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
August 5, 1988.
 
THE INVESTMENT MANAGER
 
    Dean Witter InterCapital Inc. (the "Investment Manager" or "InterCapital"),

subsidiary of Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD"), 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

"InterCapital" and "Investment Manager" refer to DWR's InterCapital Division
prior to the internal reorganization and to Dean Witter InterCapital Inc.
thereafter.) The daily management of the Fund and research relating to the
Fund's portfolio are conducted by or under the direction of officers of the Fund
and of the Investment Manager, subject to review by the Fund's Board of
Trustees. Information as to these Trustees and officers is contained under the

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 Total Return Trust, TCW/DW Mid-Cap Equity

Emerging Markets Opportunities Trust, TCW/DW Term Trust 2000, TCW/DW Term Trust

as: (i) administrator of The BlackRock Strategic Term Trust Inc., a closed-end
investment company; and (ii) sub-administrator of MassMutual Participation
Investors and Templeton Global Governments Income Trust, closed-end investment
companies.
 
    Pursuant to an Investment Management Agreement (the "Agreement") with the
Investment Manager, the Fund has retained the Investment Manager to manage the
investment of the Fund's assets, including the placing of orders for the
purchase and sale of portfolio securities. The Investment Manager obtains and
evaluates such information and advice relating to the economy, securities
markets, and specific securities as it considers necessary or useful to
continuously manage the assets of the Fund in a manner consistent with its
investment objective. Under the terms of the Agreement, in addition to managing
the Fund's investments, the Investment Manager maintains certain of the Fund's
books and records and furnishes, at its own expense, such office space,
facilities, equipment, clerical help and bookkeeping and legal services as the
Fund may reasonably require in the conduct of its business, including the
preparation of prospectuses, statements of additional information, proxy
statements and reports required to be filed with federal and state securities
commissions (except insofar as the participation or assistance of independent
accountants and attorneys is, in the opinion of the Investment Manager,
necessary or desirable). In addition, the Investment Manager pays the salaries
of all personnel, including officers of the Fund, who are employees of the
Investment Manager. The Investment Manager also bears the cost of telephone
service, heat, light, power and other utilities provided to the Fund.
 
    Effective December 31, 1993, pursuant to a Services Agreement between
InterCapital and DWSC, DWSC began to provide the administrative services to the
Fund which were previously performed directly by InterCapital. On April 17,
1995, DWSC was reorganized in the State of Delaware, necessitating the entry
into a new Services Agreement by InterCapital and DWSC on such date. The
foregoing internal reorganizations did not result in any change in the nature or
scope of the administrative services being provided to the Fund or any of the
fees being paid by the Fund for the overall services being performed under the
terms of the existing Agreement.
 
    Expenses not expressly assumed by the Investment Manager under the Agreement
or by the Distributor of the Fund's shares, Dean Witter Distributors Inc.
("Distributors" or the "Distributor") (see "The Distributor"), will be paid by
the Fund. These expenses will be allocated among the four classes of shares of
the Fund (each, a "Class") pro rata based on the net assets of the Fund
attributable to each Class, except as described below. Such expenses include,
but are not limited to: expenses of the Plan of Distribution pursuant to Rule
12b-1 (the "12b-1 fee") (see "The Distributor"); charges and expenses of any
registrar; custodian, stock transfer and dividend disbursing agent; brokerage
commissions; taxes; engraving and printing of share certificates; registration
costs of the Fund and its shares under federal and state securities laws; the
cost and expense of printing, including typesetting, and distributing
Prospectuses and Statements of Additional Information of the Fund and
supplements thereto to the Fund's shareholders; all expenses of shareholders'
and Trustees' meetings and of preparing, printing and mailing of proxy
statements and reports to shareholders; fees and travel expenses of Trustees or
members of any advisory board or committee who are not employees of the
Investment Manager or any corporate affiliate of the Investment Manager; all
expenses incident to any dividend, withdrawal or redemption options; charges and
expenses of any outside service used for pricing of the Fund's shares;
 
                                       4
<PAGE>
fees and expenses of legal counsel, including counsel to the Trustees who are
not interested persons of the Fund or of the Investment Manager (not including
compensation or expenses of attorneys who are employees of the Investment
Manager) and independent accountants; membership dues of industry associations;
interest on Fund borrowings; postage; insurance premiums on property or
personnel (including officers and Trustees) of the Fund which inure to its
benefit; extraordinary expenses (including, but not limited to, legal claims and
liabilities and litigation costs and any indemnification relating thereto); and
all other costs of the Fund's operation. The 12b-1 fees relating to a particular
Class will be allocated directly to that Class. In addition, other expenses
associated with a particular Class (except advisory or custodial fees) may be
allocated directly to that Class, provided that such expenses are reasonably
identified as specifically attributable to that Class and the direct allocation
to that Class is approved by the Trustees.
 
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying the
following annual rates to the Fund's daily net assets: 0.60% of the portion of
the daily net assets not exceeding $500 million; 0.55% of the next $500 million;
0.50% of the next $500 million; and 0.475% of the portion of the daily net
assets exceeding $1.5 billion. The management fee is allocated among the Classes
pro rata based on the net assets of the Fund attributable to each Class. For the
fiscal years ended July 31, 1995, 1996 and 1997, the Fund accrued to the
Investment Manager total compensation of $4,679,443, $6,414,184 and $7,751,652,
respectively.
 
    The Agreement provides that in the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of its obligations thereunder, the
Investment Manager is not liable to the Fund or any of its investors for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors. The Agreement in no way restricts the Investment Manager from
acting as investment manager or adviser to others.
 
    The Agreement was initially approved by the Board of Trustees on February
21, 1997 and by the shareholders of the Fund at a Special Meeting of
Shareholders held on May 21, 1997. The Agreement is substantially identical to a
prior investment management agreement which was initially approved by the Board
of Trustees on October 30, 1992 and by the shareholders of the Fund at a Special
Meeting of Shareholders held on January 12, 1993, as such agreement had been
amended by the Trustees at their meetings held on April 28, 1993 and April 17,
1996, to lower the management fees charged on the Fund's daily net assets in
excess of $1 billion and $1.5 billion. The Agreement took effect on May 31, 1997
upon the consummation of the merger of Dean Witter, Discover & Co. with Morgan
Stanley Group Inc. The Agreement may be terminated at any time, without penalty,
on thirty days' notice by the Trustees of the Fund, by the holders of a
majority, as defined in the Act, of the outstanding shares of the Fund, or by
the Investment Manager. The Agreement will automatically terminate in the event
of its assignment (as defined in the Act).
 
    Under its terms, the Agreement had an initial term ending April 30, 1999 and
will remain in effect from year to year thereafter, provided continuance of the
Agreement is approved at least annually by the vote of the holders of a
majority, as defined in the Act, of the outstanding shares of the Fund, or by
the Trustees of the Fund; provided that in either event such continuance is
approved annually by the vote of a majority of the Trustees of the Fund who are
not parties to the Agreement or "interested persons" (as defined in the Act) of
any such party (the "Independent Trustees"), which vote must be cast in person
at a meeting called for the purpose of voting on such approval.

    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR. The Fund has agreed that DWR or its parent company may use, or at any time
permit others to use, the name "Dean Witter." The Fund has also agreed that in
the event the Agreement is terminated, or if the affiliation between

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
 
    The Board of Trustees currently consists of nine (9) trustees. These same
individuals also serve as directors or trustees for all of the Dean Witter
Funds, and are referred to in this section as Trustees. As of the date of this
Statement of Additional Information, there are a total of 84 Dean Witter Funds,
comprised of 127 portfolios. As of August 31, 1997, the Dean Witter Funds had
total net assets of approximately $90.6 billion and more than six million
shareholders.
 
    Seven Trustees (77% of the total number) have no affiliation or business
connection with InterCapital or any of its affiliated persons and do not own any
stock or other securities issued by InterCapital's parent company, MSDWD. These
are the "disinterested" or "independent" Trustees. The other two Trustees (the
"management Trustees") are affiliated with InterCapital. Four 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'
 
                                       8
<PAGE>
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, 1996,
the three Committees held a combined total of sixteen 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 Trustees and the Audit
Committee maintains an office at the Funds' headquarters in New York. He is
responsible for keeping abreast of regulatory and industry developments and the
Funds' operations and management. He screens and/or prepares written materials
and identifies critical issues for the Independent Trustees to consider,
develops agendas for Committee meetings, determines the type and amount of
information that the Committees will need to form a judgment on various issues,
and arranges to have that information furnished to Committee members. He also
arranges for the services of independent experts and consults with them in
advance of meetings to help refine reports and to focus on critical issues.
Members of the Committees believe that the person who serves as Chairman of both
Committees and guides their efforts is pivotal to the effective functioning of
the Committees.
 
    The Chairman of the Committees also maintains continuous contact with the
Funds' management, with independent counsel to the Independent Trustees and with
the Funds' independent auditors. He arranges for a series of special meetings
involving the annual review of investment advisory, management and other
operating contracts of the Funds and, on behalf of the Committees, conducts
negotiations with the Investment Manager and other service providers. In effect,
the Chairman of the Committees serves as a combination of chief executive and
support staff of the Independent Trustees.
 
    The Chairman of the Committee of the Independent Trustees and the Audit
Committee is not employed by any other organization and devotes his time
primarily to the services he performs as Committee Chairman and Independent
Trustee of the Dean Witter Funds and as an Independent Trustee
 
                                       9
<PAGE>
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). If a Board meeting
and a Committee meeting, or more than one Committee meeting, take place on a
single day, the Trustees are paid a single meeting fee by the Fund. 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 July 31, 1997.

    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.(1) "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 July 31, 1997
and by the 57 Dean Witter Funds (including the Fund) as of December 31, 1996,
and the estimated retirement benefits for the Fund's Independent Trustees, to
commence upon their retirement, from the Fund as of July 31, 1997 and from the
57 Dean Witter Funds as of December 31, 1996.

(1) 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

<PAGE>
    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.
 
(2) Based on current levels of compensation. Amount of annual benefits also
    varies depending on the Trustee's elections described in Footnote (1) above.
 
(3) These numbers reflect the effect of the combination of the net assets of
    Dean Witter Managed Assets Trust with those of the Fund on December 22, 1995
    pursuant to an Agreement and Plan of Reorganization.
 
    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 stated in the Prospectus, the Fund may
invest in short-term to intermediate (one to five year maturities) and
intermediate to long term (greater than five year maturities) fixed-income
securities which are issued or guaranteed, as to principal and interest, by the
United States or its agencies and instrumentalities.
 
    Such U.S. Government securities include:
 
        (1) U.S. Treasury bills (maturities of one year or less), U.S. Treasury
    notes (maturities of one to ten years) and U.S. Treasury bonds (generally
    maturities of greater than ten years), all of which are direct obligations
    of the U.S. Government and, as such, are backed by the "full faith and
    credit" of the United States.
 
        (2) Securities issued by agencies and instrumentalities of the U.S.
    Government which are backed by the full faith and credit of the United
    States. Among the agencies and instrumentalities issuing such obligations
    are the Federal Housing Administration, the Government National Mortgage
    Association ("GNMA"), the Department of Housing and Urban Development, the
    Export-Import Bank, the Farmers Home Administration, the General Services
    Administration, the Maritime Administration and the Small Business
    Administration. The maturities of such obligations range from three months
    to thirty years.
 
        (3) Securities issued by agencies and instrumentalities which are not
    backed by the full faith and credit of the United States, but whose issuing
    agency or instrumentality has the right to borrow, to meet its obligations,
    from an existing line of credit with the U.S. Treasury. Among the agencies
    and instrumentalities issuing such obligations are the Tennessee Valley
    Authority, the Federal National Mortgage Association ("FNMA"), the Federal
    Home Loan Mortgage Corporation ("FHLMC") and the U.S. Postal Service.
 
        (4) Securities issued by agencies and instrumentalities which are not
    backed by the full faith and credit of the United States, but which are
    backed by the credit of the issuing agency or instrumentality. Among the
    agencies and instrumentalities issuing such obligations are the Federal Farm
    Credit System and the Federal Home Loan Banks.
 
    ZERO COUPON SECURITIES.  A portion of the U.S. Government securities
purchased by the Fund may be zero coupon securities. Such securities are
purchased at a discount from their face amount, giving the purchaser the right
to receive their full value at maturity. The interest earned on such securities
is, implicitly, automatically compounded and paid out at maturity. While such
compounding at a constant rate eliminates the risk of receiving lower yields
upon reinvestment of interest if prevailing interest rates decline, the owner of
a zero coupon security will be unable to participate in higher yields upon
reinvest-
 
                                       12
<PAGE>
ment of interest received if prevailing interest rates rise. For this reason,
zero coupon securities are subject to substantially greater price fluctuations
during periods of changing prevailing interest rates than are comparable
securities which pay interest currently.
 
    MONEY MARKET INSTRUMENTS.  As stated in the Prospectus, the money market
instruments which the Fund may purchase include U.S. Government securities, bank
obligations, Eurodollar certificates of deposit, obligations of savings
institutions, fully insured certificates of deposit and commercial paper. Such
securities are limited to:
 
        U.S. GOVERNMENT SECURITIES.  Obligations issued or guaranteed as to
    principal and interest by the United States or its agencies (such as the
    Export-Import Bank of the United States, Federal Housing Administration and
    Government National Mortgage Association) or its instrumentalities (such as
    the Federal Home Loan Bank), including Treasury bills, notes and bonds;
 
        BANK OBLIGATIONS.  Obligations (including certificates of deposit and
    bankers' acceptances) of banks subject to regulation by the U.S. Government
    and having total assets of $1 billion or more, and instruments secured by
    such obligations, not including obligations of foreign branches of domestic
    banks except to the extent below;
 
        EURODOLLAR CERTIFICATES OF DEPOSIT.  Eurodollar certificates of deposit
    issued by foreign branches of domestic banks having total assets of $1
    billion or more;
 
        OBLIGATIONS OF SAVINGS INSTITUTIONS.  Certificates of deposit of savings
    banks and savings and loan associations, having total assets of $1 billion
    or more;
 
        FULLY INSURED CERTIFICATES OF DEPOSIT.  Certificates of deposit of banks
    and savings institutions, having total assets of less than $1 billion, if
    the principal amount of the obligation is insured by the Federal Deposit
    Insurance Corporation, limited to $100,000 principal amount per certificate
    and to 10% or less of the Fund's total assets in all such obligations and in
    all illiquid assets, in the aggregate;
 
        COMMERCIAL PAPER.  Commercial paper rated within the two highest grades
    by Standard & Poor's Corporation ("S&P") or the highest grade by Moody's
    Investors Service, Inc. ("Moody's") or, if not rated, issued by a company
    having an outstanding debt issue rated at least AA by S&P or Aa by Moody's.
 
    LENDING OF PORTFOLIO SECURITIES.  Consistent with applicable regulatory
requirements, the Fund may lend its portfolio securities to brokers, dealers and
other financial institutions, provided that such loans are callable at any time
by the Fund (subject to notice provisions described below), and are at all times
secured by cash or cash equivalents, which are maintained in a segregated
account pursuant to applicable regulations and that are equal to at least the
market value, determined daily, of the loaned securities. The advantage of such
loans is that the Fund continues to receive the income on the loaned securities
while at the same time earning interest on the cash amounts deposited as
collateral, which will be invested in short-term obligations. The Fund will not
lend its portfolio securities if such loans are not permitted by the laws or
regulations of any state in which its shares are qualified for sale and will not
lend more than 25% of the value of its total assets. A loan may be terminated by
the borrower on one business days' notice, or by the Fund on two business days'
notice. If the borrower fails to deliver the loaned securities within two days
after receipt of notice, the Fund could use the collateral to replace the
securities while holding the borrower liable for any excess of replacement cost
over collateral. As with any extensions of credit, there are risks of delay in
recovery and in some cases even loss of rights in the collateral should the
borrower of the securities fail financially. However, these loans of portfolio
securities will only be made to firms deemed by the Fund's management to be
creditworthy and when the income which can be earned from such loans justifies
the attendant risks. Upon termination of the loan, the borrower is required to
return the securities to the Fund. Any gain or loss in the market price during
the
 
                                       13
<PAGE>
loan period would inure to the Fund. The creditworthiness of firms to which the
Fund lends its portfolio securities will be monitored on an ongoing basis by the
Investment Manager pursuant to procedures adopted and reviewed, on an ongoing
basis, by the Board of Trustees of the Fund.
 
    When voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loaned securities, to
be delivered within one day after notice, to permit the exercise of such rights
if the matters involved would have a material effect on the Fund's investment in
such loaned securities. The Fund will pay reasonable finder's, administrative
and custodial fees in connection with a loan of its securities. The Fund did not
lend any of its portfolio securities during the fiscal year ended July 31, 1997.
 
    REPURCHASE AGREEMENTS.  When cash may be available for only a few days, it
may be invested by the Fund in repurchase agreements until such time as it may
otherwise be invested or used for payments of obligations of the Fund. A
repurchase agreement may be viewed as a type of secured lending by the Fund
which typically involves the acquisition by the Fund of government securities
from a selling financial institution such as a bank, savings and loan
association or broker-dealer. The agreement provides that the Fund will sell
back to the institution, and that the institution will repurchase. the
underlying security ("collateral") at a specified price and at a fixed time in
the future, usually not more than seven days from the date of purchase. The
collateral will be maintained in a segregated account and will be marked to
market daily to determine that the full value of the collateral, as specified in
the agreement, does not decrease below the repurchase price plus accrued
interest. If such decrease occurs, additional collateral will be added to the
account to maintain full collateralization. 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 and may exceed one year.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. Repurchase agreements will be transacted only with large,
well-capitalized and well-established financial institutions whose financial
condition will be continuously monitored by the Investment Manager subject to
procedures established by the Trustees. 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 the sale upon a
default of the obligation to repurchase were less than the repurchase price, the
Fund could suffer a loss. The Fund has not to date and does not presently intend
to enter into repurchase agreements so that more than 5% of the Fund's net
assets are subject to such agreements.
 
    REVERSE REPURCHASE AGREEMENTS.  The Fund may also use reverse repurchase
agreements 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 otherwise obtaining the cash. Opportunities
to achieve this advantage may not always be available. 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. Reverse repurchase
agreements are considered borrowings by the Fund and for purposes other than
meeting redemptions may not exceed 5% of the Fund's total assets.
 
    WARRANTS.  The Fund may acquire warrants attached to other securities and,
in addition may invest up to 5% of the value of its total assets in warrants,
including up to 2% of such assets in warrants not
 
                                       14
<PAGE>
listed on either the New York or American Stock Exchange. Warrants are, in
effect, an option to purchase equity securities at a specific price, generally
valid for a specific period of time, and have no voting rights, pay no dividends
and have no rights with respect to the corporation issuing them.
 
    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 or 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 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.
 
    WHEN, AS AND IF ISSUED SECURITIES.  As discussed in the Prospectus, the Fund
may purchase securities on a "when, as and if issued" basis under which the
issuance of the security depends upon the occurrence of a subsequent event, such
as approval of a merger, corporate reorganization, leveraged buyout or debt
restructuring. The commitment for the purchase of any such security will not be
recognized in the portfolio of the Fund until the Investment Manager determines
that issuance of the security is probable. At such time, the Fund will record
the transaction and, in determining its net asset value, will reflect the value
of the security daily. At such time, the Fund will also establish a segregated
account with its custodian bank in which it will continuously maintain cash or
U.S. Government securities or other liquid portfolio securities equal in value
to recognized commitments for such securities. Settlement of the trade will
occur within five business days of the occurrence of the subsequent event. The
value of the Fund's commitments to purchase the securities of any one issuer,
together with the value of all securities of such issuer owned by the Fund, may
not exceed 5% of the value of the Fund's total assets at the time the initial
commitment to purchase such securities is made (see "Investment Restrictions").
Subject to the foregoing restrictions, the Fund may purchase securities on such
basis without limit. An increase in the percentage of the Fund's assets
committed to the purchase of securities on a "when, as and if issued" basis may
increase the volatility of its net asset value. The Investment Manager and the
Trustees do not believe that the net asset value of the Fund will be adversely
affected by its purchase of securities on such basis.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund may write covered call options against securities held in its
portfolio and covered put options on eligible portfolio securities and stock
indexes and purchase options of the same series to effect closing transactions,
and may hedge against potential changes in the market value of investments (or
anticipated investments) and facilitate the reallocation of the Fund's assets
into and out of equities and fixed-income securities by purchasing put and call
options on portfolio (or eligible portfolio) securities and engaging in
transactions involving futures contracts and options on such contracts.
 
    Call and put options on U.S. Treasury notes, bonds and bills and equity
securities are listed on Exchanges (currently the Chicago Board Options
Exchange, American Stock Exchange, New York Stock Exchange, Pacific Stock
Exchange and Philadelphia Stock Exchange) and are written in over-the-counter
transactions ("OTC Options"). Listed options are issued by the Options Clearing
Corporation
 
                                       15
<PAGE>
("OCC"). Ownership of a listed call option gives the Fund the right to buy from
the OCC the underlying security covered by the option at the stated exercise
price (the price per unit of the underlying security) by filing an exercise
notice prior to the expiration date of the option. The writer (seller) of the
option would then have the obligation to sell to the OCC the underlying security
at that exercise price prior to the expiration date of the option, regardless of
its then current market price. Ownership of a listed put option would give the
Fund the right to sell the underlying security to the OCC at the stated exercise
price. Upon notice of exercise of the put option, the writer of the put would
have the obligation to purchase the underlying security from the OCC at the
exercise price.
 
    OPTIONS ON TREASURY BONDS AND NOTES.  Because trading interest in options
written on Treasury bonds and notes tends to center on the most recently
auctioned issues, the exchanges on which such securities trade will not continue
indefinitely to introduce options with new expirations to replace expiring
options on particular issues. Instead, the expirations introduced at the
commencement of options trading on a particular issue will be allowed to run
their course, with the possible addition of a limited number of new expirations
as the original ones expire. Options trading on each issue of bonds or notes
will thus be phased out as new options are listed on more recent issues, and
options representing a full range of expirations will not ordinarily be
available for every issue on which options are traded.
 
    OPTIONS ON TREASURY BILLS.  Because a deliverable Treasury bill changes from
week to week, writers of Treasury bill calls cannot provide in advance for their
potential exercise settlement obligations by acquiring and holding the
underlying security. However, if the Fund holds a long position in Treasury
bills with a principal amount of the securities deliverable upon exercise of the
option, the position may be hedged from a risk standpoint by the writing of a
call option. For so long as the call option is outstanding, the Fund will hold
the Treasury bills in a segregated account with its Custodian, so that they will
be treated as being covered.
 
    OPTIONS ON GNMA CERTIFICATES.  Currently, options on GNMA Certificates are
only traded over-the-counter. Since the remaining principal balance of GNMA
Certificates declines each month as a result of mortgage payments, the Fund, as
a writer of a GNMA call holding GNMA Certificates as "cover" to satisfy its
delivery obligation in the event of exercise, may find that the GNMA
Certificates it holds no longer have a sufficient remaining principal balance
for this purpose. Should this occur, the Fund will purchase additional GNMA
Certificates from the same pool (if obtainable) or replacement GNMA Certificates
in the cash market in order to maintain its cover. A GNMA Certificate held by
the Fund to cover an option position in any but the nearest expiration month may
cease to represent cover for the option in the event of a decline in the GNMA
coupon rate at which new pools are originated under the FHA/VA loan ceiling in
effect at any given time, as such decline may increase the prepayments made on
other mortgage pools. If this should occur, the Fund will no longer be covered,
and the Fund will either enter into a closing purchase transaction or replace
such Certificate with a Certificate which represents cover. When the Fund closes
out its position or replaces such Certificate, it may realize a loss and incur
transaction costs.
 
    OTC OPTIONS.  Exchange-listed options are issued by the OCC which assures
that all transactions in such options are properly executed. OTC options are
purchased from or sold (written) to dealers or financial institutions which have
entered into direct agreements with the Fund. With OTC options, such variables
as expiration date, exercise price and premium will be agreed upon between the
Fund and the transacting dealer, without the intermediation of a third party
such as the OCC. If the transacting dealer fails to make or take delivery of the
securities underlying an option it has written, in accordance with the terms of
that option, the Fund would lose the premium paid for the option as well as any
anticipated benefit of the transaction. The Fund will engage in OTC option
transactions only with primary U.S. Government securities dealers recognized by
the Federal Reserve Bank of New York.
 
                                       16
<PAGE>
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on portfolio securities and on stock index options, without limit, in order to
aid in achieving its investment objective. Generally, a call option is "covered"
if the Fund owns, or has the right to acquire, without additional cash
consideration (or for additional cash consideration held for the Fund by its
Custodian in a segregated account) the underlying security subject to the option
except that in the case of call options on U.S. Treasury Bills, the Fund might
own U.S. Treasury Bills of a different series from those underlying the call
option, but with a principal amount and value corresponding to the exercise
price and a maturity date no later than that of the securities deliverable under
the call option. A call option is also covered if the Fund holds a call on the
same security as the underlying security of the written option, where the
exercise price of the call used for coverage is equal to or less than the
exercise price of the call written or greater than the exercise price of the
call written if the mark-to-market difference is maintained by the Fund in cash,
U.S. Government securities or other liquid portfolio securities which the Fund
holds in a segregated account maintained with its Custodian.
 
    The Fund will receive from the purchaser, in return for a call it has
written, a "premium"; i.e., the price of the option. Receipt of these premiums
may better enable the Fund to achieve a greater total return than would be
realized from holding the underlying securities alone. Moreover, the premium
received will offset a portion of the potential loss incurred by the Fund if the
securities underlying the option are ultimately sold by the Fund at a loss. The
value of the premium received will fluctuate with varying economic market
conditions.
 
    As regards listed options and certain OTC options, during the option period,
the Fund may be required, at any time, to deliver the underlying security
against payment of the exercise price on any calls it has written (exercise of
certain listed and OTC options may be limited to specific expiration dates).
This obligation is terminated upon the expiration of the option period or at
such earlier time when the writer effects a closing purchase transaction. A
closing purchase transaction is accomplished by purchasing an option of the same
series as the option previously written.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an outstanding call option to prevent an underlying security from being called,
to permit the sale of an underlying security or to enable the Fund to write
another call option on the underlying security with either a different exercise
price or expiration date or both. Also, effecting a closing purchase transaction
will permit the cash or proceeds from the concurrent sale of any securities
subject to the option to be used for other investments by the Fund. The Fund may
realize a net gain or loss from a closing purchase transaction depending upon
whether the amount of the premium received on the call option is more or less
than the cost of effecting the closing purchase transaction. Any loss incurred
in a closing purchase transaction may be wholly or partially offset by
unrealized appreciation in the market value of the underlying security.
Conversely, a gain resulting from a closing purchase transaction could be offset
in whole or in part or exceeded by a decline in the market value of the
underlying security.
 
    If a call option expires unexercised, the Fund realizes a gain in the amount
of the premium on the option less the commission paid. Such a gain, however, may
be offset by depreciation in the market value of the underlying security during
the option period. If a call option is exercised, the Fund realizes a gain or
loss from the sale of the underlying security equal to the difference between
the purchase price of the underlying security and the proceeds of the sale of
the security plus the premium received for on the option less the commission
paid.
 
    Options written by a Fund normally have expiration dates of from up to nine
months (equity securities) to eighteen months (fixed-income securities) from the
date written. The exercise price of a call option may be below, equal to or
above the current market value of the underlying security at the time the option
is written. See "Risks of Options and Futures Transactions," below.
 
    The Fund may also purchase put options to close out written put positions in
a manner similar to call options closing purchase transactions. In addition, the
Fund may sell a put option which it has previously purchased prior to the sale
of the securities underlying such option. Such a sale would result in a net gain
or loss depending on whether the amount received on the sale is more or less
than the premium
 
                                       17
<PAGE>
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.
 
    COVERED PUT WRITING.  As a writer of a covered put option, the Fund incurs
an obligation to buy the security underlying the option from the purchaser of
the put, at the option's exercise price at any time during the option period, at
the purchaser's election (certain listed and OTC put options written by the Fund
will be exercisable by the purchaser only on a specific date). A put is
"covered" if the Fund maintains, in a segregated account maintained on its
behalf at the Fund's Custodian, cash, U.S. Government securities or other liquid
portfolio securities in an amount equal to at least the exercise price of the
option, at all times during the option period. Similarly, a written put position
could be covered by the Fund by its purchase of a put option on the same
security as the underlying security of the written option, where the exercise
price of the purchased option is equal to or more than the exercise price of the
put written or less than the exercise price of the put written if the
mark-to-market difference is maintained by the Fund in cash, U.S. Government
securities or other liquid portfolio securities which the Fund holds in a
segregated account maintained at its Custodian. In the case of listed options,
during the option period, the Fund may be required, at any time, to make payment
of the exercise price against delivery of the underlying security. The operation
of and limitations on covered put options in other respects are substantially
identical to those of call options.
 
    The Fund will write put options for two purposes: (1) to receive the income
derived from the premiums paid by purchasers; and (2) when the Investment
Manager wishes to purchase the security underlying the option at a price lower
than its current market price, in which case it will write the covered put at an
exercise price reflecting the lower purchase price sought. The potential gain on
a covered put option is limited to the premium received on the option (less the
commissions paid on the transaction) while the potential loss equals the
difference between the exercise price of the option and the current market price
of the underlying securities when the put is exercised, offset by the premium
received (less the commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC call
and put options in amounts equalling up to 5% of its total assets. The Fund may
purchase call options in order to close out a covered call position (see
"Covered Call Writing" above) and, as to 2% of its total assets, purchase call
options on securities it intends to purchase. If, in the latter case, the price
of the security underlying the option fails to rise above the exercise price by
an amount exceeding the price of the option premium, the Fund will sustain a
loss equal to some or all of the premium price. A call purchased to close out a
position is likely to be on the same securities and have the same terms as the
written option. The option would generally be acquired from the dealer or
financial institution which purchased the call written by the Fund.
 
    The Fund may purchase put options on securities which it holds (or has the
right to acquire) in its portfolio only to protect itself against a decline in
the value of the security. If the value of the underlying security were to fall
below the exercise price of the put purchased in an amount greater than the
premium paid for the option, the Fund would incur no additional loss. The Fund
may also purchase put options to close out written put positions in a manner
similar to call options closing purchase transactions. In addition, the Fund may
sell a put option which it has previously purchased prior to the sale of the
securities underlying such option. Such a sale would result in a net gain or
loss depending on whether the amount received on the sale is more or less than
the premium and other transaction costs paid on the put option when it was
purchased. 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.  The successful use of options depends on the
ability of the Investment Manager to forecast correctly interest rates and
market movements. If the market value of the portfolio securities upon which
call options have been written increases, the Fund may receive a lower total
return from the portion of its portfolio upon which calls have been written than
it would have had
 
                                       18
<PAGE>
such calls not been written. In writing puts, the Fund assumes the risk of loss
should the market value of the underlying securities decline below the exercise
price of the option (any loss being decreased by the receipt of the premium on
the option written). During the option period, the covered call writer has, in
return for the premium on the option, given up the opportunity for capital
appreciation above the exercise price should the market price of the underlying
security increase, but has retained the risk of loss should the price of the
underlying security decline. The secured put writer also retains the risk of
loss should the market value of the underlying security decline below the
exercise price of the option less the premium received on the sale of the
option. In both cases, the writer has no control over the time when it may be
required to fulfill its obligation as a writer of the option. Once an option
writer has received an exercise notice, it cannot effect a closing purchase
transaction in order to terminate its obligation under the option and must
deliver or receive the underlying securities at the exercise price.
 
    Prior to exercise or expiration, an option position can only be terminated
by entering into a closing purchase or sale transaction. If a covered call
option writer is unable to effect a closing purchase transaction or to purchase
an offsetting OTC option, it cannot sell the underlying security until the
option expires or the option is exercised. Accordingly, a covered call option
writer may not be able to sell an underlying security at a time when it might
otherwise be advantageous to do so. A covered put option writer who is unable to
effect a closing purchase transaction or to purchase an offsetting over-the-
counter option would continue to bear the risk of decline in the market price of
the underlying security until the option expires or is exercised. In addition, a
covered put writer would be unable to utilize the amount held in cash or U.S.
Government or other liquid portfolio securities as cover for the put option for
other investment purposes until the exercise or expiration of the option.
 
    The Fund's ability to close out its position as a writer of an option is
dependent upon the existence of a liquid secondary market on option exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC options, as such options will generally only be closed out by entering into
a closing purchase transaction with the purchasing dealer. However, the Fund may
be able to purchase an offsetting option which does not close out its position
as a writer but constitutes an asset of equal value to the obligation under the
option written. If the Fund is not able to either enter into a closing purchase
transaction or purchase an offsetting position, it will be required to maintain
the securities subject to the call, or the collateral underlying the put, even
though it might not be advantageous to do so, until a closing transaction can be
entered into (or the option is exercised or expires).
 
    Among the possible reasons for the absence of a liquid secondary market on
an exchange are: (i) insufficient trading interest in certain options; (ii)
restrictions on transactions imposed by an exchange; (iii) trading halts,
suspensions or other restrictions imposed with respect to particular classes or
series of options or underlying securities; (iv) interruption of the normal
operations on an exchange; (v) inadequacy of the facilities of an exchange or
the Options Clearing Corporation ("OCC") to handle current trading volume; or
(vi) a decision by one or more exchanges to discontinue the trading of options
(or a particular class or series of options), in which event the secondary
market on that exchange (or in that class or series of options) would cease to
exist, although outstanding options on that exchange that had been issued by the
OCC as a result of trades on that exchange would generally continue to be
exercisable in accordance with their terms.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in options, the Fund could experience delays and/or losses in
liquidating open positions purchased or sold through the broker and/or incur a
loss of all or part of its margin deposits with the broker. Similarly, in the
event of the bankruptcy of the writer of an OTC option purchased by the Fund,
the Fund could experience a loss of all or part of the value of the option.
Transactions are entered into by the Fund only with brokers or financial
institutions deemed creditworthy by the Investment Manager.
 
    Each of the exchanges has established limitations governing the maximum
number of call or put options on the same underlying security or futures
contract (whether or not covered) which may be written by a single investor,
whether acting alone or in concert with others (regardless of whether such
options are written on the same or different exchanges or are held or written on
one or more accounts or
 
                                       19
<PAGE>
through one or more brokers). An exchange may order the liquidation of positions
found to be in violation of these limits and it may impose other sanctions or
restrictions. These position limits may restrict the number of listed options
which the Fund may write.
 
    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.
 
    The extent to which the Fund may enter into transactions involving options
may be limited by the Internal Revenue Code's requirements for qualification as
a regulated investment company and the Fund's intention to qualify as such (see
"Dividends, Distributions and Taxes" in the Prospectus).
 
    STOCK INDEX OPTIONS.  Options on stock indexes are similar to options on
stock except that, rather than the right to take or make delivery of stock at a
specified price, an option on a stock index gives the holder the right to
receive, upon exercise of the option, an amount of cash if the closing level of
the stock index upon which the option is based is greater than, in the case of a
call, or less than, in the case of a put, the exercise price of the option. This
amount of cash is equal to such difference between the closing price of the
index and the exercise price of the option expressed in dollars times a
specified multiple (the "multiplier"). The multiplier for an index option
performs a function similar to the unit of trading for a stock option. It
determines the total dollar value per contract of each point in the difference
between the exercise price of an option and the current level of the underlying
index. A multiplier of 100 means that a one-point difference will yield $100.
Options on different indexes may have different multipliers. The writer of the
option is obligated, in return for the premium received, to make delivery of
this amount. Unlike stock options, all settlements are in cash and a gain or
loss depends on price movements in the stock market generally (or in a
particular segment of the market) rather than the price movements in individual
stocks. Currently, options are traded on, among other indexes, the Standard &
Poor's 100 Index and the Standard & Poor's 500 Index on the Chicago Board
Options Exchange, the Major Market Index and the Computer Technology Index, Oil
Index and Institutional Index on the American Stock Exchange and the NYSE Index
and NYSE Beta Index on the New York Stock Exchange, The Financial News Composite
Index on the Pacific Stock Exchange and the Value Line Index, National O-T-C
Index and Utilities Index on the Philadelphia Stock Exchange, each of which and
any similar index on which options are traded in the future which include stocks
that are not limited to any particular industry or segment of the market is
referred to as a "broadly based stock market index." The Fund will invest only
in broadly based indexes. Options on broad-based stock indexes provide the Fund
with a means of protecting the Fund against the risk of market-wide price
movements. If the Investment Manager anticipates a market decline, the Fund
could purchase a stock index put option. If the expected market decline
materialized, the resulting decrease in the value of the Fund's portfolio would
be offset to the extent of the increase in the value of the put option. If the
Investment Manager anticipates a market rise, the Fund may purchase a stock
index call option to enable the Fund to participate in such rise until
completion of anticipated common stock purchases by the Fund. Purchases and
sales of stock index options also enable the Investment Manager to more speedily
achieve changes in the Fund's equity positions.
 
    The Fund will be able to write put options on stock indexes only if such
positions are covered by cash, U.S. Government securities or other liquid
portfolio securities equal to the aggregate exercise price of the puts, or by a
put option on the same stock index with a strike price no lower than the strike
price of the put option sold by the Fund, which cover is held for the Fund in a
segregated account maintained for it by the Fund's Custodian. All call options
on stock indexes written by the Fund will be covered either by a portfolio of
stocks substantially replicating the movement of the index underlying the call
option or by holding a separate call option on the same stock index with a
strike price no higher than the strike price of the call option sold by the
Fund.
 
    RISKS OF OPTIONS ON INDEXES.  Because exercises of stock index options are
settled in cash, the Fund, as a call writer, would not be able to provide in
advance for their potential settlement obligations by
 
                                       20
<PAGE>
acquiring and holding the underlying securities. A call writer can offset some
of the risk of its writing position by holding a diversified portfolio of stocks
similar to those on which the underlying index is based. However, most investors
cannot, as a practical matter, acquire and hold a portfolio containing exactly
the same stocks as the underlying index, and, as a result, bear a risk that the
value of the securities held will vary from the value of the index. Even if an
index call writer could assemble a stock portfolio that exactly reproduced the
composition of the underlying index, the writer still would not be fully covered
from a risk standpoint because of the "timing risk" inherent in writing index
options. When an index option is exercised, the amount of cash that the holder
is entitled to receive is determined by the difference between the exercise
price and the closing index level on the date when the option is exercised. As
with other kinds of options, the writer will not learn that it has been assigned
until the next business day, at the earliest. The time lag between exercise and
notice of assignment poses no risk for the writer of a covered call on a
specific underlying security, such as a common stock, because there the writer's
obligation is to deliver the underlying security, not to pay its value as of a
fixed time in the past. So long as the writer already owns the underlying
security, it can satisfy its settlement obligations by simply delivering it, and
the risk that its value may have declined since the exercise date is borne by
the exercising holder. In contrast, even if the writer of an index call holds
stocks that exactly match the composition of the underlying index, it will not
be able to satisfy its assignment obligations by delivering those stocks against
payment of the exercise price. Instead, it will be required to pay cash in an
amount based on the closing index value on the exercise date; and by the time it
learns that it has been assigned, the index may have declined with a
corresponding decrease in the value of its stock portfolio. This "timing risk"
is an inherent limitation on the ability of index call writers to cover their
risk exposure by holding stock positions.
 
    A holder of an index option who exercises it before the closing index value
for that day is available runs the risk that the level of the underlying index
may subsequently change. If such a change causes the exercised option to fall
out-of-the-money, the exercising holder will be required to pay the difference
between the closing index value and the exercise price of the option (times the
applicable multiplier) to the assigned writer.
 
    If dissemination of the current level of an underlying index is interrupted,
or if trading is interrupted in stocks accounting for a substantial portion of
the value of an index, the trading of options on that index will ordinarily be
halted. If the trading of options on an underlying index is halted, an exchange
may impose restrictions prohibiting the exercise of such options.
 
    FUTURES CONTRACTS.  As stated in the Prospectus, the Fund may purchase and
sell interest rate and stock index futures contracts ("futures contracts") that
are traded on U.S. commodity exchanges on such underlying securities as U.S.
Treasury bonds, notes, bills and GNMA Certificates ("interest rate futures") and
such indexes as the S&P 500 Index, the Moody's Investment-Grade Corporate Bond
Index and the New York Stock Exchange Composite Index ("index futures").
 
    As a futures contract purchaser, the Fund incurs an obligation to take
delivery of a specified amount of the obligation underlying the contract at a
specified time in the future for a specified price. As a seller of a futures
contract, the Fund incurs an obligation to deliver the specified amount of the
underlying obligation at a specified time in return for an agreed upon price.
 
    The Fund will purchase or sell interest rate futures contracts and bond
index futures contracts for the purpose of hedging its fixed-income portfolio
(or anticipated portfolio) against changes in prevailing interest rates and to
alter the Fund's asset allocation in fixed-income securities. If the Investment
Manager anticipates that interest rates may rise and, concomitantly, the price
of fixed-income securities fall, or wishes to decrease the Fund's asset
allocation in fixed-income securities, the Fund may sell an interest rate
futures contract or a bond index futures contract. If declining interest rates
are anticipated or if the Investment Manager wishes to increase the Fund's asset
allocation of fixed-income securities, the Fund may purchase an interest rate
futures contract to protect against a potential increase in the price of
 
                                       21
<PAGE>
U.S. Government securities the Fund intends to purchase. Subsequently,
appropriate fixed-income securities may be purchased by the Fund in an orderly
fashion; as securities are purchased, corresponding futures positions would be
terminated by offsetting sales of contracts.
 
    The Fund will purchase or sell stock index futures contracts for the purpose
of hedging its equity portfolio (or anticipated portfolio) against changes in
their prices. If the Investment Manager anticipates that the prices of stock
held by the Fund may fall or wishes to decrease the Fund's asset allocation in
equity securities, the Fund may sell a stock index futures contract. Conversely,
if the Investment Manager wishes to increase the Fund's assets which are
invested in stocks or as a hedge against anticipated price rises in those stocks
which the Fund intends to purchase, the Fund may purchase stock index futures
contracts. This allows the Fund to purchase equities, in accordance with the
Investment Manager's asset allocations, in an orderly and efficacious manner. In
addition, interest rate and stock index futures contracts will be bought or sold
in order to close out a short or long position in a corresponding futures
contract.
 
    Although most interest rate futures contracts call for actual delivery or
acceptance of securities, the contracts usually are closed out before the
settlement date without the making or taking of delivery. Stock index futures
contracts provide for the delivery of an amount of cash equal to a specified
dollar amount times the difference between the stock index value at the open or
close of the last trading day of the contract and the futures contract price. A
futures contract sale is closed out by effecting a futures contract purchase for
the same aggregate amount of the specific type of equity security and the same
delivery date. If the sale price exceeds the offsetting purchase price, the
seller would be paid the difference and would realize a gain. If the offsetting
purchase price exceeds the sale price, the seller would pay the difference and
would realize a loss. Similarly, a futures contract purchase is closed out by
effecting a futures contract sale for the same aggregate amount of the specific
type of equity security and the same delivery date. If the offsetting sale price
exceeds the purchase price, the purchaser would realize a gain, whereas if the
purchase price exceeds the offsetting sale price, the purchaser would realize a
loss. There is no assurance that the Fund will be able to enter into a closing
transaction.
 
    INTEREST RATE FUTURES.  When the Fund enters into an interest rate futures
contract, it is initially required to deposit with the Fund's Custodian, in a
segregated account in the name of the broker performing the transaction, "an
initial margin" of cash or U.S. Government securities or other liquid portfolio
securities equal to approximately 2% of the contract amount. Initial margin
requirements are established by the Exchanges on which futures contracts trade
and may, from time to time, change. In addition, brokers may establish margin
deposit requirements in excess of those required by the Exchanges.
 
    Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing of
funds by a broker's 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 of cash or U.S. Government
securities called "variation margin," with the Fund's futures contract clearing
broker, which are reflective of price fluctuations in the futures contract.
Currently, interest rate futures contracts can be purchased on debt securities
such as U.S. Treasury Bills and Bonds, U.S. Treasury Notes with maturities
between 6 1/2 and 10 years, GNMA Certificates and Bank Certificates of Deposit.
 
    INDEX FUTURES.  As discussed in the Prospectus, the Fund may invest in index
futures contracts. An index futures contract sale creates an obligation by the
Fund, as seller, to deliver cash at a specified future time. An index futures
contract purchase would create an obligation by the Fund, as purchaser, to take
delivery of cash at a specified future time. Futures contracts on indexes do not
require the physical delivery of securities, but provide for a final cash
settlement on the expiration date which reflects accumulated profits and losses
credited or debited to each party's account.
 
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects index futures contracts in a manner similar to that
described above for interest rate futures contracts. Currently,
 
                                       22
<PAGE>
the initial margin requirements range from 3% to 10% of the contract amount for
index futures. In addition, due to current industry practice, daily variations
in gains and losses on open contracts are required to be reflected in cash in
the form of variation margin payments. The Fund may be required to make
additional margin payments during the term of the contract.
 
    At any time prior to expiration of the futures contract, the Fund may elect
to close the position by taking an opposite position which will operate to
terminate the Fund's position in the futures contract. A final determination of
variation margin is then made, additional cash is required to be paid by or
released to the Fund and the Fund realizes a loss or a gain.
 
    Currently, index futures contracts can be purchased or sold with respect to,
among others, the Standard & Poor's 500 Stock Price Index and the Standard &
Poor's 100 Stock Price Index on the Chicago Mercantile Exchange, the New York
Stock Exchange Composite Index on the New York Futures Exchange, the Major
Market Index on the American Stock Exchange, the Value Line Stock Index on the
Kansas City Board of Trade and the Moody's Investment-Grade Corporate Bond Index
on the Chicago Board of Trade.
 
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts which are traded on an Exchange and enter into
closing transactions with respect to such options to terminate an existing
position. An option on a futures contract gives the purchaser the right (in
return for the premium paid), to assume a position in a futures contract (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price at any time during the term of the option. Upon
exercise of the option, the delivery of the futures position by the writer of
the option to the holder of the option is accompanied by delivery of the
accumulated balance in the writer's futures margin account, which represents the
amount by which the market price of the futures contract at the time of exercise
exceeds, in the case of a call, or is less than, in the case of a put, the
exercise price of the option on the futures contract.
 
    The Fund will purchase and write options on futures contracts for identical
purposes to those set forth above for the purchase of a futures contract
(purchase of a call option or sale of a put option) and the sale of a futures
contract (purchase of a put option or sale of a call option), or to close out a
long or short position in futures contracts. If, for example, the Investment
Manager wished to protect against an increase in interest rates and the
resulting negative impact on the value of a portion of its fixed-income
portfolio, it might write a call option on an interest rate futures contract,
the underlying security of which correlates with the portion of the portfolio
the Investment Manager seeks to hedge. Any premiums received in the writing of
options on futures contracts may, of course, augment the total return of the
Fund and thereby provide a further hedge against losses resulting from price
declines in portions of the Fund's portfolio.
 
    The writer of an option on a futures contract is required to deposit initial
and variation margin pursuant to requirements similar to those applicable to
futures contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.
 
    LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS ON FUTURES.  The Fund may not
enter into futures contracts or purchase related options thereon if, immediately
thereafter, the amount committed to initial margin plus the amount paid for
premiums for unexpired options on futures contracts exceeds 5% of the value of
the Fund's total assets, after taking into account unrealized gains and
unrealized losses on such contracts it has entered into, provided, however, that
in the case of an option that is in-the-money (the exercise price of the call
(put) option is less (more) than the market price of the underlying security) at
the time of purchase, the in-the-money amount may be excluded in calculating the
5%. However, there is no overall limitation on the percentage of the Fund's
assets which may be subject to a hedge position. In addition, in accordance with
the regulations of the Commodity Futures Trading Commission ("CFTC") under which
the Fund is exempted from registration as a commodity pool operator, the Fund
may only enter into futures contracts and options on futures contracts
transactions for purposes of hedging a part or all of its portfolio. If the CFTC
changes its regulations so that the Fund would be permitted to write
 
                                       23
<PAGE>
options on futures contracts for purposes other than hedging the Fund's
investments without CFTC registration, the Fund may engage in such transactions
for those purposes. Except as described above, there are no other limitations on
the use of futures and options thereon by the Fund.
 
    RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS.  The
successful use of futures and related options depends on the ability of the
Investment Manager to accurately predict market and interest rate movements. As
stated in the prospectus, the Fund may sell a futures contract to protect
against the decline in the value of securities held by the Fund. However, it is
possible that the futures market may advance and the value of securities held in
the portfolio of the Fund may decline. If this occurred, the Fund would lose
money on the futures contract and also experience a decline in value of its
portfolio securities. However, while this could occur for a very brief period or
to a very small degree, over time the value of a diversified portfolio will tend
to move in the same direction as the futures contracts.
 
    If the Fund purchases a futures contract to hedge against the increase in
value of securities it intends to buy, and the value of such securities
decreases, then the Investment Manager 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 or has sold a
call option on a futures contract, it will cover this position by holding, in a
segregated account maintained at its Custodian, cash, U.S. Government securities
or other high grade debt obligations equal in value (when added to any initial
or variation margin on deposit) to the market value of the securities underlying
the futures contract or the exercise price of the option. Such a position may
also be covered by owning the securities underlying the futures contract (in the
case of a stock index futures contract a portfolio of securities substantially
replicating the relevant index), or by holding a call option permitting the Fund
to purchase the same contract at a price no higher than the price at which the
short position was established.
 
    In addition, if the Fund holds a long position in a futures contract or has
sold a put option on a futures contract, it will hold cash, U.S. Government
securities or other liquid portfolio securities equal to the purchase price of
the contract or the exercise price of the put option (less the amount of initial
or variation margin on deposit) in a segregated account maintained for the Fund
by its Custodian. Alternatively, the Fund could cover its long position by
purchasing a put option on the same futures contract with an exercise price as
high or higher than the price of the contract held by the Fund.
 
    Exchanges limit the amount by which the price of a futures contract may move
on any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased. In the event of adverse price movements, the Fund would continue to
be required to make daily cash payments of variation margin on open futures
positions. In such situations, if the Fund has insufficient cash, it may have to
sell portfolio securities to meet daily variation margin requirements at a time
when it may be disadvantageous to do so. In addition, the Fund may be required
to take or make delivery of the instruments underlying interest rate futures
contracts it holds at a time when it is disadvantageous to do so. The inability
to close out options and futures positions could also have an adverse impact on
the Fund's ability to effectively hedge its portfolio.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in futures or options thereon, the Fund could experience delays
and/or losses in liquidating open positions purchased or sold through the broker
and/or incur a loss of all or part of its margin deposits with the broker.
Similarly, in the event of the bankruptcy of the writer of an OTC option
purchased by the Fund, the Fund could experience a loss of all or part of the
value of the option. Transactions are entered into by the Fund only with brokers
or financial institutions deemed creditworthy by the Investment Manager.
 
    While the futures contracts and options transactions to be engaged in by the
Fund for the purpose of hedging the Fund's portfolio securities are not
speculative in nature, there are risks inherent in the use of such instruments.
One such risk which may arise in employing futures contracts to protect against
the
 
                                       24
<PAGE>
price volatility of portfolio securities is that the prices of securities and
indexes subject to futures contracts (and thereby the futures contract prices)
may correlate imperfectly with the behavior of the cash prices of the Fund's
portfolio securities. Another such risk is that prices of interest rate futures
contracts may not move in tandem with the changes in prevailing interest rates
against which the Fund seeks a hedge. A correlation may also be distorted by the
fact that the futures market is dominated by short-term traders seeking to
profit from the difference between a contract or security price objective and
their cost of borrowed funds. Such distortions are generally minor and would
diminish as the contract approached maturity.
 
    There may exist an imperfect correlation between the price movements of
futures contracts purchased by the Fund and the movements in the prices of the
securities which are the subject of the hedge. If participants in the futures
market elect to close out their contracts through offsetting transactions rather
than meet margin deposit requirements, distortions in the normal relationship
between the debt securities and futures markets could result. Price distortions
could also result if investors in futures contracts opt to make or take delivery
of underlying securities rather than engage in closing transactions due to the
resultant reduction in the liquidity of the futures market. In addition, due to
the fact that, from the point of view of speculators, the deposit requirements
in the futures markets are less onerous than margin requirements in the cash
market, increased participation by speculators in the futures market could cause
temporary price distortions. Due to the possibility of price distortions in the
futures market and because of the imperfect correlation between movements in the
prices of securities and movements in the prices of futures contracts, a correct
forecast of interest rate trends by the Investment Manager may still not result
in a successful hedging transaction.
 
    There is no assurance that a liquid secondary market will exist for futures
contracts and related options in which the Fund may invest. In the event a
liquid market does not exist, it may not be possible 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.
 
    The extent to which the Fund may enter into transactions involving futures
contracts and options thereon may be limited by the Internal Revenue Code's
requirements for qualification as a regulated investment company and the Fund's
intention to qualify as such (see "Dividends, Distributions and Taxes" in the
Prospectus).
 
    Compared to the purchase or sale of futures contracts, the purchase of call
or put options on futures contracts involves less potential risk to the Fund
because the maximum amount at risk is the premium paid for the options (plus
transaction costs). However, there may be circumstances when the purchase of a
call or put option on a futures contract would result in a loss to the Fund
notwithstanding that the purchase or sale of a futures contract would not result
in a loss, as in the instance where there is no movement in the prices of the
futures contract or underlying securities.
 
    The Investment Manager has substantial experience in the use of the
investment techniques described above under the heading "Options and Futures
Transactions," which techniques require skills different from those needed to
select the portfolio securities underlying various options and futures
contracts.

INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment restrictions listed below have been adopted by the Fund as
fundamental policies, except as otherwise indicated. Under the Act, a
fundamental policy may not be changed without the vote of a majority of the
outstanding voting securities of the Fund, as defined in the Act. Such a
majority is defined as the lesser of (a) 67% or more of the shares present at a
meeting of shareholders, if the holders of 50% of the outstanding shares of the
Fund are present or represented by proxy or (b) more than 50% of the outstanding
shares of the Fund.
 
    The Fund may not:
 
         1.    Invest in securities of any issuer if, to the knowledge of the
    Fund, any officer or trustee/ director of the Fund or of the Investment
    Manager owns more than 1/2 of 1% of the outstanding securities of such
    issuer, and such officers and trustees/directors who own more than 1/2 of 1%
    own in the aggregate more than 5% of the outstanding securities of such
    issuers.
 
         2.    Purchase or sell real estate or interests therein, although the
    Fund may purchase securities of issuers which engage in real estate
    operations and securities secured by real estate or interests therein.
 
         3.    Invest more than 10% of its total assets in "illiquid securities"
    (securities for which market quotations are not readily available) and
    repurchase agreements which have a maturity of longer than seven days. The
    staff of the Securities and Exchange Commission ("SEC") has taken the
    position that purchased OTC options and the assets used as "cover" for
    written OTC options are illiquid securities and the Fund will treat these
    assets as such.
 
         4.    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.
 
         5.    Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets.
 
         6.    Borrow money (except insofar as to the Fund may be deemed to have
    borrowed by entrance into a reverse repurchase agreement), except that the
    Fund may, but not to leverage the Fund's assets, borrow from a bank for
    temporary or emergency purposes in amounts not exceeding 5% (taken at the
    lower of cost or current value) of its total assets (not including the
    amount borrowed).
 
         7.    Pledge its assets or assign or otherwise encumber them except to
    secure borrowings effected within the limitations set forth in restriction
    (6). For the purpose of this restriction, collateral arrangements with
    respect to the writing of options and collateral arrangements with respect
    to initial or variation margin for futures are not deemed to be pledges of
    assets.
 
         8.    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
    borrowing money in accordance with restrictions described above.
 
         9.    Make loans of money or securities, except: (a) by the purchase of
    publicly distributed debt obligations in which the Fund may invest
    consistent with its investment objective and policies; (b) by investment in
    repurchase agreements; or (c) by lending its portfolio securities.
 
        10.   Make short sales of securities.
 
        11.   Purchase securities on margin, except for such short-term loans as
    are necessary for the clearance of portfolio securities. The deposit or
    payment by the Fund of initial or variation margin in connection with
    futures contracts or related options thereon is not considered the purchase
    of a security on margin.
 
                                       26
<PAGE>
        12.   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.
 
        13.   Invest for the purpose of exercising control or management of any
    other issuer.
 
    If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage resulting from a change in values of
portfolio securities or amount of total or net assets will not be considered a
violation of any of the foregoing restrictions.
 
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objective by investing all or substantially all
of its assets in another investment company having substantially the same
investment objective and policies as the Fund.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject to the general supervision of the Board of Trustees, the Investment
Manager is responsible for decisions to buy and sell securities for the Fund,
the selection of brokers and dealers to effect the transactions, and the
negotiation of brokerage commissions, if any. Purchases and sales of securities
on a stock exchange are effected through brokers who charge a commission for
their services. In the over-the-counter market, securities are generally traded
on a "net" basis with dealers acting as principal for their own accounts without
a stated commission, although the price of the security usually includes a
profit to the dealer. The Fund expects that securities will be purchased at
times in underwritten offerings where the price includes a fixed amount of
compensation, generally referred to as the underwriter's concession or discount.
Options and futures transactions will usually be effected through a broker and a
commission will be charged. On occasion, the Fund may also purchase certain
money market instruments directly from an issuer, in which case no commissions
or discounts are paid. During the fiscal years ended July 31, 1995, 1996 and
1997, the Fund paid a total of $845,540, $1,417,865 and $1,189,162,
respectively, in brokerage commissions.
 
    The Investment Manager currently serves as investment manager to a number of
clients, including other investment companies, and may in the future act as
investment manager or adviser to others. It is the practice of the Investment
Manager to cause purchase and sale transactions to be allocated among the Fund
and others whose assets it manages in such manner as it deems equitable. In
making such allocations among the Fund and other client accounts, various
factors may be considered, including the respective investment objectives, the
relative size of portfolio holdings of the same or comparable 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 for its
portfolio is that primary consideration will be given to obtaining the most
favorable prices and efficient executions of transactions. Consistent with this
policy, when securities transactions are effected on a stock exchange, the
Fund's policy is to pay commissions which are considered fair and reasonable
without necessarily determining that the lowest possible commissions are paid in
all circumstances. The Fund believes that a requirement always to seek the
lowest possible commission cost could impede effective portfolio management and
preclude the Fund and the Investment Manager from obtaining a high quality of
brokerage and research services. In seeking to determine the reasonableness of
brokerage commissions paid in any transaction, the Investment Manager relies
upon its experience and knowledge regarding commissions generally charged by
various brokers and on its judgment in evaluating the brokerage and research
services received from the broker effecting the transaction. Such determinations
are necessarily subjective and imprecise, as in most cases an exact dollar value
for those services is not ascertainable.
 
                                       27
<PAGE>
    In seeking to implement the Fund's policies, the Investment Manager effects
transactions with those brokers and dealers who the Investment Manager believes
provide the most favorable prices and are capable of providing efficient
executions. If the Investment Manager believes such prices and executions are
obtainable from more than one broker or dealer, it may give consideration to
placing portfolio transactions with those brokers and dealers who also furnish
research and other services to the Fund or the Investment Manager. Such services
may include, but are not limited to, any one or more of the following:
information as to the availability of securities for purchase or sale;
statistical or factual information or opinions pertaining to investment; wire
services; and appraisals or evaluations of portfolio securities. During the
fiscal year ended July 31, 1997, the Fund directed the payment of $1,114,797 in
brokerage commissions in connection with transactions in the aggregate amount of
$735,355,459 to brokers because of research services provided.
 
    The information and services received by the Investment Manager from brokers
and dealers may be of benefit to the Investment Manager in the management of
accounts of some of its other clients and may not in all cases benefit the Fund
directly. While the receipt of such information and services is useful in
varying degrees and would generally reduce the amount of research or services
otherwise performed by the Investment Manager and thereby reduce its expenses,
it is of indeterminable value and the management fee paid to the Investment
Manager is not reduced by any amount that may be attributable to the value of
such services.
 
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR. The
Fund will limit such transactions with DWR to U.S. Government and Government
Agency Securities, Bank Money Instruments (i.e., Certificates of Deposit and
Bankers' Acceptances) and Commercial Paper. Such transactions will be effected
with DWR only when the price available from DWR is better than that available
from other dealers.
 
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions for the Fund,
the commissions, fees or other remuneration received by the affiliated broker or
dealer 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 the affiliated broker or
dealer 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 Board of Trustees of the Fund, including a majority of the
Trustees who are not "interested" persons of the Fund, as defined in the Act,
have adopted procedures which are reasonably designed to provide that any
commissions, fees or other remuneration paid to an affiliated broker or dealer
are consistent with the foregoing standard. The Fund does not reduce the
management fee it pays to the Investment Manager by any amount of the brokerage
commissions it may pay to an affiliated broker or dealer. During the fiscal
years ended July 31, 1995, 1996 and 1997, the Fund paid a total of $84,770,
$105,265 and $37,367, respectively, in brokerage commissions to DWR. The
brokerage commissions paid to DWR represented approximately 3.14% of the total
brokerage commissions paid by the Fund for the fiscal year ended July 31, 1997
and were paid on account of transactions having an aggregate dollar value equal
to approximately 6.68% of the aggregate dollar value of all portfolio
transactions of the Fund during the period for which commissions were paid.
During the period June 1 through July 31, 1997, the Fund paid a total of $1,005
in brokerage commissions to Morgan Stanley & Co., Inc., which broker-dealer
became an affiliate of the Investment Manager on May 31, 1997 upon consummation
of the merger of Dean Witter, Discover & Co. with Morgan Stanley Group Inc. The
brokerage commissions paid to Morgan Stanley & Co., Inc. represented
approximately 0.08% of the total brokerage commissions paid by the Fund for this
period and were paid on account of transactions having an aggregate dollar value
equal to approximately 0.10% of the aggregate dollar value of all portfolio
transactions of the Fund during the period for which commissions were paid.

    During the fiscal year ended July 31, 1997, the Fund purchased bonds issued
by Bank America, The Bank of New York, Chase Manhattan Corp., Lehman Brothers
Holdings Inc., Morgan Stanley Group Inc. and PaineWebber Inc., and common stock
issued by Chase Manhattan Corp. At July 31, 1997, the Fund held a bond issued by
Lehman Brothers Holdings Inc. and common stock issued by Chase Manhattan Corp.
with market values of $6,033,060 and $17,034,375, respectively. These issuers
were among the ten brokers or the ten dealers which executed transactions for or
with the Fund in the largest dollar amounts during the fiscal year ended July
31, 1997.
 
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 MSDWD. 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 June 30, 1997, the
current Distribution Agreement appointing the Distributor exclusive distributor
of the Fund's shares and providing for the Distributor to bear distribution
expenses not borne by the Fund. By its terms, the Distribution Agreement has an
initial term ending April 30, 1998, and will remain in effect from year to year
thereafter if approved by the 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 securities laws and pays filing fees in accordance with
state securities laws. The Fund and the Distributor have agreed to indemnify
each other against certain liabilities, including liabilities under the
Securities Act of 1933, as amended. Under the Distribution Agreement, the
Distributor uses its best efforts in rendering services to the Fund, but in the
absence of willful misfeasance, bad faith, gross negligence or reckless
disregard of its obligations, the Distributor is not liable to the Fund or any
of its shareholders for any error of judgement or mistake of law or for any act
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"), pursuant to which each Class, other than Class D, pays the
Distributor compensation accrued daily and payable monthly at the following
annual rates: 0.25% and 1.0% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, (i) 1.0% of the lesser of:
(a) the average daily aggregate gross sales of the Fund's Class B shares since
the implementation of the Plan on November 8, 1989 (not including reinvestments
of dividends or capital gains distributions), less the average daily aggregate
net asset value of the Fund's Class B shares redeemed since the implementation
of the Plan upon which a contingent deferred sales charge has been imposed or
upon which such charge has been waived, or (b) the average daily net assets of
Class B attributable to shares issued, net of related shares redeemed, since the
implementation of the Plan; plus (ii) 0.25% of the average daily net assets of
Class B attributable to shares issued, net of related shares redeemed, prior to
implementation of the Plan. The Distributor also receives the proceeds of
front-end sales charges and of contingent deferred sales charges imposed on
certain redemptions of shares, which are separate and apart from payments made
pursuant to the Plan (see "Purchase of Fund Shares" in the Prospectus). The
Distribu-
 
                                       29
<PAGE>
tor has informed the Fund that it and/or DWR received approximately $1,775,000,
$1,662,000 and $1,683,000 in contingent deferred sales charges for the fiscal
years ended July 31, 1995, 1996 and 1997, respectively, none of which was
retained by the Distributor. These amounts were received from Class B only. No
front-end sales charges were received from Class A and no contingent deferred
sales charges were received from Class A or Class C for the fiscal period July
28 through July 31, 1997.
 
    The Distributor has informed the Fund that the entire fee payable by Class A
and a portion of the fees payable by each of Class B and Class C each year
pursuant to the Plan equal to 0.25% of such Class's average daily net assets are
currently each characterized as a "service fee" under the Rules of the
Association of the National Association of Securities Dealers, Inc. (of which
the Distributor is a member). The "service fee" is a payment made for personal
service and/or the maintenance of shareholder accounts. The remaining portion of
the Plan fees payable by a Class, if any, is characterized as an "asset-based
sales charge" as such is defined by the aforementioned Rules of the Association.
 
    The Plan was adopted by a majority vote of the Trustees, including all of
the Trustees who are not "interested persons" of the Fund (as defined in the
Act) and who had or have no direct or indirect financial interest in the
operation of the Plan (the "Independent 12b-1 Trustees"), cast in person at a
meeting called for the purpose of voting on the Plan, on July 27, 1989, and by
the shareholders holding a majority, as defined in the Act, of the outstanding
shares of the Fund, at the Fund's Special Meeting of Shareholders held on
November 8, 1989. The Plan amended and restated the Fund's initial Plan of
Distribution which had been in effect from August 26, 1988 through November 7,
1989.
 
    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 an internal reorganization the share distribution activities
theretofore performed for the Fund by DWR were assumed by the Distributor and
DWR's sales activities are now being performed pursuant to the terms of a
selected dealer agreement between the Distributor and DWR. The amendments
provide that payments under the Plan will be made to the Distributor rather than
to DWR as before the amendment, and that the Distributor in turn is authorized
to make payments to DWR, its affiliates or other selected broker-dealers (or
direct that the Fund pay such entities directly). The Distributor is also
authorized to retain part of such fee as compensation for its own
distribution-related expenses. At their meeting held on April 28, 1993, the
Trustees, including a majority of the Independent 12b-1 Trustees, also approved
certain technical amendments to the Plan in connection with amendments adopted
by the National Association of Securities Dealers, Inc. to its Rules of the
Association. At their meeting held on December 19, 1995, the shareholders of the
Fund approved an amendment to the Plan to permit payments to be made under the
Plan with respect to distribution expenses incurred in connection with the
distribution of shares of an investment company whose assets are acquired by the
Fund in a tax-free reorganization. At their meeting held on June 30, 1997, the
Trustees, including a majority of the Independent 12b-1 Trustees, approved
amendments to the Plan to reflect the multiple-class structure for the Fund,
which took effect on July 28, 1997.
 
    Under the Plan and as required by Rule 12b-1, the Trustees receive and
review promptly after the end of each fiscal quarter a written report provided
by the Distributor of the amounts expended by the Distributor under the Plan and
the purpose for which such expenditures were made. Class B shares of the Fund
accrued amounts payable to the Distributor under the Plan, during the fiscal
year ended July 31, 1997, of $12,491,604. This amount is equal to 0.89% of the
average daily net assets of Class B for the fiscal year and was calculated
pursuant to clauses (i)(a) and (ii) of the compensation formula under the Plan.
This amount is treated by the Fund as an expense in the year it is accrued. For
the fiscal period July 28 through July 31, 1997, Class A and Class C shares of
the Fund accrued payments under the Plan amounting to $1 and $6, respectively,
which amounts are equal to 0.25% and 1.0% of the average daily net assets of
Class A and Class C, respectively, for such period.
 
    The Plan was adopted in order to permit the implementation of the Fund's
method of distribution. Under this distribution method the Fund offers four
Classes of shares, each with a different distribution arrangement as set forth
in the Prospectus.
 
                                       30
<PAGE>
    With respect to Class A shares, DWR compensates its account executives by
paying them, from proceeds of the front-end sales charge, commissions for the
sale of Class A shares, currently a gross sales credit of up to 5.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.25% of the current value of
the respective accounts for which they are the account executives or dealers of
record in all cases. On orders of $1 million or more (for which no sales charge
was paid) or net asset value purchases by 401(k) plans or other
employer-sponsored plans qualified under Section 401(a) of the Internal Revenue
Code for which Dean Witter Trust FSB ("DWT") serves as Trustee or the 401(k)
Support Services Group of DWR serves as recordkeeper, the Investment Manager
compensates DWR's account executives by paying them, from its own funds, a gross
sales credit of 1.0% of the amount sold.
 
    With respect to Class B shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class B shares,
currently a gross sales credit of up to 5.0% of the amount sold (except as
provided in the following sentence) and an annual residual commission, currently
a residual of up to 0.25% of the current value (not including reinvested
dividends or distributions) of the amount sold in all cases. In the case of
retirement plans qualified under Section 401(k) of the Internal Revenue Code and
other employer-sponsored plans qualified under Section 401(a) of the Internal
Revenue Code for which DWT serves as Trustee or the 401(k) Support Services
Group of DWR serves as recordkeeper, and which plans are opened on or after July
28, 1997, DWR compensates its account executives by paying them, from its own
funds, a gross sales credit of 3.0% of the amount sold.
 
    With respect to Class C shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class C shares,
currently a gross sales credit of up to 1.0% of the amount sold and an annual
residual commission, currently a residual of up to 1.0% of the current value of
the respective accounts for which they are the account executives of record.
 
    With respect to Class D shares other than shares held by participants in
InterCapital's mutual fund asset allocation program, the Investment Manager
compensates DWR's account executives by paying them, from its own funds,
commissions for the sale of Class D shares, currently a gross sales credit of up
to 1.0% of the amount sold. There is a chargeback of 100% of the amount paid if
the Class D shares are redeemed in the first year and a chargeback of 50% of the
amount paid if the Class D shares are redeemed in the second year after
purchase. The Investment Manager also compensates DWR's account executives by
paying them, from its own funds, an annual residual commission, currently a
residual of up to 0.10% of the current value of the respective accounts for
which they are the account executives of record (not including accounts of
participants in the InterCapital mutual fund asset allocation program).
 
    The gross sales credit is a charge which reflects commissions paid by DWR to
its account executives and DWR's Fund associated distribution-related expenses,
including sales compensation, and overhead and other branch office
distribution-related expenses including: (a) the expenses of operating DWR's
branch offices in connection with the sale of Fund shares, including lease
costs, the salaries and employee benefits of operations and sales support
personnel, utility costs, communications costs and the costs of stationery and
supplies, (b) the costs of client sales seminars, (c) travel expenses of mutual
fund sales coordinators to promote the sale of Fund shares and (d) other
expenses relating to branch promotion of Fund share sales. The distribution fee
that the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred on behalf of the Fund and, in the case of Class B
shares, opportunity costs, such as the gross sales credit and an assumed
interest charge thereon ("carrying charge"). In the Distributor's reporting of
the distribution expenses to the Fund, in the case of Class B shares, such
assumed interest (computed at the "broker's call rate") has been calculated on
the gross sales credit as it is reduced by amounts received by the Distributor
under the Plan and any contingent deferred sales charges received by the
Distributor upon redemption of shares of the Fund. No other interest charge is
included as a distribution expense in the Distributor's calculation of
distribution costs for this purpose. The broker's call rate is the interest rate
charged to securities brokers on loans secured by exchange-listed securities.
 
                                       31
<PAGE>
    The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement will be made through payments at
the end of each month. The amount of each monthly payment may in no event exceed
an amount equal to a payment at the annual rate of 0.25%, in the case of Class
A, and 1.0%, in the case of Class C, of the average net assets of the respective
Class during the month. No interest or other financing charges, if any, incurred
on any distribution expenses on behalf of Class A and Class C will be
reimbursable under the Plan. With respect to Class A, in the case of all
expenses other than expenses representing the service fee, and, with respect to
Class C, in the case of all expenses other than expenses representing a gross
sales credit or a residual to account executives, such amounts shall be
determined at the beginning of each calendar quarter by the Trustees, including
a majority of the Independent 12b-1 Trustees. Expenses representing the service
fee (for Class A) or a gross sales credit or a residual to account executives
(for Class C) may be reimbursed without prior determination. In the event that
the Distributor proposes that monies shall be reimbursed for other than such
expenses, then in making quarterly determinations of the amounts that may be
reimbursed by the Fund, the Distributor will provide and the Trustees will
review a quarterly budget of projected distribution expenses to be incurred on
behalf of the Fund, together with a report explaining the purposes and
anticipated benefits of incurring such expenses. The Trustees will determine
which particular expenses, and the portions thereof, that may be borne by the
Fund, and in making such a determination shall consider the scope of the
Distributor's commitment to promoting the distribution of the Fund's Class A and
Class C shares.
 
    Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended July 31, 1997 to the Distributor. The
Distributor and DWR estimate that they have spent, pursuant to the Plan,
$91,860,398 on behalf of Class B since the inception of the Fund. It is
estimated that this amount was spent in approximately the following ways: (i)
3.25% ($2,989,043)--advertising and promotional expenses; (ii) 0.29% ($270,696)
printing of prospectuses for distribution to other than current shareholders;
and (iii) 96.46% ($88,600,659)--other expenses, including the gross sales credit
and the carrying charge, of which 7.64% ($6,770,173) represents carrying
charges, 30.83% ($27,313,322) represents commission credits to DWR branch
offices for payments of commissions to account executives, 46.36% ($41,072,562)
represents overhead and other branch office distribution-related expenses, and
15.17% ($13,444,602) represents excess distribution expenses of Dean Witter
Managed Assets Trust, the net assets of which were combined with those of the
Fund on December 22, 1995 pursuant to an Agreement and Plan of Reorganization.
The amounts accrued by Class A and Class C for distribution during the fiscal
period July 28 through July 31, 1997 were for expenses which relate to
compensation of sales personnel and associated overhead expenses.
 
    In the case of Class B shares, at any given time, the expenses in
distributing shares of the Fund may be more or less than the total of (i) the
payments made by the Fund pursuant to the Plan and (ii) the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares.
The Distributor has advised the Fund that in the case of Class B shares the
excess distribution expenses, including the carrying charge designed to
approximate the opportunity costs incurred by DWR which arise from it having
advanced monies without having received the amount of any sales charges imposed
at the time of sale of the Fund's Class B shares, totalled $37,067,710 as of
July 31, 1997. Because there is no requirement under the Plan that the
Distributor be reimbursed for all expenses with respect to Class B shares or any
requirement that the Plan be continued from year to year, this excess amount
does not constitute a liability of the Fund. Although there is no legal
obligation for the Fund to pay distribution expenses in excess of payments made
to the Distributor under the Plan and the proceeds of contingent deferred sales
charges paid by investors upon redemption of shares, if for any reason the Plan
is terminated, the Trustees will consider at that time the manner in which to
treat such expenses. Any cumulative expenses incurred, but not yet recovered
through distribution fees or contingent deferred sales charges, may or may not
be recovered through future distribution fees or contingent deferred sales
charges.
 
    No interested person of the Fund or 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
 
                                       32
<PAGE>
to the extent that the Distributor, InterCapital, DWR, DWSC or certain of their
employees may be deemed to have such interest as a result of benefits derived
from the successful operation of the Plan or as a result of receiving a portion
of the amounts expended thereunder by the Fund.
 
    Under its terms, the Plan had an initial term ending April 30, 1990 and will
continue from year to year thereafter, provided such continuance is approved
annually by a vote of the Trustees in the manner described above. Prior to the
Board's approval of amendments to the Plan to reflect the multiple-class
structure for the Fund, the most recent continuance of the Plan for one year,
until April 30, 1998, was approved by the Trustees of the Fund, including a
majority of the Independent 12b-1 Trustees, at a meeting of the Trustees held on
April 24, 1997. Prior to approving the continuation of the Plan, the Trustees
requested and received from the Distributor and reviewed all 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 therein.
 
    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval of the shareholders of the
affected Class or Classes of the Fund, and all material amendments of the Plan
must also be approved by the Trustees in the manner described above. The Plan
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Trustees who are not interested persons of the Fund and who have
no direct or indirect financial interest in the operation of the Plan, or by a
vote of a majority of the outstanding voting securities of the Fund (as defined
in the Act) on not more than thirty days' written notice to any other party to
the Plan. So long as the Plan is in effect, the election and nomination of
Independent 12b-1 Trustees shall be committed to the discretion of the
Independent 12b-1 Trustees.
 
DETERMINATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------
 
    As stated in the Prospectus, short-term 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 on debt securities 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 on debt
securities and all options on equity securities 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 for each Class of shares of the Fund is
determined once daily at 4:00 p.m. New York time (or, on days when the New York
Stock Exchange closes prior to 4:00 p.m., at such earlier time), on each day
that the New York Stock Exchange is open. The New York Stock Exchange
 
                                       33
<PAGE>
currently observes the following holidays: New Year's Day, Reverend Dr. Martin
Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day, and Christmas Day.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund offers four Classes of shares as
follows:
 
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
 
    Class A shares are sold to investors with an initial sales charge that
declines to zero for larger purchases; however, Class A shares sold without an
initial sales charge are subject to a contingent deferred sales charge ("CDSC")
of 1.0% if redeemed within one year of purchase, except in the circumstances
discussed in the Prospectus.
 
    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 $25,000 in net asset value. For
example, if any person or entity who qualifies for this privilege holds Class A
shares of the Fund and/or other Dean Witter Funds that are multiple class funds
("Dean Witter Multi-Class Funds") or shares of other Dean Witter Funds sold with
a front-end sales charge purchased at a price including a front-end sales charge
having a current value of $5,000, and purchases $20,000 of additional shares of
the Fund, the sales charge applicable to the $20,000 purchase would be 4.75% of
the offering price.
 
    The Distributor must be notified by the selected broker-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 selected broker-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 FSB (the "Transfer Agent")
fails to confirm the investor's represented holdings.
 
    LETTER OF INTENT.  As discussed in the Prospectus, 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 Class A shares of the Fund from
the Distributor or from a single Selected Broker-Dealer.
 
    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 of Class A shares 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.
For the purpose of determining whether the investor is entitled to a further
reduced sales charge applicable to purchases at or above a sales charge level
which exceeds the stated goal of a Letter of Intent, the cumulative current net
asset value of any shares owned by the investor in any other Dean Witter Funds
held by the shareholder which were previously purchased at a price including a
front-end sales charge
 
                                       34
<PAGE>
(including shares of the Fund and other Dean Witter Funds acquired in exchange
for those shares, and including in each case shares acquired through
reinvestment of dividends and distributions) will be added to the cost or net
asset value of shares of the Fund owned by the investor. However, shares of
"Exchange Funds" (see "Shareholder Services--Exchange Privilege") and the
purchase of shares of other Dean Witter Funds will not be included in
determining whether the stated goal of a Letter of Intent has been reached.
 
    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.
 
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES
 
    Class B shares are sold without an initial sales charge but are subject to a
CDSC payable upon most redemptions within six years after purchase. As stated in
the Prospectus, a CDSC will be imposed on any redemption by an investor if after
such redemption the current value of the investor's Class B shares of the Fund
is less than the dollar amount of all payments by the shareholder for the
purchase of Class B shares during the preceding six years (or, in the case of
shares held by certain employer-sponsored benefit plans, three years). However,
no CDSC will be imposed to the extent that the net asset value of the shares
redeemed does not exceed: (a) the current net asset value of shares purchased
more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption, plus (b)
the current net asset value of shares purchased through reinvestment of
dividends or distributions of the Fund or another Dean Witter Fund (see
"Shareholder Services-- Targeted Dividends"), plus (c) the current net asset
value of shares acquired in exchange for (i) shares of Dean Witter front-end
sales charge funds, or (ii) shares of other Dean Witter Funds for which shares
of front-end sales charge funds have been exchanged (see "Shareholder
Services--Exchange Privilege"), plus (d) increases in the net asset value of the
investor's shares above the total amount of payments for the purchase of Fund
shares made during the preceding six (three) years. The CDSC will be paid to the
Distributor.
 
    In determining the applicability of the CDSC to each redemption, the amount
which represents an increase in the net asset value of the investor's shares
above the amount of the total payments for the purchase of shares within the
last six years (or, in the case of shares held by certain employer-sponsored
benefit plans, three years) will be redeemed first. In the event the redemption
amount exceeds such increase in value, the next portion of the amount redeemed
will be the amount which represents the net asset value of the investor's shares
purchased more than six (three) years prior to the redemption and/or shares
purchased through reinvestment of dividends or distributions and/or shares
acquired in exchange for shares of Dean Witter front-end sales charge funds, or
for shares of other Dean Witter funds for which shares of front-end sales charge
funds have been exchanged. A portion of the amount redeemed which exceeds an
amount which represents both such increase in value and the value of shares
purchased more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption and/or
shares purchased through reinvestment of dividends or distributions and/or
shares acquired in the above-described exchanges will be subject to a CDSC.
 
    The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of Class B shares of the Fund until
the time of redemption of such shares. For purposes of determining the number of
years from the time of any payment for the purchase of shares,
 
                                       35
<PAGE>
all payments made during a month will be aggregated and deemed to have been made
on the last day of the month. The following table sets forth the rates of the
CDSC applicable to most Class B shares of the Fund:

    The following table sets forth the rates of the CDSC applicable to Class B

</TABLE>
 
    In determining the rate of the CDSC, it will be assumed that a redemption is
made of shares held by the investor for the longest period of time within the
applicable six-year or three-year period. This will result in any such CDSC
being imposed at the lowest possible rate. The CDSC will be imposed, in
accordance with the table shown above, on any redemptions within six years (or,
in the case of shares held by certain employer-sponsored benefit plans, three
years) of purchase which are in excess of these amounts and which redemptions do
not qualify for waiver of the CDSC, as described in the Prospectus.
 
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
 
    Class C shares are sold without a sales charge but are subject to a CDSC of
1.0% on most redemptions made within one year after purchase, except in the
circumstances discussed in the Prospectus.
 
NO LOAD ALTERNATIVE--CLASS D SHARES
 
    Class D shares are offered without any sales charge on purchase or
redemption. Class D shares are offered only to those persons meeting the
qualifications set forth in the Prospectus.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened for the investor on the books of the Fund and maintained by the Transfer
Agent. This is an open account in which shares owned by the investor are
credited by the Transfer Agent in lieu of issuance of a share certificate. If a
share certificate is desired, it must be requested in writing for each
transaction. Certificates are issued only for full shares and may be redeposited
in the account at any time. There is no charge to the investor for issuance of a
certificate. Whenever a shareholder-instituted transaction takes place in the
Shareholder Investment Account, the shareholder will be mailed a confirmation of
the transaction from the Fund or from DWR or other selected broker-dealer.
 
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  As stated in the
Prospectus, all income dividends and capital gains distributions are
automatically paid in full and fractional shares of the
 
                                       36
<PAGE>
applicable Class of the Fund, unless the shareholder requests that they be paid
in cash. Each purchase of shares of the Fund is made upon the condition that the
Transfer Agent is thereby automatically appointed as agent of the investor to
receive all dividends and capital gains distributions on shares owned by the
investor. Such dividends and distributions will be paid, at the net asset value
per share, in shares of the applicable Class of the Fund (or in cash if the
shareholder so requests) as of the close of business on the record date. At any
time an investor may request the Transfer Agent, in writing, to have subsequent
dividends and/or capital gains distributions paid to him or her in cash rather
than shares. To assure sufficient time to process the change, such request
should be received by the Transfer Agent at least five business days prior to
the record date of the dividend or distribution. In the case of recently
purchased shares for which registration instructions have not been received on
the record date, cash payments will be made to DWR or the other selected
broker-dealer, and will be forwarded to the shareholder, upon the receipt of
proper instructions. It has been and remains the Fund's policy and practice
that, if checks for dividends or distributions paid in cash remain uncashed, no
interest will accrue on amounts represented by such uncashed checks.
 
    TARGETED DIVIDENDS.-SM-  In states where it is legally permissible,
shareholders may also have all income dividends and capital gains distributions
automatically invested in shares of any Class of an open-end Dean Witter Fund
other than Dean Witter Strategist Fund or in another Class of Dean Witter
Strategist Fund. Such investment will be made as described above for automatic
investment in shares of the applicable Class of the Fund, at the net asset value
per share of the selected Dean Witter Fund as of the close of business on the
payment date of the dividend or distribution and will begin to earn dividends,
if any, in the selected Dean Witter Fund the next business day. To participate
in the Targeted Dividends program, shareholders should contact their DWR or
other selected broker-dealer account executive or the Transfer Agent.
Shareholders of the Fund must be shareholders of the selected Class of the Dean
Witter Fund targeted to receive investments from dividends at the time they
enter the Targeted Dividends program. Investors should review the prospectus of
the targeted Dean Witter Fund before entering the program.
 
    EASYINVEST.-SM-  Shareholders may subscribe to EasyInvest, an automatic
purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account or following
redemption of shares of a Dean Witter money market fund, on a semi-monthly,
monthly or quarterly basis, to the Transfer Agent for investment in shares of
the Fund. Shares purchased through EasyInvest will be added to the shareholder's
existing account at the net asset value calculated the same business day the
transfer of funds is effected (subject to any applicable sales charges). For
further information or to subscribe to EasyInvest, shareholders should contact
their DWR or other selected broker-dealer account executive or the Transfer
Agent.
 
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  As discussed in
the Prospectus, any shareholder who receives a cash payment representing a
dividend or capital gains distribution may invest such dividend or distribution
in shares of the applicable Class at net asset value, without the imposition of
a CDSC upon redemption, by returning the check or the proceeds to the Transfer
Agent within thirty days after the payment date. If the shareholder returns the
proceeds of a dividend or distribution, such funds must be accompanied by a
signed statement indicating that the proceeds constitute a dividend or
distribution to be invested. Such investment will be made at the net asset value
per share next determined after receipt of the check or the proceeds by the
Transfer Agent.
 
    SYSTEMATIC WITHDRAWAL PLAN.  As discussed in the Prospectus, a systematic
withdrawal plan (the "Withdrawal Plan") is available for shareholders who own or
purchase shares of the Fund having a minimum value of $10,000 based upon the
then current net asset value. The Withdrawal Plan provides for monthly or
quarterly (March, June, September and December) checks in any dollar amount, not
less than $25, or in any whole percentage of the account balance, on an
annualized basis. Any applicable CDSC will be imposed on shares redeemed under
the Withdrawal Plan (see "Purchase of Fund Shares"). Therefore, any shareholder
participating in the Withdrawal Plan will have sufficient shares redeemed from
his or her account so that the proceeds (net of any applicable CDSC) to the
shareholder will be the designated monthly or quarterly amount.
 
                                       37
<PAGE>
    The Transfer Agent acts as agent for the shareholder in tendering to the
Fund for redemption sufficient full and fractional shares to provide the amount
of the periodic withdrawal payment designated in the application. The shares
will be redeemed at their net asset value determined, at the shareholder's
option, on the tenth or twenty-fifth day (or next following business day) of the
relevant month or quarter and normally a check for the proceeds will be mailed
by the Transfer Agent, or amounts credited to a shareholder's DWR or other
selected broker-dealer brokerage account, within five business days after the
date of redemption. The Withdrawal Plan may be terminated at any time by the
Fund.
 
    Withdrawal Plan payments should not be considered as dividends, yields or
income. If periodic withdrawal plan payments continuously exceed net investment
income and net capital gains, the shareholder's original investment will be
correspondingly reduced and ultimately exhausted.
 
    Each withdrawal constitutes a redemption of shares and any gain or loss
realized must be recognized for federal income tax purposes. Although the
shareholder may make additional investments of $2,500 or more under the
Withdrawal Plan, withdrawals made concurrently with purchases of additional
shares may be inadvisable because of sales charges which may be applicable to
purchases or redemptions of shares (see "Purchase of Fund 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 INVESTMENT THROUGH TRANSFER AGENT.  As discussed in the Prospectus, a
shareholder may make additional investments in any Class of shares of the Fund
for which they qualify at any time by sending a check in any amount, not less
than $100, payable to Dean Witter Strategist Fund, and indicating the selected
Class, directly to the Fund's Transfer Agent. In the case of Class A shares,
after deduction of any applicable sales charge, the balance will be applied to
the purchase of Fund shares, and, in the case of shares of the other Classes,
the entire amount 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 each Class of shares of the Fund
may exchange their shares for shares of the same Class of shares of any other
Dean Witter Multi-Class Fund without the imposition of any exchange fee. Shares
may also be exchanged for shares of any of the following funds: Dean Witter
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury Trust
and five Dean Witter Funds which are money market funds (the foregoing nine
funds are hereinafter referred to as the "Exchange Funds"). Class A shares may
also be exchanged for shares of Dean Witter Multi-State Municipal Series Trust
and Dean Witter Hawaii Municipal Trust, which are Dean Witter Funds sold with a
front-end sales charge ("FSC Funds"). Class B shares may also be exchanged for
shares of Dean Witter Global Short-Term Income Fund Inc., Dean Witter High
Income Securities and Dean Witter National Municipal Trust, which are Dean
Witter Funds offered with a CDSC ("CDSC 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.
 
                                       38
<PAGE>
There is no waiting period for exchanges of shares acquired by exchange or
dividend reinvestment. An exchange will be treated for federal income tax
purposes the same as a repurchase or redemption of shares, on which the
shareholder may realize a capital gain or loss.
 
    Any new account established through the Exchange Privilege will have the
same registration and cash dividend or dividend reinvestment plan as the present
account, unless the Transfer Agent receives written notification to the
contrary. For telephone exchanges, the exact registration of the existing
account and the account number must be provided.
 
    Any shares held in certificate form cannot be exchanged but must be
forwarded to the Transfer Agent and deposited into the shareholder's account
before being eligible for exchange. (Certificates mailed in for deposit should
not be endorsed.)
 
    As described below, and in the Prospectus under the caption "Purchase of
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number of
factors, including the number of years from the time of purchase until the time
of redemption or exchange ("holding period"). When shares of a Dean Witter
Multi-Class Fund or any CDSC Fund are exchanged for shares of an Exchange Fund,
the exchange is executed at no charge to the shareholder, without the imposition
of the CDSC at the time of the exchange. During the period of time the
shareholder remains in the Exchange Fund (calculated from the last day of the
month in which the Exchange Fund shares were acquired), the holding period or
"year since purchase payment made" is frozen. When shares are redeemed out of
the Exchange Fund, they will be subject to a CDSC which would be based upon the
period of time the shareholder held shares in a Dean Witter Multi-Class Fund or
in a CDSC Fund. However, in the case of shares exchanged into an Exchange Fund
on or after April 23, 1990, upon a redemption of shares which results in a CDSC
being imposed, a credit (not to exceed the amount of the CDSC) will be given in
an amount equal to the Exchange Fund 12b-1 distribution fees, if any, incurred
on or after that date which are attributable to those shares. Shareholders
acquiring shares of an Exchange Fund pursuant to this exchange privilege may
exchange those shares back into a Dean Witter Multi-Class Fund or a CDSC Fund
from the Exchange Fund, with no CDSC being imposed on such exchange. The holding
period previously frozen when shares were first exchanged for shares of the
Exchange Fund resumes on the last day of the month in which shares of a Dean
Witter Multi-Class Fund or of a CDSC Fund are reacquired. A CDSC is imposed only
upon an ultimate redemption, based upon the time (calculated as described above)
the shareholder was invested in a Dean Witter Multi-Class Fund or in a CDSC
Fund. In the case of exchanges of Class A shares which are subject to a CDSC,
the holding period also includes the time (calculated as described above) the
shareholder was invested in a FSC Fund.
 
    When shares initially purchased in a Dean Witter Multi-Class Fund or in a
CDSC Fund are exchanged for shares of a Dean Witter Multi-Class Fund, shares of
a CDSC Fund, shares of a FSC Fund, or shares of an Exchange Fund, the date of
purchase of the shares of the fund exchanged into, for purposes of the CDSC upon
redemption, will be the last day of the month in which the shares being
exchanged were originally purchased. In allocating the purchase payments between
funds for purposes of the CDSC, the amount which represents the current net
asset value of shares at the time of the exchange which were (i) purchased more
than one, three or six years (depending on the CDSC schedule applicable to the
shares) prior to the exchange, (ii) originally acquired through reinvestment of
dividends or distributions and (iii) acquired in exchange for shares of FSC
Funds, or for shares of other Dean Witter Funds for which shares of FSC Funds
have been exchanged (all such shares called "Free Shares"), will be exchanged
first. After an exchange, all dividends earned on shares in an Exchange Fund
will be considered Free Shares. If the exchanged amount exceeds the value of
such Free Shares, an exchange is made, on a block-by-block basis, of non-Free
Shares held for the longest period of time (except that, with respect to Class B
shares, if shares held for identical periods of time but subject to different
CDSC schedules are held in the same Exchange Privilege account, the shares of
that block that are subject to a lower CDSC rate will be exchanged prior to the
shares of that block that are subject to a higher CDSC rate). Shares equal to
any appreciation in the value of non-Free Shares exchanged will be treated as
Free Shares, and the amount of the purchase payments for the non-Free Shares of
the fund exchanged into will be equal to the lesser of (a) the purchase payments
for, or (b) the current net asset
 
                                       39
<PAGE>
value of, the exchanged non-Free Shares. If an exchange between funds would
result in exchange of only part of a particular block of non-Free Shares, then
shares equal to any appreciation in the value of the block (up to the amount of
the exchange) will be treated as Free Shares and exchanged first, and the
purchase payment for that block will be allocated on a pro rata basis between
the non-Free Shares of that block to be retained and the non-Free Shares to be
exchanged. The prorated amount of such purchase payment attributable to the
retained non-Free Shares will remain as the purchase payment for such shares,
and the amount of purchase payment for the exchanged non-Free Shares will be
equal to the lesser of (a) the prorated amount of the purchase payment for, or
(b) the current net asset value of, those exchanged non-Free Shares. Based upon
the procedures described in the Prospectus under the caption "Purchase of Fund
Shares," any applicable CDSC will be imposed upon the ultimate redemption of
shares of any fund, regardless of the number of exchanges since those shares
were originally purchased.
 
    With respect to the redemption or repurchase of shares of the Fund, the
application of proceeds to the purchase of new shares in the Fund or any other
of the funds and the general administration of the 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. With
respect to exchanges, redemptions or repurchases, the Transfer Agent shall be
liable for its own negligence and not for the default or negligence of its
correspondents or for losses in transit. The Fund shall not be liable for any
default or negligence of the Transfer Agent, the Distributor or any selected
broker-dealer.
 
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any selected broker-dealer for any
transactions pursuant to this Exchange Privilege.
 
    Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class 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 the Exchange Privilege
account of each Class is $10,000 for Dean Witter Short-Term U.S. Treasury Trust
although that fund may, in its discretion, accept initial investments as low as
$5,000. The minimum initial investment for the Exchange Privilege account of
each Class is $5,000 for Dean Witter Special Value Fund. The minimum initial
investment for the Exchange Privilege account of each Class of 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
Exchange Funds pursuant to the Exchange Privilege, and provided further that the
Exchange Privilege may be terminated or materially revised without notice at
times (a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on that Exchange is re-
stricted, (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
 
                                       40
<PAGE>
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.
 
    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
- --------------------------------------------------------------------------------
 
    REDEMPTION.  As stated in the Prospectus, shares of each Class of the Fund
can be redeemed for cash at any time at the net asset value per share next
determined; however, such redemption proceeds will be reduced by the amount of
any applicable CDSC. If shares are held in a shareholder's account without a
share certificate, a written request for redemption to the Fund's Transfer Agent
at P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by
the shareholder, the shares may be redeemed by surrendering the certificates
with a written request for redemption. The share certificate, or an accompanying
stock power, and the request for redemption, must be signed by the shareholder
or shareholders exactly as the shares are registered. Each request for
redemption, whether or not accompanied by a share certificate, must be sent to
the Fund's Transfer Agent, which will redeem the shares at their net asset value
next computed (see "Purchase of Fund Shares") after it receives the request, and
certificate, if any, in good order. Any redemption request received after such
computation will be redeemed at the next determined net asset value.
 
    Whether certificates are held by the shareholder or shares are held in a
shareholder's account, if the proceeds are to be paid to any person other than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership, trust or fiduciary, or sent to the shareholder at an address other
than the registered address, signatures must be guaranteed by an eligible
guarantor acceptable to the Transfer Agent (shareholders should contact the
Transfer Agent for a determination as to whether a particular institution is
such an eligible guarantor). A stock power may be obtained from any dealer or
commercial bank. The Fund may change the signature guarantee requirements from
time to time upon notice to shareholders, which may be by means of a new
prospectus.
 
    REPURCHASE.  As stated in the Prospectus, DWR and other selected
broker-dealers are authorized to repurchase shares represented by a share
certificate which is delivered to any of their offices. Shares held in a
shareholder's account without a share certificate may also be repurchased by DWR
and other selected broker-dealers upon the telephonic request of the
shareholder. The repurchase price is the net asset value next computed after
such purchase order is received by DWR or other selected broker-dealer reduced
by any applicable CDSC.
 
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment for shares of any Class presented for repurchase or redemption will be
made by check within seven days after receipt by the Transfer Agent of the
certificate and/or written request in good order. The term good order means that
the share certificate, if any, and request for redemption are properly signed,
accompanied by any documentation required by the Transfer Agent, and bear
signature guarantees when required by the Fund or the Transfer Agent. Such
payment may be postponed or the right of redemption suspended at times (a) when
the New York Stock Exchange is closed for other than customary weekends and
holidays, (b) when trading on that Exchange is restricted, (c) when an emergency
exists as a result of which disposal by the Fund of securities owned by it is
not reasonably practicable or it is not reasonably practicable for the Fund
fairly to determine the value of its net assets, or (d) during any other period
when the Securities and Exchange Commission by order so permits; provided that
applicable rules and regulations of the Securities and Exchange Commission shall
govern as to whether the conditions prescribed in (b) or (c) exist. If the
shares to be redeemed have recently been purchased by check, payment of the
redemption proceeds may be delayed for the minimum time needed to verify that
the check used for investment has been honored (not more than fifteen days from
the time of receipt of
 
                                       41
<PAGE>
the check by the Transfer Agent). It has been and remains the Fund's policy and
practice that, if checks for redemption proceeds remain uncashed, no interest
will accrue on amounts represented by such uncashed checks. 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.
 
    TRANSFERS OF SHARES.  In the event a shareholder requests a transfer of any
shares to a new registration, such shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to the CDSC or free of such charge (and with regard to the length
of time shares subject to the charge have been held), any transfer involving
less than all the shares in an account will be made on a pro rata basis (that
is, by transferring shares in the same proportion that the transferred shares
bear to the total shares in the account immediately prior to the transfer). The
transferred shares will continue to be subject to any applicable CDSC as if they
had not been so transferred.
 
    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder who
has had his or her shares redeemed or repurchased and has not previously
exercised this reinstatement privilege may, within 35 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 in the same Class at the net
asset value next determined after a reinstatement request, together with the
proceeds, is received by the Transfer Agent.
 
    Exercise of the reinstatement privilege will not affect the federal income
tax 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.
 
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
net capital gains to shareholders and otherwise continue to qualify as a
regulated investment company under Subchapter M of the Internal Revenue Code, it
is not expected that the Fund will be required to pay any federal income tax.
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 net short-term capital gains, are taxable to the
shareholder as ordinary income regardless of whether the shareholder receives
such payments in additional shares or in cash. Any dividends declared in the
last quarter of any calendar year which are paid in the following year prior to
February 1 will be deemed received by the shareholder in the prior calendar
year.
 
    Gains or losses on sales of securities by the Fund 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.
 
    Gains or losses on the Fund's transactions, if any, in futures and
non-equity options generally are treated as 60% long-term and 40% short-term
capital gains or losses. When the Fund engages in futures transactions, various
tax regulations applicable to the Fund may have the effect of causing the Fund
to recognize a gain or loss for tax purposes before that gain or loss is
realized, or to defer recognition of a realized loss for tax purposes.
Recognition, for tax purposes, of an unrealized loss may result in a lesser
amount of the Fund's realized net gains being available for distribution.
 
                                       42
<PAGE>
    One of the requirements for the Fund to remain qualified as a regulated
investment company is that less than 30% of its gross income be derived from
gains from the sale or other disposition of securities held for less than three
months. Accordingly, the Fund may be restricted in the writing of options on
securities held for less than three months, in the writing of options which
expire in less than three months, and in effecting closing transactions with
respect to call or put options which have been written or purchased less than
three months prior to such transactions. The Fund may also be restricted in its
ability to engage in transactions involving futures contracts.
 
    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.
 
    Under current federal law, the Fund will receive net investment income in
the form of interest by virtue of holding Treasury bills, notes and bonds, and
will recognize income attributable to it from holding zero coupon Treasury
securities. Current federal tax law requires that a holder (such as the Fund) of
a zero coupon security accrue a portion of the discount at which the security
was purchased as income each year even though the Fund receives no interest
payment in cash on the security during the year. As an investment company, the
Fund must pay out substantially all of its net investment income each year.
Accordingly, the Fund, to the extent it invests in zero coupon Treasury
securities, may be required to pay out as an income distribution each year an
amount which is greater than the total amount of cash receipts of interest the
Fund actually received. Such distributions will be made from the available cash
of the Fund or by liquidation of portfolio securities if necessary. If a
distribution or cash necessitates the liquidation of portfolio securities, the
Investment Manager will select which securities to sell. The Fund may realize a
gain or loss from such sales. In the event the Fund realizes net capital gains
from such transactions, its shareholders may receive a larger capital gain
distribution, if any, than they would in the absence of such transactions.
 
    In computing net investment income, the Fund will not amortize premiums or
accrue discounts on fixed-income securities in the portfolio, except those
original issue discounts for which amortization is required for federal income
tax purposes. Additionally, with respect to market discounts on bonds, a portion
of any capital gain realized upon disposition may be characterized as taxable
ordinary income in accordance with the provisions of the Internal Revenue Code.
Realized gains and losses on security transactions are determined on the
identified cost method.
 
    Any dividend or capital gains distribution received by a shareholder from
any investment company will have the effect of reducing the net asset value of
the shareholder's stock in that company by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions and
dividends are subject to federal income taxes. If the net asset value of the
shares should be reduced below a shareholder's cost as a result of the payment
of dividends or the distribution of realized net long-term capital gains, such
payment or distribution would be in part a return of the shareholder's
investment to the extent of such reduction below the shareholder's cost, but
nonetheless would be fully taxable. Therefore, an investor should consider the
tax implications of purchasing Fund shares immediately prior to a distribution
record date.
 
    Dividend payments will be eligible for the federal dividends received
deduction available to the Fund's corporate shareholders only to the extent the
aggregate dividends received by the Fund would be eligible for the deduction if
the Fund were the shareholder claiming the dividends received deduction. The
amount of dividends paid by the Fund which may qualify for the dividends
received deduction is limited to the aggregate amount of qualifying dividends
which the Fund derives from its portfolio investments which the Fund has held
for a minimum period, usually 46 days. Any distributions made by the Fund will
not be eligible for the dividends received deduction with respect to shares
which are held by the shareholder for 45 days or less. Any long-term capital
gain distributions will also not be eligible for
 
                                       43
<PAGE>
the dividends received deduction. The ability to take the dividends received
deduction will also be limited in the case of a Fund shareholder which incurs or
continues indebtedness which is directly attributable to its investment in the
Fund.
 
    After the end of the year, shareholders will be sent full information on
their dividends and capital gains distributions for tax purposes, including
information as to the portion taxable as ordinary income, the portion taxable as
long-term capital gains and the portion eligible for the dividends received
deduction. To avoid being subject to a 31% federal backup withholding tax on
taxable dividends, capital gains distributions and the proceeds of redemptions
and repurchases, shareholders' taxpayer identification numbers must be furnished
and certified as to their accuracy.
 
    Shareholders are urged to consult their attorneys or tax advisers regarding
specific questions as to federal, state or local taxes.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, from time to time the Fund may quote its
"total return" in advertisements and sales literature. These figures are
computed separately for Class A, Class B, Class C and Class D shares. The Fund's
"average annual total return" represents an annualization of the Fund's total
return over a particular period and is computed by finding the annual percentage
rate which will result in the ending redeemable value of a hypothetical $1,000
investment made at the beginning of a one, five or ten year period, or for the
period from the date of commencement of the Fund's operations, if shorter than
any of the foregoing. The ending redeemable value is reduced by any CDSC at the
end of the one, five or ten year or other period. For the purpose of this
calculation, it is assumed that all dividends and distributions are reinvested.
The formula for computing the average annual total return involves a percentage
obtained by dividing the ending redeemable value by the amount of the initial
investment, taking a root of the quotient (where the root is equivalent to the
number of years in the period) and subtracting 1 from the result. The average
annual total returns of Class B for the fiscal year ended July 31, 1997, for the
five year period ended July 31, 1997 and for the period from October 31, 1988
(commencement of operations) through July 31, 1997 were 24.73%, 13.09% and
14.26%, respectively.
 
    For periods of less than one year, the Fund quotes its total return on a
non-annualized basis. Accordingly, the Fund may compute its aggregate total
return for each of Class A, Class C and Class D 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. The ending redeemable value is
reduced by any CDSC at the end of the period. Based on the foregoing
calculations, the total returns for the period July 28, 1997 through July 31,
1997 were -3.45%, 0.90% and 1.90% for Class A, Class C and Class D,
respectively.
 
    In addition to the foregoing, the Fund may advertise its total return for
each Class 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 imposition of the maximum front-end sales charge for Class A
or the deduction of the CDSC for each of Class B and Class C which, if
reflected, would reduce the performance quoted. For example, the average annual
total return of the Fund may be calculated in the manner described above, but
without deduction for any applicable sales charge. Based on this calculation,
the average annual total returns of Class B for the fiscal year ended July 31,
1997, for the five year period ended July 31, 1997 and for the period October
31, 1988 through July 31, 1997 were 29.73%, 13.33% and 14.26%, respectively.
 
    In addition, the Fund may compute its aggregate total return for each Class
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
 
                                       44
<PAGE>
percentage obtained by dividing the ending value (without the reduction for any
sales charge) by the initial $1,000 investment and subtracting 1 from the
result. Based on the foregoing calculation, the total returns for Class B for
the fiscal year ending July 31, 1997, for the five year period ended July 31,
1997 and for the period October 31, 1988 through July 31, 1997 were 29.73%,
86.95% and 220.97%, respectively. Based on the foregoing calculations, the total
returns for Class A, Class C and Class D for the period July 28 through July 31,
1997 were 1.90%, 1.90% and 1.90%, respectively.
 
    The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 and $100,000 in each Class of shares of the Fund by adding 1 to
the Fund's aggregate total return to date (expressed as a decimal and without
taking into account the effect of any applicable CDSC) and multiplying by
$9,475, $48,000 and $97,000 in the case of Class A (investments of $10,000,
$50,000 and $100,000 adjusted for the initial sales charge) or by $10,000,
$50,000 and $100,000 in the case of each of Class B, Class C and Class D, as the
case may be. Investments of $10,000, $50,000 and $100,000 in each Class at
inception of the Class would have grown to the following amounts at July 31,
1997:

DESCRIPTION OF SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
    The shareholders of the Fund are entitled to a full vote for each full share
held. All of the Trustees have been elected by the shareholders of the Fund,
most recently at a Special Meeting of Shareholders held on May 21, 1997. The
Trustees themselves have the power to alter the number and the terms of office
of the Trustees, and they may at any time lengthen their own terms or make their
terms of unlimited duration and appoint their own successors, provided that
always at least a majority of the Trustees has been elected by the shareholders
of the Fund. Under certain circumstances the Trustees may be removed by action
of the Trustees. The shareholders also have the right under certain
circumstances to remove the Trustees. The voting rights of shareholders are not
cumulative, so that holders of more than 50 percent of the shares voting can, if
they choose, elect all Trustees being selected, while the holders of the
remaining shares would be unable to elect any Trustees.
 
    The Declaration of Trust permits the Trustees to authorize the creation of
additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios) and additional classes of shares
within any series (which would be used to distinguish among the rights of
different categories of shareholders, as might be required by future regulations
or other unforeseen circumstances). The Trustees have not authorized any such
additional series or classes of shares other than as set forth in the
Prospectus.
 
    The Declaration of Trust provides that no Trustee, officer, employee or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer, employee or agent liable to any third persons in 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
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 liabilities in connection with the affairs of the Fund.
 
                                       45

interest. The Fund shall be of unlimited duration subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

NOTES TO FINANCIAL STATEMENTS JULY 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Strategist Fund (the "Fund") is registered under the Investment
Company Act of 1940, as amended (the "Act"), as a non-diversified, open-end
management investment company. The Fund's investment objective is to maximize
the total return of its investments. The Fund seeks to achieve its objective by
actively allocating its assets among major asset categories of equity and
fixed-income securities and money market instruments. The Fund was organized as
a Massachusetts business trust on August 5, 1988 and commenced operations on
October 31, 1988. On July 28, 1997, the Fund commenced offering three additional
classes of shares, with the then current shares, other than shares which were
purchased prior to November 8, 1989 (and with respect to such shares, certain
shares acquired through reinvestment of dividends and capital gains
distributions (collectively the "Old Shares")) and shares held by certain
employee benefit plans established by Dean Witter Reynolds Inc. and its
affiliate, SPS Transaction Services, Inc., designated as Class B shares. The Old
Shares and shares held by those employee benefit plans prior to July 28, 1997
have been designated Class D shares.
 
The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase, some Class
A shares, and most Class B shares and Class C shares are subject to a contingent
deferred sales charge imposed on shares redeemed within one year, six years and
one year, respectively. Class D shares are not subject to a sales charge.
Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.
 
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) an equity security listed or traded on the
New York, American or other domestic or foreign stock exchange is valued at its
latest sale price on that exchange prior to the time when assets are valued; if
there were no sales that day, the security is valued at the latest bid price (in
cases where securities are traded on more than one exchange; the securities are
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Dean Witter

InterCapital, Inc. (the "Investment Manager") that sale or bid prices are not
reflective of a security's market value, portfolio securities are valued at
their fair value as determined in good faith under procedures established by and
under the general supervision of the 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); (4) certain of the Fund's
portfolio securities may be valued by an outside pricing service approved by the
Trustees. The pricing service may utilize a matrix system incorporating security
quality, maturity and coupon as the evaluation model parameters, and/or research
and evaluations by its staff, including review of broker-dealer market price
quotations, if available, in determining what it believes is the fair valuation
of the portfolio securities valued by such pricing service; and (5) 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.
Discounts are accreted over the life of the respective securities. Dividend
income and other distributions are recorded on the ex-dividend date. Interest
income is accrued daily.
 
Investment income, expenses (other than distribution fees), and realized and
unrealized gains and losses are allocated to each class of shares based upon the
relative net asset value on the date the income is earned or expenses and
realized and unrealized gains and losses are incurred. Distribution fees are
charged directly to the respective class.
 
C. 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.
 
D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their

federal tax-basis treatment; temporary differences do not require
reclassification. Dividends and distributions which exceed net investment income
and net realized capital gains for financial reporting purposes but not for tax
purposes are reported as dividends in excess of net investment income or
distributions in excess of net realized capital gains. To the extent they exceed
net investment income and net realized capital gains for tax purposes, they are
reported as distributions of paid-in-capital.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement the Fund pays the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined at the close of
each business day: 0.60% to the portion of daily net assets not exceeding $500
million; 0.55% to the portion of daily net assets exceeding $500 million but not
exceeding $1 billion; 0.50% to the portion of daily net assets exceeding $1
billion but not exceeding $1.5 billion; and 0.475% to the portion of daily net
assets exceeding $1.5 billion.
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of all
personnel, including officers of the Fund who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.
 
3. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The plan
provides that the Fund will pay the Distributor a fee which is accrued daily and
paid monthly at the following annual rates: (i) Class A -- 0.25% of the average
daily net assets of Class A; (ii) Class B -- 1.0% of the lesser of: (a) the
average daily aggregate gross sales of the Class B shares since the
implementation of the Plan on November 8, 1989 (not including reinvestment of
dividend or capital gain distributions) less the average daily aggregate net
asset value of the Class B shares redeemed since the Fund's implementation of
the Plan upon which a contingent deferred sales charge has been imposed or
waived; or (b) the average daily net assets of Class B; and (iii) Class C --
1.0% of the average daily net assets of Class C. In the case of Class A shares,
amounts paid under the Plan are paid to the Distributor for services provided.
In the case of Class B and Class C shares, amounts paid under the Plan are paid
to the Distributor for services

provided and the expenses borne by it and others in the distribution of the
shares of these Classes, including the payment of commissions for sales of these
Classes and incentive compensation to, and expenses of, the account executives
of Dean Witter Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and
Distributor, and others who engage in or support distribution of the 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 these shares to other than current shareholders; and
preparation, printing and distribution of sales literature and advertising
materials. In addition, the Distributor may utilize fees paid pursuant to the
Plan, in the case of Class B shares, to compensate DWR and other selected
broker-dealers for their opportunity costs in advancing such amounts, which
compensation would be in the form of a carrying charge on any unreimbursed
expenses.
 
In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Trustees will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that such excess amounts, including
carrying charges, totaled $37,067,710 at July 31, 1997.
 
In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to account executives may be reimbursed in the subsequent
calendar year. For the period ended July 31, 1997, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.25% and
1.0%, respectively.
 
The Distributor has informed the Fund that for the year ended July 31, 1997, it
received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares of approximately $1,683,000. The shareholders pay such
charges which are not an expense of the Fund.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER STRATEGIST FUND
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter Strategist Fund (the
"Fund") at July 31, 1997, the results of its operations for the year then ended,
the changes in its net assets for each of the two years in the period then ended
and the financial highlights for each of the periods presented, 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 July 31, 1997 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

                                  BOND RATINGS
 
Aaa    Bonds which are rated Aaa are judged to be of the best quality. They
       carry the smallest degree of investment risk and are generally referred
       to as "gilt edge." Interest payments are protected by a large or by an
       exceptionally stable margin and principal is secure. While the various
       protective elements are likely to change, such changes as can be
       visualized are most unlikely to impair the fundamentally strong position
       of such issues.
Aa     Bonds which are rated Aa are judged to be of high quality by all
       standards. Together with the Aaa group they comprise what are generally
       known as high grade bonds. They are rated lower than the best bonds
       because margins of protection may not be as large as in Aaa securities or
       fluctuation of protective elements may be of greater amplitude or there
       may be other elements present which make the long-term risks appear
       somewhat larger than in Aaa securities.
A      Bonds which are rated A possess many favorable investment attributes and
       are to be considered as upper medium grade obligations. Factors giving
       security to principal and interest are considered adequate, but elements
       may be present which suggest a susceptibility to impairment sometime in
       the future.
Baa    Bonds which are rated Baa are considered as medium grade obligations;
       i.e., they are neither highly protected nor poorly secured. Interest
       payments and principal security appear adequate for the present but
       certain protective elements may be lacking or may be characteristically
       unreliable over any great length of time. Such bonds lack outstanding
       investment characteristics and in fact have speculative characteristics
       as well.
       Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.
 
    RATING REFINEMENTS: Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its corporate and
municipal bond rating system. The modifier 1 indicates that the security ranks
in the higher end of its generic rating category; the modifier 2 indicates a
mid-range ranking; and a modifier 3 indicates that the issue ranks in the lower
end of its generic rating category.
 
                            COMMERCIAL PAPER RATINGS
 
    Moody's Commercial Paper ratings are opinions of the ability to repay
punctually promissory obligations not having an original maturity in excess of
nine months. Moody's employs the following three designations, all judged to be
investment grade, to indicate the relative repayment capacity of rated issuers:
Prime-1, Prime-2, Prime-3.
 
    Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                                    BOND RATINGS
 
    A Standard & Poor's bond rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.
 
    The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable. The
ratings are based, in varying degrees, on the
 
                                       65
<PAGE>
following considerations: (1) likelihood of default-capacity and willingness of
the obligor as to the timely payment of interest and repayment of principal in
accordance with the terms of the obligation; (2) nature of and provisions of the
obligation; and (3) protection afforded by, and relative position of, the
obligation in the event of bankruptcy, reorganization or other arrangement under
the laws of bankruptcy and other laws affecting creditors' rights.
 
    Standard & Poor's does not perform an audit in connection with any rating
and may, on occasion, rely on unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.
 
AAA    Debt rated AAA has the highest rating assigned by Standard & Poor's.
       Capacity to pay interest and repay principal is extremely strong.
AA     Debt rated AA has a very strong capacity to pay interest and repay
       principal and differs from the highest-rated issues only in small degree.
A      Debt rated A has a strong capacity to pay interest and repay principal
       although they are somewhat more susceptible to the adverse effects of
       changes in circumstances and economic conditions than debt in
       higher-rated categories.
BBB    Debt rated BBB is regarded as having an adequate capacity to pay interest
       and repay principal. Whereas it normally exhibits adequate protection
       parameters, adverse economic conditions or changing circumstances are
       more likely to lead to a weakened capacity to pay interest and repay
       principal for debt in this category than for debt in higher-rated
       categories.
       Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
NR     Indicates that no rating has been requested, that there is insufficient
       information on which to base a rating or that Standard & Poor's does not
       rate a particular type of obligation as a matter of policy.
 
                            COMMERCIAL PAPER RATINGS
 
    Standard and Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is not a recommendation to purchase or
sell a security. The ratings are based upon current information furnished by the
issuer or obtained by S&P from other sources it considers reliable. The ratings
may be changed, suspended, or withdrawn as a result of changes in or
unavailability of such information. Ratings are graded into group categories,
ranging from "A" for the highest quality obligations to "D" for the lowest. The
categories are as follows:
 
    Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the designation
1, 2 and 3 to indicate the relative degree of safety.
 
A-1 indicates that the degree of safety regarding timely payment is very strong.
 
A-2 indicates capacity for timely payment on issues with this designation is
strong. However, the relative degree of safety is not as overwhelming as for
issues designated "A-1".
 
A-3 indicates a satisfactory capacity for timely payment. Obligations carrying
this designation are, however, somewhat more vulnerable to the adverse effects
of changes in circumstances than obligations carrying the higher designations.
