and                 subsidiary, Dean Witter Services Company Inc., serve in various investment management, advisory, management and
Sub-Advisor         administrative capacities to 100 investment companies and other portfolios with assets of approximately $91.1
                    billion at November 30, 1996. BlackRock Financial Management, Inc. (the "Sub-Advisor") has been retained by the
                    Investment Manager to provide investment advice and manage the Fund's portfolio. The Sub-Advisor currently

                    receives a monthly fee from the Investment Manager equal to 40% of the Investment Manager's monthly fee (see

                    at the annual rate of 0.20 of 1% of average daily net assets of the Fund (see page 19). The Distributor also
                    receives a sales charge of 3% of the offering price.
- ------------------------------------------------------------------------------------------------------------------------------------
Special Risk        The net asset value of the Fund's shares will fluctuate with changes in the market value of its portfolio
Considerations      securities. Mortgage-backed and asset-backed securities have different characteristics than traditional debt
                    securities, primarily in that interest and principal payments are made more frequently, usually monthly, and
                    that principal may be prepaid at any time (see page 7). Mortgage-backed and asset-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 prepayment risks. The types of mortgage-backed securities in
                    which the Fund may invest include derivative products such as collateralized mortgage obligations and stripped
                    mortgage-backed securities, which are highly sensitive to changes in prepayment and interest rates and have
                    special characteristics and risks (see pages 7 and 10). Asset-backed securities involve certain risks 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 (see page 10). In addition, the
                    Fund may utilize certain investment techniques, including options and futures for hedging purposes, and the use
                    of leverage, including reverse repurchase agreements and dollar rolls, which entail additional risks (see pages
                    11-15).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean  Witter Premier Income  Trust (the "Fund")  is an open-end, diversified
management investment company. The Fund is a trust of the type commonly known as
a  "Massachusetts  business  trust"  and   was  organized  under  the  laws   of
Massachusetts on March 27, 1991.
 
    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 one hundred  investment companies, thirty of which
are listed  on  the New  York  Stock Exchange,  with  combined total  assets  of
approximately  $88 billion  at November  30, 1996.  The Investment  Manager also
manages  and  advises  portfolios  of  pension  plans,  other  institutions  and
individuals which aggregated approximately $3.1 billion at such date.
    
 
    The  Fund  has retained  the  Investment Manager  to  provide administrative
services, manage its business affairs and supervise the investment of the Fund's
assets. InterCapital has retained Dean  Witter Services Company Inc. to  perform
the aforementioned administrative services for the Fund.
 
    Under  a Sub-Advisory Agreement between BlackRock Financial Management, Inc.
(the "Sub-Advisor") and  the Investment  Manager, the  Sub-Advisor provides  the
Fund  with investment  advice and  portfolio management  relating to  the Fund's
investments in portfolio securities, subject  to the overall supervision of  the
Investment  Manager. The Fund's Trustees review the various services provided by
or under the direction of the  Investment Manager and the Sub-Advisor 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.
 
   
    The Sub-Advisor, whose address is 345 Park Avenue, New York, New York 10154,
is a Delaware limited partnership organized in April, 1988 by Laurence D.  Fink,
Ralph  L. Schlosstein and The Blackstone  Group (a private investment bank). The
Sub-Advisor's general partners are Messrs.  Fink and Schlosstein and  Blackstone
Financial  Management Inc. (all the  stock of which is  owned by partners of The
Blackstone Group). The Sub-Advisor serves as investment adviser to  fixed-income
investors in the U.S. and overseas with combined assets in excess of $43 billion
as of November 30, 1996.
    
 
    On  June 16, 1994, the partners of the Sub-Advisor entered into a definitive
agreement to sell their  partnership interests in the  Sub-Advisor to PNC  Bank,
N.A. ("PNC"), headquartered in Pittsburgh, Pennsylvania (the "Transaction"). The
Transaction,  which was subject to bank  regulatory approval, closed on February
28, 1995  and  was  subject  to various  conditions,  including  the  following:
BlackRock  will retain its name and will continue to operate out of its New York
office. All members of the Sub-Advisor's  senior management team agreed to  sign
long-term  employment contracts and  be responsible for  managing the day-to-day
affairs of  the  Sub-Advisor. Following  the  closing of  the  Transaction,  the
Sub-Advisor  became a wholly owned corporate  subsidiary of PNC Asset Management
Group, Inc., the holding company for PNC's asset management business.
 
    PNC is a commercial bank offering a wide range of domestic and international
commercial banking,  retail banking  and trust  services to  its customers.  Its
principal office is located in Pittsburgh, Pennsylvania.
 
                                       5
<PAGE>
    PNC  is a wholly-owned  indirect subsidiary of PNC  Bank Corp. (the "Holding
Company"), a bank holding company organized  under the laws of the  Commonwealth
of Pennsylvania.
 
    In order to assure continuity of investment advisory services to the Fund by
the  Sub-Advisor after the Transaction,  the Board met in  person on October 20,
1994, for the purpose of considering whether  it would be in the best  interests
of  the  Fund  and  its  shareholders  for  InterCapital  to  enter  into  a new
sub-advisory  agreement  with   the  Sub-Advisor   (the  "current   Sub-Advisory
Agreement") to take effect upon consummation of the Transaction. At its meeting,
the  Board, including each of  the Trustees who are  not "interested persons" of
the Fund, as that term is defined in the 1940 Act (the "Independent  Trustees"),
unanimously  approved the current Sub-Advisory  Agreement and recommended it for
approval by Shareholders. The current Sub-Advisory Agreement is identical to the
former Sub-Advisory  Agreement except  for  the effective  date and  the  stated
expiration date. At the meeting of Shareholders which took place on February 17,
1995, the Shareholders voted to approve the current Sub-Advisory Agreement which
became effective on February 28, 1995.
 
    As  full compensation for the services  and facilities furnished to the Fund
and for expenses of the  Fund assumed by the  Investment Manager, the Fund  pays
the  Investment Manager  monthly compensation  calculated daily  by applying the
annual rate of 0.50% to the Fund's net assets. As compensation for its  services
provided pursuant to the Sub-Advisory Agreement, the Investment Manager pays the
Sub-Advisor monthly compensation equal to 40% of its monthly compensation.
 
   
    For  the  fiscal  year  ended  October  31,  1996,  the  Fund  accrued total
compensation to the Investment Manager amounting to 0.50% of the Fund's  average
daily  net assets (of which 40% was accrued to the Sub-Advisor by the Investment
Manager) and the Fund's total expenses  amounted to 3.10% of the Fund's  average
daily net assets.
    
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The  investment objective  of the Fund  is to  earn a high  level of current
income consistent  with  low  volatility of  principal.  The  Fund's  investment
objective  is a  fundamental policy and  may not be  changed without shareholder
approval. There  is  no assurance  that  the  objective will  be  achieved.  The
following  policies may be changed by  the Board of Trustees without shareholder
approval.
 
    The Fund seeks to achieve its investment objective by investing under normal
circumstances at least 65% of its total assets in (i) fixed rate and  adjustable
rate   mortgage-backed  securities   ("Mortgage-Backed  Securities")   and  (ii)
securities backed by other assets, such as automobile or credit card receivables
and home equity loans ("Asset-Backed  Securities"). The Fund will only  purchase
Mortgage-Backed  Securities  and  Asset-Backed Securities  which  are  issued or
guaranteed by the United States Government, its agencies or instrumentalities or
are rated Aaa by Moody's Investors Service, Inc. ("Moody's") or AAA by  Standard
&  Poor's Corporation ("S&P") or,  if not rated, determined  to be of comparable
quality by the Investment Manager and  the Sub-Advisor. (Currently there are  no
Asset-Backed  Securities issued or  guaranteed by the  United States Government,
its  agencies  or  instrumentalities.)  The  Fund  expects  that  under   normal
circumstances the market value dollar weighted average life (or period until the
next reset date) of the Fund's portfolio securities will be no greater than five
years.
 
    The  Fund  seeks to  achieve low  volatility by  investing in  a diversified
portfolio of securities which the Investment Manager and the Sub-Advisor believe
will, in  the aggregate,  be  resistant to  significant fluctuations  in  market
value.  The Investment Manager and Sub-Advisor  believe that the Fund's policies
of purchasing shorter term Mortgage-
 
                                       6
<PAGE>
Backed and Asset-Backed Securities will reduce the volatility of the Fund's  net
asset  value over the long term.  Although the values of fixed-income securities
generally increase  during  periods of  declining  interest rates  and  decrease
during  periods of increasing  interest rates, the  extent of these fluctuations
has historically  generally been  smaller  for short  term securities  than  for
securities with longer maturities. Conversely, the yield available on short term
securities has also historically been lower on average than those available from
longer term securities.
 
    While   the  Fund  invests  primarily   in  Mortgage-Backed  Securities  and
Asset-Backed Securities, under ordinary circumstances it may invest up to 35% of
its total assets in (i) U.S. Government securities (securities guaranteed as  to
principal   and   interest   by   the  United   States   or   its   agencies  or
instrumentalities), (ii) corporate  debt securities,  including adjustable  rate
securities,  rated Aaa by Moody's or AAA by S&P or, if unrated, determined to be
of comparable quality by the Fund's Trustees, (iii) with respect to up to 5%  of
the  Fund's  total assets,  high  quality municipal  securities,  including zero
coupon securities, with  the highest  rating by Moody's  or S&P,  or (iv)  money
market  instruments. U.S.  Government securities  in which  the Fund  may invest
include Treasury bills, notes and bonds, including zero coupon securities. Money
market instruments  in  which the  Fund  may  invest are  securities  issued  or
guaranteed  by the U.S.  Government (Treasury bills,  notes and bonds, including
zero coupon securities); bank  obligations; Eurodollar certificates of  deposit;
obligations  of savings institutions; fully insured certificates of deposit; and
commercial paper rated within the  two highest grades by  Moody's or S&P or,  if
not rated, issued by a company having an outstanding debt issue rated AAA by S&P
or Aaa by Moody's.
 
    In an effort to increase investment return or to hedge the Fund's portfolio,
the  Fund  may  engage  in  various  investment  techniques,  including  reverse
repurchase agreements,  dollar  rolls,  purchasing  and  selling  call  and  put
options,  entering  into interest  rate futures  contracts and  related options,
purchasing securities on a when-issued,  delayed delivery or forward  commitment
basis and lending portfolio securities (see "Other Investment Policies" below).
 
    There  may be periods during which, in the opinion of the Investment Manager
and the Sub-Advisor, market conditions warrant  reduction of some or all of  the
Fund's  securities holdings. During such periods, the Fund may adopt a temporary
"defensive" posture in which greater than  35% of its total assets are  invested
in U.S. Government securities, money market instruments or cash.
 
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.
 
    The Fund  will  invest  in  mortgage  pass-through  securities  representing
participation interests in
 
                                       7
<PAGE>
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  mortgage pass-through securities  in which the  Fund may invest include
those issued or guaranteed by GNMA, FNMA and FHLMC. GNMA certificates are direct
obligations of the U.S. Government and, as  such, are backed by the "full  faith
and credit" of the United States. FNMA is a federally chartered, privately owned
corporation  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. Each of GNMA, FNMA and FHLMC guarantee timely  distribution
of  interest  to  certificate  holders.  GNMA  and  FNMA  also  guarantee timely
distribution of scheduled  principal payments. FHLMC  generally guarantees  only
the ultimate collection of principal of the underlying mortgage loans.
 
    Certificates  for  Mortgage-Backed  Securities  evidence  an  interest  in a
specific pool of  mortgages. These  certificates are, in  most cases,  "modified
pass-through"  instruments, wherein the issuing agency guarantees the payment of
principal and interest on mortgages underlying the certificates, whether or  not
such amounts are collected by the issuer on the underlying mortgages.
 
    ADJUSTABLE RATE MORTGAGE SECURITIES.  The Fund may also invest in adjustable
rate  mortgage securities  ("ARMs"), which are  pass-through mortgage securities
collateralized by  mortgages  with  adjustable rather  than  fixed  rates.  ARMs
eligible  for inclusion in a mortgage pool generally provide for a fixed initial
mortgage interest  rate for  either the  first three,  six, twelve  or  thirteen
scheduled  monthly  payments.  Thereafter,  the interest  rates  are  subject to
periodic adjustment based on changes to a designated benchmark index.
 
    ARMs contain maximum and  minimum rates beyond  which the mortgage  interest
rate  may not vary over the lifetime  of the security. In addition, certain ARMs
provide for additional limitations on the  maximum amount by which the  mortgage
interest  rate  may  adjust  for any  single  adjustment  period. Alternatively,
certain ARMs contain limitations on changes in the required monthly payment.  In
the  event that a monthly payment is not sufficient to pay the interest accruing
on an ARM, any  such excess interest  is added to the  principal balance of  the
mortgage  loan, which is repaid through  future monthly payments. If the monthly
payment for such an instrument  exceeds the sum of  the interest accrued at  the
applicable  mortgage interest  rate and the  principal payment  required at such
point to amortize the outstanding principal  balance over the remaining term  of
the  loan,  the excess  is  utilized to  reduce  the then  outstanding principal
balance of the ARM.
 
    PRIVATE MORTGAGE  PASS-THROUGH  SECURITIES.  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
 
                                       8
<PAGE>
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.  Types  of credit  enhancements  are described  under "Asset-Backed
Securities" below.
 
    COLLATERALIZED   MORTGAGE    OBLIGATIONS   AND    MULTICLASS    PASS-THROUGH
SECURITIES.   Collateralized mortgage obligations or "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  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  mortgages secured by  an interest in real
property. REMICs are  similar to  CMOs in that  they issue  multiple classes  of
securities,  but  unlike  CMOs, which  are  required  to be  structured  as debt
securities, REMICs  may be  structured as  indirect ownership  interests in  the
underlying assets of the REMICs themselves. However, there are no effects on the
Fund  from investing in CMOs issued by  entities that have elected to be treated
as REMICs, and all  future references to  CMOs shall also  be deemed to  include
REMICs.
 
    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, which
may  include  Stripped Mortgage-Backed  Securities  as described  below,  may be
higher than prevailing market yields on Mortgage-Backed Securities with  similar
maturities.  As a result of the uncertainty of the cash flows of these tranches,
the market prices of and yield on these tranches tend to be more volatile.
 
    The Fund  also may  invest in,  among other  things, parallel  pay CMOs  and
Planned  Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured
to provide payments of principal  on each payment date  to more than one  class.
These simultaneous payments are taken into account in
 
                                       9
<PAGE>
calculating  the stated maturity date or  final distribution date of each class,
which, as with other CMO structures, must be retired by its stated maturity date
or final  distribution date  but may  be retired  earlier. PAC  Bonds  generally
require  payments of a specified  amount of principal on  each payment date. PAC
Bonds always are parallel pay CMOs  with the required principal payment on  such
securities  having  the highest  priority after  interest has  been paid  to all
classes.
 
    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.
 
    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  Securities
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  will 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 Aaa by Moody's or AAA by S&P.
 
    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
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. Stripped  Mortgage-Backed
Securities  issued by the U.S. Government or  its agencies, and which are backed
by fixed-rate  mortgages,  will  be  treated as  liquid  provided  they  are  so
determined  by, or under procedures approved by, the Board of Trustees. The Fund
may not invest more than 10% of its net assets in illiquid securities.
 
ASSET-BACKED SECURITIES
 
    The securitization techniques used to develop Mortgage-Backed Securities are
also 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.
 
    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
 
                                       10
<PAGE>
investment objective and policies and applicable regulatory requirements.
 
    TYPES  OF CREDIT  ENHANCEMENT.  Mortgage-Backed  Securities and Asset-Backed
Securities are often backed by a pool of assets representing the obligations  of
a  number of different parties. To lessen  the effect of failures by obligors on
underlying assets to  make payments,  those securities may  contain elements  of
credit  support, which  fall into two  categories: (i)  liquidity protection and
(ii) protection against losses resulting from ultimate default by an obligor  on
the underlying assets. Liquidity protection refers to the provision of advances,
generally  by the entity  administering the pool  of assets, to  ensure that the
receipt of  payments  on  the  underlying  pool  occurs  in  a  timely  fashion.
Protection against losses resulting from default ensures ultimate payment of the
obligations on at least a portion of the assets in the pool. This protection may
be provided through guarantees, insurance policies or letters of credit obtained
by  the  issuer  or  sponsor  from  third  parties,  through  various  means  of
structuring the transaction  or through  a combination of  such approaches.  The
degree  of  credit  support  provided  for  each  issue  is  generally  based on
historical information respecting the level  of credit risk associated with  the
underlying  assets. Delinquencies or losses in excess of those anticipated could
adversely affect the return on  an investment in a  security. The Fund will  not
pay  any fees for credit  support, although the existence  of credit support may
increase the price of a security.
 
OTHER INVESTMENT POLICIES
 
    REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which
may be viewed  as a type  of secured lending  by the Fund,  and which  typically
involve the acquisition by the Fund of debt securities, from a selling financial
institution  such as a bank, savings  and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security at a specified price and at
a fixed time in the  future, usually not more than  seven days from the date  of
purchase.  While repurchase agreements involve certain risks not associated with
direct investments  in  debt  securities,  including the  risks  of  default  or
bankruptcy  of the  selling financial  institution, the  Fund follows procedures
designed to minimize such risks.  These procedures include effecting  repurchase
transactions  only with  large, well-capitalized  and well-established financial
institutions and maintaining adequate collateralization.
 
    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.
 
    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. An increase in  the
percentage  of the Fund's  assets committed to  the purchase of  securities on a
 
                                       11
<PAGE>
when-issued, delayed  delivery  or forward  commitment  basis may  increase  the
volatility  of the Fund's net asset value.  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 when-issued or delayed delivery securities and forward
commitments. The Fund's ability to enter into such transactions is not otherwise
limited, but the Fund expects that  under normal circumstances no more than  15%
of the Fund's total assets will be so invested.
 
    WHEN,  AS AND IF ISSUED  SECURITIES.  The Fund  may purchase securities on a
"when, as and if issued" basis under which the issuance of the security  depends
upon  the  occurrence of  a  subsequent event,  such  as approval  of  a merger,
corporate reorganization,  leveraged  buy-out  or  debt  restructuring.  If  the
anticipated  event does not  occur and the  securities are not  issued, the Fund
will have lost an investment opportunity.  An increase in the percentage of  the
Fund's  assets committed  to the purchase  of securities  on a "when,  as and if
issued" basis may increase the volatility of  its net asset value. The Fund  may
also  sell securities  on a  "when, as  and if  issued" basis  provided that the
issuance of a security will result automatically from the exchange or conversion
of a security owned by the Fund at the time of sale.
 
    LENDING OF  PORTFOLIO SECURITIES.    Consistent with  applicable  regulatory
requirements, the Fund may lend its portfolio securities to brokers, dealers and
other  financial institutions, provided that such loans are callable at any time
by the Fund (subject to certain notice provisions described in the Statement  of
Additional  Information), and are at all  times secured by cash, U.S. Government
securities or  other high  grade  debt securities,  which  are maintained  in  a
segregated  account pursuant  to applicable  regulations and  that are  at least
equal to the market value, determined daily, of the loaned securities.
 
    PRIVATE PLACEMENTS.  The Fund may invest in securities which are subject  to
restrictions  on  resale  because  they  have  not  been  registered  under  the
Securities Act  of  1933,  as  amended (the  "Securities  Act"),  or  which  are
otherwise  not readily marketable. These securities are generally referred to as
private placements or restricted securities.  Limitations on the resale of  such
securities  may have an  adverse effect on their  marketability, and may prevent
the Fund from disposing of them promptly at reasonable prices. The Fund may have
to bear the expense of  registering such securities for  resale and the risk  of
substantial delays in effecting such registration.
 
   
    The  Securities  and Exchange  Commission has  adopted  Rule 144A  under the
Securities Act,  which  permits  the  Fund  to  sell  restricted  securities  to
qualified  institutional buyers  without limitation. The  Investment Manager and
Sub-Adviser pursuant to  procedures adopted by  the Trustees of  the Fund,  will
make  a determination as to the  liquidity of each restricted security purchased
by the  Fund.  If a  restricted  security is  determined  to be  "liquid,"  such
security  will not be included within  the category "illiquid securities," which
is limited by  the Fund's  investment restrictions to  10% of  the Fund's  total
assets.  Investing in Rule  144A securities could have  the effect of increasing
the level of Fund illiquidity to the extent the Fund, at a particular time,  may
be  unable to find qualified institutional  buyers interested in purchasing such
securities.
    
 
    OPTIONS AND FUTURES TRANSACTIONS.  The Fund is permitted to enter into  call
and  put options  on U.S. Treasury  notes, bonds  and bills which  are listed on
Exchanges and written in  over-the-counter transactions ("OTC options").  Listed
options  are issued by the Options Clearing Corporation ("OCC"). OTC options are
purchased from or sold (written) to dealers or financial institutions which have
entered into direct agreements with the  Fund. The Fund may purchase listed  and
over-the-counter  call  and  put  options  on  U.S.  Government  securities  and
Mortgage-Backed Securities in amounts  equalling up to 5%  of its total  assets.
The  Fund may purchase call and put options on securities which it holds (or has
the right to acquire) in its portfolio only for hedging purposes.
 
                                       12
<PAGE>
    The  Fund  may  also  purchase  and  sell  interest  rate  futures contracts
("futures contracts")  that  are traded  on  U.S. commodity  exchanges  on  such
underlying  securities  as  U.S.  Treasury bonds,  notes  and  bills, Eurodollar
instruments and  Mortgage-Backed  Securities. The  Fund  will purchase  or  sell
futures  contracts only for the purpose of hedging its portfolio (or anticipated
portfolio) securities against changes in prevailing interest rates, and not  for
speculative purposes.
 
    The  Fund may also purchase call and  put options on futures contracts which
are traded on an  Exchange and enter into  closing transactions with respect  to
such options to terminate an existing position.
 
RISK CONSIDERATIONS
 
    The  net asset value of the Fund's shares will fluctuate with changes in the
market value of the Fund's portfolio securities. The market value of the  Fund's
portfolio  securities will  increase or decrease  due to a  variety of economic,
market and political factors which cannot be predicted, in particular  movements
in  interest rates  and, with respect  to foreign  currencies, currency exchange
rates. A decline in prevailing interest  rates generally increases the value  of
fixed-income securities, while an increase in rates usually reduces the value of
those  securities. (The Fund's  yield also will  vary based on  the yield of the
Fund's portfolio securities.)
 
    MORTGAGE-BACKED  AND   ASSET-BACKED   SECURITIES.      Mortgage-Backed   and
Asset-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 and  the Sub-Advisor  will seek  to manage  these risks  (and  potential
benefits)  by  investing in  a variety  of such  securities and  through hedging
techniques.
 
    Mortgage-Backed Securities  and  Asset-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 and Asset-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.  Asset-Backed
Securities,  although less  likely to  experience the  same prepayment  rates as
Mortgage-Backed  Securities,  may  respond  to  certain  of  the  same   factors
influencing prepayments, while at other times different factors, such as changes
in  credit use  and payment patterns  resulting from social,  legal and economic
factors,  will   predominate.   Mortgage-Backed  Securities   and   Asset-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.
 
                                       13
<PAGE>
    The  Fund may  invest in mortgage  derivative securities, such  as CMOs, the
average life of which is  determined using mathematical models that  incorporate
prepayment  assumptions  and  other  factors that  involve  estimates  of future
economic and  market conditions.  These estimates  may vary  from actual  future
results,  particularly during periods of extreme market volatility. In addition,
under certain  market conditions,  such as  those that  developed in  1995,  the
average  weighted  life of  mortgage  derivative securities  may  not accurately
reflect the price  volatility of  such securities.  For example,  in periods  of
supply and demand imbalances in the market for such securities and/or in periods
of  sharp interest rate movements, the  prices of mortgage derivative securities
may fluctuate to  a greater  extent than would  be expected  from interest  rate
movements alone.
 
    The  Fund's investments in  mortgage derivative securities  also subject the
Fund to extension risk. Extension risk  is the possibility that rising  interest
rates  may  cause prepayments  to occur  at  a slower  than expected  rate. This
particular risk may effectively change a security which was considered short  or
intermediate-term  at the time of purchase  into a long-term security. Long-term
securities generally fluctuate more  widely in response  to changes in  interest
rates than short or intermediate-term securities.
 
    There  are certain risks  associated specifically with  CMOs. CMOs issued by
private entities are not  U.S. Government securities and  are not guaranteed  by
any  government agency, although the securities  underlying a CMO may be subject
to a guarantee. Therefore, if  the collateral securing the  CMO, as well as  any
third  party credit support or guarantees,  is insufficient to make payment, the
holder could sustain a loss. However, as stated above, the Fund will invest only
in CMOs  which are  rated AAA  by S&P  or Aaa  by Moody's  or, if  unrated,  are
determined  to be  of comparable quality.  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.
 
    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, 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  from  repossessed  collateral  may  not  always be
sufficient to support payments on these securities.
 
    STRIPPED MORTGAGE-BACKED SECURITIES.  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 Aaa by Moody's or AAA by S&P.
 
    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
understands  that the staff of the  Securities and Exchange Commission 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. Stripped Mortgage-Backed Securities issued by
the U.S. Government or its
 
                                       14
<PAGE>
agencies,  and  which are  backed by  fixed-rate mortgages,  will be  treated as
liquid provided they are so determined by, or under procedures approved by,  the
Board  of Trustees. The Fund may not invest more than 10% of its total assets in
illiquid securities (see "Investment Restrictions" below).
 
    ZERO COUPON SECURITIES.  A portion of the fixed-income securities  purchased
by  the Fund may be  zero coupon securities. Such  securities are purchased at a
discount from their face amount, giving the purchaser the right to receive their
full value at maturity. The interest  earned on such securities is,  implicitly,
automatically  compounded and paid out at  maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest if  prevailing interest  rates  decline, the  owner  of a  zero  coupon
security  will be  unable to  particpate in  higher yields  upon reinvestment of
interest received  on interest-paying  securities if  prevailing interest  rates
rise.
 
    A  zero coupon  security pays  no interest  to its  holder during  its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will not
receive current cash  available for distribution  to shareholders. In  addition,
zero  coupon securities are subject  to substantially greater price fluctuations
during periods  of  changing  prevailing  interest  rates  than  are  comparable
securities  which  pay interest  on  a current  basis.  Current federal  tax law
requires that a holder  (such as the  Fund) of a zero  coupon security accrue  a
portion  of the discount at which the security was purchased as income each year
even though  the Fund  receives no  interest payments  in cash  on the  security
during the year.
 
   
    REVERSE  REPURCHASE AGREEMENTS AND DOLLAR ROLLS.   The Fund will establish a
segregated account with its custodian bank in which it will maintain cash,  U.S.
Government securities or other liquid portfolio securities equal in value to its
obligations  in  respect  of  reverse repurchase  agreements  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  the  proceeds of  the agreement  may  be
restricted  pending  a  determination by  the  other  party, or  its  trustee or
receiver, whether to enforce the Fund's obligation to repurchase the securities.
    
 
    Reverse repurchase agreements  and dollar rolls  are speculative  techniques
involving leverage, and are considered borrowings by the Fund. The Fund does not
expect  to engage in reverse repurchase agreements and dollar rolls with respect
to greater than 25% of the Fund's total assets.
 
    OPTIONS AND FUTURES TRANSACTIONS.  Exchanges may limit  the amount by  which
the  price of a futures contract  may move on any day.  If the price moves equal
the daily limit on successive days, then it may prove impossible to liquidate  a
futures position until the daily limit moves have ceased.
 
    Participation  in the options  or futures markets  involves investment risks
and transaction costs to which the Fund  would not be subject absent the use  of
these  strategies. If  the Investment  Manager's or  Sub-Advisors' prediction of
movements in the direction of the securities, currency or interest rate  markets
are  inaccurate, the adverse consequences to the  Fund (e.g., a reduction in the
Fund's net asset  value or a  reduction in  the amount of  income available  for
distribution)  may leave the  Fund in a  worse position than  if such strategies
were not  used.  Risks  inherent  in  the  use  of  options,  futures  contracts
and  options  on  futures contracts  include  (a) dependence  on  the Investment
Manager's or  Sub-Advisors'  ability  to  predict  correctly  movements  in  the
direction  of interest rates, as well as securities and/or currency markets; (b)
imperfect correlation between  the price  of options and  futures contracts  and
options  thereon and  movements in  the prices  of the  securities or currencies
being hedged;  (c) the  fact that  skills  needed to  use these  strategies  are
different from those needed to select
 
                                       15
<PAGE>
portfolio  securities; (d) the possible absence of a liquid secondary market for
any particular  instrument at  any time;  and  (e) the  possible need  to  defer
closing out certain hedged positions to avoid adverse tax consequences.
 
    Another  such risk is that the price of the futures contract may not move in
tandem with the change in prevailing interest rates against which the Fund seeks
a hedge. A correlation may 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. See the Statement of Additional Information for further discussion  of
such risks.
 
    New  futures  contracts, options  and other  financial products  and various
combinations thereof continue to be developed.  The Fund may invest in any  such
futures,  options or products as may be developed, to the extent consistent with
its investment objective and applicable regulatory requirements.
 
    For additional risk  disclosure, please refer  to the "Investment  Objective
and  Policies" and "Portfolio Characteristics" sections of the Prospectus and to
the "Investment Practices and Policies"  section of the Statement of  Additional
Information.
 
PORTFOLIO MANAGEMENT
 
    The  Fund's portfolio is actively managed  by its Investment Manager and the
Sub-Advisor with  a view  to achieving  the Fund's  investment objective.  As  a
result  of the Fund's investment  objective and policies, and  the nature of the
Mortgage-Backed Securities  and  Asset-Backed  Securities  markets,  the  Fund's
portfolio  turnover rate may exceed 200%. Short-term gains and losses may result
from such portfolio transactions. See "Dividends, Distributions and Taxes" for a
discussion of the tax implications of the Fund's trading policy.
 
   
    In determining which  securities to  purchase for the  Fund or  hold in  the
Fund's  portfolio,  the  Investment Manager  and  the Sub-Advisor  will  rely on
information from various sources, including research, analysis and appraisals of
brokers  and  dealers,   including  Dean   Witter  Reynolds   Inc.  ("DWR"),   a
broker-dealer  affiliate of InterCapital; the views  of Trustees of the Fund and
others regarding  economic  developments  and  interest  rate  trends;  and  the
Investment  Manager's  and  Sub-Advisor's  own  analysis  of  factors  they deem
relevant. The Fund  is part of  the Dean Witter  family of mutual  funds and  is
managed  by  its  Investment  Manager,  InterCapital,  and  by  its Sub-Advisor,
BlackRock Financial Management, Inc. ("BlackRock"). BlackRock manages in  excess
of  $43 billion of  assets on behalf of  individual and institutional investors,
including 21 closed-end funds  traded on either the  New York or American  Stock
Exchanges, several open-end funds, and separate accounts. Along with BlackRock's
portfolio  management team,  Scott Amero has  been the  Fund's primary portfolio
manager since its inception. Mr. Amero is a Managing Director of BlackRock and a
member of its Investment Strategy Committee, and is a specialist in the mortgage
and  short  duration  sectors.  His  areas  of  expertise  include  asset-backed
securities,  adjustable  rate  mortgage  securities  and  other  short  duration
mortgage products. Prior  to joining  BlackRock in 1990,  Mr. Amero  was a  Vice
President  in Fixed  Income Research at  The First Boston  Corporation, where he
became the firm's primary strategist for short duration securities.
    
 
    Brokerage commissions are not  normally charged on the  purchase or sale  of
Mortgage-Backed  Securities or U.S. Government securities, but such transactions
generally involve costs  in the form  of spreads between  bid and asked  prices.
Orders  for transactions in portfolio securities are  placed for the Fund with a
number of brokers and dealers,  which may include DWR.  Pursuant to an order  of
the   Securities  and  Exchange  Commission,   the  Fund  may  effect  principal
transactions in certain money market instruments with DWR. In addition, the Fund
may incur brokerage commissions on transactions conducted through DWR.

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.  With respect 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. Purchase more  than 10% of  all outstanding voting  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,  except that the Fund will  invest at least 25%  of
its  assets in Mortgage-Backed  and Asset-Backed Securities  under normal market
conditions. This restriction does not apply to obligations issued or  guaranteed
by the United States Government or its agencies or instrumentalities.
 
   4.  Invest more  than 10%  of its total  assets in  "illiquid securities" and
repurchase agreements which have a maturity of longer than seven days. The staff
of the  Securities and  Exchange  Commission has  taken  the position  that  OTC
options are illiquid securities. The Investment Manager and Sub-Advisor disagree
with  this position. Nevertheless, the  Fund has agreed to  treat OTC options as
illiquid securities for purposes of this  investment restriction so long as  the
staff maintains such position.
 
   5.  Invest more  than 5% of  the value of  its total assets  in securities of
issuers having a record, together with predecessors, of less than three years of
continuous operation.  This  restriction  shall  not  apply  to  Mortgage-Backed
Securities  or Asset-Backed Securities or to any obligation of the United States
Government, its agencies or instrumentalities.
 
   6. Purchase or sell commodities or commodities contracts except that the Fund
may purchase  and  sell interest  rate  futures contracts  and  related  options
thereon.
 
   7.  Pledge its assets or  assign or otherwise encumber  them except to secure
permitted  borrowings.  (For  the   purpose  of  this  restriction,   collateral
arrangements  with respect  to initial or  variation margin for  futures are not
deemed to be pledges of assets.)
 
   8. Purchase securities on margin (but the Fund may obtain short-term loans as
are necessary for the clearance of transactions). The deposit or payment by  the
Fund  of initial  or variation  margin in  connection with  futures contracts or
related options thereon is not considered the purchase of a security on margin.
 
   9. Borrow money in excess  of 33 1/3% of  the Fund's total assets  (including
the proceeds of the borrowings).
 
    If  a percentage restriction is adhered to at the time of investment (except
in the  case of  Restriction 9),  a  later increase  or decrease  in  percentage
resulting  from a change in values of portfolio securities or amount of total or
net assets  will  not  be  considered  a  violation  of  any  of  the  foregoing
restrictions.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    The  Fund offers its  shares for sale  to the public  on a continuous basis.
Shares of  the  Fund are  distributed  by  Dean Witter  Distributors  Inc.  (the
"Distributor"),   an  affiliate  of  the   Investment  Manager,  pursuant  to  a
Distribution Agreement between the Fund and  the Distributor and offered by  DWR
and
 
                                       17
<PAGE>
other  dealers  who  have  entered  into  selected  dealer  agreements  with the
Distributor ("Selected Broker-Dealers"). The  principal executive office of  the
Distributor is located at Two World Trade Center, New York, New York 10048.
 
    The minimum initial purchase is $1,000. Subsequent purchases of $100 or more
may  be made by  sending a check,  payable to Dean  Witter Premier Income Trust,
directly to Dean Witter Trust Company  (the "Transfer Agent") at P.O. Box  1040,
Jersey  City, NJ  07303 or by  contacting an  account executive of  DWR or other
Selected Broker-Dealer. The minimum initial purchase in the case of  investments
through  EasyInvestSM, an automatic purchase  plan (see "Shareholder Services"),
is $100, provided  that the  schedule of  automatic investments  will result  in
investments  totalling at  least $1,000 within  the first twelve  months. In the
case of investments  pursuant to systematic  payroll deduction plans  (including
individual   retirement  plans),  the  Fund,   in  its  discretion,  may  accept
investments without  regard to  any  minimum amounts  which would  otherwise  be
required  if the  Fund has  reason to  believe that  additional investments will
increase the investment  in all accounts  under such plans  to at least  $1,000.
Certificates for shares purchased will not be issued unless a request is made by
the shareholder in writing to the Transfer Agent. The offering price will be the
net  asset value per  share next determined  following receipt of  an order (see
"Determination of Net Asset Value" below),  plus a sales charge (expressed as  a
percentage  of  the offering  price) on  a  single transaction  as shown  in the
following table:

    The above schedule of sales charges  is applicable to purchases in a  single
transaction  by, among others: (a) an individual;  (b) an individual, his or her
spouse and their children under the age  of 21 purchasing shares for his or  her
own  accounts; (c) a trustee  or other fiduciary purchasing  shares for a single
trust estate or  a single fiduciary  account; (d) a  pension, profit-sharing  or
other  employee benefit plan qualified or non-qualified under Section 401 of the
Internal Revenue  Code;  (e)  tax-exempt  organizations  enumerated  in  Section
501(c)(3)  or  (13) of  the Internal  Revenue Code;  (f) employee  benefit plans
qualified under Section 401 of the Internal Revenue Code of a single employer or
of employers who are  "affiliated persons" of each  other within the meaning  of
Section  2(a)(3)(c)  of the  Act and  for  investments in  Individual Retirement
Accounts of employees of a single employer through Systematic Payroll  Deduction
Plans, or (g) any other organized group of persons, whether incorporated or not,
provided  the organization has been in existence for at least six months and has
some purpose other than  the purchase of redeemable  securities of a  registered
investment company at a discount.
 
    Shares  of  the Fund  are sold  through  the Distributor  on a  normal three
business day settlement basis; that is, payment is due on the third business day
(settlement date) after the order is placed with the Distributor. Shares of  the
Fund  purchased through the  Distributor are entitled  to any dividends declared
beginning on the  next business  day following  settlement date.  Since DWR  and
other  Selected Broker-Dealers forward investors' funds on settlement date, they
will benefit  from the  temporary use  of the  funds if  payment is  made  prior
thereto.  Shares  purchased  through  the Transfer  Agent  are  entitled  to any
dividends declared beginning on  the next business day  following receipt of  an
order.  As noted above, orders  placed directly with the  Transfer Agent must be
accompanied by  payment. Investors  will be  entitled to  receive capital  gains
distributions  if their order  is received by  the close of  business on the day
prior to the record date for such distributions. Sales personnel are compensated
for selling
 
                                       18
<PAGE>
shares of the Fund at the time of their sale by the Distributor and/or  Selected
Broker-Dealer.  In addition, some sales  personnel of the Selected Broker-Dealer
will receive various types of non-cash compensation as special sales incentives,
including trips, educational and/or business seminars and merchandise. The  Fund
and/or the Distributor reserve the right to reject any purchase order.
 
REDUCED SALES CHARGE
 
    RIGHT  OF ACCUMULATION.  Investors may benefit from a reduction of the sales
charges in accordance with the above schedule if the cumulative net asset  value
of  shares of the Fund  purchased in a single  transaction, together with shares
previously purchased which are held at the time of such transaction, amounts  to
$100,000 or more.
 
    The  Distributor must be notified by the  shareholder at the time a purchase
order is placed  that the purchase  qualifies for the  reduced charge under  the
Right  of  Accumulation. Similar  notification must  be made  in writing  by the
shareholder when such an order is placed by mail. The reduced sales charge  will
not  be granted if:  (a) such notification is  not furnished at  the time of the
order; or (b) a review of the  records of the Distributor or the Transfer  Agent
fails to confirm the investor's represented holdings.
 
    LETTER OF INTENT.  The foregoing schedule of reduced sales charges will also
be  available to investors who  enter into a written  Letter of Intent providing
for the purchase, within a thirteen-month period, of shares of the Fund from the
Distributor. The cost of shares of the Fund which were previously purchased at a
price including a front-end sales charge  during the 90-day period prior to  the
date  of receipt  by the Distributor  of the  Letter of Intent,  which are still
owned by the  shareholder, may also  be included in  determining the  applicable
reduction.
 
    For  further information concerning purchases  of the Fund's shares, contact
the Distributor or consult the Statement of Additional Information.
 
PLAN OF DISTRIBUTION
 
   
    The Fund has  entered into  a Plan of  Distribution pursuant  to Rule  12b-1
under  the Act, whereby the  expenses of certain activities  and services by the
Distributor and others in the distribution  of the Fund's shares, including  the
payment of commissions for sales of the Fund's shares and incentive compensation
to  and expenses of DWR's account executives and others who engage in or support
distribution of shares or who  service shareholder accounts, including  overhead
and  telephone expenses; printing  and distribution of  prospectuses and reports
used in connection with the offering of the Fund's shares to other than  current
shareholders; and preparation, printing and distribution of sales literature and
advertising materials. Reimbursements for these expenses will be made in monthly
payments by the Fund to the Distributor, which will in no event exceed an amount
equal  to a payment at  the annual rate of  0.20 of 1% of  the average daily net
assets of the Fund. Expenses incurred by the Distributor pursuant to the Plan in
any fiscal year will not be reimbursed  by the Fund through payments accrued  in
any  subsequent  fiscal year.  No interest  or other  financial charges  will be
incurred on any distribution expense incurred by the Distributor under the  Plan
or on any unreimbursed expenses due to the Distributor pursuant to the Plan. The
fee payable pursuant to the Plan, equal to 0.20% of the Fund's average daily net
assets, is characterized as a service fee within the meaning of NASD guidelines.
The   Fund  accrued  $51,691  to  the  Distributor,  pursuant  to  the  Plan  of
Distribution, for the year  ended October 31,  1996. This is  an accrual at  the
annual rate of 0.18% of the Fund's average daily net assets.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The  net asset value per share of the  Fund is determined once daily at 4:00
p.m., New York time on each day that the New York Stock Exchange is open (or, on
days when the New York Stock Exchange closes prior to 4:00 p.m. at such  earlier
 
                                       19
<PAGE>
time),  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 exchange is valued at  its last sale price on that  exchange
prior  to the  time assets  are valued;  if there  were no  sales that  day, the
security is valued at the latest bid price, (in cases where a security is traded
on more than one exchange, the security is valued on the exchange designated  as
the  primary market pursuant to procedures adopted by the Trustees), and (2) all
portfolio securities for  which over-the-counter market  quotations are  readily
available  are valued at  the latest bid  price prior to  the time of valuation.
When market quotations are not readily available, including circumstances  under
which  it is  determined by the  Investment Manager and/or  the Sub-Advisor that
sale or bid prices  are not reflective of  a security's market value,  portfolio
securities  are valued  at their  fair value as  determined in  good faith under
procedures established  by  and under  the  general supervision  of  the  Fund's
Trustees  (valuation of securities  for which market  quotations are not readily
available may also be based upon  current market prices of securities which  are
comparable  in coupon,  rating and maturity  or an  appropriate matrix utilizing
similar factors).
    
 
   
    Certain of  the  Fund's  portfolio  securities  for  which  reliable  market
quotations  are generally not readily available are valued by an outside pricing
service approved  by the  Fund's Trustees.  The pricing  service may  utilize  a
computerized  grid  matrix  and/or  research and  evaluations  by  its  staff in
determining what  it believes  is the  fair value  of the  portfolio  securities
valued by such pricing service.
    
 
    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.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    AUTOMATIC  INVESTMENT OF DIVIDENDS AND  DISTRIBUTIONS.  All income dividends
and capital gains distributions  are automatically paid  in full and  fractional
shares  of the Fund,  (or, if specified  by the shareholder,  any other open-end
investment  company  for  which   InterCapital  serves  as  investment   manager
(collectively,  with the Fund, the "Dean Witter Funds")), unless the shareholder
requests that they be paid in cash. 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
in  shares of the  Fund (or in cash  if the shareholder so  requests) at the net
asset value per share (without sales charge) 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 checks during the
first ten days of the following month.
 
   
    EASYINVESTSM.   Shareholders  may  subscribe  to  EasyInvest,  an  automatic
purchase  plan  which  provides  for  any  amount  from  $100  to  $5,000  to be
transferred automatically from a checking or savings account, on a semi-monthly,
monthly or quarterly basis,  to the Transfer Agent  for investment in shares  of
the  Fund (see  "Purchase of  Fund Shares"  and "Redemptions  and Repurchases --
Involuntary Redemption").
    
 
                                       20
<PAGE>
    SYSTEMATIC WITHDRAWAL PLAN.  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, December)  checks in any dollar  amount, not less than
$25 or in any whole percentage of the account balances, 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.
 
    EXCHANGE  PRIVILEGE.    The  Fund makes  available  to  its  shareholders an
"Exchange Privilege" allowing the exchange of  shares of the Fund for shares  of
other Dean Witter Funds sold with a front-end (at time of purchase) sales charge
("FESC  funds"), for shares of Dean Witter Funds sold with a contingent deferred
sales charge  ("CDSC funds"),  and for  shares of  Dean Witter  Short-Term  U.S.
Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean Witter Short-Term
Bond  Fund, Dean Witter  Balanced Growth Fund, Dean  Witter Balanced Income Fund
and Dean Witter Intermediate Term U.S. Treasury Trust and five Dean Witter Funds
which are money market funds (the  foregoing eleven non-FESC and non-CDSC  funds
are  hereinafter referred  to as  the "Exchange  Funds"). Exchanges  may be made
after the shares of the Fund acquired  by purchase (not by exchange or  dividend
reinvestment)  have been held  for thirty days.  There is no  waiting period for
exchanges of  shares acquired  by exchange  or dividend  reinvestment.  However,
shares  of CDSC funds, including shares acquired  in exchange for shares of FESC
funds, may not  be exchanged for  shares of FESC  funds. Thus, shareholders  who
exchange  their Fund shares  for shares of CDSC  funds may subsequently exchange
those shares  for shares  of other  CDSC funds  or Exchange  Funds but  may  not
reacquire FESC fund shares by exchange.
 
    An exchange to another FESC fund, to a CDSC fund or to an Exchange Fund that
is  not a  money-market fund is  on the basis  of the next  calculated net asset
value per  share  of  each fund  after  the  exchange order  is  received.  When
exchanging  into  a money  market fund  from the  Fund, shares  of the  Fund are
redeemed out  of the  Fund at  their next  calculated net  asset value  and  the
proceeds  of the redemption are used to purchase shares of the money market fund
at their  net asset  value  determined the  following business  day.  Subsequent
exchanges  between any of the  Exchange Funds, FESC funds  and CDSC funds can be
effected on the same basis  (except that CDSC fund  shares may not be  exchanged
for shares of FESC funds). 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  contingent
deferred sales charge upon their redemption.
 
    Purchases  and  exchanges should  be made  for  investment purposes  only. A
pattern of frequent  exchanges may  be deemed by  the Investment  Manager to  be
abusive and contrary to the best interests of the Fund's other shareholders and,
at  the Investment Manager's discretion, may be limited by the Fund's refusal to
accept additional purchases and/  or exchanges from  the investor. Although  the
Fund  does not  have any  specific definition of  what constitutes  a pattern of
frequent exchanges,  and  will  consider all  relevant  factors  in  determining
whether  a particular situation is abusive and contrary to the best interests of
the Fund and its other shareholders, investors should be aware that the Fund and
each of the other Dean Witter Funds  may in their discretion limit or  otherwise
restrict  the number of  times this Exchange  Privilege may be  exercised by any
investor. Any such restriction will be made  by the Fund on a prospective  basis
only,  upon notice  to the  shareholder not later  than ten  days following such
shareholder's  most  recent  exchange.  Also,  the  Exchange  Privilege  may  be
terminated  or revised at  any time by the  Fund and/or any  of such Dean Witter
Funds for which shares of the Fund may be exchanged, upon such notice as may  be
required  by  applicable  regulatory agencies.  Shareholders  maintaining margin
accounts with DWR or another
 
                                       21
<PAGE>
Selected  Broker-Dealer  are  referred  to  their  account  executive  regarding
restrictions on exchange of shares of the Fund pledged in their margin account.
 
    The  current prospectus for each  fund describes its investment objective(s)
and policies, and  shareholders should obtain  a copy and  examine it  carefully
before  investing. Exchanges are  subject to the  minimum investment requirement
and any other conditions imposed by each  fund. An exchange will be treated  for
federal income tax purposes the same as a repurchase or redemption of shares, on
which  the shareholder may realize a capital  gain or loss. However, the ability
to deduct capital losses on an exchange may be limited in situations where there
is an exchange of shares within ninety days after the shares are purchased.  The
Exchange  Privilege is only available in states where an exchange may legally be
made.
 
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account  numbers  are part  of  the account  information,  shareholders  may
initiate  an exchange of shares of the Fund for shares of any of the Dean Witter
Funds (for which the Exchange Privilege is available) pursuant to this  Exchange
Privilege   by  contacting  their  account   executive  (no  Exchange  Privilege
Authorization Form is required). Other shareholders (and those shareholders  who
are  clients  of DWR  or another  Selected  Broker-Dealer but  who wish  to make
exchanges directly by writing or  telephoning the Transfer Agent) must  complete
and  forward to  the Transfer  Agent an  Exchange Privilege  Authorization form,
copies of which may be obtained from the Transfer Agent to initiate an exchange.
If the  Authorization Form  is used,  exchanges may  be made  in writing  or  by
contacting  the  Transfer Agent  at (800)  869-NEWS  (toll-free). The  Fund will
employ reasonable procedures to confirm that exchange instructions  communicated
over  the telephone are  genuine. Such procedures  may include requiring various
forms of personal identification such as name, mailing address, social  security
or  other  tax identification  number and  DWR  or other  Selected Broker-Dealer
account number (if any).  Telephone instructions may also  be recorded. If  such
procedures  are  not employed,  the Fund  may be  liable for  any losses  due to
unauthorized or fraudulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m.  and 4:00 p.m. New  York time, on any  day the New  York
Stock  Exchange is  open. Any  shareholder wishing to  make an  exchange who has
previously filed an Exchange Privilege Authorization  Form and who is unable  to
reach  the Fund  by telephone should  contact his  or her DWR  or other Selected
Broker-Dealer account  executive, if  appropriate, or  make a  written  exchange
request.  Shareholders are  advised that during  periods of  drastic economic or
market changes, it  is possible that  the telephone exchange  procedures may  be
difficult to implement, although this has not been the case with the Dean Witter
Funds in the past.
 
    For additional information about the Exchange Privilege, shareholders should
contact  their  DWR or  other Selected  Broker-Dealer  account executive  or the
Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    REDEMPTION.  Shares  of the Fund  can be redeemed  for cash at  any time  at
their  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 sent to the Fund's Transfer Agent
at P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held  by
the   shareholder(s),   the  shares   may  be   redeemed  by   surrendering  the
certificate(s) with a written request for redemption, along with any  additional
information required by the Transfer Agent.
 
    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
 
                                       22
<PAGE>
account without a share certificate may 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 Share  --
Determination  of Net  Asset Value")  after such  repurchase order  is received.
Repurchase orders received  by DWR  and other Selected  Broker-Dealers prior  to
4:00  p.m., New York time, on  any business day will be  priced at the net asset
value per share that  is based on that  day's close. Repurchase orders  received
after 4:00 p.m., New York time, will be priced on the basis of the next business
day's close. Selected Broker-Dealers may charge for their services in connection
with  the repurchase, but the Fund, DWR and the Distributor do not charge a fee.
Payment for shares repurchased may be made by the Fund to DWR and other Selected
Broker-Dealers for the account  of the shareholder. The  offer by DWR and  other
Selected Broker-Dealers to repurchase shares from dealers or shareholders may be
suspended  by them  at any  time. In that  event, shareholders  may redeem their
shares through the Fund's Transfer Agent as set forth above under "Redemption."
 
    PAYMENT FOR SHARES REDEEMED  OR REPURCHASED.   Payment for shares  presented
for  repurchase or  redemption will  be made  by check  within seven  days after
receipt by the Transfer Agent of the certificate and/or written request in  good
order.  Such payment may be postponed or the right of redemption suspended under
unusual circumstances, e.g., at times when normal trading is not taking place on
the New York Stock  Exchange. If the  shares to be  redeemed have recently  been
purchased by check, payment of the redemption pro-
ceeds  may be delayed for the minimum time  needed to verify that the check used
for investment has been  honored (not more  than fifteen days  from the time  of
receipt  of the  check by the  Transfer Agent).  Shareholders maintaining margin
accounts with  DWR  or another  Selected  Broker-Dealer are  referred  to  their
account  executive regarding  restrictions on redemption  of shares  of the Fund
pledged in the margin account.
 
    REINSTATEMENT PRIVILEGE.   A  shareholder  who has  had  his or  her  shares
redeemed  or  repurchased and  has not  previously exercised  this reinstatement
privilege may, within 30  days after the date  of the redemption or  repurchase,
reinstate any portion or all of the proceeds of such redemption or repurchase in
shares  of  the Fund  at their  net asset  value (without  a sales  charge) next
determined after  a  reinstatement  request,  together  with  the  proceeds,  is
received by the Transfer Agent.
 
   
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice,
to  redeem at their net  asset value, the shares  of any shareholder (other than
shares held  in an  Individual  Retirement Account  or custodial  account  under
Section 403(b)(7) of the Internal Revenue Code) whose shares, due to redemptions
by the shareholder, have a value of less than $100 as a result of redemptions or
repurchases,  or such lesser amount as may be fixed by the Board of Trustees or,
in the case of  an account opened through  EasyInvestSM, if after twelve  months
the  shareholder has invested  less than $1,000 in  the account. However, before
the Fund redeems such shares and sends the proceeds to the shareholder, it  will
notify  the shareholder that the value of the shares is less than the applicable
amount and allow the shareholder sixty days to make an additional investment  in
an  amount  which  will  increase the  value  of  the account  to  at  least the
applicable amount before the redemption is processed.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS  AND  DISTRIBUTIONS.    The  Fund  declares  dividends  from   net
investment  income on each day the New  York Stock Exchange is open for business
to shareholders of  record as of  the close of  business the preceding  business
day.    Such    dividends   are    paid   monthly.    The   Fund    intends   to
dis-
 
                                       23
<PAGE>
tribute all of the Fund's net investment income on an annual basis.
 
    Net realized  short-term  and  long-term  capital gains,  if  any,  will  be
distributed at least once per year, although the Investment Manager reserves the
right to retain a portion of long-term gains for reinvestment.
 
    All  dividends and  capital gains distributions  will be  paid in additional
Fund  shares  (without   sales  charge)  and   automatically  credited  to   the
shareholder's  account  without  issuance  of  a  share  certificate  unless the
shareholder requests  in  writing that  all  dividends  be paid  in  cash.  (See
"Shareholder Services -- Automatic Investment of Dividends and Distributions".)
 
    TAXES.   Because the  Fund intends to  distribute all of  its net investment
income and net  short-term capital  gains to shareholders  and otherwise  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.
 
    Gains  or losses on the Fund's transactions in listed options on securities,
futures and options on futures may be treated as 60% long-term 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 short-term  gains being available for
distribution.
 
    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 received by the shareholder in
the prior year.
 
    After the  end  of  the  calendar  year,  shareholders  will  be  sent  full
information  on  their dividends  and any  capital  gains distributions  for tax
purposes, including information as  to the portion  taxable as ordinary  income,
the  portion taxable as capital  gains and any portion  treated as a non-taxable
return of capital. Any such return of capital will reduce the shareholders'  tax
basis  in  their  shares.  To  avoid  being  subject  to  a  31%  federal backup
withholding  tax  on  taxable  dividends,  distributions  and  the  proceeds  of
redemptions  and repurchases, shareholders' taxpayer identification numbers must
be furnished and certified as to their accuracy.
 
    Distributions of  net  long-term  capital  gains, if  any,  are  taxable  to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional  shares or in cash. Capital  gains distributions are not eligible for
the corporate dividends received deduction.
 
   
    The Fund may at times  make payments from sources  other than income or  net
capital gains. Payments from such sources will, in effect, represent a return of
a  portion of each shareholder's investment. All,  or a portion of such payments
will not be taxable to shareholders.
    
 
    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 advisor. Shareholders  will be notified annually  by the Fund as to
the Federal tax status  of dividends and distributions  paid or retained by  the
Fund.
 
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
 
                                       24
<PAGE>
and  are not intended to  indicate future performance. The  yield of the Fund is
computed by dividing the Fund's net investment income over a 30-day period by an
average value (using the average number of shares entitled to receive  dividends
and  the maximum  offering price  per share at  the end  of the  period), all in
accordance with applicable  regulatory requirements. Such  amount is  compounded
for  six months  and then  annualized for  a twelve-month  period to  derive the
Fund's yield.
 
    The "average annual total return" of the Fund refers to a figure  reflecting
the  average annualized  percentage increase  (or decrease)  in the  value of an
initial investment in  the Fund  of $1,000  over periods  of one,  five and  ten
years,  or 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 all
sales charges  incurred  by  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, year-by-year or  other
types  of total  return figures.  Such calculations may  or may  not reflect the
deduction of the front-end  sales charge which, if  reflected, would reduce  the
performance  quoted.  The Fund  may also  advertise  the growth  of hypothetical
investments of $10,000, $50,000 and $100,000 in  shares of the Fund by adding  1
to  the Fund's aggregate total return to date and multiplying by $9,700, $48,500
and $97,500 ($10,000, $50,000  and $100,000 adjusted for  3%, 3% and 2.5%  sales
charges,  respectively.  The  Fund from  time  to  time may  also  advertise its
performance relative to  certain performance  rankings and  indexes compiled  by
independent organizations such as Lipper Analytical Services, Inc.
 
ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
    VOTING  RIGHTS.  All shares of beneficial  interest of the Fund are of $0.01
par value and are equal as to earnings, assets and voting privileges.
 
    The Fund is  not required to  hold Annual Meetings  of Shareholders, and  in
ordinary  circumstances  the Fund  does not  intend to  hold such  meetings. The
Trustees may call  Special Meetings  of Shareholders for  action by  shareholder
vote  as may be required  by the Act or the  Declaration of Trust. Under certain
circumstances, the Trustees may be removed by  action of the Trustees or by  the
Shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
circumstances,  be held  personally liable  as partners  for obligations  of the
Fund. However,  the  Declaration of  Trust  contains an  express  disclaimer  of
shareholder  liability for  acts or  obligations of  the Fund  and requires that
notice of such disclaimer be given  in each instrument entered into or  executed
by  the Fund, and provides for indemnification and reimbursement of expenses out
of the  Fund's property  for  any shareholder  held  personally liable  for  the
obligations  of the  Fund. Thus, the  risk of a  shareholder incurring financial
loss on account of  shareholder liability is limited  to circumstances in  which
the  Fund  itself would  be  unable to  meet  its obligations.  Given  the above
limitations on  shareholder personal  liability, and  the nature  of the  Fund's
assets  and operations,  the possibility  of the Fund  being unable  to meet its
obligations is remote and, in the opinion of Massachusetts counsel to the  Fund,
the risk to Fund shareholders of personal liability is remote.
 
   
    CODE  OF ETHICS.   Directors, officers  and employees  of InterCapital, Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest, that no undue personal benefit is obtained from a person's  employment
activities  and that actual and potential  conflicts of interest are avoided. To
achieve   these   goals   and   comply   with   regulatory   requirements,   the
    
 
                                       25
<PAGE>
   
Code   of  Ethics  requires,  among   other  things,  that  personal  securities
transactions by employees of  the companies be subject  to an advance  clearance
process  to monitor that  no Dean Witter Fund  is engaged at the  same time in a
purchase or sale of the same security.  The Code of Ethics bans the purchase  of
securities in an initial public offering, and also prohibits engaging in futures
and  options  transactions  and  profiting on  short-term  trading  (that  is, a
purchase within sixty days of a sale or a sale within sixty days of a  purchase)
of  a security.  In addition,  investment personnel may  not purchase  or sell a
security for  their personal  account within  thirty days  before or  after  any
transaction  in any Dean Witter Fund managed by them. Any violations of the Code
of Ethics are subject to sanctions, including reprimand, demotion or  suspension
or  termination  of  employment. The  Code  of Ethics  comports  with regulatory
requirements and  the  recommendations in  the  1994 report  by  the  Investment
Company Institute Advisory Group on Personal Investing.
    
 
   
    The  Fund's  Sub-Adviser  also has  a  Code  of Ethics  which  complies with
regulatory requirements and, insofar  as it relates  to persons associated  with
the  Fund, 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
March 27, 1991.
 
THE INVESTMENT MANAGER
 
    Dean  Witter  InterCapital Inc.,  a  Delaware corporation,  (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  investment  advisory,  administrative  and  management  activities
previously performed by the InterCapital  Division of Dean Witter Reynolds  Inc.
("DWR"), a broker-dealer affiliate of InterCapital. (As hereinafter used in this
Statement  of Additional  Information, the terms  "InterCapital" and "Investment
Manager"  refer  to   DWR's  InterCapital   Division  prior   to  the   internal
reorganization   and  Dean  Witter  InterCapital  Inc.  thereafter.)  The  daily
management of the Fund is conducted by or under the direction of officers of the
Fund and of  the Investment Manager  and Sub-Advisor, subject  to review by  the
Fund's  Board of Trustees. In addition, Trustees of the Fund provide guidance on
economic factors and interest rate trends. Information as to these Trustees  and
officers is contained under the caption "Trustees and Officers".
 
    InterCapital  is also  the investment manager  or investment  adviser of the
following management  investment companies:  Active Assets  Money Trust,  Active

Opportunities  Trust  II, Municipal  Income  Opportunities Trust  III, Municipal
Premium Income Trust and Prime Income Trust. The foregoing investment companies,
together with the Fund, are collectively referred to as the Dean Witter Funds.
 
    In addition,  Dean Witter  Services Company  Inc. ("DWSC"),  a  wholly-owned
subsidiary  of  InterCapital, serves  as  manager for  the  following investment
companies for which TCW Funds Management, Inc. is the investment adviser: TCW/DW
Core Equity Trust, TCW/DW North  American Government Income Trust, TCW/DW  Latin
American  Growth Fund,  TCW/DW Income and  Growth Fund, TCW/DW  Small Cap Growth
Fund, TCW/DW Balanced  Fund, TCW/DW  Mid-Cap Equity Trust,  TCW/DW Total  Return
Trust,  TCW/DW  Global  Telecom  Trust, TCW/DW  Strategic  Income  Trust, TCW/DW
Emerging Markets Opportunities Trust, TCW/DW Term Trust 2000, TCW/DW Term  Trust
2002  and TCW/DW Term Trust 2003  (the "TCW/DW Funds"). InterCapital also serves
as: (i)  sub-adviser  to  Templeton  Global  Opportunities  Trust,  an  open-end
investment  company; (ii)  administrator of  The BlackRock  Strategic Term Trust
Inc., a closed-end investment company; and (iii) sub-administrator of MassMutual
Participation  Investors  and   Templeton  Global   Governments  Income   Trust,
closed-end investment companies.
 
    Pursuant  to an Investment Management Agreement (the "Management Agreement")
with the Investment  Manager, the Fund  has retained the  Investment Manager  to
supervise  the investment of the Fund's  assets. The Investment Manager, through
consultation with BlackRock  Financial Management Inc.  (the "Sub-Advisor")  and
through   its  own  portfolio  management  staff,  obtains  and  evaluates  such
information and advice relating to the economy, securities markets, and specific
securities as  it considers  necessary  or useful  to continuously  oversee  the
management  of the assets of the Fund in a manner consistent with its investment
objective.
 
    Under the terms  of the  Management Agreement, the  Investment Manager  also
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, DWSC began to provide the administrative services to  the
Fund that 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 of 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 Management Agreement.
 
    Expenses   not  expressly  assumed  by  the  Investment  Manager  under  the
Management Agreement, by the Sub-Advisor pursuant to the Sub-Advisory  Agreement
(see  below), or by the Distributor of the Fund's shares (see "The Distributor")
will be paid by the  Fund. The expenses borne by  the Fund include, but are  not
limited  to: expenses of  the Plan of  Distribution pursuant to  Rule 12b-1 (see
"The Distributor"),  charges and  expenses of  any registrar,  custodian,  stock
transfer  and dividend disbursing agent; brokerage commissions; taxes; engraving
and printing  of share  certificates; registration  costs of  the Fund  and  its
shares  under  federal  and  state  securities laws;  the  cost  and  expense of
printing, including typesetting, and distributing Prospectuses and Statements of
Additional Information  of  the  Fund  and supplements  thereto  to  the  Fund's
shareholders;  all  expenses  of  shareholders' and  Trustees'  meetings  and of
preparing, printing and mailing of proxy statements and reports to shareholders;
fees and  travel  expenses of  Trustees  or members  of  any advisory  board  or
committee who are not employees of the
 
                                       4
<PAGE>
Investment  Manager or Sub-Advisor or any  corporate affiliate of the Investment
Manager or Sub-Advisor;  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 the Fund's legal counsel, including
counsel to the Trustees  who are not  interested persons of the  Fund or of  the
Investment  Manager or  Sub-Advisor (not  including compensation  or expenses of
attorneys who  are  employees of  the  Investment Manager  or  Sub-Advisor)  and
independent  accountants; membership dues of  industry associations; interest on
Fund borrowings; postage; insurance premiums on property or personnel (including
officers and directors) of  the Fund which inure  to its benefit;  extraordinary
expenses  (including,  but  not limited  to,  legal claims  and  liabilities and
litigation costs and any indemnification relating thereto); and all other  costs
of the Fund's operation.
 
    The   Management  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  Management Agreement in no
way restricts  the  Investment Manager  from  acting as  investment  manager  or
adviser to others.
 
    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 0.50% to the Fund's daily net assets. For the fiscal years ended October
31, 1996,  1995 and  1994, the  Fund  accrued to  the Investment  Manager  total
compensation under the Management Agreement in the amounts of $140,979, $178,248
and $306,372, respectively.
 
    Pursuant  to a Sub-Advisory Agreement between the Investment Manager and the
Sub-Advisor,  the  Sub-Advisor  has  been  retained,  subject  to  the   overall
supervision  of  the  Investment  Manager  and  the  Trustees  of  the  Fund, to
continuously furnish investment advice concerning individual portfolio  security
selections.
 
    The  Sub-Advisor  provides asset  management services  with respect  to high
quality fixed income  instruments, with particular  emphasis on  Mortgage-Backed
Securities.  The Sub-Advisor currently serves as the investment adviser to fixed
income investors in  the United States  and overseas through  several funds  and
separate  accounts  with  combined  assets under  management  in  excess  of $43
billion. These  include twenty-one  closed-end  investment companies  traded  on
either  the New  York or  American Stock  Exchanges: The  BlackRock Income Trust
Inc., The BlackRock Target Term Trust  Inc., The BlackRock Advantage Term  Trust
Inc.,  The BlackRock  Strategic Term Trust  Inc., The BlackRock  1998 Term Trust
Inc., The BlackRock Municipal Term  Trust Inc., The BlackRock Insured  Municipal
Term  Trust Inc., The BlackRock North American Government Income Trust Inc., The
BlackRock Investment Quality  Term Trust Inc.,  The BlackRock Insured  Municipal

Inc.,  The  BlackRock  Florida  Insured  Municipal  2008  Term  Trust  Inc., The
BlackRock New York Insured  Municipal 2008 Term Trust  Inc., The BlackRock  1999

Investment Quality Municipal  Trust Inc.,  The BlackRock  New Jersey  Investment
Quality  Municipal Trust  Inc., The BlackRock  Investment Grade  2009 Term Trust
Inc. and The BlackRock 2001 Term Trust Inc., which were designed for  individual
investors.  Each of  these funds is  a closed-end  management investment company
that invests  primarily in  investment  grade Mortgage-Backed  and  Asset-Backed
Securities  and  in  securities  that  are  issued  or  guaranteed  by  the U.S.
government or one of its agencies  or instrumentalities or invests in  Municipal
Securities.  The  Sub-Advisor also  serves as  the  investment advisor  to three
offshore funds: BlackRock  Fund for  Fannie Mae  Mortgage Securities,  BlackRock
Freddie  Mac Mortgage  Securities Fund,  and BSY  Financial Corp.  Each of these
funds invests primarily  in U.S.  Mortgage-Backed Securities.  In addition,  the
Sub-Advisor  serves as investment advisor  to several institutional investors in
separate accounts.

    The Sub-Advisor's general and limited partners and employees include several
individuals with extensive experience in  creating, evaluating and investing  in
Mortgage-Backed  Securities, Asset-Backed Securities and hedging products. Prior
to co-founding the  Sub-Advisor (of which  he is a  general partner), from  July
1976  to  March  1988,  Laurence  D.  Fink  was  employed  by  The  First Boston
Corporation where he had been a  Managing Director since January 1979. At  First
Boston,  he was a member of the  Management Committee and co-head of its Taxable
Fixed Income Division. He  also managed the Financial  Futures and Fixed  Income
Options  Department and  the Mortgage and  Real Estate Products  Group. Ralph L.
Schlosstein, President and  a co-founder of  the Sub-Advisor (of  which he is  a
general  partner), was employed  by Shearson Lehman  Brothers Inc. from February
1981 to March 1988 and became a  Managing Director in August, 1984. At  Shearson
Lehman,  he was co-head of the  Mortgage and Savings Institutions Group. Messrs.
Fink and  Schlosstein,  along  with  other  members  of  the  Sub-Advisor,  were
instrumental  in  many of  the major  innovations  in these  securities markets,
including the creation of  the fixed and  floating rate collateralized  mortgage
obligation,   asset-backed  securities  and   the  senior-subordinated  mortgage
pass-through securities.
 
    On June 16, 1994, the partners of the Sub-Adviser entered into a  definitive
agreement  to sell their  partnership interests in the  Sub-Advisor to PNC Bank,
N.A. ("PNC"), headquartered in Pittsburgh, Pennsylvania (the "Transaction"). The
Transaction, which was subject to  bank regulatory approval, closed on  February
28,  1995  and  was  subject to  various  conditions,  including  the following:
BlackRock will retain its name and will continue to operate out of its New  York
office.  All members of the Sub-Advisor's  senior management team agreed to sign
long-term employment contracts  and be responsible  for managing the  day-to-day
affairs  of the Sub-Advisor. Following the  closing of the Transaction, the Sub-
Advisor became  a  wholly-owned corporate  subsidiary  of PNC  Asset  Management
Group, Inc., the holding company for PNC's asset management business.
 
    PNC is a commercial bank offering a wide range of domestic and international
commercial  banking, retail  banking and  trust services  to its  customers. Its
principal office is located in  Pittsburgh, Pennsylvania. PNC is a  wholly-owned
indirect  subsidiary of PNC  Bank Corp. (the "Holding  Company"), a bank holding
company organized under the laws of the Commonwealth of Pennsylvania.
 
    In order to assure continuity of  investment advisory services to the  Trust
by the Sub-Adviser after the Transaction, the Board met in person on October 20,
1994,  for the purpose of considering whether  it would be in the best interests
of the Trust and its shareholders for InterCapital to enter into a  sub-advisory
agreement  with the Sub-Advisor  (the "current Sub-Advisory  Agreement") to take
effect upon  consummation  of  the  Transaction.  At  its  meeting,  the  Board,
including each of the Trustees who are not "interested persons" of the Trust, as
that  term is defined in the  1940 Act (the "Independent Trustees"), unanimously
approved the current Sub-Advisory Agreement  and recommended it for approval  by
Shareholders.  The  current Sub-Advisory  Agreement is  identical to  the former
Sub-Advisory Agreement except for the  effective date and the stated  expiration
date.  At the meeting of shareholders which took place on February 17, 1995, the
shareholders of the Fund voted  to approve the Sub-Advisory Agreement  effective
February 27, 1995.
 
    Both the Investment Manager and the Sub-Advisor have authorized any of their
directors, partners, officers and employees who have been elected as Trustees or
officers of the Fund to serve in the capacities in which they have been elected.
Services  furnished by directors, the Investment Manager and the Sub-Advisor may
be furnished by directors,  partners, officers and  employees of the  Investment
Manager  and the  Sub-Advisor. In connection  with the services  rendered by the
Sub-Advisor, the Sub-Advisor bears the following expenses: (a) the salaries  and
expenses  of its personnel;  and (b) all  expenses incurred by  it in connection
with performing the services provided by it as Sub-Advisor, as described above.
 
    As full compensation for the services  and facilities furnished to the  Fund
and  the Investment Manager and expenses of  the Fund and the Investment Manager
assumed by the Sub-Advisor, the Investment Manager pays the Sub-Advisor  monthly
compensation  equal  to 40%  of  the Investment  Manager's  monthly compensation
payable   under    the   Management    Agreement.   For    the   fiscal    years
 
                                       6
<PAGE>
ended  October 31, 1996, 1995 and 1994, the Investment Manager informed the Fund
that the Investment Manager accrued to the Sub-Advisor total compensation  under
the Sub-Advisory Agreement of $56,391, $71,299 and $122,549, respectively.
 
    The Investment Manager paid the organizational expenses of the Fund incurred
prior  to the offering of the Fund's  shares. The Fund reimbursed the Investment
Manager for  $150,000 of  such expenses,  in accordance  with the  terms of  the
Underwriting  Agreement between the Fund  and DWR. 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 Management Agreement and  the Sub-Advisory Agreement (the  "Agreements")
were  initially approved by the Board of Trustees on October 30, 1992 and by the
shareholders of the Fund at a Meeting of Shareholders held on January 12,  1993.
The  Agreements are substantially  identical to the  prior investment management
agreement and sub-advisory agreement which were initially approved by the Fund's
Trustees on April 16, 1991  and by DWR as the  then sole shareholder on May  15,
1991.  The Agreements took effect on June  30, 1993, upon the spin-off of Sears,
Roebuck and  Co.  of  its remaining  shares  of  DWDC. Both  Agreements  may  be
terminated  at any time, without penalty, on  thirty days notice by the Trustees
of the Fund, by the holders of a majority, as defined in the Investment  Company
Act  of 1940, as amended (the "Act"), of  the outstanding shares of the Fund, by
the Investment Manager,  or the Sub-Advisor  (Sub-Advisory Agreement only).  The
Agreements  will automatically  terminate in the  event of  their assignment (as
defined in the Act).
 
    Under its  terms, the  current Sub-Advisory  Agreement had  an initial  term
ending  April 30, 1995 and  the Management Agreement had  an initial term ending
April 30,  1994, and  each provides  that it  will continue  from year  to  year
thereafter, provided continuance of each Agreement is approved at least annually
by  the  vote of  the holders  of  a majority,  as defined  in  the Act,  of the
outstanding shares of the Fund, or by the Trustees of the Fund; provided that in
either event such continuance is approved annually by the vote of a majority  of
the  Trustees of the Fund  who are not parties  to the Agreements or "interested
persons" (as defined in the Act) of any such party (the "Independent Trustees"),
which votes must be cast in person at a meeting called for the purpose of voting
on such approval. At their meeting held  on April 17, 1996, the Fund's Board  of
Trustees,   including  a   majority  of   the  Independent   Trustees,  approved
continuation of each Agreement until April 30, 1997.
 
    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR. The Fund has agreed that DWR or its parent company may use, or at any  time
permit  others to use, the name "Dean Witter".  The Fund has also agreed that in
the event the Management Agreement is terminated, or if the affiliation  between
InterCapital  and its parent company is  terminated, the Fund will eliminate the
name "Dean Witter" from its name if DWR or its parent company shall so request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
 
    The Board of Trustees consists of eight (8) trustees. These same individuals
also serve as directors or  trustees for all of the  Dean Witter Funds, and  are
referred  to in this  section as Trustees. As  of the date  of this Statement of
Additional Information, there are a total of 82 Dean Witter Funds, comprised  of
122  portfolios. As of  November 30, 1996,  the Dean Witter  Funds had total net
assets of approximately $82.2 billion and more than five million shareholders.
 
    Six Trustees  (75% of  the total  number) have  no affiliation  or  business
connection with InterCapital or any of its affiliated persons and do not own any
stock  or other securities issued by  InterCapital's parent company, DWDC. These
are the "disinterested" or "independent"  Trustees. The other two Trustees  (the
"management  Trustees")  are affiliated  with  InterCapital. Five  of  the seven
independent Trustees are also Independent Trustees of the TCW/DW Funds.
 
    Law and regulation establish both general guidelines and specific duties for
the Independent Trustees.  The Dean  Witter Funds seek  as Independent  Trustees
individuals  of distinction and  experience in business  and finance, government
service or academia; these are people whose advice and counsel are in demand  by
others  and for  whom there is  often competition.  To accept a  position on the
Funds' Boards, such individuals may reject other attractive assignments  because
the  Funds make  substantial demands  on their time.  Indeed, by  serving on the
Funds' Boards, certain Trustees who would  otherwise be qualified and in  demand
to serve on bank boards would be prohibited by law from doing so.
 
    All  of the Independent Trustees serve as members of the Audit Committee and
the Committee of the Independent Trustees.  Three of them also serve as  members
of  the Derivatives Committee. During the calendar year ended December 31, 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 AUDIT COMMITTEE
 
    The Chairman  of the  Committee of  the Independent  Trstees and  the  Audit
Committee  maintains an  office at  the Funds' headquarters  in New  York. He is
responsible for keeping abreast of regulatory and
 
                                       10
<PAGE>
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 all  three 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 Committees of  the independent Trustees  and the  Audit
Committee  is  not  employed by  any  other  organization and  devotes  his time
primarily to  the services  he performs  as Committee  Chairman and  Independent
Trustee  of the Dean Witter Funds and  as an Independent Trustee and, since July
1, 1996, as Chairman of the Committee of the independent Trustees and the  Audit
Committee  of the TCW/DW Funds. The current Committee Chairman has had more than
35 years experience as a senior executive in the investment company industry.
 
ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL DEAN
WITTER FUNDS
 
    The Independent Trustees and the  Funds' management believe that having  the
same  Independent  Trustees  for  each  of  the  Dean  Witter  Funds  avoids the
duplication  of  effort  that  would  arise  from  having  different  groups  of
individuals  serving as Independent  Trustees for each  of the Funds  or even of
sub-groups of Funds.  They believe  that having  the same  individuals serve  as
Independent  Trustees of  all the  Funds tends  to increase  their knowledge and
expertise regarding matters which affect the Fund complex generally and enhances
their ability  to negotiate  on behalf  of  each Fund  with the  Fund's  service
providers. This arrangement also precludes the possibility of separate groups of
Independent  Trustees arriving at conflicting decisions regarding operations and
management of the  Funds and  avoids the cost  and confusion  that would  likely
ensue.  Finally, having the  same Independent Trustees serve  on all Fund Boards
enhances the ability of  each Fund to  obtain, at modest  cost to each  separate
Fund,  the services of Independent Trustees, and a Chairman of their Committees,
of the caliber, experience and business  acumen of the individuals who serve  as
Independent Trustees of the Dean Witter Funds.
 
COMPENSATION OF INDEPENDENT TRUSTEES
 
    The  Fund pays each Independent  Trustee an annual fee  of $1,000 plus a per
meeting fee of $50 for  meetings of the Board of  Trustees or committees of  the
Board  of Trustees attended  by the Trustee  (the Fund pays  the Chairman of the
Audit Committee an annual fee of $750 and pays the Chairman of the Committee  of
the  Independent Trustees  an additional  annual fee  of $1,200).  The Fund also
reimburses such Trustees for travel and other out-of-pocket expenses incurred by
them in connection with  attending such meetings. Trustees  and officers of  the
Fund  who are or have  been employed by the  Investment Manager or an affiliated
company receive no compensation or expense reimbursement from the Fund.
 
    The  following  table  illustrates  the  compensation  paid  to  the  Fund's
Independent Trustees by the Fund for the fiscal year ended October 31, 1996.

(1) For the 79  Dean Witter Funds  in operation at December  31, 1995. As  noted
    above,  on July 1, 1996,  Mr. Haire became Chairman  of the Committee of the
    Independent Trustees and the Audit Committee of the TCW/DW Funds in addition
    to continuing to serve in such positions for the Dean Witter Funds.
 
    As of the date of this Statement  of Additional Information, 57 of the  Dean
Witter  Funds, including the Fund, have adopted a retirement program under which
an Independent Trustee  who retires after  serving for at  least five years  (or
such lesser period as may be determined by the Board) as an Independent Director
or Trustee of any Dean Witter Fund that has adopted the retirement program (each
such Fund referred to as an "Adopting Fund" and each such Trustee referred to as
an  "Eligible Trustee")  is entitled  to retirement  payments upon  reaching the
eligible retirement age (normally, after attaining age 72). Annual payments  are
based  upon length of service. Currently, upon retirement, each Eligible Trustee
is entitled to  receive from  the Adopting  Fund, commencing  as of  his or  her
retirement  date and continuing for the remainder  of his or her life, an annual
retirement benefit (the "Regular Benefit") equal to 25.0% of his or her Eligible
Compensation plus 0.4166666% of such  Eligible Compensation for each full  month
of  service as an Independent Director or Trustee of any Adopting Fund in excess
of five years up to a maximum of 50.0% after ten years of service. The foregoing
percentages may be changed by the Board.(2) "Eligible Compensation" is one-fifth
of the total  compensation earned by  such Eligible Trustee  for service to  the
Adopting  Fund  in  the five  year  period prior  to  the date  of  the Eligible
Trustee's retirement. Benefits under the  retirement program are not secured  or
funded by the Adopting Funds.
 
    The  following  table illustrates  the  retirement benefits  accrued  to the
Fund's Independent Trustees by  the Fund for the  fiscal year ended October  31,
1996 and by the 57 Dean Witter Funds (including the
 
                                       12

Fund)  as of December  31, 1995, and  the estimated retirement  benefits for the
Fund's Independent Trustees from the Fund as of October 31, 1996 and from the 57
Dean Witter Funds as of December 31, 1995.

(2) An Eligible Trustee  may elect alternate payments  of his or her  retirement
    benefits  based upon the  combined life expectancy  of such Eligible Trustee
    and his or her spouse on the date of such Eligible Trustee's retirement. The
    amount estimated to be payable under  this method, through the remainder  of
    the  later of  the lives of  such Eligible  Trustee and spouse,  will be the
    actuarial equivalent  of  the Regular  Benefit.  In addition,  the  Eligible
    Trustee  may elect that the surviving  spouse's periodic payment of benefits
    will be equal  to either 50%  or 100%  of the previous  periodic amount,  an
    election  that, respectively,  increases or decreases  the previous periodic
    amount so that the  resulting payments will be  the actuarial equivalent  of
    the Regular Benefit.
 
(3)  Based on  current levels  of compensation.  Amount of  annual benefits also
    varies depending on the Trustee's elections described in Footnote (2) above.
 
    As of the date  of this Statement of  Additional Information, the  aggregate
number of shares of beneficial interest of the Fund owned by the Fund's officers
and  Trustees  as a  group  was less  than  1 percent  of  the Fund's  shares of
beneficial interest outstanding.
 
INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
U.S. GOVERNMENT SECURITIES
 
    As discussed  in  the  Prospectus,  the Fund  may  invest  in,  among  other
securities,   securities  issued  by  the   U.S.  Government,  its  agencies  or
instrumentalities. Such securities include:
 
        (1) U.S. Treasury bills (maturities of one year or less), U.S.  Treasury
    notes  (maturities of one  to ten years) and  U.S. Treasury bonds (generally
    maturities of greater than ten years),  all of which are direct  obligations
    of  the U.S.  Government and,  as such,  are backed  by the  "full faith and
    credit" of the United States.
 
        (2) Securities  issued by  agencies and  instrumentalities of  the  U.S.
    Government  which are  backed by  the full  faith and  credit of  the United
    States. Among the  agencies and instrumentalities  issuing such  obligations
    are  the Federal  Housing Administration,  the Government  National Mortgage
    Association ("GNMA"), the Department of  Housing and Urban Development,  the
    Export-Import  Bank, the  Farmers Home Administration,  the General Services
    Administration,  the  Maritime   Administration  and   the  Small   Business
    Administration.  The maturities of such  obligations range from three months
    to 30 years.
 
        (3) Securities issued  by agencies and  instrumentalities which are  not
    backed  by the full faith and credit of the United States, but whose issuing
    agency or instrumentality has the right to borrow, to meet its  obligations,
    from  an existing line of credit with  the U.S. Treasury. Among the agencies
 
                                       13
<PAGE>
    and instrumentalities  issuing such  obligations  are the  Tennessee  Valley
    Authority,  the Federal National Mortgage  Association ("FNMA"), the Federal
    Home Loan Mortgage Corporation ("FHLMC") and the U.S. Postal Service.
 
        (4) Securities issued  by agencies and  instrumentalities which are  not
    backed  by the  full faith and  credit of  the United States,  but which are
    backed by the  credit of the  issuing agency or  instrumentality. Among  the
    agencies and instrumentalities issuing such obligations are the Federal Farm
    Credit System and the Federal Home Loan Banks.
 
    Neither  the value nor the yield of the U.S. Government securities which may
be invested in by the  Fund are guaranteed by  the U.S. Government. Such  values
and  yield will  fluctuate with changes  in prevailing interest  rates and other
factors. Generally, as  prevailing interest rates  rise, the value  of any  U.S.
Government  securities held by  the Fund will fall.  Such securities with longer
maturities generally tend to  produce higher yields and  are subject to  greater
market fluctuation as a result of changes in interest rates than debt securities
with  shorter maturities. The  Fund is not  limited as to  the maturities of the
U.S. Government securities in  which it may  invest with respect  to 35% of  its
total assets.
 
MORTGAGE-BACKED SECURITIES
 
    As  discussed in the Prospectus, the Mortgage-Backed Securities purchased by
the Fund evidence an interest in  a specific pool of mortgages. Such  securities
are issued by GNMA, FNMA and FHLMC.
 
    GNMA  CERTIFICATES.  GNMA is a wholly-owned corporate instrumentality of the
United States  within  the Department  of  Housing and  Urban  Development.  The
National Housing Act of 1934, as amended (the "Housing Act"), authorized GNMA to
guarantee  the timely payment  of the principal of  and interest on certificates
that are based on and backed by a pool of mortgage loans insured by the  Federal
Housing  Administration under the Housing Act, or  Title V of the Housing Act of
1949 ("FHA  Loans"), or  guaranteed by  the Veterans'  Administration under  the
Servicemen's  Readjustment Act of 1944, as amended  ("VA Loans"), or by pools of
other eligible mortgage loans. The Housing Act provides that the full faith  and
credit  of the U.S. Government is pledged to the payment of all amounts that may
be required to be  paid under any  guarantee. In order  to meet its  obligations
under  such guarantee, GNMA is authorized to  borrow from the U.S. Treasury with
no limitations as to amount.
 
    The GNMA Certificates  will represent  a pro rata  interest in  one or  more
pools  of the following  types of mortgage  loans; (i) fixed  rate level payment
mortgage loans; (ii) fixed  rate graduated payment  mortgage loans; (iii)  fixed
rate  growing equity mortgage  loans; (iv) fixed rate  mortgage loans secured by
manufactured (mobile)  homes;  (v)  mortgage loans  on  multifamily  residential
properties  under  construction; (vi)  mortgage  loans on  completed multifamily
projects; (vii) fixed rate mortgage loans as to which escrowed funds are used to
reduce the borrower's monthly  payments during the early  years of the  mortgage
loans  ("buydown"  mortgage  loans);  (viii)  mortgage  loans  that  provide for
adjustments in payments based on periodic changes in interest rates or in  other
payment  terms of the mortgage loans; and (ix) mortgage-backed serial notes. All
of these mortgage loans will be FHA  Loans or VA Loans and, except as  otherwise
specified above, will be fully-amortizing loans secured by first liens on one-to
four-family housing units.
 
    FNMA  CERTIFICATES.    FNMA is  a  federally chartered  and  privately owned
corporation  organized  and  existing   under  the  Federal  National   Mortgage
Association  Charter  Act. FNMA  was originally  established in  1938 as  a U.S.
Government agency to provide supplemental  liquidity to the mortgage market  and
was  transformed into a  stockholder owned and  privately managed corporation by
legislation enacted  in  1968.  FNMA  provides  funds  to  the  mortgage  market
primarily  by  purchasing  home  mortgage  loans  from  local  lenders,  thereby
replenishing their funds for additional lending. FNMA acquires funds to purchase
home mortgage loans from many capital  market investors that may not  ordinarily
invest  in mortgage loans directly, thereby  expanding the total amount of funds
available for housing.
 
    Each FNMA Certificate will entitle the registered holder thereof to  receive
amounts  representing  such holder's  pro rata  interest in  scheduled principal
payments and interest  payments (at such  FNMA Certificate's pass-through  rate,
which   is  net  of   any  servicing  and  guarantee   fees  on  the  underlying
 
                                       14
<PAGE>
mortgage loans), and any principal prepayments on the mortgage loans in the pool
represented by such FNMA Certificate and such holder's proportionate interest in
the full  principal amount  of any  foreclosed or  otherwise finally  liquidated
mortgage  loan. The full and timely payment of principal of and interest on each
FNMA Certificate will be  guaranteed by FNMA, which  guarantee is not backed  by
the full faith and credit of the U.S. Government.
 
    Each  FNMA Certificate  will represent  a pro rata  interest in  one or more
pools of FHA  Loans, VA  Loans or  conventional mortgage  loans (i.e.,  mortgage
loans  that are  not insured  or guaranteed by  any governmental  agency) of the
following types: (i) fixed  rate level payment mortgage  loans; (ii) fixed  rate
growing  equity  mortgage loans;  (iii)  fixed rate  graduated  payment mortgage
loans; (iv) variable rate California  mortgage loans; (v) other adjustable  rate
mortgage  loans;  and  (vi) fixed  rate  mortgage loans  secured  by multifamily
projects.
 
    FHLMC CERTIFICATES.   FHLMC  is a  corporate instrumentality  of the  United
States  created pursuant to the  Emergency Home Finance Act  of 1970, as amended
(the "FHLMC Act"). FHLMC was established primarily for the purpose of increasing
the availability of  mortgage credit for  the financing of  needed housing.  The
principal  activity of FHLMC  currently consists of the  purchase of first lien,
conventional, residential  mortgage loans  and participation  interests in  such
mortgage  loans and the resale of the mortgage loans so purchased in the form of
mortgage securities, primarily FHLMC Certificates.
 
    FHLMC guarantees to each registered holder of a FHLMC Certificate the timely
payment of interest at the rate provided for by such FHLMC Certificate,  whether
or  not received.  FHLMC also  guarantees to each  registered holder  of a FHLMC
Certificate ultimate collection of all principal of the related mortgage  loans,
without  any offset or deduction, but  does not, generally, guarantee the timely
payment of scheduled principal. FHLMC may remit the amount due on account of its
guarantee of collection of principal at any time after default on an  underlying
mortgage  loan, but not later than 30  days following (i) foreclosure sale, (ii)
payment of a claim by any mortgage insurer or (iii) the expiration of any  right
of  redemption, whichever occurs later, but in  any event no later than one year
after demand  has  been made  upon  the  mortgagor for  accelerated  payment  of
principal.  The obligations of FHLMC under  its guarantee are obligations solely
of FHLMC and are not backed by the full faith and credit of the U.S. Government.
 
    FHLMC Certificates represent  a pro  rata interest  in a  group of  mortgage
loans  (a  "FHLMC Certificate  group") purchased  by  FHLMC. The  mortgage loans
underlying the FHLMC Certificates will consist of fixed rate or adjustable  rate
mortgage  loans with original terms to maturity of between ten and thirty years,
substantially all of  which are secured  by first liens  on one- to  four-family
residential properties or multifamily projects. Each mortgage loan must meet the
applicable  standards set forth in the FHLMC  Act. A FHLMC Certificate group may
include whole  loans,  participation  interests in  whole  loans  and  undivided
interests in whole loans and participations comprising another FHLMC Certificate
group.
 
CORPORATE DEBT SECURITIES
 
    As  described  in  the  Prospectus, the  Fund  may  purchase  corporate debt
securities rated Aaa by Moody's  or AAA by S&P or,  if unrated, deemed to be  of
comparable  quality  by  the Fund's  Trustees.  These debt  securities  may have
adjustable or fixed rates of interest and in certain instances may be secured by
assets of the issuer. Adjustable rate corporate debt securities, which the  Fund
may purchase up to 5% of its total assets, may have features similar to those of
adjustable  rate  Mortgage-Backed  Securities,  but  corporate  debt securities,
unlike Mortgage-Backed Securities, are not subject to prepayment risk other than
through contractual  call  provisions  which  generally  impose  a  penalty  for
prepayment. Fixed rate debt securities also may be subject to call provisions.
 
MUNICIPAL OBLIGATIONS
 
    The  Fund may invest up  to 5% of its  total assets in Municipal Obligations
(consisting of Municipal Bonds, Municipal Notes and Municipal Commercial  Paper)
rated  in  the  highest  rating  category  by  Moody's  Investor  Service,  Inc.
("Moody's") or Standard & Poor's Corporation ("S&P"). The Municipal  Obligations
in  which the Fund  may invest include "zero  coupon" Municipal Obligations. Any
Municipal Obligation which depends directly or  indirectly on the credit of  the
United  States  Government shall  be considered  to have  the highest  rating by
Moody's and S&P.
 
                                       15
<PAGE>
    Municipal  Bonds and  Municipal Notes are  debt obligations of  a state, its
cities, municipalities and municipal  agencies which generally have  maturities,
at  the time of their issuance,  of either one year or  more (Bonds) or from six
months to three years (Notes). Municipal Commercial Paper consists of short-term
obligations of  municipalities  which  may  be issued  at  a  discount  and  are
sometimes  referred  to as  Short-Term Discount  Notes.  An obligation  shall be
considered a Municipal Bond, Municipal  Note or Municipal Commercial Paper  only
if,  in the opinion of bond counsel, the interest payable thereon is exempt from
federal income tax.
 
    The two principal classifications of  Municipal Bonds, Notes and  Commercial
Paper  are "general obligation" and "revenue"  bonds, notes or commercial paper.
General obligation bonds, notes or commercial paper are secured by the  issuer's
pledge  of its faith, credit  and taxing power for  the payment of principal and
interest. Issuers of general obligation bonds, notes or commercial paper include
a state,  its counties,  cities,  towns and  other governmental  units.  Revenue
bonds,  notes or commercial paper  are payable from the  revenues derived from a
particular facility or  class of  facilities or,  in some  cases, from  specific
revenue  sources. Revenue bonds, notes or commercial paper are issued for a wide
variety of purposes, including the financing  of electric, gas, water and  sewer
systems and other public utilities; industrial development and pollution control
facilities;   single  and  multi-family  housing  units;  public  buildings  and
facilities; air and marine ports, transportation facilities such as toll  roads,
bridges and tunnels; and health and educational facilities such as hospitals and
dormitories.  They rely primarily on user fees to pay debt service, although the
principal revenue source is often  supplemented by additional security  features
which  are intended to enhance the creditworthiness of the issuer's obligations.
In some cases, particularly revenue bonds  issued to finance housing and  public
buildings,  a direct or implied "moral obligation" of a governmental unit may be
pledged to the payment of debt service.  In other cases, a special tax or  other
charge may augment user fees.
 
    Included  within  the revenue  bonds  category are  participations  in lease
obligations or installment purchase  contracts (hereinafter collectively  called
"lease  obligations") of municipalities. State and local governments issue lease
obligations to acquire equipment and facilities.
 
    Lease obligations  may  have  risks not  normally  associated  with  general
obligation   or  other  revenue  bonds.   Leases  and  installment  purchase  or
conditional sale contracts (which may provide  for title to the leased asset  to
pass  eventually  to the  issuer)  have developed  as  a means  for governmental
issuers to acquire  property and  equipment without the  necessity of  complying
with  the constitutional and statutory requirements generally applicable for the
issuance of debt. Certain lease obligations contain "non-appropriation"  clauses
that  provide  that the  governmental issuer  has no  obligation to  make future
payments under  the lease  or contract  unless money  is appropriated  for  such
purpose  by  the appropriate  legislative body  on an  annual or  other periodic
basis.  Consequently,  continued  lease  payments  on  those  lease  obligations
containing  "non-appropriation"  clauses  are  dependent  on  future legislative
actions. If such  legislative actions  do not occur,  the holders  of the  lease
obligation  may  experience  difficulty in  exercising  their  rights, including
disposition of the property.
 
LENDING OF PORTFOLIO SECURITIES
 
    Consistent with applicable  regulatory requirements, the  Fund may lend  its
portfolio  securities  to  brokers, dealers  and  other  financial institutions,
provided that such loans are callable at any time by the Fund (subject to notice
provisions described  below), and  are at  all  times secured  by cash  or  cash
equivalents, which are maintained in a segregated account pursuant to applicable
regulations  and that are at least equal  to the market value, determined daily,
of the loaned securities. The advantage of such loans is that the Fund continues
to receive the income on  the loaned securities while  at the same time  earning
interest  on the cash amounts deposited as collateral, which will be invested in
short-term obligations. The Fund will not lend its portfolio securities if  such
loans  are not permitted  by the laws or  regulations of any  state in which its
shares are qualified for sale  and will not lend more  than 25% of the value  of
its  total assets. The Fund did not  lend any of its portfolio securities during
its fiscal year ended October 31, 1996.
 
                                       16
<PAGE>
    A loan may be terminated by the borrower on one business day's notice, or by
the Fund on  two business days'  notice. If  the borrower fails  to deliver  the
loaned  securities within two days after receipt  of notice, the Trust could use
the collateral to replace the securities  while holding the borrower liable  for
any  excess  of replacement  cost  over collateral.  As  with any  extensions of
credit, there are  risks of delay  in recovery and  in some cases  even loss  of
rights in the collateral should the borrower of the securities fail financially.
However,  these loans of portfolio securities will  only be made to firms deemed
by the Fund's management  to be creditworthy  and when the  income which can  be
earned  from such loans  justifies the attendant risks.  Upon termination of the
loan, the borrower is required to return the securities to the Fund. Any gain or
loss in the market  price during the  loan period would inure  to the Fund.  The
creditworthiness  of firms to which the Fund lends its portfolio securities will
be monitored  on  an  ongoing  basis  by  the  Investment  Manager  pursuant  to
procedures  adopted and reviewed, on an ongoing  basis, by the Board of Trustees
of the Fund.
 
    When voting or consent rights which accompany loaned securities pass to  the
borrower,  the Fund will follow the policy  of calling the loaned securities, to
be delivered within one day after notice, to permit the exercise of such  rights
if the matters involved would have a material effect on the Fund's investment in
such  loaned securities. The  Fund will pay  reasonable finder's, administrative
and custodial fees in connection with a loan of its securities.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    OPTIONS ON TREASURY BONDS  AND NOTES.  Because  trading interest in  options
written  on Treasury bonds and notes tends to center mostly on the most recently
auctioned issues, the exchanges on which such securities trade will not continue
indefinitely to  introduce  options with  new  expirations to  replace  expiring
options  on  particular  issues.  Instead,  the  expirations  introduced  at the
commencement of options  trading on a  particular issue will  be allowed to  run
their  course, with the possible addition of a limited number of new expirations
as the original ones  expire. Options trading  on each issue  of bonds or  notes
will  thus be phased  out as new options  are listed on  more recent issues, and
options representing  a  full  range  of  expirations  will  not  ordinarily  be
available for every issue on which options are traded.
 
    PURCHASING  CALL AND PUT OPTIONS.  As stated in the Prospectus, 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 put options on securities which it holds
(or  has the right to acquire) in its portfolio only to protect itself against a
decline in the value of  the security. If the  value of the underlying  security
were  to fall below the exercise price of the put purchased in an amount greater
than the premium paid for the option,  the Fund would incur no additional  loss.
In  addition, the Fund may  sell a put option  which it has previously purchased
prior to the sale of  the securities underlying such  option. Such a sale  would
result  in a net  gain or loss depending  on whether the  amount received on the
sale is more or less  than the premium and other  transaction costs paid on  the
put  option which is sold. Any such gain or  loss could be offset in whole or in
part by a change in the market value of the underlying security. If a put option
purchased by the Fund expired without being sold or exercised, the premium would
be lost.
 
    RISKS OF OPTIONS TRANSACTIONS.  In the  event of the bankruptcy of a  broker
through  which  the Fund  engages  in transactions  in  options, the  Fund could
experience delays and/or losses in liquidating open positions purchased or  sold
through  the broker and/or  incur a loss of  all or part  of its margin deposits
with the broker. Similarly, in the event  of the bankruptcy of the writer of  an
OTC  option purchased by  the Fund, the Fund  could experience a  loss of all or
part of the value of the option. Transactions are entered into by the Fund  only
with  brokers or  financial institutions  deemed creditworthy  by the Investment
Manager and the Sub-Advisor.
 
    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.
 
                                       17
<PAGE>
    INTEREST RATE FUTURES CONTRACTS.  As a purchaser of an interest rate futures
contract ("futures contract"), the Fund incurs an obligation to take delivery of
a  specified  amount of  the  obligation underlying  the  futures contract  at a
specified time in the  future for a  specified price. As a  seller of a  futures
contract,  the Fund incurs an obligation to  deliver the specified amount of the
underlying obligation at a specified time in return for an agreed upon price.
 
    The Fund will purchase or sell futures contracts for the purpose of  hedging
its   portfolio  (or  anticipated  portfolio)   securities  against  changes  in
prevailing interest  rates.  If  the  Investment  Manager  and  the  Sub-Advisor
anticipate  that interest rates  may rise and, concomitantly,  the price of U.S.
Government or other debt securities fall, the Fund may sell a futures  contract.
If  declining interest  rates are anticipated,  the Fund may  purchase a futures
contract to protect against a potential increase in the price of U.S. Government
or other debt securities the Fund intends to purchase. Subsequently, appropriate
U.S. Government or  other debt securities  may be  purchased by the  Fund in  an
orderly  fashion; as  securities are purchased,  corresponding futures positions
would be  terminated by  offsetting  sales of  contracts. In  addition,  futures
contracts  will be bought or sold in order to close out a short or long position
in a corresponding futures contract.
 
    As discussed  in the  Prospectus,  the Fund  may invest  in  Mortgage-Backed
Securities,  such  as  floating  rate CMOs  or  adjustable  rate Mortgage-Backed
Securities, which have interest  rates subject to  periodic adjustment based  on
changes  to a designated index. One index which may serve as such a benchmark is
the London Interbank Offered Rate, or LIBOR. In order for the Fund to hedge  its
exposure  to  fluctuations  in  short-term  interest  rates  for  its  portfolio
securities subject to  the LIBOR  rate, the Fund  may purchase  or sell  futures
contracts  on U.S. dollar denominated Eurodollar instruments linked to the LIBOR
rate.
 
    Although most futures contracts  call for actual  delivery or acceptance  of
securities,  the contracts  usually are  closed out  before the  settlement date
without the making or taking of delivery. A futures contract sale is closed  out
by  effecting a futures contract  purchase for the same  aggregate amount of the
specific type of security and the same delivery date. If the sale price  exceeds
the offsetting purchase price, the seller would be paid the difference and would
realize  a gain. If  the offsetting purchase  price exceeds the  sale price, the
seller would pay the difference and  would realize a loss. Similarly, a  futures
contract  purchase is closed  out by effecting  a futures contract  sale for the
same aggregate amount  of the specific  type of security  and the same  delivery
date.  If the  offsetting sale price  exceeds the purchase  price, the purchaser
would realize a gain, whereas if the purchase price exceeds the offsetting  sale
price,  the purchaser would realize a loss.  There is no assurance that the Fund
will be able to enter into a closing transaction.
 
    When the Fund  enters into a  futures contract it  is initially required  to
deposit  with its Custodian, in  a segregated account in  the name of the broker
performing the  transaction  an "initial  margin"  of cash  or  U.S.  Government
securities  or other liquid portfolio securities  equal to approximately 2-3% of
the  contract  amount.  Initial  margin  requirements  are  established  by  the
Exchanges  on which futures contracts trade and  may, from time to time, change.
In addition,  brokers may  establish margin  deposit requirements  in excess  of
those required by the Exchanges.
 
    Initial   margin  in  futures  transactions  is  different  from  margin  in
securities transactions in that initial margin does not involve the borrowing of
funds by a brokers' client but is,  rather, a good faith deposit on the  futures
contract  which will be returned to the  Fund upon the proper termination of the
futures contract. The margin  deposits made are marked  to market daily and  the
Fund  may be required  to make subsequent deposits  into the segregated account,
maintained at  its  Custodian for  that  purpose,  of cash  or  U.S.  Government
securities  or other liquid portfolio  securities, called "variation margin", in
the name  of the  broker, which  are  reflective of  price fluctuations  in  the
futures contract. Currently, interest rate futures contracts can be purchased on
debt  securities such as U.S. Treasury  Bills and Bonds, Eurodollar instruments,
U.S.  Treasury  Notes  with  Maturities  between  6  1/2  and  10  years,   GNMA
Certificates and Bank Certificates of Deposit.
 
                                       18
<PAGE>
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase call and put options on
futures  contracts  which  are traded  on  an  Exchange and  enter  into closing
transactions with respect to such options to terminate an existing position.  An
option  on a futures contract  gives the purchaser the  right (in return for the
premium paid), and the writer the obligation, to assume a position in a  futures
contract  (a long position if the  option is a call and  a short position if the
option is a put) at  a specified exercise price at  any time during the term  of
the option. Upon exercise of the option, the delivery of the futures position by
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 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 and
the Sub-Advisor wished to protect against an increase in interest rates and  the
resulting  negative impact  on the  value of  a portion  of its  U.S. Government
securities portfolio, it might purchase a put 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.
 
    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.
 
    RISKS  OF TRANSACTIONS IN FUTURES CONTRACTS  AND RELATED OPTIONS.  As stated
in the Prospectus, the Fund may sell  a futures contract to protect against  the
decline in the value of U.S. Government securities held by the Fund. However, it
is possible that the futures market may advance and the value of securities held
in  the Fund's portfolio may decline. If this were to occur, the Fund would lose
money on the futures  contracts and also  experience a decline  in value in  its
portfolio securities. However, while this could occur for a very brief period or
to  a very  small degree,  over time the  market prices  of the  securities of a
diversified portfolio will tend to move in  the same direction as the prices  of
futures contracts.
 
    If  the Fund purchases a  futures contract to hedge  against the increase in
value of U.S. Government  securities it intends  to buy, and  the value of  such
securities  decreases,  then  the  Fund  may  determine  not  to  invest  in the
securities as planned and will  realize a loss on  the futures contract that  is
not offset by a reduction in the price of the securities.
 
    If  the Fund maintains a short position in 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  liquid portfolio securities equal in
value (when added to any initial or  variation margin on deposit) to the  market
value  of the  securities underlying the  futures contract. Such  a position may
also be covered by owning the securities underlying the futures contract, or  by
holding  a call option  permitting the Fund  to purchase the  same contract at a
price no higher than the price at which the short position was established.
 
    In addition, if the  Fund holds a  long position in  a futures contract,  it
will  hold cash, U.S. Government securities or other high grade debt obligations
equal to the  purchase price  of the  contract (less  the amount  of initial  or
variation  margin on deposit) in a segregated account maintained for the Fund by
its Custodian.  Alternatively,  the  Fund  could  cover  its  long  position  by
purchasing  a put option on the same  futures contract with an exercise price as
high or higher than the price of the contract held by the Fund.
 
    Exchanges limit the amount by which the price of a futures contract may move
on any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures
 
                                       19
<PAGE>
position until the daily limit moves have ceased. In the event of adverse  price
movements, the Fund would continue to be required to make daily cash payments of
variation  margin on open futures positions. In such situations, if the Fund has
insufficient cash,  it may  have  to sell  portfolio  securities to  meet  daily
variation margin requirements at a time when it may be disadvantageous to do so.
In  addition,  the  Fund  may  be  required to  take  or  make  delivery  of the
instruments underlying interest rate futures contracts  it holds at a time  when
it  is disadvantageous to do so. The  inability to close out options and futures
positions could also have an adverse impact on the Fund's ability to effectively
hedge its portfolio.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in futures  or options  thereon, the Fund  could experience  delays
and/or losses in liquidating open positions purchased or sold through the broker
and/or  incur a  loss of  all or part  of its  margin deposits  with the broker.
Transactions are  entered  into  by  the Fund  only  with  broker  or  financial
institutions deemed creditworthy by the Investment Manager and the Sub-Advisor.
 
    While the futures contracts and options transactions to be engaged in by the
Fund  for  the  purpose  of  hedging the  Fund's  portfolio  securities  are not
speculative in nature, there are risks inherent in the use of such  instruments.
One  such risk which may arise in employing futures contracts to protect against
the price volatility of  portfolio securities is that  the prices of  securities
subject  to  futures contracts  (and thereby  the  futures contract  prices) may
correlate imperfectly  with  the behavior  of  the  cash prices  of  the  Fund's
portfolio  securities. Another such risk is that prices of interest rate futures
contracts may not move in tandem  with the changes in prevailing interest  rates
against which the Fund seeks a hedge. A correlation may also be distorted by the
fact  that  the futures  market is  dominated by  short-term traders  seeking to
profit from the difference  between a contract or  security price objective  and
their  cost of  borrowed funds. Such  distortions are generally  minor and would
diminish as the contract approached maturity.
 
    As stated  in  the Prospectus,  there  may exist  an  imperfect  correlation
between  the price movements of futures contracts  purchased by the Fund and the
movements in the prices of the securities which are the subject of the hedge. If
participants in the futures  market elect to close  out their contracts  through
offsetting   transactions   rather  than   meet  margin   deposit  requirements,
distortions in the normal relationships between the debt securities and  futures
market could result. Price distortions could also result if investors in futures
contracts  opt to  make or  take delivery  of underlying  securities rather than
engage in closing transactions due to  the resultant reduction in the  liquidity
of the futures market. In addition, due to the fact that, from the point of view
of speculators, the deposit requirements in the futures markets are less onerous
than  margin  requirements  in  the  cash  market,  increased  participation  by
speculators in the futures market  could cause temporary price distortions.  Due
to the possibility of price distortions in the futures market and because of the
imperfect  correlation  between  movements  in  the  prices  of  U.S. Government
securities and movements in the prices of futures contracts, a correct  forecast
of  interest rate  trends by the  Investment Manager  may still not  result in a
successful hedging transaction.
 
    There is no assurance that a liquid secondary market will exist for  futures
contracts  and related  options in  which the  Fund may  invest. In  the event a
liquid market does  not exist, it  may not be  possible to close  out a  futures
position,  and in the event of adverse  price movements, the Fund would continue
to be required  to make daily  cash payments of  variation margin. In  addition,
limitations  imposed by an exchange or board of trade on which futures contracts
are traded may compel or prevent the Fund from closing out a contract which  may
result  in reduced gain or  increased loss to the Fund.  The absence of a liquid
market in futures contracts might cause the Fund to make or take delivery of the
underlying securities at a time when it may be disadvantageous to do so.
 
    Compared to the purchase or sale of futures contracts, the purchase of  call
or  put options on  futures contracts involves  less potential risk  to the Fund
because the maximum amount  at risk is  the premium paid  for the options  (plus
transaction  costs). However, there may be  circumstances when the purchase of a
call or put  option on a  futures contract would  result in a  loss to the  Fund
notwithstanding that the purchase or sale of a futures contract would not result
in  a loss, as in the  instance where there is no  movement in the prices of the
futures contracts or underlying U.S. Government securities.

REPURCHASE AGREEMENTS
 
    When cash may be available  for only a few days,  it may be invested by  the
Fund in repurchase agreements until such time as it may otherwise be invested or
used  for payments of  obligations of the  Fund. These agreements,  which may be
viewed as  a  type  of  secured  lending by  the  Fund,  typically  involve  the
acquisition  by the Fund of debt securities from a selling financial institution
such as a  bank, savings and  loan association or  broker-dealer. The  agreement
provides  that  the  Fund  will  sell back  to  the  institution,  and  that the
institution  will  repurchase,  the  underlying  security  ("collateral")  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
value of the collateral, as specified in the agreement, does not decrease  below
the  purchase price plus  accrued interest. If  such decrease occurs, additional
collateral will  be  requested and,  when  received,  added to  the  account  to
maintain  full  collateralization.  The  Fund  will  accrue  interest  from  the
institution until the time when the  repurchase is to occur. Although such  date
is  deemed by the  Fund to be the  maturity date of  a repurchase agreement, the
maturities of securities subject to repurchase agreements are not subject to any
limits.
 
    While repurchase agreements involve certain risks not associated with direct
investment in debt securities, the Fund follows procedures designed to  minimize
such risks. These procedures include effecting repurchase transactions only with
large,   well-capitalized  and  well-established  financial  institutions  whose
financial condition will be continually monitored by the Investment Manager  and
Sub-Advisor  subject to procedures  established by the Board  of 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. It
is the current policy of the Fund not to invest in repurchase agreements that do
not  mature within seven  days if any  such investment, together  with any other
illiquid assets held by the Fund, amounts to more than 10% of its total assets.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
 
    As discussed in the Prospectus, from time to time, in the ordinary course of
business, the Fund may purchase securities on a when-issued or delayed  delivery
basis  -- i.e., delivery  and payment can take  place a month  or more after the
date of the  transactions. The  securities so  purchased are  subject to  market
fluctuation  and no interest accrues to  the purchaser during this period. While
the Fund will  only purchase securities  on a when-issued,  delayed delivery  or
forward  commitment basis  with the intention  of acquiring  the securities, the
Fund may  sell  the securities  before  the settlement  date,  if it  is  deemed
advisable. At the time the Fund makes the commitment to purchase securities on a
when-issued  or delayed delivery basis, the Fund will record the transaction and
thereafter reflect the value, each day, of such security in determining the  net
asset  value of the Fund.  At the time of delivery  of the securities, the value
may be more  or less than  the purchase price.  The Fund will  also establish  a
segregated  account with the Fund's custodian bank in which it will continuously
maintain cash, U.S. Government securities  or other liquid portfolio  securities
equal  in  value  to  commitments  for  such  when-issued  or  delayed  delivery
securities; subject to  this requirement,  the Fund may  purchase securities  on
such  basis without limit.  An increase in  the percentage of  the Fund's assets
committed to the  purchase of securities  on a when-issued  or delayed  delivery
basis  may increase the volatility of the Fund's net asset value. The Investment
Manager and the Sub-Advisor and  the Board of Trustees  do not believe that  the
Fund's  net asset value or income will  be adversely affected by its purchase of
securities on such basis.
 
PORTFOLIO TURNOVER
 
    The Fund may sell portfolio securities without regard to the length of  time
they  have been held whenever such sale  will, in the opinions of the Investment
Manager and the Sub-Advisor,  strengthen the Fund's  position and contribute  to
its  investment  objective.  As  a result  of  the  Fund's  investment objective
 
                                       21
<PAGE>
and policies, and the nature of the Mortgage-Backed Securities and  Asset-Backed
Securities  markets, the Fund's portfolio turnover  rate may exceed 200%. During
the fiscal years ended October 31, 1995 and 1996, the Fund's portfolio  turnover
rates were 366% and 265%, respectively.
 
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 (including limited
    partnership interests), 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.  Purchase  securities  of  other  investment  companies,  except  in
    connection  with a  merger, consolidation, reorganization  or acquisition of
    assets.  For  this  purpose,  Mortgage-Backed  Securities  and  Asset-Backed
    Securities are not deemed to be investment companies.
 
         4. Issue senior securities as defined in the Act, except insofar as the
    Fund  may  be deemed  to have  issued a  senior security  by reason  of: (a)
    entering into any reverse repurchase agreement or dollar roll; (b) borrowing
    money or  other leveraging;  or (c)  purchasing any  securities on  a  when-
    issued, delayed delivery or forward commitment basis.
 
         5.  Make loans of money  or securities, except: (a)  by the purchase of
    portfolio securities  in  which the  Fund  may invest  consistent  with  its
    investment  objective  and  policies;  (b) by  investment  in  repurchase or
    reverse purchase agreements; or (c) by lending its portfolio securities.
 
         6. 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.
 
         7.  Invest for the  purpose of exercising control  or management of any
    other issuer.
 
         8. Make short sales of securities or maintain a short position.
 
         9. Invest in securities of any issuer if, to the knowledge of the Fund,
    any officer or trustee of the Fund,  or any officer, director or partner  of
    the  Investment  Manager or  Sub-Advisor owns  more  than 1/2  of 1%  of the
    outstanding voting 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 voting 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 the foregoing restrictions.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject to  the  general  supervision  of the  Trustees  of  the  Fund,  the
Investment  Manager  and  the  Sub-Advisor are  responsible  for  the investment
decisions and the placing of the orders for portfolio transactions for the Fund.
The  Fund's   portfolio  transactions   will  occur   primarily  with   issuers,
underwriters  or  major  dealers  acting as  principals.  Such  transactions are
normally on a net basis and do not involve payment of brokerage commissions. The
cost of securities purchased from an underwriter usually
 
                                       22
<PAGE>
includes a commission paid by the issuer to the underwriters; transactions  with
dealers  normally reflect the  spread between bid and  asked prices. Options and
futures transactions will usually be effected through a broker and a  commission
will be charged. During the fiscal years ended October 31, 1996, 1995, and 1994,
the Fund did not pay any brokerage commissions.
 
    The  Investment Manager  and the  Sub-Advisor currently  serve 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  and  the   Sub-Advisor  to  cause  purchase  or   sale
transactions  to be allocated among the Fund  and others whose assets it manages
in such manner as it deems equitable. In making such allocations among the  Fund
and  other client  accounts, various  factors may  be considered,  including the
respective investment objectives, the relative size of portfolio holdings of the
same or comparable securities, the availability of cash for investment, the size
of investment  commitments  generally  held  and the  opinions  of  the  persons
responsible  for managing the portfolios of  the Fund and other client accounts.
In the case of  certain initial and secondary  public offerings, the  Investment
Manager  may utilize a pro-rata allocation process based on the size of the Dean
Witter Funds  involved  and the  number  of  shares available  from  the  public
offering.
 
    The  policy  of the  Fund regarding  purchases and  sales of  securities and
futures contracts for its portfolio is that primary consideration will be  given
to  obtaining the most favorable prices and efficient execution of transactions.
In seeking to  implement the  Fund's policies,  the Investment  Manager and  the
Sub-Advisor   effect  transactions  with  those  brokers  and  dealers  who  the
Investment Manager and the Sub-Advisor believe provide the most favorable prices
and are capable of providing efficient executions. If the Investment Manager  or
the  Sub-Advisor believes such price and execution are obtainable from more than
one  broker  or  dealer,  it   may  give  consideration  to  placing   portfolio
transactions  with those brokers and dealers who also furnish research and other
services to the  Fund or  the Investment  Manager and/or  the Sub-Advisor.  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 and  the
Sub-Advisor from brokers and dealers may be of benefit to the Investment Manager
and  the Sub-Advisor in the management of  accounts of some of its other clients
and may not in all  cases benefit the Fund directly.  While the receipt of  such
information and services is useful in varying degrees and would generally reduce
the amount of research or services otherwise performed by the Investment Manager
and  the Sub-Advisor  and thereby reduce  its expenses, it  is of indeterminable
value and the fees paid  to the Investment Manager  and the Sub-Advisor are  not
reduced by any amount that may be attributable to the value of such services.
 
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect  principal transactions in certain money market instruments with DWR. The
Fund will limit  its transactions  with DWR  to U.S.  Government and  Government
Agency  Securities, Bank  Money Instruments  (I.E., Certificates  of Deposit and
Bankers' Acceptances) and Commercial Paper.  Such transactions will be  effected
with  DWR only when the  price available from DWR  is better than that available
from other dealers. During the fiscal year ended October 31, 1996, the Fund  did
not effect any principal transactions with DWR.
 
    Consistent  with  the  policy  described  above,  brokerage  transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR. In order for DWR to effect portfolio transactions for  the
Fund,  the  commissions, fees  or  other remuneration  received  by DWR  must be
reasonable and fair compared to the commissions, fees or other remuneration paid
to other brokers  in connection with  comparable transactions involving  similar
securities  being purchased or sold on an exchange during a comparable period of
time. This standard  would allow DWR  to receive no  more than the  remuneration
which  would  be  expected  to  be  received  by  an  unaffiliated  broker  in a
commensurate arm's-length transaction.  Furthermore, the Trustees  of the  Fund,
including  a majority  of the Trustees  who are not  "interested" Trustees, have
adopted  procedures  which   are  reasonably  designed   to  provide  that   any
commissions,  fees or  other remuneration  paid to  DWR are  consistent with the
foregoing standard.

THE DISTRIBUTOR
- --------------------------------------------------------------------------------
 
    As  discussed in the Prospectus, shares of  the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"). The Distributor has entered into a
selected dealer agreement  with DWR,  which through its  own sales  organization
sells  shares of the Fund. In addition,  the Distributor may enter into selected
dealer  agreements  with  other  selected  broker-dealers.  The  Distributor,  a
Delaware  corporation, is a wholly-owned subsidiary of DWDC. The Trustees of the
Fund, including a majority of the Trustees who are not, and were not at the time
they voted,  interested  persons  of  the  Fund, as  defined  in  the  Act  (the
"Independent  Trustees"), approved, at  their meeting held  on October 30, 1992,
the current  Distribution  Agreement  appointing the  Distributor  as  exclusive
distributor  of  the Fund's  shares and  providing for  the Distributor  to bear
distribution expenses not borne by the Fund. The current Distribution  Agreement
took effect on June 30, 1993, upon the spin-off by Sears, Roebuck and Co. of its
remaining  shares of DWDC.  The current Distribution  Agreement is substantively
identical  to  the  Fund's  previous  distribution  agreement  in  all  material
respects,  except for the dates of effectiveness. By its terms, the Distribution
Agreement had an initial term ending April  30, 1994, and provides that it  will
remain  in effect  from year  to year  thereafter if  approved by  the Trustees,
including a majority of the Independent Trustees.
 
    The Distributor bears all expenses it may incur in providing services  under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor  also pays certain  expenses in connection  with the distribution of
the Fund's shares, including the  costs of preparing, printing and  distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses  and supplements thereto  used in connection  with the offering and
sale of the  Fund's shares.  The Fund bears  the costs  of initial  typesetting,
printing   and  distribution   of  prospectuses   and  supplements   thereto  to
shareholders. The Fund  also bears  the costs of  registering the  Fund and  its
shares  under federal  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"). The Plan was approved  by the Trustees on April 16, 1991,  and
by  DWR  as  the  Fund's then  sole  shareholder  on  May 15,  1991  and  by the
shareholders holding  a majority,  as defined  in the  Act, of  the  outstanding
voting  securities of the Fund at a  Special Meeting of Shareholders of the Fund
held on June 29, 1992. 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 DWR  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.
At  their meeting held on October 30,  1992, the Trustees of the Fund, including
all of the independent 12b-1 Trustees,  approved certain amendments to the  Plan
which  took effect in January,  1993 and were designed  to reflect the fact that
upon the  reorganization  described  above, the  share  distribution  activities
theretofore  performed for the Fund  by DWR were assumed  by the Distributor and
DWR's sales  activities are  now being  performed  pursuant to  the terms  of  a
selected  dealer  agreement  between  the Distributor  and  DWR.  The amendments
provide that payments under the Plan will be made to the Distributor rather than
to DWR as before the amendment, and  that the Distributor in turn is  authorized
to
 
                                       24
<PAGE>
make payments to DWR, its affiliates or other selected broker-dealers (or direct
that the Fund pay such entities directly). The Distributor is also authorized to
retain  part  of  such  fee as  compensation  for  its  own distribution-related
expenses.
 
    The Fund is authorized  to reimburse the  Distributor for specific  expenses
the  distributor incurs or plans  to incur in promoting  the distribution of the
Fund's shares.  Reimbursement  is  made  through  monthly  payments  in  amounts
determined  in  advance of  each  fiscal quarter  by  the Trustees,  including a
majority of the Independent 12b-1 Trustees.  The amount of each monthly  payment
may  in no event exceed an amount equal to  a payment at the annual rate of 0.20
of 1% of  the average  daily net assets  of the  shares of the  Fund during  the
month.  Such payment  is treated by  the Fund  as an expense  in the  year it is
accrued. No  interest  or  other  financing charges  will  be  incurred  by  the
Distributor  for which  reimbursement payments under  the Plan will  be made. In
addition, no  interest charges,  if any,  incurred on  any distribution  expense
incurred by the Distributor pursuant to the Plan, will be reimbursable under the
Plan.
 
    The  Distributor has informed the Fund that the fee payable by the Fund each
year pursuant to the Plan not to exceed to 0.20% of the Fund's average daily net
assets is characterized as a "service fee"  under the Rules of Fair Practice  of
the  National Association of Securities Dealers,  Inc. (of which the Distributor
is a  member).  The fee  is  a payment  made  for personal  service  and/or  the
maintenance 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.
 
    For the fiscal year ended October 31, 1996, the Fund paid a total of $51,691
pursuant to the Plan. Such  payment amounted to an annual  rate of 0.18% of  the
Fund's average daily net assets for such fiscal period. It is estimated that the
amount  paid  by the  Fund for  distribution  was for  expenses which  relate to
compensation  of  sales   personnel  and  associated   overhead  expenses.   The
Distributor has informed the Fund that it received sales charges on sales of the
Fund's  shares in the approximate amounts of $19,200, $6,600 and $38,766 for the
fiscal years ended 1994, 1995 and 1996, respectively.
 
    The Plan has an initial term which  ended April 30, 1992, and provides  that
from  year  to  year  thereafter  it  will  continue  in  effect,  provided such
continuance is approved annually by a vote of the Trustees, including a majority
of the Independent 12b-1 Trustees. Most  recent continuance of the Plan for  one
year,  until April 30, 1997, was approved by  the Board of Trustees of the Fund,
including a majority of the Independent 12b-1 Trustees, at a Board meeting  held
on  April 17, 1996. At  that meeting, the Trustees,  including a majority of the
Independent 12b-1 Trustees,  also approved certain  technical amendments to  the
Plan in connection with recent amendments adopted by the National Association of
Securities  Dealers, Inc. to its Rules of  Fair Practice. Prior to approving the
continuation  of  the  Plan,  the  Trustees  requested  and  received  from  the
Distributor  and reviewed  all the  information which  they deemed  necessary to
arrive at an informed determination.  In making their determination to  continue
the  Plan, the Trustees considered: (1) the Fund's experience under the Plan and
whether such experience indicates that the Plan is operating as anticipated: (2)
the benefits the Fund had obtained, was obtaining and would be likely to  obtain
under  the Plan; and (3) what services  had been provided and were continuing to
be provided under the Plan  to the Fund and  its shareholders. Based upon  their
review,  the  Trustees of  the  Fund, including  each  of the  independent 12b-1
Trustees, determined that continuation of the Plan would be in the best interest
of the Fund and would have a reasonable likelihood of continuing to benefit  the
Fund  and its shareholders. In the Trustees'  quarterly review of the Plan, they
will consider  its  continued  appropriateness and  the  level  of  compensation
provided  herein.  An  amendment  to  increase  materially  the  maximum  amount
authorized to be spent under the Plan  and Agreement on behalf of the Fund  must
be  approved by the shareholders of the Fund, and all material amendments to the
Plan must be approved by  the Trustees in the  manner described above. The  Plan
may  be terminated  on behalf of  the Fund at  any time, without  payment of any
penalty,   by    vote    of    the    holders   of    a    majority    of    the
 
                                       25
<PAGE>
Independent  12b-1 Trustees or by a vote of a majority of the outstanding voting
securities of the Fund (as defined in the Act) on not more than 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.
 
    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  incremental  distribution expenses
incurred by the Distributor  on behalf 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 consider  its  continued  appropriateness and  the  level  of  compensation
provided therein.
 
    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, had any direct or indirect
financial interest in the operation  of the Plan except  to the extent that  the
Investment  Manager 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 Fund.
 
REDUCED SALES CHARGE
 
    RIGHT  OF  ACCUMULATION.   As  discussed  in the  Prospectus,  investors may
combine the  current value  of  shares purchased  in separate  transactions  for
purposes  of benefitting from the reduced  sales charges available for purchases
of shares  of the  Fund totalling  at least  $100,000 in  net asset  value.  For
example,  if any person or entity who  qualifies for this privilege holds shares
of the  Fund  having  a  current  value of  $25,000  and  purchases  $75,000  of
additional  shares  of the  Fund,  the sales  charge  applicable to  the $75,000
purchase would be 2.50% of the offering price.
 
    The Distributor must  be notified by  the dealer or  the shareholder at  the
time  a purchase  order is  placed that the  purchase qualifies  for the reduced
charge under the  Right of Accumulation.  Similar notification must  be made  in
writing  by the dealer or shareholder when such  an order is placed by mail. The
reduced sales  charge will  not be  granted  if: (a)  such notification  is  not
furnished  at the  time of  the order;  or (b)  a review  of the  records of the
Distributor or Dean Witter Trust Company (the "Transfer Agent") fails to confirm
the investor's represented holdings.
 
    LETTER OF INTENT.  As discussed in the prospectus under the caption "Reduced
Sales Charges," reduced sales charges are available to investors who enter  into
a  written Letter of Intent providing  for the purchase, within a thirteen-month
period, of shares of the Fund from the Distributor or from a single dealer which
has entered into a Selected Dealer Agreement with the Distributor.
 
    A Letter of Intent permits an investor to establish a total investment  goal
to  be achieved by  any number of  purchases over a  thirteen-month period. Each
purchase made  during  the period  will  receive the  reduced  sales  commission
applicable  to  the amount  represented  by the  goal, as  if  it were  a single
purchase. A number of shares  equal in value to 5%  of the dollar amount of  the
Letter  of Intent will be held  in escrow by the Transfer  Agent, in the name of
the shareholder. The initial purchase under a Letter of Intent must be equal  to
at least 5% of the stated investment goal.
 
    The  Letter of Intent  does not obligate  the Investor to  purchase, nor the
Fund to sell, the indicated  amount. In the event the  Letter of Intent goal  is
not  achieved within the thirteen-month period,  the investor is required to pay
the difference between the  sales charge otherwise  applicable to the  purchases
made  during this period  and sales charges  actually paid. Such  payment may be
made directly to the Distributor or, if not paid, the Distributor is  authorized
by  the shareholder  to liquidate  a sufficient  number of  his or  her escrowed
shares to obtain such difference.
 
    If the goal is exceeded and purchases pass the next sales charge level,  the
sales  charge on the entire amount of  the purchase that results in passing that
level and  on subsequent  purchases will  be subject  to further  reduced  sales
charges  in the same manner as set  forth above under RIGHT OF ACCUMULATION, but
there will be no retroactive reduction of sales charges on previous purchases.
 
                                       26
<PAGE>
    At any time while  a Letter of  Intent is in effect,  a shareholder may,  by
written  notice to the Distributor,  increase the amount of  the stated goal. In
that event, only shares  purchased during the previous  90-day period and  still
owned by the shareholder will be included in the new sales charge reduction. The
5% escrow and minimum purchase requirements will be applicable to the new stated
goal.  Investors electing to purchase shares of the Fund pursuant to a Letter of
Intent should carefully read such Letter of Intent.
 
DETERMINATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------
 
    As stated  in  the Prospectus,  short-term  debt securities  with  remaining
maturities of sixty days or less at the time of purchase are valued at amortized
cost, unless the Trustees determine such does not reflect the securities' market
value,  in which  case these securities  will be  valued at their  fair value as
determined by the Trustees. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach a remaining maturity of sixty
days, whereupon they will be valued at  amortized cost using their value on  the
61st  day unless  the Trustees determine  such does not  reflect the securities'
market value, in which case these securities will be valued at their fair  value
as  determined by  the Trustees.  Listed options are  valued at  the latest sale
price on the exchange on which they  are listed unless no sales of such  options
have taken place that day, in which case they will be valued at the mean between
their  latest bid  and asked  prices. Unlisted  options are  valued at  the mean
between their latest bid and asked prices. Futures are valued at the latest sale
price on  the commodities  exchange  on which  they  trade unless  the  Trustees
determine  such price does  not reflect their  market value, in  which case they
will be valued  at their fair  value as  determined by the  Trustees. All  other
securities and other assets are valued at their fair value as determined in good
faith under procedures established by and under the supervision of the Trustees.
 
    The  net asset value per share of the  Fund is determined once daily at 4:00
p.m., New York time on each day that the New York Stock Exchange is open or,  on
days when the New York Stock Exchange closes prior to 4:00 p.m., at such earlier
time  and on each other day in which  there is a sufficient degree of trading in
the Fund's investments to affect the net asset value, except that the net  asset
value  may not be  computed on a  day on which  no orders have  been received to
purchase, or tenders to sell or redeem, Fund shares, by taking the value of  all
assets  of  the Fund,  subtracting its  liabilities, dividing  by the  number of
shares outstanding  and  adjusting to  the  nearest  cent. 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 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  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 another selected
broker-dealer.
 
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  Any  shareholder
who  receives a cash payment representing  a dividend or distribution may invest
such dividend  or distribution  at the  net asset  value next  determined  after
receipt  by the  Transfer Agent,  without the imposition  of a  sales charge, by
returning the check  or the proceeds  to the Transfer  Agent within thirty  days
after the payment date. If the shareholder returns the proceeds of a dividend or
distribution,  such funds must  be accompanied by  a signed statement indicating
that the proceeds  constitute a dividend  or distribution to  be invested.  Such
investment  will be made at the net  asset value per share next determined after
receipt of the check or proceeds by the Transfer Agent.
 
                                       27
<PAGE>
    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 offering  price.
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.
 
    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.
 
    Withdrawal  plan payments should  not be considered  as dividends, yields or
income. If periodic withdrawal plan payments continuously exceed net  investment
income  and net  capital gains,  the shareholder's  original investment  will be
correspondingly reduced and ultimately exhausted.
 
    Each withdrawal constitutes  a redemption  of shares  and any  gain or  loss
realized  must  be  recognized for  federal  income tax  purposes.  Although the
shareholder may  make  additional  investments  of  $2,500  or  more  under  the
Systematic  Withdrawal  Plan, withdrawals  made  concurrently with  purchases of
additional shares are inadvisable because of the sales charges applicable to the
purchase of additional shares.
 
    Any shareholder who wishes to have  payments under the Withdrawal Plan  made
to  a third party or sent to an address other than the one listed on the account
must send complete written instructions to  the Transfer Agent to enroll in  the
Withdrawal  Plan.  The  shareholder's  signature on  such  instructions  must be
guaranteed  by  an   eligible  guarantor  acceptable   to  the  Transfer   Agent
(shareholders  should  contact  the Transfer  Agent  for a  determination  as to
whether a particular institution is  such an eligible guarantor). A  shareholder
may,  at any time, change the amount and interval of withdrawal payments through
his or her Account Executive or  by written notification to the Transfer  Agent.
In  addition, the  party and/or the  address to  which checks are  mailed may be
changed by written notification to the Transfer Agent, with signature guarantees
required in the manner described above.  The shareholder may also terminate  the
Withdrawal  Plan at  any time by  written notice  to the Transfer  Agent. In the
event  of  such  termination,  the  account  will  be  continued  as  a  regular
shareholder  investment account. The shareholder may  also redeem all or part of
the  shares  held  in  the   Withdrawal  Plan  account  (see  "Redemptions   and
Repurchases" in the Prospectus) at any time.
 
    DIRECT  INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
a shareholder may  make additional  investments in Fund  shares at  any time  by
sending  a  check in  any amount,  not less  than $100,  payable to  Dean Witter
Premier Income Trust, directly to the  Fund's Transfer Agent. Such amounts  will
be  applied to the purchase of Fund shares at the net asset value per share next
computed after receipt of the check  or purchase payment by the Transfer  Agent.
The shares so purchased will be credited to the investor's account.
 
    EXCHANGE  PRIVILEGE.    As  discussed  in  the  Prospectus,  the  Fund makes
available to its shareholders an Exchange Privilege whereby shareholders of  the
Fund  may exchange their shares for shares  of other Dean Witter FESC Funds, for
shares of Dean Witter CDSC Funds, and for shares of Dean Witter Short-Term  U.S.
Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean Witter Short-Term
Bond  Fund, Dean Witter Balanced Growth  Fund, Dean Witter Balanced Income Fund,
Dean Witter Intermediate Term  U.S. Treasury Trust, and  five Dean Witter  Funds
which   are  money  market  funds  (the  foregoing  eleven  non-CDSC  funds  are
hereinafter referred to as  the "Exchange Funds"). Exchanges  may be made  after
the  shares of the CDSC fund or FESC  fund acquired by purchase (not by exchange
or dividend reinvestment) have  been held for thirty  days. There is no  holding
period  for exchanges of  shares acquired by  exchange or dividend reinvestment.
However, shares of CDSC funds, including shares acquired in exchange for  shares
of FESC funds, may not be exchanged for shares of FESC funds. Thus, shareholders
who  exchange  their  Fund shares  for  shares  of CDSC  funds  may subsequently
exchange
 
                                       28
<PAGE>
those shares  for shares  of other  CDSC funds  or Exchange  Funds but  may  not
reacquire  FESC fund shares by exchange. An exchange will be treated for federal
income tax purposes the same as a  repurchase or redemption of shares, on  which
the shareholder may realize a capital gain or loss.
 
    Any  new account  established through the  Exchange Privilege  will have the
same registration and cash dividend or dividend reinvestment plan as the present
account,  unless  the  Transfer  Agent  receives  written  notification  to  the
contrary.  For  telephone  exchanges,  the exact  registration  of  the existing
account and the account number must be provided.
 
    Any shares  held  in  certificate  form cannot  be  exchanged  but  must  be
forwarded  to the  Transfer Agent and  deposited into  the shareholder's account
before being eligible for exchange.  (Certificates mailed in for deposit  should
not be endorsed).
 
    The  Transfer Agent acts as agent for  shareholders of the Fund in effecting
redemptions of Fund shares and in applying the proceeds to the purchase of other
fund shares. In  the absence  of negligence on  its part,  neither the  Transfer
Agent  nor the Fund shall be liable for  any redemption of Fund shares caused by
unauthorized telephone instructions.  Accordingly, in such  event, the  investor
shall bear the risk of loss. The staff of the Securities and Exchange Commission
is currently considering the propriety of such a policy.
 
    With  respect to  the redemption  or repurchase of  shares of  the Fund, the
application of proceeds to the purchase of  new shares in the Fund or any  other
of  the  funds and  the general  administration of  the Exchange  Privilege, the
Transfer Agent  acts as  agent for  the Distributor  and for  the  shareholder's
selected  broker-dealer,  if  any, in  the  performance of  such  functions. 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  is $5,000 for  Dean Witter Special  Value Fund.  The
minimum  initial  investment  for all  other  Dean  Witter Funds  for  which the
Exchange Privilege is available is $1,000.) Upon exchange into an Exchange Fund,
the shares of that  fund will be  held in a  special Exchange Privilege  Account
separately  from accounts of  those shareholders who  have acquired their shares
directly from that  fund. As a  result, certain services  normally available  to
shareholders  of those funds,  including the check writing  feature, will not be
available for funds held in that account.
 
    The Fund and each  of the other  Dean Witter Funds may  limit the number  of
times  this  Exchange  Privilege  may  be exercised  by  any  investor  within a
specified period of  time. Also,  the Exchange  Privilege may  be terminated  or
revised  at any time by the  Fund and/or any of the  Dean Witter Funds for which
shares of the Fund have been exchanged,  upon such notice as may be required  by
applicable  regulatory agencies (presently  sixty days prior  written 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 an
Exchange Fund pursuant to the Exchange  Privilege and provided further that  the
Exchange  Privilege may  be terminated or  materially revised  without notice at
times (a) when the New York Stock Exchange is
 
                                       29
<PAGE>
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(s),
policies and restrictions.
 
    The current prospectus for each  fund describes its investment  objective(s)
and  policies, and  shareholders should obtain  a copy and  examine it carefully
before investing. An exchange  will be treated for  federal income tax  purposes
the  same as a repurchase or redemption  of shares, on which the shareholder may
realize a capital gain or loss. However, the ability to deduct capital losses on
an exchange may be limited  in situations where there  is an exchange of  shares
within  ninety days  after the shares  are purchased. The  Exchange Privilege is
only available in states where an exchange may legally be made.
 
    For further  information  regarding  the  Exchange  Privilege,  shareholders
should  contact their DWR  or other selected  broker-dealer account executive or
the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    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 for the certificate and/or
written  request  in good  order. The  term  "good order"  means that  the share
certificate, if any, and request for redemption are properly signed, accompanied
by any  documentation  required  by  the  Transfer  Agent,  and  bear  signature
guarantees  when required by the Fund or the Transfer Agent. Such payment may be
postponed or the right of  redemption suspended at times  (a) when the New  York
Stock  Exchange is  closed for other  than customary weekends  and holidays, (b)
when trading on that Exchange is restricted,  (c) when an emergency exists as  a
result of which disposal by the Fund of securities owned by it is not reasonably
practicable or it is not reasonably practicable for the Fund fairly to determine
the  value of its net assets, or (d) during any other period when the Securities
and Exchange Commission by order so permits; provided that applicable rules  and
regulations of the Securities and Exchange Commission shall govern as to whether
the conditions prescribed in (b) or (c) exist. If the shares to be redeemed have
recently  been  purchased  by check  (including  a certified  or  bank cashier's
check), payment  of redemption  proceeds may  be delayed  for the  minimum  time
needed  to verify that the check used  for investment has been honored (not more
than fifteen days from the time of 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 accounts.
 
    REINSTATEMENT  PRIVILEGE.  As described 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 date of
redemption or repurchase, reinstate any portion  of all of the proceeds of  such
redemption  or repurchase in shares of the  Fund at the net asset value (without
sales charge) next determined after a reinstatement request, together with  such
proceeds, is received by the Transfer Agent.
 
    Exercise  of the reinstatement privilege will  not affect the federal income
tax treatment of any  gain or loss realized  upon the redemption or  repurchase,
except that if the redemption or repurchase resulted in a loss and reinstatement
is  made in shares of the Fund, some or all of the loss, depending on the amount
reinstated, will not be allowed as  a deduction for federal income tax  purposes
but  will  be applied  to  adjust the  cost basis  of  the shares  acquired upon
reinstatement.
 
                                       30
<PAGE>
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund will determine either to distribute
or to retain  all or part  of any net  long-term capital gains  in any year  for
reinvestment.  If any such gains are retained,  the Fund will pay federal income
tax thereon, and  will notify shareholders  that, following an  election by  the
Fund,  the shareholders will be required  to include such undistributed gains in
determining their taxable income and  may claim their share  of the tax paid  by
the Fund as a credit against their individual federal income tax.
 
    Because  the Fund intends to distribute all of its net investment income and
capital gains to shareholders and otherwise  continue to qualify as a  regulated
investment  company under Subchapter M  of the Internal Revenue  Code, it is not
expected that  the  Fund  will  be  required to  pay  any  federal  income  tax.
Shareholders  will  normally have  to pay  federal income  taxes, and  any state
income taxes, on  the dividends and  distributions they receive  from the  Fund.
Such  dividends and distributions, to the extent  that they are derived from net
investment income or short-term capital gains, are taxable to the shareholder as
ordinary income regardless of whether the shareholder receives such payments  in
additional  shares or in cash. Any dividends declared in the last quarter of any
year which are paid in the following  calendar year prior to February 1 will  be
deemed received by the shareholder in the prior year.
 
    Gains  or losses on  the sales of  securities by the  Fund generally will be
long-term capital gains or losses if the  securities have been held by the  Fund
for  more than twelve months. Gains or losses on the sale of securities held for
twelve months or less will be short-term capital gains or losses.
 
    Distributions of  net  long-term  capital  gains, if  any,  are  taxable  to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional  shares or in cash. Capital  gains distributions are not eligible for
the dividends received deduction.
 
    One of the  requirements for  the Fund to  remain qualified  as a  regulated
investment  company is that  less than 30%  of the gross  income be derived from
gains from the sale or other disposition of securities held for less than  three
months.  Accordingly, the Fund  may be restricted  in the writing  of options on
securities held for  less than  three months, in  the writing  of options  which
expire  in less  than three months,  and in effecting  closing transactions with
respect to call or put  options which have been  written or purchased less  than
three  months prior to such transactions. The Fund may also be restricted in its
ability to engage in transactions involving futures contracts.
 
    Under current federal law,  the Fund will receive  net investment income  in
the form of interest cash payments by virtue of holding fixed-income securities,
including   Treasury  bills,  notes   and  bonds,  and   will  recognize  income
attributable to it  from holding original  issue discount securities,  including
zero  coupon Treasury securities. Current federal tax law requires that a holder
(such as the Fund) of  an original issue discount  security accrue a portion  of
the discount at which the security was purchased as income each year even though
the  Fund receives no interest payment in  cash on the security during the year.
As an investment company,  the Fund must  pay out substantially  all of its  net
investment  income each year. Accordingly, the Fund, to the extent it invests in
original issue discount  securities, may  be required to  pay out  as an  income
distribution  each year an amount which is greater than the total amount of cash
receipts of interest the Fund actually received. Such distributions will be made
from the  available  cash  of  the  Fund or  by  the  liquidation  of  portfolio
securities  if necessary. If a distribution of cash necessitates the liquidation
of portfolio securities, the Investment Manager will select which securities  to
sell. The Fund may realize a gain or loss from such sales. In the event the Fund
realizes  net capital gains from such transactions, its shareholders may receive
a larger capital gain distribution,  if any, than they  would in the absence  of
such transactions.
 
    In  computing  net investment  income, the  Fund  will amortize  premiums or
accrue discounts on fixed-income securities in the portfolio. Realized gains and
losses on security transactions are determined on the identified cost method.
 
                                       31
<PAGE>
    Any dividend or capital  gains distribution received  by a shareholder  from
any  investment company will have the effect  of reducing the net asset value of
the shareholder's stock in that company by  the exact amount of the dividend  or
capital   gains  distribution.  Furthermore,  capital  gains  distributions  and
dividends are subject to  federal income taxes.  If the net  asset value of  the
shares  should be reduced below a shareholder's  cost as a result of the payment
of dividends  or the  distribution  of realized  long-term capital  gains,  such
payment  or  distribution  would  be  in  part  a  return  of  the shareholder's
investment to the  extent of such  reduction below the  shareholder's cost,  but
nonetheless  would be  fully taxable at  either ordinary or  capital gain rates.
Therefore, an investor should consider  the tax implications of purchasing  Fund
shares immediately prior to a dividend or distribution record date.
 
    The  straddle  rules of  Section  1092 of  the  Internal Revenue  Code where
applicable (i) require the Fund to defer losses incurred on certain transactions
involving securities, options and futures contracts, (ii) may affect the  Fund's
holding  period on the asset underlying an  option or futures contract and (iii)
in certain  instances, may  convert a  short-term capital  loss to  a  long-term
capital loss.
 
    Exchange-traded  futures contracts, listed options  on futures contracts and
listed options on U.S.  Government securities are  classified as "Section  1256"
contracts  under the Internal Revenue Code.  Section 1256 contracts are required
to be marked-to-market  at the end  of the  Fund's fiscal year,  for purpose  of
Federal  income tax calculations.  The character of gain  or loss resulting from
the  sale,   disposition,  closing   out,  expiration,   other  termination   or
mark-to-market  of  Section 1256  contracts  is generally  treated  as long-term
capital gain or loss to the extent of 60 percent thereof and short-term  capital
gain or loss to the extent of 40 percent thereof.
 
    Over-the-counter  options are not  classified as Section  1256 contracts and
are not subject to the mark-to-market  or 60 percent-40 percent taxation  rules.
When  put options purchased by the Fund are exercised, the gain or loss realized
on the sales of the underlying securities may be either short-term or long-term,
generally depending upon the  holding period of  the securities. In  determining
the  amount of gain or loss, the sales  proceeds are reduced by the premium paid
for  over-the-counter   puts  or   increased  by   the  premium   received   for
over-the-counter calls.
 
    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, any  portion
taxable  as long-term  capital gains  and any  portion treated  as a non-taxable
return of capital. Any such return of capital will reduce the shareholders'  tax
basis  in  their  shares.  To  avoid  being  subject  to  a  31%  federal backup
withholding tax  on  taxable  dividends, capital  gains  distributions  and  the
proceeds  of redemptions and  repurchases, shareholders' taxpayer identification
numbers must be furnished and certified as to their accuracy.
 
    Shareholders should  consult  their  attorneys  or  tax  advisers  regarding
specific questions as to state or local taxes and as to the applicability of the
foregoing to their current federal tax situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    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 maximum offering price  per share on the last
day of the period  multiplied by the average  number of Fund shares  outstanding
during the period that were entitled to dividends. This amount is added to 1 and
raised  to  the  sixth power.  1  is then  subtracted  from the  result  and the
difference is multiplied by 2 to arrive at the annualized yield. For the  30-day
period  ended October  31, 1996, the  Fund's yield, calculated  pursuant to this
formula, was 5.12%.
 
    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
 
                                       32
<PAGE>
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.  The
average  annual total returns of the Fund for the one and five year period ended
October 31,  1996  and  for  the  period from  July  1,  1991  (commencement  of
operations) through October 31, 1996 were 1.92%, 3.85% and 4.82%, respectively.
 
    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time by means of aggregate, average, year-by-year or  other
types  of total  return figures.  Such calculation  may or  may not  reflect the
imposition of the maximum front end sales charge. In addition, the Fund may also
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  this calculation,  the
average  annual  total  return of  the  Fund,  excluding the  imposition  of the
front-end sales charge, for the one and five year period ended October 31,  1996
and  for the period from July 1, 1991 through October 31, 1996 were 5.07%, 4.48%
and 5.42%, respectively.
 
    In addition, the Fund may compute  its aggregate total return for  specified
periods  by determining the  aggregate percentage rate which  will result in the
ending value of a  hypothetical $1,000 investment made  at the beginning of  the
period.  For the purpose of  this calculation, it is  assumed that all dividends
and distributions  are reinvested.  The formula  for computing  aggregate  total
return  involves  a percentage  obtained  by dividing  the  ending value  by the
initial $1,000  investment and  subtracting  1 from  the  result. Based  on  the
foregoing  calculation, the Fund's total return for the one and five year period
ended October 31, 1996 and for the period from July 1, 1991 through October  31,
1996 were 5.07%, 24.52% and 32.51%, respectively.
 
    The  Fund  may  also advertise  the  growth of  hypothetical  investments of
$10,000, $50,000 and $100,000 in  shares of the Fund by  adding 1 to the  Fund's
aggregate  total return  to date and  multiplying by $9,700,  $48,500 or $97,500
($10,000, $50,000  or $100,000  adjusted for  a 3%,  3% and  2.5% sales  charge,
respectively). Investments of $10,000 and $50,000 adjusted for a 3% sales charge
in  the Fund at inception  would have grown to  $12,853 and $64,267 respectively
and an investment of $100,000 adjusted for a 2.5% sales charge, in the Fund from
inception would have grown to $129,197 at October 31, 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.  All of the Trustees except for  Messrs. Bozic, Purcell and Schroeder have
been elected by the shareholders of the Fund, most recently at a special meeting
of shareholders held on January 12,  1993. Messrs. Bozic, Purcell and  Schroeder
were  elected by the other  Trustees of the Fund on  April 8, 1994. The Trustees
themselves have the power  to alter the  number and the terms  of office of  the
Trustees,  and they may at any time lengthen 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
 
                                       33
<PAGE>
also  have the  right under  certain circumstances  to remove  the Trustees. The
voting rights of shareholders are not  cumulative, so that holders of more  than
50  percent of the shares  voting can, if they  choose, elect all Trustees being
selected, while the holders of the remaining shares would be unable to elect any
Trustees.
 
    The 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.
 
    The  Declaration of Trust permits the  Trustees to authorize the creation of
additional series  of  shares  (the  proceeds of  which  would  be  invested  in
separate,  independently managed  portfolios) and  additional classes  of shares
within any  series (which  would be  used  to distinguish  among the  rights  of
different categories of shareholders, as might be required by future regulations
or  other unforeseen circumstances). The  Trustees have not presently authorized
any such additional series or classes of shares.
 
    The Declaration of Trust further provides that no Trustee, officer, employee
or agent of  the Fund is  liable to  the Fund or  to a shareholder,  nor is  any
Trustee,  officer, employee or  agent liable to any  third persons in connection
with the affairs of the Fund, except as such liability may arise from his/her or
its own bad faith, willful misfeasance, gross negligence, or reckless  disregard
of  his/her or its  duties. It also  provides that all  third persons shall look
solely to the Fund's property for  satisfaction of claims arising in  connection
with  the affairs of  the Fund. With  the exceptions stated,  the Declaration of
Trust provides that  a Trustee,  officer, employee or  agent is  entitled to  be
indemnified against all liability in connection with the affairs of the Fund.
 
    The  Fund is authorized to issue an unlimited number of shares of beneficial
interest. The Fund shall be of  unlimited duration subject to the provisions  in
the Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER PREMIER INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996
 
1. ORGANIZATION AND ACCOUNTING POLICIES
Dean Witter Premier Income Trust (the "Fund") is registered under the Investment
Company Act of 1940, as amended (the "Act"), as a diversified, open-end
management investment company. The Fund's investment objective is to earn a high
level of current income consistent with low volatility of principal. The Fund
was organized as a Massachusetts business trust on March 27, 1991 and commenced
operations on July 1, 1991.
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) 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, including circumstances under which it is
determined by the Investment Manager or Sub-Advisor that sale or bid prices are
not reflective of a security's market value, portfolio securities are valued at
their fair value as determined in good faith under procedures established by and
under the general supervision of the Trustees (valuation of debt securities for
which market quotations are not readily available may be based upon current
market prices of securities which are comparable in coupon, rating and maturity
or an appropriate matrix utilizing similar factors); (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
evaluations by its staff, including review of broker-dealer market price
quotations, if available, in determining what it believes is the fair valuation
of the portfolio securities valued by such pricing service; and (4) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.
B. ACCOUNTING FOR INVESTMENTS --  Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
The Fund amortizes premiums and accretes discounts based on the respective life
of the securities. Interest income is accrued daily.
 
                                       42
<PAGE>
DEAN WITTER PREMIER INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996, CONTINUED
 
C. DOLLAR ROLLS --  The Fund may enter into dollar rolls in which the Fund sells
securities for delivery and simultaneously contracts to repurchase substantially
similar securities at the current sales price on a specified future date. The
difference between the current sales price and the lower forward price for the
future purchase (often referred to as the "drop") is amortized over the life of
the dollar roll.
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 ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
F. ORGANIZATIONAL EXPENSES --  Dean Witter InterCapital Inc. (the "Investment
Manager") paid the organizational expenses of the Fund in the amount of
approximately $150,000 which have been reimbursed for the full amount thereof.
Such expenses were fully amortized as of June 30, 1996.
2. INVESTMENT MANAGEMENT AND SUB-ADVISORY AGREEMENTS
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
annual rate of 0.50% 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
 
                                       43

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.
Under a Sub-Advisory Agreement between BlackRock Financial Management Inc. (the
"Sub-Advisor") and the Investment Manager, the Sub-Advisor provides the Fund
with investment advice and portfolio management relating to the Fund's
investment in securities, subject to the overall supervision of the Investment
Manager. As compensation for its services provided pursuant to the Sub-Advisory
Agreement, the Investment Manager pays the Sub-Advisor monthly compensation
equal to 40% of its monthly compensation.
3. PLAN OF DISTRIBUTION
Dean Witter Distributors Inc. (the "Distributor"), an affiliate of the
Investment Manager, is the distributor of the Fund's shares and, in accordance
with a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act,
finances certain expenses in connection with the distribution of shares of the
Fund.
Under the Plan, the Distributor bears the expense of all promotional and
distribution related activities on behalf of the Fund, except for expenses that
the Trustees determine to reimburse, as described below. The following
activities and services may be provided by the Distributor under the Plan: (1)
compensation to, and expenses of, account executives of Dean Witter Reynolds
Inc., an affiliate of the Investment Manager and Distributor, and employees and
other selected broker-dealers; (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.
The Fund is authorized to reimburse the Distributor for specific expenses the
Distributor incurs or plans to incur in promoting the distribution of the Fund's
shares. The amount of each monthly reimbursement payment may in no event exceed
an amount equal to a payment at the annual rate of 0.20% of the Fund's average
daily net assets during the month. For the year ended October 31, 1996, the
distribution fee was accrued at the annual rate of 0.18%.

they are deducted from the proceeds of sales of beneficial interest.
4. 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 October 31,
1996 were $91,759,957 and $105,398,044, respectively. Included in the

Dean Witter Trust Company, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent. At October 31, 1996, the Fund had
transfer agent fees and expenses payable of approximately $3,249.
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended October 31, 1996 included
in Trustees' fees and expenses in the Statement of Operations amounted to
$5,775. At October 31, 1996, the Fund had an accrued pension liability of
$36,695 which is included in accrued expenses in the Statement of Assets and
Liabilities.

DEAN WITTER PREMIER INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996, CONTINUED
 
6. FEDERAL INCOME TAX STATUS
During the year ended October 31, 1996, the Fund utilized approximately $36,000
of its net capital loss carryover. At October 31, 1996, the Fund had a net
capital loss carryover of approximately $6,144,000 of which $4,973,000 will be
available through October 31, 2001 and $1,171,000 will be available through
October 31, 2002 to offset future capital gains to the extent provided by
regulations.
To reflect reclassifications arising from permanent book/tax differences for the
year ended October 31, 1996 accumulated net realized loss was charged $157,
paid-in-capital was charged $50,073 and distributions in excess of net
investment income was credited $50,230.
7. REVERSE REPURCHASE AND DOLLAR ROLL AGREEMENTS
Reverse repurchase and dollar roll agreements involve the risk that the market
value of the securities the Fund is obligated to repurchase under the agreement
may decline below the repurchase price. In the event the buyer of securities
under a reverse repurchase agreement or dollar roll files for bankruptcy or
becomes insolvent, the Fund's use of proceeds may be restricted pending a
determination by the other party, its trustee or receiver, whether to enforce
the Fund's obligation to repurchase the securities.
Reverse repurchase agreements are collateralized by Fund securities with a
market value in excess of the Fund's obligation under the contract. At October
31, 1996, the reverse repurchase agreements outstanding were $8,256,000 with a
weighted average interest rate of 5.29% maturing within 6 days, for which
securities valued at $8,294,786 including accrued interest were pledged as
collateral. The maximum and average daily amounts outstanding during the year
were $12,305,942 and $7,307,865, respectively. The weighted average interest
rate during the year was 5.37%.

DEAN WITTER PREMIER INCOME TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER PREMIER INCOME TRUST
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations, of cash
flows and of changes in net assets and the financial highlights present fairly,
in all material respects, the financial position of Dean Witter Premier Income
Trust (the "Fund") at October 31, 1996, the results of its operations and its
cash flows 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 five years in the period then ended and for the period July 1, 1991
(commencement of operations) through October 31, 1991, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at October 31, 1996 by
correspondence with the custodian and a broker, provide a reasonable basis for
the opinion expressed above.

Shares of Beneficial Interest


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

                                        2
<PAGE>

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

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

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

the business of the Trust may require. 

                                 ARTICLE III 

                            SHAREHOLDERS' MEETINGS 

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

   SECTION 3.2. MEETINGS. Meetings of Shareholders of the Trust shall be held 
whenever called by the Trustees or the President of the Trust and whenever 
election of a Trustee or Trustees by Shareholders is required by the 
provisions of Section 16(a) of the 1940 Act, for that purpose. Meetings of 
Shareholders shall also be called by the Secretary upon the written request 
of the holders of Shares entitled to vote not less than twenty-five percent 
(25%) of all the votes entitled to be cast at such meeting, except to the 
extent otherwise required by Section 16(c) of the 1940 Act, as made 
applicable to the Trust by the provisions of Section 2.3 of the Declaration. 
Such request shall state the purpose or purposes of such meeting and the 
matters proposed to be acted on thereat. Except to the extent otherwise 
required by Section 16(c) of the 1940 Act, as made applicable to the Trust by 
the provisions of Section 2.3 of the Declaration, the Secretary shall inform 
such Shareholders of the reasonable estimated cost of preparing and mailing 
such notice of the meeting, and upon payment to the Trust of such costs, the 
Secretary shall give notice stating the purpose or purposes of the meeting to 
all entitled to vote at such meeting. No meeting need be called upon the 
request of the holders of Shares entitled to cast less than a majority of all 
votes entitled to be cast at such meeting, to consider any matter which is 
substantially the same as a matter voted upon at any meeting of Shareholders 
held during the preceding twelve months. 

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

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

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

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

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

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

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

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

                                  ARTICLE IV 

                                   TRUSTEES 

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

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

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

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

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

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

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

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

                                       3           
<PAGE>

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

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

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

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

       (2) The determination shall be made: 

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

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

     (iii) By the Shareholders. 

     (3) Notwithstanding any provision of this Section 4.8, no person shall 
    be entitled to indemnification for any liability, whether or not there is 
    an adjudication of liability, arising by reason of willful misfeasance, 
    bad faith, gross negligence, or reckless disregard of duties as described 
    in Section 17(h) and (i) of the Investment Company Act of 1940 
    ("disabling conduct"). A person shall be deemed not liable by reason of 
    disabling conduct if, either: 

       (i) a final decision on the merits is made by a court or other body 
    before whom the proceeding was brought that the person to be indemnified 
    ("indemnitee") was not liable by reason of disabling conduct; or 

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


                                       4           
<PAGE>

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

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

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

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

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

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

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

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

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

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

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

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

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

                                  ARTICLE V 

                                  COMMITTEES 

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

                                       5           

<PAGE>

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

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

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

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

                                  ARTICLE VI 

                                   OFFICERS 

   SECTION 6.1. EXECUTIVE OFFICERS. The executive officers of the Trust shall 
be a Chairman, a President, one or more Vice Presidents, a Secretary and a 
Treasurer. The Chairman shall be selected from among the Trustees but none of 
the other executive officers need be a Trustee. Two or more offices, except 
those of President and any Vice President, may be held by the same person, 
but no officer shall execute, acknowledge or verify any instrument in more 
than one capacity. The executive officers of the Trust shall be elected

                         DIVIDENDS AND DISTRIBUTIONS 

   Subject to any applicable provisions of law and the Declaration, dividends 
and distributions upon the Shares may be declared at such intervals as the

                                       7           

<PAGE>

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

                                 ARTICLE VIII 

                            CERTIFICATES OF SHARES 

   SECTION 8.1. CERTIFICATES OF SHARES. Certificates for Shares of each 
series or class of Shares shall be in such form and of such design as the 
Trustees shall approve, subject to the right of the Trustees to change such 
form and design at any time or from time to time, and shall be entered in the 
records of the Trust as they are issued. Each such certificate shall bear a 
distinguishing number; shall exhibit the holder's name and certify the number 
of full Shares owned by such holder; shall be signed by or in the name of the 
Trust by the President, or a Vice President, and countersigned by the 
Secretary or an Assistant Secretary or the Treasurer and an Assistant 
Treasurer of the Trust; shall be sealed with the seal; and shall contain such 
recitals as may be required by law. Where any certificate is signed by a 
Transfer Agent or by a Registrar, the signature of such officers and the seal 
may be facsimile, printed or engraved. The Trust may, at its option, 
determine not to issue a certificate or certificates to evidence Shares owned 
of record by any Shareholder. 

   In case any officer or officers who shall have signed, or whose facsimile 
signature or signatures shall appear on, any such certificate or certificates 
shall cease to be such officer or officers of the Trust, whether because of 
death, resignation or otherwise, before such certificate or certificates 
shall have been delivered by the Trust, such certificate or certificates 
shall, nevertheless, be adopted by the Trust and be issued and delivered as 
though the person or persons who signed such certificate or certificates or 
whose facsimile signature or signatures shall appear therein had not ceased 
to be such officer or officers of the Trust. 

   No certificate shall be issued for any share until such share is fully 
paid. 

   SECTION 8.2. LOST, STOLEN, DESTROYED AND MUTILATED CERTIFICATES. The 
Trustees may direct a new certificate or certificates to be issued in place 
of any certificate or certificates theretofore issued by the Trust alleged to 
have been lost, stolen or destroyed, upon satisfactory proof of such loss, 
theft, or destruction; and the Trustees may, in their discretion, require the 
owner of the lost, stolen or destroyed certificate, or his legal 
representative, to give to the Trust and to such Registrar, Transfer Agent 
and/or Transfer Clerk as may be authorized or required to countersign such 
new certificate or certificates, a bond in such sum and of such type as they 
may direct, and with such surety or sureties, as they may direct, as 
indemnity against any claim that may be against them or any of them on 
account of or in connection with the alleged loss, theft or destruction of 
any such certificate. 

                                  ARTICLE IX 

                                  CUSTODIAN 

   SECTION 9.1. APPOINTMENT AND DUTIES. The Trust shall at times employ a 
bank or trust company having capital, surplus and undivided profits of at 
least five million dollars ($5,000,000) as custodian with authority as its 
agent, but subject to such restrictions, limitations and other requirements, 
if any, as may be contained in these By-Laws and the 1940 Act: 

     (1) to receive and hold the securities owned by the Trust and deliver 
    the same upon written or electronically transmitted order; 

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

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


                                       8           

<PAGE>

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

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

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

                                  ARTICLE X 

                               WAIVER OF NOTICE 

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

                                  ARTICLE XI 

                                MISCELLANEOUS

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

   SECTION 11.2. RECORD DATE. The Trustees may fix in advance a date as the 
record date for the purpose of determining Shareholders entitled to notice 
of, or to vote at, any meeting of Shareholders, or Shareholders entitled to 
receive payment of any dividend or the allotment of any rights, or in order 
to make a determination of Shareholders for any other proper purpose. Such 
date, in any case, shall be not more than ninety (90) days, and in case of a 
meeting of Shareholders not less than ten (10) days, prior to the date on 
which particular action requiring such determination of Shareholders is to be 
taken. In lieu of fixing a record date the Trustees may provide that the 
transfer books shall be closed for a stated period but not to exceed, in any 
case, twenty (20) days. If the transfer books are closed for the purpose of 
determining Shareholders entitled to notice of a vote at a meeting of 
Shareholders, such books shall be closed for at least ten (10) days 
immediately preceding such meeting. 

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

   SECTION 11.4. FISCAL YEAR. The fiscal year of the Trust shall end on such 
date as the Trustees may by resolution specify, and the Trustees may by 
resolution change such date for future fiscal years at any time and from time 
to time. 

                                       9

   SECTION 11.5. ORDERS FOR PAYMENT OF MONEY. All orders or instructions for 
the payment of money of the Trust, and all notes or other evidences of 
indebtedness issued in the name of the Trust, shall be signed by such officer 
or officers or such other person or persons as the Trustees may from time to 
time designate, or as may be specified in or pursuant to the agreement 
between the Trust and the bank or trust company appointed as Custodian of the 
securities and funds of the Trust. 

                                 ARTICLE XII 

                     COMPLIANCE WITH FEDERAL REGULATIONS 

   The Trustees are hereby empowered to take such action as they may deem to 
be necessary, desirable or appropriate so that the Trust is or shall be in 
compliance with any federal or state statute, rule or regulation with which 
compliance by the Trust is required. 

                                 ARTICLE XIII 

                                  AMENDMENTS 

   These By-Laws may be amended, altered, or repealed, or new By-Laws may be 
adopted, (a) by a Majority Shareholder Vote, or (b) by the Trustees; 
provided, however, that no By-Law may be amended, adopted or repealed by the 
Trustees if such amendment, adoption or repeal requires, pursuant to law, the 
Declaration, or these By-Laws, a vote of the Shareholders. The Trustees shall 
in no event adopt By-Laws which are in conflict with the Declaration, and any 
apparent inconsistency shall be construed in favor of the related provisions 
in the Declaration. 

                                 ARTICLE XIV 

                             DECLARATION OF TRUST 

   The Declaration of Trust establishing Dean Witter Premier Income Trust, 
dated March 26, 1991, a copy of which is on file in the office of the 
Secretary of the Commonwealth of Massachusetts, provides that the name Dean 
Witter Premier Income Trust refers to the Trustees under the Declaration 
collectively as Trustees, but not as individuals or personally; and no 
Trustee, Shareholder, officer, employee or agent of Dean Witter Premier 
Income Trust shall be held to any personal liability, nor shall resort be had 
to their private property for the satisfaction of any obligation or claim or 
otherwise, in connection with the affairs of said Dean Witter Premier Income 
Trust, but the Trust Estate only shall be liable.

                         AMENDMENT TO CUSTODY AGREEMENT

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

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

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

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

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

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