                    DEAN WITTER HIGH YIELD SECURITIES INC. 

   This Proxy Statement and Prospectus is being furnished to shareholders of 
Dean Witter High Income Securities ("High Income") in connection with an 
Agreement and Plan of Reorganization, dated June 30, 1997 (the 
"Reorganization Agreement"), pursuant to which substantially all the assets 
of High Income will be combined with those of Dean Witter High Yield 
Securities Inc. ("High Yield") in exchange for shares of High Yield. As a 
result of this transaction, shareholders of High Income will become 
shareholders of High Yield and will receive Class B shares of High Yield with 
a value equal to the value of their holdings in High Income. The terms and 
conditions of this transaction are more fully described in this Proxy 
Statement and Prospectus and in the Reorganization Agreement between High 
Income and High Yield, attached hereto as EXHIBIT A. The address of High 
Income is that of High Yield set forth above. This Proxy Statement also 
constitutes a Prospectus of High Yield, which is dated,        , 1997, filed 
by High Yield with the Securities and Exchange Commission (the "Commission") 
as part of its Registration Statement on Form N-14 (the "Registration

primary investment objective is to provide a high level of current income. As 
a secondary objective, High Yield seeks capital appreciation, but only when 
consistent with its primary objective. High Yield seeks high current income 
by investing principally in fixed-income securities which are rated in the 
lower categories by established rating services (Baa or lower by Moody's 
Investors Service, Inc. or BBB or lower by Standard & Poor's Corporation) or 
are non-rated securities of comparable quality. Such securities are commonly 
known as "junk bonds." 

   This Proxy Statement and Prospectus sets forth concisely information about 
High Yield that shareholders of High Income should know before voting on the 
Reorganization Agreement. A copy of the Prospectus for High Yield, dated July 
28, 1997, is attached as EXHIBIT B and is incorporated herein by reference. 
Also enclosed and incorporated herein by reference is High Yield's Annual
Report for the fiscal year ended August 31,1996 and the succeeding Semi-Annual 
Report for the six months ended February 28, 1997. A Statement of Additional 
Information relating to the Reorganization, described in this Proxy Statement 
and Prospectus (the "Additional Statement"), dated August   , 1997, has been 
filed with the Commission and is also incorporated herein by reference. Also 
incorporated herein by reference are High Income's Prospectus dated June 16, 
1997, and High Income's Annual Report for its fiscal year ended March 31, 
1997. Such documents are available without charge by calling (212) 392-2550 
or (800) 526-3143 (TOLL FREE). 

Investors are advised to read and retain this Proxy Statement and Prospectus 
                            for future reference. 

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND 
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE 
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED 
ON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE 
CONTRARY IS A CRIMINAL OFFENSE. 

          This Proxy Statement and Prospectus is dated August   , 1997.

                         TO BE HELD OCTOBER 21, 1997 

                                 INTRODUCTION 

GENERAL 

   This Proxy Statement and Prospectus is being furnished to the shareholders 
of Dean Witter High Income Securities ("High Income"), an open-end 
diversified management investment company, in connection with the 
solicitation by the Board of Trustees of High Income (the "Board") of proxies 
to be used at the Special Meeting of Shareholders of High Income to be held 
at the Career Development Room, 61st Floor, Two World Trade Center, New York, 
New York 10048 at 9:00 A.M., New York time, on October 21, 1997, and any 
adjournments thereof (the "Meeting"). It is expected that the mailing of this 
Proxy Statement and Prospectus will be made on or about August  , 1997. 

   At the Meeting, High Income shareholders ("Shareholders") will consider 
and vote upon an Agreement and Plan of Reorganization, dated June 30, 1997 
(the "Reorganization Agreement"), between High Income and Dean Witter 
HighYield Securities Inc. ("High Yield") pursuant to which substantially all 
of the assets of High Income will be combined with those of High Yield in 
exchange for shares of High Yield. As a result of this transaction, 
Shareholders will become shareholders of High Yield and will receive Class B 
shares of High Yield equal to the value of their holdings in High Income on 
the date of such transaction (the "Reorganization"). The shares to be issued 
by High Yield pursuant to the Reorganization will be Class B shares of High 
Yield which will be issued at net asset value without an initial sales charge 
(the "High Yield Shares"). Further information relating to High Yield, its 
Class B shares as well as the other three classes of shares (each, a "Class" 
and collectively, the "Classes") offered by High Yield, is set forth herein 
and in High Yield's current Prospectus, dated July 28, 1997 ("High Yield's 
Prospectus"), attached to this Proxy Statement and Prospectus and 
incorporated herein by reference. 

   The information concerning High Income contained herein has been supplied 
by High Income and the information concerning High Yield contained herein has 
been supplied by High Yield. 

RECORD DATE; SHARE INFORMATION 

   The Board has fixed the close of business on       , 1997 as the record 
date (the "Record Date") for the determination of the Shareholders entitled 
to notice of, and to vote at, the Meeting. As of the Record Date, there were 
    shares of High Income issued and outstanding. Shareholders on the Record 
Date are entitled to one vote per share on each matter submitted to a vote at 
the Meeting. A majority of the outstanding shares entitled to vote, 
represented in person or by proxy, will constitute a quorum at the Meeting. 


<PAGE>
   [To the knowledge of the Board, as of the Record Date, no person owned of 
record or beneficially 5% or more of the outstanding shares of High Income.] 
[As of the Record Date, the trustees and officers of High Income, as a group, 
owned less than 1% of the outstanding shares of High Income.] 

   [To the knowledge of High Yield's Board of Directors, as of the Record 
Date, no person owned of record or beneficially 5% or more of the outstanding 
shares of High Yield. As of the Record Date, the directors and officers of 
High Yield, as a group, owned less than 1% of the outstanding shares of High 
Yield.] 

PROXIES 

   The enclosed form of proxy, if properly executed and returned, will be 
voted in accordance with the choice specified thereon. The proxy will be 
voted in favor of the Reorganization Agreement unless a choice is indicated 
to vote against or to abstain from voting on the Reorganization Agreement. 
The Board knows of no business, other than that set forth in the Notice of 
Special Meeting of Shareholders, to be presented for consideration at the 
Meeting. However, the proxy confers discretionary authority upon the persons 
named therein to vote as they determine on other business, not currently 
contemplated, which may come before the Meeting. Abstentions and, if 
applicable, broker "non-votes" will not count as votes in favor of the 
Reorganization Agreement, and broker "non-votes" will not be deemed to be 
present at the meeting for purposes of determining whether the Reorganization 
Agreement has been approved. Broker "non-votes" are shares held in street 
name for which the broker indicates that instructions have not been received 
from the beneficial owners or other persons entitled to vote and for which 
the broker does not have discretionary voting authority. If a Shareholder 
executes and returns a proxy but fails to indicate how the votes should be 
cast, the proxy will be voted in favor of the Reorganization Agreement. The 
proxy may be revoked at any time prior to the voting thereof by: (i) 
delivering written notice of revocation to the Secretary of High Income at 
Two World Trade Center, New York, New York 10048; (ii) attending the Meeting 
and voting in person; or (iii) signing and returning a new proxy (if returned 
and received in time to be voted). Attendance at the Meeting will not in and 
of itself revoke a proxy. 

   In the event that the necessary quorum to transact business or the vote 
required to approve or reject the Reorganization Agreement is not obtained at 
the Meeting, the persons named as proxies may propose one or more 
adjournments of the Meeting for a total of not more than 60 days in the 
aggregate to permit further solicitation of proxies. Any such adjournment 
will require the affirmative vote of the holders of a majority of High 
Income's shares present in person or by proxy at the Meeting. The persons 
named as proxies will vote in favor of such adjournment those proxies which 
they are entitled to vote in favor of the Reorganization Agreement and will 
vote against any such adjournment those proxies required to be voted against 
the Reorganization Agreement. 

EXPENSES OF SOLICITATION 

   All expenses of this solicitation, including the cost of preparing and 
mailing this Proxy Statement and Prospectus, will be borne by Dean Witter 
InterCapital Inc. (the "Investment Manager" or "InterCapital"). In addition 
to the solicitation of proxies by mail, proxies may be solicited by officers 
and regular employees or certain affiliates of High Income, including 
InterCapital and/or Dean Witter Trust Company ("DWTC"), without compensation 
other than regular compensation, personally or by mail, telephone, telegraph 
or otherwise. Brokerage houses, banks and other fiduciaries may be requested 
to forward soliciting material to the beneficial owners of shares and to 
obtain authorization for the execution of proxies.

   DWTC may call Shareholders to ask if they would be willing to have their 
votes recorded by telephone. The telephone voting procedure is designed to 
authenticate Shareholders' identities, to allow Shareholders to authorize the 
voting of their shares in accordance with their instructions and to confirm 
that their instructions have been recorded properly. No recommendation will 
be made as to how a Shareholder should vote on the Reorganization Agreement 
other than to refer to the recommendation of the Board. High Income has been 
advised by counsel that these procedures are consistent with the requirements 
of applicable law. Shareholders voting by telephone will be asked for their 
social security number or other identifying information and will be given an 
opportunity to authorize proxies to vote their shares in accordance with 
their instructions. To ensure that the Shareholders' instructions have been 
recorded correctly they will receive a confirmation of their instructions in 
the mail. A special toll-free number will be available in case the 
information contained in the confirmation is incorrect. Although a 
Shareholder's vote may be taken by telephone, each Shareholder will receive a 
copy of this Prospectus and Proxy Statement and may vote by mail using the 
enclosed proxy card. 

VOTE REQUIRED 

   Approval of the Reorganization Agreement by the Shareholders requires the 
affirmative vote of a majority (i.e., more than 50%) of the outstanding 
shares of High Income represented in person or by proxy and entitled to vote 
at the Meeting, provided a quorum is present at the Meeting. If the 
Reorganization Agreement is not approved by Shareholders, High Income will 
continue in existence and the Board will consider alternative actions.

                                   SYNOPSIS 

   The following is a synopsis of certain information contained in or 
incorporated by reference in this Proxy Statement and Prospectus. This 
synopsis is only a summary and is qualified in its entirety by the more 
detailed information contained or incorporated by reference in this Proxy 
Statement and Prospectus and the Reorganization Agreement. Shareholders 
should carefully review this Proxy Statement and Prospectus and the 
Reorganization Agreement in their entirety and, in particular, High Yield's 
Prospectus, which is attached to this Proxy Statement and incorporated herein 
by reference. 

THE REORGANIZATION 

   The Reorganization Agreement provides for the transfer of substantially 
all the assets of High Income, subject to stated liabilities, to High Yield 
in exchange for the High Yield Shares. The aggregate net asset value of the 
High Yield Shares issued in the exchange will equal the aggregate value of 
the net assets of High Income received by High Yield. On or after the closing 
date scheduled for the Reorganization (the "Closing Date"), High Income will 
distribute the High Yield Shares received by High Income to Shareholders as 
of the Valuation Date (as defined below under "The Reorganization Agreement") 
in complete liquidation of High Income and High Income will thereafter be 
dissolved and deregistered under the Investment Company Act of 1940, as 
amended (the "1940 Act"). As a result of the Reorganization, each Shareholder 
will receive that number of full and fractional High Yield Shares equal in 
value to such Shareholder's pro rata interest in the net assets transferred 
to High Yield. Shareholders holding certificates representing their shares 
will not be required to surrender their certificates in connection with the 
Reorganization. However, such Shareholders will have to surrender such 
certificates in order to receive certificates representing High Yield Shares 
or to redeem, transfer or exchange the High Yield Shares received. The Board 
has determined that the interests of Shareholders will not be diluted as a 
result of the Reorganization. 

   FOR THE REASONS SET FORTH BELOW UNDER "THE REORGANIZATION --THE BOARD'S 
CONSIDERATION," THE BOARD, INCLUDING THE TRUSTEES WHO ARE NOT "INTERESTED 
PERSONS" OF HIGH INCOME ("INDEPENDENT TRUSTEES"), AS THAT TERM IS DEFINED IN 
THE 1940 ACT, HAS CONCLUDED THAT THE REORGANIZATION IS IN THE BEST INTERESTS 
OF HIGH INCOME AND ITS SHAREHOLDERS AND RECOMMENDS APPROVAL OF THE 
REORGANIZATION AGREEMENT. 

FEE TABLE 

   High Income and High Yield each pay expenses for management of their 
assets, distribution of their shares and other services, and those expenses 
are reflected in the net asset value per share of each such fund. The 
following table illustrates expenses and fees that a Shareholder incurred 
during High Income's fiscal year ended March 31, 1997. On July 28, 1997, High 
Yield began offering its shares in multiple classes, each with different 
distribution arrangements and sales charges. Class B shares of High Yield 
will be issued to High Income Shareholders in connection with the 
Reorganization. Accordingly, expenses of High Yield that are set forth in the 
table are for the fiscal year ended August 31, 1996 but they have been 
restated to reflect the fees and expenses applicable to Class B shares 
("Class B Fees and Expenses"). The table below also sets forth pro forma fees 
for the surviving combined fund (High Yield) reflecting what the fee schedule 
would have been at March 31, 1997, if the Reorganization had been consummated 
twelve (12) months prior to that date and assuming Class B Fees and Expenses.

and expenses applicable to High Yield's Class B shares as well as the other 
three classes of High Yield shares is set forth herein and in High Yield's 
Prospectus, attached hereto and incorporated herein by reference.

1       During High Yield's fiscal year ended August 31, 1996, shares of High 
        Yield were sold exclusively with a front-end sales charge, the 
        maximum rate of which was 5.50% of the offering price. On July 28, 
        1997, however, High Yield began offering four Classes of shares. 
        Classes B, C and D are sold without a front-end sales charge; Class A 
        shares are sold with a maximum front-end charge of 4.25%. 

2       During High Yield's fiscal year ended August 31, 1996, there were no 
        CDSCs imposed upon redemptions and/or repurchases of shares of High 
        Yield. However, Class B shares of High Yield are currently offered 
        and subject to the CDSC set forth in the table. High Yield shares 
        held by certain employee benefit plans, however, are subject to a 
        different CDSC schedule (see "Purchases, Exchanges and Redemptions" 
        below). 

                                5           
<PAGE>
3       The CDSC schedule of High Income (with the lower maximum CDSC of 
        4.00%) will continue to apply (after the Reorganization) to the High 
        Yield Shares acquired by Shareholders as a result of the 
        Reorganization, and, accordingly, Shareholders acquiring High Yield 
        Shares as a result of the Reorganization will not pay a higher CDSC 
        on redemption of the High Yield Shares than the rate currently in 
        effect for redemptions of their High Income shares so long as such 
        Shareholders do not (i) exchange the High Yield Shares for shares of 
        another Dean Witter Fund which has a higher maximum CDSC rate than 
        4.00% (a "Higher CDSC Fund") or (ii) having exchanged to Dean Witter 
        Global Short-Term Income Fund Inc. or any Exchange Fund (as such term 
        is defined under "Purchases, Exchanges and Redemptions" below), 
        re-exchange back to High Yield after the Reorganization. Under such 
        circumstances, the CDSC schedule of the Higher CDSC Fund acquired in 
        the exchange will become applicable upon the redemption of such 
        fund's shares, or in the case of shares of any of the Exchange Funds 
        or Dean Witter Global Short-Term Income Fund acquired in an exchange 
        and then subsequently re-exchanged back into High Yield, the CDSC 
        applicable to High Yield shares will be charged upon the redemption 
        of any such shares (see "Purchases, Exchanges and Redemptions" 
        below). 

4       This rate assumes that the level of assets upon the combination of 
        the two funds would have caused a breakpoint in the advisory fee of 
        High Yield to be reached, thus, a scaling down of the advisory fee to 
        the effective advisory fee rate shown. 

5       The 12b-1 fee is accrued daily and payable monthly. The 12b-1 fee is, 
        in the case of High Income, calculated as a percentage of the lesser 
        of (a) the average daily net sales or (b) the average daily net 
        assets of the Fund and, in the case of High Yield, calculated as a 
        percentage of average daily net assets. With respect to each fund, a 
        portion of the 12b-1 fee equal to 0.20% of average daily net assets 
        is characterized as a service fee within the meaning of the National 
        Association of Securities Dealers, Inc. ("NASD") guidelines. 

6       For the fiscal year ended August 31, 1996, there was no 12b-1 fee 
        paid by High Yield. However, on June 30, 1997, a 12b-1 fee calculated 
        at the annual rate of 0.75% of the average daily net assets of Class 
        B was authorized for Class B shares of High Yield to take effect upon 
        implementation of the multiple class distribution structure on July 
        28, 1997. The actual total fund operating expense ratio for High 
        Yield during the fund's fiscal year ended August 31, 1996 was 0.66% 
        (this rate reflects that no 12b-1 fees were incurred during this 
        period).

Hypothetical Expenses 

   To attempt to show the effect of these expenses on an investment over 
time, the hypotheticals shown below have been created. Assuming that an 
investor makes a $1,000 investment in either High Income or Class B Shares of 
High Yield or the new combined fund (Class B shares of High Yield), that the 
annual return is 5% and that the operating expenses for each fund are the 
ones shown in the chart above; if the investment was redeemed at the end of 
each period shown below, the investor would incur the following expenses by 
the end of each period shown: 

<TABLE>

                                1 YEAR   3 YEARS   5 YEARS   10 YEARS

Pro Forma Combined (Class B)     $63       $71       $91       $157 
</TABLE>

If such investment was not redeemed, the investor would incur the following 
expenses:

Pro Forma Combined (Class B)     $13       $41       $71       $157 
</TABLE>

   The above example should not be considered a representation of past or 
future expenses or performance. Actual operating expenses may be greater or 
less than those shown. Long-term shareholders of High Income and Class B 
shareholders of High Yield may pay more in sales charges including 
distribution fees than the economic equivalent of the maximum front-end sales 
charges permitted by the NASD. 

TAX CONSEQUENCES OF THE REORGANIZATION 

   As a condition to the Reorganization, High Income will receive an opinion 
of Gordon Altman Butowsky Weitzen Shalov & Wein to the effect that the 
Reorganization will constitute a tax-free reorganization for federal income 
tax purposes, and that no gain or loss will be recognized by High Income or 
the shareholders of High Income for Federal income tax purposes as a result 
of the transactions included in the Reorganization. For further information 
about the tax consequences of the Reorganization, see "The Reorganization -- 
Tax Aspects of the Reorganization" below. 

COMPARISON OF HIGH INCOME AND HIGH YIELD 

   INVESTMENT OBJECTIVES AND POLICIES. High Income and High Yield have 
identical investment objectives, which is primarily to seek a high level of 
current income and, as a secondary objective, to seek capital appreciation 
(but only when consistent with the primary objective). High Yield seeks to 
achieve its investment objectives by investing principally in fixed-income 
securities rated Baa or lower by Moody's Investors Service, Inc. ("Moody's"), 
or BBB or lower by Standard & Poor's Corporation ("Standard & Poor's"). High 
Income also invests principally in fixed-income securities to achieve its 
objectives; however, such fixed-income securities are defined only to include 
those rated Ba or lower by Moody's, or BB or lower by Standard & Poor's. Both 
funds do not have any minimum quality rating standard for its 

                                7           
<PAGE>
investments. Both funds also consider non-rated securities for investment 
when InterCapital believes that the financial condition of the issuers of 
such securities, or the protection afforded by the terms of the securities 
themselves, makes them appropriate investments of the funds. With respect to 
High Income, the fund seeks to maintain under normal circumstances a dollar 
weighted average maturity of between five and ten years. High Yield does not 
have a specific policy as to the portfolio's dollar weighted average 
maturity. 

   The investment policies of both funds are essentially the same; the 
principal differences between them are described under "Comparison of 
Investment Objectives, Policies and Restrictions" below. 

   The investment policies of both High Income and High Yield are not 
fundamental and may be changed by their respective Boards of 
Trustees/Directors. 

   INVESTMENT MANAGEMENT AND DISTRIBUTION PLAN FEES. High Income and High 
Yield obtain investment management services from InterCapital. With respect 
to High Income, the fund pays InterCapital monthly compensation calculated 
daily by applying the annual rate of 0.50% to the first $500 million of the 
fund's average net assets and 0.425% to the fund's average net assets 
exceeding $500 million. With respect to High Yield, the fund pays 
InterCapital monthly compensation calculated daily by applying the annual 
rate of: 0.50% to the fund's first $500 million of average net assets; 0.425% 
to the fund's next $250 million of average net assets; 0.375% to the fund's 
next $250 million of average net assets; 0.35% to the fund's next $1 billion 
of average net assets; 0.325% to the next $1 billion of the fund's average 
net assets; and 0.30% to the fund's average net assets exceeding $3 billion. 

   Both High Income and High Yield have adopted distribution plans ("Plans") 
pursuant to Rule 12b-1 under the 1940 Act. Pursuant to High Income's Plan, 
the fund pays to Dean Witter Distributors Inc. (the "Distributor") a fee, 
which is accrued daily and payable monthly, at the annual rate of 0.80% of 
the lesser of (a) the average daily net sales of such fund's shares, or (b) 
the average net assets of the fund. The 12b-1 fee applicable to Class B 
shares of High Yield is accrued daily and payable monthly at the annual rate 
of 0.75% of average daily net assets allocated to that Class. For further 
information relating to the 12b-1 fees applicable to Class B shares as well 
as High Yield's other classes of shares, see the section entitled "Purchase 
of Fund Shares" in High Yield's Prospectus, attached hereto. Rule 12b-1 fees 
compensate the Distributor for the services provided and the expenses borne 
by the Distributor and others in distribution of the funds' shares. The 
Distributor also receives the proceeds of any CDSC paid by the funds' 
shareholders at the time of redemption. (High Income's and High Yield's 
respective CDSC schedules are set forth below under "Purchases, Exchanges and 
Redemptions.") 

   OTHER SIGNIFICANT FEES. Both High Income and High Yield pay additional 
fees in connection with their operations, including legal, auditing, transfer 
agent and custodial fees. See "Synopsis -- Fee Table" above for the 
percentage of average net assets represented by such "Other Expenses." 

   PURCHASES, EXCHANGES AND REDEMPTIONS. High Income continuously issues its 
shares to investors at a price equal to net asset value at the time of such 
issuance. However, redemptions and/or repurchases are subject, under most 
circumstances, to a CDSC. Likewise, Class B shares of High Yield are 
currently offered at net asset value and redemptions and/or repurchases are 
subject under most circumstances to a CDSC. The following are the respective 
CDSC schedules applicable to each of High Income and Class B shares of High 
Yield. Class B shares held by certain qualified employer-sponsored benefit 
plans are subject to a reduced CDSC schedule.

</TABLE>

   The lower CDSC schedule of High Income will continue to apply to 
Shareholders only with respect to the High Yield Shares acquired in the 
Reorganization, unless such Shareholder (i) exchanges his/her High Yield 
Shares after the Reorganization for a fund with a higher CDSC schedule than 
High Income (a "Higher CDSC Fund") or (ii) having exchanged to Dean Witter 
Global Short-Term Income Fund Inc. 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 (collectively, the "Exchange Funds"), 
re-exchanges back to High Yield after the Reorganization. Under such 
circumstances, the CDSC schedule applicable to the Higher CDSC Fund shares 
acquired in the exchange will apply to redemptions of such fund's shares or, 
in the case of shares of any of the Exchange Funds acquired in an exchange 
and then subsequently re-exchanged back into High Yield, the CDSC schedule 
for High Yield (set forth in the table above) will apply to redemptions of 
any of such shares. 

   The CDSC charge is paid to the Distributor. Shares of High Yield and High 
Income are distributed by the Distributor and offered by Dean Witter Reynolds 
Inc. and other dealers who have entered into selected dealer agreements with 
the Distributor. For further information relating to the CDSC schedules 
applicable to Class B and the other classes of High Yield's shares, see the 
section entitled "Purchase of Fund Shares" in High Yield's Prospectus. 

   Shares of each Class of High Yield may be exchanged for shares of the same 
Class of any other Dean Witter Fund that offers its shares in more than one 
Class (the "Multi-Class Funds") or any of Dean Witter Global Short-Term 
Income Fund Inc. and Dean Witter National Municipal Trust ("CDSC Funds"), 
without the imposition of an exchange fee. High Income shares also may be 
exchanged for Class B shares of any Multi-Class Fund or for shares of either 
CDSC Fund. Both funds may be exchanged for shares of any of the Exchange 
Funds. With respect to High Income and High Yield, no CDSC is imposed at the 
time of any exchange, although any applicable CDSC will be imposed upon 
ultimate redemption. During the period of time a shareholder remains in an 
Exchange Fund, the holding period (for purposes of determining the CDSC rate) 
is frozen. Both High Income and High Yield provide telephone exchange 
privileges to their shareholders. For greater details relating to exchange 
privileges applicable to High Yield, see the section entitled "Shareholder 
Services" in High Yield's Prospectus. 

   Shareholders of High Income and High Yield may redeem their shares for 
cash at any time at the net asset value per share next determined; however, 
such redemption proceeds may be reduced by the amount of any applicable CDSC. 
Both High Income and High Yield offer a reinstatement privilege whereby a 
shareholder who has not previously exercised such privilege whose shares have 
been redeemed or repurchased may, within thirty days, in the case of High 
Income, and within thirty-five days, in the case of High Yield, after the 
date of redemption or repurchase, reinstate any portion or all of the 
proceeds 

                                9           
<PAGE>
thereof in shares of High Income or Class B shares of High Yield, 
respectively, and receive a pro rata credit for any CDSC paid in connection 
with such redemption or repurchase. High Income and High Yield may redeem 
involuntarily, at net asset value, most accounts valued at less than $100. 

   DIVIDENDS. Dividends from both High Income's and High Yield's anticipated 
net investment income are declared and paid monthly and net short-term 
capital gains and long-term capital gains distributions, if any, are paid at 
least annually. Dividends and capital gains distributions of both High Income 
and High Yield are automatically reinvested in additional shares at net asset 
value unless the shareholder elects to receive cash. 

                            PRINCIPAL RISK FACTORS 

   The net asset value of High Yield's and High Income's shares will 
fluctuate with changes in the market value of their respective portfolio 
securities. Both High Income and High Yield invest principally in high yield 
fixed-income securities, which, compared with higher rated lower yielding 
fixed-income securities, may be subject to greater risk of loss of income and 
principal, including the risk of default, and greater risk of increases and 
decreases in net asset value due to market fluctuations. The overall risks of 
investments in both funds are substantially similar. 

   The foregoing discussion is a summary of the principal risk factors. For a 
more complete discussion of the risks of each fund, see "Investment 
Objectives and Policies --Risk Considerations" in High Income's Prospectus 
and "Investment Objectives and Policies -- Special Risk Considerations" in 
High Yield's Prospectus. 

                              THE REORGANIZATION 

THE PROPOSAL 

   The Board of Trustees of High Income, including the Independent Trustees, 
having reviewed High Income's financial position and the prospects for 
achieving economies of scale through the Reorganization, determined that the 
Reorganization is in the best interests of High Income and its Shareholders 
and that the interests of High Income's Shareholders will not be diluted as a 
result thereof, recommends approval of the Reorganization by High Income 
Shareholders. 

THE BOARD'S CONSIDERATION 

   At a meeting held on June 30, 1997, the Board, including all of the 
Independent Trustees, unanimously approved the Reorganization Agreement and 
determined to recommend that Shareholders of High Income approve the 
Reorganization Agreement. In reaching this decision, the Board made an 
extensive inquiry into a number of factors, particularly the comparative 
expenses to be incurred in the operations of High Income and Class B shares 
of High Yield. The Board also considered other factors, including, but not 
limited to: the comparative investment performance and past growth in assets 
of High Income and High Yield; the compatibility of the investment 
objectives, policies, restrictions and portfolios of High Income and High 
Yield; the terms and conditions of the Reorganization which would affect the 
price of shares to be issued in the Reorganization; the tax-free nature of 
the Reorganization; and any direct or indirect costs to be incurred by High 
Income and High Yield in connection with the Reorganization. 

                               10           
<PAGE>
   In recommending the Reorganization to Shareholders, the Board of High 
Income considered that the Reorganization would have the following benefits 
for Shareholders: 

   1. Once the Reorganization is consummated, the expenses which would be 
borne by Class B shareholders of the "combined fund" should be lower on a 
percentage basis than the actual expenses per share of High Income. In part, 
this is because the rate of the investment management fee payable by the 
surviving High Yield fund would be lower than the fees currently paid by High 
Income as a result of breakpoints in the management fee of High Yield 
achieved through the combination of fund assets resulting from the 
Reorganization. 

   In addition, the rate of the 12b-1 fee payable by High Yield will be lower 
than those currently paid by High Income. As discussed in the "Fee Table," 
above, the funds use different formulas to calculate 12b-1 fees: in 
accordance with its two-part formula, High Income has been paying 12b-1 fees 
at the rate of 0.80% of average daily net assets (which has been lower than 
average daily net sales since inception of the fund). The 12b-1 fee payable 
by High Yield Shares will be 0.75% of average daily net assets. 

   Shareholders who remain invested in High Yield for approximately ten years 
from the Closing Date (as defined below) will receive an additional benefit 
as a result of the automatic conversion of Class B shares of High Yield into 
Class A shares of High Yield after such period. As discussed more fully in 
High Yield's Prospectus, attached hereto, once Shareholders are converted to 
Class A they will be subject to the Class's 12b-1 fee of only 0.25% of the 
average daily net assets of that Class. For greater details regarding the 
conversion feature, including the method by which the 10 year period is 
calculated and the treatment of reinvested dividends, see "Purchase of Fund 
Shares" in High Yield's Prospectus. 

   Furthermore, to the extent that the Reorganization would result in 
Shareholders becoming shareholders of a combined larger fund, further 
economies of scale could be achieved since various fixed expenses (e.g., 
auditing and legal) can be spread over a larger number of shares. The Board 
noted that High Income's expense ratio, for its fiscal year ended March 31, 
1997, was 1.39%, whereas the expense ratio for High Yield was 1.41% (based on 
the fiscal year ended August 31, 1996 assuming a 0.75% 12b-1 fee, as well as 
a reduced management fee). The Board further noted that the combined fund is 
expected to have a lower expense ratio than both funds currently do (taking 
into account the other assumptions described in the "Fee Table," above). 

   2. Shareholders would have a continued participation in the high yield 
fixed-income markets through investment in High Yield, which has identical 
investment objectives and substantially similar investment policies and 
restrictions to those of High Income. Upon consummation of the 
Reorganization, the lower CDSC schedule of High Income will continue to apply 
(with respect to the High Yield Shares acquired in the Reorganization), 
except under certain circumstances in which such High Yield Shares are 
exchanged for another fund, as described in "Comparison of High Income and 
High Yield -- Purchases, Exchanges and Redemptions." 

   3. The Reorganization will constitute a tax-free reorganization for 
federal income tax purposes, and no gain or loss will be recognized by High 
Income or its Shareholders for federal income tax purposes as a result of 
transactions included in the Reorganization. 

   4. The Board also took into consideration that effective July 28, 1997, 
High Yield Shares will also be available to certain investors at net asset 
value and, therefore, absent the Reorganization, High Yield 

                               11           
<PAGE>
will compete for investor funds directly with High Income. The Reorganization 
should allow for more concentrated selling efforts to the benefit of both 
High Income and High Yield shareholders and avoid the inefficiencies 
associated with the operation and distribution of substantially similar 
funds. 

   The Board of Directors of High Yield, including a majority of such 
Directors who are not "interested persons" of High Yield, also have 
determined that the Reorganization is in the best interests of High Yield and 
its shareholders and that the interests of existing shareholders of High 
Yield will not be diluted as a result thereof. The transaction will enable 
High Yield to acquire investment securities which are consistent with High 
Yield's investment objective, without the brokerage costs attendant to the 
purchase of such securities in the market. Furthermore, the addition of High 
Income's assets to High Yield's portfolio is expected to result in the 
economies of scale described above. The Board also considered the limitations 
on the use of High Yield's capital loss carryforwards that would result from 
the Reorganization (see "Tax Aspects of the Reorganization"), and upon 
consideration of all factors deemed relevant, including the likelihood that 
the tax carryforward would be utilized, determined, in the exercise of its 
reasonable business judgment, that the potential benefits of the 
Reorganization outweighed any adverse effects. 

THE REORGANIZATION AGREEMENT 

   The terms and conditions under which the Reorganization would be 
consummated, as summarized below, are set forth in the Reorganization 
Agreement. This summary is qualified in its entirety by reference to the 
Reorganization Agreement, a copy of which is attached as Exhibit A to this 
Proxy Statement and Prospectus. 

   The Reorganization Agreement provides that (i) High Income will transfer 
all of its assets, including portfolio securities, cash (other than cash 
amounts retained by High Income as a "Cash Reserve" in the amount sufficient 
to discharge its liabilities not discharged prior to the Valuation Date (as 
defined below) and for expenses of the dissolution), cash equivalents and 
receivables to High Yield on the Closing Date in exchange for the assumption 
by High Yield of High Income's stated liabilities, including all expenses, 
costs, charges and reserves, as reflected on an unaudited statement of assets 
and liabilities of High Income prepared by the Treasurer of High Income as of 
the Valuation Date (as defined below) in accordance with generally accepted 
accounting principles consistently applied from the prior audited period, and 
the delivery of High Yield Shares, (ii) such High Yield Shares would be 
distributed to the Shareholders of High Income on the Closing Date or as soon 
as practicable thereafter, (iii) High Income would be dissolved and (iv) the 
outstanding shares of High Income would be canceled. 

   The number of High Yield Shares to be delivered to High Income will be 
determined by dividing the value of High Income assets acquired by High Yield 
(net of stated liabilities assumed by High Yield) by the net asset value of a 
High Yield Share; these values will be calculated as of 4:00 p.m. New York 
City time on the third day that the New York Stock Exchange is open for 
business following the receipt of the requisite approval by the shareholders 
of High Income of the Reorganization Agreement or at such other time as High 
Income and High Yield may agree (the "Valuation Date"). As an illustration, 
if on the Valuation Date, High Income were to have securities with a market 
value of $95,000 and cash in the amount of $10,000 (of which $5,000 was to be 
retained by it as the Cash Reserve), the value of the assets which would be 
transferred to High Yield would be $100,000. If the net asset value per share 
of High Yield were $10 per share at the close of business on the Valuation 
Date, the number of shares to be issued would be 10,000 ($100,000 (divided 
by) $10). These 10,000 Class B shares of High Yield would be distributed to 
the former 

                               12           
<PAGE>
shareholders of High Income. This example is given for illustration purposes 
only and does not bear any relationship to the dollar amounts or shares 
expected to be involved in the Reorganization. 

   On the Closing Date or as soon as practicable thereafter, High Income will 
distribute pro rata to its Shareholders of record as of the close of business 
on the Valuation Date, the High Yield Shares it receives. High Yield will 
cause its transfer agent to credit and confirm an appropriate number of High 
Yield Shares to each Shareholder. Certificates for High Yield Shares will be 
issued upon written request of a Shareholder but only for whole shares, with 
fractional shares credited to the name of the Shareholder on the books of 
High Yield. Such Shareholders who wish certificates representing their High 
Yield Shares must, after receipt of their confirmations, make a written 
request to High Yield's transfer agent, Dean Witter Trust Company, Harborside 
Financial Center, Jersey City, New Jersey 07311. Shareholders holding 
certificates representing their shares will not be required to surrender 
their certificates in connection with the Reorganization. However, such 
Shareholders will have to surrender such certificates (or provide indemnities 
reasonably acceptable to High Yield in respect of lost certificates) in order 
to receive certificates representing High Yield Shares or to redeem, transfer 
or exchange the High Yield Shares received. 

   The Closing Date will be the next business day following the Valuation 
Date. The consummation of the Reorganization is contingent upon the approval 
of the Reorganization by the shareholders of High Income and the receipt of 
the other opinions and certificates set forth in Sections 6, 7 and 8 of the 
Reorganization Agreement and the occurrence of the events described in those 
Sections, certain of which may be waived by High Income or High Yield. The 
Reorganization Agreement may be amended in any mutually agreeable manner, 
except that no amendment may be made subsequent to the Meeting which would 
detrimentally affect the value of the shares of High Yield to be distributed. 
InterCapital will bear all of the expenses associated with the 
Reorganization. Management estimates that such expenses associated with the 
Reorganization will not exceed $   . 

   The Reorganization Agreement may be terminated and the Reorganization 
abandoned at any time, before or after approval by High Income's Shareholders 
by mutual consent of High Income and High Yield. In addition, either party 
may terminate the Reorganization Agreement upon the occurrence of a material 
breach of the Reorganization Agreement by the other party or if, by January 
31, 1998, any condition set forth in the Reorganization Agreement has not 
been fulfilled or waived by the party entitled to its benefits. 

   Under the Reorganization Agreement, within one year after the Closing 
Date, High Income shall: either pay or make provision for all of its 
liabilities and distribute any remaining amount of the Cash Reserve (after 
paying or making provision for such liabilities and the estimated cost of 
making the distribution) to former shareholders of High Income that received 
High Yield Shares. High Income shall be dissolved and deregistered as an 
investment company promptly following the distributions of shares of High 
Yield to Shareholders of record of High Income. 

   The effect of the Reorganization is that Shareholders who vote their 
shares in favor of the Reorganization Agreement are electing to sell their 
shares of High Income (at net asset value on the Valuation Date calculated 
after subtracting the Cash Reserve) and reinvest the proceeds in High Yield 
Shares at net asset value and without recognition of taxable gain or loss for 
federal income tax purposes. See "Tax Aspects of the Reorganization" below. 
As noted in "Tax Aspects of the Reorganization" below, if High Income 
recognizes net gain from the sale of securities prior to the Closing Date, 
such gain, to the extent not offset by capital loss carryovers, will be 
distributed to Shareholders prior to the Closing Date and will be taxable to 
Shareholders as capital gain. 

                               13           
<PAGE>
   Shareholders will continue to be able to redeem their shares of High 
Income at net asset value next determined after receipt of the redemption 
request (subject to any applicable CDSC) until the close of business on the 
business day next preceding the Closing Date. Redemption requests received by 
High Income thereafter will be treated as requests for redemption of shares 
of High Yield. 

TAX ASPECTS OF THE REORGANIZATION 

   At least one but not more than 20 business days prior to the Valuation 
Date, High Income will declare and pay a dividend or dividends which, 
together with all previous such dividends, will have the effect of 
distributing to Shareholders all of High Income's investment company taxable 
income for all periods since inception of High Income through and including 
the Valuation Date (computed without regard to any dividends paid deduction), 
and all of High Income's net capital gain, if any, realized in such periods 
(after reduction for any capital loss carry-forward). 

   The Reorganization is intended to qualify for Federal income tax purposes 
as a tax-free reorganization under Section 368(a)(1) of the Internal Revenue 
Code of 1986, as amended (the "Code"). High Income and High Yield have 
represented that, to their best knowledge, there is no plan or intention by 
Shareholders to redeem, sell, exchange or otherwise dispose of a number of 
High Yield Shares received in the transaction that would reduce Shareholders' 
ownership of High Yield Shares to a number of shares having a value, as of 
the Closing Date, of less than 50% of the value of all of the formerly 
outstanding High Income shares as of the same date. High Income and High 
Yield have each further represented that, as of the Closing Date, High Income 
and High Yield will qualify as regulated investment companies. 

   As a condition to the Reorganization, High Income and High Yield will 
receive an opinion of Gordon Altman Butowsky Weitzen Shalov & Wein that, 
based on certain assumptions, facts, the terms of the Reorganization 
Agreement and additional representations set forth in the Reorganization 
Agreement or provided by High Income and High Yield: 

   1. The transfer of substantially all of High Income's assets in exchange 
for the High Yield Shares and the assumption by High Yield of certain stated 
liabilities of High Income followed by the distribution by High Income of the 
High Yield Shares to Shareholders in exchange for their High Income shares 
will constitute a "reorganization" within the meaning of Section 368(a)(1) of 
the Code, and High Income and High Yield will each be a "party to a 
reorganization" within the meaning of Section 368 (b) of the Code; 

   2. No gain or loss will be recognized by High Yield upon the receipt of 
the assets of High Income solely in exchange for the High Yield Shares and 
the assumption by High Yield of the stated liabilities of High Income; 

   3. No gain or loss will be recognized by High Income upon the transfer of 
the assets of High Income to High Yield in exchange for the High Yield Shares 
and the assumption by High Yield of the stated liabilities or upon the 
distribution of High Yield Shares to Shareholders in exchange for their High 
Income shares; 

   4. No gain or loss will be recognized by Shareholders upon the exchange of 
the shares of High Income for the High Yield Shares; 

   5. The aggregate tax basis for the High Yield Shares received by each of 
the Shareholders pursuant to the reorganization will be the same as the 
aggregate tax basis of the shares in High Income held by each such 
Shareholder immediately prior to the reorganization; 

                               14           
<PAGE>
   6. The holding period of the High Yield Shares to be received by each 
Shareholder will include the period during which the shares in High Income 
surrendered in exchange therefor were held (provided such shares in High 
Income were held as capital assets on the date of the Reorganization); 

   7. The tax basis of the assets of High Income acquired by High Yield will 
be the same as the tax basis of such assets to High Income immediately prior 
to the Reorganization; and 

   8. The holding period of the assets of High Income in the hands of High 
Yield will include the period during which those assets were held by High 
Income. 

   The Reorganization will result in a "change of ownership" of High Yield 
under Section 382 of the Code. High Yield has a capital loss carryover of 
approximately $937 million and a net unrealized loss of $    as of        . 
Under the provisions of Section 382 of the Code, the full amount of those 
built-in-losses and capital loss carryovers will not be available to offset 
realized capital gains of the combined fund after the Reorganization. Only a 
portion of the unrealized capital losses and capital loss carryovers (i.e., 
approximately $27 million per year for eight years) will be available to 
offset realized net capital gains of the combined fund. After eight years, 
the unused loss carryover will be eliminated. The Board has considered this 
limitation on the use of High Yield's capital loss carryforwards that would 
result from the Reorganization (see "The Board's Consideration"). 

   SHAREHOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE EFFECT, IF 
ANY, OF THE PROPOSED TRANSACTION IN LIGHT OF THEIR INDIVIDUAL CIRCUMSTANCES. 
BECAUSE THE FOREGOING DISCUSSION ONLY RELATES TO THE FEDERAL INCOME TAX 
CONSEQUENCES OF THE PROPOSED TRANSACTION, SHAREHOLDERS SHOULD ALSO CONSULT 
THEIR TAX ADVISORS AS TO STATE AND LOCAL TAX CONSEQUENCES, IF ANY, OF THE 
PROPOSED TRANSACTION. 

DESCRIPTION OF SHARES 

   Class B Shares of High Yield to be issued pursuant to the Reorganization 
Agreement will, when issued, be fully paid and non-assessable by High Yield 
and transferable without restrictions and will have no preemptive rights. As 
discussed above, Class B shares of High Yield also have a conversion feature 
pursuant to which approximately ten (10) years after the date of the original 
purchase of such shares, the shares will convert automatically to Class A 
Shares, based on the relative net asset values of the two classes. For 
greater details regarding the conversion feature, including the method by 
which the 10 year period is calculated and the treatment of reinvested 
dividends, see "Purchase of Fund Shares" in High Yield's Prospectus attached 
hereto.

        COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS 

INVESTMENT OBJECTIVES AND POLICIES 

   High Income and High Yield have identical investment objectives, which is 
primarily to seek a high level of current income, and, as a secondary 
objective, to seek capital appreciation (but only when consistent with the 
primary objective). High Yield seeks to achieve its investment objective by 
investing principally (under normal circumstances at least 65% of its total 
assets) in fixed-income securities rated Baa or lower by Moody's, or BBB or 
lower by Standard & Poor's. High Income also seeks to achieve its investment 
objective by investing principally in fixed income securities; however, High 
Income's fixed income securities are rated Ba or lower by Moody's, or BB or 
lower by Standard & Poor's. Neither fund has any minimum quality rating 
standard for its investments. Both funds also consider non-rated securities 
for investment when the Investment Manager believes that the financial 
conditions of the issuers of such securities, or the protection afforded by 
the terms of the securities themselves, make them appropriate investments of 
the funds. With respect to High Income, the fund seeks to maintain under 
normal circumstances a dollar weighted average maturity of between five and 
ten years. High Yield does not have a specific policy as to the portfolio's 
dollar weighted average maturity. 

   Up to 35% of each fund's total assets may, under normal conditions, be 
invested in securities other than the fixed-income securities described, 
including, among other securities, common stocks (in the case of High Yield, 
up to 20% of the fund's total assets), U.S. Government Obligations (including 
zero coupon securities), repurchase agreements, and futures contracts and 
related options thereon. Up to 35% of High Income's total assets may, under 
normal conditions, be invested in securities of foreign issuers; whereas High 
Yield may invest only up to 20% of its total assets in fixed-income 
securities issued by foreign governments and other foreign issuers and in 
foreign currency issues of domestic issuers, but not more than 10% of its 
total assets in such securities, whether issued by a foreign or domestic 
issuer, which are denominated in foreign currency. High Income also is 
specifically authorized to enter into forward foreign currency exchange 
contracts as a hedge against fluctuations in future foreign exchange rates. 

   Both High Yield and High Income may invest part or all of their respective 
assets in money market instruments to maintain temporarily a "defensive" 
posture when, in the opinion of the Investment Manager, it is advisable to do 
so because of market conditions. 

   High Income may purchase and sell (write) listed options on portfolio 
securities or on the U.S. Dollar or foreign currencies and may write covered 
call options on such securities, without limit, in order to hedge against the 
decline in the value of a security or currency in which such security is 
denominated, to earn additional income and or to close out long call option 
positions. High Income also may purchase listed and over-the-counter call and 
put options in amounts equaling up to 5% of its total assets. High Income may 
purchase call and put options to close out covered call or written put 
positions, as applicable, or to protect the value of the relevant security. 
High Yield, however, may purchase or sell (write) listed options only on debt 
securities as a means of achieving additional return or of hedging the value 
of the 

                               16           
<PAGE>
fund's portfolio. High Income fund may only write covered options which are 
listed on national securities exchanges, the total amount of which may not 
exceed 20% of the fund's total assets. High Income has an overall limitation 
that it may not purchase options if, as a result, the aggregate cost of all 
outstanding options exceeds 10% of the fund's total assets. 

   High Income may purchase and sell U.S. and foreign exchange-traded futures 
contracts on portfolio securities, on foreign currencies, on U.S. and foreign 
fixed-income securities and on index securities or securities indexes, for 
hedging purposes. High Yield, however, may only purchase and sell financial 
futures contracts and related options thereon as a hedge against changes in 
interest rates. Both funds may purchase and sell options on eligible futures 
contracts for hedging purposes or to close out an opposite position. 

   Both High Yield and High Income may (i) purchase securities on a 
when-issued or delayed delivery basis, (ii) purchase or sell securities on a 
forward commitment basis and (iii) purchase securities on a "when, as and if 
issued" basis. High Income may invest in warrants and stock rights attached 
to other portfolio securities, without limit, and it may invest up to 5% of 
its net assets in other warrants. By contrast, High Yield has a 5% limitation 
as to investments in all warrants. Both funds may enter into repurchase 
agreements subject to certain procedures designed to minimize risks 
associated with such agreements. However, only High Income is authorized to 
enter into reverse repurchase agreements and dollar rolls. High Income may 
invest up to 10% of its total assets in securities which are subject to 
restrictions on resale because they have not been registered under the 
Securities Act of 1933, or which are otherwise not readily marketable; 
whereas, High Yield has a 5% limit respecting investments in such securities. 

   The investment policies of both High Income and High Yield are not 
fundamental and may be changed by their respective Boards. The foregoing 
discussion is a summary of the principal differences and similarities between 
the investment policies of the funds. For a more complete discussion of each 
fund's policies see "Investment Objectives and Policies" in each fund's 
respective Prospectus and "Investment Practices and Policies" in each fund's 
respective Statement of Additional Information. 

INVESTMENT RESTRICTIONS 

   The investment restrictions adopted by High Income and High Yield as 
fundamental are substantially similar and are summarized under the caption 
"Investment Restrictions" in their respective Prospectuses and Statements of 
Additional Information. A fundamental investment restriction cannot be 
changed without the vote of a majority of the outstanding voting securities 
of a fund, as defined in the 1940 Act. The material differences are as 
follows. High Yield has a fundamental restriction that it may not invest more 
than 5% of the value of its total assets in the securities of any one issuer 
(other than obligations issued or guaranteed by the U.S. Government, its 
agencies or instrumentalities), whereas High Income is subject to a similar 
fundamental limitation only with respect to 75% of its total assets. High 
Yield has a fundamental restriction that it may not purchase more than 10% of 
the voting securities, or more than 10% of any class of securities of any one 
issuer, whereas High Income is subject to a similar limitation with respect 
to only 75% of its total assets. 

   In addition, High Yield has a fundamental restriction that it may not 
acquire common stocks in excess of 20% of its total assets, whereas High 
Income does not have any such policy. 

                               17           
<PAGE>
   High Yield has a fundamental restriction that it may not write, purchase 
or sell puts, calls, or combinations thereof except options on futures 
contacts or options on debt securities, whereas High Income has no similar 
limitation. In addition, both funds, as a matter of fundamental policy, may 
not purchase securities of other investment companies, except in connection 
with a merger, consolidation, reorganization or acquisition of assets; 
however, High Income carves out an additional exception for purchases made in 
accordance with Section 12(d) of the 1940 Act. 

   Finally, High Yield has a fundamental restriction that it may not invest 
in securities of any issuer if, to the knowledge of such fund, any officer, 
or 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 
directors who own more than 1/2 of 1% own in the aggregate more than 5% of 
the outstanding securities of such issuer; whereas, High Income is subject to 
such limitation on a non-fundamental basis.

                     AGREEMENT AND PLAN OF REORGANIZATION 

   THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is made as of this 
30th day of June, 1997, by and between DEAN WITTER HIGH YIELD SECURITIES 
INC., a Maryland Corporation ("High Yield") and DEAN WITTER HIGH INCOME 
SECURITIES, a Massachusetts business trust ("High Income"). 

   This Agreement is intended to be and is adopted as a "plan of 
reorganization" within the meaning of Treas. Reg. 1.368-2(g), for a 
reorganization under Section 368(a) (1) of the Internal Revenue Code of 1986, 
as amended (the "Code"). The reorganization ("Reorganization") will consist 
of the transfer to High Yield of substantially all of the assets of High 
Income in exchange for the assumption by High Yield of all stated liabilities 
of High Income and the issuance by High Yield of Class B shares of common 
stock ("High Yield Shares"), to be distributed, after the Closing Date 
hereinafter referred to, to the shareholders of High Income in liquidation of 
High Income as provided herein, all upon the terms and conditions hereinafter 
set forth in this Agreement. 

   In consideration of the premises and of the covenants and agreements 
hereinafter set forth, the parties hereto covenant and agree as follows: 

1. THE REORGANIZATION AND LIQUIDATION OF HIGH INCOME 

   1.1 Subject to the terms and conditions herein set forth and on the basis 
of the representations and warranties contained herein, High Income agrees to 
assign, deliver and otherwise transfer the High Income Assets (as defined in 
paragraph 1.2) to High Yield and High Yield agrees in exchange therefor to 
assume all of High Income's stated liabilities on the Closing Date as set 
forth in paragraph 1.3(a) and to deliver to High Income the number of High 
Yield Shares, including fractional High Yield Shares, determined by dividing 
the value of the High Income Assets, net of such stated liabilities, computed 
as of the Valuation Date (as defined in paragraph 2.1) in the manner set 
forth in paragraph 2.1, by the net asset value of a High Yield Share, 
computed at the time and date and in the manner set forth in paragraph 2.2. 
Such transactions shall take place at the closing provided for in paragraph 
3.1 ("Closing"). 

   1.2 (a) The "High Income Assets" shall consist of all property, including 
without limitation, all cash (other than the "Cash Reserve" (as defined in 
paragraph 1.3(b)), cash equivalents, securities and dividend and interest 
receivables owned by High Income, and any deferred or prepaid expenses shown 
as an asset on High Income's books on the Valuation Date. 

       (b) On or prior to the Valuation Date, High Income will provide High 
Yield with a list of all of High Income's assets to be assigned, delivered 
and otherwise transferred to High Yield and of the stated liabilities to be 
assumed by High Yield pursuant to this Agreement. High Income reserves the 
right to sell any of the securities on such list but will not, without the 
prior approval of High Yield, acquire any additional securities other than 
securities of the type in which High Yield is permitted to invest and in 
amounts agreed to in writing by High Yield. High Yield will, within a 
reasonable time prior to the Valuation Date, furnish High Income with a 
statement of High Yield's investment objectives, policies and restrictions 
and a list of the securities, if any, on the list referred to in the first 
sentence of this paragraph that do not conform to High Yield's investment 
objective, policies and restrictions. In the event that High 

                               A-1           
<PAGE>
Income holds any investments that High Yield is not permitted to hold, High 
Income will dispose of such securities on or prior to the Valuation Date. In 
addition, if it is determined that the portfolios of High Income and High 
Yield, when aggregated, would contain investments exceeding certain 
percentage limitations imposed upon High Yield with respect to such 
investments, High Income if requested by High Yield will, on or prior to the 
Valuation Date, dispose of and/or reinvest a sufficient amount of such 
investments as may be necessary to avoid violating such limitations as of the 
Closing Date (as defined in paragraph 3.1). 

   1.3 (a) High Income will endeavor to discharge all of its liabilities and 
obligations on or prior to the Valuation Date. High Yield will assume all 
stated liabilities, which includes, without limitation, all expenses, costs, 
charges and reserves reflected on an unaudited Statement of Assets and 
Liabilities of High Income prepared by the Treasurer of High Income as of the 
Valuation Date in accordance with generally accepted accounting principles 
consistently applied from the prior audited period. 

       (b) On the Valuation Date, High Income may establish a cash reserve, 
which shall not exceed 5% of High Income's net assets as of the close of 
business on the Valuation Date ("Cash Reserve") to be retained by High Income 
and used for the payment of its liabilities not discharged prior to the 
Valuation Date and for the expenses of dissolution. 

   1.4 In order for High Income to comply with Section 852(a)(1) of the Code 
and to avoid having any investment company taxable income or net capital gain 
(as defined in Sections 852(b)(2) and 1222(11) of the Code, respectively) in 
the short taxable year ending with its dissolution, High Income will on or 
before the Valuation Date (a) declare a dividend in an amount large enough so 
that it will have declared dividends of all of its investment company taxable 
income and net capital gain, if any, for such taxable year (determined 
without regard to any deduction for dividends paid) and (b) distribute such 
dividend. 

   1.5 On the Closing Date or as soon as practicable thereafter, High Income 
will distribute High Yield Shares received by High Income pursuant to 
paragraph 1.1 pro rata to its shareholders of record determined as of the 
close of business on the Valuation Date ("High Income Shareholders"). Such 
distribution will be accomplished by an instruction, signed by High Income's 
Secretary, to transfer High Yield Shares then credited to High Income's 
account on the books of High Yield to open accounts on the books of High 
Yield in the names of the High Income Shareholders and representing the 
respective pro rata number of High Yield Shares due such High Income 
Shareholders. All issued and outstanding shares of High Income simultaneously 
will be canceled on High Income's books; however, share certificates 
representing interests in High Income will represent a number of High Yield 
Shares after the Closing Date as determined in accordance with paragraph 2.3. 
High Yield will issue certificates representing High Yield Shares in 
connection with such exchange only upon the written request of a High Income 
Shareholder. 

   1.6 Ownership of High Yield Shares will be shown on the books of High 
Yield's transfer agent. High Yield Shares will be issued in the manner 
described in High Yield's current Prospectus and Statement of Additional 
Information. 

   1.7 Any transfer taxes payable upon issuance of High Yield Shares in a 
name other than the registered holder of High Yield Shares on High Income's 
books as of the close of business on the Valuation Date shall, as a condition 
of such issuance and transfer, be paid by the person to whom High Yield 
Shares are to be issued and transferred. 

                               A-2           
<PAGE>
    1.8 Any reporting responsibility of High Income is and shall remain the 
responsibility of High Income up to and including the date on which High 
Income is dissolved and deregistered pursuant to paragraph 1.9. 

   1.9 Within one year after the Closing Date, High Income shall pay or make 
provision for the payment of all its liabilities and taxes, and distribute to 
the shareholders of High Income as of the close of business on the Valuation 
Date any remaining amount of the Cash Reserve (as reduced by the estimated 
cost of distributing it to shareholders). High Income shall be dissolved as a 
Massachusetts business trust and deregistered as an investment company under 
the Investment Company Act of 1940, as amended ("1940 Act"), promptly 
following the making of all distributions pursuant to paragraph 1.5. 

   1.10 Copies of all books and records maintained on behalf of High Income 
in connection with its obligations under the 1940 Act, the Code, state blue 
sky laws or otherwise in connection with this Agreement will promptly after 
the Closing be delivered to officers of High Yield or their designee and High 
Yield or its designee shall comply with applicable record retention 
requirements to which High Income is subject under the 1940 Act. 

2. VALUATION 

   2.1 The value of the High Income Assets shall be the value of such assets 
computed as of 4:00 p.m. New York City time on the third day that the New 
York Stock Exchange is open for business following the receipt of the 
requisite approval by shareholders of High Income of this Agreement or at 
such time on such earlier or later date after such approval as may be 
mutually agreed upon in writing (such time and date being hereinafter called 
the "Valuation Date"), using the valuation procedures set forth in High 
Yield's then current Prospectus and Statement of Additional Information. 

   2.2 The net asset value of a High Yield Share shall be the net asset value 
per share computed on the Valuation Date, using the valuation procedures set 
forth in High Yield's then current Prospectus and Statement of Additional 
Information. 

   2.3 The number of High Yield Shares (including fractional shares, if any) 
to be issued hereunder shall be determined by dividing the value of the High 
Income Assets, net of the liabilities of High Income assumed by High Yield 
pursuant to paragraph 1.1, determined in accordance with paragraph 2.1, by 
the net asset value of a High Yield Share determined in accordance with 
paragraph 2.2. 

   2.4 All computations of value shall be made by Dean Witter Services 
Company Inc. ("Services") in accordance with its regular practice in pricing 
High Yield. High Yield shall cause Services to deliver a copy of its 
valuation report at the Closing. 

3. CLOSING AND CLOSING DATE 

   3.1 The Closing shall take place on the next business day following the 
Valuation Date (the "Closing Date"). The Closing shall be held as of 9:00 
a.m. Eastern time, or at such other time as the parties may agree. The 
Closing shall be held in a location mutually agreeable to the parties hereto. 
All acts taking place at the Closing shall be deemed to take place 
simultaneously as of 9:00 a.m. Eastern time on the Closing Date unless 
otherwise provided. 

   3.2 Portfolio securities held by High Income and represented by a 
certificate or other written instrument shall be presented by it or on its 
behalf to The Bank of New York (the "Custodian"), as 

                               A-3           
<PAGE>
custodian for High Yield, for examination no later than five business days 
preceding the Valuation Date. Such portfolio securities (together with any 
cash or other assets) shall be delivered by High Income to the Custodian for 
the account of High Yield on or before the Closing Date in conformity with 
applicable custody provisions under the 1940 Act and duly endorsed in proper 
form for transfer in such condition as to constitute good delivery thereof in 
accordance with the custom of brokers. The portfolio securities shall be 
accompanied by all necessary federal and state stock transfer stamps or a 
check for the appropriate purchase price of such stamps. Portfolio securities 
and instruments deposited with a securities depository (as defined in Rule 
17f-4 under the 1940 Act) shall be delivered on or before the Closing Date by 
book-entry in accordance with customary practices of such depository and the 
Custodian. The cash delivered shall be in the form of a Federal Funds wire, 
payable to the order of "The Bank of New York, Custodian for Dean Witter High 
Yield Securities Inc." 

   3.3 In the event that on the Valuation Date, (a) the New York Stock 
Exchange shall be closed to trading or trading thereon shall be restricted or 
(b) trading or the reporting of trading on such Exchange or elsewhere shall 
be disrupted so that, in the judgment of both High Yield and High Income, 
accurate appraisal of the value of the net assets of High Yield or the High 
Income Assets is impracticable, the Valuation Date shall be postponed until 
the first business day after the day when trading shall have been fully 
resumed without restriction or disruption and reporting shall have been 
restored. 

   3.4 If requested, High Income shall deliver to High Yield or its designee 
(a) at the Closing, a list, certified by its Secretary, of the names,

owned by each such High Income Shareholder, all as of the Valuation Date, and 
(b) as soon as practicable after the Closing, all original documentation 
(including Internal Revenue Service forms, certificates, certifications and 
correspondence) relating to the High Income Shareholders' taxpayer 
identification numbers and their liability for or exemption from back-up 
withholding. High Yield shall issue and deliver to such Secretary a 
confirmation evidencing delivery of High Yield Shares to be credited on the 
Closing Date to High Income or provide evidence satisfactory to High Income 
that such High Yield Shares have been credited to High Income's account on 
the books of High Yield. At the Closing, each party shall deliver to the 
other such bills of sale, checks, assignments, share certificates, if any, 
receipts or other documents as such other party or its counsel may reasonably 
request.

    the transactions contemplated hereby will not, violate High Income's 
    Declaration of Trust or By-Laws; and (e) to the knowledge of such counsel, 
    no consent, approval, authorization or order of any court or governmental 
    authority of the United States or any state is required for the

     (f) The holding period of High Yield Shares to be received by each High 
    Income Shareholder will include the period during which the High Income 
    Shares surrendered in exchange therefor were held (provided such High 
    Income Shares were held as capital assets on the date of the 
    Reorganization); 

     (g) The tax basis of the assets of High Income acquired by High Yield 
    will be the same as the tax basis of such assets to High Income

              PROSPECTUS
              JULY 28, 1997
              Dean Witter High Yield Securities Inc. (the "Fund") is an 
open-end diversified management investment company whose primary investment 
objective is to earn a high level of current income. As a secondary objective,
the Fund will seek capital appreciation, but only when consistent with its 
primary objective. The Fund seeks high current income by investing principally
in fixed-income securities which are rated in the lower categories by 
established rating services (Baa or lower by Moody's Investors Service, Inc. 
or BBB or lower by Standard & Poor's Corporation) or are non-rated securities 
of comparable quality.

               INVESTORS SHOULD CAREFULLY CONSIDER THE RELATIVE RISKS, INCLUDING
THE RISK OF DEFAULT, OF INVESTING IN HIGH YIELD SECURITIES, WHICH ARE COMMONLY
KNOWN AS JUNK BONDS. BONDS OF THIS TYPE ARE CONSIDERED TO BE SPECULATIVE WITH
REGARD TO THE PAYMENT OF INTEREST AND RETURN OF PRINCIPAL. INVESTORS SHOULD ALSO
BE COGNIZANT OF THE FACT THAT SUCH SECURITIES ARE NOT GENERALLY MEANT FOR SHORT-
TERM INVESTING AND SHOULD ASSESS THE RISKS ASSOCIATED WITH AN INVESTMENT IN THE
FUND. (See "Investment Objectives and Policies.")
 

               The Fund offers four classes of shares (each, a "Class"), each
with a different combination of sales charges, ongoing fees and other features.
The different distribution arrangements permit an investor to choose the method
of purchasing shares that the investor believes is most beneficial given the
amount of the purchase, the length of time the investor expects to hold the
shares and other relevant circumstances. Shares of the Fund held prior to July
28, 1997 have been designated Class D shares. (See "Purchase of Fund
Shares--Alternative Purchase Arrangements.")

 

               This Prospectus sets forth concisely the information you should
know before investing in the Fund. It should be read and retained for future
reference. Additional information about the Fund is contained in the Statement
of Additional Information, dated July 28, 1997, which has been filed with the
Securities and Exchange Commission, and which is available at no charge upon
request of the Fund at the address or telephone numbers listed on this page. The

- -------------------------------------------------------------------------------

Investment        Dean Witter InterCapital Inc., the Investment Manager of the

- -------------------------------------------------------------------------------

Management        The monthly fee is at an annual rate of 1/2 of 1% of average
Fee               daily net assets, scaled down on assets over $500 million
                  (see page 7).

- -------------------------------------------------------------------------------

Distributor       Dean Witter Distributors Inc. (the "Distributor"). The Fund
and               has adopted a distribution plan pursuant and to Rule 12b-1
Distribution      under the Investment Company Act (the "12b-1 Plan") with

                  Class A, Class B and Class C shares of the Fund to the
                  Distributor. The entire Fee 12b-1 fee payable by Class A and a
                  portion of the 12b-1 fee payable by each of Class B and Class
                  C equal to 0.20% of the average daily net assets of Class B
                  and 0.25% of the average daily net assets of Class C are
                  currently each characterized as a service fee within the
                  meaning of the National Association of Securities Dealers,
                  Inc. guidelines. The remaining portion of the 12b-1 fee, if
                  any, is characterized as an asset-based sales charge (see
                  pages 14 and 23).

- -------------------------------------------------------------------------------

Alternative       Four classes of shares are offered: 
Purchase     
Arrangements      o Class A shares are offered with a front-end sales charge,
                  starting at 4.25% and reduced for larger purchases.
                  Investments of $1 million or more (and investments by certain
                  other limited categories of investors) are not subject to any
                  sales charge at the time of purchase but a contingent deferred
                  sales charge ("CDSC") of 1.0% may be imposed on redemptions
                  within one year of purchase. The Fund is authorized to
                  reimburse the Distributor for specific expenses incurred in
                  promoting the distribution of the Fund's Class A shares and
                  servicing shareholder accounts pursuant to the Fund's 12b-1
                  Plan. Reimbursement may in no event exceed an amount equal to
                  payments at an annual rate of 0.25% of average daily net
                  assets of the Class (see pages 14, 17 and 23).

- --------------------------------------------------------------------------------
                  o Class B shares are offered without a front-end sales charge,
                  but will in most cases be subject to a CDSC (scaled down from
                  5.0% to 1.0%) if redeemed within six years after purchase. The
                  CDSC will be imposed on any redemption of shares if after such
                  redemption the aggregate current value of a Class B account
                  with the Fund falls below the aggregate amount of the
                  investor's purchase payments made during the six years
                  preceding the redemption. A different CDSC schedule applies to
                  investments by certain qualified plans. Class B shares are
                  also subject to a 12b-1 fee assessed at the annual rate of
                  0.75% of the average daily net assets of Class B. Class B
                  shares convert to Class A shares approximately ten years after
                  the date of the original purchase (see pages 14, 20 and 23). 

                  o Class C shares are offered without a front-end sales charge,
                  but will in most cases be subject to a CDSC of 1.0% if
                  redeemed within one year after purchase. The Fund is
                  authorized to reimburse the Distributor for specific expenses
                  incurred in promoting the distribution of the Fund's Class C
                  shares and servicing shareholder accounts pursuant to the
                  Fund's 12b-1 Plan. Reimbursement may in no event exceed an
                  amount equal to payments at an annual rate of 0.85% of average
                  daily net assets of the Class (see pages 14, 22 and 23). 

                  o Class D shares are offered only to investors meeting an
                  initial investment minimum of $5 million and to certain other
                  limited categories of investors. Class D shares are offered
                  without a front-end sales charge or CDSC and are not subject
                  to any 12b-1 fee (see pages 14, 22 and 23. All shares of the
                  Fund held prior to July 28, 1997 have been designated Class D
                  shares. Additional investments in Class D shares by
                  shareholders holding such shares may only be made if those
                  shareholders are otherwise eligible to purchase Class D
                  shares. However, shareholders holding such shares will receive
                  the benefit of the value of such shares towards reduced sales
                  charges on purchases of Class A shares pursuant to the Fund's
                  "Right of Accumulation" (see page 18).
- -------------------------------------------------------------------------------
Dividends         Dividends from net investment income are declared and paid
and               monthly; distributions from net capital gains, if any, are
Capital Gains     paid at least annually. The Fund may, however, determine to
Distributions     retain all or part of any net long-term capital gains in any
                  year for reinvestment. Dividends and capital gains
                  distributions paid on shares of a Class are automatically
                  reinvested in additional shares of the same Class at net asset
                  value unless the shareholder elects to receive cash. Shares
                  acquired by dividend and distribution reinvestment will not be
                  subject to any sales charge or CDSC (see pages 25 and 29).
- -------------------------------------------------------------------------------
Redemption        Shares are redeemable by the shareholder at net asset value
                  less any applicable CDSC on Class A, Class B or Class C
                  shares. An account may be involuntarily redeemed if the total
                  value of the account is less than $100 or, if the account was
                  opened through EasyInvest(SM), if after twelve months the
                  shareholder has invested less than $1,000 in the account (see
                  page 28).
- -------------------------------------------------------------------------------
Risks             The net asset value of the Fund's shares will fluctuate with
                  changes in the market value of its portfolio securities. The
                  Fund's yield will also vary based on the yield of the Fund's
                  portfolio securities. Compared with higher rated, lower
                  yielding fixed-income securities, portfolio securities of the
                  Fund may be subject to greater risk of loss of income and
                  principal, including the risk of default, and greater risk of
                  increases and decreases in net asset value due to market
                  fluctuations. The Fund may purchase foreign securities,
                  when-issued and delayed delivery and when, as and if issued
                  securities and other securities subject to repurchase
                  agreements which involve certain special risks. The Fund may
                  purchase common stock which is exchangeable for fixed-income
                  securities in circumstances involving takeovers or
                  recapitalizations. The Fund may also invest in futures and
                  options which may be considered speculative in nature and may
                  involve greater risks than those customarily assumed by
                  certain other investment companies which do not invest in such
                  instruments. Investors should review the investment objectives
                  and policies of the Fund carefully and consider their ability
                  to assume the risks involved in purchasing shares of the Fund
                  (see pages 7-14).
- -------------------------------------------------------------------------------
  The above is qualified in its entirety by the detailed information appearing
  elsewhere in the Prospectus and the Statement of Additional Information.

</TABLE>

- ------------

(1) Reduced for purchases of $25,000 and over (see "Purchase of FUND
    Shares--Initial Sales Charge Alternative--Class A Shares").

 

(2) Investments that are not subject to any sales charge at the time of purchase
    are subject to a CDSC of 1.00% that will be imposed on redemptions made
    within one year after purchase, except for certain specific circumstances
    (see "Purchase of Fund Shares--Initial Sales Charge Alternative--Class A
    Shares").

(3) The CDSC is scaled down annually to 1.00% during the sixth year, reaching
    zero thereafter.

(4) Only applicable to redemptions made within one year after purchase (see
    "Purchase of Fund Shares--Level Load Alternative--Class C Shares").

(5) The 12b-1 fee is accrued daily and payable monthly. The entire 12b-1 fee
    payable by Class A and a portion of the 12b-1 fee payable by each of Class B
    and Class C equal to 0.20% of the average daily net assets of Class B and
    0.25% of the average daily net assets of Class C are currently each
    characterized as a service fee within the meaning of National Association of
    Securities Dealers, Inc. ("NASD") guidelines and are payments made for
    personal service and/or maintenance of shareholder accounts. The remainder
    of the 12b-1 fee, if any, is an asset-based sales charge, and is a
    distribution fee paid to the Distributor to compensate it for the services
    provided and the expenses borne by the Distributor and others in the
    distribution of the Fund's shares (see "Purchase of Fund Shares--Plan of
    Distribution").

(6) Upon conversion of Class B shares to Class A shares, such shares will be
    subject to the lower 12b-1 fee applicable to Class A Shares. No sales charge
    is imposed at the time of conversion of Class B Shares to Class A shares.
    Class C shares do not have a conversion feature and, therefore, are subject
    to an ongoing 0.85% distribution fee (see "Purchase of Fund
    Shares--Alternative Purchase Arrangements").

(7) There were no outstanding shares of Class A, Class B or Class C prior to the
    date of this Prospectus. Accordingly, "Total Fund Operating Expenses," as
    shown above with respect to those Classes, are based upon the sum of 12b-1
    Fees, Management Fees and estimated "Other Expenses."

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean Witter High Yield Securities Inc. (the "Fund") is an open-end
diversified management investment company incorporated in Maryland on June 14,
1979.
 

    Dean Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager. The Investment Manager, which was incorporated in July,
1992, is a wholly-owned subsidiary of Morgan Stanley, Dean Witter, Discover &
Co., a preeminent global financial services firm that maintains leading market
positions in each of its three primary businesses--securities, asset management
and credit services.

 

    InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to 100 investment companies, thirty of which are
listed on the New York Stock Exchange, with combined total assets of
approximately $    billion as of June 30, 1997. The Investment Manager also
manages, and advises managers of, common stock portfolios of pension plans,
other institutions and individuals which aggregated approximately $    billion
at such date.

 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.
 
    The Fund's Board of Directors reviews the various services provided by or
under the direction of the Investment Manager to ensure that the Fund's general
investment policies and programs are being properly carried out and that
administrative services are being provided to the Fund in a satisfactory manner.
 
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily by applying a
percentage rate to the daily net assets of the Fund which declines as net assets
of the Fund reach levels over $500 million (up to $3 billion). For the fiscal
year ended August 31, 1996, the Fund accrued total compensation to the
Investment Manager amounting to 0.50% of the Fund's average daily net assets and
the Fund's total expenses amounted to 0.66% of the Fund's average daily net
assets.
 
INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
 
    The primary investment objective of the Fund is to earn a high level of
current income. As a secondary objective, the Fund will seek capital
appreciation, but only when consistent with its primary objective. Capital
appreciation may result, for example, from an improvement in the credit standing
of an issuer whose securities are held in the Fund's portfolio or from a general
decline in interest rates, or a combination of both. Conversely, capital
depreciation may result, for example, from a lowered credit standing or a
general rise in interest rates, or a combination of both. There is no assurance
that the objectives will be achieved.

    The higher yields sought by the Fund are generally obtainable from
securities rated in the lower categories by recognized rating services. The Fund
seeks high current income by investing principally in fixed-income securities
rated Baa or lower by Moody's Investors Service, Inc. ("Moody's"), or BBB or
lower by Standard & Poor's Corporation ("Standard & Poor's"). Fixed-income
securities rated Baa by Moody's or BBB by Standard & Poor's
 
                                       7
<PAGE>

have speculative characteristics greater than those of more highly rated bonds,
while fixed-income securities rated Ba or BB or lower by Moody's and Standard &
Poor's, respectively, are considered to be speculative investments. Furthermore,
the Fund does not have any minimum quality rating standard for its investments.
As such, the Fund may invest in securities rated as low as Caa, Ca or C by
Moody's or CCC, CC, C or C1 by Standard & Poor's. Fixed-income securities rated
Caa or Ca by Moody's may already be in default on payment of interest or
principal, while bonds rated C by Moody's, their lowest bond rating, can be
regarded as having extremely poor prospects of ever attaining any real
investment standing. Bonds rated C1 by Standard & Poor's, their lowest bond
rating, are no longer making interest payments. For a further discussion of the
characteristics and risks associated with high yield securities, see "Special
Investment Considerations" below. A description of corporate bond ratings is
contained in the Appendix.
 
    Non-rated securities will also be considered for investment by the Fund when
the Investment Manager believes that the financial condition of the issuers of
such securities, or the protection afforded by the terms of the securities
themselves, makes them appropriate investments for the Fund.
 
    In circumstances where the Investment Manager determines that investment in
municipal obligations would facilitate the Fund's ability to accomplish its
investment objectives, it may invest up to 10% of its total assets in such
obligations, including municipal bonds issued at a discount.
 
    All fixed-income securities are subject to two types of risks: the credit
risk and the interest rate risk. The credit risk relates to the ability of the
issuer to meet interest or principal payments or both as they come due.
Generally, higher yielding bonds are subject to a credit risk to a greater
extent than higher quality bonds. The interest rate risk refers to the
fluctuations in net asset value of any portfolio of fixed-income securities
resulting solely from the inverse relationship between price and yield of
fixed-income securities; that is, when the general level of interest rates
rises, the prices of outstanding fixed-income securities generally decline, and
when interest rates fall, prices generally rise.
 
    The ratings of fixed-income securities by Moody's and Standard & Poor's are
a generally accepted barometer of credit risk. However, as the creditworthiness
of issuers of lower-rated fixed-income securities is more problematical than
that of issuers of higher-rated fixed-income securities, the achievement of the
Fund's investment objective will be more dependent upon the Investment Manager's
own credit analysis than would be the case with a mutual fund investing
primarily in higher quality bonds. The Investment Manager will utilize a
security's credit rating as simply one indication of an issuer's
creditworthiness and will principally rely upon its own analysis of any security
currently held by the Fund or potentially purchasable by the Fund for its
portfolio.
 
    In determining which securities to purchase or hold for the Fund's portfolio
and in seeking to reduce credit and interest rate risks, the Investment Manager
will rely on information from various sources, including: the rating of the
security; research, analysis and appraisals of brokers and dealers, including
DWR; the views of the Fund's directors and others regarding economic
developments and interest rate trends; and the Investment Manager's own analysis
of factors it deems relevant. The extent to which the Investment Manager is
successful in reducing depreciation or losses arising from either interest rate
or credit risks depends in part on the Investment Manager's portfolio management
skills and judgment in evaluating the factors affecting the value of securities.
No assurance can be given regarding the degree of success that will be achieved.
 
SPECIAL RISK CONSIDERATIONS
 

    The net asset value of the Fund's shares will fluctuate with changes in the
market value of its portfolio securities. The Fund's yield will also vary based
on the yield of the Fund's portfolio securities.

 
                                       8
<PAGE>

    Because of the special nature of the Fund's investment in high yield
securities, commonly known as junk bonds, the Investment Manager must take
account of certain special considerations in assessing the risks associated with
such investments. Although the growth of the high yield securities market in the
1980s had paralleled a long economic expansion, recently many issuers have been
affected by adverse economic and market conditions. It should be recognized that
an economic downturn or increase in interest rates is likely to have a negative
effect on the high yield bond market and on the value of the high yield
securities held by the Fund, as well as on the ability of the securities'
issuers to repay principal and interest on their borrowings.
 
    The prices of high yield securities have been found to be less sensitive to
changes in prevailing interest rates than higher-rated investments, but are
likely to be more sensitive to adverse economic changes or individual corporate
developments. During an economic downturn or substantial period of rising
interest rates, highly leveraged issuers may experience financial stress which
would adversely affect their ability to service their principal and interest
payment obligations, to meet their projected business goals or to obtain
additional financing. If the issuer of a fixed-income security owned by the Fund
defaults, the Fund may incur additional expenses to seek recovery. In addition,
periods of economic uncertainty and change can be expected to result in an
increased volatility of market prices of high yield securities and a concomitant
volatility in the net asset value of a share of the Fund. Moreover, the market
prices of certain of the Fund's portfolio securities which are structured as
zero coupon and payment-in-kind securities are affected to a greater extent by
interest rate changes and thereby tend to be more volatile than securities which
pay interest periodically and in cash (see "Dividends, Distributions and Taxes"
for a discussion of the tax ramifications of investments in such securities).
 
    The secondary market for high yield securities may be less liquid than the
markets for higher quality securities and, as such, may have an adverse effect
on the market prices of certain securities. The limited liquidity of the market
may also adversely affect the ability of the Fund's Directors to arrive at a
fair value for certain high yield securities at certain times and could make it
difficult for the Fund to sell certain securities. In addition, new laws and
potential new laws may have an adverse effect upon the value of high yield
securities and a concomitant negative impact upon the net asset value of a share
of the Fund.
 
    During the fiscal year ended August 31, 1996, the monthly dollar weighted
average ratings of the debt obligations held by the Fund, expressed as a
percentage of the Fund's total investments, were as follows:
 

<TABLE>

  Unrated                             6.0%
</TABLE>

 
    Consistent with its primary investment objective, the Fund anticipates that,
under normal conditions, at least 65% of the value of its total assets will be
invested in the lower-rated and non-rated fixed-income securities previously
described. However, when the difference between yields derived from such
securities and those derived from higher rated issues are relatively narrow, the
Fund may invest in the higher rated issues since they may provide similar yields
with somewhat less risk. Fixed-income securities appropriate for the Fund may
include both convertible and nonconvertible debt securities and preferred stock.
 
    Pending investment of proceeds from the sale of shares of the Fund or of its
portfolio securities or
 
                                       9
<PAGE>

at other times when market conditions dictate a more "defensive" investment
strategy, the Fund may invest without limit in money market instruments,
including commercial paper of corporations organized under the laws of any state
or political subdivision of the United States, certificates of deposit, bankers'
acceptances and other obligations of domestic banks or domestic branches of
foreign banks, or foreign branches of domestic banks, in each case having total
assets of at least $500 million, and obligations issued or guaranteed by the
United States Government (including zero coupon securities), or foreign
governments or their respective instrumentalities or agencies. The yield on
these securities will generally tend to be lower than the yield on other
securities to be purchased by the Fund. To the extent the Fund purchases
Eurodollar certificates of deposit issued by foreign branches of domestic United
States banks, consideration will be given to their domestic marketability, the
lower reserve requirements normally mandated for overseas banking operations,
the possible impact of interruptions in the flow of international currency
transactions and economic developments which might adversely affect the payment
of principal or interest.
 
    Public Utilities.  The Fund's investments in public utilities, if any, may
be subject to certain risks incurred by the Fund due to Federal, State or
municipal regulatory changes, insufficient rate increases or cost overruns.
 
    Repurchase Agreements.  The Fund may enter into repurchase agreements, which
may be viewed as a type of secured lending by the Fund, and which typically
involve the acquisition by the Fund of debt securities, from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security at a specified price and at
a fixed time in the future, usually not more than seven days from the date of
purchase. While repurchase agreements involve certain risks not associated with
direct investments in debt securities, including the risk of default or
bankruptcy of the selling institution, the Fund follows procedures designed to
minimize such risks.
 
    When-Issued and Delayed Delivery Securities. 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 transaction. These
securities are subject to market fluctuation and no interest accrues to the
purchaser prior to settlement. At the time the Fund makes the commitment to
purchase such securities, it will record the transaction and thereafter reflect
the value, each day, of such security in determining its net asset value. 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.
 
    When, as and if Issued Securities.  The Fund may purchase securities on a
"when, as and if issued" basis under which the issuance of the security depends
upon the occurrence of a subsequent event, such as approval of a merger,
corporate reorganization, leveraged buyout or debt restructuring. If the
anticipated event does not occur and the securities are not issued, the Fund
will have lost an investment opportunity. There is no overall limit on the
percentage of the Fund's assets which may be committed to the purchase of
securities on a "when, as and if issued" basis. An increase in the percentage of
the Fund's assets committed to the purchase of securities on a "when, as and if
issued" basis may increase the volatility of its net asset value.
 
    Foreign Securities.  The Fund may invest up to 20% of its total assets in
fixed-income securities issued by foreign governments and other foreign issuers
and in foreign currency issues of domestic issuers, but not more than 10% of its
total assets in such securities, whether issued by a foreign or domestic issuer,
which are denominated in foreign currency. Foreign securities investments may be
affected by changes in currency rates or exchange
 
                                       10
<PAGE>

control regulations, changes in governmental administration or economic or
monetary policy (in the United States and abroad) or changed circumstances in
dealings between nations. Costs will be incurred in connection with conversions
between various currencies held by the Fund.
 
    Investments in foreign securities will also occasion risks relating to
political and economic developments abroad, including the possibility of
expropriations or confiscatory taxation, limitations on the use or transfer of
Fund assets and any effects of foreign social, economic or political
instability. Foreign companies are not subject to the regulatory requirements of
U.S. companies and, as such, there may be less publicly available information
about such companies. Moreover, foreign companies are not subject to uniform
accounting, auditing and financial reporting standards and requirements
comparable to those applicable to U.S. companies. Finally, in the event of a
default of any foreign debt obligations, it may be more difficult for the Fund
to obtain or enforce a judgment against the issuers of such securities.
 
    Securities of foreign issuers may be less liquid than comparable securities
of U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their American
counterparts. Brokerage commissions, dealer concessions and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of the Fund's trades effected in such markets. As such, the
inability to dispose of portfolio securities due to settlement delays could
result in losses to the Fund due to subsequent declines in value of such
securities and the inability of the Fund to make intended security purchases due
to settlement problems could result in a failure of the Fund to make potentially
advantageous investments.
 

    Common Stocks.  The Fund may invest in common stocks in an amount up to 20%
of its total assets. The Fund may directly purchase common stocks on the open
market. In addition, the Fund may acquire common stocks when they are included
in a unit with fixed-income securities purchased by the Fund; when fixed-income
securities held by the Fund are converted to equity issues; when the Fund
exercises a warrant; and when the Fund purchases the common stock of companies
involved in takeovers or recapitalizations, where the issuer or a stockholder
has offered, or pursuant to a "going private" transaction is effecting, a
transaction involving the issuance of newly issued fixed-income securities to
the holders of such common stock.

 

    The prices of common stock are generally more volatile than those of
fixed-income securities. Moreover, not all common stock pay dividends and those
that do generally pay lower amounts than most fixed-income securities. The Fund
will only purchase common stocks directly when the Investment Manager believes
that their purchase will assist the Fund in meeting its investment objectives.

 
    Zero Coupon Securities.  A portion of the fixed-income securities purchased
by the Fund may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive their
full value at maturity. The interest earned on such securities is, implicitly,
automatically compounded and paid out at maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest if prevailing interest rates decline, the owner of a zero coupon
security will be unable to participate in higher yields upon reinvestment of
interest received on interest-paying securities if prevailing interest rates
rise.
 
    A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will not
receive current cash available for distribution to shareholders. In addition,
zero coupon securities
 
                                       11
<PAGE>

are subject to substantially greater price fluctuations during periods of
changing prevailing interest rates than are comparable securities which pay
interest on a current basis. Current federal tax law requires that a holder
(such as the Fund) of a zero coupon security accrue a portion of the discount at
which the security was purchased as income each year even though the Fund
receives no interest payments in cash on the security during the year.
 
    Futures Contracts and Options on Futures. The Fund may invest in financial
futures contracts ("futures contracts") and related options thereon. The Fund
may sell a futures contract or a call option thereon or purchase a put option on
such futures contract, if the Investment Manager anticipates interest rates to
rise, as a hedge against a decrease in the value of the Fund's portfolio
securities. If the Investment Manager anticipates that interest rates will
decline, the Fund may purchase a futures contract or a call option thereon or
sell a put option on such futures contract to protect against an increase in the
price of the securities the Fund intends to purchase. These futures contracts
and related options thereon will be used only as a hedge against anticipated
interest rate changes.
 
    The Fund may not enter into futures contracts or purchase related options
thereon if immediately thereafter the amount committed to margin plus the amount
paid for premiums for unexpired options on futures contracts exceeds 5% of the
value of the Fund's total assets. The Fund may not purchase or sell futures
contracts or related options thereon if, immediately thereafter, more than
one-third of its net assets would be hedged.
 
    Options.  The Fund may purchase or sell (write) listed options on debt
securities as a means of achieving additional return or of hedging the value of
the Fund's portfolio. The Fund may only write covered options which are listed
on national securities exchanges. The Fund may not write covered options in an
amount exceeding 20% of the value of its total assets. The Fund may only buy
options which are listed on national securities exchanges. The Fund will not
purchase options if, as a result, the aggregate cost of all outstanding options
exceeds 10% of the Fund's total assets.
 
    For a discussion of futures and options, including the risks of such
transactions, see the Statement of Additional Information.
 
    Private Placements.  The Fund may invest up to 5% of its total assets in
securities which are subject to restrictions on resale because they have not
been registered under the Securities Act of 1933, as amended (the "Securities
Act"), or which are otherwise not readily marketable. (See "Investment
Restrictions" in the Statement of Additional Information.) These securities are
generally referred to as private placements or restricted securities.
Limitations on the resale of such securities may have an adverse effect on their
marketability, and may prevent the Fund from disposing of them promptly at
reasonable prices. The Fund may have to bear the expense of registering such
securities for resale and the risk of substantial delays in effecting such
registration.
 

    The Securities and Exchange Commission has adopted Rule 144A under the
Securities Act, which permits the Fund to sell restricted securities to
qualified institutional buyers without limitation. The Investment Manager,
pursuant to procedures adopted by the Board of Directors of the Fund, will make
a determination as to the liquidity of each restricted security purchased by the
Fund. If a restricted security is determined to be "liquid," such security will
not be considered to be "restricted" for purposes of the above-disclosed 5%
limitation and will not be included within the category "illiquid securities,"
which under current policy may not exceed 15% of the Fund's total assets.
However, investing in Rule 144A securities could have the effect of increasing
the level of Fund illiquidity to the extent the Fund, at a particular point of
time, may be unable to find qualified institutional buyers interested in
purchasing such securities.

PORTFOLIO MANAGEMENT
 

    The Fund is actively managed by the Investment Manager with a view to
achieving the Fund's investment objective. The Fund is managed within
InterCapital's Taxable Income Group, which managed approximately $    billion in
assets at June 30, 1997. Peter M. Avelar, Senior Vice President of InterCapital
and a member of InterCapital's Taxable Fixed-Income Group, has been the primary
portfolio manager of the Fund since January, 1991 and has been managing fixed
portfolios consisting of fixed-income and equity securities at InterCapital for
over five years.

 

    Securities purchased by the Fund are, generally, sold by dealers acting as
principal for their own accounts. Pursuant to an order issued by the Securities
and Exchange Commission, the Fund may effect principal transactions in certain
money market instruments with Dean Witter Reynolds Inc. ("DWR") and other
broker-dealer affiliates of InterCapital. In addition, the Fund may incur
brokerage commissions on transactions conducted through DWR and other brokers
and dealers that are affiliates of InterCapital.

 
    Although the Fund does not intend to engage in substantial short-term
trading, it may sell portfolio securities without regard to the length of time
that they have been held, in order to take advantage of new investment
opportunities or yield differentials, or because the Fund desires to preserve
gains or limit losses due to changing economic conditions, interest rate trends,
or the financial condition of the issuer. The Fund's portfolio turnover rate for
the fiscal year ended August 31, 1996 was 49%. The Fund will incur underwriting
discount costs (on underwritten securities) and brokerage costs commensurate
with its portfolio turnover rate. Short term gains and losses may result from
such portfolio transactions. See "Dividends, Distributions and Taxes" for a
discussion of the tax implications of the Fund's trading policy.
 
    Except as otherwise noted, all investment policies and practices discussed
above are not fundamental policies of the Fund and, as such may be changed
without shareholder approval.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions that
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund, as defined in the Act.
 
    The Fund may not:
 
   1. Acquire common stocks in excess of 20% of its total assets.
 
   2. Invest more than 5% of its total assets in the securities of any one
issuer (other than obligations of, or guaranteed by, the United States
Government, its agencies or instrumentalities).
 
   3. Purchase more than 10% of the voting securities, or more than 10% of any
class of securities, of any issuer. For purposes of this restriction, all
outstanding debt securities of an issuer are considered as one class and all
preferred stocks of an issuer are considered as one class.
 
   4. Invest more than 25% of its total assets in securities of issuers in any
one industry. For purposes of this restriction, gas, electric, water and
telephone utilities will each be treated as being a separate industry. This
restriction does not apply to obligations issued or guaranteed by the United
States Government or its agencies or instrumentalities.
 
   5. Invest more than 5% of its total assets in securities of companies having
a record, together with predecessors, of less than three years of continuous
operation. This restriction shall not apply to any obligation of the United
States Government, its agencies or instrumentalities.
 
                                       13

<PAGE>

    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.

 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 

GENERAL

 

    The Fund offers each class of its shares for sale to the public on a
continuous basis. Pursuant to a Distribution Agreement between the Fund and Dean
Witter Distributors Inc. (the "Distributor"), an affiliate of the Investment
Manager, shares of the Fund are distributed by the Distributor and offered by
DWR and other dealers who have entered into agreements with the Distributor
("Selected Broker-Dealers"). The principal executive office of the Distributor
is located at Two World Trade Center, New York, New York 10048.

 

    The Fund offers four classes of shares (each, a "Class"). 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 for certain specific circumstances. Class B
shares are sold without an initial sales charge but are subject to a CDSC
(scaled down from 5.0% to 1.0%) payable upon most redemptions within six years
after purchase. (Class B shares purchased by certain qualified
employer-sponsored benefit plans are subject to a CDSC scaled down from 2.0% to
1.0% if redeemed within three years after purchase.) Class C shares are sold
without an initial sales charge but are subject to a CDSC of 1.0% on most
redemptions made within one year after purchase. Class D shares are sold without
an initial sales charge or CDSC and are available only to investors meeting an
initial investment minimum of $5 million, and to certain other limited
categories of investors. At the discretion of the Board of Trustees of the Fund,
Class A shares may be sold to categories of investors in addition to those set
forth in this prospectus at net asset value without a front-end sales charge,
and Class D shares may be sold to certain other categories of investors, in each
case as may be described in the then current prospectus of the Fund. See
"Alternative Purchase Arrangements--Selecting a Particular Class" for a
discussion of factors to consider in selecting which Class of shares to
purchase.

 

    The minimum initial purchase is $1,000 for each Class of shares, although
Class D shares are only available to persons investing $5 million or more and to
certain other limited categories of investors. For the purpose of meeting the
minimum $5 million initial investment for Class D shares, and subject to the
$1,000 minimum initial investment for each Class of the Fund, an investor's
existing holdings of Class A shares of the Fund and other Dean Witter Funds that
are multiple class funds ("Dean Witter Multi-Class Funds") and shares of Dean
Witter Funds sold with a front-end sales charge ("FSC Funds") and concurrent
investments in Class D shares of the Fund and other Dean Witter Multi-Class
Funds will be aggregated. Subsequent purchases of $100 or more may be made by
sending a check, payable to Dean Witter High Yield Securities Inc., directly to
Dean Witter Trust Company (the "Transfer Agent") at P.O. Box 1040, Jersey City,
N.J. 07303 or by contacting an account executive of DWR or other Selected
Broker-Dealer. When purchasing shares of the Fund, investors must specify
whether the purchase is for Class A, Class B, Class C or Class D shares. If no
Class is specified, the Transfer Agent will not process the transaction until
the proper Class is identified. The minimum initial purchase in the case of
investments through EasyInvest(SM), an automatic purchase plan (see "Shareholder
Services"), is $100, provided that the schedule of automatic investments will
result in investments totalling at least $1,000 within the first twelve months.
In the case of purchases made pursuant to Systematic Payroll Deduction

 
                                       14
<PAGE>


plans (including Individual Retirement plans), the Fund, in its discretion, may
accept such Purchases without regard to any minimum amounts which would
otherwise be required if the Fund has reason to believe that additional
purchases will increase the amount of the purchase of shares in all accounts
under such plans to at least $1,000. Certificates for shares purchased will not
be issued unless a request is made by the shareholder in writing to the Transfer
Agent.

 

    Shares are sold through the Distributor on a normal three business day
settlement basis; that is, payment is due on the third business day (settlement
date) after the order is placed with the Distributor. Since DWR and other
Selected Broker-Dealers forward investors' funds on settlement date, they will
benefit from the temporary use of the funds if payment is made prior thereto. As
noted above, orders placed directly with the Transfer Agent must be accompanied
by payment. Investors will be entitled to receive income dividends and capital
gains distributions if their order is received by the close of business on the
day prior to the record date for such dividends and distributions. Sales
personnel of a Selected Broker-Dealer are compensated for selling shares of the
Fund by the Distributor or any of its affiliates and/or the Selected
Broker-Dealer. In addition, some sales personnel of the Selected Broker-Dealer
will receive various types of non-cash compensation as special sales incentives,
including trips, educational and/or business seminars and merchandise. The Fund
and the Distributor reserve the right to reject any purchase order.

 

    Analogous Dean Witter Funds.  The Distributor and the Investment Manager
serve in the same capacities for Dean Witter High Income Securities, an open-end
investment company with investment objectives and policies similar to those of
the Fund. Shares of Dean Witter High Income Securities are offered to the public
at net asset value, with a CDSC assessed upon redemptions within five years of
purchase, as well as an annual Rule 12b-1 distribution fee. The Classes of the
Fund and Dean Witter High Income Securities have differing fees and expenses,
which will affect performance. Investors who would like to receive a prospectus
for Dean Witter High Income Securities should call the telephone numbers listed
on the front cover of this Prospectus, or may call their account executive for
additional information.

 

    The Board of Directors of the Fund and the Board of Trustees of Dean Witter
High Income Securities have approved a reorganization plan whereby Dean Witter
High Income Securities would be merged into the Fund. This plan is subject to
the consent of the Dean Witter High Income Securities shareholders. If approved,
the Funds' assets would be combined and Dean Witter High Income Securities
shareholders would become shareholders of the Fund, receiving Class B shares of
the Fund equal to the value of their holdings in Dean Witter High Income
Securities. A proxy statement formally detailing the proposal will be
distributed to Dean Witter High Income Securities shareholders in August 1997.

 

ALTERNATIVE PURCHASE ARRANGEMENTS

 

    The Fund offers several Classes of shares to investors designed to provide
them with the flexibility of selecting an investment best suited to their needs.
The general public is offered three Classes of shares: Class A shares, Class B
shares and Class C shares, which differ principally in terms of sales charges
and rate of expenses to which they are subject. A fourth Class of shares, Class
D shares, is offered only to limited categories of investors (see "No Load
Alternative--Class D Shares" below).

 

    Each Class A, Class B, Class C or Class D share of the Fund represents an
identical interest in the investment portfolio of the Fund except that Class A,
Class B and Class C shares bear the expenses of the ongoing shareholder service
fees, Class B and Class C shares bear the expenses of

 
                                       15

<PAGE>

the ongoing distribution fees and Class A, Class B and Class C shares which are
redeemed subject to a CDSC bear the expense of the additional incremental
distribution costs resulting from the CDSC applicable to shares of those
Classes. The ongoing distribution fees that are imposed on Class A, Class B and
Class C shares will be imposed directly against those Classes and not against
all assets of the Fund and, accordingly, such charges against one Class will not
affect the net asset value of any other Class or have any impact on investors
choosing another sales charge option. See "Plan of Distribution" and
"Redemptions and Repurchases."

 

    Set forth below is a summary of the differences between the Classes and the
factors an investor should consider when selecting a particular Class. This
summary is qualified in its entirety by detailed discussion of each Class that
follows this summary.

 

    Class A Shares.  Class A shares are sold at net asset value plus an initial
sales charge of up to 4.25%. The initial sales charge is reduced for certain
purchases. Investments of $1 million or more (and investments by certain other
limited categories of investors) are not subject to any sales charges at the
time of purchase but are subject to a CDSC of 1.0% on redemptions made within
one year after purchase, except for certain specific circumstances. Class A
shares are also subject to a 12b-1 fee of up to 0.25% of the average daily net
assets of the Class. See "Initial Sales Charge Alternative--Class A Shares."

 

    Class B Shares.  Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. (Class B shares purchased by certain
qualified employer-sponsored benefit plans are subject to a CDSC scaled down
from 2.0% to 1.0% if redeemed within three years after purchase.) This CDSC may
be waived for certain redemptions. Class B shares are also subject to an annual
12b-1 fee of 0.75% of the average daily net assets of Class B. The Class B 
shares' distribution fee will cause that Class to have higher expenses and pay 
lower dividends than Class A or Class D shares.



    After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition, a
certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time. See
"Contingent Deferred Sales Charge Alternative--Class B Shares."

 

    Class C Shares.  Class C shares are sold at net asset value with no initial
sales charge but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They are
subject to an annual 12b-1 fee of up to 0.85% of the average daily net assets of
the Class C shares. The Class C shares' distribution fee may cause that Class to
have higher expenses and pay lower dividends than Class A or Class D shares. See
"Level Load Alternative--Class C Shares."

 

    Class D Shares.  Class D shares are available only to limited categories of
investors (see "No Load Alternative--Class D Shares" below). Class D shares are
sold at net asset value with no initial sales charge or CDSC. They are not
subject to any 12b-1 fees. See "No Load Alternative--Class D Shares."

 

    Selecting A Particular Class.  In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any other
relevant facts and circumstances:

 

    The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for significantly reduced or, in

 
                                       16

<PAGE>

the case of purchases of $1 million or more, no initial sales charges may find
Class A shares particularly attractive because similar sales charge reductions
are not available with respect to Class B or Class C shares. Moreover, Class A
shares are subject to lower ongoing expenses than are Class B or Class C shares
over the term of the investment. As an alternative, Class B and Class C shares
are sold without any initial sales charge so the entire purchase price is
immediately invested in the Fund. Any investment return on these additional 
investment amounts may partially or wholly offset the higher annual expenses 
of these Classes. Because the Fund's future return cannot be predicted, 
however, there can be no assurance that this would be the case.

 

    Finally, investors should consider the effect of the CDSC period and any
conversion rights of the Classes in the context of their own investment time
frame. For example, although Class C shares are subject to a significantly lower
CDSC upon redemptions, they do not, unlike Class B shares, convert into Class A
shares after approximately ten years, and, therefore, are subject to an ongoing
12b-1 fee of 0.85% (rather than the 0.25% fee applicable to Class A shares) for
an indefinite period of time. Thus, Class B shares may be more attractive than
Class C shares to investors with longer term investment outlooks. Other
investors, however, may elect to purchase Class C shares if, for example, they
determine that they do not wish to be subject to a front-end sales charge and
they are uncertain as to the length of time they intend to hold their shares.

 

    For the purpose of meeting the $5 million minimum investment amount for
Class D shares, holdings of Class A shares in all Dean Witter Multi-Class Funds,
shares of FSC Funds and shares of Dean Witter Funds for which such shares have
been exchanged will be included together with the current investment amount.

 

    Sales personnel may receive different compensation for selling each Class of
shares. Investors should understand that the purpose of a CDSC is the same as
that of the initial sales charge in that the sales charges applicable to each
Class provide for the financing of the distribution of shares of that Class.

 

    Set forth below is a chart comparing the sales charge, 12b-1 fees and
conversion options applicable to each Class of shares:

other differences between the Classes of shares.

 

INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES

 

    Class A shares are sold at net asset value plus an initial sales charge. In
some cases, reduced sales charges may be available, as described below.
Investments of $1 million or more (and investments by certain other limited
categories of investors) are not subject to any sales charges at

 
                                       17
<PAGE>


the time of purchase but are subject to a CDSC of 1.0% on redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased), except for certain specific circumstances. The
CDSC will be assessed on an amount equal to the lesser of the current market
value or the cost of the shares being redeemed. The CDSC will not be imposed (i)
in the circumstances set forth below in the section "Contingent Deferred Sales
Charge Alternative--Class B Shares--CDSC Waivers," except that the references to
six years in the first paragraph of that section shall mean one year in the case
of Class A shares, and (ii) in the circumstances identified in the section
"Additional Net Asset Value Purchase Options" below. Class A shares are also
subject to an annual 12b-1 fee of up to 0.25% of the average daily net assets of
the Class.

 

    The offering price of Class A shares will be the net asset value per share
next determined following receipt of an order (see "Determination of Net Asset
Value" below), plus a sales charge (expressed as a percentage of the offering
price) on a single transaction as shown in the following table:

    Upon notice to all Selected Broker-Dealers, the Distributor may reallow up
to the full applicable sales charge as shown in the above schedule during
periods specified in such notice. During periods when 90% or more of the sales
charge is reallowed, such Selected Broker-Dealers may be deemed to be
underwriters as that term is defined in the Securities Act of 1933.

 

    The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or her
spouse and their children under the age of 21 purchasing shares for his, her or
their own accounts; (c) a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account; (d) a pension, profit-sharing
or other employee benefit plan qualified or non-qualified under Section 401 of
the Internal Revenue Code; (e) tax-exempt organizations enumerated in Section
501(c)(3) or (13) of the Internal Revenue Code; (f) employee benefit plans
qualified under Section 401 of the Internal Revenue Code of a single employer or
of employers who are "affiliated persons" of each other within the meaning of
Section 2(a)(3)(c) of the Act; and for investments in Individual Retirement
Accounts of employees of a single employer through Systematic Payroll Deduction
plans; or (g) any other organized group of persons, whether incorporated or not,
provided the organization has been in existence for at least six months and has
some purpose other than the purchase of redeemable securities of a registered
investment company at a discount.

 

    Combined Purchase Privilege.  Investors may have the benefit of reduced
sales charges in accordance with the above schedule by combining purchases of
Class A shares of the Fund in single transactions with the purchase of Class A
shares of other Dean Witter Multi-Class Funds and shares of FSC Funds. The sales
charge payable on the purchase of the Class A shares of the Fund, the Class A
shares of the other Dean Witter Multi-Class Funds and the shares of the FSC
Funds will be at their respective rates applicable to the total amount of the
combined concurrent purchases of such shares.

 

    Right of Accumulation.  The above persons and entities may benefit from a
reduction of the sales charges in accordance with the above schedule if the
cumulative net asset value of Class A shares purchased in a single transaction,
together with shares of the Fund and other Dean Witter Funds previously
purchased at a price including a

 
                                       18

<PAGE>

front-end sales charge (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), which are held at
the time of such transaction, amounts to $25,000 or more. If such investor has a
cumulative net asset value of shares of FSC Funds and Class A and Class D shares
equal to at least $5 million, such investor is eligible to purchase Class D
shares subject to the $1,000 minimum initial investment requirement of that
Class of the Fund. See "No Load Alternative--Class D Shares" below.

 

    The Distributor must be notified by DWR or a 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 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 Selected Broker-Dealer or the Transfer Agent fails to confirm the
investor's represented holdings.

 

    Letter of Intent.  The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of Class A shares of the Fund
from DWR or other Selected Broker-Dealers. The cost of Class A shares of the
Fund or shares of other Dean Witter Funds which were previously purchased at a
price including a front-end sales charge during the 90-day period prior to the
date of receipt by the Distributor of the Letter of Intent, or of Class A shares
of the Fund or shares of other Dean Witter Funds acquired in exchange for shares
of such funds purchased during such period at a price including a front-end
sales charge, which are still owned by the shareholder, may also be included in
determining the applicable reduction.

 

    Additional Net Asset Value Purchase Options. In addition to investments of
$1 million or more, Class A shares also may be purchased at net asset value by
the following:

 

   (1) trusts for which Dean Witter Trust Company ("DWTC") or Dean Witter Trust
FSB ("DWTFSB") (each of which is an affiliate of the Investment Manager)
provides discretionary trustee services;

 

   (2) persons participating in a fee-based program approved by the Distributor,
pursuant to which such persons pay an asset based fee for services in the nature
of investment advisory or administrative services (such investments are subject
to all of the terms and conditions of such programs, which may include
termination fees and restrictions on transferability of Fund shares);

 

   (3) retirement plans qualified under Section 401(k) of the Internal Revenue
Code ("401(k) plans") and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code with at least 200 eligible employees and for
which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services Group of
DWR serves as recordkeeper;

 

   (4) 401(k) plans and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code for which DWTC or DWTFSB serves as Trustee
or the 401(k) Support Services Group of DWR serves as recordkeeper whose Class B
shares have converted to Class A shares, regardless of the plan's asset size or
number of eligible employees;

 

   (5) investors who are clients of a Dean Witter account executive who joined
Dean Witter from another investment firm within six months prior to the date of
purchase of Fund shares by such investors, if the shares are being purchased
with the proceeds from a redemption of shares of an open-end proprietary mutual
fund of the account executive's previous firm which imposed either a front-end
or deferred sales charge, provided such purchase was made within sixty days
after the redemption and the proceeds of the redemption had been maintained in
the interim in cash or a money market fund; and

 

   (6) other categories of investors, at the discretion of the Board, as
disclosed in the then current prospectus of the Fund.

 
                                       19

    No CDSC will be imposed on redemptions of shares purchased pursuant to
paragraphs (1), (2) or (5), above.

DWR or another Selected Broker-Dealer or consult the Statement of Additional
Information.

 

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES

 

    Class B shares are sold at net asset value next determined without an
initial sales charge so that the full amount of an investor's purchase payment
may be immediately invested in the Fund. A CDSC, however, will be imposed on
most Class B shares redeemed within six years after purchase. The CDSC will be
imposed on any redemption of shares if after such redemption the aggregate
current value of a Class B account with the Fund falls below the aggregate
amount of the investor's purchase payments for Class B shares made during the
six years (or, in the case of shares held by certain employer-sponsored benefit
plans, three years) preceding the redemption. In addition, Class B shares are
subject to an annual 12b-1 fee of 0.75% of the the average daily net assets of
Class B.

 

    Except as noted below, Class B shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in which
the shares were purchased) will not be subject to any CDSC upon redemption.
Shares redeemed earlier than six years after purchase may, however, be subject
to a CDSC which will be a percentage of the dollar amount of shares redeemed and
will be assessed on an amount equal to the lesser of the current market value or
the cost of the shares being redeemed. The size of this percentage will depend
upon how long the shares have been held, as set forth in the following table:

 



           YEAR SINCE                     CDSC AS A
            PURCHASE                    PERCENTAGE OF
          PAYMENT MADE                 AMOUNT REDEEMED
- ---------------------------------  -----------------------
                                
First............................              5.0%
Second...........................              4.0%
Third............................              3.0%
Fourth...........................              2.0%
Fifth............................              2.0%
Sixth............................              1.0%
Seventh and thereafter...........              None


 

    In the case of Class B shares of the Fund held by 401(k) plans or other
employer-sponsored plans qualified under Section 401(a) of the Internal Revenue
Code for which DWTC or DWTFSB serves as Trustee or the 401(k) Support Services
Group of DWR serves as recordkeeper and whose accounts are opened on or after
July 28, 1997, shares held for three years or more after purchase (calculated as
described in the paragraph above) will not be subject to any CDSC upon
redemption. However, shares redeemed earlier than three years after purchase may
be subject to a CDSC (calculated as described in the paragraph above), the
percentage of which will depend on how long the shares have been held, as set
forth in the following table:

 



           YEAR SINCE
            PURCHASE               CDSC AS A PERCENTAGE OF
          PAYMENT MADE                 AMOUNT REDEEMED
- ---------------------------------  -----------------------
                                
First............................              2.0%
Second...........................              2.0%
Third............................              1.0%
Fourth and thereafter............              None


 

    CDSC Waivers.  A CDSC will not be imposed on: (i) any amount which
represents an increase in value of shares purchased within the six years (or, in
the case of shares held by certain employer-sponsored benefit plans, three
years) preceding the redemption; (ii) 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; and
(iii) the current net asset value of shares purchased through reinvestment of
dividends or distributions and/or shares acquired in exchange for shares of FSC
Funds or of other Dean Witter Funds acquired in exchange for such shares.
Moreover, in determining whether a CDSC is applicable it will be assumed that
amounts described in (i), (ii) and (iii) above (in that order) are redeemed
first.

 

    In addition, the CDSC, if otherwise applicable, will be waived in the case
of:

 

   (1) redemptions of shares held at the time a shareholder dies or becomes
disabled, only if the shares are:  (A) registered either in the name of an
individual shareholder (not a trust), or in the names

 
                                       20

<PAGE>

of such shareholder and his or her spouse as joint tenants with right of
survivorship; or  (B) held in a qualified corporate or self-employed retirement
plan, Individual Retirement Account ("IRA") or Custodial Account under Section
403(b)(7) of the Internal Revenue Code ("403(b) Custodial Account"), provided in
either case that the redemption is requested within one year of the death or
initial determination of disability;

 

   (2) redemptions in connection with the following retirement plan
distributions:  (A) lump-sum or other distributions from a qualified corporate
or self-employed retirement plan following retirement (or, in the case of a "key
employee" of a "top heavy" plan, following attainment of age 59 1/2); (B)
distributions from an IRA or 403(b) Custodial Account following attainment of
age 59 1/2; or  (C) a tax-free return of an excess contribution to an IRA; and

 

   (3) all redemptions of shares held for the benefit of a participant in a
401(k) plan or other employer-sponsored plan qualified under Section 401(a) of
the Internal Revenue Code which offers investment companies managed by the
Investment Manager or its subsidiary, Dean Witter Services Company Inc., as 
self-directed investment alternatives and for which DWTC or DWTFSB serves as 
Trustee or the 401(k) Support Services Group of DWR serves as recordkeeper ("
Eligible Plan"), provided that either:  (a) the plan continues to be an 
Eligible Plan after the redemption; or  (b) the redemption is in connection 
with the complete termination of the plan involving the distribution of all 
plan assets to participants.

 

    With reference to (1) above, for the purpose of determining disability, the
Distributor utilizes the definition of disability contained in Section 72(m)(7)
of the Internal Revenue Code, which relates to the inability to engage in
gainful employment. With reference to (2) above, the term "distribution" does
not encompass a direct transfer of IRA, 403(b) Custodial Account or retirement
plan assets to a successor custodian or trustee. All waivers will be granted
only following receipt by the Distributor of confirmation of the shareholder's
entitlement.

 

    Conversion To Class A Shares.  Class B shares will convert automatically to
Class A shares, based on the relative net asset values of the shares of the two
Classes on the conversion date, which will be approximately ten (10) years after
the date of the original purchase. The ten year period is calculated from the
last day of the month in which the shares were purchased or, in the case of
Class B shares acquired through an exchange or a series of exchanges, from the
last day of the month in which the original Class B shares were purchased. The
conversion of shares will take place in the month following the tenth
anniversary of the purchase. There will also be converted at that time such
proportion of Class B shares acquired through automatic reinvestment of
dividends and distributions owned by the shareholder as the total number of his
or her Class B shares converting at the time bears to the total number of
outstanding Class B shares purchased and owned by the shareholder. In the case
of Class B shares held by a 401(k) plan or other employer-sponsored plan
qualified under Section 401(a) of the Internal Revenue Code and for which DWTC
or DWTFSB serves as Trustee or the 401(k) Support Services Group of DWR serves
as recordkeeper, the plan is treated as a single investor and all Class B shares
will convert to Class A shares on the conversion date of the first shares of a
Dean Witter Multi-Class Fund purchased by that plan. In the case of Class B
shares previously exchanged for shares of an "Exchange Fund" (see "Shareholder
Services--Exchange Privilege"), the period of time the shares were held in the
Exchange Fund (calculated from the last day of the month in which the Exchange
Fund shares were acquired) is excluded from the holding period for conversion.
If those shares are subsequently re-exchanged for Class B shares of a Dean
Witter Multi-Class Fund, the holding period resumes on the last day of the month
in which Class B shares are reacquired.

 
                                       21

<PAGE>

    If a shareholder has received share certificates for Class B shares, such
certificates must be delivered to the Transfer Agent at least one week prior to
the date for conversion. Class B shares evidenced by share certificates that are
not received by the Transfer Agent at least one week prior to any conversion
date will be converted into Class A shares on the next scheduled conversion date
after such certificates are received.

 

    Effectiveness of the conversion feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel that (i) the conversion of shares does not constitute a taxable event
under the Internal Revenue Code, (ii) Class A shares received on conversion will
have a basis equal to the shareholder's basis in the converted Class B shares
immediately prior to the conversion, and (iii) Class A shares received on
conversion will have a holding period that includes the holding period of the
converted Class B shares. The conversion feature may be suspended if the ruling
or opinion is no longer available. In such event, Class B shares would continue
to be subject to Class B 12b-1 fees.

 

LEVEL LOAD ALTERNATIVE--CLASS C SHARES

 

    Class C shares are sold at net asset value next determined without an
initial sales charge but are subject to a CDSC of 1.0% on most redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased). The CDSC will be assessed on an amount equal
to the lesser of the current market value or the cost of the shares being
redeemed. The CDSC will not be imposed in the circumstances set forth above in
the section "Contingent Deferred Sales Charge Alternative--Class B Shares--CDSC
Waivers," except that the references to six years in the first paragraph of that
section shall mean one year in the case of Class C shares. Class C shares are
subject to an annual 12b-1 fee of up to 0.85% of the average daily net assets of
the Class. Unlike Class B shares, Class C shares have no conversion feature and,
accordingly, an investor that purchases Class C shares will be subject to 12b-1
fees applicable to Class C shares for an indefinite period subject to annual
approval by the Fund's Board of Trustees and regulatory limitations.

 

NO LOAD ALTERNATIVE--CLASS D SHARES

 

    Class D shares are offered without any sales charge on purchase or
redemption and without any 12b-1 fee. Class D shares are offered only to
investors meeting an initial investment minimum of $5 million and the following
categories of investors: (i) investors participating in the InterCapital mutual
fund asset allocation program pursuant to which such persons pay an asset based
fee; (ii) persons participating in a fee-based program approved by the
Distributor, pursuant to which such persons pay an asset based fee for services
in the nature of investment advisory or administrative services (subject to all
of the terms and conditions of such programs, which may include termination fees
and restrictions on transferability of Fund shares); (iii) 401(k) plans
established by DWR and SPS Transaction Services, Inc. (an affiliate of DWR) for
their employees; (iv) certain Unit Investment Trusts sponsored by DWR; (v)
certain other open-end investment companies whose shares are distributed by the
Distributor; and (vi) other categories of investors, at the discretion of the
Board, as disclosed in the then current prospectus of the Fund. All shares of
the Fund held prior to July 28, 1997 have been designated Class D shares.
Additional investments in Class D shares by shareholders holding such shares may
only be made if those shareholders are otherwise eligible to purchase Class D
shares. However, shareholders holding such shares will receive the benefit of
the value of such shares towards reduced sales charges on purchases of Class A
shares pursuant to the Fund's "Right of Accumulation" (see "Initial Sales Charge
Alternative--Class A Shares--Right of Accumulation"). Investors who require a $5
million minimum initial investment to qualify to purchase Class D shares may
satisfy that requirement by investing that amount in a single transaction in
Class D shares of the Fund and other Dean Witter Multi-Class

 
                                       22
<PAGE>


Funds, subject to the $1,000 minimum initial investment required for that Class
of the Fund. In addition, for the purpose of meeting the $5 million minimum
investment amount, holdings of Class A shares in all Dean Witter Multi-Class
Funds, shares of FSC Funds and shares of Dean Witter Funds for which such shares
have been exchanged will be included together with the current investment
amount. If a shareholder redeems Class A shares and purchases Class D shares,
such redemption may be a taxable event.

 

PLAN OF DISTRIBUTION

 

    Effective July 28, 1997, the Fund has adopted a Plan of Distribution
pursuant to Rule 12b-1 under the Act with respect to the distribution of Class
A, Class B and Class C shares of the Fund. In the case of Class A and Class C
shares, the Plan provides that the Fund will reimburse the Distributor and
others for the expenses of certain activities and services incurred by them
specifically on behalf of those shares. Reimbursements for these expenses will
be made in monthly payments by the Fund to the Distributor, which will in no
event exceed amounts equal to payments at the annual rates of 0.25% and 0.85% of
the average daily net assets of Class A and Class C, respectively. In the case
of Class B shares, the Plan provides that the Fund will pay the Distributor a
fee, which is accrued daily and paid monthly, at the annual rate of 0.75% of the
average daily net assets of Class B. The fee is treated by the Fund as an
expense in the year it is accrued. In the case of Class A shares, the entire
amount of the fee currently represents a service fee within the meaning of the
NASD guidelines. In the case of Class B and Class C shares, a portion of the fee
payable pursuant to the Plan, equal to 0.20% and 0.25% of the average daily net
assets of each of these Classes, respectively, is currently characterized as a
service fee. A service fee is a payment made for personal service and/or the
maintenance of shareholder accounts.

 

    Additional amounts paid under the Plan in the case of Class B and Class C
shares are paid to the Distributor for services provided and the expenses borne
by the Distributor and others in the distribution of the shares of those
Classes, including the payment of commissions for sales of the shares of those
Classes and incentive compensation to and expenses of DWR's account executives
and others who engage in or support distribution of shares or who service
shareholder accounts, including overhead and telephone expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders; and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may utilize fees paid pursuant to the Plan 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, at any given time, the expenses in
distributing Class B shares of the Fund may be in excess of the total of (i) the
payments made by the Fund pursuant to the Plan, and (ii) the proceeds of CDSCs
paid by investors upon the redemption of Class B shares. For example, if $1
million in expenses in distributing Class B shares of the Fund had been incurred
and $750,000 had been received as described in (i) and (ii) above, the excess
expense would amount to $250,000. Because there is no requirement under the Plan
that the Distributor be reimbursed for all distribution expenses or any
requirement that the Plan be continued from year to year, such excess amount
does not constitute a liability of the Fund. Although there is no legal
obligation for the Fund to pay expenses incurred in excess of payments made to
the Distributor under the Plan, and the proceeds of CDSCs 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

 
                                       23

<PAGE>

CDSCs, may or may not be recovered through future distribution fees or CDSCs.

 

    In the case of Class A and Class C shares, expenses incurred pursuant to the
Plan in any calendar year in excess of 0.25% or 0.85% 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 commission credited to account executives at the time of sale may be
reimbursed in the subsequent calendar year. No interest or other financing
charges will be incurred on any Class A or Class C distribution expenses
incurred by the Distributor under the Plan or on any unreimbursed expenses due
to the Distributor pursuant to the Plan.

 
DETERMINATION OF NET ASSET VALUE
 

    The net asset value per share is determined once daily at 4:00 p.m., New
York time on each day that the New York Stock Exchange is open (or, on days when
the New York Stock Exchange closes prior to 4:00 p.m., at such earlier time), by
taking the net assets of the Fund, dividing by the number of shares outstanding
and adjusting to the nearest cent. The assets belonging to the Class A, Class B,
Class C and Class D shares will be invested together in a single portfolio. The
net asset value of each Class, however, will be determined separately by
subtracting each Class's accrued expenses and liabilities. The net asset value
per share will not be determined on Good Friday and on such other federal and
non-federal holidays as are observed by the New York Stock Exchange.

 

    In the calculation of the Fund's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange or other
domestic or foreign exchange is valued at its latest sale price on that exchange
prior to the time assets are valued; (if there were no sales that day, the
security is valued at the latest bid price); and (2) all other portfolio
securities for which over-the-counter market quotations are readily available
are valued at the latest bid price. When market quotations are not readily
available, including circumstances under which it is determined by the
Investment Manager that sale or bid prices are not reflective of a security's
market value, portfolio securities are valued at their fair value as determined
in good faith under procedures established by and under the general supervision
of the Fund's Board of Directors (valuation of securities for which market
quotations are not readily available may be based upon current market prices of
securities which are comparable in coupon, rating and maturity or an appropriate
matrix utilizing similar factors).

 
    Certain of the Fund's portfolio securities may be valued by an outside
pricing service approved by the Fund's Directors. The pricing service may
utilize a matrix system incorporating security quality, maturity and coupon as
the evaluation model parameters, and/or research evaluations by its staff,
including review of broker-dealer market price quotations, in determining what
it believes is the fair valuation of the portfolio securities valued by such
pricing service.
 
    Municipal securities will be valued for the Fund by an outside computer
matrix pricing service approved by the Board of Directors. Periodically, the
Investment Manager and the Board of Directors review the continued
appropriateness of the prices obtained through the service.
 
    Short-term debt securities with remaining maturities of 60 days or less at
the time of purchase are valued at amortized cost, unless the Board determines
such does not reflect the securities' fair value, in which case these securities
will be valued at their fair market value as determined by the Board of
Directors. Other short-term debt securities will be valued on a marked-to-market
basis until such time as they reach a maturity of 60 days, whereupon they will
be valued at amortized cost using their value on the 61st day unless the
Directors determine such does not reflect the securities' market value, in which
case these securities will be valued at their fair market value as determined by
the Board of Directors. Listed options on debt securities are val-
 
                                       24
<PAGE>

ued 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 closing 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 price. Futures are valued at the latest sale
price on the commodities exchange on which they trade unless the Directors
determine that such price does not reflect their market value, in which case
they will be valued at their fair value as determined by the Board of Directors.
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 Board of Directors.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 

    Automatic Investment of Dividends and Distributions.  All income dividends
and capital gains distributions are automatically paid in full and fractional
shares of the applicable Class of the Fund (or, if specified by the shareholder,
in shares of any other open-end Dean Witter Fund), unless the shareholder
requests that they be paid in cash. Shares so acquired are acquired at net asset
value and are not subject to the imposition of a front-end sales charge or a
CDSC (see "Redemptions and Repurchases").

 

    Investment of Distributions Received in Cash. Any shareholder who receives a
cash payment representing a dividend or capital gains distribution may invest
such dividend or distribution in shares of the applicable Class at the net asset
value next determined after receipt by the Transfer Agent, by returning the
check or the proceeds to the Transfer Agent within thirty days after the payment
date. Shares so acquired are acquired at net asset value and are not subject to
the imposition of a front-end sales charge or a CDSC (see "Redemptions and
Repurchases").

 

    Easyinvest(SM).  Shareholders may subscribe to EasyInvest, an automatic
purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account or following
redemption of shares of a Dean Witter money market fund, on a semi-monthly,
monthly or quarterly basis, to the Fund's Transfer Agent for investment in
shares of the Fund (see "Purchase of Fund Shares" and "Redemptions and
Repurchases--Involuntary Redemption").

 

    Systematic Withdrawal Plan.  A 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 plan
provides for monthly or quarterly (March, June, September, December) checks in
any 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.
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.

 

    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.

 

    Tax-Sheltered Retirement Plans.  Retirement plans are available through the
Investment Manager for use by corporations, the self-employed, Individual
Retirement Accounts and Custodial Accounts

 
                                       25

under Section 403(b)(7) of the Internal Revenue Code. Adoption of such plans
should be on advice of legal counsel or tax adviser.
 
    For further information regarding plan administration, custodial fees and
other details, investors should contact the Fund.
 

EXCHANGE PRIVILEGE

 

    Shares of each Class may be exchanged for shares of the same Class of any
other Dean Witter Multi-Class Fund without the imposition of any exchange fee.
Shares may also be exchanged for shares 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 "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. There is no holding
period for exchanges of shares acquired by exchange or dividend reinvestment.

 

    An exchange to another Dean Witter Multi-Class Fund, any FSC Fund, any CDSC
Fund or any Exchange Fund that is not a money market fund is on the basis of the
next calculated net asset value per share of each fund after the exchange order
is received. When exchanging into a money market fund from the Fund, shares of
the Fund are redeemed out of the Fund at their next calculated net asset value
and the proceeds of the redemption are used to purchase shares of the money
market fund at their net asset value determined the following business day.
Subsequent exchanges between any of the money market funds and any of the Dean
Witter Multi-Class Funds, FSC Funds or CDSC Funds or any Exchange Fund that is
not a money market fund can be effected on the same basis.

 

    No CDSC is imposed at the time of any exchange of shares, although any
applicable CDSC will be imposed upon ultimate redemption. During the period of
time the shareholder remains in an Exchange Fund (calculated from the last day
of the month in which the Exchange Fund shares were acquired), the holding
period (for the purpose of determining the rate of the CDSC) is frozen. If those
shares are subsequently re-exchanged for shares of a Dean Witter Multi-Class
Fund or shares of a CDSC Fund, the holding period previously frozen when the
first exchange was made resumes on the last day of the month in which shares of
a Dean Witter Multi-Class Fund or shares of a CDSC Fund are reacquired. Thus,
the CDSC is based upon the time (calculated as described above) the shareholder
was invested in shares of a Dean Witter Multi-Class Fund or in shares of a CDSC
Fund (see "Purchase of Fund Shares"). 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 shares of a FSC
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 incurred on or after
that date which are attributable to those shares. (Exchange Fund 12b-1
distribution fees are described in the prospectuses for those funds.) Class B
shares of the Fund acquired in exchange for Class B shares of another Dean
Witter Multi-Class Fund or shares of a CDSC Fund having a different CDSC
schedule than that of this Fund will be subject to the higher CDSC

 
                                       26
<PAGE>


schedule, even if such shares are subsequently re-exchanged for shares of the
fund with the lower CDSC schedule.

 

    Additional Information Regarding Exchanges. Purchases and exchanges should
be made for investment purposes only. A pattern of frequent exchanges may be
deemed by the Investment Manager to be abusive and contrary to the best
interests of the Fund's other shareholders and, at the Investment Manager's
discretion, may be limited by the Fund's refusal to accept additional purchases
and/ or exchanges from the investor. Although the Fund does not have any
specific definition of what constitutes a pattern of frequent exchanges, and
will consider all relevant factors in determining whether a particular situation
is abusive and contrary to the best interests of the Fund and its other
shareholders, investors should be aware that the Fund and each of the other Dean
Witter Funds may in their discretion limit or otherwise restrict the number of
times this Exchange Privilege may be exercised by any investor. Any such
restriction will be made by the Fund on a prospective basis only, upon notice to
the shareholder not later than ten days following such shareholder's most recent
exchange. Also, the Exchange Privilege may be terminated or revised at any time
by the Fund and/or any of such Dean Witter Funds for which shares of the Fund
have been exchanged, upon such notice as may be required by applicable
regulatory agencies. Shareholders maintaining margin accounts with DWR or
another Selected Broker-Dealer are referred to their account executive regarding
restrictions on exchange of shares of the Fund pledged in the margin account.

 

    The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain a copy and examine it carefully
before investing. Exchanges are subject to the minimum investment requirement of
each Class of shares and any other conditions imposed by each fund. In the case
of a shareholder holding a share certificate or certificates, no exchanges may
be made until all applicable share certificates have been received by the
Transfer Agent and deposited in the shareholder's account. An exchange will be
treated for federal income tax purposes the same as a repurchase or redemption
of shares, on which the shareholder may realize a capital gain or loss. However,
the ability to deduct capital losses on an exchange may be limited in situations
where there is an exchange of shares within ninety days after the shares are
purchased. The Exchange Privilege is only available in states where an exchange
may legally be made.

 
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account numbers are part of the account information, shareholders may
initiate an exchange of shares of the Fund for shares of any of the Dean Witter
Funds (for which the Exchange Privilege is available) pursuant to this Exchange
Privilege by contacting their DWR or other Selected Broker-Dealer account
executive (no Exchange Privilege Authorization Form is required). Other
shareholders (and those shareholders who are clients of DWR or other Selected
Broker-Dealer but who wish to make exchanges directly by telephoning the
Transfer Agent) must complete and forward to the Transfer Agent an Exchange
Privilege Authorization form, copies of which may be obtained from the Transfer
Agent, to initiate an exchange. If the Authorization Form is used, exchanges may
be made in writing or by contacting the Transfer Agent at (800) 869-NEWS
(toll-free).
 
    The Fund will employ reasonable procedures to confirm that exchange
instructions communicated over the telephone are genuine. Such procedures may
include requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number and DWR or other
Selected Broker-Dealer account number (if any). Telephone instructions may also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses due to unauthorized or fraudulent instructions.
 
                                       27
<PAGE>

    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m. and 4:00 p.m. New York time, on any day the New York
Stock Exchange is open. Any shareholder wishing to make an exchange who has
previously filed an Exchange Privilege Form and who is unable to reach the Fund
by telephone should contact his or her DWR or other Selected Broker-Dealer
account executive, if appropriate, or make a written exchange request.
Shareholders are advised that during periods of drastic economic or market
changes, it is possible that the telephone exchange procedures may be difficult
to implement, although this has not been the experience of the Dean Witter Funds
in the past.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about the
Exchange Privilege.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 

    Redemption.  Shares of each Class of the Fund can be redeemed for cash at
any time at the current net asset value per share next determined less the
amount of any applicable CDSC in the case of Class A, Class B or Class C shares
(see "Purchase of Fund Shares"). If shares are held in a shareholder's account
without a stock certificate, a written request for redemption is required. If
certificates are held by the shareholder, the shares may be redeemed by
surrendering the certificates with a written request for redemption along with
any additional information requested by the Transfer Agent.

 

    Repurchase.  DWR and other Selected Broker-Dealers are authorized to
repurchase, as agent for the Fund, shares represented by a stock certificate
which is delivered to any of their offices. Shares held in a shareholder's
account without a stock certificate may also be repurchased by DWR and other
Selected Broker-Dealers upon the telephonic request of the shareholder. The
repurchase price is the net asset value next determined (see "Purchase of Fund
Shares") after such repurchase order is received by DWR or other Selected
Broker-Dealer reduced by any applicable CDSC.

 

    The CDSC, if any, will be the only fee imposed by the Fund, the Distributor,
DWR or other Selected Broker-Dealers. The offer by DWR and other Selected
Broker-Dealers to repurchase shares may be suspended without notice by them at
any time. In that event, shareholders may redeem their shares through the Fund's
Transfer Agent as set forth above under "Redemption."

 

    Payment for Shares Redeemed or Repurchased.  Payment for shares presented
for repurchase or redemption will be made by check within seven days after
receipt by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended at
times when normal trading is not taking place on the New York Stock Exchange. If
the shares to be redeemed have recently been purchased by check, payment of the
redemption proceeds may be delayed for the minimum time needed to verify that
the check used for investment has been honored (not more than fifteen days from
the time of receipt of the check by the Transfer Agent). Shareholders
maintaining margin accounts with DWR and other Selected Broker Dealers are
referred to their account executive regarding restrictions on redemption of
shares of the Fund pledged in the margin account.

 

    Reinstatement Privilege.  A shareholder who has had his or her shares
redeemed or repurchased and has not previously exercised this reinstatement
privilege may, within 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 from which such shares were redeemed or
repurchased, at their net asset value next determined after a rein-
 
                                       28

<PAGE>

statement request, together with the proceeds, is received by the Transfer Agent
and receive a pro rata credit for any CDSC paid in connection with such
repurchase or redemption.

 

    Involuntary Redemption.  The Fund reserves the right, on sixty days' notice,
to redeem, at their net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or custodial account under
Section 403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less than $100, or such lesser amount as
may be fixed by the Board of Directors or, in the case of an account opened
through EasyInvest, if after twelve months the shareholder has invested less
than $1,000 in the account. However, before the Fund redeems such shares and
sends the proceeds to the shareholder, it will notify the shareholder that the
value of the shares is less than the applicable amount and allow the shareholder
sixty days in which to make an additional investment in an amount which will
increase the value of the account to at least the applicable amount or more
before the redemption is processed. No CDSC will be imposed on any involuntary
redemption.

 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 

    Dividends and Distributions.  The Fund declares dividends separately for
each Class of shares and intends to declare and pay monthly income dividends and
to distribute net short-term and net long-term capital gains, if any, at least
once each year. The Fund may, however, determine either to distribute or to
retain all or part of any long-term capital gains in any year for reinvestment.

 

    All dividends and capital gains distributions will be paid in additional
shares of the same Class and automatically credited to the shareholder's account
without issuance of a stock certificate unless the shareholder requests in
writing that all dividends be paid in cash. Shares acquired by dividend and
distribution reinvestments will not be subject to any front-end sales charge or
CDSC. Class B shares acquired through dividend and distribution reinvestments
will become eligible for conversion to Class A shares on a pro rata basis.
Distributions paid on Class A and Class D shares will be higher than for Class B
and Class C shares because distribution fees paid by Class B and Class C shares
are higher. (See "Shareholder Services--Automatic Investment of Dividends and
Distributions.")

 
    Taxes.  Because the Fund intends to distribute all of its net investment
income and net capital gains to shareholders and otherwise continue to qualify
as a regulated investment company under Subchapter M of the Internal Revenue
Code, it is not expected that the Fund will be required to pay any Federal
income tax on such income and capital gains.
 
    With respect to the Fund's investments in zero coupon and payment-in-kind
bonds, the Fund accrues income prior to any actual cash payments by their
issuers. In order to continue to comply with Subchapter M of the Internal
Revenue Code and remain able to forego payment of Federal income tax on its
income and capital gains, the Fund must distribute all of its net investment
income, including income accrued from zero coupon and payment-in-kind bonds. As
such, the Fund may be required to dispose of some of its portfolio securities
under disadvantageous circumstances to generate the cash required for
distribution.
 
    Shareholders will normally have to pay Federal income taxes, and any
applicable state and/or local income taxes, on the dividends and distributions
they receive from the Fund. Such dividends and distributions, to the extent they
are derived from net investment income or net short-term capital gains, are
taxable to the shareholder as ordinary dividend income regardless of whether the
shareholder receives such distributions in additional shares or in cash. Any
dividends declared in the last calendar quarter of any year to shareholders of
record for that
 
                                       29
<PAGE>

period which are paid in the following year prior to February 1 will be deemed
received by the shareholder in the prior year. Since the Fund's income is
expected to be derived primarily from interest rather than dividends, only a
small portion, if any, of such dividends and distributions is expected to be
eligible for the Federal dividends received deduction available to corporations.
 
    Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash. Capital gains distributions are not eligible for
the dividends received deduction. Capital gains may be generated by transactions
in options and futures contracts engaged in by the Fund.
 
    The Fund may at times make payments from sources other than income or net
capital gains. Payments from such sources will, in effect, represent a return of
a portion of each shareholder's investment. All, or a portion, of such payments
will not be taxable to shareholders.
 
    After the end of the calendar year, shareholders will receive a statement of
their dividends and capital gains distributions for tax purposes, including
information as to the portion taxable as ordinary income and the portion taxable
as capital gains.
 
    To avoid being subject to a 31% Federal backup withholding tax on taxable
dividends, capital gains distributions and the proceeds of redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
 
    Shareholders should consult their tax advisers regarding specific questions
as to state or local taxes and as to the applicability of the foregoing to their
current federal tax situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 

    From time to time the Fund may quote its "yield" and/or its "total return"
in advertisements and sales literature. These figures are computed separately
for Class A, Class B, Class C and Class D shares. Both the yield and the total
return of the Fund are based on historical earnings and are not intended to
indicate future performance. The yield of each Class of the Fund will be
computed by dividing the Class's net investment income over a 30-day period by
an average value (using the average number of shares entitled to receive
dividends and the maximum offering price per share at the end of the period),
all in accordance with applicable regulatory requirements. Such amount will be
compounded for six months and then annualized for a twelve-month period to
derive the Fund's yield for each Class.

 

    The "average annual total return" of the Fund refers to a figure reflecting
the average annualized percentage increase (or decrease) in the value of an
initial investment in a Class of the Fund of $1,000 over periods of one, five
and ten years. Average annual total return reflects all income earned by the
Fund, any appreciation or depreciation of the Fund's assets, all expenses
incurred by the applicable Class and all sales charges incurred by shareholders,
for the stated periods. It also assumes reinvestment of all dividends and
distributions paid by the Fund.

 

    In addition to the foregoing, the Fund may advertise its total return 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 deduction of any sales charge which, if reflected, would
reduce the performance quoted. The Fund may advertise the growth of hypothetical
investments of $10,000, $50,000 or $100,000 in each Class of shares of the Fund.
The Fund from time to time may also advertise its performance relative to 
certain performance rankings and indexes compiled by independent organizations,
such as mutual fund performance rankings of Lipper Analytical Services, Inc.


                                       30
<PAGE>


    Prior to July 28, 1997 the Fund offered only one Class of shares. Because
the distribution arrangement for Class A most closely resembles the distribution
arrangement applicable prior to the implementation of multiple classes,
historical performance information may be restated to reflect the current
maximum sales charge applicable to Class A. In addition, because all shares of
the Fund held prior to July 28, 1997 have been designated Class D shares, the
Fund's historical performance may also be restated to reflect the absence of any
sales charge in the case of Class D shares.

 
ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 

    Voting Rights.  All shares of the Fund are of common stock of $0.01 par
value and are equal as to earnings, assets and voting privileges except that
each Class will have exclusive voting privileges with respect to matters
relating to distribution expenses borne solely by such Class or any other matter
in which the interests of one Class differ from the interests of any other
Class. In addition, Class B shareholders will have the right to vote on any
proposed material increase in Class A's expenses, if such proposal is submitted
separately to Class A shareholders. Also, as discussed herein, Class A, Class B
and Class C bear the expenses related to the distribution of their respective
shares.

 
    Under ordinary circumstances, the Fund is not required, nor does it intend,
to hold Annual Meetings of Stockholders. The Directors may call Special Meetings
of Stockholders for action by stockholder vote as may be required by the Act or
the Fund's By-Laws.
 
    Code of Ethics.  Directors, officers and employees of InterCapital, Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest, that no undue personal benefit is obtained from a person's employment
activities and that actual and potential conflicts of interest are avoided. To
achieve these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an advance clearance process to monitor that no
Dean Witter Fund is engaged at the same time in a purchase or sale of the same
security. The Code of Ethics bans the purchase of securities in an initial
public offering, and also prohibits engaging in futures and options transactions
and profiting on short-term trading (that is, a purchase within 60 days of a
sale or a sale within 60 days of a purchase) of a security. In addition,
investment personnel may not purchase or sell a security for their personal
account within 30 days before or after any transaction in any Dean Witter Fund
managed by them. Any violations of the Code of Ethics are subject to sanctions,
including reprimand, demotion or suspension or termination of employment. The
Code of Ethics comports with regulatory requirements and the recommendations in
the 1994 report by the Investment Company Institute Advisory Group on Personal
Investing.
 

    Master/feeder Conversion.  The Fund reserves the right to seek to achieve
its investment objectives by investing all of its investable assets in a
diversified, open-end management investment company having the same investment
objectives and policies and substantially the same investment restrictions as
those applicable to the Fund.

 
    Shareholder Inquiries.  All inquiries regarding the Fund should be directed
to the Fund at the telephone numbers or address set forth on the front cover of
this Prospectus.

APPENDIX -- RATINGS OF INVESTMENTS
- --------------------------------------------------------------------------------
 
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")

                                  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.
 
Ba         Bonds which are rated Ba are judged to have speculative elements;
           their future cannot be considered as well assured. Often the
           protection of interest and principal payments may be very moderate,
           and therefore not well safeguarded during both good and bad times
           over the future. Uncertainty of position characterizes bonds in this
           class.

B          Bonds which are rated B generally lack characteristics of desirable
           investments. Assurance of interest and principal payments or of
           maintenance of other terms of the contract over any long period of
           time may be small.

Caa        Bonds which are rated Caa are of poor standing. Such issues may be in
           default or there may be present elements of danger with respect to
           principal or interest.

Ca         Bonds which are rated Ca present obligations which are speculative in
           a high degree. Such issues are often in default or have other marked
           shortcomings.

C          Bonds which are rated C are the lowest rated class of bonds, and
           issues so rated can be regarded as having extremely poor prospects of
           ever attaining any real investment standing.

 
                                       32
<PAGE>

        Conditional Rating:  Municipal bonds for which the security depends
    upon the completion of some act or the fulfillment of some condition are
    rated conditionally. These are bonds secured by (a) earnings of projects
    under construction, (b) earnings of projects unseasoned in operation
    experience, (c) rentals which begin when facilities are completed, or
    (d) payments to which some other limiting condition attaches.
    Parenthetical rating denotes probable credit stature upon completion of
    construction or elimination of basis of condition.
 
        Rating Refinements:  Moody's may apply numerical modifiers, 1, 2 and
    3 in each generic rating classification from Aa through B in its
    corporate and municipal bond rating system. The modifier 1 indicates
    that the security ranks in the higher end of its generic rating
    category; the modifier 2 indicates a mid-range ranking; and a modifier 3
    indicates that the issue ranks in the lower end of its generic rating
    category.
 
                            COMMERCIAL PAPER RATINGS
 
        Moody's Commercial Paper ratings are opinions of the ability to
    repay punctually promissory obligations not having an original maturity
    in excess of nine months. Moody's employs the following three
    designations, all judged to be investment grade, to indicate the
    relative repayment capacity of rated issuers: Prime-1, Prime-2, Prime-3.
 
        Issuers rated Prime-1 have a superior capacity for repayment of
    short-term promissory obligations. Issuers rated Prime-2 have a strong
    capacity for repayment of short-term promissory obligations; and Issuers
    rated Prime-3 have an acceptable capacity for repayment of short-term
    promissory obligations. Issuers rated Not Prime do not fall within any
    of the Prime rating categories.
 
    STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                                  BOND RATINGS
 
        A Standard & Poor's bond rating is a current assessment of the
    creditworthiness of an obligor with respect to a specific obligation.
    This assessment may take into consideration obligors such as guarantors,
    insurers, or lessees.
 
        The ratings are based on current information furnished by the issuer
    or obtained by Standard & Poor's from other sources it considers
    reliable. The ratings are based, in varying degrees, on the following
    considerations: (1) likelihood of default-capacity and willingness of
    the obligor as to the timely payment of interest and repayment of
    principal in accordance with the terms of the obligation; (2) nature of
    and provisions of the obligation; and (3) protection afforded by, and
    relative position of, the obligation in the event of bankruptcy,
    reorganization or other arrangement under the laws of bankruptcy and
    other laws affecting creditors' rights.
 
        Standard & Poor's does not perform an audit in connection with any
    rating and may, on occasion, rely on unaudited financial information.
    The ratings may be changed, suspended or withdrawn as a result of
    changes in, or unavailability of, such information, or for other
    reasons.
 

        
    AAA    Debt rated AAA has the highest rating assigned by Standard & Poor's.
           Capacity to pay interest and repay principal is extremely strong.

    AA     Debt rated AA has a very strong capacity to pay interest and repay
           principal and differs from the highest-rated issues only in small
           degree.

A          Debt rated A has a strong capacity to pay interest and repay
           principal although they are somewhat more susceptible to the adverse
           effects of changes in circumstances and economic conditions than debt
           in higher-rated categories.

BBB        Debt rated BBB is regarded as having an adequate capacity to pay
           interest and repay principal. Whereas it normally exhibits adequate
           protection parameters, adverse economic conditions or changing
           circumstances are more likely to lead to a weakened capacity to pay
           interest and repay principal for debt in this category than for debt
           in higher-rated categories. 

           Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
 
BB         Debt rated BB has less near-term vulnerability to default than other
           speculative grade debt. However, it faces major ongoing uncertainties
           or exposure to adverse business, financial or economic conditions
           which could lead to inadequate capacity to meet timely interest and
           principal payment.

B          Debt rated B has a greater vulnerability to default but presently has
           the capacity to meet interest payments and principal repayments.
           Adverse business, financial or economic conditions would likely
           impair capacity or willingness to pay interest and repay principal.

CCC        Debt rated CCC has a current identifiable vulnerability to default,
           and is dependent upon favorable business, financial and economic
           conditions to meet timely payments of interest and repayments of
           principal. In the event of adverse business, financial or economic
           conditions, it is not likely to have the capacity to pay interest and
           repay principal.

CC         The rating CC is typically applied to debt subordinated to senior
           debt which is assigned an actual or implied CCC rating.

C          The rating C is typically applied to debt subordinated to senior debt
           which is assigned an actual or implied CCC- debt rating.

CI         The rating CI is reserved for income bonds on which no interest is
           being paid.

NR         Indicates that no rating has been requested, that there is
           insufficient information on which to base a rating or that Standard &
           Poor's does not rate a particular type of obligation as a matter of
           policy.
 
           Bonds rated BB, B, CCC, CC and C are regarded as having predominantly
           speculative characteristics with respect to capacity to pay interest
           and repay principal. BB indicates the least degree of speculation and
           C the highest degree of speculation. While such debt will likely have
           some quality and protective characteristics, these are outweighed by
           large uncertainties or major risk exposures to adverse conditions.
 
           Plus (+) or minus (-): The ratings from AA to CCC may be modified by
           the addition of a plus or minus sign to show relative standing within
           the major ratings categories.
 
           In the case of municipal bonds, the foregoing ratings are sometimes
           followed by a "p" which indicates that the rating is provisional. A
           provisional rating assumes the successful completion of the project
           being financed by the bonds being rated and indicates that payment of
           debt service requirements is largely or entirely dependent upon the
           successful and timely completion of the project. This rating,
           however, while addressing credit quality subsequent to completion of
           the project, makes no comment on the likelihood or risk of default
           upon failure of such completion.

                            COMMERCIAL PAPER RATINGS
 
        Standard and Poor's commercial paper rating is a current assessment
    of the likelihood of timely payment of debt having an original maturity
    of no more than 365 days. The commercial paper rating is not a
    recommendation to purchase or sell a security. The ratings are based
    upon current information furnished by the issuer or obtained by S&P from
    other sources it considers reliable. The ratings may be changed,
    suspended, or withdrawn as a result of changes in or unavailability of
    such information. Ratings are graded into group categories, ranging from
    "A" for the highest quality obligations to "D" for the lowest. Ratings
    are applicable to both taxable and tax-exempt commercial paper. The
    categories are as follows:
 
        Issues assigned A ratings are regarded as having the greatest
    capacity for timely payment. Issues in this category are further refined
    with the designation 1, 2 and 3 to indicate the relative degree of
    safety.
 

        
    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.

                                                     PROSPECTUS -- JULY 28, 1997

DEAN WITTER HIGH YIELD SECURITIES INC.
TWO WORLD TRADE CENTER, NEW YORK, NEW YORK 10048
LETTER TO THE SHAREHOLDERS AUGUST 31, 1996
 
DEAR SHAREHOLDER:

The fixed-income markets rebounded sharply during the second half of 1995, as
economic growth slowed and inflation fears subsided. This trend reversed itself
in the first half of 1996, as signs of an economic recovery caused the U.S.
Treasury market to retreat. The high-yield market, which performed nicely during
1995's market rally, held up relatively well during the first eight months of
1996, even as interest rates moved up sharply. While signs of an economic
recovery have led to a sharp increase in interest rates, this recovery also
bodes well for the future prospects of many corporate issuers in the high-yield
marketplace and helps erase some of the recession fears that plagued the
high-yield market in late 1995.

Against this backdrop, Dean Witter High Yield Securities Inc. produced a total
return of 11.07 percent for the twelve-month period ended August 31, 1996. Over
the past twelve months, the Fund continued to distribute regular income
dividends at a rate of $0.055 per share per month. For the full fiscal year, the
Fund's distributions totaled $0.767 per share, including an extra income
dividend of $0.107 per share paid on December 29, 1995. On August 31, 1996, the
Fund's net assets exceeded $460 million. The accompanying chart illustrates the
growth of a $10,000 investment in the Fund for the ten-year period ended August
31, 1996 versus the performance of the Lehman Brothers Mutual Fund
Corporate/High Yield Index. (The Fund commenced operations on September 26,
1979.)

INVESTMENT STRATEGY

The Fund's investment strategy remained essentially unchanged over the past
year, with a continued emphasis on discontinued B-rated issues. In today's
market, many of these issues can be purchased below par providing significant
future appreciation potential and an attractive yield versus comparable
Treasuries (in the 11 percent to 12 percent range). In light of the rebounding
economy, we feel quite comfortable
<PAGE>
DEAN WITTER HIGH YIELD SECURITIES INC.
LETTER TO THE SHAREHOLDERS AUGUST 31, 1996, CONTINUED
 
with the earnings outlook for most of our B-rated issuers. Recognizing that the
economy may slow somewhat during the remainder of 1996, we have tried to limit
the portfolio's volatility by 
focusing primarily on growth type,              [GRAPHIC]
recession resistant industry sectors
such as cable, media, foods and
beverages and telecommunications.

MARKET OUTLOOK

Given our outlook for continued, albeit
moderate economic growth, we find that
many of today's B-rated issues offer
excellent long-term return potential.
Over the near term, there could be
continued volatility in the financial
markets as investors assess the
economy's strength, possible Federal
Reserve Board actions and the upcoming
Presidential election. However, despite
any potential short-term weakness, we
consider today's high-yield market to
be an attractive long-term opportunity
for investors.

We appreciate your support of Dean
Witter High Yield Securities Inc. and
look forward to continuing to serve
your investment needs and objectives.

Very truly yours,

/s/ Charles A. Fiumefreddo

NOTES TO FINANCIAL STATEMENTS AUGUST 31, 1996
 
1. ORGANIZATION AND ACCOUNTING POLICIES

Dean Witter High Yield Securities Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's primary investment objective is to
earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund was
incorporated in Maryland on June 14, 1979.

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 or American 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; (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, portfolio securities are
valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Directors (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 portfolio securities may be valued by an outside pricing service
approved by the Directors. The pricing service utilizes a matrix system
incorporating security quality, maturity and coupon as the evaluation model
parameters, and/or research and evaluations by its staff, including review of
broker-dealer market price quotations, if available, in determining what it
believes is the fair valuation of the portfolio securities valued by such
pricing service; and (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
<PAGE>
DEAN WITTER HIGH YIELD SECURITIES INC.
NOTES TO FINANCIAL STATEMENTS AUGUST 31, 1996, CONTINUED
 
by the identified cost method. Dividend income and other distributions are
recorded on the ex-dividend date. Discounts are accreted over the life of the
respective securities. Interest income is accrued daily except where collection
is not expected.

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 with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a
management fee, calculated daily and payable monthly, by applying the following
annual rates to the net assets of the Fund determined as of the close of each
business day: 0.50% to the portion of daily net assets not exceeding $500
million; 0.425% to the portion of daily net assets exceeding $500 million but
not exceeding $750 million; 0.375% to the portion of daily net assets exceeding
$750 million but not exceeding $1 billion; 0.35% to the portion of daily net
assets exceeding $1 billion but not exceeding $2 billion; 0.325% to the portion
of daily net assets exceeding $2 billion but not exceeding $3 billion; and 0.30%
to the portion of daily net assets exceeding $3 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
<PAGE>

NOTES TO FINANCIAL STATEMENTS AUGUST 31, 1996, CONTINUED
 
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. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended August 31, 1996, aggregated
$393,514,207 and $415,856,430, respectively.

Dean Witter Trust Company, an affiliate of the Investment Manager, is the Fund's
transfer agent. At August 31, 1996, the Fund had transfer agent fees and
expenses payable of approximately $57,000.

The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Directors of the Fund who will have served as independent
Directors/Trustees for at least five years at the time of retirement. Benefits
under this plan are based on years of service and compensation during the last
five years of service. Aggregate pension costs for the year ended August 31,
1996 included in Directors' fees and expenses in the Statement of Operations
amounted to $1,274. At August 31, 1996, the Fund had an accrued pension
liability of $49,856 which is included in accrued expenses in the Statement of
Assets and Liabilities.

Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Distributor has
informed the Fund that for the year ended August 31, 1996, it received
approximately $1,595,000 in commissions from the sale of shares of the Fund's
capital stock. Such commissions are deducted from the proceeds of the capital
stock shares and are not an expense of the Fund.

attributable to post-October losses, capital loss deferrals on wash sales and
dividend payable and permanent book/tax differences primarily attributable to an
expired capital loss carryover. To reflect reclassifications arising from
permanent book/tax differences for the year ended August 31, 1996,
paid-in-capital was charged and accumulated net realized loss was credited
$37,795,049.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
OF DEAN WITTER HIGH YIELD SECURITIES INC.

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 High Yield Securities
Inc. (the "Fund") at August 31, 1996, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the ten years in the
period then ended, 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 August
31, 1996 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

DEAN WITTER HIGH YIELD SECURITIES INC.      Two World Trade Center, New York, 
LETTER TO THE SHAREHOLDERS                  New York 10048 
February 28, 1997 

DEAR SHAREHOLDER: 

Continuing its strong performance of the first half of 1996, the high-yield 
market posted solid returns during the past six months and outperformed most 
of the other fixed-income markets. With the economy rebounding and with 
corporate earnings holding up well, the market was able to offset what was a 
relatively weak fixed-income environment. 

A year ago, investors were anticipating a recession due to concern over a 
then-weakening economy. U.S. Treasury yields were lower than today's levels, 
while yields in the high-yield market were higher. As the year played out, we 
saw the economy bounce back, corporate earnings hold up, the equity markets 
reach all time highs and recession fears ease. The result was a somewhat 
volatile U.S. Treasury market, while the high-yield market held up well given 
the stronger-than-expected economy. Although yield spreads narrowed during 
the year, many B-rated issues still provide an attractive yield advantage 
over U.S. Treasuries (nearly 400 basis points) and trade at or below par. 

As Dean Witter High Yield Securities begins the second half of its fiscal 
year, we note that a correction is underway across most of the financial 
markets, including the high-yield bond sector. On the heels of a credit 
tightening by the Federal Reserve Board in late March, considerable 
nervousness was evident in both the equity and fixed-income markets. 
Speculation as to the timing and impact of any further increases in interest 
rates has created uncertainty on the part of many investors. The high-yield 
market has felt this weakness as well, as investors discount a future 
potential slowing in the economy resulting from today's higher interest 
rates. 

PERFORMANCE AND PORTFOLIO STRATEGY 

Against this backdrop, Dean Witter High Yield Securities produced a total 
return of 6.92 percent for the six-month period ended February 28, 1997, 
based on its net asset value (NAV) of $6.66 per share. This compares to a 
return of 8.74 percent for the Lehman High Yield Index and a return of 

<PAGE>

DEAN WITTER HIGH YIELD SECURITIES INC. 
LETTER TO THE SHAREHOLDERS, continued 

8.76 percent for the Lipper High Yield Fund Index during the same period. 
Over the past six months, the Fund continued to distribute regular income 
dividends at a rate of $0.055 per share per month. For the full six-month 
period, the Fund's distributions totaled $0.50 per share, including an extra 
income dividend of $0.17 per share paid on December 31, 1996. On February 28, 
1997, the Fund's net assets exceeded $472 million. 

As the economy continued to expand over the past few years, we have tended to 
concentrate on B-rated issues. In a growing economy, one can find 
undervalued, "upgrade" candidates in this sector of the market that provide 
attractive yields as well as appreciation potential. As such, we continue to 
feel that many of these issues are very attractive long-term investments. 
However, given a potentially slowing economy down the road, we have begun to 
take some defensive steps in the portfolio. Over the past six to nine months, 
we have upgraded the portfolio by increasing our allocation to the 
higher-quality end of the market (BB-rated issues or higher) from 10 percent 
to 25 percent. We also sold many of our heavy cyclical positions and are now 
focused mainly on the more predictable recession-resistant or growth sectors 
of the economy. In certain of these sectors, such as media and 
telecommunications, we expect to see continued consolidation, which should 
bode well for most industry participants. 

LOOKING AHEAD 

Overall, we continue our focus on discounted B-rated investments yielding 10 
percent or higher. However, while we are not expecting a recession in 1997, 
we have begun to take a more defensive approach in case of any further 
economic slowing down the road. 

We thank you for your continued support of Dean Witter High Yield Securities 
and look forward to continuing to serve your investment needs. 

Very truly yours, 

/s/ Charles A. Fiumefreddo

DEAN WITTER HIGH YIELD SECURITIES INC. 
NOTES TO FINANCIAL STATEMENTS February 28, 1997 (unaudited) 

1. Organization and Accounting Policies 

Dean Witter High Yield Securities Inc. (the "Fund") is registered under the 
Investment Company Act of 1940, as amended, as a diversified, open-end 
management investment company. The Fund's primary investment objective is to 
earn a high level of current income and, as a secondary objective, capital 
appreciation, but only when consistent with its primary objective. The Fund 
was incorporated in Maryland on June 14, 1979 and commenced operations on 
September 26, 1979. 

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 Directors); (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 Directors (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 portfolio 
securities may be valued by an outside pricing service approved by the 
Directors. 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.

DEAN WITTER HIGH YIELD SECURITIES INC. 
NOTES TO FINANCIAL STATEMENTS February 28, 1997 (unaudited) continued 

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. Dividend income and other distributions are recorded on the 
ex-dividend date. Discounts are accreted over the life of the respective 
securities. Interest income is accrued daily except where collection is not 
expected. 

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, calculated daily and payable monthly, by applying 
the following annual rates to the net assets of the Fund determined as of the 
close of each business day: 0.50% to the portion of daily net assets not 
exceeding $500 million; 0.425% to the portion of daily net assets exceeding 
$500 million but not exceeding $750 million; 0.375% to the portion of daily 
net assets exceeding $750 million but not exceeding $1 billion; 0.35% to the 
portion of daily net assets exceeding $1 billion but not exceeding $2 
billion; 0.325% to the portion of daily net assets exceeding $2 billion but 
not exceeding $3 billion; and 0.30% to the portion of daily net assets
exceeding $3 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. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES 

The cost of purchases and proceeds from sales of portfolio securities, 
excluding short-term investments, for the six months ended February 28, 1997, 
aggregated $237,747,854 and $220,427,940, respectively. 

Dean Witter Trust Company, an affiliate of the Investment Manager, is the 
Fund's transfer agent. At February 28, 1997, the Fund had transfer agent fees 
and expenses payable of approximately $56,000. 

The Fund has an unfunded noncontributory defined benefit pension plan 
covering all independent Directors of the Fund who will have served as 
independent Directors for at least five years at the time of retirement. 
Benefits under this plan are based on years of service and compensation 
during the last five years of service. Aggregate pension costs for the six 
months ended February 28, 1997 included in Directors' fees and expenses in 
the Statement of Operations amounted to $635. At February 28, 1997, the Fund 
had an accrued pension liability of $48,911 which is included in accrued 
expenses in the Statement of Assets and Liabilities. 

Shares of the Fund are distributed by Dean Witter Distributors Inc. (the 
"Distributor"), an affiliate of the Investment Manager. The Distributor has 
informed the Fund that for the six months ended February 28, 1997, it 
received approximately $963,000 in commissions from the sale of shares of the 
Fund's capital stock. Such commissions are deducted from the proceeds of the 
capital stock shares and are not an expense of the Fund. 

4. CAPITAL STOCK

              JUNE 16, 1997

 
              Dean Witter High Income Securities (the "Fund") is an open-end
diversified management investment company whose primary investment objective is
to earn a high level of current income. As a secondary objective, the Fund will
seek capital appreciation, but only when consistent with its primary objective.
The Fund seeks high current income by investing principally in fixed-income
securities which are rated in the lower categories by established rating
services (Ba or lower by Moody's Investors Service, Inc. or BB or lower by
Standard & Poor's Corporation) or are non-rated securities of comparable
quality.
 
               THE FUND INVESTS PREDOMINANTLY IN LOWER-RATED FIXED-INCOME
SECURITIES COMMONLY KNOWN AS JUNK BONDS AND INVESTORS SHOULD CAREFULLY CONSIDER
THE RISKS THEY PRESENT, INCLUDING THE RISK OF DEFAULT. BONDS OF THIS TYPE ARE
SUBJECT TO GREATER RISKS THAN HIGHER-RATED SECURITIES AND ARE CONSIDERED TO BE
SPECULATIVE WITH REGARD TO THE PAYMENT OF INTEREST AND RETURN OF PRINCIPAL.
INVESTORS SHOULD ALSO BE COGNIZANT OF THE FACT THAT SUCH SECURITIES ARE NOT
GENERALLY MEANT FOR SHORT-TERM INVESTING AND SHOULD ASSESS THE RISKS ASSOCIATED
WITH AN INVESTMENT IN THE FUND. (SEE "RISK CONSIDERATIONS.")
 
               Shares of the Fund are continuously offered at net asset value.
However, redemptions and/or repurchases are subject in most cases to a
contingent deferred sales charge, scaled down from 4% to 1% of the amount
redeemed, if made within five years of purchase, which charge will be paid to
the Fund's Distributor, Dean Witter Distributors Inc. (See "Redemptions and
Repurchases--Contingent Deferred Sales Charge.") In addition, the Fund pays the
Distributor a distribution fee pursuant to a Rule 12b-1 Plan of Distribution at
the annual rate of 0.80% of the lesser of the (i) average daily aggregate net
sales or (ii) average daily net assets of the Fund. (See "Purchase of Fund
Shares--Plan of Distribution.")

PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 

<TABLE>
<S>               <C>
The               The Fund is organized as a Trust, commonly known as a Massachusetts business trust, and is an
Fund              open-end diversified management investment company investing principally in lower-rated fixed- income
                  securities (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Shares Offered    Shares of beneficial interest with $0.01 par value (see page 23).
- ----------------------------------------------------------------------------------------------------------------------
Offering          At net asset value without sales charge (see page 14). Shares redeemed within five years of purchase
Price             are subject to a contingent deferred sales charge under most circumstances (see page 20).
- ----------------------------------------------------------------------------------------------------------------------
Minimum Purchase  Minimum initial investment, $1,000 ($100 if the account is opened through EasyInvest-SM-); minimum
                  subsequent investment, $100 (see page 14).
- ----------------------------------------------------------------------------------------------------------------------
Investment        A high level of current income primarily; capital appreciation is secondary (see page 5).
Objective
- ----------------------------------------------------------------------------------------------------------------------
Investment        Dean Witter InterCapital Inc., the Investment Manager of the Fund, and its wholly-owned subsidiary,
Manager           Dean Witter Services Company Inc., serve in various investment management, advisory, management and
                  administrative capacities to 100 investment companies and other portfolios with assets of
                  approximately $95.6 billion at May 31, 1997 (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Management Fee    The Investment Manager receives a monthly fee at the annual rate of 0.50% of average daily net
                  assets. The fee should not be compared with fees paid by other investment companies without also
                  considering applicable sales loads and distribution fees, including those noted below (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Dividends and     Income dividends are declared and paid monthly; capital gains, if any, may be distributed at least
Capital Gains     annually. Dividends and distributions are automatically reinvested in additional shares at net asset
Distributions     value (without sales charge), unless the shareholder elects to receive cash (see page 22).
- ----------------------------------------------------------------------------------------------------------------------
Distributor and   Dean Witter Distributors Inc. (the "Distributor"). The Distributor receives from the Fund, pursuant
Distribution Fee  to a Rule 12b-1 Plan of Distribution, a distribution fee accrued daily and payable monthly at the
                  rate of 0.80% per annum of the lesser of (i) the Fund's average daily aggregate net sales or (ii)
                  the Fund's average daily net assets. This fee compensates the Distributor for the services provided
                  in distributing shares of the Fund and for its sales-related expenses. The Distributor also receives
                  the proceeds of any contingent deferred sales charges (see pages 15 and 20).
- ----------------------------------------------------------------------------------------------------------------------
Redemption--      Shares are redeemable by the shareholder at net asset value. An account may be involuntarily
Contingent        redeemed if total value of the account is less than $100 or, if the account was opened through
Deferred Sales    EasyInvest-SM-, if after twelve months the shareholder has invested less than $1,000 in the account.
Charge            Although no commission or sales charge is imposed upon the purchase of shares, a contingent deferred
                  sales charge (scaled down from 4% to 1%) is imposed on any redemption of shares if after such
                  redemption the aggregate current value of an account with the Fund falls below the aggregate amount
                  of the investor's purchase payments made during the five years preceding the redemption. However,
                  there is no charge imposed on redemption of shares purchased through reinvestment of dividends or
                  distributions (see pages 20-21).
- ----------------------------------------------------------------------------------------------------------------------
Risks             Compared with higher rated, lower yielding fixed-income securities, portfolio securities of the Fund
                  may be subject to greater risk of loss of income and principal and greater risk of increases and
                  decreases in net asset value due to market fluctuations. The Fund may also purchase when-issued and
                  delayed delivery, when, as and if issued securities, restricted securities, and zero coupon
                  securities, rights and warrants, convertible securities, foreign securities, common stock and
                  adjustable rate mortgages and enter into repurchase agreements, reverse repurchase agreements and
                  dollar rolls, options and futures transactions and forward foreign currency exchange contracts, all
                  of which involve certain special risks. Investors should review the investment objectives and
                  policies of the Fund carefully and consider their ability to assume the risks involved in purchasing
                  shares of the Fund (see pages 6-13).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean  Witter High Income Securities (the  "Fund") is an open-end diversified
management investment company. The Fund is a trust of the type commonly known as
a "Massachusetts  business  trust" and  was  organized  under the  laws  of  The
Commonwealth of Massachusetts on March 23, 1994.
 

    Dean  Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager.  The Investment  Manager, which  was incorporated  in  July,
1992,  is a wholly-owned  subsidiary of Morgan Stanley,  Dean Witter, Discover &
Co. ("MSDWD"),  a  preeminent  global financial  services  firm  that  maintains
leading  market positions in  each of its  three primary businesses--securities,
asset management and credit services.

 

    InterCapital and its wholly-owned  subsidiary, Dean Witter Services  Company
Inc.,   serve  in  various  investment   management,  advisory,  management  and
administrative capacities to 100 investment companies (the "Dean Witter Funds"),
thirty of which are listed on the New York Stock Exchange, with combined  assets
of  approximately $92.3  billion at  May 31,  1997. The  Investment Manager also
manages portfolios of  pension plans, other  institutions and individuals  which
aggregated approximately $3.3 billion at such date.

 
    The  Fund  has retained  the  Investment Manager  to  provide administrative
services, manage its business  affairs and manage the  investment of the  Fund's
assets,  including the placing of orders for  the purchase and sale of portfolio
securities. InterCapital  has  retained Dean  Witter  Services Company  Inc.  to
perform  the  aforementioned administrative  services for  the Fund.  The Fund's
Board of  Trustees  reviews  the  various services  provided  by  or  under  the
direction of the Investment Manager to ensure that the Fund's general investment
policies  and programs  are being properly  carried out  and that administrative
services are being provided to the Fund in a satisfactory manner.
 

    As full compensation for the services  and facilities furnished to the  Fund
and  for expenses of the  Fund assumed by the  Investment Manager, the Fund pays
the Investment Manager  monthly compensation  calculated daily  by applying  the
annual rate of 0.50% to the Fund's net assets determined as of the close of each
business  day. For the fiscal year ended  March 31, 1997, the Fund accrued total
compensation to the Investment Manager amounting  to an annual rate of 0.47%  of
the Fund's average daily net assets and the Fund's total expenses amounted to an
annual rate of 1.39% of the Fund's average daily net assets.

 
INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
 
    The  primary investment  objective of the  Fund is  to earn a  high level of
current  income.  As  a  secondary   objective,  the  Fund  will  seek   capital
appreciation,  but  only when  consistent  with its  primary  objective. Capital
appreciation may result, for example, from an improvement in the credit standing
of an issuer whose securities are held in the Fund's portfolio or from a general
decline in  interest  rates,  or  a combination  of  both.  Conversely,  capital
depreciation  may  result, for  example,  from a  lowered  credit standing  or a
general rise in interest rates, or a combination of both. There is no  assurance
that the objectives will be achieved. The objectives are fundamental policies of
the Fund and may not be changed without the approval of the Fund's shareholders.
The   following  policies  may  be  changed  by  the  Fund's  Trustees,  without
shareholder approval.
 
    The  higher  yields  sought  by  the  Fund  are  generally  obtainable  from
securities rated in the lower categories by recognized rating services. The Fund
seeks high current income by investing principally
 
                                       5
<PAGE>
(at  least 65% of its total assets) in fixed-income securities rated Ba or lower
by Moody's Investors  Service, Inc. ("Moody's"),  or BB or  lower by Standard  &
Poor's Corporation ("Standard & Poor's"). Fixed-income securities rated Ba or BB
or  lower by Moody's and  Standard & Poor's, respectively,  are considered to be
speculative investments. Furthermore, the Fund does not have any minimum quality
rating standard for its investments. As such, the Fund may invest in  securities
rated  as low as Caa,  Ca or C by Moody's  or CCC, CC, C, CI  or D by Standard &
Poor's. Fixed-income securities  rated Caa or  Ca by Moody's  may already be  in
default  on payment of  interest or principal,  while bonds rated  C by Moody's,
their lowest bond rating, can be regarded as having extremely poor prospects  of
ever  attaining any real  investment standing (the  Fund may purchase securities
which are  in  default and  which,  thereby,  are not  paying  its  fixed-income
security holders principal and/or interest). Bonds rated D by Standard & Poor's,
their  lowest bond rating, are  in payment default. For  a further discussion of
the characteristics and risks associated  with high yield securities, see  "Risk
Considerations"  below. A description of corporate  bond ratings is contained in
the Appendix.
 
    Non-rated securities will also be considered for investment by the Fund when
the Investment Manager believes that the  financial condition of the issuers  of
such  securities,  or the  protection afforded  by the  terms of  the securities
themselves, makes  them  appropriate  investments for  the  Fund.  Under  normal
circumstances, the dollar-weighted average maturity of the Fund's portfolio will
be between five and ten years.
 
    Up  to  35% of  the Fund's  total  assets may,  under normal  conditions, be
invested in  common  stocks;  fixed-income securities  convertible  into  common
stocks;  warrants  to  purchase  common  stocks;  investment  grade fixed-income
securities; U.S.  Government  securities  (including  zero  coupon  securities);
mortgage-backed  securities,  financial futures  contracts and  options thereon;
index options;  options  on  debt and  equity  securities;  private  placements;
repurchase  agreements; and reverse  repurchase agreements. In  addition, any or
all of the  above 35% of  total assets portion  of the Fund's  portfolio may  be
comprised of securities issued by foreign issuers.
 
    Pending investment of proceeds from the sale of shares of the Fund or of its
portfolio  securities or  at other times  when market conditions  dictate a more
"defensive" investment  strategy, the  Fund may  invest without  limit in  money
market  instruments, including commercial paper  of corporations organized under
the  laws  of  any  state  or  political  subdivision  of  the  United   States,
certificates  of deposit, bankers' acceptances and other obligations of domestic
banks or domestic  branches of foreign  banks, or foreign  branches of  domestic
banks,  in  each  case  having  total  assets  of  at  least  $500  million, and
obligations issued or  guaranteed by  the United States  Government, or  foreign
governments  or  their respective  instrumentalities or  agencies. The  yield on
these securities  will  generally tend  to  be lower  than  the yield  on  other
securities  to  be purchased  by  the Fund.  To  the extent  the  Fund purchases
Eurodollar certificates of deposit issued by foreign branches of domestic United
States banks, consideration will be  given to their domestic marketability,  the
lower  reserve requirements  normally mandated for  overseas banking operations,
the possible  impact of  interruptions  in the  flow of  international  currency
transactions  and economic developments which might adversely affect the payment
of principal or interest.
 
    All fixed-income securities are  subject to two types  of risks: the  credit
risk  and the interest rate risk. The credit  risk relates to the ability of the
issuer to  meet  interest  or principal  payments  or  both as  they  come  due.
Generally,  higher yielding  bonds are  subject to  a credit  risk to  a greater
extent than  higher  quality  bonds.  The  interest  rate  risk  refers  to  the
fluctuations  in net  asset value  of any  portfolio of  fixed-income securities
resulting solely  from  the inverse  relationship  between price  and  yield  of
fixed-income  securities;  that is,  when the  general  level of  interest rates
rises, the prices of outstanding
 
                                       6
<PAGE>

fixed-income securities generally decline, and when interest rates fall,  prices
generally rise. The Fund's yield will also vary based on the yield of the Fund's
portfolio securities.

 
    The  ratings of fixed-income securities by Moody's and Standard & Poor's are
a generally accepted barometer of credit risk. However, as the  creditworthiness
of  issuers of  lower-rated fixed-income  securities is  more problematical than
that of issuers of higher-rated fixed-income securities, the achievement of  the
Fund's  investment  objectives  will  be  more  dependent  upon  the  Investment
Manager's own  credit  analysis  than would  be  the  case with  a  mutual  fund
investing primarily in higher quality bonds. The Investment Manager will utilize
a   security's  credit   rating  as  simply   one  indication   of  an  issuer's
creditworthiness and will principally rely upon its own analysis of any security
currently held  by the  Fund or  potentially  purchasable by  the Fund  for  its
portfolio.
 
    In determining which securities to purchase or hold for the Fund's portfolio
and  in seeking to reduce credit and interest rate risks, the Investment Manager
will rely on  information from  various sources,  including: the  rating of  the
security;  research, analysis and  appraisals of brokers  and dealers, including
DWR; the views of the Fund's Trustees and others regarding economic developments
and interest rate trends; and the  Investment Manager's own analysis of  factors
it  deems relevant. The extent to which  the Investment Manager is successful in
reducing depreciation  or losses  arising from  either interest  rate or  credit
risks  depends in part  on the Investment  Manager's portfolio management skills
and judgment in  evaluating the factors  affecting the value  of securities.  No
assurance can be given regarding the degree of success that will be achieved.
 
RISK CONSIDERATIONS
 
    Because  of  the special  nature  of the  Fund's  investment in  high income
securities, commonly  known as  junk  bonds, the  Investment Manager  must  take
account of certain special considerations in assessing the risks associated with
such  investments. Although the  growth of the high  income securities market in
the 1980s had paralleled a long  economic expansion, recently many issuers  have
been affected by adverse economic and market conditions. It should be recognized
that  an economic  downturn or increase  in interest  rates is likely  to have a
negative effect on  the high income  bond market and  on the value  of the  high
income securities held by the Fund, as well as on the ability of the securities'
issuers to repay principal and interest on their borrowings.
 
    The prices of high income securities have been found to be less sensitive to
changes  in  prevailing interest  rates than  higher-rated investments,  but are
likely to be more sensitive to adverse economic changes or individual  corporate
developments.  During  an  economic  downturn or  substantial  period  of rising
interest rates, highly leveraged issuers  may experience financial stress  which
would  adversely affect  their ability to  service their  principal and interest
payment obligations,  to  meet  their  projected business  goals  or  to  obtain
additional financing. If the issuer of a fixed-income security owned by the Fund
defaults,  the Fund may incur additional expenses to seek recovery. In addition,
periods of  economic uncertainty  and change  can be  expected to  result in  an
increased   volatility  of  market  prices  of  high  income  securities  and  a
concomitant volatility in the net asset value of a share of the Fund.  Moreover,
the  market  prices of  certain  of the  Fund's  portfolio securities  which are
structured as  zero coupon  and  payment-in-kind securities  are affected  to  a
greater  extent by interest  rate changes and  thereby tend to  be more volatile
than securities which  pay interest  periodically and in  cash (see  "Dividends,
Distributions   and  Taxes"  for  a  discussion  of  the  tax  ramifications  of
investments in such securities).
 
    The secondary market for high income securities may be less liquid than  the
markets  for higher quality securities and, as  such, may have an adverse effect
on the market prices of certain securities. The limited liquidity of the  market
may   also   adversely   affect  the   ability   of  the   Fund's   Trustees  to
 
                                       7
<PAGE>
arrive at a fair value for certain  high income securities at certain times  and
could  make it difficult for  the Fund to sell  certain securities. In addition,
new laws and proposed new laws may have an adverse effect upon the value of high
income securities and a concomitant negative impact upon the net asset value  of
a share of the Fund.
 

    During  the fiscal  year ended March  31, 1997, the  monthly dollar weighted
average ratings  of  the debt  obligations  held by  the  Fund, expressed  as  a
percentage of the Fund's total investments, were as follows:

</TABLE>

 
    REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which
may  be viewed  as a type  of secured lending  by the Fund,  and which typically
involve the acquisition by the Fund of debt securities, from a selling financial
institution such as a bank, savings  and loan association or broker-dealer.  The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security at a specified price and at
a  fixed time in the future,  usually not more than seven  days from the date of
purchase. While repurchase agreements involve certain risks not associated  with
direct  investments  in  debt  securities, including  the  risks  of  default or
bankruptcy of the selling financial institution, the Fund follows procedures  to
minimize  such risks. These procedures include effecting repurchase transactions
only with large,  well-capitalized and  well-established financial  institutions
and maintaining adequate collateralization.
 
    WHEN-ISSUED  AND DELAYED DELIVERY SECURITIES  AND FORWARD COMMITMENTS.  From
time to  time,  in  the ordinary  course  of  business, the  Fund  may  purchase
securities  on a when-issued or  delayed delivery basis or  may purchase or sell
securities on a forward commitment basis. When such transactions are negotiated,
the price is fixed at the time  of the commitment, but delivery and payment  can
take place a month or more after the date of the commitment. While the Fund will
only   purchase  securities  on  a  when-issued,  delayed  delivery  or  forward
commitment basis with the  intention of acquiring the  securities, the Fund  may
sell  the securities before the settlement date,  if it is deemed advisable. The
securities so  purchased  or sold  are  subject  to market  fluctuation  and  no
interest  accrues  to  the purchaser  during  this  period. An  increase  in the
percentage of the  Fund's assets committed  to the purchase  of securities on  a
when-issued,  delayed  delivery or  forward  commitment basis  may  increase the
volatility of the Fund's net asset value.
 
    WHEN, AS AND IF ISSUED  SECURITIES.  The Fund  may purchase securities on  a
"when,  as and if issued" basis under which the issuance of the security depends
upon the  occurrence  of a  subsequent  event, such  as  approval of  a  merger,
corporate  reorganization,  leveraged  buyout  or  debt  restructuring.  If  the
anticipated event does  not occur and  the securities are  not issued, the  Fund
will  have lost  an investment  opportunity. There  is no  overall limit  on the
percentage of  the Fund's  assets which  may  be committed  to the  purchase  of
securities on a "when, as and if issued" basis. An increase in the percentage of
the  Fund's assets committed to the purchase of securities on a "when, as and if
issued" basis may increase the volatility of its net asset value.
 
    PRIVATE PLACEMENTS.  The Fund  may invest up to 10%  of its total assets  in
securities  which  are  subject  to restrictions  on  resale  because  they have
 
                                       8
<PAGE>
not  been  registered  under  the  Securities  Act  of  1933,  as  amended  (the
"Securities  Act"), or which  are otherwise not  readily marketable. (Securities
eligible for  resale  pursuant  to  Rule 144A  under  the  Securities  Act,  and
determined  to be liquid  pursuant to the procedures  discussed in the following
paragraph, are not subject to  the foregoing restriction.) These securities  are
generally   referred  to   as  private  placements   or  restricted  securities.
Limitations on the resale of such securities may have an adverse effect on their
marketability, and  may prevent  the Fund  from disposing  of them  promptly  at
reasonable  prices. The Fund  may have to  bear the expense  of registering such
securities for  resale and  the risk  of substantial  delays in  effecting  such
registration.
 
    The  Securities  and Exchange  Commission has  adopted  Rule 144A  under the
Securities Act,  which  permits  the  Fund  to  sell  restricted  securities  to
qualified  institutional  buyers  without  limitation.  The  Investment Manager,
pursuant to  procedures  adopted  by the  Trustees  of  the Fund,  will  make  a
determination  as to the liquidity of  each restricted security purchased by the
Fund. If a restricted security is determined to be "liquid", such security  will
not  be included within the category  "illiquid securities", which under current
policy may not exceed 15% of the  Fund's net assets. However, investing in  Rule
144A  Securities  could  have  the  effect  of  increasing  the  level  of  Fund
illiquidity to the extent the Fund, at a particular point in time, may be unable
to find qualified institutional buyers interested in purchasing such securities.
 
    REVERSE REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.   The  Fund may  also  use
reverse  repurchase  agreements  and  dollar rolls  as  part  of  its investment
strategy. Reverse repurchase agreements involve  sales by the Fund of  portfolio
assets  concurrently with an agreement by the Fund to repurchase the same assets
at a later date at a fixed price. The Fund may enter into dollar rolls in  which
the   Fund  sells   securities  and   simultaneously  contracts   to  repurchase
substantially similar (same type  and coupon) securities  on a specified  future
date.  Reverse repurchase agreements and dollar  rolls involve the risk that the
market value of  the securities the  Fund is obligated  to repurchase under  the
agreement  may decline  below the  repurchase price. In  the event  the buyer of
securities under  a  reverse  repurchase  agreement or  dollar  roll  files  for
bankruptcy or becomes insolvent, the Fund's use of proceeds of the agreement may
be  restricted pending  a determination  by the other  party, or  its trustee or
receiver, whether to enforce the Fund's obligation to repurchase the securities.
Reverse repurchase  agreements  and  dollar  rolls  are  speculative  techniques
involving leverage, and are considered borrowings by the Fund.
 
    ZERO  COUPON SECURITIES.  A portion of the fixed-income securities purchased
by the Fund may be  zero coupon securities. Such  securities are purchased at  a
discount from their face amount, giving the purchaser the right to receive their
full  value at maturity. The interest  earned on such securities is, implicitly,
automatically compounded and paid out at  maturity. While such compounding at  a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest  if  prevailing interest  rates  decline, the  owner  of a  zero coupon
security will be  unable to participate  in higher yields  upon reinvestment  of
interest  received on  interest-paying securities  if prevailing  interest rates
rise.
 
    A zero  coupon security  pays no  interest to  its holder  during its  life.
Therefore, to the extent the Fund invests in zero coupon securities, it will not
receive  current cash available  for distribution to  shareholders. In addition,
zero coupon securities are subject  to substantially greater price  fluctuations
during  periods  of  changing  prevailing  interest  rates  than  are comparable
securities which  pay interest  on  a current  basis.  Current federal  tax  law
requires  that a holder  (such as the Fund)  of a zero  coupon security accrue a
portion of the discount at which the security was purchased as income each  year
even  though the  Fund receives  no interest  payments in  cash on  the security
during the year.
 
    INVESTMENT IN REAL  ESTATE INVESTMENT TRUSTS.  The Fund may  invest in  real
estate investment trusts,
 
                                       9
<PAGE>
which  pool investors' funds for investments primarily in commercial real estate
properties. Investment  in  real  estate  investment  trusts  may  be  the  most
practical  available means for  the Fund to  invest in the  real estate industry
(the  Fund  is  prohibited  from  investing  in  real  estate  directly).  As  a
shareholder  in a real estate investment trust,  the Fund would bear its ratable
share of the real estate investment trust's expenses, including its advisory and
administration fees. At the  same time the  Fund would continue  to pay its  own
investment  management fees and other expenses as a result of which the Fund and
its stockholders  in effect  will be  absorbing duplicate  levels of  fees  with
respect to investments in real estate investment trusts.
 
    RIGHTS  AND WARRANTS.  The Fund may acquire rights and/or warrants which are
attached to  other  securities  in its  portfolio,  or  which are  issued  as  a
distribution  by the issuer of  a security held in  its portfolio. Rights and/or
warrants are, in  effect, options to  purchase equity securities  at a  specific
price, generally valid for a specific period of time, and have no voting rights,
pay  no dividends  and have  no rights with  respect to  the corporation issuing
them.
 
    CONVERTIBLE SECURITIES.  Among the fixed-income securities in which the Fund
may invest  are "convertible"  securities.  A convertible  security is  a  bond,
debenture, note, preferred stock or other security that may be converted into or
exchanged  for a prescribed  amount of common  stock of the  same or a different
issuer within  a particular  period of  time at  a specified  price or  formula.
Convertible  securities rank senior to common  stocks in a corporation's capital
structure and, therefore, entail less risk than the corporation's common  stock.
The value of a convertible security is a function of its "investment value" (its
value  as if it did not have a conversion privilege), and its "conversion value"
(the security's worth if it were to be exchanged for the underlying security, at
market value, pursuant to its conversion privilege). Fluctuations in the  prices
of  an  underlying  security  will  affect  the  conversion  value  and  cause a
concomitant fluctuation in the price of the convertible security.
 
    To the extent that a convertible security's investment value is greater than
its conversion  value,  its  price  will  be  primarily  a  reflection  of  such
investment  value and its price  will be likely to  increase when interest rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit standing of the issuer and other  factors may also have an effect on  the
convertible  security's value). If  the conversion value  exceeds the investment
value, the price  of the  convertible security  will rise  above its  investment
value  and, in addition,  will sell at  some premium over  its conversion value.
(This premium  represents  the  price  investors are  willing  to  pay  for  the
privilege  of purchasing a  fixed-income security with  a possibility of capital
appreciation due to the  conversion privilege.) At such  times the price of  the
convertible  security  will tend  to fluctuate  directly with  the price  of the
underlying equity security.
 
    Because of the special nature of  the Fund's permitted investments in  lower
rated  convertible  securities,  the  Investment Manager  must  take  account of
certain special  considerations  in assessing  the  risks associated  with  such
investments.  The prices of  lower rated securities  have been found  to be less
sensitive to changes in prevailing interest rates than higher rated investments,
but are likely to  be more sensitive to  adverse economic changes or  individual
corporate  developments. During  an economic  downturn or  substantial period of
rising interest rates, highly leveraged issuers may experience financial  stress
which  would  adversely  affect their  ability  to service  their  principal and
interest payment  obligations, to  meet  their projected  business goals  or  to
obtain additional financing. If the issuer of a lower rated convertible security
owned  by the  Fund defaults,  the Fund  may incur  additional expenses  to seek
recovery. In  addition,  periods  of  economic uncertainty  and  change  can  be
expected  to result in an  increased volatility of market  prices of lower rated
securities and a corresponding volatility in the  net asset value of a share  of
the Fund.
 
                                       10
<PAGE>
    FOREIGN SECURITIES.  The Fund may invest in securities of foreign companies.
Foreign  securities investments may be affected  by changes in currency rates or
exchange control regulations, change in governmental administration or  economic
or monetary policy (in the United States and abroad) or changed circumstances in
dealings  between nations. Costs will be incurred in connection with conversions
between various currencies held by  the Fund. Investments in foreign  securities
will also occasion risks relating to political and economic developments abroad,
including   the   possibility  of   expropriations  or   confiscatory  taxation,
limitations on the use  or transfer of  Fund assets and  any effects of  foreign
social, economic or political instability.
 
    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. The Fund may enter into forward
foreign  currency exchange  contracts ("forward  contracts") as  a hedge against
fluctuations in future foreign exchange rates. The Fund will conduct its foreign
currency exchange transactions either on a  spot (i.e., cash) basis at the  spot
rate  prevailing in  the foreign currency  exchange market,  or through entering
into forward  contracts  to  purchase  or sell  foreign  currencies.  A  forward
contract  involves an obligation  to purchase or  sell a specific  currency at a
future date, which may be any fixed number of days from the date of the contract
agreed upon by the parties, at a price  set at the time of the contract.  Should
forward  prices decline  during the  period between  the Fund's  entering into a
forward contract for the sale of a foreign currency and the date it enters  into
an  offsetting contract for the purchase of  the foreign currency, the Fund will
realize a gain to  the extent the price  of the currency it  has agreed to  sell
exceeds  the price  of the  currency it has  agreed to  purchase. Should forward
prices increase, the  Fund will suffer  a loss to  the extent the  price of  the
currency  it has  agreed to purchase  exceeds the  price of the  currency it has
agreed to sell.
 
    COMMON STOCKS.   The Fund may  directly purchase common  stocks on the  open
market.  In addition, the Fund may acquire  common stocks when they are included
in a unit with fixed-income securities purchased by the Fund; when  fixed-income
securities  held  by the  Fund are  converted  to equity  issues; when  the Fund
exercises a warrant; and when the  Fund purchases the common stock of  companies
involved in takeovers or recapitalization, where the issuer or a stockholder has
offered,   or  pursuant  to  a  "going  private"  transaction  is  effecting,  a
transaction involving the  issuance of newly  issued fixed-income securities  to
the holders of such common stock.
 
    The  prices  of  common stock  are  generally  more volatile  than  those of
fixed-income securities. Moreover, not all common stock pay dividends and  those
that  do generally pay lower amounts than most fixed-income securities. The Fund
will only purchase common stocks  directly when the Investment Manager  believes
that their purchase will assist the Fund in meeting its investment objectives.
 
    ADJUSTABLE RATE MORTGAGE SECURITIES.  The Fund may also invest in adjustable
rate  mortgage securities  ("ARMs"), which are  pass-through mortgage securities
collateralized by  mortgages  with  adjustable rather  than  fixed  rates.  ARMs
eligible  for inclusion in a mortgage pool generally provide for a fixed initial
mortgage interest  rate for  either the  first three,  six, twelve  or  thirteen
scheduled  monthly  payments.  Thereafter,  the interest  rates  are  subject to
periodic adjustment based on changes to a designated benchmark index.
 
    ARMs contain maximum and  minimum rates beyond  which the mortgage  interest
rate  may not vary over the lifetime  of the security. In addition, certain ARMs
provide for additional limitations on the  maximum amount by which the  mortgage
interest  rate  may  adjust  for any  single  adjustment  period. Alternatively,
certain ARMs contain limitations on changes in the required monthly payment.  In
the  event that a monthly payment is not sufficient to pay the interest accruing
on an ARM, any  such excess interest  is added to the  principal balance of  the
mortgage  loan, which is repaid through  future monthly payments. If the monthly
payment for such
 
                                       11
<PAGE>
an instrument exceeds the sum of the interest accrued at the applicable mortgage
interest rate and the principal payment  required at such point to amortize  the
outstanding principal balance over the remaining term of the loan, the excess is
utilized to reduce the then outstanding principal balance of the ARM.
 

OPTIONS AND FUTURES TRANSACTIONS

 
    The  Fund may purchase  and sell (write)  call and put  options on portfolio
securities which are denominated  in either U.S.  dollars or foreign  currencies
and on the U.S. dollar and foreign currencies, which are or may in the future be
listed  on  several U.S.  and  foreign securities  exchanges  or are  written in
over-the-counter transactions ("OTC options"). OTC options are purchased from or
sold (written)  to dealers  or financial  institutions which  have entered  into
direct agreements with the Fund.
 
    The  Fund is permitted to write covered call options on portfolio securities
and the U.S.  dollar and foreign  currencies, without limit,  in order to  hedge
against  the  decline in  the  value of  a security  or  currency in  which such
security is denominated, to  earn additional income and  to close out long  call
option  positions. The Fund may write covered  put options, under which the Fund
incurs an obligation  to buy the  security (or currency)  underlying the  option
from  the purchaser of the put at the option's exercise price at any time during
the option period, at the purchaser's election.
 
    The Fund  may  purchase listed  and  OTC call  and  put options  in  amounts
equalling  up to 5% of  its total assets. The Fund  may purchase call options to
close out a covered call position or to protect against an increase in the price
of a security it  anticipates purchasing or,  in the case of  call options on  a
foreign  currency,  to hedge  against  an adverse  exchange  rate change  of the
currency  in  which  the  security  it  anticipates  purchasing  is  denominated
vis-a-vis  the currency in which the exercise price is denominated. The Fund may
purchase put options on  securities which it holds  in its portfolio to  protect
itself  against a decline in the value of  the security and to close out written
put positions in a manner similar to call option closing purchase  transactions.
There  are  no other  limits  on the  Fund's ability  to  purchase call  and put
options.
 
    The Fund may purchase and sell futures contracts that are currently  traded,
or  may in  the future  be traded,  on U.S.  and foreign  commodity exchanges on
underlying portfolio securities, on any  currency ("currency" futures), on  U.S.
and  foreign  fixed-income  securities  ("interest rate"  futures)  and  on such
indexes of U.S.  or foreign equity  or fixed-income securities  as may exist  or
come  into being ("index" futures). The Fund  may purchase or sell interest rate
futures contracts for the  purpose of hedging  some or all of  the value of  its
portfolio  securities (or  anticipated portfolio securities)  against changes in
prevailing interest rates. The Fund may purchase or sell index futures contracts
for the  purpose  of  hedging some  or  all  of its  portfolio  (or  anticipated
portfolio)  securities against changes in their prices (or the currency in which
they are  denominated). As  a futures  contract purchaser,  the Fund  incurs  an
obligation  to take delivery of a  specified amount of the obligation underlying
the contract at  a specified  time in  the future for  a specified  price. As  a
seller  of a  futures contract,  the Fund  incurs an  obligation to  deliver the
specified amount of the underlying obligation at a specified time in return  for
an agreed upon price.
 
    The  Fund  also may  purchase  and write  call  and put  options  on futures
contracts which are traded  on an exchange and  enter into closing  transactions
with respect to such options to terminate an existing position.
 
    New  futures  contracts, options  and other  financial products  and various
combinations thereof continue to be developed.  The Fund may invest in any  such
futures,  options or products as may be developed, to the extent consistent with
its investment objective and applicable regulatory requirements.
 
    RISKS OF  OPTIONS AND  FUTURES  TRANSACTIONS. The  Fund  may close  out  its
position  as writer of an option, or as a buyer or seller of a futures contract,
 
                                       12
<PAGE>
only if a  liquid secondary market  exists for options  or futures contracts  of
that  series. There is no assurance that  such a market will exist, particularly
in the case of OTC options, as such options may generally only be closed out  by
entering  into a closing purchase transaction  with the purchasing dealer. Also,
exchanges may limit the amount by which the price of many futures contracts  may
move  on any day. If  the price moves equal the  daily limit on successive days,
then it may  prove impossible to  liquidate a futures  position until the  daily
limit moves have ceased.
 
    While the futures contracts and options transactions to be engaged in by the
Fund  for  the  purpose  of  hedging the  Fund's  portfolio  securities  are not
speculative in nature, there are risks inherent in the use of such  instruments.
One  such  risk  is  that  the Investment  Manager  could  be  incorrect  in its
expectations as to  the direction or  extent of various  interest rate or  price
movements  or the time span within which  the movements take place. For example,
if the Fund sold futures contracts for the sale of securities in anticipation of
an increase  in interest  rates,  and then  interest  rates went  down  instead,
causing  bond prices  to rise,  the Fund  would lose  money on  the sale  of the
futures contract. Another risk which  will arise in employing futures  contracts
to  protect against  the price  volatility of  portfolio securities  is that the
prices of securities, currencies and  indexes subject to futures contracts  (and
thereby the futures contract prices) may correlate imperfectly with the behavior
of  the U.S.  dollar cash  prices of the  Fund's portfolio  securities and their
denominated currencies.  See  the  Statement of  Additional  Information  for  a
further discussion of risks.
 
PORTFOLIO MANAGEMENT
 
    The  Fund's portfolio is  actively managed by its  Investment Manager with a
view  to  achieving  the  Fund's  investment  objective.  In  determining  which
securities  to  purchase for  the  Fund or  hold  in the  Fund's  portfolio, the
Investment Manager  will rely  on information  from various  sources,  including
research,  analysis and appraisals of brokers and dealers, including Dean Witter
Reynolds Inc. ("DWR"), a broker-dealer  affiliate of InterCapital, the views  of
Trustees  of the  Fund and others  regarding economic  developments and interest
rate trends,  and the  Investment Manager's  own analysis  of factors  it  deems
relevant.
 

    The  Fund is managed within InterCapital's Taxable Fixed-Income Group, which
manages 24 funds and fund portfolios,  with approximately $13 billion in  assets
at  May 31, 1997. Peter  M. Avelar, Senior Vice  President of InterCapital and a
member of  InterCapital's  Taxable  Fixed-Income Group,  has  been  the  primary
portfolio  manager of the Fund since its inception. Mr. Avelar has been managing
portfolios consisting of fixed-income and equity securities at InterCapital  for
over five years.

 
    Although  the Fund  does not engage  in substantial short-term  trading as a
means of achieving its  investment objective, it  may sell portfolio  securities
without regard to the length of time they have been held, in accordance with the
investment  policies described earlier.  Pursuant to an  order of the Securities
and Exchange Commission, the Fund  may effect principal transactions in  certain
money  market instruments  with DWR. In  addition, the Fund  may incur brokerage
commissions on transactions conducted  through DWR. Under normal  circumstances,
it  is not  anticipated that  the portfolio  trading will  result in  the Fund's
portfolio turnover rate  exceeding 200%  in any one  year. The  Fund will  incur
underwriting  discount costs  (on underwritten  securities) and  brokerage costs
commensurate with its portfolio turnover  rate. Short-term gains and losses  may
result  from  such  portfolio transactions.  See  "Dividends,  Distributions and
Taxes" for a discussion of the tax implications of the Fund's trading policy.

INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions  listed below are  among the restrictions  which
have  been adopted  by the  Fund as  fundamental policies.  Under the Investment
Company Act of 1940,  as amended (the  "Act"), a fundamental  policy may not  be
changed  without the vote of a majority  of the outstanding voting securities of
the Fund, as defined in the Act. For purposes of the following limitations:  (i)
all  percentage  limitations  apply  immediately  after  a  purchase  or initial
investment,  and  (ii)  any  subsequent  change  in  any  applicable  percentage
resulting  from market fluctuations or other changes in total or net assets does
not require elimination of any security from the portfolio.
 
    The Fund may not:
 
   1. As to 75%  of its total assets,  invest more than 5%  of the value of  its
total  assets in the securities of any one issuer (other than obligations issued
or   guaranteed   by   the   United   States   Government,   its   agencies   or
instrumentalities).
 
   2.  Invest 25%  or more  of the value  of its  total assets  in securities of
issuers in any  one industry.  This restriction  does not  apply to  obligations
issued   or  guaranteed  by  the  United  States  Government,  its  agencies  or
instrumentalities.
 
   3. Invest more  than 5% of  the value of  its total assets  in securities  of
issuers having a record, together with predecessors, of less than three years of
continuous  operation. This restriction shall not apply to any obligation issued
or   guaranteed   by   the   United   States   Government,   its   agencies   or
instrumentalities.
 
   4.  As to  75% of  its total  assets, purchase  more than  10% of  the voting
securities of any issuer.
 

    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.

 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    The  Fund offers its  shares for sale  to the public  on a continuous basis.
Pursuant  to  a  Distribution  Agreement  between  the  Fund  and  Dean   Witter
Distributors  Inc. (the "Distributor"), an  affiliate of the Investment Manager,
shares of the Fund  are distributed by  the Distributor and  offered by DWR  and
other  brokers and dealers who have entered into agreements with the Distributor
("Selected Broker-Dealers"). The principal  executive office of the  Distributor
is located at Two World Trade Center, New York, New York 10048.
    The minimum initial purchase is $1,000. Minimum subsequent purchases of $100
or  more may  be made  by sending a  check, payable  to Dean  Witter High Income
Securities, directly to Dean Witter Trust Company (the "Transfer Agent") at P.O.
Box 1040, Jersey City, NJ 07303 or by contacting an account executive of DWR  or
other  Selected  Broker-Dealer.  The minimum  initial  purchase in  the  case of
investments through  EasyInvest, an  automatic purchase  plan (see  "Shareholder
Services"),  is $100, provided  that the schedule  of automatic investments will
result in investments totalling at least $1,000 within the first twelve  months.
In  the  case  of investments  pursuant  to Systematic  Payroll  Deduction Plans
(including Individual Retirement Plans), the Fund, in its discretion, may accept
investments without  regard to  any  minimum amounts  which would  otherwise  be
required  if the  Fund has  reason to  believe that  additional investments will
increase the investment  in all accounts  under such Plans  to at least  $1,000.
Certificates for shares purchased will not be issued unless a request is made by
the shareholder in writing to the Transfer Agent. The offering price will be the
net  asset value per  share next determined  following receipt of  an order (see
"Determination of Net Asset Value").
 
                                       14
<PAGE>

    Shares of  the Fund  are sold  through  the Distributor  on a  normal  three
business day settlement basis; that is, payment is due on the third business day
(settlement  date) after the order is placed with the Distributor. Since DWR and
other Selected Broker-Dealers forward investors' funds on settlement date,  they
will  benefit  from the  temporary use  of the  funds if  payment is  made prior
thereto. As noted above, orders placed directly with the Transfer Agent must  be
accompanied  by payment. Investors will be  entitled to receive income dividends
and capital  gains distributions  if their  order is  received by  the close  of
business   on  the  day  prior  to  the  record  date  for  such  dividends  and
distributions. While  no  sales  charge  is  imposed  at  the  time  shares  are
purchased,  a contingent  deferred sales  charge may be  imposed at  the time of
redemption (see "Redemptions and Repurchases"). Sales personnel are  compensated
for  selling shares  of the Fund  at the time  of their sale  by the Distributor
and/or Selected Broker-Dealer. In addition, some sales personnel of the Selected
Broker-Dealer will receive  various types  of non-cash  compensation as  special
sales  incentives,  including trips,  educational  and/or business  seminars and
merchandise. The  Fund and  the  Distributor reserve  the  right to  reject  any
purchase orders.

 
    ANALOGOUS  DEAN WITTER  FUNDS.  The  Distributor and  the Investment Manager
serve in the  same capacities  for Dean Witter  High Yield  Securities Inc.,  an
open-end  investment company with investment  objectives and policies similar to
those of the Fund. Unlike  the Fund, however, shares  of Dean Witter High  Yield
Securities  Inc. are offered  to the public  with a sales  charge imposed at the
time of purchase, rather than a  contingent deferred sales charge assessed  upon
redemption  within  five years  of purchase.  These two  Dean Witter  Funds have
differing fees and expenses, which will affect performance. Investors who  would
like  to receive a prospectus for Dean  Witter High Yield Securities Inc. should
call the telephone numbers listed on the front cover of this Prospectus, or  may
call their account executive for additional information.
 
PLAN OF DISTRIBUTION
 
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act  (the "Plan"),  under which the  Fund pays  the Distributor a  fee, which is
accrued daily and payable monthly, at an annual rate of 0.80% of the lesser  of:
(a)  the average  daily aggregate  gross sales  of the  Fund's shares  since the
inception of the Fund (not including reinvestments of dividends or capital gains
distributions), less the average daily aggregate  net asset value of the  Fund's
shares  redeemed since  the Fund's  inception upon  which a  contingent deferred
sales charge has been  imposed or waived,  or (b) the  Fund's average daily  net
assets. This fee is treated by the Fund as an expense in the year it is accrued.
A  portion of the fee payable pursuant to the Plan, equal to 0.20% of the Fund's
average daily net assets, is characterized  as a service fee within the  meaning
of  NASD guidelines.  The service  fee is a  payment made  for personal services
and/or the maintenance of shareholder accounts.
 
    Amounts paid  under  the Plan  are  paid  to the  Distributor  for  services
provided   and  the  expenses  borne  by  the  Distributor  and  others  in  the
distribution of  the Fund's  shares, including  the payment  of commissions  for
sales  of the Fund's shares and incentive  compensation to and expenses of DWR's
account executives and others who engage in or support distribution of shares or
who service  shareholder accounts,  including overhead  and telephone  expenses;
printing  and distribution of  prospectuses and reports  used in connection with
the offering  of the  Fund's  shares to  other  than current  shareholders;  and
preparation,  printing  and  distribution of  sales  literature  and advertising
materials. In addition, the  Distributor may utilize fees  paid pursuant to  the
Plan  to compensate DWR and other  Selected Broker-Dealers for their opportunity
costs in advancing such amounts,  which compensation would be  in the form of  a
carrying charge on any unreimbursed expenses.
 
                                       15
<PAGE>

    For  the fiscal year ended  March 31, 1997, the  Fund accrued payments under
the Plan amounting to $6,228,452, which amount  is equal to 0.80% of the  Fund's
average  daily net assets  for the period.  The payments accrued  under the Plan
were calculated pursuant  to clause (b)  of the compensation  formula under  the
Plan.

 

    At  any given time the expenses of distributing shares of the Fund may be in
excess of the total of (i) the payments  made by the Fund pursuant to the  Plan,
and  (ii) the  proceeds of contingent  deferred sales charges  paid by investors
upon the  redemption of  shares  (see "Redemptions  and  Repurchases--Contingent
Deferred  Sales Charge"). For example, if $1 million in expenses in distributing
shares of the Fund had been incurred and $750,000 had been received as described
in (i)  and  (ii)  above, the  excess  expense  would amount  to  $250,000.  The
Distributor  has  advised  the  Fund  that  the  excess  distribution  expenses,
including the carrying charge described above, totalled $28,870,822 at March 31,
1997, which was equal to 2.56% of the Fund's net assets on such date.

 
    Because there  is no  requirement under  the Plan  that the  Distributor  be
reimbursed  for all  distribution expenses or  any requirement that  the Plan be
continued from year to year, such excess  amount, if any, does not constitute  a
liability of the Fund. Although there is no legal obligation for the Fund to pay
expenses  incurred in excess of payments made to the Distributor under the Plan,
and the proceeds  of contingent deferred  sales charges paid  by investors  upon
redemption of shares, if for any reason the Plan is terminated the Trustees will
consider at that time the manner in which to treat such expenses. Any cumulative
expenses incurred, but not yet recovered through distribution fees or contingent
deferred  sales charges, may or may not be recovered through future distribution
fees or contingent deferred sales charges.
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share of  the Fund is determined once daily at  4:00
p.m.,  New York time, (or, on days when the New York Stock Exchange closes prior
to 4:00 p.m., at such earlier time) on each day that the New York Stock Exchange
is open by  taking the  value of  all assets of  the Fund,  subtracting all  its
liabilities,  dividing by the number of  shares outstanding and adjusting to the
nearest cent. The  net asset  value per  share will  not be  determined on  Good
Friday and on such other federal and non-federal holidays as are observed by the
New York Stock Exchange.
 

    In  the calculation of the  Fund's net asset value:  (1) an equity portfolio
security listed or traded on  the New York or  American Stock Exchange or  other
domestic  or foreign stock exchange  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 a security
is traded on  more than one  exchange, the  security is valued  on the  exchange
designated  as  the  primary  market  pursuant  to  procedures  adopted  by  the
Trustees); and (2)  all other  portfolio securities  for which  over-the-counter
market quotations are readily available are valued at the latest bid price. When
market quotations are not readily available, including circumstances under which
it  is determined  by the Investment  Manager that  sale and bid  prices are not
reflective of  a security's  market value,  portfolio securities  are valued  at
their fair value as determined in good faith under procedures established by and
under the general supervision of the Board of Trustees.

 
    Short-term  debt securities with remaining maturities  of sixty days or less
at the  time of  purchase are  valued  at amortized  cost, unless  the  Trustees
determine  such does  not reflect  the securities'  market value,  in which case
these securities  will  be valued  at  their fair  value  as determined  by  the
Trustees.
 
    Certain  of  the Fund's  portfolio securities  may be  valued by  an outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a matrix  system incorporating  security  quality, maturity  and coupon  as  the
evaluation   model  parameters,  and/or  research   evaluations  by  its  staff,
 
                                       16

including review of broker-dealer market  price quotations, in determining  what
it  believes is the  fair valuation of  the portfolio securities  valued by such
pricing service.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    AUTOMATIC INVESTMENT OF DIVIDENDS AND  DISTRIBUTIONS.  All income  dividends
and  capital gains distributions  are automatically paid  in full and fractional
shares of the  Fund (or,  if specified by  the shareholder,  any other  open-end
investment   company  for  which  InterCapital   serves  as  investment  manager
(collectively, with the Fund, the "Dean Witter Funds")), unless the  shareholder
requests  that they be paid  in cash. Shares as acquired  are not subject to the
imposition of  a contingent  deferred sales  charge upon  their redemption  (see
"Redemptions and Repurchases").
 
    INVESTMENT OF DISTRIBUTIONS RECEIVED IN CASH. Any shareholder who receives a
cash  payment representing a  dividend or capital  gains distribution may invest
such dividend or distribution at the  net asset value per share next  determined
after  receipt by the Transfer Agent, by  returning the check or the proceeds to
the Transfer Agent within thirty days after the payment date. Shares so acquired
are not subject  to the imposition  of a contingent  deferred sales charge  upon
their redemption (see "Redemptions and Repurchases").
 
    EASYINVEST-SM-.    Shareholders may  subscribe  to EasyInvest,  an automatic
purchase plan  which  provides  for  any  amount  from  $100  to  $5,000  to  be
transferred automatically from a checking or savings account, on a semi-monthly,
monthly  or quarterly basis, to  the Transfer Agent for  investment in shares of
the   Fund   (see   "Purchase   of    Fund   Shares"   and   "Redemptions    and
Repurchases--Involuntary Redemption").
 
    SYSTEMATIC  WITHDRAWAL PLAN.  A  systematic withdrawal plan (the "Withdrawal
Plan") is available  for shareholders  who own or  purchase shares  of the  Fund
having  a minimum value of $10,000 based  upon the then current net asset value.
The Withdrawal Plan provides  for monthly or  quarterly (March, June,  September
and  December) checks in any  dollar amount, not less than  $25, or in any whole
percentage of  the  account balance,  on  an annualized  basis.  Any  applicable
contingent  deferred sales charge  will be imposed on  shares redeemed under the
Withdrawal Plan  (see "Redemptions  and Repurchases--Contingent  Deferred  Sales
Charge").  Therefore, any shareholder participating  in the Withdrawal Plan will
have sufficient shares  redeemed from his  or her account  so that the  proceeds
(net of any applicable contingent deferred sales charge) to the shareholder will
be the designated monthly or quarterly amount.
 
    Shareholders  should  contact  their  DWR  or  other  Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.
 
    TAX-SHELTERED RETIREMENT PLANS.  Retirement  plans are available for use  by
corporations,  the self-employed,  Individual Retirement  Accounts and Custodial
Accounts under Section 403(b)(7) of the Internal Revenue Code. Adoption of  such
plans should be on advice of legal counsel or tax adviser.
 
    For  further information  regarding plan administration,  custodial fees and
other details,  investors should  contact their  DWR or  other Selected  Broker-
Dealer account executive or the Transfer Agent.
 
EXCHANGE PRIVILEGE
 
    The  Fund  makes  available  to  its  shareholders  an  "Exchange Privilege"
allowing the exchange  of shares of  the Fund  for shares of  other Dean  Witter
Funds  sold  with a  contingent deferred  sales charge  ("CDSC funds"),  and for
shares of Dean Witter Short-Term  U.S. Treasury Trust, Dean Witter  Intermediate
Term  U.S. Treasury Trust, Dean Witter Short-Term Bond Fund, Dean Witter Limited
Term Municipal Trust,  Dean Witter  Balanced Growth Fund,  Dean Witter  Balanced
Income   Fund  and  five  Dean  Witter   Funds  which  are  money  market  funds
 
                                       17
<PAGE>
(the foregoing eleven non-CDSC funds are hereinafter collectively referred to as
the "Exchange  Funds"). Exchanges  may be  made  after the  shares of  the  Fund
acquired  by purchase (not by exchange  or dividend reinvestment) have been held
for thirty days. There is no waiting period for exchanges of shares acquired  by
exchange or dividend reinvestment.
 
    An exchange to another CDSC fund or to any Exchange Fund that is not a money
market  fund is on the basis of the next calculated net asset value per share of
each fund after  the exchange order  is received. When  exchanging into a  money
market  fund from the Fund, shares  of the Fund are redeemed  out of the Fund at
their next calculated  net asset value  and the proceeds  of the redemption  are
used  to  purchase shares  of the  money market  fund at  their net  asset value
determined the following business day.  Subsequent exchanges between any of  the
money  market funds and any of the CDSC funds can be effected on the same basis.
No contingent  deferred sales  charge ("CDSC")  is imposed  at the  time of  any
exchange, although any applicable CDSC will be imposed upon ultimate redemption.
Shares  of the Fund which are exchanged for shares of another CDSC fund having a
higher CDSC schedule than that of the Fund will be subject to the CDSC  schedule
of  the other CDSC fund, even if shares are subsequently re-exchanged for shares
of the Fund prior to redemption.  Concomitantly, shares of the Fund acquired  in
exchange  for shares of another CDSC fund having a lower CDSC schedule than that
of this Fund will  be subject to the  CDSC schedule of this  Fund, even if  such
shares  are subsequently  re-exchanged for  shares of  the CDSC  fund originally
purchased. During the  period of time  the shareholder remains  in the  Exchange
Fund  (calculated from  the last  day of  the month  in which  the Exchange Fund
shares were acquired), the  holding period (for the  purpose of determining  the
rate  of the CDSC) is  frozen. If those shares  are subsequently reexchanged for
shares of  a CDSC  fund, the  holding period  previously frozen  when the  first
exchange was made resumes on the last day of the month in which shares of a CDSC
fund  are  reacquired. Thus,  the CDSC  is  based upon  the time  (calculated as
described above) the shareholder was invested  in a CDSC fund (see  "Redemptions
and  Repurchases--Contingent Deferred  Sales Charge").  However, in  the case of
shares exchanged  into an  Exchange Fund  on or  after April  23, 1990,  upon  a
redemption  of shares which  results in a  CDSC being imposed,  a credit (not to
exceed the amount of the CDSC) will be given in an amount equal to the  Exchange
Fund  12b-1  distribution  fees  incurred  on  or  after  that  date  which  are
attributable to  those  shares.  (Exchange  Fund  12b-1  distribution  fees  are
described in the prospectuses for those funds.)
 
    In  addition, shares of the  Fund may be acquired  in exchange for shares of
Dean Witter Funds sold  with a front-end sales  charge ("front-end sales  charge
funds"),  but shares  of the  Fund, however acquired,  may not  be exchanged for
shares of  front-end sales  charge funds.  Shares  of a  CDSC fund  acquired  in
exchange  for shares of a front-end sales charge fund (or in exchange for shares
of other Dean Witter  Funds for which  shares of a  front-end sales charge  fund
have been exchanged) are not subject to any CDSC upon their redemption.
 
    Purchases  and  exchanges should  be made  for  investment purposes  only. A
pattern of frequent  exchanges may  be deemed by  the Investment  Manager to  be
abusive and contrary to the best interests of the Fund's other shareholders and,
at  the Investment Manager's discretion, may be limited by the Fund's refusal to
accept additional purchases and/  or exchanges from  the investor. Although  the
Fund  does not  have any  specific definition of  what constitutes  a pattern of
frequent exchanges,  and  will  consider all  relevant  factors  in  determining
whether  a particular situation is abusive and contrary to the best interests of
the Fund and its other shareholders, investors should be aware that the Fund and
each of the other Dean Witter Funds  may in their discretion limit or  otherwise
restrict  the number of  times this Exchange  Privilege may be  exercised by any
investor. Any such restriction will be made  by the Fund on a prospective  basis
only, upon notice to
 
                                       18
<PAGE>
the shareholder not later than ten days following such shareholder's most recent
exchange.  Also, the Exchange Privilege may be terminated or revised at any time
by the Fund and/or any  of such Dean Witter Funds  for which shares of the  Fund
have  been  exchanged,  upon  such  notice  as  may  be  required  by applicable
regulatory agencies.  Shareholders  maintaining  margin  accounts  with  DWR  or
another Selected Broker-Dealer are referred to their account executive regarding
restrictions on exchange of shares of the Fund pledged in the margin account.
 
    The  current prospectus for each  fund describes its investment objective(s)
and policies, and shareholders should obtain one and examine it carefully before
investing. Exchanges are subject to  the minimum investment requirement and  any
other  conditions imposed by each fund. In the case of any shareholder holding a
share certificate or  certificates, no  exchanges may  be made  until the  share
certificate(s)  have been  received by the  Transfer Agent and  deposited in the
shareholder's account.  An  exchange will  be  treated for  federal  income  tax
purposes  the  same  as a  repurchase  of  redemption of  shares,  on  which the
shareholder may realize a capital gain  or loss. However, the ability to  deduct
capital  losses on an  exchange may be  limited in situations  where there is an
exchange of  shares within  ninety  days after  the  shares are  purchased.  The
Exchange  Privilege is only available in states where an exchange may legally be
made.
 
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account  numbers  are part  of  the account  information,  shareholders  may
initiate  an exchange of shares of the Fund for shares of any of the Dean Witter
Funds (for which the Exchange Privilege is available) pursuant to this  Exchange
Privilege   by  contacting  their  account   executive  (no  Exchange  Privilege
Authorization Form is required). Other shareholders (and those shareholders  who
are  clients  of DWR  or  other Selected  Broker-Dealers  but who  wish  to make
exchanges directly by writing or  telephoning the Transfer Agent) must  complete
and  forward to  the Transfer  Agent an  Exchange Privilege  Authorization Form,
copies of  which  may  be obtained  from  the  Transfer Agent,  to  initiate  an
exchange. If the Authorization Form is used, exchanges may be made in writing or
by contacting the Transfer Agent at (800) 869-NEWS (toll-free).
 
    The  Fund  will  employ  reasonable  procedures  to  confirm  that  exchange
instructions communicated over  the telephone are  genuine. Such procedures  may
include requiring various forms of personal identification such as name, mailing
address,  social security  or other tax  identification number and  DWR or other
Selected Broker-Dealer account number (if any). Telephone instructions may  also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses due to unauthorized or fraudulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent  between 9:00 a.m. and 4:00  p.m., New York time, on  any day the New York
Stock Exchange is  open. Any  shareholder wishing to  make an  exchange who  has
previously  filed an Exchange Privilege Authorization  Form and who is unable to
reach the Fund  by telephone should  contact his  or her DWR  or other  Selected
Broker-Dealer  account  executive, if  appropriate, or  make a  written exchange
request. Shareholders are  advised that  during periods of  drastic economic  or
market  changes, it  is possible that  the telephone exchange  procedures may be
difficult to implement, although this has not been the experience with the  Dean
Witter Funds in the past.
 
    Shareholders  should  contact  their  DWR  or  other  Selected Broker-Dealer
account executive  or  the Transfer  Agent  for further  information  about  the
Exchange Privilege.

REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    REDEMPTION.   Shares of the Fund can be redeemed for cash at any time at the
net asset value per share next determined; however, such redemption proceeds may
be reduced by  the amount of  any applicable contingent  deferred sales  charges
(see  below). If  shares are  held in  a shareholder's  account without  a share
certificate, a written request  for redemption to the  Fund's Transfer Agent  at
P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by the
shareholder(s), the shares may be redeemed by surrendering the certificates with
a written request for redemption, along with any additional information required
by the Transfer Agent.
 
    CONTINGENT  DEFERRED SALES CHARGE.   Shares of  the Fund which  are held for
five years or more after purchase (calculated from the last day of the month  in
which  the  shares  were purchased)  will  not  be subject  to  any  charge upon
redemption. Shares redeemed sooner than five years after purchase may,  however,
be  subject to  a charge  upon redemption. This  charge is  called a "contingent
deferred sales  charge" ("CDSC"),  and it  will be  a percentage  of the  dollar
amount  of shares redeemed and will be assessed on an amount equal to the lesser
of the current market value or the  cost of the shares being redeemed. The  size
of  this percentage will depend upon how long  the shares have been held, as set
forth in the table below:
 
<TABLE>

                PURCHASE                   AS A PERCENTAGE OF
              PAYMENT MADE                  AMOUNT REDEEMED

Third...................................          2.0%
Fourth..................................          2.0%
Fifth...................................          1.0%
Sixth and thereafter....................          None
</TABLE>
 
    A CDSC will not be imposed on:  (i) any amount which represents an  increase
in  value of  shares purchased within  the five years  preceding the redemption;
(ii) the current net asset value of shares purchased more than five years  prior
to  the redemption; and  (iii) the current  net asset value  of shares purchased
through reinvestment of  dividends or  distributions and/or  shares acquired  in
exchange  for shares of Dean Witter Funds  sold with a front-end sales charge or
of other Dean Witter  Funds acquired in exchange  for such shares. Moreover,  in
determining  whether  a  CDSC is  applicable  it  will be  assumed  that amounts
described in (i), (ii) and (iii) above (in that order) are redeemed first.
 
    In addition, the CDSC, if otherwise  applicable, will be waived in the  case
of:
 
    (1)  redemptions of shares  held at the  time a shareholder  dies or becomes
disabled, only  if the  shares  are (A)  registered either  in  the name  of  an
individual  shareholder (not a trust),  or in the names  of such shareholder and
his or her spouse as joint tenants with right of survivorship, or (B) held in  a
qualified  corporate  or  self-employed retirement  plan,  Individual Retirement
Account or Custodial  Account under  Section 403(b)(7) of  the Internal  Revenue
Code,  provided in either case that the  redemption is requested within one year
of the death or initial determination of disability;
 
    (2)  redemptions   in  connection   with  the   following  retirement   plan
distributions: (A) lump-sum or other distributions from a qualified corporate or
self-employed  retirement plan  following retirement (or  in the case  of a "key
employee" of  a  "top heavy"  plan,  following attainment  of  age 59  1/2;  (B)
distributions  from an Individual Retirement  Account or Custodial Account under
Section 403(b)(7)  of the  Internal  Revenue Code  following attainment  of  age
59 1/2); and (C) a tax-free return of an excess contribution to an IRA; and
 
    (3)  all redemptions of  shares held for  the benefit of  a participant in a
corporate or self-employed retirement plan qualified under Section 401(k) of the
Internal  Revenue  Code  which  offers  investment  companies  managed  by   the
Investment  Manager  or  its  subsidiary,  Dean  Witter  Services  Company Inc.,
 
                                       20
<PAGE>

as self-directed investment alternatives and for which Dean Witter Trust Company
or Dean  Witter Trust  FSB, each  of which  is an  affiliate of  the  Investment
Manager, serves as Trustee or the 401(k) Support Services Group of DWR serves as
recordkeeper  ("Eligible  401(k)  Plan"),  provided that  either:  (A)  the plan
continues to  be  an Eligible  401(k)  Plan after  the  redemption; or  (B)  the
redemption  is in connection with the complete termination of the plan involving
the distribution of all plan assets to participants.

 
    With reference to (1) above, for the purpose of determining disability,  the
Distributor  utilizes the definition of disability contained in Section 72(m)(7)
of the  Internal Revenue  Code, which  relates  to the  inability to  engage  in
gainful  employment. With reference  to (2) above,  the term "distribution" does
not encompass a direct transfer of  IRA, 403(b) Custodial Account or  retirement
plan  assets to a  successor custodian or  trustee. All waivers  will be granted
only following receipt by the  Distributor of confirmation of the  shareholder's
entitlement.
 
    REPURCHASE.    DWR  and  other  Selected  Broker-Dealers  are  authorized to
repurchase shares represented by a share  certificate which is delivered to  any
of  their  offices.  Shares held  in  a  shareholder's account  without  a share
certificate may also  be repurchased  by DWR and  other Selected  Broker-Dealers
upon  the telephonic or  telegraphic request of  the shareholder. The repurchase
price is the net asset value next computed (see "Purchase of Fund Shares") after
such repurchase  order  is received  by  DWR or  other  Selected  Broker-Dealer,
reduced by any applicable CDSC.
 
    The  CDSC, if any, will be the only fee imposed by the Fund, the Distributor
or DWR or  other Selected  Broker-Dealer. The offer  by DWR  and other  Selected
Broker-Dealers  to  repurchase shares  may be  suspended  without notice  by the
Distributor at any  time. In that  event, shareholders may  redeem their  shares
through the Fund's Transfer Agent as set forth above under "Redemption."
 
    PAYMENT  FOR SHARES REDEEMED  OR REPURCHASED.   Payment for shares presented
for repurchase  or redemption  will be  made by  check within  seven days  after
receipt  by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended  under
unusual circumstances. If the shares to be redeemed have recently been purchased
by check, payment of the redemption proceeds may be delayed for the minimum time
needed  to verify that the check used  for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer  Agent).
Shareholders   maintaining  margin   accounts  with  DWR   or  another  Selected
Broker-Dealer are referred to their account executive regarding restrictions  on
redemption of shares of the Fund pledged in the margin account.
 
    REINSTATEMENT  PRIVILEGE.   A  shareholder  who has  had  his or  her shares
redeemed or  repurchased and  has not  previously exercised  this  reinstatement
privilege  may,  within  thirty  days  after  the  date  of  the  redemption  or
repurchase, reinstate any portion or all  of the proceeds of such redemption  or
repurchase  in shares of the Fund at their net asset value next determined after
a reinstatement request, together with the proceeds, is received by the Transfer
Agent and receive a pro-rata  credit for any CDSC  paid in connection with  such
redemption or repurchase.
 
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice,
to  redeem and  at net asset  value, the  shares of any  shareholder (other than
shares held  in an  Individual  Retirement Account  or Custodial  Account  under
Section  403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less  than $100 or such lesser amount as  may
be  fixed  by  the  Trustees  or,  in the  case  of  an  account  opened through
EasyInvest, if after twelve months the shareholder has invested less than $1,000
in the  account. However,  before the  Fund redeems  such shares  and sends  the
proceeds  to the shareholder, it  will notify the shareholder  that the value of
the shares is less than the applicable
 
                                       21
<PAGE>
amount and allow him or  her sixty days to make  an additional investment in  an
amount  which will  increase the  value of his  or her  account to  at least the
applicable amount before the redemption is processed. No CDSC will be imposed on
any involuntary redemption.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS AND DISTRIBUTIONS.   The Fund intends to  declare and pay  monthly
income  dividends and  to distribute  net short-term  and net  long-term capital
gains, if any, at least once each year. The Fund may, however, determine  either
to  distribute or to  retain all or part  of any long-term  capital gains in any
year for reinvestment.
 
    All dividends and  capital gains  distributions will be  paid in  additional
Fund   shares  (without  sales   charge)  and  automatically   credited  to  the
shareholder's account  without  issuance  of  a  share  certificate  unless  the
shareholder  requests in  writing that  all dividends be  paid in  cash and such
request is received by the close of business on the day prior to the record date
for such  distributions.  (See "Shareholder  Services--Automatic  Investment  of
Dividends and Distributions".)
 
    TAXES.   Because the  Fund intends to  distribute all of  its net investment
income and net capital gains to  shareholders and otherwise continue to  qualify
as  a regulated  investment company under  Subchapter M of  the Internal Revenue
Code, it is  not expected  that the  Fund will be  required to  pay any  Federal
income tax on such income and capital gains.
 
    With  respect to the  Fund's investments in  zero coupon and payment-in-kind
bonds, the  Fund accrues  income prior  to  any actual  cash payments  by  their
issuers.  In order to comply with Subchapter  M of the Internal Revenue Code and
be able to forego payment of Federal income tax on its income and capital gains,
the Fund must  distribute all  of its  net investment  income, including  income
accrued  from zero coupon  and payment-in-kind bonds.  As such, the  Fund may be
required to dispose of  some of its  portfolio securities under  disadvantageous
circumstances to generate the cash required for distribution.
 
    Shareholders  will  normally  have  to pay  Federal  income  taxes,  and any
applicable state and/or local income  taxes, on the dividends and  distributions
they receive from the Fund. Such dividends and distributions, to the extent they
are  derived from  net investment  income or  net short-term  capital gains, are
taxable to the shareholder as ordinary dividend income regardless of whether the
shareholder receives such  distributions in  additional shares or  in cash.  Any
dividends  declared in the last calendar quarter  of any year to shareholders of
record for that period which  are paid in the  following calendar year prior  to
February  1 will  be deemed  received by the  shareholder in  the prior calendar
year. Since the Fund's income is expected to be derived primarily from  interest
rather  than dividends,  only a  small portion,  if any,  of such  dividends and
distributions is  expected to  be eligible  for the  Federal dividends  received
deduction available to corporations.
 
    Distributions  of  net  long-term  capital gains,  if  any,  are  taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash. Capital  gains distributions are not eligible  for
the dividends received deduction. Capital gains may be generated by transactions
in options and futures contracts engaged in by the Fund.
 
    The  Fund may at times  make payments from sources  other than income or net
capital gains. Payments from such sources will, in effect, represent a return of
a portion of each shareholder's investment. All, or a portion, of such  payments
will not be taxable to shareholders.
 
    After the end of the calendar year, shareholders will receive a statement of
their  dividends  and capital  gains distributions  for tax  purposes, including
infor-
 
                                       22
<PAGE>
mation as to the portion taxable as  ordinary income and the portion taxable  as
capital gains.
 
    To  avoid being subject to  a 31% Federal backup  withholding tax on taxable
dividends, capital  gains  distributions and  the  proceeds of  redemptions  and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
 
    Shareholders  should consult their tax advisers regarding specific questions
as to state or local taxes and as to the applicability of the foregoing to their
current federal tax situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From time to time the Fund may  quote its "yield" and/or its "total  return"
in  advertisements and sales literature. Both the  yield and the total return of
the Fund  are based  on historical  earnings and  are not  intended to  indicate
future performance. The yield of the Fund is computed by dividing the Fund's net
investment  income over a 30-day  period by an average  value (using the average
number of shares entitled to receive dividends and the net asset value per share
at the  end  of  the  period), all  in  accordance  with  applicable  regulatory
requirements. Such amount is compounded for six months and then annualized for a
twelve-month period to derive the Fund's yield.
 
    The  "average annual total return" of the Fund refers to a figure reflecting
the average annualized  percentage increase  (or decrease)  in the  value of  an
initial  investment in the Fund  of $1,000 over one, five  and ten years, or the
life of the Fund, if less than any of the foregoing. Average annual total return
reflects all income earned by the Fund, any appreciation or depreciation of  the
Fund's  assets, all expenses incurred by the Fund and all sales charges incurred
by shareholders, for  the stated  period. It  also assumes  reinvestment of  all
dividends and distributions paid by the Fund.
 
    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time  by means of aggregate,  average, and year-by-year  or

ADDITIONAL INFORMATION

    VOTING RIGHTS.  All shares of beneficial  interest of the Fund are of  $0.01
par value and are equal as to earnings, assets and voting privileges.
 
    The  Fund is  not required  to hold Annual  Meetings of  Shareholders and in
ordinary circumstances  the Fund  does not  intend to  hold such  meetings.  The
Trustees  may call  Special Meetings of  Shareholders for  action by shareholder
vote as may be required  by the Act or the  Declaration of Trust. Under  certain
circumstances  the Trustees may be  removed by action of  the Trustees or by the
shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
circumstances, be  held personally  liable as  partners for  obligations of  the
Fund.  However,  the  Declaration of  Trust  contains an  express  disclaimer of
shareholder liability for acts  or obligations of the  Fund, requires that  Fund
obligations  include  such  disclaimer,  and  provides  for  indemnification and
reimbursement of expenses out  of the Fund's property  for any shareholder  held
personally  liable  for  the  obligations  of the  Fund.  Thus,  the  risk  of a
shareholder incurring  financial loss  on account  of shareholder  liability  is
limited to
 
                                       23
<PAGE>
circumstances  in which the Fund itself would be unable to meet its obligations.
Given the above limitations on shareholder personal liability, and the nature of
the Fund's assets and  operations, the possibility of  the Fund being unable  to
meet  its obligations is remote and, in  the opinion of Massachusetts counsel to
the Fund, the risk to Fund shareholders of personal liability is remote.
 
    CODE OF ETHICS.   Directors,  officers and employees  of InterCapital,  Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest,  that no undue personal benefit is obtained from a person's employment
activities and that actual and potential  conflicts of interest are avoided.  To
achieve  these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an  advance clearance process to monitor that  no
Dean  Witter Fund is engaged at the same time  in a purchase or sale of the same
security. The  Code of  Ethics bans  the purchase  of securities  in an  initial
public offering,
 
and also prohibits engaging in futures and options transactions and profiting on
short-term  trading (that is, a  purchase within sixty days of  a sale or a sale
within sixty  days  of  a  purchase) of  a  security.  In  addition,  investment
personnel  may not purchase or sell a security for their personal account within
thirty days before or after any transaction  in any Dean Witter Fund managed  by
them.  Any violations of the Code of  Ethics are subject to sanctions, including
reprimand, demotion  or suspension  or termination  of employment.  The Code  of
Ethics comports with regulatory requirements and the recommendations in the 1994
report by the Investment Company Institute Advisory Group on Personal Investing.
 

    MASTER/FEEDER  CONVERSION.  The  Fund reserves the right  to seek to achieve
its investment  objective  by  investing  all of  its  investable  assets  in  a
diversified,  open-end management investment company  having the same investment
objective and policies  and substantially  the same  investment restrictions  as
those applicable to the Fund.

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

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

<PAGE>
<TABLE>
<S>        <C>
BBB        Debt  rated BBB is regarded  as having an adequate  capacity to pay interest and
           repay principal. Whereas  it normally exhibits  adequate protection  parameters,
           adverse economic conditions or changing circumstances are more likely to lead to
           a  weakened  capacity to  pay  interest and  repay  principal for  debt  in this
           category than for debt in higher-rated categories.
           Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
BB         Debt rated BB has less near-term vulnerability to default than other speculative
           grade debt. However, it faces major ongoing uncertainties or exposure to adverse
           business, financial  or  economic  conditions which  could  lead  to  inadequate
           capacity to meet timely interest and principal payment.
B          Debt  rated  B has  a greater  vulnerability  to default  but presently  has the
           capacity to meet interest payments  and principal repayments. Adverse  business,
           financial  or economic conditions would likely impair capacity or willingness to
           pay interest and repay principal.
CCC        Debt rated  CCC has  a current  identifiable vulnerability  to default,  and  is
           dependent  upon favorable  business, financial  and economic  conditions to meet
           timely payments of interest and repayments of principal. In the event of adverse
           business, financial  or  economic conditions,  it  is  not likely  to  have  the
           capacity to pay interest and repay principal.
CC         The  rating CC is typically applied to debt subordinated to senior debt which is
           assigned an actual or implied CCC rating.
C          The rating C is typically applied to  debt subordinated to senior debt which  is
           assigned an actual or implied CCC- debt rating.
CI         The rating CI is reserved for income bonds on which no interest is being paid.
D          Debt  rated "D"  is in  payment default.  The "D"  rating category  is used when
           interest payments or principal payments are not made on the date due even if the
           applicable grace period has not expired, unless S&P believes that such  payments
           will be made during such grace period. The "D" rating also will be used upon the
           filing of a bankruptcy petition if debt service payments are jeopardized.
NR         Indicates  that  no  rating  has  been  requested,  that  there  is insufficient
           information on which to base a rating or that Standard & Poor's does not rate  a
           particular type of obligation as a matter of policy.
           Bonds  rated  BB,  B,  CCC,  CC  and  C  are  regarded  as  having predominantly
           speculative characteristics with respect to  capacity to pay interest and  repay
           principal. BB indicates the least degree of speculation and C the highest degree
           of  speculation. While  such debt will  likely have some  quality and protective
           characteristics, these  are  outweighed by  large  uncertainties or  major  risk
           exposures to adverse conditions.
           Plus  (+)  or minus  (-): The  ratings from  AA to  CCC may  be modified  by the
           addition of a  plus or minus  sign to  show relative standing  within the  major
           ratings categories.
           In  the case of municipal bonds, the foregoing ratings are sometimes followed by
           a "p"  which indicates  that the  rating is  provisional. A  provisional  rating
           assumes  the successful  completion of the  project being financed  by the bonds
           being rated and indicates that payment  of debt service requirements is  largely
           or  entirely dependent upon the successful and timely completion of the project.
           This rating, however, while addressing  credit quality subsequent to  completion
           of  the project,  makes no  comment on  the likelihood  or risk  of default upon
           failure of such completion.

<PAGE>
                            COMMERCIAL PAPER RATINGS
 
        Standard and Poor's commercial paper rating is a current  assessment
    of  the likelihood of timely payment of debt having an original maturity
    of no  more  than  365  days.  The commercial  paper  rating  is  not  a
    recommendation  to purchase  or sell a  security. The  ratings are based
    upon current information furnished by the issuer or obtained by S&P from
    other sources  it  considers  reliable.  The  ratings  may  be  changed,
    suspended,  or withdrawn as a result  of changes in or unavailability of
    such information. Ratings are graded into group categories, ranging from
    "A" for the highest quality obligations  to "D" for the lowest.  Ratings
    are  applicable  to both  taxable and  tax-exempt commercial  paper. The
    categories are as follows:
 
       Issues assigned  A  ratings  are  regarded  as  having  the  greatest
    capacity for timely payment. Issues in this category are further refined
    with  the designation  1, 2  and 3  to indicate  the relative  degree of
    safety.
 
<TABLE>
<S>        <C>
    A-1    indicates that the degree of safety regarding timely payment is very strong.
    A-2    indicates capacity for  timely payment  on issues with  this designation  is
           strong. However, the relative degree of safety is not as overwhelming as for
           issues designated "A-1".
    A-3    indicates  a satisfactory capacity for  timely payment. Obligations carrying
           this designation  are,  however, somewhat  more  vulnerable to  the  adverse
           effects  of changes  in circumstances  than obligations  carrying the higher
           designations.

DEAN WITTER HIGH INCOME SECURITIES  TWO WORLD TRADE CENTER, NEW YORK, NEW YORK
                                    10048

LETTER TO THE SHAREHOLDERS MARCH 31, 1997
 
DEAR SHAREHOLDER:
 
The high-yield market posted solid returns during the past twelve months and
outperformed most of the other fixed-income markets. With the economy rebounding
from its late 1995 weakness and with corporate earnings holding up well during
the year, the market was able to offset what was a relatively weak fixed-income
environment.
 
In early 1996, investors were anticipating a recession, due to concern over a
then-weakening economy. U.S. Treasury yields were lower than today's levels,
with yields in the high-yield market higher. As the year played out, we saw the
economy bounce back, corporate earnings hold up, the equity markets reach
all-time highs and recession fears ease. The result was a somewhat weak and
volatile U.S. Treasury market, while the high-yield market held up well, given
the stronger than expected economy. Although yield spreads narrowed during the
year, many B-rated issues still provide an attractive yield advantage (nearly
400 basis points) over U.S. Treasuries and trade at or below par.
 
As Dean Witter High Income Securities begins its new fiscal year, a correction
is under way across most of the financial markets, including the high-yield bond
sector. On the heels of a credit tightening by the Federal Reserve Board in late
March, considerable nervousness has been evident in both the equity and
fixed-income markets. Speculation as to the timing and impact of any further
increases in interest rates has created uncertainty on the part of many
investors. The high-yield market also has felt this weakness, as investors
attempt to discount the possibility of slowing in the economy within the context
of any further tightening by the Federal Reserve Board.
 
PERFORMANCE AND PORTFOLIO STRATEGY
 
Against this backdrop, Dean Witter High Income Securities produced a total
return of 10.71 percent for the twelve-month period ended March 31, 1997, based
on its net asset value (NAV) of $9.80 per share plus reinvestment of dividends
and capital gains distributions. This compares to returns of 10.64 percent for
the Lehman High Yield Index
<PAGE>
DEAN WITTER HIGH INCOME SECURITIES
LETTER TO THE SHAREHOLDERS MARCH 31, 1997, CONTINUED
 
and a return of 10.30 percent for the Lipper High Yield Bond Fund Index during
the same period. Over the past twelve months, the Fund continued to distribute
regular income dividends at a rate of $0.08 per share per month. For the full
twelve-month period, the Fund's distributions totaled approximately $1.14 per
share, including an extra income dividend of $0.068 per share and capital gain
distributions of $0.106011 per share. On March 31, 1997, the Fund's net assets
exceeded $1.1 billion. The accompanying chart illustrates the growth of a
$10,000 investment in the Fund since inception (June 2, 1994) through the fiscal
year ended March 31, 1997, compared to a similar investment in the issues that
comprise the Lehman Brothers Mutual Fund Corporate/High Yield Index, the Lehman
Brothers High Yield Index and the Lipper High Yield Bond Funds Index.
(Note: We will be changing the
benchmark that we measure the Fund's                [GRAPHIC]
performance against from the Lehman
Brothers Mutual Fund Corporate/High
Yield Index to the Lehman Brothers High
Yield Index, which represents the
Fund's portfolio composition more
accurately.)
 
As the economy has continued to expand
over the past few years, we have tended
to concentrate on B-rated issues. In a
growing economy one can find
undervalued "upgrade" candidates in
this sector of the market that provide
attractive yields as well as
appreciation potential. We therefore
continue to feel that many of these
issues are very attractive long-term
investments. However, given today's
higher interest rate environment and a
potentially slowing economy down the
road, we have recently taken some
defensive steps with the portfolio.
Over the past six to nine months, we
have upgraded the portfolio by
increasing our allocation to the
higher-quality end of the market
(BB-rated issues or higher) from 10
percent to 25 percent. We also sold
many of our heavily cyclical positions
and are now focused mainly on the more
predictable recession-resistant or
growth sectors of the economy. These
are areas which would tend to hold up
well in an
<PAGE>

economic slowdown. In certain of these sectors, such as media and
telecommunications, we expect to see continued consolidation, which should bode
well for most industry participants, including many of the portfolio's current
holdings.
 
LOOKING AHEAD
 
Overall, we continue our primary focus on discounted B-rated investments
yielding 10 percent or higher, which we feel possess appreciation potential as
well as an attractive yield. In addition, while we are not expecting a recession
in 1997, we have begun to take a more defensive approach in case of any economic
slowing down the road as a result of today's higher interest rate environment.
 
We thank you for your continued support of Dean Witter High Income Securities
and look forward to continuing to serve your investment needs.
 
Very truly yours,

DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter High Income Securities (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's primary investment objective
is to earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund
seeks to achieve its objective by investing primarily in lower-rated fixed
income securities. The Fund was organized as a Massachusetts business trust on
March 23, 1994 and commenced operations on June 2, 1994.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) 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 a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (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
and bid prices are not reflective of a security's market value, portfolio
securities are valued at their fair value as determined in good faith under
procedures established by and under the general supervision of the 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 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
<PAGE>
DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
on a mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.
 
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 ex-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.
 
E. ORGANIZATIONAL EXPENSES -- The Investment Manager paid the organizational
expenses of the Fund in the amount of approximately $154,000 which haven been
reimbursed for the full amount thereof. Such expenses have been deferred and are
being amortized on the straight-line method over a period not to exceed five
years from the commencement of operations.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, calculated daily and payable monthly, by applying the
annual rate of 0.50% to the net assets of the Fund determined as of the close of
each business day. Effective May 1, 1996, the annual rate was reduced to 0.425%
for net assets in excess of $500 million.
<PAGE>
DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
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 pursuant
to which the Fund pays the Distributor compensation, accrued daily and payable
monthly, at an annual rate of 0.80% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's shares since the Fund's inception (not
including reinvestment of dividend or capital gain distributions) less the
average daily aggregate net asset value of the Fund's shares redeemed since the
Fund's inception upon which a contingent deferred sales charge has been imposed
or upon which such charge has been waived; or (b) the Fund's average daily net
assets. Amounts paid under the Plan are paid to the Distributor to compensate it
for the services provided and the expenses borne by it and others in the
distribution of the Fund's shares, including the payment of commissions for
sales of the Fund's shares and incentive compensation to, and expenses of, the
account executives of Dean Witter Reynolds Inc., an affiliate of the Investment
Manager and Distributor, and other employees or selected broker-dealers who
engage in or support distribution of the Fund's shares or who service
shareholder accounts, including overhead and telephone expenses, printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may be compensated under the Plan for its opportunity costs in
advancing such amounts, which compensation would be in the form of a carrying
charge on any unreimbursed expenses incurred by the Distributor.
 
Provided that the Plan continues in effect, any cumulative expenses incurred but
not yet recovered may be recovered through future distribution fees from the
Fund and contingent deferred sales charges from the Fund's shareholders.
 
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
<PAGE>

NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
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 $28,870,822 at March 31, 1997.
 
The Distributor has informed the Fund that for the year ended March 31, 1997, it
received approximately $1,408,000 in contingent deferred sales charges from
certain redemptions of the Fund's shares.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended March 31, 1997 aggregated
$882,695,717 and $301,847,787, respectively.
 
Dean Witter Trust Company, an affiliate of the Investment Manager and the
Distributor, is the Fund's transfer agent. At March 31, 1997, the Fund had
transfer agent fees and expenses payable of approximately $66,000.
 
5. SHARES OF BENEFICIAL INTEREST
 
Transactions in shares of beneficial interest were as follows:

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER HIGH INCOME SECURITIES
 
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 High Income Securities
(the "Fund") at March 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 two years in the period
then ended and for the period June 2, 1994 (commencement of operations) through
March 31, 1995, 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 March
31, 1997 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

                    DEAN WITTER HIGH YIELD SECURITIES INC. 
                   NOTES TO PRO FORMA FINANCIAL STATEMENTS 
                                 (UNAUDITED) 

1. BASIS OF COMBINATION -- The Pro Forma Statement of Assets and Liabilities, 
including the Portfolio of Investments, at March 31, 1997 and the related 
Statement of Operations ("Pro Forma Statements") for the twelve months ended 
March 31, 1997, reflect the accounts of Dean Witter High Yield Securities 
Inc. ("High Yield") and Dean Witter High Income Securities ("High Income"). 

The Pro Forma Statements give effect to the proposed transfer of all assets 
and liabilities of High Income in exchange for shares in High Yield. The Pro 
Forma Statements should be read in conjunction with the historical financial 
statements of each Fund included in its Prospectus or Statement of Additional 
Information. 

2. FUND SHARES TRANSACTIONS -- The pro forma net asset value per share 
assumes the issuance of additional shares of High Yield which would have been 
issued on March 31, 1997 in connection with the proposed reorganization. The 
amount of additional shares assumed to be issued (171,854,015) was calculated 
based on the March 31, 1997 net assets of High Income ($1,129,080,877) and 
the net asset value per share of High Yield ($6.57). 

3. PRO FORMA OPERATIONS -- On July 28, 1997, High Yield will begin offering 
four classes of shares. Class B shares of High Yield will be issued to High 
Income shareholders and High Yield shareholders will be issued Class D 
shares. 

The Pro Forma Statement of Operations assumes similar rates of gross 
investment income for the investments of each Fund. Accordingly, the combined 
gross investment income is equal to the sum of each Fund's gross investment 
income. Certain expenses have been adjusted to reflect the expected expenses 
of the combined entity. The Statement of Operations includes the actual 
operating expenses of the Funds and the pro forma expenses of the combined 
Fund based on the fee schedule in effect for High Yield at the combined level 
of average net assets for the twelve months ended March 31, 1997 except for 
the plan of distribution, the expenses of which are based on the proposed fee 
schedule for Class B shares of High Yield. It is intended that the combined 
Fund will bear all of its expenses. Pro forma operating expenses do not 
include the impact of estimated solicitation costs in connection with the 
reorganization, which will be paid by Dean Witter InterCapital Inc, the 
Investment Manager of both High Yield and High Income. 

High Yield has a capital loss carryover of approximately $937 million and a 
net unrealized loss of approximately $80 million. Most of those 
built-in-losses and capital loss carryovers will not be available to offset 
realized capital gains of the combined fund. Only a portion of the unrealized 
capital losses and capital loss carryovers (i.e., approximately $27 million 
per year for seven years) will be available to offset realized net capital 
gains of the combined fund. After seven years, the unused loss carryover will 
be eliminated. To reflect the approximate limitation on the use of the 
carryover losses, paid-in-capital was charged $780,000,000 and accumulated 
net realized loss was credited $780,000,000.

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
 
    The Fund was incorporated under Maryland law on June 14, 1979, under the
name InterCapital High Yield Securities Inc. On March 16, 1983, the Fund's
shareholders approved a change in the Fund's name, effective March 21, 1983, to
Dean Witter High Yield Securities Inc.
 
THE INVESTMENT MANAGER
 

    Dean Witter InterCapital Inc. (the "Investment Manager" or "InterCapital"),
a Delaware corporation, whose address is Two World Trade Center, New York, New
York 10048, is the Fund's Investment Manager. InterCapital is a wholly-owned
subsidiary of 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
Reynolds Inc. ("DWR"), a broker-dealer affiliate of InterCapital. (As
hereinafter used in this Statement of Additional Information, the terms
"InterCapital" and "Investment Manager" refer to DWR's InterCapital Division
prior to the internal reorganization and to Dean Witter InterCapital Inc.
thereafter.) The daily management of the Fund 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
Directors. Information as to these Directors and officers is contained under the
caption "Directors and Officers."

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

Emerging Markets Opportunites 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 objectives and policies.
 
    Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, such office space, facilities,
equipment, clerical help and bookkeeping and certain legal services as the Fund
may reasonably require in the conduct of its business, including the preparation
of prospectuses, statements of additional information, proxy statements and
reports required to be filed with federal and state securities commissions
(except insofar as the participation or assistance of independent accountants
and attorneys is, in the opinion of the Investment Manager, necessary or
desirable). In addition, the Investment Manager pays the salaries of all
personnel, including officers of the Fund, who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone service, heat,
light, power and other utilities provided to the Fund.
 
    Effective December 31, 1993, pursuant to a Services Agreement between
InterCapital and DWSC, 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 that date. The
foregoing internal reorganization 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 assets of the Fund attributable
to each Class, except as described below. The expenses borne by the Fund
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 stock 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 of the Fund and supplements thereto to the Fund's shareholders; all
expenses of shareholders' and directors' meetings and of preparing, printing and
mailing of proxy statements and reports to shareholders; fees and travel
expenses of directors or members of any advisory board or committee who are not
employees of the Investment Manager or any corporate affiliate of the Investment

 
                                        4

Manager; all expenses incident to any dividend, distribution, withdrawal or
redemption options; charges and expenses of any outside service used for pricing
of the Fund's shares; fees and expenses of legal counsel, including counsel to
directors 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 directors) of the Fund which
inure to its benefit; extraordinary expenses (including, but not limited to,
legal claims and liabilities and litigation costs and any indemnification
relating thereto); and all other costs of the Fund's operation. The 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 Directors.

 

    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 net assets of the Fund determined as of the close
of each business day: 0.50% of the portion of the daily net assets not exceeding
$500 million; 0.425% of the portion of the daily net assets exceeding $500
million but not exceeding $750 million; 0.375% of the portion of the daily net
assets exceeding $750 million but not exceeding $1 billion; 0.35% of the portion
of the daily net assets exceeding $1 billion but not exceeding $2 billion;
0.325% of the portion of daily net assets exceeding $2 billion but not exceeding
$3 billion; and 0.30% of the portion of daily net assets exceeding $3 billion.
Total compensation accrued to the Investment Manager for the Fund's fiscal years
ended August 31, 1994, 1995 and 1996 amounted to $2,690,898, $2,241,952 and
$2,271,578, 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 Directors 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 Directors on
October 30, 1992 and by the shareholders of the Fund at a Special Meeting of
Shareholders held on January 12, 1993. 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 Board of Directors of the Fund, by the holders of
a majority, as defined in the Investment Company Act of 1940, as amended (the
"Act"), of the outstanding shares of the Fund, 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 has an initial term ending April 30, 1999,
and will remain in effect from year to year thereafter, provided continuation 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 Board of Directors of the Fund; provided that in either event such
continuance is approved annually by the vote of a majority of the Directors of
the Fund who are not parties to the Agreement or "interested persons" (as
defined in the Act) of any such party (the "Independent Directors"), 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 between InterCapital and the Fund is terminated, or if
the affiliation between InterCapital and its parent company is terminated, the
Fund will eliminate the name "Dean Witter" from its name if DWR or its parent
company shall so request.

Carsten Otto and Ruth Rossi, Vice Presidents and Assistant General Counsels of
InterCapital and DWSC, and Frank Bruttomesso, a staff attorney with
InterCapital, are also Assistant Secretaries of the Fund.

 
THE BOARD OF DIRECTORS, THE INDEPENDENT DIRECTORS, AND THE COMMITTEES
 

    The Board of Directors currently consists of eight (8) directors; as noted
above, Mr. Hedien's term will commence on September 1, 1997. These same
individuals also serve as directors or trustees for all of the Dean Witter
Funds, and are referred to in this section as Directors. As of the date of this
Statement of Additional Information, there are a total of 83 Dean Witter Funds,
comprised of 126 portfolios. As of June 30, 1997, the Dean Witter Funds had
total net assets of approximately $  billion and more than six million
shareholders.

 

    Six Directors and Mr. Hedien (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" Directors. The other two
Directors (the "management Directors") are affiliated with InterCapital. Four of
the six independent Directors are also Independent Trustees of the TCW/DW Funds.

 
    Law and regulation establish both general guidelines and specific duties for
the Independent Directors. The Dean Witter Funds seek as Independent Directors
or Trustees individuals of distinction and experience in business and finance,
government service or academia; these are people whose advice and counsel are in
demand by others and for whom there is often competition. To accept a position
on the Funds' Boards, such individuals may reject other attractive assignments
because the Funds make substantial demands on their time. Indeed, by serving on
the Funds' Boards, certain Directors or 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 current Independent Directors serve as members of the Audit
Committee and the Committee of the Independent Directors. 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 Directors 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 Directors 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
 
                                        8
<PAGE>

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 Directors are required to select and nominate
individuals to fill any Independent Director 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 DIRECTORS AND AUDIT COMMITTEE
 
    The Chairman of the Committee of the Independent Directors 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 Directors 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 Directors 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 Directors.
 

    The Chairman of the Committee of the Independent Directors 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
Director of the Dean Witter Funds and as an Independent Director 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 DIRECTORS FOR ALL DEAN
WITTER FUNDS

 

    The Independent Directors and the Funds' management believe that having the
same Independent Directors for each of the Dean Witter Funds avoids the
duplication of effort that would arise from having different groups of
individuals serving as Independent Directors for each of the Funds or even of
sub-groups of Funds. They believe that having the same individuals serve as
Independent Directors 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 Directors 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 Directors serve on all Fund

 
                                        9
<PAGE>


Boards enhances the ability of each Fund to obtain, at modest cost to each
separate Fund, the services of Independent Directors, and a Chairman of their
Committees, of the caliber, experience and business acumen of the individuals
who serve as Independent Directors of the Dean Witter Funds.

 

COMPENSATION OF INDEPENDENT DIRECTORS

 
    The Fund pays each Independent Director an annual fee of $1,000 plus a per
meeting fee of $50 for meetings of the Board of Directors or committees of the
Board of Directors attended by the Director (the Fund pays the Chairman of the
Audit Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent Directors an additional annual fee of $1,200). The Fund also
reimburses such Directors for travel and other out-of-pocket expenses incurred
by them in connection with attending such meetings. Directors 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 Directors by the Fund for the fiscal year ended August 31, 1996.

With respect to Messrs. Haire, Johnson, Nugent and Schroeder, the TCW/DW Funds
are included solely because of a limited exchange privilege between those Funds
and five Dean Witter Money Market Funds.

    As of the date of this Statement of Additional Information, 57 of the Dean
Witter Funds, including the Fund, have adopted a retirement program under which
an Independent Director 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 Director referred to
as an "Eligible Director") 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 Director
is entitled to receive from the Adopting Fund, commencing as of his or her
retirement date and continuing


                                       10
<PAGE>


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 Director for service to the Adopting Fund in the five
year period prior to the date of the Eligible Director'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 Directors by the Fund for the fiscal year ended August 31,
1996 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
Directors, to commence upon their retirement, from the Fund as of August 31,
1996 and from the 57 Dean Witter Funds as of December 31, 1996.

(1) An Eligible Director may elect alternate payments of his or her retirement
    benefits based upon the combined life expectancy of such Eligible Director
    and his or her spouse on the date of such Eligible Director's retirement.
    The amount estimated to be payable under this method, through the remainder
    of the later of the lives of such Eligible Director and spouse, will be the
    actuarial equivalent of the Regular Benefit. In addition, the Eligible
    Director 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 Director's elections described in Footnote (1)
    above.

    As of the date of this Statement of Additional Information, the aggregate
number of shares of beneficial interest of the Fund owned by the Fund's officers
and Directors as a group was less than 1 percent of the Fund's shares of
beneficial interest outstanding.
 
INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund will invest principally in
fixed-income securities rated Baa or lower by Moody's Investor's Service Inc.
("Moody's"), or BBB or lower by Standard & Poor's Corporation ("Standard &
Poor's"). The ratings of fixed-income securities by Moody's and Standard &
Poor's are a generally accepted barometer of credit risk. They are, however,
subject to certain limitations from an investor's standpoint.
 
    Such limitations include the following: the rating of an issuer is heavily
weighted by past developments and does not necessarily reflect probable future
conditions; there is frequently a lag between the time a rating is assigned and
the time it is updated; and there may be varying degrees of difference in credit
risk of securities in each rating category. The Investment Manager will attempt
to reduce the overall portfolio credit risk through diversification and
selection of portfolio securities based on considerations mentioned below.
 
                                       11
<PAGE>

    While the ratings provide a generally useful guide to credit risks, they do
not, nor do they purport to, offer any criteria for evaluating the interest rate
risk. Changes in the general level of interest rates cause fluctuations in the
prices of fixed-income securities already outstanding and will therefore result
in fluctuation in net asset value of the Fund's shares. The extent of the
fluctuation is determined by a complex interaction of a number of factors. The
Investment Manager will evaluate those factors it considers relevant and will
make portfolio changes when it deems it appropriate in seeking to reduce the
risk of depreciation in the value of the Fund's portfolio. However, in seeking
to achieve the Fund's primary objective, there will be times, such as during
periods of rising interest rates, when depreciation and realization of capital
losses on securities in the portfolio will be unavoidable. Moreover, medium and
lower-rated securities and non-rated securities of comparable quality tend to be
subject to wider fluctuations in yield and market values than higher rated
securities. Such fluctuations after a security is acquired do not affect the
cash income received from that security but are reflected in the net asset value
of the Fund's portfolio.
 
PORTFOLIO CHARACTERISTICS
 
    Lending of Portfolio Securities.  Consistent with applicable regulatory
requirements and subject to Investment Restriction 8 below, the Fund may lend
its portfolio securities to brokers, dealers and other financial institutions,
provided that such loans are callable at any time by the Fund (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 day's notice, or by
the Fund on four business days' notice. If the borrower fails to deliver the
loaned securities within four days after receipt of notice, the Fund could use
the collateral to replace the securities while holding the borrower liable for
any excess of replacement cost over the value of the collateral. As with any
extensions of credit, there are risks of delay in recovery and, in some cases,
even loss of rights in the collateral should the borrower of the securities fail
financially. However, these loans of portfolio securities will only be made to
firms deemed by the Fund's management to be creditworthy and when the income
which can be earned from such loans justifies the attendant risks. Upon
termination of the loan, the borrower is required to return the securities to
the Fund. Any gain or loss in the market price during the loan period would
inure to the Fund. The creditworthiness of firms to which the Fund lends its
portfolio securities will be monitored on an ongoing basis by the Investment
Manager pursuant to procedures adopted and reviewed, on an ongoing basis, by the
Board of Directors 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, in
whole or in part as may be appropriate, to be delivered within one day after
notice, to permit the exercise of such rights if the matters involved would have
a material effect on the Fund's investment in such loaned securities. The Fund
will pay reasonable finder's, administrative and custodial fees in connection
with a loan of its securities. The Fund did not lend any of its portfolio
securities during its fiscal year ended August 31, 1996.
 
    Repurchase Agreements.  When cash may be available for only a few days, it
may be invested by the Fund in repurchase agreements until such time as it may
otherwise be invested or used for payments of obligations of the Fund. These
agreements, which may be viewed as a type of secured lending by the Fund,
typically involve the acquisition by the Fund of debt securities from a selling
financial institution such as a bank, savings and loan association or
broker-dealer. The agreement provides that the Fund will sell back to the
institution, and that the institution will repurchase, the underlying security
("collateral"), which is held by the Fund's Custodian, at a specified price and
at a fixed time in the future, usually not more than seven days from the date of
purchase. 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
 
                                       12
<PAGE>

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. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions, whose
financial condition will be continually monitored by the Investment Manager
subject to procedures established by the Board of Directors of the Fund. In
addition, the value of the collateral underlying the repurchase agreement will
always be at least equal to the repurchase price, including any accrued interest
earned on the repurchase agreement. In the event of a default or bankruptcy by a
selling financial institution, the Fund will seek to liquidate such collateral.
However, the exercising of the Fund's right to liquidate such collateral could
involve certain costs or delays and, to the extent that proceeds from any sale
upon a default of the obligation to repurchase were less than the repurchase
price, the Fund could suffer a loss. It is the current policy of the Fund not to
invest in repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Fund, amounts to
more than 10% of its total assets. The Fund's investments in repurchase
agreements may at times be substantial when, in the view of the Investment
Manager, liquidity or other considerations warrant. During the fiscal year ended
August 31, 1996, the Fund's investments in repurchase agreements did not exceed
5% of its total net assets.
 
    Securities of Foreign Issuers.  The Fund may invest up to 20% of its total
assets in fixed-income securities issued by foreign governments and other
foreign issuers and in foreign currency issues of domestic issuers, but not more
than 10% of its total assets in such securities, whether issued by a foreign or
domestic issuer, which are denominated in foreign currency. The Fund believes
that in many instances such foreign fixed-income securities may provide higher
yields than similar securities of domestic issuers. With the expiration of the
Interest Equalization Tax in 1974, many of these investments currently enjoy
increased liquidity, although such securities are generally less liquid than the
securities of United States corporations, and are certainly less liquid than
securities issued by the United States Government or its agencies.
 

    Foreign investments involve certain risks, including the political or
economic instability of the issuer or of the country of issue, the difficulty of
predicting international trade patterns and the possibility of imposition of
exchange controls. Such securities may also be subject to greater fluctuations
in price than securities of United States corporations or of the United States
Government. In addition, there may be less publicly available information about
a foreign company than about a domestic company. Foreign companies generally are
not subject to uniform accounting, auditing and financial reporting standards
comparable to those applicable to domestic companies. There is generally less
government regulation of stock exchanges, brokers and listed companies abroad
than in the United States, and with respect to certain foreign countries, there
is a possibility of expropriation or confiscatory taxation, or diplomatic
developments which could affect investment in those countries. Finally, in the
event of a default of any such foreign debt obligations, it may be more
difficult for the Fund to obtain or to enforce a judgment against the issuers of
such securities. In addition to the above-mentioned risks, securities
denominated in foreign currency, whether issued by a foreign or a domestic
issuer, may be affected favorably or unfavorably by changes in currency rates
and in exchange control regulations, and costs may be incurred in connection
with conversions between various currencies. It may not be possible to hedge
against the risks of currency fluctuation.

 
    Public Utilities.  As stated in the Prospectus, the Fund's investments in
public utilities, if any, may be subject to certain risks. Such utilities may
have difficulty meeting environmental standards and obtaining satisfactory fuel
supplies at reasonable costs. During an inflationary period, public utilities
also face increasing fuel, construction and other costs and may have difficulty
realizing an adequate return on invested capital. There is no assurance that
regulatory authorities will grant sufficient rate increases to cover expenses
associated with the foregoing difficulties as well as debt service requirements.
In addition, with respect to utilities engaged in nuclear power generation,
there is the possibility that
 
                                       13
<PAGE>

Federal, State or municipal governmental authorities may from time to time
impose additional regulations or take other governmental action which might
cause delays in the licensing, construction, or operation of nuclear power
plants, or suspension of operation of such plants which have been or are being
financed by proceeds of the fixed income securities in the Fund's portfolio.
 

    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. At the time the Fund makes the
commitment to purchase securities on a when-issued, delayed delivery basis or
forward commitment basis with the intention of acquiring the securities, it 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 its custodian bank in which
it will 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 Directors do not believe that the
Fund's net asset value or income will be adversely affected by its purchase of
securities on such basis. The Fund may sell securities on a when-issued or
delayed delivery basis provided that the Fund owns the security at the time of
the sale. During the fiscal year ended August 31, 1996, the Fund did not
purchase any when-issued and delayed delivery securities.

 
    When, as and if Issued Securities.  The Fund may purchase securities on a
"when, as and if issued" basis under which the issuance of the security depends
upon the occurrence of a subsequent event, such as approval of a merger,
corporate reorganization, leveraged buy-out or debt restructuring. 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 maintain cash or U.S. Government Securities or
other liquid portfolio securities equal in value to recognized commitments for
such securities. Once a segregated account has been established, if the
anticipated event does not occur and the securities are not issued the Fund will
have lost an investment opportunity. 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" in the Prospectus). 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 Board of
Directors do not believe that the net asset value of the Fund will be adversely
affected by its purchase of securities on such basis. The Fund may also sell
securities on a "when, as and if issued" basis provided that the issuance of the
security will result automatically from the exchange or conversion of a security
owned by the Fund at the time of the sale. During the fiscal year ended August
31, 1996, the Fund did not purchase securities on a when, as and if issued basis
in an amount which exceeded 5% of its total net assets.
 
    Futures Contracts and Options On Futures.  As discussed in the Prospectus,
the Fund may invest in financial futures contracts ("futures contracts") and
related options thereon. These futures contracts and related options thereon
will be used only as a hedge against anticipated interest rate changes. A
futures contract sale creates an obligation by the Fund, as seller, to deliver
the specific type of instrument called for in the contract at a specified future
time for a specified price. A futures contract purchase would create an
obligation by the Fund, as purchaser, to take delivery of the specific type of
financial instrument
 
                                       14
<PAGE>

at a specified future time at a specified price. The specific securities
delivered or taken, respectively, at settlement date, would not be determined
until or near that date. The determination would be in accordance with the rules
of the exchange on which the futures contract sale or purchase was effected.
 
    The Fund may sell a futures contract or a call option thereon or purchase a
put option on such futures contract, if the Investment Manager anticipates
interest rates to rise, as a hedge against a decrease in the value of the Fund's
portfolio securities. If the Investment Manager anticipates that interest rates
will decline, the Fund may purchase a futures contract or a call option thereon
or sell a put option on such futures contract to protect against an increase in
the price of the securities the Fund intends to purchase. These futures
contracts and related options thereon will be used only as a hedge against
anticipated interest rate changes.
 
    The Fund may not enter into futures contracts or purchase related options
thereon if immediately thereafter the amount committed to margin plus the amount
paid for premiums for unexpired options on futures contracts exceeds 5% of the
value of the Fund's total assets. The Fund may not purchase or sell futures
contracts or related options thereon if, immediately thereafter, more than
one-third of its net assets would be hedged. The Fund did not enter into any
futures transactions during its fiscal year ended August 31, 1996.
 
    Although the terms of futures contracts specify actual delivery or receipt
of securities, in most instances the contracts are closed out before the
settlement date without the making or taking of delivery of the securities.
Closing out of a futures contract is usually effected by entering into an
offsetting transaction. An offsetting transaction for a futures contract sale is
effected by the Fund entering into a futures contract purchase for the same
aggregate amount of the specific type of financial instrument and same delivery
date. If the price in the sale exceeds the price in the offsetting purchase, the
Fund is immediately paid the difference and thus realizes a gain. If the
offsetting purchase price exceeds the sale price, the Fund pays the difference
and realizes a loss. Similarly, the closing out of a futures contract purchase
is effected by the Fund entering into a futures contract sale. If the offsetting
sale price exceeds the purchase price, the Fund realizes a gain, and if the
offsetting sale price is less than the purchase price, the Fund realizes a loss.
 
    Unlike a futures contract, which requires the parties to buy and sell a
security on a set date, an option on a futures contract entitles its holder to
decide on or before a future date whether to enter into such a contract. If the
holder decides not to enter into the contract, the premium paid for the contract
is lost. Since the price of the option is fixed at the point of sale, there are
no daily payments of cash to reflect the change in the value of the underlying
contract, as discussed below for futures contracts. The value of the option does
change and is reflected in the net asset value of the Fund.
 
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects futures contracts and options thereon. The initial
margin requirements vary according to the type of the underlying security. 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.
 
    Currently, 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, Certificates of the Government National Mortgage Association and
Bank Certificates of Deposit. The Fund may invest in interest rate futures
contracts covering these types of financial instruments as well as in new types
of such contracts that become available in the future.
 
                                       15
<PAGE>

    Financial futures contracts are traded in an auction environment on the
floors of several Exchanges -- principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange. Each Exchange
guarantees performance under contract provisions through a clearing corporation,
a nonprofit organization managed by the Exchange membership which is also
responsible for handling daily accounting of deposits or withdrawals of margin.
 
    A risk in employing futures contracts to protect against the price
volatility of portfolio securities is that the prices of securities subject to
futures contracts may correlate imperfectly with the behavior of the cash prices
of the Fund's portfolio securities. The correlation may be distorted by the fact
that the futures market is dominated by short-term traders seeking to profit
from the difference between a contract or security price objective and their
cost of borrowed funds. This would reduce their value for hedging purposes over
a short time period. Such distortions are generally minor and would diminish as
the contract approached maturity.
 
    Another risk is that the Fund's manager could be incorrect in its
expectations as to the direction or extent of various interest rate movements or
the time span within which the movements take place. For example, if the Fund
sold futures contracts for the sale of securities in anticipation of an increase
in interest rates, and then interest rates went down instead, causing bond
prices to rise, the Fund would lose money on the sale.
 
    Put and call options on financial futures have similar characteristics as
Exchange traded options. For a further description of options, see below and
pages 7 and 8 of the Prospectus.
 
    In addition to the risks associated in investing in options on securities,
there are particular risks associated with investing in options on futures. In
particular, the ability to establish and close out positions on such options
will be subject to the development and maintenance of a liquid secondary market.
It is not certain that this market will develop.
 
    A substantial majority (i.e., approximately 75%) of all anticipatory hedge
transactions (transactions in which the Fund does not own at the time of the
transaction, but expects to acquire, the securities underlying the relevant
futures contract) involving the purchase of futures contracts, call options or
written put options thereon will be completed by the purchase of securities
which are the subject of the hedge.
 
    The Fund may not enter into futures contracts or related options thereon if,
immediately thereafter, the amount committed to margin plus the amount paid for
option premiums exceeds 5% of the value of the Fund's total assets. In instances
involving the purchase of futures contracts by the Fund, an amount equal to the
market value of the futures contract will be deposited in a segregated account
of cash and cash equivalents to collateralize the position and thereby ensure
that the use of such futures contract is unleveraged. The Fund may not purchase
or sell futures contracts or related options if, immediately thereafter, more
than one-third of its net assets would be hedged.
 
    Options.  As discussed in the Prospectus, the Fund may purchase or sell
options on debt securities. The Fund would only buy options listed on national
securities exchanges, except for agreements, sometimes called cash puts, which
may accompany the purchase of a new issue of bonds from a dealer.
 
    A call option is a contract that gives the holder of the option the right to
buy from the writer (seller) of the call option, in return for a premium, the
security underlying the option at a specified exercise price at any time during
the term of the option. The writer of the call option has the obligation upon
exercise of the option to deliver the underlying security upon payment of the
exercise price during the option period. A put option is a contract that gives
the holder of the option the right to sell to the writer, in return for a
premium, the underlying security at a specified price during the term of the
option. The writer of the put has the obligation to buy the underlying security
upon exercise, at the exercise price during the option period. The Fund did not
enter into any options transactions during its fiscal year ended August 31,
1995, and it has no intention of doing so during the forseeable future.
 
                                       16
<PAGE>

    The Fund will only write covered call or covered put options. The Fund may
only write covered options which are listed on national securities exchanges.
The Fund may not write covered options in an amount exceeding 20% of the value
of its total assets. A call option is "covered" if the Fund owns the underlying
security covered by the call or has an absolute and immediate right to acquire
that security without additional cash consideration (or for additional cash
consideration held in a segregated account by its custodian) upon conversion or
exchange of other securities held in its portfolio. A call option is also
covered if the Fund holds, on a share-for-share basis, a call on the same
security as the call written where the exercise price of the call held is (i)
equal to or less than the exercise price of the call written or (ii) greater
than the exercise price of the call written if the difference is maintained by
the Fund in cash, Treasury bills or other liquid portfolio securities in a
segregated account with its custodian. A put option is "covered" if the Fund
maintains cash, Treasury bills or other liquid portfolio securities with a value
equal to the exercise price in a segregated account with its custodian, or else
holds, on a share-for-share basis, a put on the same security as the put written
where the exercise price of the put held is equal to or greater than the
exercise price of the put written.
 
    If the Fund has written an option, it may terminate its obligation by
effecting a closing purchase transaction. This is accomplished by purchasing an
option of the same series as the option previously written. However, once the
Fund has been assigned an exercise notice, the Fund will be unable to effect a
closing purchase transaction. Similarly, if the Fund is the holder of an option
it may liquidate its position by effecting a closing sale transaction. This is
accomplished by selling an option of the same series as the option previously
purchased. There can be no assurance that either a closing purchase or sale
transaction can be effected when the Fund so desires. The Fund may only buy
options which are listed on national securities exchanges. The Fund will not
purchase options if, as a result, the aggregate cost of all outstanding options
exceeds 10% of the Fund's total assets.
 
    The Fund will realize a profit from a closing transaction if the price of
the transaction is less than the premium received from writing the option or is
more than the premium paid to purchase the option; the Fund will realize a loss
from a closing transaction if the price of the transaction is more than the
premium received from writing the option or is less than the premium paid to
purchase the option. Since call option prices generally reflect increases in the
price of the underlying security, any loss resulting from the repurchase of a
call option may also be wholly or partially offset by unrealized appreciation of
the underlying security. If a put option written by the Fund is exercised, the
Fund may incur a loss equal to the difference between the exercise price of the
option and the sum of the sale price of the underlying security plus the premium
received from the sale of the option. Other principal factors affecting the
market value of a put or a call option include supply and demand, interest
rates, the current market price and price volatility of the underlying security
and the time remaining until the expiration date.
 
    An option position may be closed out only on an exchange which provides a
secondary market for an option of the same series. Although the Fund will
generally purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular option. In such event, it might not be
possible to effect closing transactions in particular options, so that the Fund
would have to exercise its options in order to realize any profit and would
incur brokerage commissions upon the exercise of call options and upon the
subsequent disposition of underlying securities for the exercise of put options.
If the Fund as a covered call option writer is unable to effect a closing
purchase transaction in a secondary market, it will not be able to sell the
underlying security until the option expires or it delivers the underlying
security upon exercise.
 
    The Fund now qualifies and intends to remain qualified as a "regulated
investment company" under the Internal Revenue Code (see "Dividends,
Distributions and Taxes"). One requirement for such qualification is that less
than 30% of the Fund's gross income must be derived from the gains from the sale
or other disposition of securities held for less than three months. Therefore,
the Fund may be limited in its ability to engage in futures and options
transactions.

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, which 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% of the shares present at a meeting
of shareholders, if the holders of more than 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. Make short sales of securities;
 
        2. Purchase securities on margin, except for such short-term loans as
    are necessary for the clearance of purchases of portfolio securities;
 
        3. Pledge its assets or assign or otherwise encumber them in excess of
    4.5% of its net assets (taken at market value at the time of
    pledging) and then only to secure borrowings effected within the limitations
    set forth in Restriction 14. For the purpose of this restriction, collateral
    arrangements with respect to the writing of options and collateral
    arrangements with respect to initial margin for futures are not deemed to be
    pledges of assets;
 
        4. 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;
 
        5. Purchase or sell real estate or interests therein, although it may
    purchase securities of issuers which engage in real estate operations
    and securities which are secured by real estate or interests therein;
 
        6. Purchase or sell commodities except that the Fund may purchase
    financial futures contracts and related options;
 
        7. Make loans of money or securities, except (a) by the purchase of debt
    obligations in which the Fund may invest consistent with its
    investment objectives and policies; (b) by investment in repurchase
    agreements (see "Portfolio Characteristics -- Repurchase Agreements"); or
    (c) by lending its portfolio securities, subject to limitations described
    elsewhere in this Statement of Additional Information. See "Portfolio
    Characteristics -- Lending of Portfolio Securities";
 
        8. 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 invest in or sponsor
    such programs;
 
        9. Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or
    acquisition of assets;
 
       10. Invest for the purpose of exercising control or management of another
    company;
 
       11. Invest in securities of any company if, to the knowledge of the Fund,
    any officer or director of the Fund or of the Investment Manager owns
    more than 1/2 of 1% of the outstanding securities of such company, and such
    officers and directors who own more than 1/2 of 1% own in the aggregate more
    than 5% of the outstanding securities of such company; and
 
       12. Write, purchase or sell puts, calls, or combinations thereof except
    options on futures contracts or options on debt securities.
 
       13. Borrow money, except that the Fund may borrow for temporary purposes
    in amounts not exceeding 5% (taken at the lower of cost or current
    value) of its total assets (not including the amount borrowed).
 
                                       18
<PAGE>

    As regards the above investment restrictions and those disclosed in the
Prospectus, if a percentage restriction is addressed 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 objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.

 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject to the general supervision by the Board of Directors, the Investment
Manager is responsible for decisions to buy and sell securities and futures
contracts 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. The Fund expects that the primary market
for the securities in which it intends to invest will generally be the
over-the-counter market. Securities are generally traded in the over-the-counter
market on a "net" basis with dealers acting as principal for their own accounts
without charging a stated commission, although the price of the security usually
includes a profit to the dealer. Options and futures transactions will usually
be effected through a broker and a commission will be charged. The Fund also
expects that securities will be purchased at times in underwritten offerings
where the price includes a fixed amount of compensation, generally referred to
as the underwriter's concession or discount. On occasion, the Fund may also
purchase certain money market instruments directly from an issuer, in which case
no commissions or discounts are paid. The Fund paid $95,014, $179,154 and
$301,392 in brokerage commissions during the fiscal years ended August 31, 1994,
1995 and 1996, respectively.
 

    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 and
futures contracts for its portfolio is that primary consideration will be given
to obtaining the most favorable prices and efficient executions of transactions.
In seeking to implement the Fund's policies, the Investment Manager effects
transactions with those brokers and dealers who the Investment Manager believes
provide the most favorable prices and who 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.
 
    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
 
                                       19
<PAGE>

the Investment Manager and thus 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 its transactions with DWR to U.S. Government and Government
Agency Securities, Bank Money Instruments (i.e., Certificates of Deposit and
Bankers' Acceptances) and Commercial Paper (not including Tax-Exempt Municipal
Paper). Such transactions will be effected with DWR only when the price
available from DWR is better than that available from other dealers. During the
fiscal years ended August 31, 1994, 1995 and 1996, the Fund did not effect any
principal transactions with DWR.

 

    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect 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 Directors of the Fund, including a majority of the Directors
who are not "interested" Directors, 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 the
amount of the brokerage commissions it may pay to an affiliated broker or
dealer. During the fiscal years ended August 31, 1994, 1995 and 1996, the Fund
paid no brokerage commissions to any affiliated brokers or dealers.

 

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 agreements
with other selected broker-dealers. The Distributor, a Delaware corporation, is
a wholly-owned subsidiary of MSDWD. The Directors of the Fund, including a
majority of the Directors who are not, and were not at the time they voted,
interested persons of the Fund, as defined in the Act (the "Independent
Directors"), 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 Board.

 

    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

 
                                       20
<PAGE>


the Fund, but in the absence of willful misfeasance, bad faith, gross negligence
or reckless disregard of its obligations, the Distributor is not liable to the
Fund or any of its shareholders for any error of judgment or mistake of law or
for any act or omission or for losses sustained by the Fund or its shareholders.

 

PLAN OF DISTRIBUTION

 

    Effective July 28, 1997, 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 0.85% of the average daily net
assets of Class A and Class C, respectively, and, with respect to Class B, 0.75%
of the average daily net assets of Class B. 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 Distributor has informed the Fund that it and/or DWR received
approximately $2,208,000, $611,000 and $1,594,948 in front-end sales charges for
the fiscal years ended August 31, 1994, 1995 and 1996, respectively.

 

    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 0.20% of the average daily net assets of Class B
and 0.25% of the average daily net assets of Class C 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 Board of Directors, including
all of the Directors of the Fund who are not "interested persons" of the Fund
(as defined in the Act) and who have no direct or indirect financial interest in
the operation of the Plan (the "Independent 12b-1 Directors"), cast in person at
a meeting called for the purpose of voting on the Plan, on June 30, 1997.

 

    Under its terms, the Plan has an initial term ending April 30, 1998 and will
continue from year to year thereafter, provided such continuance is approved
annually by a vote of the Directors in the manner described above.

 

    Under the Plan and as required by Rule 12b-1, the Directors receive and
review promptly after the end of each calendar quarter a written report provided
by the Distributor of the amounts expended under the Plan and the purpose for
which such expenditures were made.

 

    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.

 

    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 4.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.20% 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 Company ("DWTC") or Dean Witter Trust FSB
("DWTFSB") 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 4.0% of the amount sold (except as
provided in the following sentence) and an annual residual commission,

 
                                       21
<PAGE>


currently a residual of up to 0.20% of the current value of the respective
accounts for which they are the account executives of record 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 DWTC or DWTFSB 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 0.85% 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 sales. The distribution fee that
the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred under the Plan 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 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 its
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.

 

    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 0.85%, 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 Directors, including
a majority of the Independent 12b-1 Directors. 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,

 
                                       22
<PAGE>


then in making quarterly determinations of the amounts that may be reimbursed by
the Fund, the Distributor will provide and the Directors 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 Directors 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.

 

    At any given time, the expenses of 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. Because there is no requirement under the
Plan that the Distributor be reimbursed for all distribution 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 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 Directors 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 nor any Director of the Fund who is not an
interested person of the Fund, as defined in the Act, has any direct financial
interest in the operation of the Plan except to the extent that the Distributor,
InterCapital, DWR, DWSC or certain of their employees may be deemed to have such
an interest as a result of benefits derived from the successful operation of the
Plan or as a result of receiving a portion of the amounts expended thereunder by
the Fund.

 

    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval by the shareholders of the
affected Class or Classes of the Fund, and all material amendments to the Plan
must also be approved by the Directors 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 Independent 12b-1 Directors 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 Directors
shall be committed to the discretion of the Independent 12b-1 Directors.

 

DETERMINATION OF NET ASSET VALUE

- --------------------------------------------------------------------------------
 

    As discussed in the Prospectus, 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 currently observes the following holidays: New Year's Day;
President's 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.

 
                                       23
<PAGE>


    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 4.0% 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 Company (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 (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.

 
                                       24
<PAGE>


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, 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:

 



                                                     CDSC AS A PERCENTAGE OF
YEAR SINCE PURCHASE PAYMENT MADE                         AMOUNT REDEEMED
- -------------------------------------------------   --------------------------
                                                                             
First............................................             5.0%

Third............................................             3.0%
Fourth...........................................             2.0%
Fifth............................................             2.0%

    The following table sets forth the rates of the CDSC applicable to Class B
shares of the Fund held by 401(k) plans or other employer-sponsored plans
qualified under Section 401(a) of the Internal Revenue Code for which DWTC or
DWTFSB serves as Trustee or the 401(k) Support Services Group of DWR serves as
recordkeeper and whose accounts are opened on or after July 28, 1997:

 



                                                  CDSC AS A PERCENTAGE OF
YEAR SINCE PURCHASE PAYMENT MADE                      AMOUNT REDEEMED
- -----------------------------------------------  --------------------------
                                                                            
First..........................................               2.0%
Second.........................................               2.0%
Third..........................................               1.0%
Fourth and thereafter..........................             None


 

    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, 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 stock certificate. If a
stock 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 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 other selected
broker-dealer, and will be forwarded to the shareholder, upon the receipt of
proper instructions.

 

    Targeted Dividends.(SM)  In states where it is legally permissible,
shareholders may also have all income dividends and capital gains distributions
automatically invested in shares of any Class of an

 
                                       26
<PAGE>


open-end Dean Witter Fund other than Dean Witter High Yield Securities Inc. or
in another Class of Dean Witter High Yield Securities Inc. 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. 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 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 offering price. The plan provides for monthly or quarterly (March,
June, September and December) checks in any 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.

 

    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").

 
                                       27
<PAGE>


    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 an eligible guarantor). A shareholder may,
at any time, change the amount and interval of withdrawal payments through his
or her account executive or by written notification to the Transfer Agent. In
addition, the party and/or the address to which checks are mailed may be changed
by written notification to the Transfer Agent, with signature guarantees
required in the manner described above. The shareholder may also terminate the
Withdrawal Plan at any time by written notice to the Transfer Agent. In the
event of such termination, the account will be continued as a regular
shareholder investment account. The shareholder may also redeem all or part of
the shares held in the Withdrawal Plan account (see "Redemptions and
Repurchases" in the Prospectus) at any time.

 

    Direct Investments Through Transfer Agent.  As discussed in the Prospectus,
shareholders 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 High Yield Securities Inc., 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. 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

 
                                       28

<PAGE>

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 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 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

 
                                       29

<PAGE>

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 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, at its discretion, accept initial investments of 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 authorities (presently sixty days' prior written notice
for termination or material revision), provided that six months' prior written
notice of termination will be given to the shareholders who hold shares of
Exchange Funds pursuant to this Exchange Privilege, and provided further that
the Exchange Privilege may be terminated or materially revised without notice at
times (a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable
for the Fund fairly to determine the value of its net assets, (d) during any
other period when the Securities and Exchange Commission by order so permits
(provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether the conditions prescribed in (b) or (c)
exist), or (e) if the Fund would be unable to invest amounts effectively in
accordance with its investment objective(s), policies and restrictions.

 
    For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other selected broker-dealer 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

 
                                       30

<PAGE>

their net asset value next computed (see "Purchase of Fund Shares" in the
Prospectus) 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 (including a
certificate or bank cashier's check), payment of redemption proceeds may be
delayed for the minimum time needed to verify that the check used for investment
has been honored (not more than fifteen days from the time of receipt of the
check by the Transfer Agent). Shareholders maintaining margin accounts with DWR
or another selected broker-dealer are referred to their account executive
regarding restrictions on redemption of shares of the Fund pledged in the margin
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 described in the Prospectus, a shareholder who
has had his or her shares redeemed or repurchased and has not previously
exercised this reinstatement privilege may, within 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 such
proceeds, is received by the Transfer Agent.

 
    Exercise of the reinstatement privilege will not affect the federal income
tax treatment of any gain or loss realized upon the redemption or repurchase,
except that if the redemption or repurchase resulted in
 
                                       31

<PAGE>

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.
 
    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 tax-exempt bonds
issued after July 18, 1984, and all bonds purchased after April 30, 1993, a
portion of any capital gain realized upon disposition may be re-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. Dividend income is recorded on the ex-dividend
date.
 

    Gains or losses on the 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. In determining
amounts to be distributed, capital gains will be offset by any capital loss
carryovers incurred in prior years.

 
    Any dividend or capital gains distribution received by a shareholder from an
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 some
portion of the 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 realized long-term capital gains, such payment 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 taxable to the
shareholder. Therefore, an investor should consider the tax implications of
purchasing Fund shares immediately prior to a distribution record date.
 
    Shareholders should consult their attorneys or tax advisers regarding
specific questions as to state or local taxes and as to the applicability of the
foregoing to their current federal tax situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 

    As discussed in the Prospectus, from time to time the Fund may quote its
"yield" and/or its "total return" in advertisements and sales literature. These
figures are computed separately for Class A, Class B, Class C and Class D
shares.

 

    Prior to July 28, 1997, the Fund offered only one Class of shares. Because
the distribution arrangement for Class A most closely resembles the distribution
arrangement applicable prior to the implementation of multiple classes (i.e.,
Class A is sold with a front-end sales charge), historical performance
information has been restated to reflect the actual maximum sales charge
applicable to Class A (i.e., 4.25%) as compared to the 5.5% sales charge in
effect prior to July 28, 1997. In addition, because all shares of the Fund held
prior to July 28, 1997 have been designated Class D shares, the Fund's
historical performance has also been restated to reflect the absence of any
sales charge in the case of Class D shares. In addition, Class A shares are now
subject to an ongoing 12b-1 fee which is not reflected in the restated
performance for that Class and would reduce the performance quoted below.

 
                                       32

<PAGE>

Following the restated performance information is the actual performance of the
Fund as of its last fiscal year (prior to the implementation of multiple
classes) without taking into effect the new fee and sales charge structure.

 

    Yield is calculated for any 30-day period as follows: the amount of interest
and/or dividend income for each security in the Fund's portfolio is determined
in accordance with regulatory requirements; the total for the entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during the
period are subtracted to arrive at "net investment income" of each Class. The
resulting amount is divided by the product of the maximum offering price per
share on the last day of the period multiplied by the average number of shares
of the applicable Class outstanding during the period that were entitled to
dividends. This amount is added to 1 and raised to the sixth power. 1 is then
subtracted from the result and the difference is multiplied by 2 to arrive at
the annualized yield. For the 30-day period ended August 31, 1996, the Fund's
restated yield for the Class A and Class D shares, calculated pursuant to this
formula was 11.88% and 12.43%, respectively.

 

    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 restated average annual total returns of the Class A and Class D
shares of the Fund for the year ended August 31, 1996 were 6.35% and 11.07%,
respectively; for the five years ended August 31, 1996 were 14.77% and 15.77%,
respectively; and for the ten years ended August 31, 1996 were 6.06% and 6.53%,
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 calculation 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 in the manner described in the preceding paragraph, but
without the deduction for any applicable sales charge. Based on the foregoing
calculation, the Fund's total return for Class A shares for the year ended
August 31, 1996 was 11.07%, the total return for the five years ended August 31,
1996 was 15.77% and the total return for the ten years ended August 31, 1996 was
6.53%. Because the Class D shares are not subject to any sales charge, the Fund
would only advertise average annual total returns as calculated in the previous
paragraph.

 

    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 percentage obtained by dividing the ending
value (without reduction for any sales charge) by the initial $1,000 investment
and subtracting 1 from the result. Based on the foregoing calculation, the
Fund's restated total return for both Class A and Class D shares for the year
ended August 31, 1996 was 11.07%; the restated total return for the five years
ended August 31, 1996 was 107.95%; and the restated total return for the ten
years ended August 31, 1996 was 88.16%.

 

    The Fund may 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 $9,575,
$48,250 and $97,250 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,

 
                                       33

<PAGE>

Class C and Class D, as the case may be. Investments of $10,000, $50,000 and
$100,000 in the Fund at inception would have grown to $45,959, $231,595 and
$466,790, respectively, in the case of Class A, and $47,999, $239,995 and
$479,990, respectively, in the case of Class D, at August 31, 1996.

    For the 30-day period ended August 31, 1996, the Fund's actual yield,
calculated pursuant to the formula described above, was 11.73%. The average
annual total returns of the Fund, calculated pursuant to the formula described 
above, for the year ended August 31, 1996, for the five years ended 
August 31, 1996, and for the ten years ended August 31, 1996, were 4.96%, 14.47%
and 5.92%, respectively. The average annual total returns of the Fund calculated
without the deduction for any applicable sales charge for the year ended 
August 31, 1996, for the five years ended August 31, 1996, and for the ten 
years ended August 31, 1996, were 11.07%, 15.77% and 6.53%, respectively. The 
Fund's aggregate total return, calculated pursuant to the formula described 
above, for the year ended August 31, 1996 was 11.07%, the total return for the 
five years ended August 31, 1996 was 107.95% and the total return for the ten 
years ended August 31, 1996 was 88.16%. Investments of $10,000, $50,000 and 
$100,000, adjusted for the sales charges in effect at such time (5.5%, 4.25% 
or 3.25%, respectively), in the Fund at inception would have grown to $45,359, 
$229,795 and $464,390, respectively, at August 31, 1996.

    The Fund from time to time may also advertise its performance relative to
certain performance rankings and indexes compiled by independent organizations.

NOTES TO FINANCIAL STATEMENTS August 31, 1996
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter High Yield Securities Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's primary investment objective is to
earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund was
incorporated in Maryland on June 14, 1979.
 
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 or American 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; (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, portfolio securities are
valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Directors (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 portfolio securities may be valued by an outside pricing service
approved by the Directors. The pricing service utilizes a matrix system
incorporating security quality, maturity and coupon as the evaluation model
parameters, and/or research and evaluations by its staff, including review of
broker-dealer market price quotations, if available, in determining what it
believes is the fair valuation of the portfolio securities valued by such
pricing service; and (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.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.

NOTES TO FINANCIAL STATEMENTS August 31, 1996, continued
 
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 with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a
management fee, calculated daily and payable monthly, by applying the following
annual rates to the net assets of the Fund determined as of the close of each
business day: 0.50% to the portion of daily net assets not exceeding $500
million; 0.425% to the portion of daily net assets exceeding $500 million but
not exceeding $750 million; 0.375% to the portion of daily net assets exceeding
$750 million but not exceeding $1 billion; 0.35% to the portion of daily net
assets exceeding $1 billion but not exceeding $2 billion; 0.325% to the portion
of daily net assets exceeding $2 billion but not exceeding $3 billion; and 0.30%
to the portion of daily net assets exceeding $3 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. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended August 31, 1996, aggregated
$393,514,207 and $415,856,430, respectively.
 
Dean Witter Trust Company, an affiliate of the Investment Manager, is the Fund's
transfer agent. At August 31, 1996, the Fund had transfer agent fees and
expenses payable of approximately $57,000.
 
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Directors of the Fund who will have served as independent
Directors/Trustees for at least five years at the time of retirement. Benefits
under this plan are based on years of service and compensation during the last
five years of service. Aggregate pension costs for the year ended August 31,
1996 included in Directors' fees and expenses in the Statement of Operations
amounted to $1,274. At August 31, 1996, the Fund had an accrued pension
liability of $49,856 which is included in accrued expenses in the Statement of
Assets and Liabilities.
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Distributor has
informed the Fund that for the year ended August 31, 1996, it received
approximately $1,595,000 in commissions from the sale of shares of the Fund's
capital stock. Such commissions are deducted from the proceeds of the capital
stock shares and are not an expense of the Fund.

dividend payable and permanent book/tax differences primarily attributable to an
expired capital loss carryover. To reflect reclassifications arising from
permanent book/tax differences for the year ended August 31, 1996,
paid-in-capital was charged and accumulated net realized loss was credited
$37,795,049.

DEAN WITTER HIGH YIELD SECURITIES INC.
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS
OF DEAN WITTER HIGH YIELD SECURITIES INC.
 
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 High Yield Securities
Inc. (the "Fund") at August 31, 1996, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the ten years in the
period then ended, 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 August
31, 1996 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter High Yield Securities Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's primary investment objective is to
earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund was
incorporated in Maryland on June 14, 1979 and commenced operations on September
26, 1979.
 
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 Directors); (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 Directors
(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 portfolio securities may be valued by an outside
pricing service approved by the Directors. 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.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.
 
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, calculated daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.50% to the portion of daily net assets not exceeding
$500 million; 0.425% to the portion of daily net assets exceeding $500 million
but not exceeding $750 million; 0.375% to the portion of daily net assets
exceeding $750 million but not exceeding $1 billion; 0.35% to the portion of
daily net assets exceeding $1 billion but not exceeding $2 billion; 0.325% to
the portion of daily net assets exceeding $2 billion but not exceeding $3
billion; and 0.30% to the portion of daily net assets exceeding $3 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. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended February 28, 1997, aggregated
$237,747,854 and $220,427,940, respectively.
 
Dean Witter Trust Company, an affiliate of the Investment Manager, is the Fund's
transfer agent. At February 28, 1997, the Fund had transfer agent fees and
expenses payable of approximately $56,000.
 
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Directors of the Fund who will have served as independent
Directors for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the six months ended February 28, 1997
included in Directors' fees and expenses in the Statement of Operations amounted
to $635. At February 28, 1997, the Fund had an accrued pension liability of
$48,911 which is included in accrued expenses in the Statement of Assets and
Liabilities.
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Distributor has
informed the Fund that for the six months ended February 28, 1997, it received
approximately $963,000 in commissions from the sale of shares of the Fund's
capital stock. Such commissions are deducted from the proceeds of the capital
stock shares and are not an expense of the Fund.

Participation   Investors  and   Templeton  Global   Governments  Income  Trust,
closed-end investment companies.
 
    Pursuant to an  Investment Management Agreement  (the "Agreement") with  the
Investment  Manager, the Fund has retained  the Investment Manager to manage the
investment of  the  Fund's assets,  including  the  placing of  orders  for  the
purchase  and sale of  portfolio securities. The  Investment Manager obtains and
evaluates such  information  and  advice relating  to  the  economy,  securities
markets,  and  specific  securities  as  it  considers  necessary  or  useful to
continuously manage  the assets  of the  Fund in  a manner  consistent with  its
investment objective.
 
    Under  the  terms  of the  Agreement,  in  addition to  managing  the Fund's
investments, the Investment Manager  maintains certain of  the Fund's books  and
records  and  furnishes,  at its  own  expense, such  office  space, facilities,
equipment, clerical help and bookkeeping and certain legal services as the  Fund
may reasonably require in the conduct of its business, including the preparation
of  prospectuses,  statements of  additional  information, proxy  statements and
reports required  to be  filed  with federal  and state  securities  commissions
(except  insofar as the  participation or assistance  of independent accountants
and attorneys  is,  in the  opinion  of  the Investment  Manager,  necessary  or
desirable).  In  addition,  the  Investment Manager  pays  the  salaries  of all
personnel, including officers of the Fund,  who are employees of the  Investment
Manager.  The Investment Manager also bears the cost of telephone service, heat,
light, power and other  utilities provided to the  Fund. The Investment  Manager
has retained DWSC to perform its administrative services under the Agreement.
 
    The Fund pays all expenses incurred in its operation. Expenses not expressly
assumed  by the Investment Manager under the  Agreement or by the Distributor of
the  Fund's  shares,  Dean  Witter  Distributors  Inc.  ("Distributors"  or  the
"Distributor")  (see "Purchase of Fund  Shares"), will be paid  by the Fund. The
expenses borne by the Fund include, but are not limited to: charges and expenses
of any  registrar;  custodian, stock  transfer  and dividend  disbursing  agent;
brokerage  commissions;  taxes; engraving  and  printing of  share certificates;
registration costs of the Fund and its shares under federal and state securities
laws; the cost and expense of printing, including typesetting, and  distributing
Prospectuses   and  Statements  of  Additional   Information  of  the  Fund  and
supplements thereto to  the Fund's shareholders;  all expenses of  shareholders'
and  trustees'  meetings  and  of  preparing,  printing  and  mailing  of  proxy
statements and reports to shareholders; fees and travel expenses of trustees  or
members  of  any  advisory board  or  committee  who are  not  employees  of the
Investment Manager or  any corporate  affiliate of the  Investment Manager;  all
expenses incident to any dividend, withdrawal or redemption options; charges and
expenses  of any outside service used for pricing of the Fund's shares; fees and
expenses of  legal  counsel, including  counsel  to  the trustees  who  are  not
interested  persons  of the  Fund or  of the  Investment Manager  (not including
compensation or  expenses  of attorneys  who  are employees  of  the  Investment
Manager)  and independent accountants; membership dues of industry associations;
interest on the Fund's  borrowings; postage; insurance  premiums on property  or
personnel  (including  officers and  trustees) of  the Fund  which inure  to its
benefit; extraordinary expenses including, but not limited to, legal claims  and
liabilities  and  litigation  costs  and  any  indemnification  relating thereto
(depending upon the  nature of the  legal claim, liability  or lawsuit) and  all
other costs of the Fund's operations properly payable by the Fund.
 
    As  full compensation for the services  and facilities furnished to the Fund
and expenses of the Fund  assumed by the Investment  Manager, the Fund pays  the
Investment  Manager monthly compensation calculated daily by applying the annual
rate of 0.50% to the daily net assets of the Fund up to $500 million and  0.425%
to  the Fund's daily net assets over $500 million. Total compensation accrued to
the Investment Manager for the period  June 2, 1994 (commencement of the  Fund's
operations) through March 31, 1995
 
                                       4
<PAGE>
pursuant  to the Agreement amounted to  $350,117. This compensation reflects the
waiver of the investment management fee during a portion of the period. Had  the
fee  not been  waived, compensation  payable to  the Investment  Manager for the
period pursuant to the Agreement would have amounted to $374,452. For the fiscal
years ended  March  31,  1996  and  March  31,  1997,  the  Fund  accrued  total
compensation  to  the  Investment  Manager  in  the  amounts  of  $1,650,429 and
$3,685,133, 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 Investment Manager paid the organizational expenses of the Fund incurred
prior to the offering of the  Fund's shares. The Fund reimbursed the  Investment
Manager  for such expenses. The Fund will defer and will amortize the reimbursed
expenses on the straight line method over a period not to exceed five years from
the date of commencement of the Fund's operations.
 
    The Agreement was initially  approved by the Trustees  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 Trustees  on May  10,
1994  and by  InterCapital as  the then  sole shareholder  on May  10, 1994. The
Agreement may be terminated at any time, without penalty, on thirty days' notice
by the Trustees of  the Fund, by  the holders of a  majority of the  outstanding
shares of the Fund, as defined in the Investment Company Act of 1940, as amended
(the  "Act"), or  by the  Investment Manager.  The Agreement  will automatically
terminate in the event of its assignment (as defined in the Act).
 
    Under its terms, the  Agreement has an initial  term ending April 30,  1999,
and  will continue 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 of the outstanding shares of the Fund, as defined in the Act, or by the
Trustees of the Fund; provided that in either event such continuance is approved
annually  by the  vote of a  majority of  the Trustees of  the Fund  who are not
parties to the Agreement or "interested persons" (as defined in the Act) of  any
such  party (the "Independent Trustees"), which vote must be cast in person at a
meeting called for the purpose of voting on such approval.
 
    The 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
InterCapital  and its parent company is  terminated, the Fund will eliminate the
name "Dean Witter" from its name if DWR or its parent company shall so request.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
 
    The  Board of Trustees consists  of eight (8) trustees;  as noted above, Mr.
Hedien's term will commence  on September 1, 1997.  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 83 Dean Witter Funds, comprised of
126 portfolios. As of May 31, 1997,  the Dean Witter Funds had total net  assets
of approximately $86.4 billion and more than five million shareholders.
 
    Six  Trustees and Mr. Hedlien (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 six independent Trustees are also Independent Trustees of the TCW/DW Funds.
 
    Law and regulation establish both general guidelines and specific duties for
the  Independent Trustees.  The Dean Witter  Funds seek  as Independent Trustees
individuals of distinction  and experience in  business and finance,  government
service  or academia; these are people whose advice and counsel are in demand by
others and for  whom there is  often competition.  To accept a  position on  the
Funds'  Boards, such individuals may reject other attractive assignments because
the Funds make  substantial demands  on their time.  Indeed, by  serving on  the
Funds'  Boards, certain Trustees who would  otherwise be qualified and in demand
to serve on bank boards would be prohibited by law from doing so.
 
    All of  the current  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.
 
                                       8
<PAGE>
    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 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
 
                                       9
<PAGE>
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.
 
CASH COMPENSATION OF INDEPENDENT TRUSTEES
 
    The Fund pays each Independent  Trustee an annual fee  of $1,000 plus a  per
meeting  fee of $50 for  meetings of the Board of  Trustees or committees of the
Board of Trustees attended  by the Trustee  (the Fund pays  the Chairman of  the
Audit  Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent Trustees  an additional  annual fee  of $1,200).  The Fund  also
reimburses such Trustees for travel and other out-of-pocket expenses incurred by
them  in connection with  attending such meetings. Trustees  and officers of the
Fund who are or have  been employed by the  Investment Manager or an  affiliated
company receive no compensation or expense reimbursement from the Fund.
 
    The  following  table  illustrates  the  compensation  paid  to  the  Fund's
Independent Trustees by the Fund for the fiscal year ended March 31, 1997.

    As of the date of this Statement  of Additional Information, 57 of the  Dean
Witter  Funds, not including  the Fund, have adopted  a retirement program under
which an Independent Trustee who retires  after serving for at least five  years
(or  such lesser  period as may  be determined  by the Board)  as an Independent
Director or Trustee  of any  Dean Witter Fund  that has  adopted the  retirement
program (each
 
                                       10
<PAGE>
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 57 Dean Witter Funds (not including the Fund)
for the year ended December 31, 1996, and the estimated retirement benefits  for
the  Fund's Independent Trustees, to commence upon their retirement, 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 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.
 
    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
- --------------------------------------------------------------------------------
 
    REPURCHASE AGREEMENTS.   As discussed in  the Prospectus, when  cash may  be
available  for only  a few days,  it may be  invested by the  Fund in repurchase
agreements until such time as it may otherwise be invested or used for  payments
of  obligations of the Fund. These agreements, which  may be viewed as a type of
secured lending by the  Fund, typically involve the  acquisition by the Fund  of
debt securities from a selling financial institution such as a bank, savings and
loan  association or  broker-dealer. The agreement  provides that  the Fund will
sell back to  the institution,  and that  the institution  will repurchase,  the
underlying  security ("collateral") at a specified price  and at a fixed time in
the future, usually  not more than  seven days  from the date  of purchase.  The
collateral  will be  maintained in  a segregated account  and will  be marked to
market daily to determine that the value of the collateral, as specified in  the
 
                                       11
<PAGE>
agreement,  does not decrease below the purchase price plus accrued interest. If
such  decrease  occurs,  additional  collateral  will  be  requested  and,  when
received, added to the account to maintain full collateralization. The Fund will
accrue  interest from the institution  until the time when  the repurchase is to
occur. Although such date  is deemed by the  Fund to be the  maturity date of  a
repurchase  agreement,  the  maturities  of  securities  subject  to  repurchase
agreements are not subject to any limits.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large,  well-capitalized  and  well-established  financial  institutions   whose
financial  condition  will be  continually monitored  by the  Investment Manager
subject to  procedures established  by the  Board of  Trustees of  the Fund.  In
addition,  as  described  above,  the value  of  the  collateral  underlying the
repurchase agreement will be at least  equal to the repurchase price,  including
any  accrued interest  earned on  the repurchase  agreement. In  the event  of a
default or bankruptcy by a selling financial institution, the Fund will seek  to
liquidate  such  collateral.  However, the  exercising  of the  Fund's  right to
liquidate such collateral  could involve  certain costs  or delays  and, to  the
extent  that  proceeds  from  any  sale upon  a  default  of  the  obligation to
repurchase were less than the repurchase price, the Fund could suffer a loss. It
is the current policy of the Fund not to invest in repurchase agreements that do
not mature within  seven days if  any such investment,  together with any  other
illiquid  assets held by the  Fund, amounts to more than  15% of its net assets.
The Fund's  investments in  repurchase agreements  may at  times be  substantial
when,   in  the  view  of  the  Investment  Manager,  liquidity,  tax  or  other
considerations warrant. For the fiscal year  ended March 31, 1997, the Fund  did
not  enter into any repurchase agreements in an amount exceeding 5% of its total
net assets.
 
    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 four business days'
notice.  If the borrower fails to deliver the loaned securities within four days
after receipt  of notice,  the Fund  could  use the  collateral to  replace  the
securities  while holding the borrower liable for any excess of replacement cost
over collateral. As with any extensions of  credit, there are risks of delay  in
recovery  and in  some cases even  loss of  rights in the  collateral should the
borrower of the securities fail  financially. However, these loans of  portfolio
securities  will only  be made to  firms deemed  by the Fund's  management to be
creditworthy and when the income which  can be earned from such loans  justifies
the  attendant risks. Upon termination of the  loan, the borrower is required to
return the securities to the Fund. Any  gain or loss in the market price  during
the  loan period would inure to the Fund. The creditworthiness of firms to which
the Fund lends its portfolio securities will be monitored on an ongoing basis by
the Investment  Manager  pursuant to  procedures  adopted and  reviewed,  on  an
ongoing basis, by the Board of Trustees of the Fund.
 
    When  voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the  policy of calling the loaned securities,  to
be  delivered within one day after notice, to permit the exercise of such rights
if the matters involved would have a material effect on the Fund's investment in
such loaned securities.  The Fund will  pay reasonable finder's,  administrative
and custodial fees in connection with a loan of its securities.
 
    WHEN-ISSUED  AND DELAYED  DELIVERY SECURITIES  AND FORWARD  COMMITMENTS.  As
discussed in the Prospectus, from time to time the Fund may purchase  securities
on a when-issued or delayed delivery basis or may purchase or sell securities on
a  forward commitment basis. When such transactions are negotiated, the price is
fixed at the time of the commitment,  but delivery and payment can take place  a
 
                                       12
<PAGE>
month  or more after the  date of commitment. While  the Fund will only purchase
securities on a when-issued, delayed  delivery or forward commitment basis  with
the  intention of  acquiring the  securities, the  Fund may  sell the securities
before the  settlement  date, if  it  is  deemed advisable.  The  securities  so
purchased or sold are subject to market fluctuation and no interest or dividends
accrue to the purchaser prior to the settlement date. At the time the Fund makes
the commitment to purchase or sell securities on a when-issued, delayed delivery
or  forward  commitment basis,  it will  record  the transaction  and thereafter
reflect the value,  each day,  of such  security purchased,  or if  a sale,  the
proceeds  to be  received, in determining  its net  asset value. At  the time of
delivery of the securities, the value may  be more or less than the purchase  or
sale price. The Fund will also establish a segregated account with its custodian
bank  in which it  will continually maintain  cash or cash  equivalents or other
liquid portfolio securities equal in value to commitments to purchase securities
on a when-issued, delayed delivery or  forward commitment basis. Subject to  the
foregoing  restrictions, the Fund may purchase  securities on such basis without
limit. During the fiscal year  ended March 31, 1997,  the Fund did not  purchase
any securities on a when-issued and delayed delivery 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  maintain  cash  or  cash
equivalents  or other liquid  portfolio securities equal  in value to recognized
commitments for such securities. Once a segregated account has been established,
if the anticipated event does not occur  and the securities are not issued,  the
Fund  will  have  lost  an  investment  opportunity.  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 Fund may also sell securities on a "when,
as and if issued" basis provided that  the issuance of the security will  result
automatically from the exchange or conversion of a security owned by the Fund at
the  time of the sale. During the fiscal year ended March 31, 1997, the Fund did
not purchase any securities on a when, as and if issued basis in an amount which
exceeded 5% of its total net assets.
 
    PRIVATE PLACEMENTS.  As discussed in the Prospectus, the Fund may invest  up
to  10% of its total  assets in securities which  are subject to restrictions on
resale because they have not been  registered under the Securities Act of  1933,
as   amended  (the  "Securities  Act"),  or  which  are  otherwise  not  readily
marketable. (Securities  eligible  for  resale  pursuant to  Rule  144A  of  the
Securities Act, and determined to be liquid pursuant to the procedures discussed
in  the  following paragraph,  are not  subject  to the  foregoing restriction.)
Limitations on the resale of such securities may have an adverse effect on their
marketability, and  may prevent  the Fund  from disposing  of them  promptly  at
reasonable  prices. The Fund  may have to  bear the expense  of registering such
securities for  resale and  the risk  of substantial  delays in  effecting  such
registration.
 
    The  Securities and Exchange Commission ("SEC")  has adopted Rule 144A under
the Securities Act,  which permits  the Fund  to sell  restricted securities  to
qualified  institutional  buyers  without  limitation.  The  Investment Manager,
pursuant to  procedures  adopted  by the  Trustees  of  the Fund,  will  make  a
determination  as to the liquidity of  each restricted security purchased by the
Fund. The procedures require that the following factors be taken into account in
making a liquidity determination: (1) the  frequency of trades and price  quotes
for  the security; (2) the number of  dealers and other potential purchasers who
have issued quotes on the security; (3) any dealer undertakings to make a market
in the
 
                                       13
<PAGE>
security; and (4) the nature of the  security and the nature of the  marketplace
trades  (the time needed  to dispose of  the security, the  method of soliciting
offers, and the mechanics of transfer).  If a restricted security is  determined
to be "liquid", such security will not be included within the category "illiquid
securities",  which under the SEC's  current policies may not  exceed 15% of the
Fund's net assets, and will not be subject to the 10% limitation set out in  the
preceding paragraph.
 
    The  Rule 144A marketplace of sellers  and qualified institutional buyers is
new and still developing and may take a period of time to develop into a  mature
liquid  market. As  such, the  market for  certain private  placements purchased
pursuant to Rule  144A may be  initially small or  may, subsequent to  purchase,
become  illiquid. Furthermore,  the Investment  Manager may  not posses  all the
information concerning an issue  of securities that it  wishes to purchase in  a
private  placement  to  which  it  would  normally  have  had  access,  had  the
registration statement necessitated  by a  public offering been  filed with  the
Securities and Exchange Commission.
 
    REVERSE  REPURCHASE  AGREEMENTS  AND  DOLLAR ROLLS.    As  discussed  in the
Prospectus, the Fund may also use reverse repurchase agreements and dollar rolls
as part of its investment strategy. Reverse repurchase agreements involve  sales
by  the Fund of portfolio  assets concurrently with an  agreement by the Fund to
repurchase the same  assets at a  later date  at a fixed  price. Generally,  the
effect  of such a  transaction is that the  Fund can recover all  or most of the
cash invested  in the  portfolio  securities involved  during  the term  of  the
reverse  repurchase agreement, while it will be able to keep the interest income
associated  with  those  portfolio   securities.  Such  transactions  are   only
advantageous  if  the  interest  cost  to the  Fund  of  the  reverse repurchase
transaction is less than the cost of obtaining the cash otherwise.
 
    The Fund may enter into dollar rolls in which the Fund sells securities  for
delivery  in  the  current  months and  simultaneously  contracts  to repurchase
substantially similar (same type  and coupon) securities  on a specified  future
date.  During the roll period,  the Fund forgoes principal  and interest paid on
the securities. The Fund  is compensated by the  difference between the  current
sales  price and the lower forward price for the future purchase (often referred
to as the "drop") as well as by the interest earned on the cash proceeds of  the
initial sale.
 
    The  Fund will  establish a  segregated account  with its  custodian bank in
which it  will  maintain  cash,  U.S.  Government  Securities  or  other  liquid
portfolio  securities equal  in value to  its obligations in  respect of reverse
repurchase agreements and dollar rolls. Reverse repurchase agreements and dollar
rolls involve the  risk that  the market  value of  the securities  the Fund  is
obligated  to repurchase  under the agreement  may decline  below the repurchase
price. In the event the buyer of securities under a reverse repurchase agreement
or dollar roll  files for  bankruptcy or becomes  insolvent, the  Fund's use  of
proceeds of the agreement may be restricted pending a determination by the other
party,  or its trustee or receiver, whether  to enforce the Fund's obligation to
repurchase the securities.  Reverse repurchase agreements  and dollar rolls  are
speculative  techniques involving leverage, and are considered borrowings by the
Fund.
 
    ZERO COUPON SECURITIES.   As discussed in the  Prospectus, a portion of  the
U.S.  Government Securities purchased by the  Fund may be "zero coupon" Treasury
securities. These  are U.S.  Treasury bills,  notes and  bonds which  have  been
stripped  of  their  unmatured  interest  coupons  and  receipts  or  which  are
certificates representing  interests  in  such  stripped  debt  obligations  and
coupons. In addition, a portion of the fixed-income securities purchased by such
Fund  may be "zero coupon" securities. "Zero coupon" securities are purchased at
a discount from  their face amount,  giving the purchaser  the right to  receive
their  full value at  maturity. A zero  coupon security pays  no interest to its
holder during at least a portion of its life. Its value to an investor  consists
of  the difference between its face value at  the time of maturity and the price
for which it was acquired, which is generally an amount significantly less  than
its face value (sometimes referred to as a "deep discount" price).
 
    The  interest  earned  on  such  securities  is,  implicitly,  automatically
compounded and paid out at maturity.  While such compounding at a constant  rate
eliminates  the risk of receiving lower  yields upon reinvestment of interest if
prevailing interest rates decline, the owner  of a zero coupon security will  be
 
                                       14
<PAGE>
unable to participate in higher yields upon reinvestment of interest received if
prevailing  interest rates  rise. For  this reason,  zero coupon  securities are
subject to substantially  greater market  price fluctuations  during periods  of
changing  prevailing interest  rates than  are comparable  debt securities which
make current distributions of interest. Current federal tax law requires that  a
holder  (such as  the Fund) of  a zero coupon  security accrue a  portion of the
discount at which the security was purchased as income each year even though the
Fund receives no interest payments in cash on the securities during the year.
 
    Currently, the only  U.S. Treasury  security issued without  coupons is  the
Treasury  bill. However, in the  last few years a  number of banks and brokerage
firms have  separated  ("stripped")  the  principal  portions  from  the  coupon
portions  of the U.S. Treasury  bonds and notes and  sold them separately in the
form of  receipts  or certificates  representing  undivided interests  in  these
instruments  (which instruments are generally  held by a bank  in a custodial or
trust account).
 

    RIGHTS AND WARRANTS.   As  stated in the  Prospectus, the  Fund may  acquire
rights  and warrants which are attached to other securities in its portfolio, or
which are issued  as a  distribution by  the issuer of  a security  held in  its
portfolio. Warrants are, in effect, an option to purchase equity securities at a
specific  price, generally  valid for  a specific  period of  time, and  have no
voting rights,  pay  no  dividends  and  have no  rights  with  respect  to  the
corporation  issuing them. The  Fund does not  anticipate acquiring any warrants
during its fiscal year ending March 31, 1997.

 
    CONVERTIBLE SECURITIES.    As  stated  in the  Prospectus,  certain  of  the
fixed-income  securities purchased  by the Fund  may be  convertible into common
stock of the issuer.  Convertible securities rank senior  to common stocks in  a
corporation's  capital  structure  and,  therefore, entail  less  risk  than the
corporation's common stock. The value of a convertible security is a function of
its "investment value" (its value as if it did not have a conversion privilege),
and its "conversion value" (the security's worth if it were to be exchanged  for
the underlying security, at market value, pursuant to its conversion privilege).
 
    To the extent that a convertible security's investment value is greater than
its  conversion  value,  its  price  will  be  primarily  a  reflection  of such
investment value and its  price will be likely  to increase when interest  rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit  standing of the issuer and other factors  may also have an effect on the
convertible security's value).  If the conversion  value exceeds the  investment
value,  the price  of the  convertible security  will rise  above its investment
value and, in  addition, will sell  at some premium  over its conversion  value.
(This  premium  represents  the  price  investors are  willing  to  pay  for the
privilege of purchasing a  fixed-income security with  a possibility of  capital
appreciation  due to the conversion  privilege.) At such times  the price of the
convertible security  will tend  to fluctuate  directly with  the price  of  the
underlying  equity security. Convertible securities may be purchased by the Fund
at varying price levels above their investments values and/ or their  conversion
values in keeping with the Fund's objective.
 
    FOREIGN  SECURITIES.    As  stated  in  the  Prospectus,  foreign securities
investments may be  affected by changes  in currency rates  or exchange  control
regulations,  changes  in governmental  administration  or economic  or monetary
policy (in the United  States and abroad) or  changed circumstances in  dealings
between  nations. Fluctuations  in the  relative rates  of exchange  between the
currencies of different nations will affect the value of the Fund's  investments
denominated  in  foreign currency.  Changes in  foreign currency  exchange rates
relative to the  U.S. dollar will  affect the  U.S. dollar value  of the  Fund's
assets  denominated in  that currency and  thereby impact upon  the Fund's total
return on such assets.
 
    Foreign currency  exchange rates  are  determined by  forces of  supply  and
demand  on the foreign exchange markets. These forces are themselves affected by
the  international  balance  of  payments  and  other  economic  and   financial
conditions,  government intervention,  speculation and  other factors. Moreover,
foreign currency exchange rates may be affected by the regulatory control of the
exchanges on which the  currencies trade. The  foreign currency transactions  of
the  Fund will  be conducted  on a  spot basis  or through  forward contracts or
futures contracts (described  in the Statement  of Additional Information).  The
Fund will incur certain costs in connection with these currency transactions.
 
                                       15
<PAGE>
    Investments  in  foreign securities  will  also occasion  risks  relating to
political  and  economic  developments  abroad,  including  the  possibility  of
expropriations  or confiscatory taxation, limitations on  the use or transfer of
Fund  assets  and  any  effects   of  foreign  social,  economic  or   political
instability. Foreign companies are not subject to the regulatory requirements of
U.S.  companies and, as  such, there may be  less publicly available information
about such companies. Moreover,  foreign companies are not  subject to the  more
rigorous  uniform  accounting, auditing  and  financial reporting  standards and
requirements applicable to U.S. companies.
 
    Securities of foreign issuers may be less liquid than comparable  securities
of  U.S.  issuers  and, as  such,  their  price changes  may  be  more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to  less
government   and   exchange  scrutiny   and   regulation  than   their  American
counterparts. Brokerage commissions,  dealer concessions  and other  transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements  of Fund  trades effected in  such markets. Inability  to dispose of
portfolio securities due to settlement delays could result in losses to the Fund
due to subsequent declines in value of such securities and the inability of  the
Fund to make intended security purchases due to settlement problems could result
in  a failure of the  Fund to make potentially  advantageous investments. To the
extent the Fund purchases Eurodollar  certificates of deposit issued by  foreign
branches  of domestic United States banks,  consideration will be given to their
domestic marketability,  the lower  reserve requirements  normally mandated  for
overseas banking operations, the possible impact of interruptions in the flow of
international  currency  transactions,  and future  international  political and
economic developments which might adversely  affect the payment of principal  or
interest.
 
    FORWARD  FOREIGN CURRENCY EXCHANGE CONTRACTS.   As stated in the Prospectus,
the Fund may enter  into forward foreign  currency exchange contracts  ("forward
contracts")  as a hedge  against fluctuations in  future foreign exchange rates.
The Fund will  conduct its foreign  currency exchange transactions  either on  a
spot  (i.e., cash)  basis at  the spot rate  prevailing in  the foreign currency
exchange market, or through entering into forward contracts to purchase or  sell
foreign  currencies. A  forward contract involves  an obligation  to purchase or
sell a specific currency at a future date, which may be any fixed number of days
from the date of the contract agreed upon by the parties, at a price set at  the
time  of  the  contract. These  contracts  are  traded in  the  interbank market
conducted directly  between  currency  traders (usually  large,  commercial  and
investment  banks)  and their  customers. Such  forward  contracts will  only be
entered into with  United States  banks and  their foreign  branches or  foreign
banks,  insurance companies and  other dealers whose assets  total $1 billion or
more.  A  forward  contract  generally  has  no  deposit  requirement,  and   no
commissions are charged at any stage for trades.
 
    When  management  of the  Fund believes  that the  currency of  a particular
foreign country may suffer  a substantial movement against  the U.S. dollar,  it
may  enter into a  forward contract to purchase  or sell, for  a fixed amount of
dollars or  other currency,  the amount  of foreign  currency approximating  the
value  of some  or all  of the Fund's  portfolio securities  denominated in such
foreign currency.
 
    The Fund will enter into forward contracts under various circumstances. When
the Fund  enters  into  a contract  for  the  purchase or  sale  of  a  security
denominated  in a foreign currency, it may, for example, desire to "lock in" the
price of the security in U.S. dollars  or some other foreign currency which  the
Fund  is  temporarily  holding in  its  portfolio.  By entering  into  a forward
contract for  the purchase  or sale,  for a  fixed amount  of dollars  or  other
currency,  of the amount of foreign currency involved in the underlying security
transactions, the Fund will  be able to protect  itself against a possible  loss
resulting  from an adverse change in the relationship between the U.S. dollar or
other currency which is being used for the security purchase (by the Fund or the
counterparty) and  the foreign  currency in  which the  security is  denominated
during  the period between the  date on which the  security is purchased or sold
and the date on which payment is made or received.
 
    At other times, when,  for example, the  Fund's Investment Manager  believes
that  the  currency of  a particular  foreign country  may suffer  a substantial
decline against the  U.S. dollar or  some other foreign  currency, the Fund  may
enter  into a forward contract  to sell, for a fixed  amount of dollars or other
 
                                       16
<PAGE>
currency, the amount of foreign currency approximating the value of some or  all
of  the Fund's securities  holdings (or securities which  the Fund has purchased
for its  portfolio)  denominated  in  such  foreign  currency.  Under  identical
circumstances,  the Fund may enter into a  forward contract to sell, for a fixed
amount of U.S. dollars  or other currency, an  amount of foreign currency  other
than  the  currency  in  which  the  securities  to  be  hedged  are denominated
approximating the value of some or all of the portfolio securities to be hedged.
This method  of  hedging,  called  "cross-hedging,"  will  be  selected  by  the
Investment  Manager when it is determined that the foreign currency in which the
portfolio securities are denominated has insufficient liquidity or is trading at
a discount as compared with some other  foreign currency with which it tends  to
move in tandem.
 
    In  addition,  when  the Fund's  Investment  Manager  anticipates purchasing
securities at  some time  in  the future,  and wishes  to  lock in  the  current
exchange  rate of the currency in which those securities are denominated against
the U.S.  dollar or  some other  foreign currency,  the Fund  may enter  into  a
forward  contract to purchase an amount of currency  equal to some or all of the
value of the anticipated purchase, for a  fixed amount of U.S. dollars or  other
currency.  The  Fund  may,  however,  close  out  the  forward  contract without
purchasing the security which was the subject of the "anticipatory" hedge.
 
    The Fund will not enter into forward contracts or maintain a net exposure to
such contracts where the consummation of  the contracts would obligate the  Fund
to  deliver an amount of  foreign currency in excess of  the value of the Fund's
portfolio securities or other assets denominated in that currency. Under  normal
circumstances,  consideration  of the  prospect  for currency  parities  will be
incorporated into  the longer  term  investment decisions  made with  regard  to
overall diversification strategies. However, the management of the Fund believes
that  it  is  important to  have  the  flexibility to  enter  into  such forward
contracts when it determines that the best interests of the Fund will be served.
The Fund's custodian bank will place  cash, U.S. Government securities or  other
appropriate  liquid portfolio securities in a  segregated account of the Fund in
an amount  equal to  the  value of  the Fund's  total  assets committed  to  the
consummation of forward contracts entered into under the circumstances set forth
above. If the value of the securities placed in the segregated account declines,
additional  cash or securities will be placed in the account on a daily basis so
that the value of the  account will equal the  amount of the Fund's  commitments
with respect to such contracts.
 
    Where,  for example, the Fund is  hedging a portfolio position consisting of
foreign securities denominated  in a foreign  currency against adverse  exchange
rate  moves vis-a-vis the U.S.  dollar, at the maturity  of the forward contract
for delivery by the  Fund of a  foreign currency, the Fund  may either sell  the
portfolio  security and make delivery of the  foreign currency, or it may retain
the security and  terminate its  contractual obligation to  deliver the  foreign
currency  by purchasing an  "offsetting" contract with  the same currency trader
obligating it to purchase,  on the same  maturity date, the  same amount of  the
foreign  currency (however, the ability  of the Fund to  terminate a contract is
contingent upon the willingness  of the currency trader  with whom the  contract
has  been entered into to permit an offsetting transaction). It is impossible to
forecast the  market value  of portfolio  securities at  the expiration  of  the
contract.  Accordingly, it may be necessary  for the Fund to purchase additional
foreign currency on the spot market (and  bear the expense of such purchase)  if
the market value of the security is less than the amount of foreign currency the
Fund  is obligated to deliver and if a decision is made to sell the security and
make delivery of the foreign currency.  Conversely, it may be necessary to  sell
on  the spot market some  of the foreign currency received  upon the sale of the
portfolio securities if its market value exceeds the amount of foreign  currency
the Fund is obligated to deliver.
 
    If  the Fund retains  the portfolio securities and  engages in an offsetting
transaction, the Fund will  incur a gain  or loss to the  extent that there  has
been  movement in  spot or forward  contract prices.  If the Fund  engages in an
offsetting transaction, it may subsequently enter into a new forward contract to
sell the  foreign currency.  Should  forward prices  decline during  the  period
between  the Fund's entering into  a forward contract for  the sale of a foreign
currency and the date it enters into an offsetting contract for the purchase  of
the  foreign currency, the Fund  will realize a gain to  the extent the price of
the currency it has
 
                                       17
<PAGE>
agreed to sell  exceeds the price  of the  currency it has  agreed to  purchase.
Should  forward prices increase, the  Fund will suffer a  loss to the extent the
price of  the currency  it  has agreed  to purchase  exceeds  the price  of  the
currency it has agreed to sell.
 
    If  the Fund purchases a fixed-income  security which is denominated in U.S.
dollars but which will pay  out its principal based upon  a formula tied to  the
exchange  rate between  the U.S.  dollar and  a foreign  currency, it  may hedge
against a decline  in the principal  value of  the security by  entering into  a
forward  contract to sell  an amount of  the relevant foreign  currency equal to
some or all of the principal value of the security.
 
    At times  when the  Fund has  written a  call option  on a  security or  the
currency  in  which it  is  denominated, it  may wish  to  enter into  a forward
contract to  purchase or  sell the  foreign currency  in which  the security  is
denominated.  A  forward contract  would,  for example,  hedge  the risk  of the
security on which a call option has been written declining in value to a greater
extent than the  value of the  premium received  for the option.  The Fund  will
maintain  with its Custodian at all  times, cash, U.S. Government securities, or
other liquid portfolio securities in a segregated account equal in value to  all
forward  contract obligations  and option  contract obligations  entered into in
hedge situations such as this.
 
    Although the Fund values its assets daily in terms of U.S. dollars, it  does
not  intend to convert its holdings of foreign currencies into U.S. dollars on a
daily basis. It will, however, do so from time to time, and investors should  be
aware  of the costs of currency conversion. Although foreign exchange dealers do
not charge a fee for  conversion, they do realize a  profit based on the  spread
between the prices at which they are buying and selling various currencies. Thus
a  dealer may offer  to sell a foreign  currency to the Fund  at one rate, while
offering a  lesser  rate of  exchange  should the  Fund  desire to  resell  that
currency to the dealer.
 
    In  all  of the  above  circumstances, if  the  currency in  which  the Fund
securities holdings (or anticipated portfolio securities) are denominated  rises
in  value with respect to the currency  which is being purchased (or sold), then
the Fund will have realized fewer gains  than had the Fund not entered into  the
forward  contracts.  Moreover,  the  precise matching  of  the  forward contract
amounts and the value of the securities involved will not generally be possible,
since the future value of such securities in foreign currencies will change as a
consequence of market  movements in the  value of those  securities between  the
date  the forward contract is entered into and  the date it matures. The Fund is
not required  to  enter  into  such transactions  with  regard  to  its  foreign
currency-denominated  securities and will not do so unless deemed appropriate by
the Investment  Manager.  The Fund  generally  will  not enter  into  a  forward
contract  with  a term  of greater  than one  year, although  it may  enter into
forward contracts for periods of  up to five years. The  Fund may be limited  in
its  ability to enter  into hedging transactions  involving forward contracts by
the Internal Revenue Code (the  "Code") requirements relating to  qualifications
as a regulated investment company (see "Dividends, Distributions and Taxes").
 
OPTIONS AND FUTURES TRANSACTIONS
 
    As stated in the Prospectus, the Fund may write covered call options against
securities  held in its portfolio and  covered put options on eligible portfolio
securities and stock indexes and purchase  options of the same series to  effect
closing  transactions, and  may hedge  against potential  changes in  the market
value  of   investments  (or   anticipated  investments)   and  facilitate   the
reallocation  of the  Fund's assets  into and  out of  equities and fixed-income
securities by  purchasing  put  and  call  options  on  portfolio  (or  eligible
portfolio)  securities and engaging in  transactions involving futures contracts
and options on such contracts. The Fund may also hedge against potential changes
in the market value of the  currencies in which its investments (or  anticipated
investments)  are denominated by  purchasing put and  call options on currencies
and engage in transactions involving  currency futures contracts and options  on
such contracts.
 
    Call  and put  options on  U.S. Treasury notes,  bonds and  bills and equity
securities  are  listed  on  Exchanges  and  are  written  in   over-the-counter
transactions ("OTC options"). Listed options are issued
 
                                       18
<PAGE>
by  the  Options  Clearing  Corporation  ("OCC")  and  other  clearing  entities
including foreign exchanges. Ownership  of a listed call  option gives the  Fund
the  right to buy from the OCC the  underlying security covered by the option at
the stated exercise  price (the price  per unit of  the underlying security)  by
filing an exercise notice prior to the expiration date of the option. The writer
(seller)  of the option  would then have the  obligation to sell  to the OCC the
underlying security at that exercise price  prior to the expiration date of  the
option,  regardless of its then current market  price. Ownership of a listed put
option would give the Fund the right to sell the underlying security to the  OCC
at  the stated exercise  price. Upon notice  of exercise of  the put option, the
writer of the put would have the obligation to purchase the underlying  security
from the OCC at the exercise price.
 
    OPTIONS  ON TREASURY BONDS AND NOTES.  Because trading in options written on
Treasury bonds and notes tends to center on the most recently auctioned  issues,
the  exchanges on which such securities  trade will not continue indefinitely to
introduce options with new expirations to replace expiring options on particular
issues. Instead,  the  expirations introduced  at  the commencement  of  options
trading  on a  particular issue will  be allowed  to run their  course, with the
possible addition of a  limited number of new  expirations as the original  ones
expire.  Options trading on each issue of bonds or notes will thus be phased out
as new options are listed on more recent issues, and options representing a full
range of expirations will not ordinarily  be available for every issue on  which
options are traded.
 
    OPTIONS ON TREASURY BILLS.  Because a deliverable Treasury bill changes from
week to week, writers of Treasury bill calls cannot provide in advance for their
potential   exercise  settlement  obligations  by   acquiring  and  holding  the
underlying security. However,  if the  Fund holds  a long  position in  Treasury
bills with a principal amount of the securities deliverable upon exercise of the
option,  the position may be  hedged from a risk standpoint  by the writing of a
call option. For so long as the  call option is outstanding, the Fund will  hold
the Treasury bills in a segregated account with its Custodian, so that they will
be treated as being covered.
 
    OPTIONS  ON FOREIGN CURRENCIES.  The Fund  may purchase and write options on
foreign currencies  for purposes  similar to  those involved  with investing  in
forward  foreign currency exchange  contracts. For example,  in order to protect
against  declines  in  the  dollar  value  of  portfolio  securities  which  are
denominated  in a  foreign currency,  the Fund  may purchase  put options  on an
amount of such foreign currency equivalent to the current value of the portfolio
securities involved. As a result, the Fund would be enabled to sell the  foreign
currency  for a fixed  amount of U.S.  dollars, thereby "locking  in" the dollar
value of the portfolio securities (less the amount of the premiums paid for  the
options).  Conversely, the Fund may purchase  call options on foreign currencies
in which securities it  anticipates purchasing are denominated  to secure a  set
U.S. dollar price for such securities and protect against a decline in the value
of  the U.S. dollar  against such foreign  currency. The Fund  may also purchase
call and put options to close out written option positions.
 
    The Fund may also write call options on foreign currency to protect  against
potential  declines in its portfolio securities which are denominated in foreign
currencies. If the  U.S. dollar  value of the  portfolio securities  falls as  a
result of a decline in the exchange rate between the foreign currency in which a
security  is denominated and the U.S. dollar, then a loss to the Fund occasioned
by such value  decline would be  ameliorated by  receipt of the  premium on  the
option  sold. At the  same time, however, the  Fund gives up  the benefit of any
rise in value of the relevant  portfolio securities above the exercise price  of
the  option and, in fact, only receives a benefit from the writing of the option
to the extent that the value of  the portfolio securities falls below the  price
of  the premium received. The Fund may also write options to close out long call
option positions.
 
    The markets in foreign  currency options are relatively  new and the  Fund's
ability  to establish and close out positions  on such options is subject to the
maintenance of a liquid secondary market. Although the Fund will not purchase or
write such options unless  and until, in  the opinion of  the management of  the
Fund, the market for them has developed sufficiently to ensure that the risks in
connection with such
 
                                       19
<PAGE>
options  are  not  greater than  the  risks  in connection  with  the underlying
currency, there can be  no assurance that a  liquid secondary market will  exist
for  a particular option at  any specific time. In  addition, options on foreign
currencies are affected by all of those factors which influence foreign exchange
rates and investments generally.
 
    The value  of  a foreign  currency  option depends  upon  the value  of  the
underlying  currency relative to the U.S. dollar.  As a result, the price of the
option position may vary with changes in the value of either or both  currencies
and  have  no  relationship to  the  investment  merits of  a  foreign security,
including foreign securities  held in a  "hedged" investment portfolio.  Because
foreign   currency  transactions  occurring  in  the  interbank  market  involve
substantially larger  amounts than  those that  may be  involved in  the use  of
foreign currency options, investors may be disadvantaged by having to deal in an
odd  lot market (generally  consisting of transactions of  less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.
 
    There is  no  systematic reporting  of  last sale  information  for  foreign
currencies  or  any  regulatory requirement  that  quotations  available through
dealers or other market sources be firm or revised on a timely basis.  Quotation
information  available is generally representative of very large transactions in
the interbank market and  thus may not  reflect relatively smaller  transactions
(i.e.,  less than $1 million)  where rates may be  less favorable. The interbank
market in foreign currencies is a global, around-the-clock market. To the extent
that the U.S. options  markets are closed while  the markets for the  underlying
currencies  remain open, significant price and  rate movements may take place in
the underlying markets that are not reflected in the options market.
 
    OTC OPTIONS.  Exchange-listed  options are issued by  the OCC which  assures
that  all transactions  in such options  are properly executed.  OTC options are
purchased from or sold (written) to dealers or financial institutions which have
entered into direct agreements with the  Fund. With OTC options, such  variables
as  expiration date, exercise price and premium  will be agreed upon between the
Fund and the  transacting dealer, without  the intermediation of  a third  party
such as the OCC. If the transacting dealer fails to make or take delivery of the
securities  underlying an option it has written, in accordance with the terms of
that option, the Fund would lose the premium paid for the option as well as  any
anticipated  benefit  of the  transaction. The  Fund will  engage in  OTC option
transactions only with primary U.S. Government securities dealers recognized  by
the Federal Reserve Bank of New York.
 
    COVERED  CALL WRITING.  The Fund is  permitted to write covered call options
on portfolio  securities and  the U.S.  dollar and  foreign currencies,  without
limit.  Generally, a call option is "covered" if the Fund owns, or has the right
to acquire,  without  additional  cash consideration  (or  for  additional  cash
consideration  held for the Fund  by its Custodian in  a segregated account) the
underlying security (currency) subject to the option except that in the case  of
call options on U.S. Treasury Bills, the Fund might own U.S. Treasury Bills of a
different  series from  those underlying the  call option, but  with a principal
amount and value  corresponding to  the exercise price  and a  maturity date  no
later  than that of the securities (currency) deliverable under the call option.
A call option  is also covered  if the Fund  holds a call  on the same  security
(currency)  as the underlying  security (currency) of  the written option, where
the exercise price of the  call used for coverage is  equal to or less than  the
exercise  price of the  call written or  greater than the  exercise price of the
call written if the mark to market difference is maintained by the Fund in cash,
U.S. Government securities or other  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 (currency) alone. Moreover,  the
income  received from the  premium will offset  a portion of  the potential loss
incurred by the  Fund if  the securities  (currency) underlying  the option  are
ultimately  sold (exchanged) by  the Fund at  a loss. The  premium received will
fluctuate with varying economic  market conditions. If the  market value of  the
portfolio
 
                                       20
<PAGE>
securities  (or the  currencies in which  they are denominated)  upon which call
options have been written increases, the Fund may receive less total return from
the portion of its portfolio  upon which calls have  been written than it  would
have had such calls not been written.
 
    As regards listed options and certain OTC options, during the option period,
the  Fund  may be  required, at  any  time, to  deliver the  underlying security
(currency) against payment  of the exercise  price on any  calls it has  written
(exercise  of  certain  listed  and  OTC  options  may  be  limited  to specific
expiration dates).  This obligation  is terminated  upon the  expiration of  the
option period or at such earlier time when the writer effects a closing purchase
transaction.  A closing  purchase transaction  is accomplished  by purchasing an
option of the same  series as the option  previously written. However, once  the
Fund  has been assigned an exercise notice, the  Fund will be unable to effect a
closing purchase transaction.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an outstanding call  option to  prevent an underlying  security (currency)  from
being  called, to permit the sale of  an underlying security (or the exchange of
the underlying currency) or to enable the  Fund to write another call option  on
the  underlying security  (currency) with either  a different  exercise price or
expiration date or  both. Also,  effecting a closing  purchase transaction  will
permit  the cash or proceeds from the  concurrent sale of any securities subject
to the option to be used for other investments by the Fund. The Fund may realize
a net gain or  loss from a closing  purchase transaction depending upon  whether
the  amount of the premium received on the  call option is more or less than the
cost of  effecting the  closing purchase  transaction. Any  loss incurred  in  a
closing  purchase transaction  may be wholly  or partially  offset by unrealized
appreciation  in  the  market  value  of  the  underlying  security  (currency).
Conversely, a gain resulting from a closing purchase transaction could be offset
in  whole  or in  part or  exceeded  by a  decline in  the  market value  of the
underlying security (currency).
 
    If a call option expires unexercised, the Fund realizes a gain in the amount
of the premium on the option less the commission paid. Such a gain, however, may
be offset  by  depreciation in  the  market  value of  the  underlying  security
(currency)  during the option  period. If a  call option is  exercised, the Fund
realizes a gain  or loss  from the sale  of the  underlying security  (currency)
equal  to the difference  between the purchase price  of the underlying security
(currency) and the  proceeds of  the sale of  the security  (currency) plus  the
premium received for on the option less the commission paid.
 
    Options  written by a Fund normally have expiration dates of from up to nine
months (equity securities) to eighteen months (fixed-income securities) from the
date written. The  exercise price of  a call option  may be below,  equal to  or
above the current market value of the underlying security (currency) at the time
the option is written. See "Risks of Options and Futures Transactions," below.
 
    COVERED  PUT WRITING.  As a writer of  a covered put option, the Fund incurs
an obligation to buy  the security underlying the  option from the 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,  at  all  times,  the Fund  maintains,  in  a  segregated  account
maintained  on  its  behalf  at  the  Fund's  Custodian,  cash,  U.S. Government
securities or other high grade  obligations in an amount  equal to at least  the
exercise  price of the option, at all times during the option period. Similarly,
a short put  position could  be covered by  the Fund  by its purchase  of a  put
option  on the same security  as the underlying security  of the written option,
where the exercise price of  the purchased option is equal  to or more than  the
exercise  price of the  put written or less  than the exercise  price of the put
written if the mark to market difference is maintained by the Fund in cash, U.S.
Government securities or other liquid portfolio securities which the Fund  holds
in  a segregated account maintained at its  Custodian. In writing puts, the Fund
assumes the risk  of loss  should the market  value of  the underlying  security
decline  below the exercise price of the option (any loss being decreased by the
receipt of the premium on  the option written). In  the case of listed  options,
during the option period, the Fund may be required, at any time, to make payment
of the exercise price against delivery of the underlying security. The operation
of  and limitations on  covered put options in  other respects are substantially
identical to those of call options.
 
                                       21
<PAGE>
    The Fund will write put options for two purposes: (1) to receive the  income
derived  from  the premiums  paid  by purchasers;  and  (2) when  the Investment
Manager wishes to purchase the security  underlying the option at a price  lower
than its current market price, in which case it will write the covered put at an
exercise price reflecting the lower purchase price sought. The potential gain on
a  covered put option is limited to the premium received on the option (less the
commissions paid  on  the  transaction)  while the  potential  loss  equals  the
difference between the exercise price of the option and the current market price
of  the underlying securities when  the put is exercised,  offset by the premium
received (less the commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC  call
and  put options in amounts equalling up to 5% of its total assets. The Fund may
purchase call  options  in order  to  close out  a  covered call  position  (see
"Covered Call Writing" above) or purchase call options on securities they intend
to  purchase. The Fund  may also purchase  a call option  on foreign currency to
hedge against  an  adverse exchange  rate  move of  the  currency in  which  the
security  it  anticipates purchasing  is denominated  vis-a-vis the  currency in
which the exercise  price is  denominated. The purchase  of the  call option  to
effect  a closing transaction or a call written over-the-counter may be a listed
or an OTC option. In either case, the call purchased is likely to be on the same
securities (currencies)  and have  the  same terms  as  the written  option.  If
purchased  over-the-counter,  the option  would generally  be acquired  from the
dealer or financial institution which purchased the call written by the Fund.
 
    The Fund may purchase  put options on securities  (currency) which it  holds
(or  has the right to acquire) in its portfolio only to protect itself against a
decline in the value of the security (currency). If the value of the  underlying
security  (currency) were to fall below the  exercise price of the put purchased
in an amount greater than the premium paid for the option, the Fund would  incur
no  additional loss. The Fund may also purchase put options to close out written
put positions in a manner similar to call options closing purchase transactions.
In addition, the Fund may  sell a put option  which it has previously  purchased
prior  to the sale of  the securities (currency) underlying  such option. Such a
sale would result in a net gain or loss depending on whether the amount received
on the sale is more or less than the premium and other transaction costs paid on
the put option which is sold. Any such gain or loss could be offset in whole  or
in  part by a change in the  market value of the underlying security (currency).
If a put option purchased by the  Fund expired without being sold or  exercised,
the premium would be lost.
 
    RISKS  OF OPTIONS TRANSACTIONS.  During  the option period, the covered call
writer has, in return for  the premium on the  option, given up the  opportunity
for capital appreciation above the exercise price should the market price of the
underlying  security (or the currency in  which it is denominated) increase, but
has retained  the risk  of loss  should  the price  of the  underlying  security
(currency)  decline. The covered put writer also retains the risk of loss should
the market  value  of  the  underlying security  (currency)  decline  below  the
exercise  price  of the  option less  the premium  received on  the sale  of the
option. In both cases, the  writer has no control over  the time when it may  be
required  to fulfill its  obligation as a  writer of the  option. Once an option
writer has received  an exercise  notice, it  cannot effect  a closing  purchase
transaction  in  order to  terminate its  obligation under  the option  and must
deliver or receive the underlying securities (currency) at the exercise price.
 
    Prior to exercise or expiration, an  option position can only be  terminated
by  entering into  a closing  purchase or  sale transaction.  If a  covered call
option writer is unable to effect a closing purchase transaction or to  purchase
an  offsetting over-the-counter option,  it cannot sell  the underlying security
until the option expires or the option is exercised. Accordingly, a covered call
option writer  may  not  be  able to  sell  (exchange)  an  underlying  security
(currency) at a time when it might otherwise be advantageous to do so. A covered
put  option writer who is unable to  effect a closing purchase transaction or to
purchase an offsetting over-the-counter option  would continue to bear the  risk
of  decline in the market price of  the underlying security (currency) until the
option expires or is exercised. In addition, a coveredput writer would be unable
to utilize the amount held in cash or U.S. Government or other liquid  portfolio
securities  as security for  the put option for  other investment purposes until
the exercise or expiration of the option.
 
                                       22

    The Fund's ability to  close out its  position as a writer  of an option  is
dependent  upon the existence of a  liquid secondary market on option Exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC options, as such options will generally only be closed out by entering  into
a closing purchase transaction with the purchasing dealer. However, the Fund may
be  able to purchase an offsetting option  which does not close out its position
as a writer but constitutes an asset of equal value to the obligation under  the
option  written. If the Fund is not able to either enter into a closing purchase
transaction or purchase an offsetting position, it will be required to  maintain
the  securities subject to the call, or  the collateral underlying the put, even
though it might not be advantageous to do so, until a closing transaction can be
entered into (or the option is exercised or expires).
 
    Among the possible reasons for the  absence of a liquid secondary market  on
an  Exchange are:  (i) insufficient  trading interest  in certain  options; (ii)
restrictions on  transactions  imposed  by an  Exchange;  (iii)  trading  halts,
suspensions  or other restrictions imposed with respect to particular classes or
series of  options or  underlying securities;  (iv) interruption  of the  normal
operations  on an Exchange; (v)  inadequacy of the facilities  of an Exchange or
the Options Clearing Corporation  ("OCC") to handle  current trading volume;  or
(vi)  a decision by one or more  Exchanges to discontinue the trading of options
(or a  particular class  or series  of options),  in which  event the  secondary
market  on that Exchange (or in that class  or series of options) would cease to
exist, although outstanding options on that Exchange that had been issued by the
OCC as  a result  of trades  on that  Exchange would  generally continue  to  be
exercisable in accordance with their terms.
 
    Exchanges limit the amount by which the price of a 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 options, futures or options  thereon, the Fund could experience
delays and/or losses in liquidating open positions purchased or sold through the
broker and/or  incur a  loss of  all or  part of  its margin  deposits with  the
broker. Similarly, in the event of the bankruptcy of the writer of an OTC option
purchased  by the Fund, the Fund  could experience a loss of  all or part of the
value of the option. Transactions are entered into by the Fund only with brokers
or financial institutions deemed creditworthy by the Investment Manager.
 
    Each of  the Exchanges  has established  limitations governing  the  maximum
number  of  call or  put  options on  the  same underlying  security  or futures
contract (whether or  not covered) which  may be written  by a single  investor,
whether  acting  alone or  in concert  with others  (regardless of  whether such
options are written on the same or different Exchanges or are held or written on
one or more accounts or through one or more brokers). An Exchange may order  the
liquidation  of positions found  to be in  violation of these  limits and it may
impose other sanctions or restrictions.  These position limits may restrict  the
number of listed options which the Fund may write.
 
    While the futures contracts and options transactions to be engaged in by the
Fund  for  the  purpose  of  hedging the  Fund's  portfolio  securities  are not
speculative in nature, there are risks inherent in the use of such  instruments.
One  such risk which may arise in employing futures contracts to protect against
the price volatility of  portfolio securities is that  the prices of  securities
and  indexes  subject to  futures contracts  (and  thereby the  futures contract
prices) may correlate imperfectly  with the behavior of  the cash prices of  the
Fund's  portfolio securities. Another such risk  is that prices of interest rate
futures contracts may not move in tandem with the changes in prevailing interest
rates against which the Fund
 
                                       23
<PAGE>
seeks a hedge. A correlation may also be distorted by the fact that the  futures
market  is dominated by short-term traders seeking to profit from the difference
between a contract or security price objective and their cost of borrowed funds.
Such distortions  are  generally  minor  and  would  diminish  as  the  contract
approached maturity.
 
    The  hours of trading for options may  not conform to the hours during which
the underlying securities  are traded.  To the  extent that  the option  markets
close  before the markets  for the underlying  securities, significant price and
rate movements can take place in the underlying markets that cannot be reflected
in the option markets.
 
    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 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." Options  on 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 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, 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, call  writers such as  the Fund cannot  provide in advance  for
their  potential settlement obligations by  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
 
                                       24
<PAGE>
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.  The Fund may  purchase and sell interest rate and  stock
index  futures  contracts  ("futures contracts")  that  are traded  on  U.S. and
foreign commodity  exchanges  on such  underlying  securities as  U.S.  Treasury
bonds, notes and bills ("interest rate" futures), on the U.S. dollar and foreign
currencies,  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)  securities against  changes in  prevailing interest
rates. If the Investment Manager anticipates  that interest rates may rise  and,
concomitantly,  the price of fixed-income securities  fall, the Fund may sell an
interest rate futures contract  or a bond index  futures contract. If  declining
interest  rates are anticipated, the Fund  may purchase an interest rate futures
contract to protect against a potential increase in the price of U.S. Government
securities the Fund intends to purchase. Subsequently, appropriate  fixed-income
securities may be purchased by the Fund in an orderly fashion; as securities are
purchased,  corresponding futures  positions would  be terminated  by offsetting
sales of contracts.
 
    The Fund will purchase or sell futures  contracts on the U.S. dollar and  on
foreign  currencies to hedge against an anticipated rise or decline in the value
of the U.S. dollar or foreign currency in which a portfolio security of the Fund
is denominated vis-a-vis another currency.
 
    The Fund will purchase or sell stock index futures contracts for the purpose
of hedging its  equity portfolio (or  anticipated portfolio) securities  against
changes in their prices. If the Investment Manager
 
                                       25
<PAGE>
anticipates  that the prices  of stock held by  the Fund may  fall, the Fund may
sell a  stock index  futures  contract. Conversely,  if the  Investment  Manager
wishes  to hedge against anticipated price rises  in those stocks which the Fund
intends to purchase,  the Fund may  purchase stock index  futures contracts.  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.  Index  futures
contracts  provide for the  delivery of an  amount of cash  equal to a specified
dollar amount times the difference between the stock index value at the open  or
close  of the last trading day of the contract and the futures contract price. A
futures contract sale is closed out by effecting a futures contract purchase for
the same aggregate amount of the specific  type of equity security and the  same
delivery  date. If  the sale  price exceeds  the offsetting  purchase price, the
seller would be paid the difference and would realize a gain. If the  offsetting
purchase  price exceeds the sale price, the  seller would pay the difference and
would realize a loss.  Similarly, a futures contract  purchase is closed out  by
effecting  a futures contract sale for the same aggregate amount of the specific
type of equity security and the same delivery date. If the offsetting sale price
exceeds the purchase price, the purchaser  would realize a gain, whereas if  the
purchase  price exceeds the offsetting sale price, the purchaser would realize a
loss. There is no assurance that the Fund  will be able to enter into a  closing
transaction.
 
    INTEREST RATE FUTURES CONTRACTS.  When the Fund enters into an interest rate
futures contract, it is initially required to deposit with the Fund's Custodian,
in a segregated account in the name of the broker performing the transaction, an
"initial margin" of cash or U.S. Government securities or other 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 brokers' client but is, rather,  a good faith deposit on the futures
contract which will be returned to the  Fund upon the proper termination of  the
futures  contract. The margin deposits  made are marked to  market daily and the
Fund may be required to make subsequent deposits called "variation margin", with
the Fund's  Custodian, in  the account  in the  name of  the broker,  which  are
reflective  of price fluctuations  in the futures  contract. Currently, interest
rates futures  contracts  can be  purchased  on  debt securities  such  as  U.S.
Treasury  Bills and Bonds, U.S. Treasury Notes with maturities between 6 1/2 and
10 years, GNMA Certificates and Bank Certificates of Deposit.
 
    INDEX FUTURES CONTRACTS.  The Fund may invest in index futures contracts. An
index futures contract  sale creates an  obligation by the  Fund, as seller,  to
deliver  cash at  a specified  future time.  An index  futures contract purchase
would create an obligation by the Fund,  as purchaser, to take delivery of  cash
at  a specified  future time.  Futures contracts on  indexes do  not require the
physical delivery of securities, but provide for a final cash settlement on  the
expiration  date  which  reflects  accumulated profits  and  losses  credited or
debited to each party's account.
 
    The Fund  is  required to  maintain  margin deposits  with  brokerage  firms
through  which it effects  index futures contracts  in a manner  similar to that
described above  for interest  rate futures  contracts. Currently,  the  initial
margin requirement is approximately 5% of the contract amount for index futures.
In  addition, due  to current industry  practice, daily variations  in gains and
losses on open contracts  are required to  be reflected in cash  in the form  of
variation  margin payments. The  Fund may be required  to make additional margin
payments during the term of the contract.
 
    At any time prior to expiration of the futures contract, the Fund may  elect
to  close the  position by  taking an  opposite position  which will  operate to
terminate the Fund's position in the futures contract. A final determination  of
variation  margin is  then made, additional  cash is  required to be  paid by or
released to the Fund and the Fund realizes a loss or a gain.
 
                                       26
<PAGE>
    Currently, index futures contracts can be purchased or sold with respect to,
among others, the Standard  & Poor's 500  Stock Price Index  and the Standard  &
Poor's  100 Stock Price Index  on the Chicago Mercantile  Exchange, the New York
Stock Exchange  Composite Index  on the  New York  Futures Exchange,  the  Major
Market  Index  on  the  American Stock  Exchange,  the  Moody's Investment-Grade
Corporate Bond Index  on the Chicago  Board of  Trade and the  Value Line  Stock
Index on the Kansas City Board of Trade.
 
    OPTIONS  ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts and enter into closing transactions with respect to
such options to terminate an existing position. An option on a futures  contract
gives  the purchaser the right (in return  for the premium paid), and the writer
the obligation, to assume a position in  a futures contract (a long position  if
the option is a call and a short position if the option is a put) at a specified
exercise  price at any time during the term  of the option. Upon exercise of the
option, the delivery of the futures position by the writer of the option to  the
holder  of the option is  accompanied by delivery of  the accumulated balance in
the writer's futures margin  account, which represents the  amount by which  the
market  price of the  futures contract at  the time of  exercise exceeds, in the
case of a call, or is less than, in the case of a put, the exercise price of the
option on the futures contract.
 
    The Fund will purchase and write options on futures contracts for  identical
purposes  to  those set  forth  above for  the  purchase of  a  futures contract
(purchase of a call option or  sale of a put option)  and the sale of a  futures
contract  (purchase of a put option or sale of a call option), or to close out a
long or short  position in futures  contracts. If, for  example, the  Investment
Manager  wished  to  protect  against  an increase  in  interest  rates  and the
resulting negative  impact  on  the  value of  a  portion  of  its  fixed-income
portfolio,  it might write a  call option on an  interest rate futures contract,
the underlying security of  which correlates with the  portion of the  portfolio
the  Investment Manager seeks to hedge. Any  premiums received in the writing of
options on futures  contracts may, of  course, augment the  total return of  the
Fund  and thereby  provide a further  hedge against losses  resulting from price
declines in portions of the Fund's portfolio.
 
    The writer of an option on a futures contract is required to deposit initial
and variation margin  pursuant to  requirements similar to  those applicable  to
futures  contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.
 
    LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS  ON FUTURES.  The Fund may  not
enter into futures contracts or purchase related options thereon if, immediately
thereafter, the amount committed to margin plus the amount paid for premiums for
unexpired  options on futures  contracts exceeds 5%  of the value  of the Fund's
total assets, after taking into  account unrealized gains and unrealized  losses
on such contracts it has entered into, provided, however, that in the case of an
option that is in-the-money (the exercise price of the call (put) option is less
(more)  than  the  market price  of  the  underlying security)  at  the  time of
purchase, the  in-the-money  amount  may  be excluded  in  calculating  the  5%.
However,  there is no overall limitation on  the percentage of the Fund's assets
which may be subject to  a hedge position. In  addition, in accordance with  the
regulations of the Commodity Futures Trading Commission ("CFTC") under which the
Fund  is exempted from registration  as a commodity pool  operator, the Fund may
only enter into futures contracts and options on futures contracts  transactions
for  purposes of hedging a part or all of its portfolio. If the CFTC changes its
regulations so that  the Fund  would be permitted  to write  options on  futures
contracts  for purposes other  than hedging the  Fund's investments without CFTC
registration, the  Fund may  engage  in such  transactions for  those  purposes.
Except  as described above, there are no other limitations on the use of futures
and options thereon by the Fund.
 
    RISKS OF TRANSACTIONS IN  FUTURES CONTRACTS AND RELATED  OPTIONS.  The  Fund
may  sell a  futures contract  to protect  against the  decline in  the value of
securities held by the Fund. However, it is possible that the futures market may
advance and  the value  of 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
 
                                       27
<PAGE>
decline  in value of  its portfolio securities. However,  while this could occur
for a very brief  period or to  a very small  degree, over time  the value of  a
diversified  portfolio will tend  to move in  the same direction  as the futures
contracts.
 
    If the Fund purchases  a futures contract to  hedge against the increase  in
value  of  securities  it intends  to  buy,  and the  value  of  such securities
decreases, then  the Fund  may determine  not  to invest  in the  securities  as
planned  and will realize a loss on the futures contract that is not offset by a
reduction in the price of the securities.
 
    In addition, if the Fund holds a long position in a futures contract or  has
sold  a put  option on a  futures contract,  it will hold  cash, U.S. Government
securities or other 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.
 
    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 liquid portfolio securities equal  in value (when added to any  initial
or variation margin on deposit) to the market value of the securities underlying
the  futures contract or the  exercise price of the  option. Such a position may
also be covered by owning the securities underlying the futures contract (in the
case of a stock index futures  contract a portfolio of securities  substantially
replicating the relevant index), or by holding a call option permitting the Fund
to  purchase the same contract at a price  no higher than the price at which the
short position was established.
 
    Exchanges may limit the amount by  which the price of futures contracts  may
move  on any day. If  the price moves equal the  daily limit on successive days,
then it may  prove impossible to  liquidate a futures  position until the  daily
limit moves have ceased.
 
    The  extent to which the Fund  may enter into transactions involving options
and futures contracts may be limited by the 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 and
the Statement of Additional Information.
 
    There may  exist an  imperfect correlation  between the  price movements  of
futures  contracts purchased by the Fund and  the movements in the prices of the
securities which are the  subject of the hedge.  If participants in the  futures
market elect to close out their contracts through offsetting transactions rather
than  meet margin deposit  requirements, distortions in  the normal relationship
between the debt securities and futures markets could result. Price  distortions
could also result if investors in futures contracts opt to make or take delivery
of  underlying securities rather than engage  in closing transactions due to the
resultant reduction in the liquidity of the futures market. In addition, due  to
the  fact that, from the point of  view of speculators, the deposit requirements
in the futures  markets are less  onerous than margin  requirements in the  cash
market, increased participation by speculators in the futures market could cause
temporary  price distortions. Due to the possibility of price distortions in the
futures market and because of the imperfect correlation between movements in the
prices of securities and movements in the prices of futures contracts, a correct
forecast of interest rate trends by the Investment Manager may still not  result
in a successful hedging transaction.
 
    There  is no assurance that a liquid secondary market will exist for futures
contracts and related  options in  which the  Fund may  invest. In  the event  a
liquid  market does  not exist, it  may not be  possible to close  out a futures
position, and in the event of  adverse price movements, the Fund would  continue
to  be required to  make daily cash  payments of variation  margin. In addition,
limitations imposed by an exchange or board of trade on which futures  contracts
are  traded may compel or prevent the Fund from closing out a contract which may
result in reduced gain or  increased loss to the Fund.  The absence of a  liquid
market in futures contracts might cause the Fund to make or take delivery of the
underlying securities at a time when it may be disadvantageous to do so.

    Compared  to the purchase or sale of futures contracts, the purchase of call
or put options  on futures contracts  involves less potential  risk to the  Fund
because  the maximum amount  at risk is  the premium paid  for the options (plus
transaction costs). However, there may be  circumstances when the purchase of  a
call  or put option  on a futures  contract would result  in a loss  to the Fund
notwithstanding that the purchase or sale of a futures contract would not result
in a loss, as in the  instance where there is no  movement in the prices of  the
futures contract or underlying securities.
 
    The  Investment  Manager  has  substantial  experience  in  the  use  of the
investment techniques described  above under  the heading  "Options and  Futures
Transactions,"  which techniques require  skills different from  those needed to
select  the  portfolio  securities   underlying  various  options  and   futures
contracts.
 
PORTFOLIO TURNOVER
 
    It  is anticipated that  the Fund's portfolio turnover  rate will not exceed
200%. A 200% turnover rate would occur,  for example, if 200% of the  securities
held  in  the Fund's  portfolio (excluding  all  securities whose  maturities at
acquisition were  one year  or less)  were sold  and replaced  within one  year.
During  the fiscal  years ended March  31, 1996  and March 31,  1997, the Fund's
portfolio turnover rates were 69% and 42%, respectively.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment  restrictions  listed  below  have  been  adopted  by  the  Fund   as
fundamental   policies,  except  as  otherwise   indicated.  Under  the  Act,  a
fundamental policy may  not be changed  without the  vote of a  majority of  the
outstanding  voting  securities of  the  Fund, as  defined  in the  Act.  Such a
majority is defined as the lesser of (a) 67% or more of the shares present at  a
meeting  of shareholders, if the holders of 50% of the outstanding shares of the
Fund are present or represented by proxy or (b) more than 50% of the outstanding
shares of the Fund.
 
    The Fund may not:
 
         1. Purchase or sell real estate or interests therein, although the Fund
    may purchase securities of  issuers which engage  in real estate  operations
    and securities secured by real estate or interests therein.
 
         2.  Purchase  oil,  gas  or other  mineral  leases,  rights  or royalty
    contracts or exploration or development  programs, except that the Fund  may
    invest  in the securities of companies  which operate, invest in, or sponsor
    such programs.
 
         3. Borrow  money, except  that the  Fund  may borrow  from a  bank  for
    temporary  or emergency purposes  in amounts not exceeding  5% (taken at the
    lower of  cost or  current value)  of its  total assets  (not including  the
    amount borrowed).
 
         4.  Pledge its  assets or assign  or otherwise encumber  them except to
    secure borrowings effected within the  limitations set forth in  restriction
    (3).  For  the purpose  of  this restriction,  collateral  arrangements with
    respect to the writing of  options and collateral arrangements with  respect
    to  initial or variation margin for futures  are not deemed to be pledges of
    assets.
 
         5. Issue senior securities as defined in the Act, except insofar as the
    Fund may  be deemed  to  have issued  a senior  security  by reason  of  (a)
    entering into any repurchase or reverse repurchase agreement; (b) purchasing
    any securities on a when-issued or delayed delivery basis; (c) purchasing or
    selling  futures contracts,  forward foreign exchange  contracts or options;
    (d) borrowing money in accordance with restrictions described above; or  (e)
    lending portfolio securities.
 
                                       29
<PAGE>
         6.  Make loans of money  or securities, except: (a)  by the purchase of
    publicly  distributed  debt  obligations  in  which  the  Fund  may   invest
    consistent  with its investment objective and policies; (b) by investment in
    repurchase agreements; or (c) by lending its portfolio securities.
 
         7. Make short sales of securities.
 
         8. Purchase securities on margin,  except for such short-term loans  as
    are  necessary for  the clearance  of portfolio  securities. The  deposit or
    payment by  the Fund  of  initial or  variation  margin in  connection  with
    futures  contracts or related options thereon is not considered the purchase
    of a security on margin.
 
         9. Engage in the underwriting of securities, except insofar as the Fund
    may be deemed an underwriter under  the Securities Act of 1933 in  disposing
    of a portfolio security.
 
        10.  Invest for the  purpose of exercising control  or management of any
    other issuer.
 
        11.  Purchase  securities  of  other  investment  companies,  except  in
    connection  with a  merger, consolidation, reorganization  or acquisition of
    assets or in accordance with the provisions of Section 12(d) of the Act  and
    any Rules promulgated thereunder.
 
        12.  Purchase or sell  commodities or commodities  contracts except that
    the Fund may purchase or sell futures contracts or options on futures.
 
    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 as the Fund.
 
    If a percentage restriction is adhered to at the time of investment, a later
increase  or  decrease  in  percentage  resulting from  a  change  in  values of
portfolio securities or amount of total or  net assets will not be considered  a
violation of any of the foregoing restrictions.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
    Subject  to the general supervision of  the 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.  The Fund expects that the primary  market for the securities in which
it intends  to invest  will generally  be the  over-the-counter market.  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. For the fiscal period June 2, 1994 through March 31, 1995 and for  the
fiscal  years ended March 31, 1996 and March  31, 1997, the Fund paid a total of
$19,845, $71,918 and $46,074, 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
 
                                       30
<PAGE>
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,  and in  most cases  an exact  dollar
value for those services is not ascertainable.
 
    The  Fund  anticipates that  certain of  its transactions  involving foreign
securities will be effected on  foreign securities exchanges. Fixed  commissions
on  such  transactions  are  generally  higher  than  negotiated  commissions on
domestic transactions. There is also  generally less government supervision  and
regulation  of  foreign  securities exchanges  and  brokers than  in  the United
States.
 
    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.
 
    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. For the fiscal year ended March 31, 1997, the Fund did not direct
the payment of any brokerage commissions to brokers because of research services
provided.
 
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR.  The
Fund  will limit  its transactions  with DWR  to U.S.  Government and Government
Agency Securities, Bank  Money Instruments  (i.e., Certificates  of Deposit  and
Bankers'  Acceptances) and Commercial Paper.  Such transactions will be effected
with DWR only when the  price available from DWR  is better than that  available
from  other dealers. During the  fiscal year ended March  31, 1997, the Fund did
not effect any principal transactions with DWR.
 
    Consistent with  the  policy  described  above,  brokerage  transactions  in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected  through DWR. In order for DWR to effect any portfolio transactions for
the Fund, the commissions,  fees or other remuneration  received by DWR must  be
reasonable and fair compared to the commissions, fees or other remuneration paid
to  other brokers in  connection with comparable  transactions involving similar
securities being purchased or sold on an exchange during a comparable period  of
time.  This standard would  allow DWR to  receive no more  than the remuneration
which would  be  expected  to  be  received  by  an  unaffiliated  broker  in  a
 
                                       31
<PAGE>
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 DWR
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 DWR.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    As  discussed in the Prospectus, shares of  the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"). The Distributor has entered into a
dealer agreement with DWR, which through its own sales organization sells shares
of the Fund. In addition, the  Distributor may enter into agreements with  other
selected  dealers  ("Selected  Broker-Dealers").  The  Distributor,  a  Delaware
corporation, is an indirect  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 April 24, 1997, the
current Distribution  Agreement (the  "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 Board.  The
current Distribution Agreement took effect on May 31, 1997 upon the consummation
of  the merger of Dean Witter, Discover & Co. with Morgan Stanley Group Inc. and
is substantially identical to the Fund's previous distribution agreement  except
for its dates of effectiveness and termination.
 
    The  Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor also pays certain  expenses in connection  with the distribution  of
the  Fund's shares, including the costs  of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto  used in connection  with the offering  and
sale  of the  Fund's shares.  The Fund bears  the costs  of initial typesetting,
printing  and   distribution  of   prospectuses  and   supplements  thereto   to
shareholders.  The Fund  also bears  the costs of  registering the  Fund and its
shares under federal  and state securities  laws. The Fund  and the  Distributor
have  agreed  to indemnify  each  other against  certain  liabilities, including
liabilities under the Securities Act of 1933, as amended. Under the Distribution
Agreement, the Distributor uses  its best efforts in  rendering services to  the
Fund,  but in the absence of willful misfeasance, bad faith, gross negligence or
reckless disregard of its obligations, the Distributor is not liable to the Fund
or any of its shareholders  for any error of judgment  or mistake of law or  for
any act or omission or for any losses sustained by the Fund or its shareholders.
 
PLAN OF DISTRIBUTION
 
    To  compensate the  Distributor for the  services it or  any selected dealer
provides and for  the expenses it  bears under the  Distribution Agreement,  the
Fund  has adopted a  Plan of Distribution  pursuant to Rule  12b-1 under the Act
(the "Plan")  pursuant  to which  the  Fund pays  the  Distributor  compensation
accrued  daily and payable monthly at the annual rate of 0.80% of the lesser of:
(a) the  average daily  aggregate gross  sales of  the Fund's  shares since  the
inception of the Fund (not including reinvestments of dividends or capital gains
distributions),  less the average daily aggregate  net asset value of the Fund's
shares redeemed  since the  Fund's inception  upon which  a contingent  deferred
sales  charge has been imposed or upon which such charge has been waived; or (b)
the Fund's average daily  net assets. The Distributor  receives the proceeds  of
contingent  deferred  sales charges  imposed on  certain redemptions  of shares,
which are  separate and  apart from  payments  made pursuant  to the  Plan  (see
"Redemptions  and  Repurchases  --  Contingent  Deferred  Sales  Charge"  in the
Prospectus).  The  Distributor   has  informed   the  Fund   that  it   received
approximately $160,000, $655,000 and $1,408,132,
 
                                       32
<PAGE>
respectively  in contingent deferred  sales charges for the  period June 2, 1994
through March 31, 1995 and for the  fiscal years ended March 31, 1996 and  March
31, 1997, none of which was retained by the Distributor.
 
    The  Distributor has informed the Fund that an amount of the fees payable by
the Fund each year pursuant  to the Plan of Distribution  equal to 0.20% of  the
Fund's  average daily net assets  is characterized as a  "service fee" under the
Rules of Fair Practice of the  National Association of Securities Dealers,  Inc.
(of  which the Distributor is a member). Such fee is a payment made for personal
service and/or the maintenance of shareholder accounts. The remaining portion of
the Plan of Distribution fee  payments made by the  Fund is characterized as  an
"asset-based  sales charge"  as such is  defined by the  aforementioned Rules of
Fair Practice. At their meeting held on  October 26, 1995, the Directors of  the
Fund, including all of the independent 12b-1 Directors, approved an amendment to
the  Plan to permit payments  to be made under the  Plan with respect to certain
distribution expenses incurred  in connection with  the distribution of  shares,
including  personal services  to shareholders with  respect to  holdings of such
shares, of an  investment company whose  assets are  acquired by the  Fund in  a
tax-free reorganization.
 
    The  Plan was adopted by a vote of the Trustees of the Fund on May 10, 1994,
at a meeting of the Trustees called for the purpose of voting on such Plan.  The
vote  included the vote  of a majority of  the Trustees of the  Fund who are not
"interested persons" of the Fund (as defined in the Act) and who have no  direct
or  indirect financial interest  in the operation of  the Plan (the "Independent
12b-1 Trustees").  In making  their decision  to adopt  the Plan,  the  Trustees
requested  from the  Distributor and  received such  information as  they deemed
necessary to make an informed determination as to whether or not adoption of the
Plan was  in the  best interests  of the  shareholders of  the Fund.  After  due
consideration   of  the  information  received,   the  Trustees,  including  the
Independent 12b-1 Trustees, determined that  adoption of the Plan would  benefit
the  shareholders of the Fund. InterCapital, as the then sole shareholder of the
Fund, approved the Plan on May 10, 1994, whereupon the Plan went into effect.
 
    Under the Plan and as required by Rule 12b-1, the Trustees will 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. The  Fund accrued  amounts
payable  to the Distributor under  the Plan, during the  fiscal year ended March
31, 1997, of $6,228,452. This  amount is equal to  payments required to be  paid
monthly  by the  Fund which  were computed at  the annual  rate of  0.80% of the
average daily net assets of  the Fund for the  fiscal period and was  calculated
pursuant  to clause (b) of the compensation  formula under the Plan. This amount
is treated by the Fund as an expense in the year it is accrued.
 
    The Plan was  adopted in order  to permit the  implementation of the  Fund's
method  of distribution. Under  this distribution method shares  of the Fund are
sold without a sales load  being deducted at the time  of purchase, so that  the
full amount of an investor's purchase payment will be invested in shares without
any  deduction  for  sales charges.  Shares  of the  Fund  may be  subject  to a
contingent deferred sales charge, payable to the Distributor, if redeemed during
the five years after their purchase.  DWR compensates its account executives  by
paying  them, from its own funds, commissions for the sale of the Fund's shares,
currently a gross  sales credit of  up to 4%  of the amount  sold and an  annual
residual  commission of  up to 0.20  of 1%  of the current  value (not including
reinvested dividends  or distributions)  of  the amount  sold. The  gross  sales
credit  is  a charge  which  reflects commissions  paid  by DWR  to  its account
executives and 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 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 opportunity costs, such as the gross sales credit and  an
assumed interest charge thereon ("carrying charge"). In the
 
                                       33
<PAGE>
Distributor's  reporting of the distribution expenses  to the Fund, 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 its 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.
 
    The  Fund paid 100%  of the $6,228,452  accrued under the  Plan for the year
ended March 31, 1997 to the  Distributor. The Distributor and DWR estimate  that
they  have spent, pursuant to the Plan,  $40,579,469 on behalf of the Fund since
the inception  of the  Fund.  It is  estimated that  this  amount was  spent  in
approximately  the  following ways:  (i) 4.59%  ($1,863,204) --  advertising and
promotional  expenses;  (ii)  0.31%  ($125,929)  printing  of  prospectuses  for
distribution  to other than current shareholders; and (iii) 95.10% ($38,590,336)
- -- other expenses, including the gross sales credit and the carrying charge,  of
which  3.72%  ($1,434,274)  represents  carrying  charges,  38.66% ($14,918,159)
represents commission credits to DWR branch offices for payments of  commissions
to  account executives  and 57.62%  ($22,237,903) represents  overhead and other
branch office distribution-related expenses.
 
    At any given time, the  expenses of 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
the  excess 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  shares, totalled $28,870,822 as  of March 31, 1997.  Because
there  is no requirement under  the Plan that the  Distributor be reimbursed for
all distribution expenses  or any requirement  that the Plan  be continued  from
year  to year, 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  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 nor any  Trustee of the Fund who is not an
interested person of the Fund, as defined in the Act, has any direct or indirect
financial interest in the operation  of the Plan except  to the extent that  the
Distributor,  InterCapital, DWR or  certain of their employees  may be deemed to
have such  an interest  as a  result  of benefits  derived from  the  successful
operation  of the  Plan or  as a result  of receiving  a portion  of the amounts
expended thereunder by the Fund.
 
    Under its terms, the Plan remained in  effect until April 30, 1995 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. The  most
recent  continuance of the Plan for one year, until April 30, 1998, was approved
by the Board of Trustees  of the Fund, including  a majority of the  Independent
12b-1  Trustees, at a Board  meeting held on April  24, 1997. Prior to approving
the continuation  of the  Plan, the  Trustees requested  and received  from  the
Distributor  and reviewed  all the  information which  they deemed  necessary to
arrive at an informed determination.  In making their determination to  continue
the  Plan, the Trustees considered: (1) the Fund's experience under the Plan and
whether such experience indicates that the Plan is operating as anticipated; (2)
the benefits the Fund had obtained, was obtaining and would be likely to  obtain
under  the Plan; and (3) what services  had been provided and were continuing to
be provided under the Plan  to the Fund and  its shareholders. Based upon  their
review,  the  Trustees of  the  Fund, including  each  of the  Independent 12b-1
Trustees, determined that continuation of the Plan would be in the best interest
of the Fund and would have a reasonable likelihood of continuing to benefit  the
Fund  and its shareholders. In the Trustees'  quarterly review of the Plan, they
will consider  its  continued  appropriateness and  the  level  of  compensation
provided herein.

    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
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 Independent 12b-1
Trustees or by a vote of a majority of the outstanding voting securities of  the
Fund (as defined in the Act) on not more than 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 Trustees shall be  committed to the discretion of  the
Independent Trustees.
 
DETERMINATION OF NET ASSET VALUE
 
    As stated in the Prospectus, short-term securities with remaining maturities
of  60 days or less at the time of purchase are valued at amortized cost, unless
the Trustees determine such  does not reflect the  securities' market value,  in
which  case these securities will be valued at their fair value as determined by
the  Trustees.  Other   short-term  debt   securities  will  be   valued  on   a
mark-to-market  basis until such time  as they reach a  remaining maturity of 60
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
that such price does not reflect their market value, in which case they will  be
valued  at their fair value as determined  by the Trustees. All other securities
and other assets  are valued at  their fair  value as determined  in good  faith
under procedures established by and under the supervision of the Trustees.
 
    The  net asset value per share of the  Fund is determined once daily at 4:00
p.m., New York time, on each day that  the New York Stock Exchange is open  (or,
on  days when  the New York  Stock Exchange closes  prior to 4:00  p.m., at such
earlier time) by taking  the value of  all assets of  the Fund, subtracting  its
liabilities,  dividing by the number of  shares outstanding and adjusting to the
nearest cent.  The New  York  Stock Exchange  currently observes  the  following
holidays:   New  Year's  Day,  Presidents'   Day,  Good  Friday,  Memorial  Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
 
    Generally, trading in foreign securities, as well as corporate bonds, United
States government  securities and  money  market instruments,  is  substantially
completed  each day at  various times prior to  the close of  the New York Stock
Exchange. The values of such securities used in computing the net asset value of
the Fund's shares  are determined as  of such times.  Foreign currency  exchange
rates  are also generally  determined prior to  the close of  the New York Stock
Exchange. Occasionally, events which  affect the values  of such securities  and
such exchange rates may occur between the times at which they are determined and
the  close of the New York Stock Exchange and will therefore not be reflected in
the computation of the  Fund's net asset value.  If events materially  affecting
the  value of  such securities occur  during such period,  then these securities
will be valued at their fair value as determined in good faith under  procedures
established by and under the supervision of the Trustees.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened  for the investor on the books of  the Fund and maintained by Dean Witter
Trust Company (the "Transfer  Agent"). This is an  open account in which  shares
owned  by the investor are credited by the Transfer Agent in lieu of issuance of
a share certificate. If a share certificate is desired, it must be requested  in
writing  for each transaction. Certificates are  issued only for full shares and
may be  redeposited in  the account  at  any time.  There is  no charge  to  the
investor  for  issuance  of  a certificate.  Whenever  a  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.
 
                                       35
<PAGE>
    AUTOMATIC INVESTMENT  OF DIVIDENDS  AND  DISTRIBUTIONS.   As stated  in  the
Prospectus,   all  income   dividends  and   capital  gains   distributions  are
automatically paid  in  full and  fractional  shares  of the  Fund,  unless  the
shareholder  requests that they be paid in  cash. Each purchase of shares of the
Fund is made upon the condition that the Transfer Agent is thereby automatically
appointed as agent of  the investor to receive  all dividends and capital  gains
distributions  on shares owned by the investor. Such dividends and distributions
will be paid, at  the net asset value  per share, in shares  of the Fund (or  in
cash  if the shareholder so requests) 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  charge,
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 the  Distributor,
which  will  be  forwarded  to  the  shareholder,  upon  the  receipt  of proper
instructions.
 
    TARGETED  DIVIDENDS.(SM)    In  states  where  it  is  legally  permissible,
shareholders  may also have all income dividends and capital gains distributions
automatically invested in shares  of a Dean Witter  Fund other than Dean  Witter
High  Income Securities.  Such investment  will be  made as  described above for
automatic investment in shares in shares of the Fund, at the net asset value per
share of  the selected  Dean Witter  Fund as  of the  close of  business on  the
payment  date of the dividend or  distribution. Shareholders of Dean Witter High
Income Securities  must be  shareholders 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, on a semi-monthly,
monthly  or quarterly basis, to  the Transfer Agent for  investment in shares of
the Fund. Shares purchased through EasyInvest will be added to the shareholder's
existing account at  the net asset  value calculated the  same business day  the
transfer  of  funds is  effected.  For further  information  or to  subscribe to
EasyInvest,  shareholders   should  contact   their   DWR  or   other   selected
broker-dealer account executive or the Transfer Agent.
 
    INVESTMENT  OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  As discussed in
the Prospectus,  any shareholder  who  receives a  cash payment  representing  a
dividend  or distribution  may invest such  dividend or distribution  at the net
asset value next  determined after receipt  by the Transfer  Agent, without  the
imposition  of a contingent deferred sales  charge upon redemption, by returning
the check or the proceeds to the Transfer Agent within 30 days after the payment
date. If the  shareholder returns the  proceeds of a  dividend or  distribution,
such  funds  must  be accompanied  by  a  signed statement  indicating  that the
proceeds constitute a dividend or  distribution to be invested. Such  investment
will  be made at the net asset value  per share next determined after receipt of
the check or proceeds by the Transfer Agent.
 
    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  contingent deferred  sales  charge  will  be
imposed  on  shares redeemed  under the  Withdrawal  Plan (see  "Redemptions and
Repurchases--Contingent Deferred Sales  Charge" in  the Prospectus).  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
deferred sales charge)  to the  shareholder will  be the  designated monthly  or
quarterly amount.
 
    The  Transfer Agent acts as an 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
 
                                       36
<PAGE>
option, on the tenth or twenty-fifth day (or next following business day) of the
relevant  month or quarter and normally a  check for the proceeds will be mailed
by the Transfer Agent  within five business days  after the date of  redemption.
The Withdrawal Plan may be terminated at any time by the Fund.
 
    Withdrawal  Plan payments should  not be considered  as dividends, yields or
income. If periodic withdrawal plan payments continuously exceed net  investment
income  and net  capital gains,  the shareholder's  original investment  will be
correspondingly reduced and ultimately exhausted.
 
    Each withdrawal constitutes  a redemption  of shares  and any  gain or  loss
realized  must  be  recognized for  Federal  income tax  purposes.  Although the
shareholder may  make  additional  investments  of  $2,500  or  more  under  the
Withdrawal  Plan,  withdrawals made  concurrently  with purchases  of additional
shares may  be  inadvisable because  of  the contingent  deferred  sales  charge
applicable  to the redemption of shares purchased during the preceding six years
(see "Redemptions and Repurchases -- Contingent Deferred Sales Charge").
 
    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 nomination to the Transfer Agent.  In
addition,  the party and/or  the address to  which the checks  are mailed may be
changed by written notification to the Transfer Agent, with signature guarantees
required in the manner described above.  The shareholder may also terminate  the
Withdrawal  Plan at  any time by  written notice  to the Transfer  Agent. In the
event  of  such  termination,  the  account  will  be  continued  as  a  regular
shareholder  investment account. The shareholder may  also redeem all or part of
the  shares  held  in  the   Withdrawal  Plan  account  (see  "Redemptions   and
Repurchases" in the Prospectus) at any time.
 
    DIRECT  INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
a shareholder may  make additional  investments in Fund  shares at  any time  by
sending  a check in any amount, not less  than $100, payable to Dean Witter High
Income Securities, directly to the Fund's  Transfer Agent. Such amounts will  be
applied  to the purchase  of Fund shares at  the net asset  value per share next
computed after receipt of the check  or purchase payment by the Transfer  Agent.
The shares so purchased will be credited to the investor's account.
 
EXCHANGE PRIVILEGE
 
    As discussed in the Prospectus, the Fund makes available to its shareholders
an Exchange Privilege whereby shareholders of the Fund may exchange their shares
for  shares of  other Dean  Witter Funds sold  with a  contingent deferred sales
charge ("CDSC funds"), and  for shares of Dean  Witter Short-Term U.S.  Treasury
Trust,  Dean Witter Intermediate  Term U.S. Treasury  Trust, Dean Witter Limited
Term Municipal Trust,  Dean Witter  Short-Term Bond Fund,  Dean Witter  Balanced
Growth  Fund, Dean Witter Balanced Income Fund  and five Dean Witter Funds which
are money  market funds  (the foregoing  eleven non-CDSC  funds are  hereinafter
referred  to as the "Exchange Funds"). Exchanges may be made after the shares of
the Fund acquired by  purchase (not by exchange  or dividend reinvestment)  have
been  held for thirty days.  There is no waiting  period for exchanges of shares
acquired by exchange or dividend reinvestment.  An exchange 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.
 
                                       37
<PAGE>
    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  captions "Exchange
Privilege" and "Contingent Deferred Sales  Charge", a contingent deferred  sales
charge  ("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 the  Fund or any
other 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 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 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 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 CDSC
fund.
 
    In addition, shares of the  Fund may be acquired  in exchange for shares  of
Dean  Witter Funds sold  with a front-end sales  charge ("front-end sales charge
funds"), but shares  of the  Fund, however acquired,  may not  be exchanged  for
shares  of  front-end sales  charge funds.  Shares  of a  CDSC fund  acquired in
exchange for shares of a front-end sales charge fund (or in exchange for  shares
of  other Dean Witter  Funds for which  shares of a  front-end sales charge fund
have been exchanged) are not subject to any CDSC upon their redemption.
 
    If shares of the Fund are exchanged for shares of another CDSC fund having a
CDSC which  is imposed  at a  higher  rate or  is subject  to a  different  time
schedule  than the CDSC  imposed upon a redemption  of a share  of the Fund, the
higher CDSC will  be imposed  upon redemption of  shares of  the fund  exchanged
into.  Likewise, if shares of another CDSC  fund are exchanged for shares of the
Fund, upon rdemption of shares of the Fund, a CDSC will be imposed in accordance
with the CDSC schedule applicable to the fund with the higher CDSC. Moreover, if
shares of  the  Fund are  exchanged  for shares  of  another CDSC  fund  with  a
different  CDSC schedule imposing  a higher CDSC  and are subsequently exchanged
again for shares of  the Fund, the  higher CDSC will  still apply upon  ultimate
redemption of shares of the Fund.
 
    When  shares initially purchased in a CDSC  fund are exchanged for shares of
another CDSC fund, or for  shares of an Exchange Fund,  the date of purchase  of
the shares of the fund exchanged into, for purposes of the CDSC upon redemption,
will  be the  last day  of the month  in which  the shares  being exchanged were
originally purchased.  In allocating  the purchase  payments between  funds  for
purposes of the CDSC, the amount which represents the current net asset value of
shares  at the time of the exchange which  were (i) purchased more than three or
six years (depending on the CDSC schedule applicable to the shares) prior to the
exchange,  (ii)  originally  acquired  through  reinvestment  of  dividends   or
distributions  and  (iii) acquired  in exchange  for  shares of  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 (all such shares called "Free
Shares"), will be  exchanged first. Shares  of Dean Witter  American Value  Fund
acquired  prior  to  April  30,  1984, shares  of  Dean  Witter  Dividend Growth
Securities Inc. and  Dean Witter  Natural Resource  Development Securities  Inc.
acquired  prior  to July  2, 1984,  and  shares of  Dean Witter  Strategist Fund
acquired prior to November 8, 1989, are also considered Free Shares and will  be
the  first Free Shares to be exchanged.  After an exchange, all dividends earned
on shares in an Exchange Fund
 
                                       38
<PAGE>
will be considered  Free Shares. If  the exchanged amount  exceeds the value  of
such  Free Shares, an exchange  is made, on a  block-by-block basis, of non-Free
Shares held for  the longest  period of  time (except  that if  shares held  for
identical  periods of time but  subject to different CDSC  schedules are held in
the same Exchange Privilege account, the  shares of that block that are  subject
to  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 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
"Contingent Deferred Sales Charge," any applicable CDSC will be imposed upon the
ultimate redemption of shares of any fund, regardless of the number of exchanges
since those shares were originally purchased.
 
    With respect to  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 is $5,000 for
Dean Witter Liquid  Asset Fund Inc.,  Dean Witter Tax-Free  Daily Income  Trust,
Dean  Witter California  Tax-Free Daily  Income Trust  and Dean  Witter New York
Municipal Money Market  Trust, although  those funds may,  at their  discretion,
accept  initial  investments of  as  low as  $1,000.  The minimum  investment is
$10,000 for Dean Witter Short-Term U.S.  Treasury Trust, although that fund,  in
its  discretion,  may accept  initial purchases  as low  as $5,000.  The minimum
initial investment is  $5,000 for Dean  Witter Special Value  Fund. The  minimum
initial  investment  for all  other  Dean Witter  Funds  for which  the Exchange
Privilege is available  is $1,000.)  Upon exchange  into an  Exchange Fund,  the
shares  of  that fund  will  be held  in  a special  Exchange  Privilege Account
separately from accounts of  those shareholders who  have acquired their  shares
directly  from that  fund. As a  result, certain services  normally available to
shareholders of those funds,  including the check writing  feature, will not  be
available for funds held in that account.
 
    The  Fund and each  of the other Dean  Witter Funds may  limit the number of
times this  Exchange  Privilege  may  be exercised  by  any  investor  within  a
specified  period of  time. Also,  the Exchange  Privilege may  be terminated or
revised at any time by  the Fund and/or any of  the Dean Witter Funds for  which
shares  of the Fund have been exchanged, upon  such notice as may be required by
applicable regulatory agencies (presently sixty  days' prior written notice  for
termination  or  material revision),  provided  that six  months'  prior written
notice of  termination will  be given  to the  shareholders who  hold shares  of
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
 
                                       39
<PAGE>
closed for other than customary weekends and holidays, (b) when trading on  that
Exchange  is  restricted, (c)  when an  emergency  exists as  a result  of which
disposal by the Fund of securities owned by it is not reasonably practicable  or
it  is not reasonably practicable for the  Fund fairly to determine the value of
its net assets,  (d) during any  other period when  the Securities and  Exchange
Commission  by order so permits (provided  that applicable rules and regulations
of the  Securities  and Exchange  Commission  shall  govern as  to  whether  the
conditions prescribed in (b) or (c) exist) or (e) if the Fund would be unable to
invest amounts effectively in accordance with its investment objective, 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 the Fund can be redeemed
for  cash at any time at the net asset value per share next determined; however,
such redemption  proceeds  may  be  reduced by  the  amount  of  any  applicable
contingent  deferred  sales  charges  (see  below).  If  shares  are  held  in a
shareholder's account  without  a  share  certificate,  a  written  request  for
redemption  to the Fund's Transfer Agent at  P.O. Box 983, Jersey City, NJ 07303
is required. If  certificates are  held by the  shareholder, 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 certificates, 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.  The term "good  order" means  that the  share
certificate, if any, and request for redemption are properly signed, accompanied
by  any  documentation  required  by  the  Transfer  Agent,  and  bear signature
guarantees when required  by the Fund  or the Transfer  Agent. If redemption  is
requested  by a corporation, partnership, trust or fiduciary, the Transfer Agent
may require that written evidence of authority acceptance to the Transfer  Agent
be submitted before such request is accepted.
 
    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. 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 a means of a new prospectus.
 
    CONTINGENT DEFERRED SALES CHARGE.  As stated in the Prospectus, a contingent
deferred sales charge ("CDSC") will be imposed on any redemption by an  investor
if  after such redemption the current value of the investor's shares of the Fund
is less  than the  dollar amount  of all  payments by  the shareholder  for  the
purchase  of Fund shares during the preceding  five 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 five
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 five  years.
The CDSC will be paid to the Distributor.

    In  determining the applicability  of a 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 five  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 five 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. Any portion of the amount redeemed which exceeds an amount which
represents both such increase  in value and the  value of shares purchased  more
than  five  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.
 
    In  addition, the CDSC, if otherwise applicable,  will be waived in the case
of: (i) redemptions of  shares held at  the time a  shareholder dies or  becomes
disabled,  only  if the  shares  are (a)  registered either  in  the name  of an
individual shareholder (not a  trust), or in the  names of such shareholder  and
his  or her spouse as joint tenants with right of survivorship, or (b) held in a
qualified corporate  or  self-employed retirement  plan,  Individual  Retirement
Account  or Custodial  Account under Section  403(b)(7) of  the Internal Revenue
Code, provided in either case that  the redemption is requested within one  year
of  the death  or initial determination  of disability, and  (ii) redemptions in
connection with the  following retirement  plan distributions:  (a) lump-sum  or
other  distributions from a qualified corporate of self-employed retirement plan
following retirement (or in the case of a "key employee" of a "top heavy"  plan,
following  attainment  of  age 59  1/2);  (b) distributions  from  an Individual
Retirement Account or Custodial Account under Section 403(b)(7) of the  Internal
Revenue Code following attainment of age 59 1/2; and (c) a tax-free return of an
excess  contribution to an  IRA. For the purpose  of determining disability, the
Distributor utilizes the definition of disability contained in Section  72(m)(7)
of the Code, which relates to the inability to engage in gainful employment. All
waivers   will  be  granted  only  following   receipt  by  the  Distributor  of
confirmation of the investor's entitlement.
 
    The amount of the CDSC, if any,  will vary depending on the number of  years
from  the time  of payment  for the purchase  of Fund  shares 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, 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:

</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 five-year period. This will result in any such CDSC being imposed  at
the   lowest  possible  rate.  Accordingly,  shareholders  may  redeem,  without
incurring any CDSC,  amounts equal to  any net  increase in the  value of  their
shares  above the amount  of their purchase  payments made within  the past five
years and amounts equal to the current value of shares purchased more than  five
years  prior  to the  redemption and  shares  purchased through  reinvestment of
dividends or distributions  or 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. The  CDSC will be
imposed, in accordance  with the table  shown above, on  any redemptions  within
five  years  of  purchase  which  are  in  excess  of  these  amounts  and which
redemptions
 
                                       41
<PAGE>
are not  (a) requested  within one  year of  death or  initial determination  of
disability   of  a  shareholder,  or  (b)   made  pursuant  to  certain  taxable
distributions from retirement plans or retirement accounts, as described above.
 
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment for shares presented for repurchase or redemption will be made by  check
within  seven days after receipt by the Transfer Agent of the certificate and/or
written request  in good  order. The  term  "good order"  means that  the  share
certificate,   if  any,  and  request   for  redemption,  are  properly  signed,
accompanied by  any  documentation required  by  the Transfer  Agent,  and  bear
signature  guarantees  when required  by the  Fund or  the Transfer  Agent. Such
payment may be postponed or the right of redemption suspended at times (a)  when
the  New York  Stock Exchange  is closed for  other than  customary weekends and
holidays, (b) when trading on that Exchange is restricted, (c) when an emergency
exists as a result of  which disposal by the Fund  of securities owned by it  is
not  reasonably practicable  or it  is not  reasonably practicable  for the Fund
fairly to determine the value of its  net assets, or (d) during any period  when
the  Securities  and  Exchange Commission  by  order so  permits;  provided that
applicable rules and 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  the  check  by  the  Transfer  Agent).  Shareholders
maintaining  margin  accounts with  DWR  or another  selected  broker-dealer are
referred to  their account  executive regarding  restrictions on  redemption  of
shares of the Fund pledged in the margin account.
 
    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  contingent deferred sales charge  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 of 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 contingent  deferred sales  charge 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 30 days after the  redemption
or  repurchase, reinstate any portion or all  of the proceeds of such redemption
or repurchase in shares  of the Fund  held by the shareholder  at the net  asset
value next determined after a reinstatement request, together with the proceeds,
is received by the Transfer Agent.
 
    Exercise  of the reinstatement privilege will  not affect the federal income
tax and  state income  tax  treatment of  any gain  or  loss realized  upon  the
redemption  or repurchase, except that if  the redemption or repurchase resulted
in a loss and reinstatement is  made in shares of the  Fund, some or all of  the
loss, depending on the amount reinstated, will not be allowed as a deduction for
federal income tax and state personal income tax purposes but will be applied to
adjust the cost basis of the shares acquired upon reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    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. 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
 
                                       42
<PAGE>
required  for federal income tax purposes.  Additionally, with respect to market
discounts on bonds  issued after July  18, 1984, and  all bonds purchased  after
April  30, 1993, a portion of any  capital gain realized upon disposition may be
re-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. Dividend income is recorded on the
ex-dividend date. Gains or losses on the 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. In determining
amounts  to be  distributed, capital  gains will be  offset by  any capital loss
carryovers incurred in prior  years. The Fund incurred  and will elect to  defer
net capital losses of approximately $6,272,000 during fiscal year 1997.
 
    Any dividend or capital gains distribution received by a shareholder from an
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 some
portion of the 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 realized long-term capital gains, such payment 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 taxable to the
shareholder. Therefore,  an investor  should consider  the tax  implications  of
purchasing Fund shares immediately prior to a distribution record date.
 
    Shareholders  should  consult  their  attorneys  or  tax  advisers regarding
specific questions as to state or local taxes and as to the applicability of the
foregoing to their current federal tax situation.
 
    SPECIAL RULES FOR CERTAIN FOREIGN CURRENCY TRANSACTIONS.  In general,  gains
from  foreign  currencies and  from foreign  currency options,  foreign currency
futures and forward foreign exchange contracts relating to investments in stock,
securities or  foreign  currencies are  currently  considered to  be  qualifying
income  for purposes  of determining whether  the Fund qualifies  as a regulated
investment company. It is currently unclear, however, who will be treated as the
issuer of certain foreign currency instruments or how foreign currency  options,
futures,  or forward foreign  currency contracts will be  valued for purposes of
the regulated investment company diversification requirements applicable to  the
Fund.  The Fund may  request a private  letter ruling from  the Internal Revenue
Service on some or all of these issues.
 
    Under Code Section 988, special rules are provided for certain  transactions
in  a  foreign currency  other than  the  taxpayer's functional  currency (I.E.,
unless certain special rules apply, currencies  other than the U.S. dollar).  In
general,  foreign currency gains or losses  from forward contracts, from futures
contracts that are not "regulated futures contracts", and from unlisted  options
will be treated as ordinary income or loss under Code Section 988. Also, certain
foreign  exchange gains or  losses derived with  respect to foreign fixed-income
securities are also  subject to  Section 988 treatment.  In general,  therefore,
Code  Section 988 gains  or losses will  increase or decrease  the amount of the
Fund's  investment  company  taxable  income  available  to  be  distributed  to
shareholders as ordinary income, rather than increasing or decreasing the amount
of  the Fund's net capital gain. Additionally, if Code Section 988 losses exceed
other investment company taxable  income during a taxable  year, the Fund  would
not be able to make any ordinary dividend distributions.
 
    If  the Fund invests in an entity  which is classified as a "passive foreign
investment company" ("PFIC") for U.S.  tax purposes, the application of  certain
technical  tax  provisions  applying  to  such  companies  could  result  in the
imposition of federal income  tax with respect to  such investments at the  Fund
level  which could not be eliminated  by distributions to shareholders. The U.S.
Treasury issued  proposed  regulation  section 1.1291-  8  which  establishes  a
mark-to-market  regime which allows investment  companies investing in PFIC's to
avoid most, if  not all, of  the difficulties posed  by the PFIC  rules. In  any
event,  it  is  not anticipated  that  any taxes  on  the Fund  with  respect to
investments in PFIC's would be significant.
 
    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
"yield" and/or its "total return" in advertisements and sales literature.  Yield
is  calculated for any 30-day  period as follows: the  amount of interest and/or
dividend income  for each  security in  the Fund's  portfolio is  determined  in
accordance  with  regulatory requirements;  the total  for the  entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during  the
period are subtracted to arrive at "net investment income". The resulting amount
is  divided by the product of  the net asset value per  share on the last day of
the period multiplied by  the average number of  Fund shares outstanding  during
the period that were entitled to dividends. This amount is added to 1 and raised
to  the sixth power. 1 is then subtracted  from the result and the difference is
multipled by 2  to arrive  at the annualized  yield. For  the thirty-day  period
ended  March  31, 1997,  the Fund's  yield, calculated  pursuant to  the formula
described above, was 8.59%.
 
    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 contingent deferred sales charge 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
the Fund for the  fiscal year ended March  31, 1997 and for  the period June  2,
1994 through March 31, 1997 were 6.76% and 9.56%, respectively.
 
    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time by means of aggregate, average, year-by-year or  other
types  of total  return figures.  Such calculations may  or may  not reflect the
deduction of the contingent  deferred charge which,  if reflected, would  reduce
the  performance quoted.  For example, the  average annual total  returns of the
Fund may be calculated in the manner described above, but without deduction  for
any  applicable contingent deferred  sales charge. Based  upon this calculation,
the average annual total return of the Fund for the fiscal year ended March  31,
1997  and for  the period June  2, 1994 through  March 31, 1997  were 10.71% and
31.43%, respectively.
 
    In addition, the Fund may compute  its aggregate total return for  specified
periods  by determining the  aggregate percentage rate which  will result in the
ending value of a  hypothetical $1,000 investment made  at the beginning of  the
period.  For the purpose of  this calculation, it is  assumed that all dividends
and distributions  are reinvested.  The formula  for computing  aggregate  total
return  involves a percentage obtained by dividing the ending value (without the
reduction for  any  contingent deferred  sales  charge) by  the  initial  $1,000
investment  and  subtracting  1  from  the  result.  Based  upon  the  foregoing
calculation, the aggregate total  return of the Fund  for the fiscal year  ended
March  31, 1997  and for  the period June  2, 1994  through March  31, 1997 were
10.71% and 10.14%, respectively.
 
    The Fund  may  also advertise  the  growth of  hypothetical  investments  of
$10,000,  $50,000 and $100,000 in  shares of the Fund by  adding 1 to the Fund's
total aggregate total return to date (expressed as a decimal and without  taking
into  account the effect of applicable CDSC) and multiplying by $10,000, $50,000
or $100,000 as the case may be.  Investments of $10,000, $50,000 or $100,000  in
the  Fund at  the commencement  of its operations  would have  grown to $13,143,
$65,715 and $131,430, respectively, by March 31, 1997.
 
    The Fund from time  to time may also  advertise its performance relative  to
certain performance rankings and indexes compiled by independent organizations.

DESCRIPTION OF SHARES
- --------------------------------------------------------------------------------
 
    The shareholders of the Fund are entitled to a full vote for each full share
held.  All of the  Trustees have been  elected by the  shareholders of the Fund,
most recently at a Special Meeting of Shareholders held on May 21, 1997. On that
date, Wayne E. Hedien was also elected as a Trustee of the Fund with his term to
commence on September 1, 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 to  remove the  Trustees  following a  meeting called  for  that
purpose  requested in writing by the record holders of not less than ten percent
of the Fund's  outstanding shares.  The voting  rights of  shareholders are  not
cumulative, so that holders of more than 50 percent of the shares voting can, if
they  choose,  elect  all Trustees  being  selected,  while the  holders  of the
remaining shares would be unable to elect any Trustees.
 
    The Declaration of Trust permits the  Trustees to authorize the creation  of
additional  series  of  shares  (the  proceeds of  which  would  be  invested in
separate, independently  managed portfolios)  and additional  classes of  shares
within  any  series (which  would be  used  to distinguish  among the  rights of
different categories of shareholders, as might be required by future regulations
or other unforeseen circumstances). The  Trustees presently have not  authorized
any such additional series or classes of shares.
 
    The  Declaration of  Trust provides  that no  Trustee, officer,  employee or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer, employee or agent  liable to any third  persons in connection with  the
affairs  of the Fund, except as such liability may arise from his or her own bad
faith, willful misfeasance, gross  negligence, or reckless  disregard of his  or
her  duties. It also  provides that all  third persons shall  look solely to the
Fund's property  for  satisfaction of  claims  arising in  connection  with  the
affairs  of  the Fund.  With  the exceptions  stated,  the Declaration  of Trust
provides  that  a  Trustee,  officer,  employee  or  agent  is  entitled  to  be
indemnified against all liabilities in connection with the affairs of the Fund.
 
    The  Fund is authorized to issue an unlimited number of shares of beneficial
interest. The Fund shall be of  unlimited duration subject to the provisions  in
the Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER HIGH INCOME SECURITIES
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER HIGH INCOME SECURITIES
 
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 High Income Securities
(the "Fund") at March 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 two years in the period
then ended and for the period June 2, 1994 (commencement of operations) through
March 31, 1995, 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 March
31, 1997 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter High Income Securities (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's primary investment objective
is to earn a high level of current income and, as a secondary objective, capital
appreciation, but only when consistent with its primary objective. The Fund
seeks to achieve its objective by investing primarily in lower-rated fixed
income securities. The Fund was organized as a Massachusetts business trust on
March 23, 1994 and commenced operations on June 2, 1994.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) 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 a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (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
and bid prices are not reflective of a security's market value, portfolio
securities are valued at their fair value as determined in good faith under
procedures established by and under the general supervision of the 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 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
 
                                       57
<PAGE>
DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
on a mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.
 
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 ex-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.
 
E. ORGANIZATIONAL EXPENSES -- The Investment Manager paid the organizational
expenses of the Fund in the amount of approximately $154,000 which haven been
reimbursed for the full amount thereof. Such expenses have been deferred and are
being amortized on the straight-line method over a period not to exceed five
years from the commencement of operations.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement, the Fund pays the Investment
Manager a management fee, calculated daily and payable monthly, by applying the
annual rate of 0.50% to the net assets of the Fund determined as of the close of
each business day. Effective May 1, 1996, the annual rate was reduced to 0.425%
for net assets in excess of $500 million.

<PAGE>
DEAN WITTER HIGH INCOME SECURITIES
NOTES TO FINANCIAL STATEMENTS MARCH 31, 1997, CONTINUED
 
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 pursuant
to which the Fund pays the Distributor compensation, accrued daily and payable
monthly, at an annual rate of 0.80% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's shares since the Fund's inception (not
including reinvestment of dividend or capital gain distributions) less the
average daily aggregate net asset value of the Fund's shares redeemed since the
Fund's inception upon which a contingent deferred sales charge has been imposed

assets. Amounts paid under the Plan are paid to the Distributor to compensate it
for the services provided and the expenses borne by it and others in the
distribution of the Fund's shares, including the payment of commissions for
sales of the Fund's shares and incentive compensation to, and expenses of, the
account executives of Dean Witter Reynolds Inc., an affiliate of the Investment
Manager and Distributor, and other employees or selected broker-dealers who

shareholder accounts, including overhead and telephone expenses, printing and
distribution of prospectuses and reports used in connection with the offering of

Dean Witter High Yield Securities Inc. 
Two World Trade Center 
New York, New York 10048 

Ladies and Gentlemen: 

   This opinion is being furnished to Dean Witter High Yield Securities Inc., 
a Maryland corporation (the "Corporation"), in connection with the 
Registration Statement on Form N-14 (the "Registration Statement") under the 
Securities Act of 1933, as amended (the "1933 Act"), to be filed by the 
Corporation in connection with the acquisition by the Corporation of 
substantially all the assets of Dean Witter High Income Securities ("High 
Income") in exchange for shares of common stock, par value $.01, of the 
Corporation ("Shares") and the assumption by the Corporation of certain 
stated liabilities of High Income pursuant to an Agreement and Plan of 
Reorganization dated as of June 30, 1997, between the Corporation and High 
Income (the "Reorganization Agreement"). We have examined such statutes, 
regulations, corporate records and other documents and reviewed such 
questions of law that we deemed necessary or appropriate for the purposes of 
this opinion. 

   As to matters of Maryland law contained in this opinion, we have relied 
upon the opinion of Piper & Marbury LLP, dated July 3, 1997. 

   Based upon the foregoing, we are of the opinion that the Shares when 
issued, as described in the Reorganization Agreement, will be duly authorized 
and, assuming receipt of the consideration to be paid therefor, upon delivery 
as provided in the Reorganization Agreement, will be legally issued, fully 
paid and non-assessable. 

   We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and to the reference to us under the caption "Legal 
Matters" in the Prospectus forming a part of the Registration Statement. We 
do not thereby admit that we are within the category of persons whose consent 
is required under Section 7 of the 1933 Act or the rules and regulations of 
the Securities and Exchange Commission thereunder.

                       Registration Statement on Form N-14
                       -----------------------------------
Gentlemen:

      We have acted as special Maryland counsel to Dean Witter High Yield
Securities Inc., a Maryland corporation ("High Yield"), in connection with
High Yield's Registration Statement on Form N-14 (the "Registration
Statement") to be filed with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Act"),
related to the transfer of substantially all of the assets of Dean Witter High
Income Securities, a Massachusetts business trust ("High Income"), to High 
Yield in exchange for the issuance of Class B shares, par value $.01 per share
(the "Class B Shares"), of High Yield and the assumption of High Income's 
liabilities by High Yield pursuant to the terms of an Agreement and Plan of 
Reorganization (the "Agreement") dated as of June 30, 1997, by and between
High Yield and High Income.

      In this capacity, we have examined the Registration Statement, the
Agreement, the Charter and By-Laws of High Yield, a short-form good standing
certificate (the "Certificate") from the State Department of Assessments and
Taxation of Maryland dated June 30, 1997, and such other statutes,
certificates, instruments, and documents relating to High Yield and matters of
law as we have deemed necessary to the issuance of this opinion. In such
examination, we have assumed, without independent investigation, the
genuineness of all signatures, the legal capacity of all individuals who have
executed any of the aforesaid documents, the authenticity of all documents
submitted to us as originals, the conformity with originals of all documents
submitted to us as copies (and the authenticity of the originals of such
copies), and all public records reviewed are accurate

and complete. As to factual matters, we have relied on the Certificate and 
have not independently verified the matters stated therein.

      We assume that prior to the issuance of any of the Class B Shares, there
will exist, under the Charter of High Yield, the requisite number of
authorized but unissued Class B Shares and that all actions necessary to the
creation of any Class B Shares, whether by Charter amendment or by
classification or reclassification of existing capital stock and the filing of
Articles Supplementary, will have been taken. We further assume that
appropriate certificates representing Class B Shares will be executed and
delivered upon issuance of any of the Class B Shares and will comply with all
applicable requirements of Maryland law and the Agreement. We assume that the
issuance, amount and terms of the Class B Shares will be authorized and
determined by proper action of the Board of Directors of High Yield ("Board
Action") in accordance with High Yield's Charter and By-Laws and with
applicable Maryland law and the Agreement. Finally, we assume that the
Agreement will be a valid and legally binding contract that conforms to the
description thereof set forth in the Registration Statement.

      Based upon the foregoing and having regard for such legal considerations
as we deem relevant, we are of the opinion that, as of the date hereof:

           1. High Yield is a corporation validly existing and in good standing
      under the laws of the State of Maryland.

           2. Upon due authorization by Board Action of the issuance of the
      Class B Shares and upon issuance and delivery of certificates for the
      Class B Shares against payment therefor in accordance with the terms and
      provisions of such Board Action, the Registration Statement (as declared
      effective under the Act), and the Agreement, the Class B Shares will have
      been duly and validly authorized and will be validly issued, fully paid,
      and non-assessable.

      The opinion expressed herein is solely for (i) the use of High Yield in
connection with the Registration Statement, and (ii) the use of Gordon Altman
Butowsky Weitzen Shalov & Wein in giving their legality opinion to be filed as
an exhibit to the Registration Statement. This opinion may not be relied on by
any other person or in any other connection without our prior written
approval. This opinion is limited to the matters set forth herein, and no
other opinion should be inferred beyond the matters expressly stated.

Dean Witter High Income Securities

Dean Witter High Yield Securities Inc.
Two World Trade Center
New York, NY 10048

Gentlemen:

                  You have requested our opinion as to the Federal income tax
consequences of the transaction (the "Reorganization") described below pursuant
to which substantially all assets of (i) Dean Witter High Income Securities ("
High Income"), will be combined with those of Dean Witter High Yield Securities
Inc. ("High Yield"), in exchange for shares of High Yield, and the assumption by
High Yield of certain liabilities of High Income (the "Liabilities"), (ii) High
Income will be liquidated, and (iii) the High Yield Shares will be distributed
to the holders ("High Income Shareholders") of shares in High Income ("High
Income Shares") pursuant to such liquidation.

                  We have examined and are familiar with such documents, records
and other instruments as we have deemed appropriate for purposes of this opinion
letter, including the Registration Statement being filed with the Securities and
Exchange Commission under the Securities Act of 1933 on Form N-14, relating to
the High Yield Shares (the "Registration Statement") which includes, as a part
thereof, the proxy statement of High Income (the "High Income Proxy") which will
be used to solicit proxies of Shareholders in connection with the Special
Meeting of High Income Shareholders and the proposed Agreement and Plan of
Reorganization by and between High Income and High Yield (the "Plan"). In
rendering this opinion, we have assumed that such documents as yet unexecuted
will, when executed, conform to the proposed forms of such documents that we
have examined. We have further assumed that the Reorganization will be carried
out pursuant to the terms of the Plan, that factual statements and information
contained in the Registration Statement, the High Income Proxy and other
documents, records, and instruments supplied to us are correct and that there
will be no material change with respect to such facts or information prior to
the time of the Reorganization. In rendering our opinion we have also relied on
the representations and facts discussed below which


<PAGE>



June 30, 1997
Page 2





have been provided to us by Dean Witter Intercapital Inc ("Dean Witter"), High
Yield and High Income, and we have assumed that such representations and facts
will remain correct at the time of the Reorganization.


                                      FACTS


                  High Yield is an open-end diversified management investment
company engaged in the continuous offering of its shares to the public. Since
its inception, High Yield has conducted its affairs so as to qualify, and has
elected to be taxed, as a regulated investment company under Section 851 of the
Internal Revenue Code of 1986, as amended (the "Code").

                  High Income is an open-end diversified management investment
company engaged in the continuous offering of its shares to the public. Since
its inception, High Income has conducted its affairs so as to qualify, and has
elected to be taxed, as a regulated investment company under Section 851 of the
Code.

                  The Board of Directors of High Yield and of High Income have
each determined, for valid business reasons, that it is advisable to combine the
assets of High Income and High Yield into one fund.

                  In view of the above, the Board of Directors of High Income
adopted the Plan, subject to, among other things, approval by High Income
Shareholders.

                  Pursuant to the Plan, High Income will transfer all of its
assets to High Yield in exchange for the High Yield Shares (including fractional
High Yield Shares) and the assumption by High Yield of the Liabilities.
Immediately thereafter, High Income will distribute the High Yield Shares to
High Income Shareholders in exchange for and in cancellation of their High
Income Shares and in complete liquidation of High Income.

                  Each of the following representations, among other
representations, has been made to us in connection with the Reorganization by
Dean Witter, High Income and High Yield.

                  (1) To the best of the knowledge of the management of Dean
Witter, High

Income, High Yield, and their affiliates (collectively, "Management"), there is
no plan or intention on the part of High Income Shareholders, to redeem, sell,
exchange or otherwise dispose of a number of High Yield Shares that would reduce
High Income Shareholders' ownership of High Yield Shares to a number of High
Yield Shares having a value, as of the date of the Reorgani zation, of less than
50 percent of the value of all of the formerly outstanding High Income Shares as
of such date;

                  (2) High Yield has no plan or intention to reacquire any of
the High Yield Shares to be issued pursuant to the Reorganization except to the
extent necessary to comply with its legal obligation to redeem its own shares;

                  (3) The Liabilities to be assumed by or transferred to High
Yield were incurred by High Income in the ordinary course of business and are
associated with the assets being transferred to High Yield;

                  (4) The amount of the Liabilities will not exceed the
aggregate adjusted basis of High Income for its assets transferred to High
Yield;

                  (5) High Yield has no plan or intention to sell or otherwise
dispose of more than fifty percent of the assets of High Income acquired in the
Reorganization, except for dispositions made in the ordinary course of business;

                  (6) There is no indebtedness between High Income and High
Yield that was issued, acquired or will be settled at a discount;

                  (7) High Income has been a regulated investment company within
the meaning of Section 851 of the Code since the date of its organization
through the end of its last complete taxable year and will qualify as a
regulated investment company for its taxable year ending on the date of the
Reorganization;

                  (8) High Yield has been a regulated investment company within
the meaning of Section 851 of the Code since the date of its organization
through the date hereof and will qualify as a regulated investment company for
its taxable year ending August 31, 1997; and

                  (9) High Income will have no accumulated earnings and profits
as of the close of

its taxable year ending on the date of the Reorganization.


                                     OPINION


                  Based on the Code, Treasury Regulations issued thereunder,
Internal Revenue Service Rulings and the relevant case law, as of the date
hereof, and on the facts, representations and assumptions set forth above, and
the documents, records and other instruments we have reviewed, it is our opinion
that the Federal income tax consequences of the Reorganization to High Yield,
High Income, and the High Income Shareholders will be as follows:

                  (1) The transfer of substantially all of High Income's assets
in exchange for High Yield Shares and the assumption by High Yield of certain
stated Liabilities of High Income, followed by the distribution by High Income
of the High Yield Shares to the High Income Shareholders in exchange for their
High Income Shares, will constitute a "reorganization" within the meaning of
Section 368(a)(1) of the Code, and High Income and High Yield will each be a
"party to a reorganization" within the meaning of Section 368(b) of the Code;

                  (2) No gain or loss will be recognized by High Yield upon the
receipt of the assets of High Income solely in exchange for High Yield Shares
and the assumption of the Liabilities by High Yield of the stated liabilities of
High Income;

                  (3) No gain or loss will be recognized by High Income upon the
transfer of the assets of High Income to High Yield, in exchange for the High
Yield Shares and the assumption of the Liabilities by High Yield, or upon the
distribution of the High Yield Shares to High Income Shareholders in exchange
for their High Income Shares as provided in the Plan;

                  (4) No gain or loss will be recognized by High Income
Shareholders upon the exchange of their High Income Shares for the High Yield
Shares;

                  (5) The aggregate tax basis for the High Yield Shares received
by each High Income Shareholder pursuant to the Reorganization will be the same
as the aggregate tax basis of the High Income Shares held by each such High
Income Shareholder immediately prior to the Reorganization;


<PAGE>



June 30, 1997
Page 5




                  (6) The holding period of the High Yield Shares to be received
by each High Income Shareholder will include the period during which the High
Income Shares surrendered in exchange therefor were held (provided such High
Income Shares were held as capital assets on the date of the Reorganization);

                  (7) The tax basis of the assets of High Income acquired by
High Yield will be the same as the tax basis of such assets to High Income
immediately prior to the Reorganization; and

                  (8) The holding period of the assets of High Income in the
hands of High Yield will include the period during which those assets were held
by High Income.

                  We are not expressing an opinion as to any aspect of the
Reorganization other than those opinions expressly stated above.

                  As noted above, this opinion is based upon our analysis of the
Code, Treasury Regulations issued thereunder, Internal Revenue Service Rulings
and case law which we deem relevant as of the date hereof. No assurances can be
given that there will not be a change in the existing law or that the Internal
Revenue Service will not alter its present views, either prospectively or
retroactively, or adopt new views with regard to any of the matters upon which
we are rendering this opinion, nor can any assurances be given that the Internal
Revenue Service will not audit or question the treatment accorded to the
Reorganization on the Federal income tax returns of High Yield, High Income, or
the High Income Shareholders.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the use of our name and any reference to
our firm in the Registration Statement and the High Income Proxy constituting a
part thereof.

                                                     Very truly yours,
