss, as in the  instance where there is no  movement in the prices of  the
futures contract or underlying securities.
 
    The  Investment  Manager  has  substantial  experience  in  the  use  of the
investment techniques described  above under  the heading  "Options and  Futures
Transactions,"  which techniques require  skills different from  those needed to
select  the  portfolio  securities   underlying  various  options  and   futures
contracts.
 
PORTFOLIO TURNOVER
 
    It  is anticipated that  the Fund's portfolio turnover  rate will not exceed
100%. A 100% turnover rate would occur,  for example, if 100% of the  securities
held  in  the Fund's  portfolio (excluding  all  securities whose  maturities at
acquisition were one year or less) were sold and replaced within one year.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment  restrictions  listed  below  have  been  adopted  by  the  fund   as
fundamental   policies,  except  as  otherwise   indicated.  Under  the  Act,  a
fundamental policy may  not be changed  without the  vote of a  majority of  the
outstanding  voting  securities of  the  fund, as  defined  in the  Act.  Such a
majority is defined as the lesser of (a) 67% or more of the shares present at  a
meeting  of shareholders, if the holders of 50% of the outstanding shares of the
Fund are present or represented by proxy or (b) more than 50% of the outstanding
shares of the Fund.
 
    The Fund may not:
 
        1.  Purchase or sell real estate or interests therein, although the fund
    may purchase securities of  issuers which engage  in real estate  operations
    and securities secured by real estate or interests therein.
 
        2.    Purchase  oil, gas  or  other  mineral leases,  rights  or royalty
    contracts or exploration or development  programs, except that the Fund  may
    invest  in the securities of companies  which operate, invest in, or sponsor
    such programs.
 
        3.   With the  exception  of reverse  repurchase agreements  and  dollar
    rolls,  borrow  money, except  that  the Fund  may  borrow from  a  bank for
    temporary or emergency purposes  in amounts not exceeding  5% (taken at  the
    lower  of cost  or current  value) of  its total  assets (not  including the
    amount borrowed).
 
        4.  Pledge  its assets or  assign or otherwise  encumber them except  to
    secure  borrowings effected within the  limitations set forth in restriction
    (3). For  the  purpose of  this  restriction, collateral  arrangements  with
    respect  to the writing of options  and collateral arrangements with respect
    to initial or variation margin for futures  are not deemed to be pledges  of
    assets.
 
        5.  Issue senior securities as defined in the Act, except insofar as the
    Fund  may  be deemed  to  have issued  a senior  security  by reason  of (a)
    entering into any repurchase or reverse repurchase agreement or dollar roll;
    (b) purchasing any securities  on a when-issued  or delayed delivery  basis;
 
                                       27
<PAGE>
    (c)  purchasing  or  selling  futures  contracts,  forward  foreign exchange
    contracts or options;  (d) borrowing money  in accordance with  restrictions
    described above; or (e) lending portfolio securities.
 
        6.   Make loans of  money or securities, except:  (a) by the purchase of
    publicly  distributed  debt  obligations  in  which  the  Fund  may   invest
    consistent  with its investment objective and policies; (b) by investment in
    repurchase agreements; or (c) by lending its portfolio securities.
 
        7.  Make short sales of securities.
 
        8.  Purchase securities on margin,  except for such short-term loans  as
    are  necessary for  the clearance  of portfolio  securities. The  deposit or
    payment by  the Fund  of  initial or  variation  margin in  connection  with
    futures  contracts or related options thereon is not considered the purchase
    of a security on margin.
 
        9.  Engage in the underwriting of securities, except insofar as the Fund
    may be deemed an underwriter under  the Securities Act of 1933 in  disposing
    of a portfolio security.
 
        10. Invest for purposes of exercising control or management of any other
    issuer.
 
        11.  Purchase  securities  of  other  investment  companies,  except  in
    connection with a  merger, consolidation, reorganization  or acquisition  of
    assets  or in accordance with the provisions of Section 12(d) of the Act and
    any Rules promulgated thereunder.
 
        12. Purchase or  sell commodities or  commodities contracts except  that
    the Fund may purchase or sell futures contracts or options on futures.
 
    In  addition,  as  a  nonfundamental  policy, the  Fund  may  not  invest in
securities of  any issuer  if, to  the knowledge  of the  Fund, any  officer  or
trustee  of the Fund or  any officer or director  of the Investment Manager owns
more than 1/2  of 1%  of the  outstanding securities  of such  issuer, and  such
officers,  trustees  and  directors who  own  more than  1/2  of 1%  own  in the
aggregate more than 5% of the outstanding securities of such issuers.
 
    If a percentage restriction is adhered to at the time of investment, a later
increase or  decrease  in  percentage  resulting from  a  change  in  values  of
portfolio  securities or amount of total or  net assets will not be considered a
violation of any of the foregoing restrictions.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
   
    The Investment  Manager  is  responsible  for  decisions  to  buy  and  sell
securities and commodities for the Fund, the selection of brokers and dealers to
effect  the transactions, and the negotiation  of brokerage commissions, if any.
The Fund expects that the primary market for the securities in which it  intends
to  invest  will  generally  be  the  over-the-counter  market.  Securities  are
generally traded in the  over-the-counter market on a  "net" basis with  dealers
acting as principal for their own accounts without charging a stated commission,
although  the price  of the  security usually includes  a profit  to the dealer.
Options and futures transactions will usually be effected through a broker and a
commission will  be charged.  The  Fund also  expects  that securities  will  be
purchased  at times in  underwritten offerings where the  price includes a fixed
amount of compensation, generally referred to as the underwriter's concession or
discount.  On  occasion,  the  Fund  may  also  purchase  certain  money  market
instruments  directly from an issuer, in  which case no commissions or discounts
are paid. The Fund  paid no brokerage commissions  during the fiscal year  ended
April 30, 1996.
    
 
   
    The Investment Manager currently serves as investment manager to a number of
clients,  including other  investment companies,  and may  in the  future act as
investment manager or adviser  to others. It is  the practice of the  Investment
Manager  to cause purchase and sale transactions  to be allocated among the Fund
and others whose  assets it manages  in such  manner as it  deems equitable.  In
making  such  allocations  among the  Fund  and other  client  accounts, various
factors may be considered, including  the respective investment objectives,  the
relative    size   of   portfolio   holdings   of   the   same   or   comparable
    
 
                                       28
<PAGE>
   
securities, the  availability of  cash for  investment, the  size of  investment
commitments  generally  held  and the  opinion  of the  persons  responsible for
managing the portfolios of the  Fund and other client  accounts. In the case  of
certain  initial and secondary  offerings, the Investment  Manager may utilize a
pro-rata allocation process based on the size of the Dean Witter Funds  involved
and the number of shares available from the public offering.
    
 
    The  policy of the Fund, regarding purchases and sales of securities is that
primary consideration  be  given to  obtaining  the most  favorable  prices  and
efficient  execution  of  transactions.  In  seeking  to  implement  the  Fund's
policies, the Investment  Manager effects  transactions with  those brokers  and
dealers  who the Investment  Manager believes provide  the most favorable prices
and are capable  of providing  efficient executions. If  the Investment  Manager
believes  such price and executions are obtainable  from more than one broker or
dealer, it may give consideration  to placing portfolio transactions with  those
brokers  and dealers who also furnish research and other services to the Fund or
the Investment Manager. Although the  Fund may purchase securities from  brokers
or  dealers acting as principal,  who also provide research  for the advisor, it
will not pay  a mark-up in  consideration for such  services. Such services  may
include,  but are not limited to, any  one or more of the following: information
as to  the availability  of  securities for  purchase  or sale;  statistical  or
factual  information or  opinions pertaining  to investment;  wire services; and
appraisals or evaluations of portfolio securities.
 
    The information and services received by the Investment Manager from brokers
and dealers may be  of benefit to  the Investment Manager  in the management  of
accounts  of some of its  other clients and may not,  in every case, benefit the
Fund directly. While the receipt of  such information and services is useful  in
varying  degrees and would  generally reduce the amount  of research or services
otherwise performed by the Investment  Manager and thereby reduce its  expenses,
it is of indeterminable value and the Fund will not reduce the management fee it
pays  to the Investment  Manager by any  amount that may  be attributable to the
value of such services.
 
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR.  The
Fund  will limit  its transactions  with DWR  to U.S.  Government and Government
Agency Securities,  Bank Money  Instruments (i.e.  Certificates of  Deposit  and
Bankers'  Acceptances) and Commercial Paper.  Such transactions will be effected
with DWR only when the  price available from DWR  is better than that  available
from other dealers.
 
    Consistent  with  the  policy  described  above,  brokerage  transactions in
securities and commodities listed on  exchanges or admitted to unlisted  trading
privileges  may be effected  through DWR. In  order for DWR  to effect portfolio
transactions for the Fund, the commissions, fees or other remuneration  received
by  DWR must be reasonable  and fair compared to  the commissions, fees or other
remuneration paid to  other brokers in  connection with comparable  transactions
involving  similar securities  being purchased or  sold on an  exchange during a
comparable period of time. This standard would allow DWR to receive no more than
the remuneration  which would  be expected  to be  received by  an  unaffiliated
broker  in a commensurate arms-length  transaction. Furthermore, the Trustees of
the Fund,  including  a  majority  of the  Trustees  who  are  not  "interested"
Trustees,  have adopted procedures which are reasonably designed to provide that
any commissions, fees or other remuneration paid to DWR are consistent with  the
foregoing standard.
 
   
    During  the fiscal year ended April 30, 1996, the Fund purchased $529,965 of
Lehman Brothers Holdings, Inc., 7.625%  bonds, maturing 7/15/97 an issuer  which
was  among  the  ten  broker-dealers with  whom  the  Fund  transacted principal
transactions in the largest amounts.  The Fund's holdings in the  aforementioned
security amounted to $1,021,290 at April 30, 1996.

PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
   
    As  discussed in the Prospectus, the Fund  offers its shares for sale to the
public  through  Dean  Witter  Distributors  Inc.  (the  "Distributor"),  on   a
continuous  basis at an  offering price equal  to the net  asset value per share
next determined following receipt of any order without a sales charge. (See  the
Prospectus--   "Purchase  of   Fund  Shares").   The  Distributor,   a  Delaware
corporation, is an indirect  wholly-owned subsidiary of  DWDC. In addition,  the
Distributor  has  entered into  selected broker-dealer  agreements with  DWR and
other dealers ("Selected Broker-Dealers") pursuant  to which shares of the  Fund
are sold. The Trustees of the Fund, including a majority of the Trustees who are
not,  and were not  at the time they  voted, interested persons  of the Fund, as
defined in the Act (the "Independent Trustees"), approved, at their meeting held
on December  2,  1993,  a  Distribution  Agreement  appointing  the  Distributor
exclusive  distributor of the Fund's shares and providing for the Distributor to
bear distribution expenses not borne by the Fund. By its terms, the Distribution
Agreement had an initial term ending April  30, 1995, and provides that it  will
continue from year to year thereafter if approved by the Board. At their meeting
held on April 17, 1996, the Trustees, including all of the Independent Trustees,
approved  the most recent continuation of the Distribution Agreement until April
30, 1997.
    
 
    The Distributor will bear  all expenses it may  incur in providing  services
under   the  Distribution  Agreement.  Such  expenses  include  the  payment  of
commissions for sales of the Fund's shares and incentive compensation to account
executives. The Distributor will  also pay certain  expenses in connection  with
the  distribution of the shares  of the Fund, including  the costs of preparing,
printing and distributing advertising or promotional materials, and the costs of
printing  and  distributing  prospectuses   and  supplements  thereto  used   in
connection  with the offering and sale of  the Fund's shares. The Fund bears the
costs of  initial typesetting,  printing and  distribution of  prospectuses  and
supplements  thereto  to shareholders.  The  Fund also  will  bear the  costs of
registering the Fund and its shares under federal and state securities laws. The
Fund and the  Distributor have agreed  to indemnify each  other against  certain
liabilities, including liabilities under the Securities Act of 1933, as amended.
Under  the  Distribution Agreement,  the Distributor  uses  its best  efforts in
rendering services to the Fund, but  in the absence of willful misfeasance,  bad
faith,   gross  negligence  or  reckless   disregard  of  its  obligations,  the
Distributor is not liable to the Fund  or any of its shareholders for any  error
of  judgment or  mistake of law  or for  any act or  omission or  for any losses
sustained by the Fund or its shareholders.
 
PLAN OF DISTRIBUTION
 
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act (the "Plan")  whereby the Distributor  or any of  its affiliates,  including
InterCapital,  is authorized to  utilize their own  resources to finance certain
activities in connection with the distribution  of shares of the Fund. The  Plan
was  approved by the Trustees and by InterCapital as the Fund's sole shareholder
on December  2, 1993,  whereupon the  Plan went  into effect.  The vote  of  the
Trustees, which was cast in person at a meeting called for the purpose of voting
on  such Plan, included a majority  of the Trustees who are  not and were not at
the time of their voting interested persons of the Fund and who have and had  at
the  time  of  their votes  no  direct  or indirect  financial  interest  in the
operation of  the  Plan (the  "Independent  12b-1 Trustees").  In  making  their
decision  to adopt  the Plan,  the Trustees  requested from  the Distributor and
received  such  information  as  they  deemed  necessary  to  make  an  informed
determination  as  to  whether or  not  adoption of  the  Plan was  in  the best
interests of  the shareholders  of  the Fund.  After  due consideration  of  the
information  received, the  Trustees, including the  Independent 12b-1 Trustees,
determined that adoption of the Plan would benefit the shareholders of the Fund.
 
    The Plan provides  that the Fund  authorizes the Distributor  or any of  its
affiliates,  including InterCapital, to bear the  expense of all promotional and
distribution related activities on behalf of the Fund. Among the activities  and
services  which may  be provided  under the  Plan are:  (1) compensation  to and
expenses of account executives and other employees of the Distributor and  other
Selected  Broker-Dealers 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
 
                                       30
<PAGE>
distributing  sales literature;  and (5)  providing advertising  and promotional
activities, including direct mail solicitation and television, radio, newspaper,
magazine and other media advertisements.
 
    Pursuant to the  Selected Broker-Dealer Agreements  between the  Distributor
and  DWR and  other Selected Broker-Dealers,  the account executives  of DWR and
other Selected Broker-Dealers may be paid  an annual fee based upon the  current
value  of the respective accounts  for which they are  the account executives of
record. The fee also  reflects a payment made  for expenses associated with  the
servicing  of shareholder's accounts, including the expenses of operating branch
offices in  connection  with  the servicing  of  shareholder's  accounts,  which
expenses  include lease costs, the salaries  and employee benefits of operations
and sales support personnel, utility  costs, communications costs and the  costs
of  stationery  and  supplies  and  other  expenses  relating  to  branch office
servicing of shareholder accounts.
 
    Under the Plan, the Distributor uses its best efforts in rendering  services
to  the  Fund, but  in  the absence  of  willful misfeasance,  bad  faith, gross
negligence or  reckless disregard  of its  obligations, the  Distributor is  not
liable  to the  Fund or  any of its  shareholders for  any error  of judgment or
mistake of law or  for any act or  omission or for any  losses sustained by  the
Fund or its shareholders.
 
    Under  the  Plan,  the Distributor  provides  the  Fund, for  review  by the
Trustees, and  the  Trustees review,  promptly  after  the end  of  each  fiscal
quarter,  a written report  regarding the distribution  expenses incurred by the
Distributor of the Fund during such fiscal quarter, which report includes (1) an
itemization of the types of expenses and the purposes therefor; (2) the  amounts
of  such expenses; and (3) a description of the benefits derived by the Fund. In
the Trustees' quarterly  review of  the Plan  they will  consider its  continued
appropriateness.
 
   
    The  Plan had  an initial  term ending  April 30,  1995, and  will remain in
effect from  year to  year  thereafter, provided  such continuance  is  approved
annually  by a  vote of  the Trustees, including  a majority  of the Independent
12b-1 Trustees. Assumption by  the Fund of any  distribution expenses under  the
Plan  must be approved by  the shareholders, and all  material amendments to the
Plan must be approved by  the Trustees in the  manner described above. The  Plan
may  be terminated at any  time, without payment of any  penalty, by vote of the
holders of  a majority  of the  Independent 12b-1  Trustees or  by a  vote of  a
majority  of the outstanding  voting securities (as  defined in the  Act) on not
more than 30 days written notice to any other party to the Plan. So long as  the
Plan is in effect, the selection or nomination of the Independent 12b-1 Trustees
is  committed  to the  discretion of  the Independent  12b-1 Trustees.  At their
meeting held on April 17, 1996, the  Trustees of the Fund, including all of  the
Independent 12b-1 Trustees, approved the most recent continuance of the Plan for
an additional year until April 30, 1997.
    
 
    No  interested person of the Fund nor any  Trustee of the Fund who is not an
interested person of the Fund, as defined in the Act, has any direct or indirect
financial interest in the operation  of the Plan except  to the extent that  the
Distributor  or certain of its employees may  be deemed to have such an interest
as a result of benefits derived from the successful operation of the Plan or  as
a  result  of receiving  a portion  of  the amounts  expended thereunder  by the
Distributor or any of its affiliates, including InterCapital.
 
DETERMINATION OF NET ASSET VALUE
 
    As stated in the Prospectus, short-term securities with remaining maturities
of sixty days  or less at  the time of  purchase are valued  at amortized  cost,
unless  the  Trustees determine  such does  not  reflect the  securities' market
value, in which  case these securities  will be  valued at their  fair value  as
determined by the Trustees. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach a remaining maturity of sixty
days,  whereupon they will be valued at  amortized cost using their value on the
61st day unless  the Trustees determine  such does not  reflect the  securities'
market  value, in which case these securities will be valued at their fair value
as determined by the Trustees. All other securities and other assets are  valued
at  their fair value as determined in good faith under procedures established by
and under the supervision of the Trustees.
 
                                       31
<PAGE>
    As discussed in the Prospectus, the net asset value per share of the Fund is
determined once daily on each day that the New York Stock Exchange is open.  The
net asset value per share will not be determined on such federal and non-federal
holidays  as are  observed by the  New York  Stock Exchange. The  New York Stock
Exchange currently observes the following holidays: New Year's Day;  Presidents'
Day;  Good Friday; Memorial Day; Independence  Day; Labor Day; Thanksgiving Day;
and Christmas Day.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened for the investor on  the books of the Fund  and maintained by the  Fund's
Transfer  Agent, Dean  Witter Trust Company  (the "Transfer Agent").  This is an
open account in which shares owned by the investor are credited by the  Transfer
Agent  in lieu  of issuance of  a share  certificate. If a  share certificate is
desired, it must be requested in writing for each transaction. Certificates  are
issued  only for full shares and may be  redeposited in the account at any time.
There is no charge  to the investor  for issuance of  a certificate. Whenever  a
shareholder  instituted transaction  takes place  in the  Shareholder Investment
Account, the shareholder will be mailed  a confirmation of the transaction  from
the Fund or from DWR or other selected broker-dealer.
 
    INVESTMENT  OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  As discussed in
the Prospectus,  any shareholder  who  receives a  cash payment  representing  a
dividend  or capital gains distribution may invest such dividend or distribution
at net asset  value (without  sales charge),  next determined  by returning  the
check  or the proceeds  to the Transfer  Agent within 30  days after the payment
date. If the  shareholder returns the  proceeds of a  dividend or  distribution,
such  funds  must  be accompanied  by  a  signed statement  indicating  that the
proceeds constitute a dividend or  distribution to be invested. Such  investment
will  be made at the net asset value  per share next determined after receipt of
the check or proceeds by the Transfer Agent.
 
    AUTOMATIC INVESTMENT  OF DIVIDENDS  AND  DISTRIBUTIONS.   As stated  in  the
Prospectus,   all  income   dividends  and   capital  gains   distributions  are
automatically paid  in  full and  fractional  shares  of the  Fund,  unless  the
shareholder  requests that they be paid in  cash. Each purchase of shares of the
Fund is made upon the condition that the Transfer Agent is thereby automatically
appointed as agent of  the investor to receive  all dividends and capital  gains
distributions  on shares owned by the investor. Such dividends and distributions
will be paid, at  the net asset value  per share, in shares  of the Fund (or  in
cash  if the shareholder so requests) on the monthly payment date, which will be
no later than  the last  business day  of the month  for which  the dividend  or
distribution  is  payable.  Processing  of  dividend  checks  begins immediately
following the monthly payment date.  Shareholders who have requested to  receive
dividends  in cash will normally receive their monthly dividend check during the
first ten days of the following month.  At any time an investor may request  the
Transfer  Agent, in writing,  to have subsequent  dividends and/or capital gains
distributions paid  to  him  or  her  in cash  rather  than  shares.  To  assure
sufficient  time to process the  change, such request should  be received by the
Transfer Agent at  least five  business days  prior to  the record  date of  the
dividend  or distribution.  In the case  of recently purchased  shares for which
registration instructions  have  not been  received  on the  record  date,  cash
payments  will  be made  to DWR  or  other selected  broker-dealer, and  will be
forwarded to the shareholder, upon the receipt of proper instructions.
 
    TARGETED  DIVIDENDS.-SM-    In  states  where  it  is  legally  permissible,
shareholders  may also have all income dividends and capital gains distributions
automatically invested in shares of an open-end Dean Witter Fund other than Dean
Witter Short-Term Bond Fund. Such investment will be made as described above for
automatic investment in shares of the Fund, at the net asset value per share  of
the selected Dean Witter Fund as of the close of business on the payment date of
the  dividend or distribution and  will begin to earn  dividends, if any, in the
selected Dean Witter Fund the next business day. To participate in the  Targeted
Dividends  program,  shareholders should  contact  their DWR  or  other selected
broker-dealer account executive or the Transfer Agent. Shareholders of the  Fund
must be shareholders of the Dean
 
                                       32
<PAGE>
Witter  Fund targeted  to receive  investments from  dividends at  the time they
enter the Targeted Dividends program. Investors should review the prospectus  of
the targeted Dean Witter Fund before entering the program.
 
    EASYINVEST.-SM-    Shareholders may  subscribe  to EasyInvest,  an automatic
purchase plan  which  provides  for  any  amount  from  $100  to  $5,000  to  be
transferred automatically from a checking or savings account, on a semi-monthly,
monthly  or quarterly basis, to  the Transfer Agent for  investment in shares of
the Fund. Shares purchased through EasyInvest will be added to the shareholder's
existing account at  the net asset  value calculated the  same business day  the
transfer  of  funds is  effected.  For further  information  or to  subscribe to
EasyInvest,  shareholders   should  contact   their   DWR  or   other   selected
broker-dealer account executive or the Transfer Agent.
 
    SYSTEMATIC  WITHDRAWAL PLAN.   As discussed in  the Prospectus, a 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 offering price. The  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.
 
    Withdrawal  Plan payments should  not be considered  as dividends, yields or
income. If periodic withdrawal plan payments continuously exceed net  investment
income  and net  capital gains,  the shareholder's  original investment  will be
correspondingly reduced and ultimately exhausted.
 
    Each withdrawal constitutes  a redemption  of shares  and any  gain or  loss
realized  must be recognized for federal  income, and generally, state and local
tax purposes.
 
    Dividends  and  capital  gains  distributions  on  shares  held  under   the
Systematic  Withdrawal Plan will  be invested in  additional full and fractional
shares at net asset value (without a  sales charge). Shares will be credited  to
an  open account for the  investor by the Transfer  Agent; no share certificates
will be issued. Only shareholders having accounts in which no share certificates
have been  issued  will  be  permitted  to enroll  in  the  Withdrawal  Plan.  A
shareholder  is  entitled to  a share  certificate upon  written request  to the
Transfer Agent, although in that  event the shareholder's Systematic  Withdrawal
Plan will be terminated.
 
    The  Transfer Agent acts  as agent for  the shareholder in  tendering to the
Fund for redemption sufficient full and fractional shares to provide the  amount
of  the periodic  withdrawal payment designated  in the  application. The shares
will be  redeemed at  their net  asset value  determined, at  the  shareholder's
option  on the tenth or twenty-fifth day (or next following business day) of the
relevant month or quarter and normally a  check for the proceeds will be  mailed
by  the Transfer Agent within  five business days after  the date of redemption.
The Withdrawal Plan may be terminated at any time by the Fund.
 
    Any shareholder who wishes to have  payments under the Withdrawal Plan  made
to  a third party or sent to an address other than the one listed on the account
must send complete written instructions to  the Transfer Agent to enroll in  the
Withdrawal  Plan.  The  shareholder's  signature on  such  instructions  must be
guaranteed  by  an   eligible  guarantor  acceptable   to  the  Transfer   Agent
(shareholders  should  contact  the Transfer  Agent  for a  determination  as to
whether a particular institution is  such an eligible guarantor). A  shareholder
may,  at any time change the amount  and interval of withdrawal payments and the
address to  which checks  are mailed  by written  notification to  the  Transfer
Agent. The shareholder's signature on such notification must be guaranteed by an
eligible  guarantor as described  above. The shareholder  may also terminate the
Systematic Withdrawal Plan at any time by written notice to the Transfer  Agent.
In the event of such termination, the account will be continued as a Shareholder
Investment  Account. The shareholder may  also redeem all or  part of the shares
held  in  the   Systematic  Withdrawal  Plan   account  (see  "Redemptions   and
Repurchases" in the Prospectus) at any time.
 
    DIRECT  INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
a shareholder may make additional investments in Fund shares at any time through
the Shareholder Investment Account  by sending a check  in any amount, not  less
than  $100, payable to Dean Witter Short-Term  Bond Fund, directly to the Fund's
Transfer Agent.  The investment  proceeds will  be applied  to the  purchase  of
shares
 
                                       33
<PAGE>
of  the Fund at the net asset value per share next computed after receipt of the
check or purchase payment by the Transfer Agent. The shares so purchased will be
credited to the investor's account.
 
   
    EXCHANGE PRIVILEGE.  As discussed  in the Prospectus, an Exchange  Privilege
exists  whereby investors who  have purchased shares  of any of  the Dean Witter
Funds sold with  either a front-end  (at time of  purchase) sales charge  ("FESC
funds")  or a  contingent deferred (at  time of redemption)  sales charge ("CDSC
funds") will be  permitted, after the  shares of the  fund acquired by  purchase
(not  by exchange or dividend  reinvestment) have been held  for thirty days, to
redeem all or part of their shares  in that fund and have the proceeds  invested
in  shares of the  Fund, Dean Witter  Limited Term Municipal  Trust, Dean Witter
Short-Term Treasury Trust,  Dean Witter Intermediate  Term U.S. Treasury  Trust,
Dean Witter Balanced Income Fund, Dean Witter Balanced Growth Fund and five Dean
Witter  Funds which are money market  funds (the foregoing eleven non-CDSC funds
are hereinafter referred to as the "Exchange Funds"). There is no waiting period
for  exchanges  of  shares  acquired  by  exchange  or  dividend   reinvestment.
Subsequently, shares of the Exchange Funds received in an exchange for shares of
an  FESC  fund (regardless  of the  type  of fund  originally purchased)  may be
redeemed and exchanged  for shares  of the Exchange  Funds, FESC  funds or  CDSC
funds  (however, shares of CDSC funds,  including shares acquired in exchange of
(i) shares  of FESC  funds  or (ii)  shares of  the  Exchange Funds  which  were
acquired  in exchange for shares of FESC  funds, may not be exchanged for shares
of FESC  funds). Additionally,  shares  of the  Exchange  Funds 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  the Exchange Funds  or
CDSC funds. Ultimately, any applicable contingent deferred sales charge ("CDSC")
will  have to be paid upon redemption of shares originally purchased from a CDSC
fund. An exchange will be treated for federal income tax purposes and applicable
state income tax purposes the same as  a repurchase or redemption of shares,  on
which the shareholder may realize a capital gain or loss.
    
 
    Any  new account  established through the  Exchange Privilege  will have the
same registration and cash dividend or dividend reinvestment plan as the present
account,  unless  the  Transfer  Agent  receives  written  notification  to  the
contrary.  For  telephone  exchanges,  the exact  registration  of  the existing
account and the account number must be provided.
 
    Any shares  held  in  certificate  form cannot  be  exchanged  but  must  be
forwarded  to the  Transfer Agent and  deposited into  the shareholder's account
before being eligible for exchange.  (Certificates mailed in for deposit  should
not be endorsed.)
 
    When shares of any CDSC fund are exchanged for shares of the Exchange Funds,
the exchange is executed at no charge to the shareholder, without the imposition
of  the  CDSC  at the  time  of the  exchange.  During  the period  of  time the
shareholder remains in the Exchange Funds  (calculated from the last day of  the
month  in which the Exchange  Fund shares were acquired),  the holding period or
"year since purchase payment  made" is frozen. When  shares are redeemed out  of
the  Exchange Fund, they will be subject to a CDSC which would be based upon the
period of  time  the  shareholder  held shares  in  a  CDSC  fund.  Shareholders
acquiring  shares of  an Exchange Fund  pursuant to this  exchange privilege may
exchange those shares back  into a CDSC  fund from the  Exchange Funds, with  no
CDSC  being imposed on such exchange.  The holding period previously frozen when
shares were first exchanged for shares of the Exchange Fund resumes on the  last
day  of the month in which shares of a CDSC fund are reacquired. Thus, a CDSC is
imposed only upon  an ultimate redemption,  based upon the  time (calculated  as
described  above) the shareholder was invested in  a CDSC fund. Shares of a CDSC
fund acquired in exchange for shares of an FESC fund (or in exchange for  shares
of other Dean Witter funds for which shares of an FESC fund have been exchanged)
are not subject to any CDSC upon their redemption.
 
    When  shares initially purchased in a CDSC  fund are exchanged for shares of
another CDSC fund or for shares of an Exchange Fund, the date of purchase of the
shares of the  fund exchanged into,  for purposes of  the CDSC upon  redemption,
will  be the  last day  of the month  in which  the shares  being exchanged were
originally purchased.  In allocating  the purchase  payments between  funds  for
purposes of the CDSC, the amount which represents the current net asset value of
shares at the time of the
 
                                       34

exchange which were (i) purchased more than three or six years (depending on the
CDSC  schedule applicable to the shares)  prior to the exchange, (ii) originally
acquired through reinvestment of dividends  or distributions and (iii)  acquired
in  exchange for shares of FESC funds, or  for shares of other Dean Witter Funds
for which shares of FESC funds have been exchanged (all such shares called "Free
Shares"), will be  exchanged first. Shares  of Dean Witter  American Value  Fund
acquired  prior  to  April  30,  1984, shares  of  Dean  Witter  Dividend Growth
Securities Inc. and  Dean Witter  Natural Resource  Development Securities  Inc.
acquired  prior  to July  2, 1984,  and  shares of  Dean Witter  Strategist Fund
acquired prior to November 8, 1989 are  also considered Free Shares and will  be
the  first Free Shares to be exchanged.  After an exchange, all dividends earned
on shares in the Fund or the  money market fund will be considered Free  Shares.
If  the exchanged amount exceeds  the value of such  Free Shares, an exchange is
made, on a block-by-block basis, of non-Free Shares held for the longest  period
of time (except that if shares held for identical periods of time but subject to
different  CDSC schedules are  held in the same  Exchange Privilege Account, the
shares of that block that are subject  to the lower CDSC rate will be  exchanged
prior  to the  shares of  that block that  are subject  to a  higher CDSC rate).
Shares equal to any appreciation in the value of non-Free Shares exchanged  will
be  treated as  Free Shares,  and the  amount of  the purchase  payments for the
non-Free Shares of the fund  exchanged into will be equal  to the lesser of  (a)
the  purchase payments for, or (b) the current net asset value of, the exchanged
non-Free Shares. If an exchange between  funds would result in exchange of  only
part  of  a  particular block  of  non-Free  Shares, then  shares  equal  to any
appreciation in the value of the block  (up to the amount of the exchange)  will
be treated as Free Shares and exchanged first, and the purchase payment for that
block  will be allocated on a prorata  basis between the non-Free Shares of that
block to  be retained  and the  non-Free Shares  to be  exchanged. The  prorated
amount  of such  purchase payment attributable  to the  retained non-Free Shares
will remain as the purchase payment for such shares, and the amount of  purchase
payment for the exchanged non-Free Shares will be equal to the lesser of (a) the
prorated  amount of the purchase payment for, or (b) the current net asset value
of, those exchanged non-Free Shares. Based upon the procedures described in  the
CDSC  fund Prospectus under the caption  "Contingent Deferred Sales Charge", any
applicable CDSC will be  imposed upon the ultimate  redemption of shares of  any
fund,  regardless of the number of  exchanges since those shares were originally
purchased.
    
 
    With respect to  exchanges, redemptions or  repurchases, the Transfer  Agent
shall  be liable for its own negligence and not for the default or negligence of
its correspondents or for losses  in transit. The Fund  shall not be liable  for
any default or negligence of the Transfer Agent, the Distributor or any Selected
Broker-Dealer.
 
    The Distributor and any Selected Broker-Dealer have authorized and appointed
the  Transfer Agent to act as their  agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission  or
discounts  will be paid to the Distributor or any Selected Broker-Dealer for any
transactions pursuant to this Exchange Privilege.
 
    Exchanges are subject to  the minimum investment  requirement and any  other
conditions  imposed by each fund. (The  minimum initial investment is $5,000 for
Dean Witter Liquid  Asset Fund Inc.,  Dean Witter Tax-Free  Daily Income  Trust,
Dean  Witter New  York Municipal Money  Market Trust and  Dean Witter California
Tax-Free Daily  Income Trust,  although those  funds may,  at their  discretion,
accept  initial investments of as low  as $1,000. The minimum initial investment
for Dean Witter Short-Term U.S. Treasury  Trust is $10,000, although that  fund,
in  its discretion,  may accept  initial investments  of as  low as  $5,000. The
minimum initial  investment  for all  other  Dean  Witter Funds  for  which  the
Exchange Privilege is available is $1,000.) Upon exchange into an Exchange Fund,
the  shares of that  fund will be  held in a  special Exchange Privilege Account
separately from accounts of  those shareholders who  have acquired their  shares
directly  from that  fund. As a  result, certain services  normally available to
shareholders of  Dean Witter  Short-Term U.S.  Treasury or  money market  funds,
including  the check writing  feature, will not  be available for  funds held in
that account.

    The Fund and each  of the other  Dean Witter Funds may  limit the number  of
times  this  Exchange  Privilege  may  be exercised  by  any  investor  within a
specified period of  time. Also,  the Exchange  Privilege may  be terminated  or
revised  at any time by the  fund and/or any of the  Dean Witter Funds for which
shares of the Fund have been exchanged,  upon such notice as may be required  by
applicable  regulatory agencies (presently sixty  days' prior written notice for
termination or  material  revision), provided  that  six months'  prior  written
notice  of termination  will be  given to  the shareholders  who hold  shares of
Exchange Funds, pursuant to  this Exchange Privilege  and provided further  that
the Exchange Privilege may be terminated or materially revised without notice at
times  (a) when the New  York Stock Exchange is  closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists  as a result  of which  disposal by the  Fund of  securities
owned  by it is not  reasonably practicable or it  is not reasonably practicable
for the Fund fairly  to determine the  value of its net  assets, (d) during  any
other  period when  the Securities and  Exchange Commission by  order so permits
(provided that applicable rules and  regulations of the Securities and  Exchange
Commission  shall govern as to  whether the conditions prescribed  in (b) or (c)
exist) or (e)  if the  Fund would  be unable  to invest  amounts effectively  in
accordance with its investment objective, policies and restrictions.
    
 
    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  may  be
exchanged, upon such notice as may be required by applicable regulatory agencies
(presently  sixty  days'  prior  written  notice  for  termination  or  material
revision), provided that six months' prior  notice of termination will be  given
to  shareholders  who hold  shares of  Exchange Funds  pursuant to  the Exchange
Privilege, and provided further that the Exchange Privilege may be terminated or
materially  revised  without   notice  under   certain  unusual   circumstances.
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 of  the Dean  Witter Funds  describes its
investment objective(s) and policies. Shareholders should obtain a copy and read
it carefully before investing.  Exchange are subject  to the minimum  investment
requirement  and any other conditions  imposed by each Fund.  In the case of any
shareholder holding a share  certificate or certificates,  not exchanges may  be
made  until all applicable share certificates have been received by the Transfer
Agent and deposited in  the shareholder's account. An  exchange will be  treated
for federal income tax purposes the same as a repurchase or redemption of shares
on  which the  shareholder will  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.
 
    For  further  information  regarding  the  Exchange  Privilege, shareholders
should contact their account executives or the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment for shares presented for repurchase or redemption will be made by  check
within  seven days after receipt by the Transfer Agent of the certificate and/or
written request  in good  order. The  term  "good order"  means that  the  share
certificate,   if  any,  and  request   for  redemption,  are  properly  signed,
accompanied by  any  documentation required  by  the Transfer  Agent,  and  bear
signature  guarantees  when required  by the  Fund or  the Transfer  Agent. Such
payment may be postponed or the right of redemption suspended at times (a)  when
the  New York  Stock Exchange  is closed for  other than  customary weekends and
holidays, (b) when trading on that Exchange is restricted, (c) when an emergency
exists as a result of  which disposal by the Fund  of securities owned by it  is
not  reasonably practicable  or it  is not  reasonably practicable  for the Fund
fairly to determine the value of its  net assets, or (d) during any period  when
the  Securities  and  Exchange Commission  by  order so  permits;  provided that
applicable rules and regula-
 
                                       36
<PAGE>
tions  of the Securities and Exchange Commission  shall govern as to whether the
conditions prescribed in (b) or (c) exist.
 
    INVOLUNTARY REDEMPTION.    As  described  in  the  Prospectus,  due  to  the
relatively  high cost of handling small investments, the Fund reserves the right
to redeem, at net asset value, the shares of any shareholder whose shares have a
value of less than $100, or such lesser  amount as may be fixed by the Board  of
Trustees. 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 $100 and allow him or her 60 days to make an additional investment  in
an  amount which will increase the  value of his or her  account to $100 or more
before the redemption is processed.
 
    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder  who
has  had  his or  her  shares redeemed  or  repurchased and  has  not previously
exercised this reinstatement privilege may, within 30 days after the  redemption
or  repurchase, reinstate any portion or all  of the proceeds of such redemption
or repurchase in shares  of the Fund  held by the shareholder  at the net  asset
value next determined after a reinstatement request, together with the proceeds,
is received by the Transfer Agent.
 
    Exercise  of the reinstatement privilege will  not affect the federal income
tax and  state income  tax  treatment of  any gain  or  loss realized  upon  the
redemption  or repurchase, except that if  the redemption or repurchase resulted
in a loss and reinstatement is  made in shares of the  Fund, some or all of  the
loss, depending on the amount reinstated, will not be allowed as a deduction for
federal income tax and state personal income tax purposes but will be applied to
adjust the cost basis of the shares acquired upon reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    The  Fund  intends  to  qualify  and elect  to  be  treated  as  a regulated
investment company for  each taxable  year under  the Internal  Revenue Code  of
1986,  as  amended (the  "Code").  To so  qualify,  the Fund  must  meet certain
requirements as to the nature of its income and the nature of its assets.
 
    As a regulated investment  company, the Fund will  not be subject to  United
States federal income tax on its income that it distributes to its shareholders,
provided  that an amount equal to at least 90% of its investment company taxable
income (i.e., 90% of  its taxable income  minus the excess, if  any, of its  net
realized long-term capital gains over its net realized short-term capital losses
including  any capital loss carryovers), plus or minus certain other adjustments
as specified in section 852  of the Code) for  the taxable year is  distributed,
but  will be subject  to tax at regular  corporate rates on  any income or gains
that it does not distribute. Furthermore, the  Fund will be subject to a  United
States corporate income tax with respect to such distributed amounts in any year
that it fails to qualify as a regulated investment company or fails to meet this
distribution requirement.
 
    The Fund will determine either to distribute or to retain all or part of any
net  long-term capital gains in any year for reinvestment. If any such gains are
retained, the Fund expects to  designate such retained amounts as  undistributed
capital  gains  in a  notice to  its shareholders  who (a)  will be  required to
include in income for  United States federal income  tax purposes, as  long-term
capital  gains, their proportionate shares of the undistributed amount, (b) will
be entitled to credit their proportionate shares of the 35% tax paid by the Fund
on the  undistributed amount  against  their United  States federal  income  tax
liabilities,  if any, and  to claim refunds  to the extent  their credits exceed
their liabilities, if any, and (c) will be entitled to increase their tax basis,
for United States  federal income  tax purposes, in  their shares  by an  amount
equal  to  65% of  the amount  of  undistributed capital  gains included  in the
shareholder's income.
 
    The Code imposes a 4% nondeductible excise tax on the Fund to the extent the
Fund does not distribute by the end of any calendar year at least 98% of its net
investment income for that year and 98%  of the net amount of its capital  gains
(both long-and short-term) for the one-year period ending, as a general rule, on
October  31 of that year. For this purpose, however, any income or gain retained
by the Fund that is subject to  corporate income tax will be considered to  have
been distributed by year-end.
 
                                       37
<PAGE>
The  Fund  anticipates  that it  will  pay  such dividends  and  will  make such
distributions as are necessary in order to avoid the application of this tax.
 
    Gains or  losses  on sales  of  securities by  the  Fund will  generally  be
long-term  capital gains or losses if the  securities have been held by the Fund
for more than twelve months. Gains or losses on the sale of securities held  for
twelve months or less will be generally short-term gains or losses.
 
    Gains  or losses  on the  Fund's transactions  in certain  listed options on
securities and  on futures  and  options on  futures  traded on  U.S.  exchanges
generally  are treated as 60% long-term gain  or loss and 40% short-term gain or
loss. When the  Fund engages in  options and futures  transactions, various  tax
regulations  applicable to the Fund  may have the effect  of causing the Fund to
recognize a gain or loss for tax purposes before that gain or loss is  realized,
or  to defer recognition of  a realized loss for  tax purposes. Recognition, for
tax purposes, of an unrealized loss may result in a lesser amount of the  Fund's
realized net gains being available for distribution.
 
    As  a regulated investment  company, the Fund is  subject to the requirement
that less than  30% of  its gross  income be derived  from the  sale of  certain
investments  held for  less than  three months.  This requirement  may limit the
Fund's ability to engage in options and futures transactions and to engage in  a
large number of short-term transactions.
 
    The  Fund may invest in securities  having original issue discount which may
generate income in excess  of the cash received  by the Fund. Consequently,  the
Fund  may be  required to  borrow or  to liquidate  securities in  order to make
distributions.
 
    Any dividend or capital  gains distribution received  by a shareholder  from
any  investment company will have the effect  of reducing the net asset value of
the shareholder's stock in that company by  the exact amount of the dividend  or
capital   gains  distribution.  Furthermore,  capital  gains  distributions  and
dividends are subject to  federal income taxes.  If the net  asset value of  the
shares  should be reduced below a shareholder's  cost as a result of the payment
of dividends or the distribution of  realized net long-term capital gains,  such
payment  or  distribution  would  be  in  part  a  return  of  the shareholder's
investment to the  extent of such  reduction below the  shareholder's cost,  but
nonetheless  would be fully taxable. Therefore,  an investor should consider the
tax implications of purchasing Fund  shares immediately prior to a  distribution
record date.
 
    Distributions  in excess of the Fund's  current and accumulated earnings and
profits will,  as  to each  shareholder,  be treated  as  a tax-free  return  of
capital,  to the extent of a shareholder's basis  in his shares of the Fund, and
as a capital gain thereafter (if the  shareholder held his or her shares of  the
Fund as capital assets).
 
    Shareholders  receiving dividends or distributions in the form of additional
Fund shares should be treated for  United States federal income tax purposes  as
receiving  a distribution  in an amount  equal to  the amount of  money that the
shareholders receiving cash dividends or distributions will receive, and  should
have a cost basis in the shares received equal to such amount.
 
    Any  loss realized on the redemption by  a shareholder of his shares will be
disallowed to  the  extent  the  shares  disposed  of  are  replaced,  including
replacement through the reinvesting of dividends and capital gains distributions
in the Fund, within a period (of 61 days) beginning 30 days before and ending 30
days  after the  disposition of  the shares. In  such a  case, the  basis of the
shares acquired  will be  increased to  reflect the  disallowed loss.  Any  loss
realized  by a shareholder on  the sale of a Fund  share held by the shareholder
for six months or less will be treated for United States income tax purposes  as
a  long-term  capital  loss  to  the  extent  of  any  distributions  or  deemed
distributions of  long-term  capital  gains received  by  the  shareholder  with
respect to such share.
 
    Distributions  may  also  be  subject  to  state,  local  and  foreign taxes
depending on each shareholder's particular situation.
 
    SPECIAL RULES FOR CERTAIN FOREIGN CURRENCY TRANSACTIONS.  In general,  gains
from  foreign  currencies and  from foreign  currency options,  foreign currency
futures and forward foreign exchange contracts
 
                                       38
<PAGE>
relating to investments in stock, securities or foreign currencies are currently
considered to be qualifying income for purposes of determining whether the  Fund
qualifies  as a regulated investment company.  It is currently unclear, however,
who will be treated as the issuer of certain foreign currency instruments or how
foreign currency options, futures, or forward foreign currency contracts will be
valued  for  purposes  of  the  regulated  investment  company   diversification
requirements  applicable  to the  Fund. The  Fund may  request a  private letter
ruling from the Internal Revenue Service on some or all of these issues.
 
    Under Code Section 988, special rules are provided for certain  transactions
in  a  foreign currency  other than  the  taxpayer's functional  currency (I.E.,
unless certain special rules apply, currencies  other than the U.S. dollar).  In
general,  foreign currency gains or losses  from forward contracts, from futures
contracts that are not "regulated futures contracts," and from unlisted  options
will be treated as ordinary income or loss under Code Section 988. Also, certain
foreign  exchange gains or  losses derived with  respect to foreign fixed-income
securities are also  subject to  Section 988 treatment.  In general,  therefore,
Code  Section 988 gains  or losses will  increase or decrease  the amount of the
Fund's  investment  company  taxable  income  available  to  be  distributed  to
shareholders as ordinary income, rather than increasing or decreasing the amount
of  the Fund's net capital gain. Additionally, if Code Section 988 losses exceed
other investment company taxable income during a taxable year, the Fund may  not
be  able  to make  any ordinary  dividend  distributions and  distributions paid
during the year may be characterized for tax purposes as a return of capital.
 
    Exchange control regulations may restrict repatriations of investment income
and capital or the proceeds of securities sales by foreign investors such as the
Fund and may limit the  Fund's ability to pay  sufficient dividends and to  make
sufficient  distributions  to  satisfy  the  90%  and  excise  tax  distribution
requirements.
 
    The Fund's transactions, if any,  in foreign currencies, forward  contracts,
options  and  futures  contracts  (including options  and  futures  contracts on
foreign currencies) may be subject to special provisions of the Code that, among
other things, may affect the character of gains and losses realized by the  Fund
(i.e.,  may affect whether gains or  losses are ordinary or capital), accelerate
recognition of  income to  the Fund  and defer  Fund losses.  These rules  could
therefore   affect  the  character,  amount   and  timing  of  distributions  to
shareholders. These  rules also  (a) could  require the  Fund to  mark-to-market
certain  types of the positions in its  portfolio (i.e., treat them as they were
closed out) and  (b) may cause  the Fund to  recognize income without  receiving
cash  with which to pay dividends or  make distributions in amounts necessary to
satisfy the distribution requirements for avoiding income and excise taxes.
 
    The foregoing discussion  is a  general summary  of certain  of the  current
Federal  income tax laws  regarding the Fund and  investors. The discussion does
not purport to deal with all  of the Federal income tax consequences  applicable
to  the Fund, or to all categories of investors, some of which may be subject to
special rules. Investors should consult their own tax advisors regarding the tax
consequences to them of investments in shares.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    As discussed in the  Prospectus, from time  to time the  Fund may quote  its
"yield"  and/or its "total return" in advertisements and sales literature. Yield
is calculated for any  30-day period as follows:  the amount of interest  and/or
dividend  income  for each  security in  the Fund's  portfolio is  determined in
accordance with  regulatory requirements;  the total  for the  entire  portfolio
constitutes  the Fund's gross income for the period. Expenses accrued during the
period are subtracted to arrive at "net investment income". The resulting amount
is divided by the product of  the net asset value per  share on the last day  of
the  period multiplied by  the average number of  Fund shares outstanding during
the period that were entitled to dividends. This amount is added to 1 and raised
to the sixth power. 1 is then  subtracted from the result and the difference  is
multiplied  by  2 to  arrive at  the  annualized yield.  Based on  the foregoing
calculation, the Fund's annualized  yield for the thirty  (30) day period  ended
April  30, 1996 was 5.29%. Without the waiver of fees and assumption of expenses
by the Investment Manager, the Fund's  annualized yield for the thirty (30)  day
period ended April 30, 1996 would have been 4.99%.
    
 
                                       39
<PAGE>
   
    The  Fund's "average annual total return" represents an annualization of the
Fund's total return  over a  particular period and  is computed  by finding  the
annual  percentage rate which  will result in  the ending redeemable  value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten  year
period,  or  for  the  period  from  the  date  of  commencement  of  the Fund's
operations, if  shorter than  any of  the  foregoing. For  the purpose  of  this
calculation,  it is assumed that all dividends and distributions are reinvested.
The formula for computing the average annual total return involves a  percentage
obtained  by dividing the ending  redeemable value by the  amount of the initial
investment, taking a root of the quotient  (where the root is equivalent to  the
number  of years in the period) and subtracting  1 from the result. Based on the
foregoing calculation, the  Fund's average  annual total return  for the  fiscal
year  ended  April  30, 1996  was  7.33% and  for  the period  January  10, 1994
(commencement of  operations) through  April  30, 1996  was 4.30%.  Without  the
waiver of fees and assumption of expenses by the Investment Manager, the average
annual total return would have been 6.20% and 2.91%, respectively.
    
 
   
    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time by means of aggregate, year-by-year or other types  of
total  return figures.  In addition,  the Fund  may compute  its aggregate total
return for specified periods by determining the aggregate percentage rate  which
will  result in the ending value of a hypothetical $1,000 investment made at the
beginning of the period. For the purpose of this calculation, it is assumed that
all dividends  and  distributions  are reinvested.  The  formula  for  computing
aggregate  total return  involves a percentage  obtained by  dividing the ending
value by the initial $1,000 investment and subtracting 1 from the result.  Based
on  the foregoing calculation, the Fund's  aggregate total return for the fiscal
year ended  April  30, 1996  was  7.33% and  for  the period  January  10,  1994
(commencement of operations) through April 30, 1996 was 10.18%.
    
 
   
    The  Fund  may  also advertise  the  growth of  hypothetical  investments of
$10,000, $50,000 and $100,000 in  shares of the Fund by  adding 1 to the  Fund's
aggregate  total return and multiplying by  $10,000, $50,000 or $100,000, as the
case may  be.  Investments of  $10,000,  $50,000 and  $100,000  in the  Fund  at
inception  would have  grown to $11,018,  $55,090 and  $110,180, respectively at
April 30, 1996.
    
 
    The Fund from time  to time may also  advertise its performance relative  to
certain performance rankings and indexes compiled by independent organizations.
 
DESCRIPTION OF SHARES
- --------------------------------------------------------------------------------
 
   
    The shareholders of the Fund are entitled to a full vote for each full share
held.  The Trustees were elected by InterCapital  as the sole shareholder of the
Fund prior to the public offering of the Fund's shares. The Trustees  themselves
have  the power to alter the number and the terms of office of the Trustees, and
they may at any time lengthen their  own terms or make their terms of  unlimited
duration  and  appoint their  own successors,  provided that  always at  least a
majority of the Trustees has been elected by the shareholders of the Fund. Under
certain circumstances the Trustees may be removed by action of the Trustees. The
shareholders also have  the right  to remove  the Trustees  following a  meeting
called  for that purpose requested in writing  by the record holders of not less
than ten  percent  of  the  Fund's outstanding  shares.  The  voting  rights  of
shareholders  are not cumulative, so that holders of more than 50 percent of the
shares voting can, if they choose, elect all Trustees being selected, while  the
holders of the remaining shares would be unable to elect any Trustees.
    
 
    The  Declaration of Trust permits the  Trustees to authorize the creation of
additional series  of  shares  (the  proceeds of  which  would  be  invested  in
separate,  independently managed  portfolios) and  additional classes  of shares
within any  series (which  would be  used  to distinguish  among the  rights  of
different categories of shareholders, as might be required by future regulations
or  other unforeseen circumstances).  However, the Trustees  have not authorized
any such additional series or classes of shares.
 
    The Declaration  of Trust  provides that  no Trustee,  officer, employee  or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer,    employee    or   agent    liable   to    any   third    persons   in
 
                                       40

connection with the affairs of the Fund, except as such liability may arise from
his or her  own bad faith,  willful misfeasance, gross  negligence, or  reckless
disregard  of his or her  duties. It also provides  that all third persons shall
look solely  to  the Fund's  property  for  satisfaction of  claims  arising  in
connection  with  the  affairs of  the  Fund.  With the  exceptions  stated, the
Declaration of Trust  provides that  a Trustee,  officer, employee  or agent  is
entitled  to  be  indemnified against  all  liabilities in  connection  with the
affairs of the Fund.
 
    The Fund is authorized to issue an unlimited number of shares of  beneficial
interest.  The Fund shall be of unlimited  duration subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER SHORT-TERM BOND FUND
NOTES TO FINANCIAL STATEMENTS APRIL 30, 1996
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Short-Term Bond Fund (the "Fund") is registered under the Investment
Company Act of 1940, as amended, as a diversified, open-end management
investment company. The Fund's investment objective is to provide a high level
of current income consistent with the preservation of capital. The Fund seeks to
achieve its objective by investing in a diversified portfolio of short-term
fixed income securities. The Fund was organized as a Massachusetts business
trust on October 22, 1993 and commenced operations on January 10, 1994.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates. The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) all portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (2) when market
quotations are not readily available, portfolio securities are valued at their
fair value as determined in good faith under procedures established by and under
the general supervision of the Trustees (valuation of securities for which
market quotations are not readily available may be based upon current market
prices of securities which are comparable in coupon, rating and maturity or an
appropriate matrix utilizing similar factors); (3) certain portfolio securities
may be valued by an outside pricing service approved by the Trustees. The
pricing service utilizes a matrix system incorporating security quality,
maturity and coupon as the evaluation model parameters, and/or research and
evaluation by its staff, including review of broker-dealer market price
quotations, if available, in determining what it believes is the fair valuation
of the portfolio securities valued by such pricing service; and (4) short-term
debt securities having a maturity date of more than sixty days at the time of
purchased are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily.

<PAGE>
DEAN WITTER SHORT-TERM BOND FUND
NOTES TO FINANCIAL STATEMENTS APRIL 30, 1996, CONTINUED
 
C. FOREIGN CURRENCY TRANSLATION -- The books and records of the Fund are
maintained in U.S. dollars as follows: (1) the foreign currency market value of
investment securities, other assets and liabilities and forward contracts are
translated at the exchange rates prevailing at the end of the period; and (2)
purchases, sales, income and expenses are translated at the exchange rate
prevailing on the respective dates of such transactions. The resultant exchange
gains and losses are included in the Statement of Operations. Pursuant to U.S.
Federal income tax regulations, certain foreign exchange gains/losses included
in realized and unrealized gain/loss are included in or are a reduction of
ordinary income for federal income tax purposes. The Fund does not isolate that
portion of the results of operations arising as a result of changes in the
foreign exchange rates from the changes in the market prices of the securities.
 
D. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.
 
E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.
 
F. ORGANIZATIONAL EXPENSES -- Dean Witter InterCapital Inc. (the "Investment
Manager") paid the organizational expenses of the Fund in the amount of
approximately $173,000 which has been reimbursed, exclusive of any amounts
assumed. Such expenses have been deferred and are being amortized on the
straight-line method over a period not to exceed five years from the
commencement of operations.

2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, the Fund pays a management fee,
accrued daily and payable monthly, by applying the annual rate of 0.70% to the
net assets of the Fund determined as of the close of each business day.
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.
 
The Investment Manager had undertaken to reimburse the Fund for all expenses
(except for any brokerage fees and a portion of the organizational expenses) and
waive the compensation (the "management fee") provided for in the Agreement
until December 31, 1995. At April 30, 1996, included in the Statement of Assets
and Liabilities are receivables from affiliate which represent expense
reimbursements due the Fund. For the period January 1, 1996 through December 31,
1996, the Investment Manager will continue to waive the management fee and
reimburse expenses to the extent they exceed 1.00% of daily net assets or until
such time as the Fund has $50 million of net assets, whichever occurs first.
 
3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales/prepayments of portfolio
securities, excluding short-term investments, for the year ended April 30, 1996
were $23,150,897 and $18,800,532, respectively. Included in the aforementioned
are purchases and sales of U.S. Government securities of $10,953,035 and
$10,895,409, respectively.
 
Dean Witter Trust Company, an affiliate of the Investment Manager, is the Fund's
transfer agent.

5. FEDERAL INCOME TAX STATUS
 
At April 30, 1996, the Fund had a net capital loss carryover of approximately
$879,000 of which $378,000 will be available through April 30, 2003 and $501,000
will be available through April 30, 2004 to offset future capital gains to the
extent provided by regulations. To the extent that this carryover loss is used
to offset future capital gains, it is probable that the gains so offset will not
be distributed to shareholders.
 
Capital losses incurred after October 31 ("post-October losses") within the
taxable year are deemed to arise on the first business day of the Fund's next
taxable year. The Fund incurred and will elect to defer net capital losses of
approximately $51,000 during fiscal 1996. As of April 30, 1996 the Fund had
temporary book/tax differences primarily attributable to post-October losses and
permanent book/ tax differences attributable to foreign currency losses. To
reflect reclassifications arising from permanent book/tax differences for the
year ended April 30, 1996, distributions in excess of net investment income was
charged and accumulated net realized loss was credited $661,836.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER SHORT-TERM BOND FUND
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter Short-Term Bond Fund
(the "Fund") at April 30, 1996, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended and the financial highlights for each of the two years then ended and
for the period January 10, 1994 (commencement of operations) through April 30,
1994, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at April
30, 1996 by correspondence with the custodian, provide a reasonable basis for
the opinion expressed above.

RATINGS OF CORPORATE DEBT INSTRUMENTS INVESTMENTS
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
           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-rate 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  exposures 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  have 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>
 
                                       55
<PAGE>
<TABLE>
<S>        <C>
CCC        Fixed-income  securities rated "CCC"  have a current  identifiable vulnerability to
           default,  and  are  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, they are 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.

                                  BOND RATINGS
FITCH INVESTORS SERVICE, INC. ("FITCH")
 
    The  Fitch Bond  Ratings provides  a guide  to investors  in determining the
investment risk associated with a particular security. The rating represents its
assessment of the issuer's  ability to meet the  obligations of a specific  debt
issue  or  class  of  debt  in  a timely  manner.  Fitch  bond  ratings  are not
recommendations to  buy,  sell or  hold  securities since  they  incorporate  no
information on market price or yield relative to other debt instruments.
 
    The  rating  takes into  consideration special  features  of the  issue, its
relationship to other obligations of the issuer, the record of the issuer and of
any guarantor, as  well as  the political  and economic  environment that  might
affect the future financial strength and credit quality of the issuer.
 
                                       56
<PAGE>
    Bonds  which  have  the  same  rating are  of  similar  but  not necessarily
identical investment  quality  since the  limited  number of  rating  categories
cannot  fully reflect  small differences  in the  degree of  risk. Moreover, the
character of  the risk  factor  varies from  industry  to industry  and  between
corporate, health care and municipal               .
 
    In  assessing  credit  risk,  Fitch  Investors  Service  relies  on  current
information furnished by the issuer and/or guarantor and other sources which  it
considers  reliable. Fitch does not perform an audit of the financial statements
used in assigning a rating.
 
    Ratings may  be changed,  withdrawn  or suspended  at  any time  to  reflect
changes  in  the financial  condition of  the  issuer, the  status of  the issue
relative to other  debt of  the issuer, or  any other  circumstances that  Fitch
considers to have a material effect on the credit of the obligor.
 
<TABLE>
<S>        <C>
AAA        rated  bonds  are considered  to  be investment  grade  and of  the  highest credit
           quality. The obligor has an exceptionally strong ability to pay interest and  repay
           principal, which is unlikely to be affected by reasonably foreseeable events.
AA         rated  bonds are considered to be investment grade and of very high credit quality.
           The obligor's ability to  pay interest and repay  principal, while very strong,  is
           somewhat less than for AAA rated securities or more subject to possible change over
           the term of the issue.
A          rated  bonds are considered to be investment  grade and of high credit quality. The
           obligor's ability to pay interest and  repay principal is considered to be  strong,
           but  may  be  more  vulnerable  to  adverse  changes  in  economic  conditions  and
           circumstances than bonds with higher ratings.
BBB        rated bonds  are considered  to  be investment  grade  and of  satisfactory  credit
           quality. The obligor's ability to pay interest and repay principal is considered to
           be adequate. Adverse changes in economic conditions and circumstances, however, are
           more likely to weaken this ability than bonds with higher ratings.
BB         rated  bonds are considered speculative and  of low investment grade. The obligor's
           ability to pay interest and repay principal is not strong and is considered  likely
           to be affected over time by adverse economic changes.
B          rated  bonds are  considered highly  speculative. Bonds  in this  class are lightly
           protected as to the obligor's  ability to pay interest over  the life of the  issue
           and repay principal when due.
CCC        rated  bonds may have certain identifiable  characteristics which, if not remedied,
           could lead to the possibility of default in either principal or interest payments.
CC         rated bonds  are  minimally  protected.  Default  in  payment  of  interest  and/or
           principal seems probable.
C          rated bonds are in imminent default in payment of interest or principal.

                               SHORT-TERM RATINGS
 
    Fitch's  short-term ratings  apply to debt  obligations that  are payable on
demand or have  original maturities of  generally up to  three years,  including
commercial  paper, certificates of deposit, medium-term notes, and municipal and
investment notes. Although the credit analysis is similar to Fitch's bond rating
analysis, the  short-term rating  places greater  emphasis on  the existence  of
liquidity necessary to meet the issuer's obligations in a timely manner. Fitch's
short-term ratings are as follows:
 
<TABLE>
<S>        <C>
Fitch-1+   (Exceptionally  Strong Credit Quality) Issues  assigned this rating are regarded
           as having the strongest degree of assurance for timely payment.
Fitch-1    (Very Strong Credit Quality) Issues assigned this rating reflect an assurance of
           timely payment only slightly less in degree than issues rated Fitch-1+.
Fitch-2    (Good Credit Quality) Issues assigned this rating have a satisfactory degree  of
           assurance for timely payment but the margin of safety is not as great as the two
           higher categories.

<TABLE>
<S>        <C>
Fitch-3    (Fair   Credit  Quality)  Issues  assigned   this  rating  have  characteristics
           suggesting that the degree of assurance for timely payment is adequate, however,
           near-term adverse change is likely to  cause these securities to be rated  below
           investment grade.
Fitch-S    (Weak   Credit  Quality)  Issues  assigned   this  rating  have  characteristics
           suggesting a minimal degree of assurance  for timely payment and are  vulnerable
           to near term adverse changes in financial and economic conditions.
D          (Default) Issues assigned this rating are in actual or imminent payment default.
LOC        This  symbol LOC indicates that the rating is based on a letter of credit issued
           by a commercial bank.

                               LONG-TERM RATINGS
DUFF & PHELPS, INC.
 
    These  ratings  represent  a  summary  opinion  of  the  issuer's  long-term
fundamental   quality.  Rating   determination  is  based   on  qualitative  and
quantitative factors  which  may  vary  according  to  the  basic  economic  and
financial   characteristics  of   each  industry  and   each  issuer.  Important
considerations are vulnerability to economic cycles as well as risks related  to
such  factors  as  competition,  government  action,  regulation,  technological
obsolescence, demand shifts, cost structure, and management depth and expertise.
The projected viability of the obligor at the trough of the cycle is a  critical
determination.
 
    Each  rating also takes into account the  legal form of the security, (e.g.,
first mortgage bonds, subordinated debt,  preferred stock, etc.). The extent  of
rating  dispersion  among the  various classes  of  securities is  determined by
several factors including relative weightings of the different security  classes
in  the capital structure,  the overall credit  strength of the  issuer, and the
nature of covenant protection. Review of indenture restrictions is important  to
the analysis of a company's operating and financial constraints.
 
    The  Credit Rating Committee  formally reviews all  ratings once per quarter
(more frequently, if necessary).

<CAPTION>
RATING SCALE     DEFINITION
 
<S>              <C>
AAA              Highest credit quality. The risk factors are negligible, being only slightly more than  risk-free
                 U.S. Treasury debt.
 
AA+              High  credit quality. Protection factors  are strong. Risk is modest,  but may vary slightly from
AA               time to time because of economic conditions.
AA-
 
A+               Protection factors are average but adequate. However, risk factors are more variable and  greater
A                in periods of economic stress.
A
BBB+             Below  average  protection  factors  but  still  considered  sufficient  for  prudent investment.

BB+              Below investment grade but  deemed likely to  meet obligations when  due. Present or  prospective
BB               financial  protection factors  fluctuate according  to industry  conditions or  company fortunes.
BB-              Overall quality may move up or down frequently within this category.
 
B+               Below investment grade and possessing risk that  obligations will not be met when due.  Financial
B                protection factors will fluctuate widely according to economic cycles, industry conditions and/or
B-               company  fortunes.  Potential exists  for  frequent changes  in  the quality  rating  within this
                 category or into a higher or lower quality rating grade.

CCC              Well below investment grade securities. May be in default or have considerable uncertainty exists
                 as to timely payment of principal, interest or preferred dividends. Protection factors are narrow
                 and risk  can  be  substantial  with  unfavorable  economic/  industry  conditions,  and/or  with

                               SHORT-TERM RATINGS
 
    Duff & Phelps' short-term  ratings are consistent  with the rating  criteria
utilized by money market participants. The ratings apply to all obligations with
maturities  of under one year, including commercial paper, the uninsured portion
of  certificates  of  deposit,  unsecured  bank  loans,  master  notes,  bankers
acceptances,  irrevocable letters of credit, and current maturities of long-term
debt. Asset-backed commercial paper is also rated according to this scale.
 
    Emphasis is  placed on  liquidity which  is defined  as not  only cash  from
operations,  but also  access to  alternative sources  of fund,  including trade
credit, bank lines, and the capital  markets. An important consideration is  the
level of an obligor's reliance on short-term funds on an ongoing basis.
 
<TABLE>
<S>                  <C>
    A. CATEGORY 1:   HIGH GRADE
    Duff 1+          Highest  certainty of  timely payment.  Short-term liquidity, including
                      internal operating  factors and/or  access to  alternative sources  of
                      funds,  is  outstanding,  and  safety  is  just  below  risk-free U.S.
                      Treasury short-term obligations.
    Duff 1           Very high certainty of timely payment. Liquidity factors are  excellent
                      and supported by good fundamental protection factors. Risk factors are
                      minor.
    Duff-            High  certainty  of timely  payment. Liquidity  factors are  strong and
                      supported by  good fundamental  protection factors.  Risk factors  are
                      very small.
 
    B. CATEGORY 2:   GOOD GRADE
    Duff 2           Good  certainty  of  timely  payment.  Liquidity  factors  and  company
                      fundamentals are  sound. Although  ongoing funding  needs may  enlarge
                      total  financing requirements, access to capital markets is good. Risk
                      factors are small.
 
    C. CATEGORY 3:   SATISFACTORY GRADE
    Duff 3           Satisfactory liquidity and other protection factors qualify issue as to
                      investment  grade.  Risk  factors  are  larger  and  subject  to  more
                      variation. Nevertheless, timely payment is expected.
 
    D. CATEGORY 4:   NON-INVESTMENT GRADE
    Duff 4           Speculative  investment characteristics. Liquidity is not sufficient to
                      insure against  disruption  in  debt service.  Operating  factors  and
                      market access may be subject to a high degree of variation.
 
    E. CATEGORY 5:   DEFAULT
    Duff 5           Issuer failed to meet scheduled principal and/or interest payments.

Item 27.  INDEMNIFICATION

     Pursuant to Section 5.3 of the Registrant's Declaration of 
Trust and under Section 4.8 of the Registrant's By-Laws, the
indemnification of the Registrant's trustees, officers, employees and
agents is permitted if it is determined that they acted under the
belief that their actions were in or not opposed to the best interest
of the Registrant, and, with respect to any criminal proceeding, they
had reasonable cause to believe their conduct was not unlawful.  In
addition, indemnification is permitted only if it is determined that
the actions in question did not render them liable by reason of
willful misfeasance, bad faith or gross negligence in the performance
of their duties or by reason of reckless disregard of their
obligations and duties to the Registrant.  Trustees, officers,
employees and agents will be indemnified for the expense of litigation
if it is determined that they are entitled to indemnification against
any liability established in such litigation.  The Registrant may also
advance money for these expenses provided that they give their
undertakings to repay the Registrant unless their conduct is later
determined to permit indemnification.
   
          Pursuant to Section 5.2 of the Registrant's Declaration of
Trust and paragraph 8 of the Registrant's Investment Management Agreement,
neither the Investment Manager nor any trustee, officer, employee or
agent of the Registrant shall be liable for any action or failure to
act, except in the case of bad faith, willful misfeasance, gross
negligence or reckless disregard of duties to the Registrant.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to trustees,
officers and controlling persons of the Registrant pursuant to the
foregoing provisions or otherwise, the  Registrant has been advised
that in the opinion of the  Securities and Exchange Commission such
indemnification is

                                     2
<PAGE>

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

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

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

                         AMENDMENT TO CUSTODY AGREEMENT


     Amendment made as of this 17th day of April, 1996 by and between Dean 
Witter Short-Term Bond Fund (the "Fund") and The Bank of New York (the 
"Custodian") to the  Custody Agreement between the Fund and the Custodian 
dated December 21, 1993 (the "Custody Agreement").  The Custody Agreement is 
hereby amended as follows: 

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

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

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

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

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