primary investment objective is to earn a high level of current income. As a
secondary objective, the fund seeks capital appreciation but only to the extent
consistent with its primary objective. The fund seeks to achieve its objective
by investing at least 80% of its assets in fixed-income securities rated lower
than Baa by Moody's Investors Service or lower than BBB by Standard & Poor's
Corporation or in non-rated securities considered by the fund's investment
manager, Morgan Stanley Investment Advisors Inc., to be appropriate investments
for the fund.


     This Proxy Statement and Prospectus sets forth concisely information about
High Yield that shareholders of HIAT III should know before voting on the
Reorganization Agreement. A copy of the Prospectus for High Yield dated
September 30, 2002, is attached as Exhibit B and incorporated herein by
reference. Also enclosed and incorporated herein by reference is High Yield's

Additional Information relating to the Reorganization, described in this Proxy
Statement and Prospectus (the "Additional Statement"), dated October 3, 2002,

Report for the six months ended July 31, 2002. Such documents are available
without charge by calling (800) 869-NEWS (toll free).


Investors are advised to read and retain this Proxy Statement and Prospectus

EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE SECURITIES

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 HIAT III at 1221 Avenue of the
Americas, New York, New York 10020; (ii) attending the Meeting and voting in
person; or (iii) completing and returning a new proxy (whether by mail or, as
discussed below, by touchtone telephone or the Internet) (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 to permit further solicitation of proxies. Any such adjournment
will require the affirmative vote of the holders of a majority of shares of
HIAT III 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. Abstentions and broker "non-votes" will not count in
favor of or against any such vote for adjournment.


     Shareholders will be able to vote their shares by touchtone telephone or
by Internet by following the instructions on the proxy card or on the Voting
Information Card accompanying this Proxy Statement and Prospectus. To vote by
Internet or by telephone, Shareholders can access the website or call the
toll-free number listed on the proxy card or noted in the enclosed voting
instructions. To vote by Internet or by telephone, Shareholders will need the
"control number" that appears on the proxy card.


     In certain instances, Morgan Stanley Trust ("MS Trust"), an affiliate of
Morgan Stanley Investment Advisors Inc. ("MS Advisors" or the "Investment
Manager") or Alamo Direct Mail Services Inc. ("Alamo") may call Shareholders to
ask if they would be willing to have their votes recorded by telephone. The
telephone



                                       2



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. HIAT III has been advised by counsel that these procedures are
consistent with the requirements of applicable law. Shareholders voting by
telephone in this manner 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 set forth in the confirmation 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 Proxy
Statement and Prospectus and may vote by mail using the enclosed proxy card or
by touchtone telephone or the Internet as set forth above. The last proxy vote
received in time to be voted, whether by proxy card, touchtone telephone or
Internet, will be the last vote that is counted and will revoke all previous
votes by the Shareholder.


EXPENSES OF SOLICITATION


     The expenses of this solicitation, including the cost of preparing and
mailing this Proxy Statement and Prospectus, are expected to approximate
$100,000 and will be borne by HIAT III. HIAT III and High Yield will bear all
of their respective other expenses associated with the Reorganization. In
addition to the solicitation of proxies by mail, proxies may be solicited by
officers of HIAT III, and officers and regular employees of MS Advisors and MS
Trust, Morgan Stanley Services Company Inc. ("MS Services") and/or Morgan
Stanley DW Inc. ("Morgan Stanley DW"), affiliates of MS Advisors, personally or
by mail, telephone, telegraph or otherwise, without compensation therefor. In
addition, HIAT III will employ Alamo to make telephone calls to Shareholders to
remind them to vote. In addition, HIAT III may also employ D.F. King & Co.,
("D.F. King") as proxy solicitor if it appears that the required number of
votes to achieve quorum will not be received. In the event of a solicitation by
D.F. King, HIAT III would pay D.F. King $3,000 and the expenses outlined below.
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. With respect to the solicitation of
a telephonic vote by Alamo, expenses would be approximately $1.00 per outbound
telephone contact, which would be borne by HIAT III. With respect to the
solicitation of a telephonic vote by D.F. King, approximate additional expenses
may include $6.00 per telephone vote transacted, $3.25 per outbound or inbound
telephone contact, and costs relating to obtaining Shareholders' telephone
numbers and providing additional materials upon Shareholder requests, which
would be borne by HIAT III.



VOTE REQUIRED

     Approval of the Reorganization Agreement by the Shareholders requires the
vote of a majority of the outstanding shares of HIAT III which means an
affirmative vote of the lesser of (1) a majority of the outstanding shares of
HIAT III, or (2) 67% or more of the shares of HIAT III represented at the
Meeting if more than 50% of the outstanding shares of HIAT III are present or
represented by proxy. If the Reorganization Agreement is not approved by
Shareholders, HIAT III 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 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 HIAT III, 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 HIAT III received by High Yield. On or after the closing date of the
Reorganization, currently anticipated to be December 16, 2002, (the "Closing
Date"), HIAT III will distribute the High Yield Shares received by HIAT III to
Shareholders as of the Valuation Date (as defined below under "The
Reorganization Agreement") in complete liquidation of HIAT III and HIAT III
will thereafter be de-registered as an investment company under the Investment
Company Act of 1940, as amended (the "1940 Act") and dissolved under
Massachusetts law. 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 of HIAT III transferred
to High Yield. Accordingly, as a result of the Reorganization, each Shareholder
of HIAT III will become a holder of Class D shares of High Yield. Shareholders
holding their shares of HIAT III in certificate form will be asked to surrender
their certificates in connection with the Reorganization. Shareholders who do
not surrender their certificates prior to the Closing Date will still receive
their shares of High Yield; however, such Shareholders will not be able to
redeem, transfer or exchange the High Yield Shares received until the old
certificates have been surrendered. 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 HIAT III ("INDEPENDENT TRUSTEES"), AS THAT TERM IS DEFINED IN THE
1940 ACT, HAS CONCLUDED THAT THE REORGANIZATION IS IN THE BEST INTERESTS OF
HIAT III AND ITS SHAREHOLDERS AND RECOMMENDS APPROVAL OF THE REORGANIZATION
AGREEMENT.


FEE TABLE


     The following table briefly describes the fees and expenses that a
shareholder of HIAT III and a Class D shareholder of High Yield may pay if they
buy and hold shares of each respective fund. HIAT III and High Yield each pay a
variety of expenses for management of their assets, distribution of their
shares (High Yield) and other services, and those expenses are reflected in the
net asset value per share of each fund. Class D shares of High Yield do not pay
distribution-related fees; however, the other three Classes offered by High
Yield pay fees for the distribution of their shares. These expenses are
deducted from each respective fund's assets and are based on expenses paid by
HIAT III for its fiscal year ended January 31, 2002 and on expenses paid by
Class D shares of High Yield for its fiscal year ended August 31, 2001. The
table also sets forth pro forma fees for the surviving combined fund (High
Yield) reflecting what the fee schedule would have been on August 31, 2002, if
the Reorganization had been consummated twelve (12) months prior to that date
and assuming Class D fees and expenses.

- ----------
(1)   Purchases and sales of HIAT III are made on the New York Stock Exchange
      or otherwise through brokers and dealers and are generally subject to
      brokerage commissions which vary. Customarily, such commissions may
      depend upon the size of the transaction, the broker selected and other
      factors.




EXAMPLE

     To attempt to show the effect of these expenses on an investment over
time, the hypotheticals shown below have been created. The Example assumes that
an investor invests $10,000 in either HIAT III or Class D shares of High Yield
or the new combined fund (High Yield), that the investment has a 5% return each
year and that the operating expenses for each fund remain the same (as set
forth in the chart above). Although a shareholder's actual costs may be higher
or lower, the tables below show a shareholder's costs at the end of each period
based on these assumptions.

     Expenses Over Time:







                                                      1 YEAR     3 YEARS     5 YEARS     10 YEARS
                                                     --------   ---------   ---------   ---------
                                                                            
HIAT III .........................................     $182        $563        $970      $2,105
HIGH YIELD (CLASS D) .............................     $ 83        $259        $450      $1,002
PRO FORMA COMBINED-HIGH YIELD (CLASS D) ..........     $ 83        $259        $450      $1,002



     The purpose of the foregoing fee table is to assist the investor or
shareholder in understanding the various costs and expenses that an investor or
shareholder in the fund will bear directly or indirectly. For a more


                                       5


complete description of these costs and expenses, see "Comparison of HIAT III
and High Yield -- Investment Management and Administration Fees, Other
Significant Fees, and Purchases, Exchanges and Redemptions" below.


TAX CONSEQUENCES OF THE REORGANIZATION

     As a condition to the Reorganization, HIAT III and High Yield, will
receive an opinion of Mayer, Brown. Rowe & Maw 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 HIAT III or the
shareholders of HIAT III 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.


REASONS FOR THE REORGANIZATION

     The Board of Trustees has determined that the Reorganization is in the
best interests of HIAT III shareholders. In particular, the Reorganization
would afford HIAT III shareholders the opportunity for a continued interest in
a fund which has investment objectives similar to that of HIAT III, and which
is substantially larger and has a significantly lower expense ratio than HIAT
III. The Board of Trustees believes that other potential benefits could be
realized as well. For further information on the reasons for the Board's
decision, see "The Reorganization -- The Board's Consideration," set forth
below.


COMPARISON OF HIAT III AND HIGH YIELD

     INVESTMENT OBJECTIVES AND POLICIES. HIAT III and High Yield have similar
investment objectives. As their primary investment objective, HIAT III and High
Yield seek to earn a high level of current income. As their secondary
investment objective, HIAT III and High Yield seek capital appreciation but
only when consistent with their primary investment objective. The respective
investment objectives of HIAT III and High Yield are fundamental and may not be
changed without respective shareholder approval.

     High Yield seeks to achieve its primary investment objective by investing
at least 80% of its assets in fixed-income securities rated lower than Baa by
Moody's Investors Service ("Moody's") or lower than BBB by Standard & Poor's
Corporation ("S&P") or in non-rated securities considered by the fund's
investment manager, MS Advisors, to be appropriate investments for the fund.
Securities rated below Baa or BBB are commonly known as "junk bonds." Likewise,
HIAT III seeks to achieve its primary investment objective by investing at
least 80% of its assets in such lower rated and unrated securities.

     Other than as set forth above, the investment policies of HIAT III and
High Yield are substantially similar; the principal differences between them
are described under "Comparison of Investment Objectives, Policies and
Restrictions" below.

     INVESTMENT MANAGEMENT FEES. Pursuant to an Investment Management
Agreement, HIAT III's investment manager, MS Advisors, provides administrative
services and manages HIAT III's assets, including placing orders for the
purchase and sale of portfolio securities. MS Advisors obtains and evaluates
such information and advice relating to the economy, securities markets and
securities as it deems necessary or useful to manage the assets of HIAT III in
a manner consistent with its objective and policies. As compensation for
advisory services provided to HIAT III, HIAT III pays MS Advisors monthly
compensation calculated weekly by applying the following annual rates to HIAT
III's weekly net assets: 0.75% of the portion of the average weekly assets not
exceeding $250 million; 0.60% of the portion of the average weekly assets
exceeding $250 million and not exceeding $500 million; 0.50% of the portion of
the average weekly assets exceeding $500 million and not


                                       6


exceeding $750 million; 0.40% of the portion of the average weekly assets
exceeding $750 million and not exceeding $1 billion; and 0.30% of the portion
of the average weekly assets exceeding $1 billion. The services provided to
HIAT III under the Investment Management Agreement are comparable to those
provided by MS Advisors to High Yield under its Investment Management Agreement
with MS Advisors. Pursuant to that agreement, High Yield pays MS Advisors,
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; and 0.325% of the
portion of the daily net assets exceeding $2 billion but not exceeding $3
billion; and 0.30% of the portion of the daily net assets exceeding $3 billion.
Each class of shares of High Yield is subject to the same management fee rates.



     HIAT III is a closed-end investment company and therefore does not have a
distribution plan pursuant to Rule 12b-1 under the 1940 Act ("12b-1 Plan").
High Yield has adopted a 12b-1 Plan for the distribution of its shares,
however, there are no 12b-1 fees applicable to High Yield's Class D shares. For
information relating to the 12b-1 fees applicable to High Yield's Class A, B
and C shares, see the section entitled "Share Class Arrangements" in High
Yield's Prospectus, attached hereto.


     OTHER SIGNIFICANT FEES. Both HIAT III and High Yield pay additional fees
in connection with their operations, including legal, auditing, transfer agent,
trustees fees and custodial fees, registration fees in the case of High Yield
and, in the case of HIAT III, listing fees for the listing of its shares on the
New York Stock Exchange ("NYSE"). See "Synopsis -- Fee Table" above for the
percentage of average net assets represented by such "Other Expenses."


     PURCHASES, EXCHANGES AND REDEMPTIONS. Class D shares of High Yield are
currently offered at net asset value and such shares may be redeemed for cash
without redemption or other charge at the net asset value per share next
determined. Normally, Class D shares of High Yield are offered only to a
limited group of investors. Subsequent to the Reorganization, all HIAT III
shares will be designated Class D shares of High Yield. However, additional
investments (except for reinvestment of distributions received on shares
acquired as a result of the Reorganization) in Class D shares of High Yield (or
in Class D shares of any other Morgan Stanley Fund) by Shareholders holding
such shares may only be made if those Shareholders are otherwise eligible to
purchase Class D shares. Class D shares acquired in the Reorganization may,
however, be exchanged for Class D shares of another Morgan Stanley Fund
pursuant to Class D's exchange privileges discussed below.


     High Yield offers four classes of shares (Class A, Class B, Class C and
Class D) which differ principally in terms of sales charges, distribution and
service fees, and ongoing expenses. For further information relating to each of
the classes of High Yield's shares, see the section entitled "Share Class
Arrangements" in High Yield's Prospectus attached hereto.


     Class D shares of High Yield that are held with a broker-dealer that has
entered into a selected dealer agreement with High Yield's distributor (or
shares held directly with High Yield's transfer agent) may be exchanged for
Class D shares of any other Morgan Stanley Fund that offers its shares in more
than one class, or any of Morgan Stanley Limited Duration U.S. Treasury Trust,
Morgan Stanley Limited Term Municipal Trust, Morgan Stanley Limited Duration
Fund and the five Morgan Stanley Funds that are money market funds (the
foregoing funds are collectively referred to as the "Exchange Funds"), without
the imposition of an exchange fee. Exchange privileges will not be available to
Shareholders who hold High Yield shares with broker-dealers that have not
entered into a selected dealer agreement with High Yield's distributor.


                                       7


     High Yield shareholders may redeem their High Yield shares on any business
day at the net asset value of such shares. High Yield provides telephone
exchange privileges to its shareholders. For greater details relating to
exchange privileges applicable to High Yield, see the section entitled "How to
Exchange Shares" in High Yield's Prospectus.

     High Yield may redeem involuntarily, at net asset value, most accounts
valued at less than $100. However, High Yield offers a reinstatement privilege
whereby a shareholder who has not previously exercised such privilege whose
shares have been redeemed may, within thirty-five days after the date of
redemption, reinstate any portion or all of the proceeds thereof in shares of
the same class from which such shares were redeemed.

     Unlike High Yield, HIAT III is a closed-end investment company and does
not redeem its shares or engage in the continuous offering of new shares in the
same manner as an open-end investment company and does not offer to exchange
its shares for shares of other investment companies. Shares of HIAT III are
only purchased and sold on the NYSE.

     DIVIDENDS. Both High Yield and HIAT III declare and pay dividends from net
investment income monthly. Both High Yield and HIAT III generally distribute
all of their net realized short-term and long-term capital gains at least once
per year. Each, however, may determine either to distribute or to retain all or
part of any net long-term capital gains in any year for reinvestment. With
respect to High Yield, dividends and capital gains distributions are
automatically reinvested in additional shares at net asset value unless the
shareholder elects to receive cash. All persons who become registered holders
of HIAT III are automatically included in HIAT III's automatic dividend
reinvestment plan unless they elect to receive distributions in cash. Under
that plan, Shareholders' dividends are automatically reinvested in shares of
HIAT III at the then current market price of such shares. For more information
on HIAT III's dividend reinvestment plan, see Exhibit C to this Proxy Statement
and Prospectus.


                             PRINCIPAL RISK FACTORS

     The share price or net asset value of High Yield and the market price per
share of HIAT III on the NYSE as well as HIAT III's net asset value will
fluctuate with changes in the market value of their respective portfolio
securities. The market value of the funds' portfolio securities will increase
or decrease due to a variety of economic, market and political factors,
including changes in prevailing interest rates, which cannot be predicted. The
principal risks of an investment in either High Yield or HIAT III are the risks
associated with their respective fixed-income securities which primarily
consist of high yield, high risk securities commonly known as "junk bonds."
Fixed income securities are subject to two types of risks: credit risk and
interest rate risk.

     Credit risk refers to the possibility that the issuer of a security will
be unable or unwilling to make interest payments and/or repay the principal on
its debt. Interest rate risk refers to fluctuations in the value of a
fixed-income security resulting from changes in the general level of interest
rates. When the general level of interest rates goes up, the prices of most
fixed-income securities go down. When the general level of interest rates goes
down, the prices of most fixed-income securities go up.

     Junk bonds are subject to greater risk of loss of income and principal
than higher rated securities. The prices of junk bonds are likely to be more
sensitive to adverse economic changes or individual corporate developments than
higher rated securities. During an economic downturn or substantial period of
rising interest rates, junk bond issuers and, in particular, highly leveraged
issuers may experience financial stress that would adversely affect their
ability to service their principal and interest payment obligations, to meet
their projected business goals or to obtain additional financing. In the event
of a default, the funds may incur additional expenses to seek recovery. The
secondary market for junk bonds may be less liquid than the markets for higher


                                       8


quality securities and, as such, may have an adverse effect on the market
prices of certain securities. The Rule 144A securities could have the effect of
increasing the level of fund illiquidity to the extent the funds may be unable
to find qualified institutional buyers interested in purchasing the securities.
The illiquidity of the market may also adversely affect the ability of the
funds' Directors/Trustees to arrive at a fair value for certain junk bonds at
certain times and could make it difficult for the fund to sell certain
securities. In addition, periods of economic uncertainty and change probably
would result in an increased volatility of market prices of high yield
securities and a corresponding volatility in the funds' net asset value.

     In addition to junk bonds, both High Yield and HIAT III invest up to 20%
of their assets in investment grade fixed-income securities. Some of these
securities have speculative characteristics.

     Both High Yield and HIAT III may invest up to 20% of their total assets in
common stocks. In general stock values fluctuate in response to activities
specific to the company as well as general market, economic and political
conditions. These prices can fluctuate widely.

     Each fund may invest up to 20% of its assets in foreign securities
including fixed income securities issued by foreign governments and other
foreign issuers (including American depositary receipts or other similar
securities convertible into securities of foreign issuers) but not more than
10% of its total assets in these securities may be denominated in foreign
currencies. The funds' investments in foreign securities involve risks that are
in addition to the risks associated with domestic securities. One additional
risk is currency risk. In particular, the price of securities could be
adversely affected by changes in the exchange rate between U.S. dollars and a
foreign market's local currency. Foreign securities (including depositary
receipts) also have risks related to economic and political developments
abroad, including any effects of foreign social, economic or political
instability. Foreign companies, in general, are not subject to the regulatory
requirements of U.S. companies and, as such, there may be less publicly
available information about these companies. Moreover, foreign accounting,
auditing and financial reporting standards generally are different from 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 funds to obtain or enforce a
judgment against the issuers of the 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 U.S. counterparts. In addition, differences in
clearance and settlement procedures in foreign markets may occasion delays in
settlements of the funds' trades effected in those markets.

     The funds may invest in put and call options and futures on their
portfolio securities, stock indexes and U.S. and foreign currencies. The funds
may use options and futures to protect against a decline in the funds'
securities or in currency prices or an increase in prices of securities or
currencies that may be purchased, as well as to protect against interest rate
changes. If the funds invest in options and/or futures, their participation in
these markets would subject the funds' portfolios to certain risks. If the
Investment Manager's predictions of movements in the direction of the stock or
currency markets are inaccurate, the adverse consequences to the funds (e.g., a
reduction in the funds' net asset value or a reduction in the amount of income
available for distribution) may leave the funds in a worse position than if
these strategies were not used. Other risks inherent in the use of options and
futures include, for example, the possible imperfect correlation between the
price of options and futures contracts and movements in the prices of the
securities or currencies being hedged, and the possible absence of a liquid
secondary market for any particular instrument. Certain options may be
over-the-counter options which are options negotiated with dealers; there is no
secondary market for these investments.

     The foregoing discussion is a summary of the principal risk factors of
HIAT III and High Yield. For a more complete discussion of the risks of High
Yield, see "Principal Risks" and "Additional Risk Information" in High Yield's
Prospectus attached hereto and incorporated herein by reference.

                              THE REORGANIZATION


THE BOARD'S CONSIDERATION

     At a meeting held on July 25, 2002, the Board, including all of the
Independent Trustees, unanimously approved the Reorganization Agreement and
determined to recommend that HIAT III Shareholders approve the Reorganization
Agreement. In reaching this decision, the Board made an extensive inquiry into
a number of factors, particularly the comparative expense ratios of HIAT III
and the Class D shares of High Yield, and the effect on Shareholders of
"open-ending" HIAT III including, for example, the ability to realize the net
asset value of their shares and the potential impact of redemptions on
portfolio management. The Board also considered other factors, including, but
not limited to: comparable investment objectives, policies, restrictions and
portfolios of HIAT III 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 HIAT III and High Yield in connection with the
Reorganization.

     In recommending the Reorganization to Shareholders, the Board of HIAT III
considered the following:


     1. The expense ratio for the Class D shares of High Yield (0.62% for its
fiscal year end August 31, 2001; 0.81% for its fiscal year end August 31, 2002)
is substantially lower than the expense ratio for HIAT III (1.79% for its
fiscal year end January 31, 2002; 2.25% for the twelve months ended August 31,
2002). This is partially attributable to the fact that High Yield's investment
management fee rate (0.43% of its net assets) was appreciably lower for its
fiscal year end August 31, 2001 (0.48% for its fiscal year end August 31, 2002)
than HIAT III's investment management fee rate (0.75%) paid for the twelve
months ended August 31, 2001 and August 31, 2002. Furthermore, the rate of
other expenses paid by Class D shareholders of High Yield (0.19% of average
daily net assets) for its fiscal year end August 31, 2001 (0.33% for its fiscal
year end August 31, 2002) was significantly lower than the rate of other
expenses paid by HIAT III (1.04% of average daily net assets) for the its last
fiscal year and 1.50% for the twelve months ended August 31, 2002. In addition,
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. Therefore, once the Reorganization is
consummated, the expenses which would be borne by Class D shareholders of the
"combined fund" are expected to be significantly lower on a percentage basis
than the expenses per share of HIAT III.


     2. HIAT III, has generally traded at a premium, but recently has traded at
a discount to its net asset value and is, as of the date of this Proxy
Statement and Prospectus, trading at a discount. To the extent that HIAT III is
trading at a discount on the date of the Reorganization, the Reorganization at
net asset value would benefit the Shareholders of HIAT III by immediately
eliminating any such discount.


     3. Shareholders of HIAT III would have a continued participation in a
portfolio of lower-rated and unrated fixed-income securities.

     4. HIAT III does not currently satisfy certain NYSE listing standards.
Therefore, absent the Reorganization, there is a risk that the shares could
become ineligible for trading on the NYSE.

     5. Shareholders would have the ability to exchange their Class D shares of
High Yield acquired as a result of the Reorganization into Class D shares of
any Morgan Stanley Multi-Class Fund without the imposition of any sales charge
or additional fees. The Board noted, however, that exchange privileges will not
be available to Shareholders who hold High Yield shares with broker-dealers
that have not entered into a selected dealer agreement with High Yield's
distributor. HIAT III, being a closed-end fund, does not offer any exchange
privileges.



                                       10



     6. The Reorganization is intended to qualify as a tax-free reorganization
for federal income tax purposes, pursuant to which no gain or loss will be
recognized by HIAT III or its Shareholders for Federal income tax purposes as a
result of transactions included in the Reorganization.

     7. The Board recognized that if at the time of the Reorganization, HIAT
III is trading at a premium to its net asset value, HIAT III shareholders would
receive High Yield shares with a value less than the amount which could have
been realized through a sale of shares in the open market and no material
adjustments in High Yield's portfolio will be necessary to accommodate the
Reorganization. See "Additional Matters Regarding HIAT III -- History of Public
Trading of HIAT III's Shares" below. The Board concluded, however, that the
potential benefits of the Reorganization outweighed the potential risk of the
elimination of any premium at which the shares trade on the date of the
Reorganization.


     The Board of Directors of High Yield, including a majority of the
Independent Directors 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 costs attendant to the purchase of such securities in
the market. Also, the addition of HIAT III's assets to High Yield's portfolio
may result in a further reduction in High Yield's investment management fee
resulting from the addition of more assets at a lower breakpoint rate in the
management fee schedule and may result also in the economies of scale described
above. The Board also considered any potential liabilities associated with the
pending litigation against HIAT III. See "Additional Information About HIAT III
and High Yield -- Litigation." The Board noted in this regard that in
connection with the Reorganization, the Investment Manager has agreed to
indemnify High Yield against any and all claims, costs and expenses associated
with the HIAT III litigation. Finally, the Board considered that even if the
benefits enumerated above are not realized, the costs to the Fund are
sufficiently minor to warrant taking the opportunity to realize those benefits.



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) HIAT III will transfer all
of its assets, including portfolio securities, cash (other than cash amounts
retained by HIAT III 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
stated liabilities of HIAT III, including all expenses, costs, charges and
reserves, as reflected on an unaudited statement of assets and liabilities of
HIAT III prepared by the Treasurer of HIAT III, 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 the
High Yield Shares; (ii) such High Yield Shares would be distributed to
Shareholders on the Closing Date or as soon as practicable thereafter; (iii)
HIAT III would be de-registered as an investment company under the 1940 Act;
(iv) HIAT III would be dissolved as a Massachusetts business trust; and (v) the
outstanding shares of HIAT III would be canceled.

     The number of High Yield Shares to be delivered to HIAT III will be
determined by dividing the aggregate net asset value of the shares of HIAT III
acquired by High Yield by the net asset value per share of the Class D shares
of High Yield; these values will be calculated as of the close of business of
the New York Stock Exchange on the third business day following the receipt of
the requisite approval by Shareholders of the Reorganization Agreement or at
such other time as HIAT III and High Yield may agree (the "Valuation


                                       11



Date"). As an illustration, assume that on the Valuation Date, the shares of
HIAT III had an aggregate net asset value (not including any Cash Reserve of
HIAT III) of $100,000. If the net asset value per Class D share of High Yield
were $10 per share at the close of business on the Valuation Date, the number of
Class D shares of High Yield to be issued would be 10,000 ($100,000 (divided by)
$10). These 10,000 Class D shares of High Yield would be distributed to the
former shareholders of HIAT III. 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, HIAT III 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. Each Shareholder will
receive Class D shares of High Yield that corresponds to the shares of HIAT III
currently held by that Shareholder. 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 only upon
written request of a Shareholder and only for whole shares, with fractional
shares credited to the name of the Shareholder on the books of High Yield.
Shareholders who wish to receive certificates representing their High Yield
Shares must, after receipt of their confirmations, make a written request to
High Yield's transfer agent Morgan Stanley Trust, Harborside Financial Center,
Jersey City, New Jersey 07311. Shareholders of HIAT III holding their shares in
certificate form will be asked to surrender such certificates in connection
with the Reorganization. Shareholders who do not surrender their certificates
prior to the Closing Date will still receive their shares of High Yield;
however, such Shareholders will not be able to redeem, transfer or exchange the
High Yield Shares received until the old certificates have been surrendered.


     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 and the receipt of the other agreements,
opinions and certificates set forth in Sections 6, 7 and 8 of the
Reorganization Agreement (attached hereto as Exhibit A) and the occurrence of
the events described in those Sections, certain of which may be waived by HIAT
III or High Yield. The Reorganization Agreement may be amended in any mutually
agreeable manner. All expenses of this solicitation, including the cost of
preparing and mailing this Proxy Statement and Prospectus, will be borne, as
set forth in this Proxy Statement and Prospectus under "Expenses of
Solicitation," by HIAT III, which expenses are expected to approximate
$100,000. HIAT III and High Yield will bear all of their respective other
expenses associated with the Reorganization.


     The Reorganization Agreement may be terminated and the Reorganization
abandoned at any time, before or after approval by Shareholders or by mutual
consent of HIAT III, 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 March 31, 2003, 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, HIAT III 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 HIAT III that received High Yield
Shares. HIAT III shall be de-registered as an investment company under the 1940
Act, dissolved under Massachusetts law promptly following the distributions of
shares of High Yield to Shareholders of record of HIAT III.

     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 HIAT III (at net asset value on the Valuation Date calculated after
subtracting any 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 HIAT III recognizes net


                                       12


gain from the sale of securities prior to the Closing Date, such gain, to the
extent not offset by capital loss carryforwards, will be distributed to
Shareholders prior to the Closing Date and will be taxable to Shareholders as
capital gain.

     Prior to the NYSE's suspension of trading of HIAT III's shares, which is
currently expected to occur on the next business day after the Meeting
(assuming Shareholders of HIAT III approve the Reorganization Agreement at the
Meeting), Shareholders will continue to be able to sell their shares of HIAT
III on the NYSE at the market price of the shares on the NYSE when the sell
order is placed. Following the suspension of trading, Shareholders will no
longer be able to sell their HIAT III shares on the NYSE. On or after the
Closing Date, however, Shareholders will be able to redeem their newly-issued
shares of High Yield.


TAX ASPECTS OF THE REORGANIZATION

     At least one but not more than 20 business days prior to the Valuation
Date, HIAT III 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 HIAT III's investment company taxable income for all
periods since the inception of HIAT III through and including the Valuation
Date (computed without regard to any dividends paid deduction), and all of HIAT
III's net capital gain, if any, realized in such periods (after reduction for
any capital loss carryforward).

     The Reorganization is intended to qualify for Federal income tax purposes
as a tax-free reorganization under Section 368(a)(1)(C) of the Internal Revenue
Code of 1986, as amended (the "Code").


     As a condition to the Reorganization, HIAT III and High Yield will receive
an opinion of Mayer, Brown, Rowe & Maw to the effect that, based on certain
assumptions, facts, the terms of the Reorganization Agreement and
representations set forth in the Reorganization Agreement or otherwise provided
by HIAT III and High Yield (including a representation to the effect that High
Yield has no plan or intention to sell or otherwise dispose of more than 66% of
the assets of HIAT III acquired in the Reorganization except for dispositions
made in the ordinary course of business):


     1. The transfer of HIAT III's assets in exchange for the High Yield Shares
and the assumption by High Yield of certain stated liabilities of HIAT III
followed by the distribution by HIAT III of the High Yield Shares to
Shareholders in exchange for their HIAT III shares pursuant to and in
accordance with the terms of the Reorganization Agreement will constitute a
"reorganization" within the meaning of Section 368(a)(1)(C) of the Code, and
HIAT III 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 HIAT III solely in exchange for the High Yield Shares and the
assumption by High Yield of the stated liabilities of HIAT III;

     3. No gain or loss will be recognized by HIAT III upon the transfer of the
assets of HIAT III 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 HIAT III shares;

     4. No gain or loss will be recognized by Shareholders upon the exchange of
the shares of HIAT III 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 HIAT III held by each such Shareholder
immediately prior to the Reorganization;


                                       13


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

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

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

     The advice of Counsel is not binding on the Internal Revenue Service or
the courts and neither HIAT III nor High Yield has sought or will seek a ruling
with respect to the tax treatment of the Reorganization.

     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.


TAX CONSEQUENCES OF THE REORGANIZATION TO HIAT III AND HIGH YIELD.

     Under the Code, the Reorganization may result in limitations on the
utilization of the capital loss carryovers and built-in losses of HIAT III. The
effect of any such limitations will depend on the existence and amount of HIAT
III's capital loss carryovers and built-in losses at the time of the
Reorganization. A fund will have built-in losses in its assets if its tax basis
in its assets exceeds the fair market value of such assets on the date of the
Reorganization. While the actual amount of such limitation will be determined
at the time of the Reorganization, if, for example, the Reorganization had
occurred on July 19, 2002, each year only approximately $0.7 million of HIAT
III's capital loss carryovers and recognized built-in capital losses would have
been able to be used to offset capital gains of the Combined Fund. The
Reorganization should not have any effect on the capital loss carryovers and
built-in losses of High Yield.


DESCRIPTION OF SHARES OF HIGH YIELD AND HIAT III AND THE ORGANIZATION OF THE
   TWO FUNDS

     Class D 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 stated
above, Class D shares of High Yield are not subject to any sales charge on
purchase or redemption or any 12b-1 fee.

     Shares of HIAT III (the only existing class of which is common) are
entitled to one vote for each share held and to vote for the election of
Trustees and on other matters submitted to meetings of shareholders. Shares of
HIAT III have no pre-emptive or conversion rights and the shares, when issued,
are fully paid and non-assessable.

     The shareholders of High Yield are entitled to a full vote for each full
common share held. High Yield is authorized to issue an unlimited number of
common shares. All common shares of High Yield are 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, Class A, Class B and Class C bear
expenses related to the distribution of their respective shares.


                                       14


     High Yield's Articles of Incorporation permits the Directors 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. The Directors have not presently authorized any
such additional series or Classes of shares other than as set forth in High
Yield's Prospectus.

     High Yield is not required to hold annual meetings of shareholders and in
ordinary circumstances High Yield does not intend to hold such meetings. The
Directors may call special meetings of shareholders for action by shareholder
vote as may be required by the Investment Company Act or the Articles of
Incorporation. Under certain circumstances, the Directors may be removed by the
actions of the Directors. In addition, under certain circumstances, the
shareholders may call a meeting to remove the Directors and High Yield is
required to provide assistance in communicating with shareholders about such a
meeting. 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
Directors being selected, while the holders of the remaining shares would be
unable to elect any Directors. HIAT III, whose shares are listed on the NYSE,
does hold annual meetings as required by the rules of the NYSE.

     HIAT III is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of a business trust may,
under certain limited circumstances, be held personally liable as partners for
the obligations of HIAT III. However, the Declaration of Trust contains an
express disclaimer of shareholder liability for acts or obligations of HIAT
III, requires that notice of such HIAT III obligations include such disclaimer,
and provides for indemnification out of the HIAT III's property for any
shareholder held personally liable for the obligations of HIAT III. Thus, the
risk of a shareholder incurring financial loss on account of shareholder
liability is limited to circumstances in which HIAT III itself would be unable
to meet its obligations. High Yield is a Maryland corporation. Shareholders of
a Maryland Corporation are not personally liable for the obligations of the
company.

     HIAT III presently has certain anti-takeover provisions in its Declaration
of Trust which could have the effect of limiting the ability of other entities
or persons to acquire control of HIAT III, to cause it to engage in certain
transactions or to modify its structure. The Board of Trustees is divided into
three classes, each having a term of three years. Each year the term of one
class expires. This provision could delay for up to two years the replacement
of a majority of the Board of Trustees. In addition, the affirmative vote or
consent of the holders of 80% of the shares of HIAT III (a greater vote than
that required by the 1940 Act and greater than the required vote applicable to
business corporations under state law) is required to authorize the conversion
of HIAT III from a closed-end to an open-end investment company, or generally
to authorize any of the following transactions:

     (i)    merger or consolidation of HIAT III with or into any other
            corporation;

     (ii)   issuance of any securities of HIAT III to any person or entity for
            cash;

     (iii)  sale, lease or exchange of all or any substantial part of the assets
            of HIAT III, to any entity or person (except assets having an
            aggregate fair market value of less than $1,000,000);

     (iv)   sale, lease or exchange to HIAT III, in exchange for securities of
            HIAT III, of any assets of any entity or person (except assets
            having an aggregate fair market value of less than $1,000,000)

if such corporation, person or entity is directly, or indirectly through
affiliates, the beneficial owner of 5% or more of the outstanding shares of
HIAT III. However, such 80% vote or consent will not be required with respect
to the foregoing transactions where the Board of Trustees under certain
conditions approves the transaction (as the Board has done with respect to the
Reorganization), in which case, with respect to (i) and


                                       15


(iii) above, a majority shareholder vote or consent will be required, and, with
respect to (ii) and (iv) above, no shareholder vote or consent would be
required. Furthermore, any amendment to the provisions in the Declaration of
Trust requiring an 80% shareholder vote or consent for the foregoing
transactions similarly requires an 80% shareholder vote or consent.

        COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS

INVESTMENT OBJECTIVES AND POLICIES

     HIAT III and High Yield have similar investment objectives. Both HIAT III
and High Yield, as a primary investment objective, seek to earn a high level
current income. As a secondary investment objective, HIAT III and High Yield
seek capital appreciation but only to the extent consistent with their primary
objective.

     High Yield invests at least 80% of its assets in fixed-income securities
rated lower than Baa by Moody's or lower than BBB by S&P (commonly known as
"junk bonds") or in non-rated securities considered by MS Advisors to be
appropriate investments for the fund. These lower-rated and unrated fixed
income securities may also include "Rule 144A" securities, which are subject to
resale restrictions. There are no minimum quality ratings for investments, and
as such the fund may invest in securities which no longer make payments of
interest or principal. In deciding which securities to buy, hold or sell, MS
Advisors considers an issuer's creditworthiness, economic developments,
interest rate trends and other factors it deems relevant. In evaluating an
issuer's creditworthiness, MS Advisors relies principally on its own analysis.
A security's credit rating is simply one factor that may be considered by MS
Advisors in this regard. High Yield may invest up to 20% of its assets in


                                       16


securities rated Baa or BBB or higher (or, if not rated, determined to be of
comparable quality) when MS Advisors believes that such securities may produce
attractive yields. The fund's fixed-income securities may include zero coupon
securities and payment in kind bonds. Zero coupon securities are purchased at a
discount and either (i) pay no interest, or (ii) accrue interest, but make no
payments until maturity; payment in kind bonds are purchased at the face amount
of the bond and accrue additional principal but make no payments until
maturity. High Yield may also invest in common stocks and foreign securities,
and, may acquire warrants which may or may not be attached to common stock and
may purchase units which combine debt securities with equity securities.
Additionally, High Yield may invest up to 10% of its assets in municipal
obligations that pay interest exempt from federal income tax. Other than its
investment objectives, the foregoing investment policies of High Yield may be
changed without shareholder approval.


     HIAT III also invests at least 80% of its assets in the lower-rated and
unrated fixed-income securities previously described, as well as Rule 144A
securities. Fixed-income securities appropriate for HIAT III and High Yield may
include both convertible and nonconvertible debt securities and preferred
stock. Under normal conditions, 20% of HIAT III's total assets may be invested
in higher-rated fixed-income securities and unrated fixed-income securities of
comparable quality and HIAT III also may invest up to 10% of its assets in
municipal obligations. HIAT III may also purchase common stocks, foreign
securities, money market instruments and may acquire warrants and unit
offerings.


     Both High Yield and HIAT III may take temporary "defensive" positions that
are inconsistent with each fund's principal investment strategies in attempting
to respond to adverse market conditions. Both High Yield and HIAT III may
invest any amount of their assets in cash or money market instruments in a
defensive posture when MS Advisors believes it is advisable to do so.


     Other than its investment objectives, the foregoing investment policies of
HIAT III may be changed without shareholder approval.


     Both High Yield and HIAT III may (i) engage in options and futures
transactions, (ii) purchase securities on a when-issued or delayed delivery
basis, (iii) purchase securities on a "when, as and if issued" basis, (iv)
enter into repurchase agreements, (HIAT III may not invest in repurchase
agreements that do not mature within seven days, if any such investments amount
to more than 10% of HIAT III's total assets), (v) invest in private placements
(up to 15% in the case of High Yield and up to 10% in the case of HIAT III),
(vi) lend their portfolio securities (up to 25% in the case of High Yield and
up to 10% in the case of HIAT III), and (vii) invest in public utilities.


     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 High Yield's policies, see "Principal Investment Strategies" and
"Additional Investment Strategy Information" in High Yield's Prospectus and
"Description of the Fund and Its Investments and Risks" in High Yield's
Statement of Additional Information.


INVESTMENT RESTRICTIONS


     The investment restrictions adopted by HIAT III and High Yield as
fundamental policies are substantially similar. HIAT III's investment
restrictions and their similarities or differences with High Yield's investment
restrictions are summarized below. A full description of High Yield's
investment restrictions can be found under the caption "Description of the Fund
and Its Investments and Risks -- Fund Policies/Investment Restrictions" in High
Yield's Statement of Additional Information. A fundamental investment
restriction cannot be changed without the vote of the majority of the
outstanding voting securities of a fund, as defined in the 1940 Act.


                                       17


     HIAT III may not:

     1. Acquire common stocks in excess of 20% of its total assets. High Yield
has a similar restriction.

     2. As to 75% of its total assets, invest more than 5% 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).
High Yield has a similar restriction but as to 100% of its total assets.

     3. As to 75% of its total assets, 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. High Yield has a similar restriction but as to 100% of its total
assets.

     4. Invest 25% or more 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. High Yield has an
identical restriction.

     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. High Yield has an
identical restriction.

     6. Invest more than 10% of its total assets in securities which are
restricted as to disposition under the federal securities laws or otherwise.
This restriction shall not apply to securities received as a result of
corporate reorganization or similar transaction affecting readily marketable
securities already held in HIAT III's portfolio; however, HIAT III will attempt
to dispose in an orderly fashion of any securities received under these
circumstances to the extent that such securities exceed 15% of HIAT III's total
assets. High Yield, as an open-end investment company, may not invest more than
15% of its assets in illiquid securities.

     7. Invest in securities of any issuer if, to the knowledge of the fund,
any officer or trustee of the fund or any officer or director of the Investment
Manager owns more than 1/2 of 1% of the outstanding securities of such issuer,
and such officers, trustees and directors who own more than 1/2 of 1% own in
the aggregate more than 5% of the outstanding securities of such issuer. High
Yield has an identical restriction.

     8. 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. High Yield
has an identical restriction.

     9. Purchase or sell commodities except that the fund may purchase or sell
financial futures contracts and related options. High Yield has an identical
restriction.

     10. Purchase oil, gas or other mineral leases, rights or royalty
contracts, or exploration or development programs, except that the fund may
invest in securities of companies which invest in or sponsor such programs.
High Yield has an identical restriction.

     11. Write, purchase or sell puts, calls, or combinations thereof, except
for options on futures contracts or options on debt securities. High Yield has
an identical restriction.

     12. Purchase securities of other investment companies, except in
connection with a merger, consolidation, reorganization or acquisition of
assets. High Yield has an identical restriction.

     13. Borrow money, except that the fund may borrow from a bank for
temporary or emergency purposes or for repurchase of its shares provided that
immediately after such borrowing the amount borrowed does not


                                       18


exceed 33 1/3% of the value of its total assets (including the amount borrowed)
less its liabilities (not including any borrowings but including the fair
market value at the time of computation of any other senior securities which
are outstanding at the time). High Yield may only borrow for temporary purposes
and only in amounts not exceeding 5% of the value of its total assets (not
including the amount borrowed).

     14. Pledge its assets or assign or otherwise encumber them except to
secure borrowings effected within the limitations set forth in Restriction 13.
However, 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. High Yield
has a substantially similar restriction.

     15. Issue senior securities as defined in the 1940 Act, except insofar as
the fund may be deemed to have issued a senior security by reason of: (a)
entering into any repurchase agreement; (b) purchasing any securities on a
when-issued or delayed delivery basis; (c) purchasing or selling any financial
futures contracts; (d) borrowing money in accordance with restrictions
described above; or (e) lending portfolio securities. High Yield is similarly
restricted.

     16. Make loans of money or securities, except: (a) by the purchase of 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. High Yield has an identical restriction.

     17. Make short sales of securities. High Yield has an identical
restriction.

     18. Purchase securities on margin, except for such short-term loans as are
necessary for the clearance of purchases of portfolio securities. High Yield
has an identical restriction.

     19. 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. High Yield has an identical restriction.

     20. Invest for the purpose of exercising control or management of another
company. High Yield has an identical restriction.

             ADDITIONAL INFORMATION ABOUT HIAT III AND HIGH YIELD


GENERAL

     HIAT III was organized as a "Massachusetts business trust" under the laws
of the Commonwealth of Massachusetts on November 23, 1988 and commenced
operations as a closed-end registered investment company on February 28, 1989.
For a discussion of the organization and operation of High Yield, see "Fund
Management" and "Investment Objective" in High Yield's Prospectus.

     The Board of Trustees of HIAT III and the Board of Directors of High Yield
oversee the management of the funds but do not themselves manage the funds. The
Trustees/Directors review various services provided by or under the direction
of the Investment Manager to ensure that the funds' general investment policies
and programs are properly carried out. The Trustees/Directors also conduct
their review to ensure that administrative services are provided to the funds
in a satisfactory manner.

     Under state law, the duties of the Trustees/Directors are generally
characterized as a duty of loyalty and a duty of care. The duty of loyalty
requires a Trustee/Director to exercise his or her powers in the interest of
each fund and not the Trustee's/Director's own interest or the interest of
another person or organization. A Trustee/Director satisfies his or her duty of
care by acting in good faith with the care of an ordinarily prudent person and
in a manner the Trustee/Director reasonably believes to be in the best interest
of each fund and its shareholders.


LITIGATION

     Last year, a purported class action lawsuit was filed against HIAT III and
its Investment Manager, among others, in the District Court for the Southern
District of New York alleging that HIAT III violated the federal securities
laws and New York common law by investing more than 25% of its assets in a
single industry or group of industries -- specifically, telecommunications --
without first obtaining shareholder approval. The amended class action
complaint alleges that HIAT III's decline in its net asset value during the
period August 1998


                                       21


through August 2001 was caused by HIAT III overconcentrating its assets in the
telecommunications industry or industries, and further, that HIAT III was not
allowed to concentrate more than 25% of its assets in this single industry or
group of industries under the its Registration Statement and federal securities
laws without first obtaining shareholder approval.

     HIAT III and its Investment Manager have filed a motion to dismiss the
amended class action complaint and intend to vigorously defend the allegations
against it. The motion to dismiss is fully briefed and HIAT III is awaiting the
Court's decision on the motion. In order to ensure that High Yield is not,
subsequent to the Merger, adversely affected by the HIAT III litigation, the
Investment Manager has agreed to indemnify High Yield against any and all
claims, costs and expenses associated with the HIAT III litigation.

                                                                      EXHIBIT A


                      AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is made as of this
25th day of July, 2002, by and between MORGAN STANLEY HIGH YIELD SECURITIES
INC., a Maryland corporation ("High Yield") and MORGAN STANLEY HIGH INCOME
ADVANTAGE TRUST III, a Massachusetts business trust ("HIAT III").

     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 HIAT III in
exchange for the assumption by High Yield of all stated liabilities of HIAT III
and the issuance by High Yield of Class D shares of beneficial interest, par
value $0.01 per share (the "High Yield Shares"), to be distributed, after the
Closing Date hereinafter referred to, to the shareholders of HIAT III in
liquidation of HIAT III 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 HIAT III

     1.1 Subject to the terms and conditions herein set forth and on the basis
of the representations and warranties contained herein, HIAT III agrees to
assign, deliver and otherwise transfer the HIAT III Assets (as defined in
paragraph 1.2) to High Yield and High Yield agrees in exchange therefor to
assume all of HIAT III stated liabilities on the Closing Date as set forth in
paragraph 1.3(a) and to deliver to HIAT III the number of High Yield Shares,
including fractional High Yield Shares, determined in the manner set forth in
paragraph 2.3. Such transactions shall take place at the closing provided for
in paragraph 3.1 ("Closing").

     1.2 (a) The "HIAT III 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 HIAT III, and any deferred or prepaid expenses shown as an
asset on HIAT III's books on the Valuation Date.

     (b) On or prior to the Valuation Date, HIAT III will provide High Yield
with a list of all of HIAT III 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. HIAT III 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 HIAT III 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 HIAT
III holds any investments that High Yield is not permitted to hold, HIAT III
will dispose of such securities on or prior to the Valuation Date. In addition,
if it is determined that the portfolios of HIAT III and High Yield, when
aggregated, would contain investments exceeding certain percentage limitations
imposed upon High Yield with respect to such investments, HIAT III 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).


                                      A-1


     1.3 (a) HIAT III 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 HIAT III prepared by the Treasurer of HIAT III, as of the
Valuation Date in accordance with generally accepted accounting principles
consistently applied from the prior audited period.

     (b) On the Valuation Date, HIAT III may establish a cash reserve, which
shall not exceed 5% of HIAT III's net assets as of the close of business on the
Valuation Date ("Cash Reserve") to be retained by HIAT III 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 HIAT III 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, HIAT III 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, HIAT III
will distribute High Yield Shares received by HIAT III pursuant to paragraph
1.1 pro rata to its shareholders of record determined as of the close of
business on the Valuation Date ("HIAT III Shareholders"). Each HIAT III
Shareholder will receive Class D shares of High Yield. Such distribution will
be accomplished by an instruction, signed by the Secretary of HIAT III, to
transfer High Yield Shares then credited to HIAT III's account on the books of
High Yield to open accounts on the books of High Yield in the names of the HIAT
III Shareholders and representing the respective pro rata number of High Yield
Shares due such HIAT III Shareholders. All issued and outstanding shares of
HIAT III simultaneously will be canceled on HIAT III's books; however, share
certificates representing interests in HIAT III 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 HIAT III
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 HIAT III'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.

     1.8 Any reporting responsibility of HIAT III is and shall remain the
responsibility of HIAT III up to and including the date on which HIAT III is
dissolved pursuant to paragraph 1.9.

     1.9 Within one year after the Closing Date, HIAT III shall pay or make
provision for the payment of all its liabilities and taxes, and distribute to
the shareholders of HIAT III 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). If and to the extent that any trust, escrow
account, or other similar entity continues after the close of such one-year
period in connection either with making provision for payment of liabilities or
taxes or with distributions to shareholders of HIAT III, such entity shall
either (i) qualify as a liquidating trust under Section 7701 of the Code (and
applicable Treasury Regulations thereunder) or other entity which does not
constitute a continuation of HIAT III for federal income tax purposes, or (ii)
be subject to a waiver under


                                      A-2


Section 368(a)(2)(G)(ii) of the complete distribution requirement of Section
368(a)(2)(G)(i) of the Code. HIAT III shall be dissolved under Massachusetts
law, promptly following the making of all distributions pursuant to paragraph
1.5 (and, in any event, within one year after the Closing Date).

     1.10 Copies of all books and records maintained on behalf of HIAT III in
connection with its obligations under the Investment Company Act of 1940, as
amended (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 HIAT III is
subject under the 1940 Act.


2. VALUATION

     2.1 The value of the HIAT III Assets shall be the value of such assets
computed as of 4:00 p.m. on the New York Stock Exchange on the third business
day following the receipt of the requisite approval by shareholders of HIAT III
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 HIAT III's initial registration statement on Form N-2 dated June 17,
1987 which procedures are similar to the valuation procedures 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, with respect to each class, by
dividing the aggregate net asset value of HIAT III shares (determined in
accordance with paragraph 2.1) by the net asset value per share of Class D
shares of High Yield (determined in accordance with paragraph 2.2). For
purposes of this paragraph, the aggregate net asset value of the shares of HIAT
III shall not include the amount of the Cash Reserve.

     2.4 All computations of value shall be made by Morgan Stanley Services
Company Inc. ("MS Services") in accordance with its regular practice in pricing
High Yield. High Yield shall cause MS 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 on December 16, 2002, or at such other time as the parties may
agree. The Closing shall be held at 1221 Avenue of the Americas, New York, New
York, at the principal offices of HIAT III and High Yield. 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 HIAT III 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 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 HIAT III 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


                                      A-3


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 Morgan Stanley
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 HIAT III, accurate
appraisal of the value of the net assets of High Yield or the HIAT III 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, HIAT III shall deliver to High Yield or its designee (a)
at the Closing, a list, certified by its Secretary, of the names, addresses and
taxpayer identification numbers of the HIAT III Shareholders and the number and
percentage ownership of outstanding HIAT III shares owned by each such HIAT III
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 HIAT
III 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 HIAT III or provide evidence satisfactory to
HIAT III that such High Yield Shares have been credited to HIAT III'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.

   has been asserted with respect to any such return;

     (l) For each taxable year since its inception, HIAT III, has met all the
   requirements of Subchapter M of the Code for qualification and treatment as
   a "regulated investment company" and neither the execution or delivery of

   adversely affect the ability of HIAT III to continue to meet the
   requirements of Subchapter M of the Code;

     (m) At the Closing Date, HIAT III will have good and valid title to the

   statement of a material fact or omit to state a material fact required to
   be stated therein or necessary to make the statements therein not
   misleading. Any other information furnished by HIAT III for use in the
   Registration Statement or in any other manner that may be necessary in
   connection with the transactions contemplated hereby shall be accurate and
   complete and shall comply in all material respects with applicable Federal
   securities and other laws and regulations thereunder;

     (o) HIAT III will, on or prior to the Valuation Date, declare one or more
   dividends or other distributions to shareholders that, together with all
   previous dividends and other distributions to shareholders, shall have the

7. CONDITIONS PRECEDENT TO OBLIGATIONS OF HIGH YIELD

     The obligations of High Yield to complete the transactions provided for
herein shall be subject, at its election, to the performance by HIAT III of all
the obligations to be performed by it hereunder on or before the Closing Date
and, in addition thereto, the following conditions:

     7.1 All representations and warranties of HIAT III contained in this

made on and as of the Closing Date;

     7.2 HIAT III shall have delivered to High Yield at the Closing a
certificate of its President and its Treasurer, in form and substance
satisfactory to High Yield and dated as of the Closing Date, to the effect that

     7.4 HIAT III shall have delivered to High Yield within three business days

the taxable year ended January 31, 2000, and a letter from Deloitte & Touche
for the taxable years ended January 31, 2001 and 2002, each dated as of the
Closing Date stating that such respective firm has performed a limited review
of the Federal and state income tax returns of HIAT III for each of the
respective taxable years and, based on such limited review, nothing came to
their attention that caused them to believe that such returns did not properly
reflect, in all material respects, the Federal and state income tax liabilities
of HIAT III for the periods covered thereby; (b) a letter from Deloitte &
Touche LLP dated as of the date of the Closing Date stating that for the period
from January 31, 2002 to and including the Closing Date, Deloitte & Touche LLP
has performed a limited review (based on unaudited financial data) to ascertain
the amount of applicable Federal, state and local taxes and has determined that
same either have been paid or reserves have been established for payment of
such taxes, and, based on such limited review, nothing came to their attention
that caused them to believe that the taxes paid or reserves set aside for
payment of such taxes were not adequate in all material respects for the
satisfaction of all Federal,


                                      A-10


state and local tax liabilities for the period from January 31, 2002 to and

Mayer, Brown, Rowe & Maw, counsel to HIAT III, dated as of the Closing Date to

   management investment company under the 1940 Act, and its registration with
   the Commission as an investment company under the 1940 Act is in full force
   and effect; (c) this Agreement has been duly authorized, executed and
   delivered by HIAT III and, assuming that the Registration Statement
   complies with the 1933 Act, the 1934 Act and the 1940 Act and the
   regulations thereunder and assuming due authorization, execution and
   delivery of this Agreement by High Yield, is a valid and binding obligation

   subject as to enforcement, to bankruptcy, insolvency, reorganization,
   moratorium and other laws relating to or affecting creditors rights and to
   general equity principles; (d) the execution and delivery of this Agreement
   did not, and the consummation of the transactions contemplated hereby will
   not, violate HIAT III's Declaration of Trust or By-Laws (Massachusetts
   counsel may be relied upon in delivering such opinion); 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 consummation by HIAT III of the transactions contemplated
   herein, except such as have been obtained under the 1933 Act, the 1934 Act
   and the 1940 Act and such as may be required under state securities laws;
   and

     7.6 High Yield shall receive from the Investment Manager an agreement to
indemnify High Yield against any losses, claims and expenses associated with
the litigation that has been initiated against HIAT III in a form reasonably
satisfactory to High Yield.

     7.7 On the Closing Date, the HIAT III Assets shall include no assets that

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

The Fund

[ICON]  INVESTMENT OBJECTIVES
- --------------------------------------------------------------------------------
Morgan Stanley High Yield Securities Inc. seeks as a primary investment
objective to earn a high level of current income. As a secondary objective, the
Fund seeks capital appreciation but only to the extent consistent with its
primary objective.

[ICON]  PRINCIPAL INVESTMENT STRATEGIES
- --------------------------------------------------------------------------------

[Sidebar]
INCOME
An investment objective having the goal of selecting securities to pay out
income rather than rise in price.
[End Sidebar]

The Fund will normally invest at least 80% of its assets in fixed-income
securities (including zero coupon securities) rated below Baa by Moody's
Investors Service ("Moody's") or below BBB by Standard & Poor's Corporation
("S&P") or in non-rated securities considered by the Fund's Investment Manager
to be appropriate investments for the Fund. Such securities may also include
"Rule 144A" securities, which are subject to resale restrictions. Shareholders
of the Fund will receive at least 60 days prior notice of any changes in this
policy. Securities rated below Baa or BBB are commonly known as "junk bonds."
There are no minimum quality ratings for investments, and as such the Fund may
invest in securities which no longer make payments of interest or principal.

In deciding which securities to buy, hold or sell, the Investment Manager
considers an issuer's creditworthiness, economic developments, interest rate
trends and other factors it deems relevant. In evaluating an issuer's
creditworthiness, the Investment Manager relies principally on its own analysis.
A security's credit rating is simply one factor that may be considered by the
Investment Manager in this regard.

Fixed-income securities are debt securities such as bonds, notes or commercial
paper. The issuer of the debt security borrows money from the investor who buys
the security. Most debt securities pay either fixed or adjustable rates of
interest at regular intervals until they mature, at which point investors get
their principal back. The Fund's fixed-income investments may include zero
coupon securities and payment-in-kind bonds. Zero coupon securities are
purchased at a discount and either (i) pay no interest, or (ii) accrue interest,
but make no payments until maturity; payment-in-kind bonds are purchased at the
face amount of the bond and accrue additional principal but make no payments
until maturity.

The remaining 20% of the Fund's assets may be invested in securities rated Baa
or BBB or higher (or, if not rated, determined to be of comparable quality when
the Investment Manager believes that such securities may produce attractive
yields.) The Fund may also invest in common stocks, asset-backed securities,
convertible securities, warrants and foreign securities.

In pursuing the Fund's investment objectives, the Investment Manager has
considerable leeway in deciding which investments it buys, holds or sells on a
day-to-day basis -- and which trading strategies it uses. For example, the
Investment Manager in its discretion may determine to use some permitted trading
strategies while not using others.

                                                                               1


[ICON]  PRINCIPAL RISKS
- --------------------------------------------------------------------------------
There is no assurance that the Fund will achieve its investment objectives. The
Fund's share price and yield will fluctuate with changes in the market value of
the Fund's portfolio securities. When you sell Fund shares, they may be worth
less than what you paid for them and, accordingly, you can lose money investing
in this Fund.

Fixed-Income Securities. Principal risks of investing in the Fund are associated
with its junk bond investments. All fixed-income securities, such as junk bonds,
are subject to two types of risk: credit risk and interest rate risk.

Credit risk refers to the possibility that the issuer of a security will be
unable to make interest payments and/or repay the principal on its debt.

Interest rate risk refers to fluctuations in the value of a fixed-income
security resulting from changes in the general level of interest rates. When the
general level of interest rates goes up, the prices of most fixed-income
securities go down. When the general level of interest rates goes down, the
prices of most fixed-income securities go up. (Zero coupon securities are
typically subject to greater price fluctuations than comparable securities that
pay interest.) As merely illustrative of the relationship between fixed-income
securities and interest rates, the following table shows how interest rates
affect bond prices.

Yields on Treasury securities are as of December 31, 2001. The table is not
representative of price changes for junk bonds. In addition, the table is an
illustration and does not represent expected yields or share price changes of
any Morgan Stanley mutual fund.

Junk Bonds. Junk bonds are subject to greater risk of loss of income and
principal than higher rated securities. The prices of junk bonds are likely to
be more sensitive to adverse economic changes or individual corporate
developments than higher rated securities. During an economic downturn or
substantial period of rising interest rates, junk bond issuers and, in
particular, highly leveraged issuers may experience financial stress that would
adversely affect their ability to service their principal and interest payment
obligations, to meet their projected business goals or to obtain additional
financing. In the event of a default, the Fund may incur additional expenses to
seek recovery. The secondary market for junk bonds 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 Rule 144A securities could have
the effect of increasing the level of Fund illiquidity to the extent the Fund
may be unable to find qualified institutional buyers interested in purchasing
the securities. The illiquidity of the market may also adversely affect the
ability of the Fund's Directors to arrive at a fair value for certain junk bonds
at certain times and could make it difficult for the Fund to sell certain
securities. In addition, periods of economic uncertainty and change probably
would result in an increased volatility of market prices of high yield
securities and a corresponding volatility in the Fund's net asset value. In
addition to junk bonds, the Fund may also invest in certain investment grade
fixed-income securities. Some of these securities have speculative
characteristics.

The performance of the Fund also will depend on whether or not the Investment
Manager is successful in applying the Fund's investment strategies. The Fund is
subject to other risks from its permissible investments including the risks
associated with its investments in common stocks, asset-backed securities,
warrants and foreign securities. For more information about these risks, see the
"Additional Risk Information" section.

Shares of the Fund are not bank deposits and are not guaranteed or insured by
the FDIC or any other government agency.

[ICON]  PAST PERFORMANCE
- --------------------------------------------------------------------------------

The bar chart and table below provide some indication of the risks of investing
in the Fund. The Fund's past performance (before and after taxes) does not
indicate how the Fund will perform in the future.

[Sidebar]
ANNUAL TOTAL RETURNS
This chart shows how the performance of the Fund's Class D shares has varied
from year to year over the past 10 calendar years.
[End Sidebar]


ANNUAL TOTAL RETURNS -- Calendar Years

1992 24.22%
'93  31.59%
'94  -7.15%
'95  17.13%
'96  13.27%
'97  12.90%
'98  -2.63%
'99  2.77%
2000 -30.61%
'01  -26.91%

The bar chart reflects the performance of Class D shares; the performance of the
other Classes will differ because the Classes have different ongoing fees. The
performance information in the bar chart does not reflect the deduction of sales
charges; if these amounts were reflected, returns would be less than shown.
Year-to-date total return as of June 30, 2002 was -5.14%.

During the periods shown in the bar chart, the highest return for a calendar
quarter was 17.06% (quarter ended March 31, 1992) and the lowest return for a
calendar quarter was -19.49% (quarter ended December 31, 2000).

(1)  Prior to July 28, 1997 the Fund offered only one class of shares. Because
     the distribution arrangement for Class A most closely resembled 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 5.50%
     sales charge in effect prior to July 28, 1997. In addition, Class A shares
     are now subject to an ongoing 12b-1 fee which is reflected in the restated
     performance for that class.
(2)  Classes B and C commenced operations on July 28, 1997.
(3)  Because all shares of the Fund held prior to July 28, 1997 were designated
     Class D shares, the Fund's historical performance has been restated to
     reflect the absence of any sales charge.
(4)  These returns do not reflect any tax consequences from a sale of your
     shares at the end of each period, but they do reflect any applicable sales
     charges on such a sale.
(5)  The Lehman Brothers U.S. Corporate High Yield Index tracks the performance
     of all below investment-grade securities which have at least $100 million
     in outstanding issuance, a maturity greater than one year, and are issued
     in fixed-rate U.S. dollar denominations. The Index does not include any
     expenses, fees or charges. The Index is unmanaged and should not be
     considered an investment.

The above table shows after tax returns for the Fund's Class A and Class D
Shares. The after tax returns for the Fund's other Classes will vary from the
Class A and Class D shares' returns. After tax returns are calculated using the
historical highest individual federal marginal income tax rates during the
period shown and do not reflect the impact of state and local taxes. Actual
after tax returns depend on an investor's tax situation and may differ from
those shown, and after tax returns are not relevant to investors who hold their
Fund shares through tax-deferred arrangements, such as 401(k) plans or
individual retirement accounts. After tax returns may be higher than before tax
returns due to an assumed benefit from capital losses that would have been
realized had Fund shares been sold at the end of the relevant periods.

[ICON]  FEES AND EXPENSES
- --------------------------------------------------------------------------------

The table below briefly describes the fees and expenses that you may pay if you
buy and hold shares of the Fund. The Fund offers four Classes of shares:
Classes A, B, C and D. Each Class has a different combination of fees, expenses
and other features, which should be considered in selecting a Class of shares.
The Fund does not charge account or exchange fees. See the "Share Class
Arrangements" section for further fee and expense information.

(1)  Reduced for purchases of $25,000 and over.
(2)  Investments that are not subject to any sales charge at the time of
     purchase are subject to a contingent deferred sales charge ("CDSC") of
     1.00% that will be imposed if you sell your shares within one year after
     purchase, except for certain specific circumstances.
(3)  The CDSC is scaled down to 1.00% during the sixth year, reaching zero
     thereafter. See "Share Class Arrangements" for a complete discussion of the
     CDSC.
(4)  Only applicable if you sell your shares within one year after purchase.

Example
This example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

The example assumes that you invest $10,000 in the Fund, your investment has a
5% return each year, and the Fund's operating expenses remain the same. Although
your actual costs may be higher or lower, the tables below show your costs at
the end of each period based on these assumptions depending upon whether or not
you sell your shares at the end of each period.



                        If You SOLD Your Shares:              If You HELD Your Shares:

While Class B and Class C shares do not have any front-end sales charges, their
higher ongoing annual expenses (due to higher 12b-1 fees) mean that over time
you could end up paying more for these shares than if you were to pay front-end
sales charges for Class A shares.

[ICON]  ADDITIONAL INVESTMENT STRATEGY INFORMATION
- --------------------------------------------------------------------------------
This section provides additional information relating to the Fund's principal
investment strategies.

Common Stocks. The Fund may invest up to 20% of its assets in common stocks.

Asset-Backed Securities. Asset-backed securities represent an interest in a pool
of assets such as automobile loans and credit card receivables or home equity
loans that have been securitized in pass through structures similar to
mortgage-backed securities. These types of pass through securities provide for
monthly payments that are a "pass through" of the monthly interest and principal
payments made by the individual borrowers on the pooled receivables.

Foreign Securities. The Fund may invest up to 20% of its assets in fixed-income
securities issued by foreign governments and other foreign issuers (including
American depositary receipts or other similar securities convertible into
securities of foreign issuers) but not more than 10% of its total assets in
these securities may be denominated in foreign currencies.

Warrants. The Fund may acquire warrants which may or may not be attached to
common stock. Warrants are options to purchase equity securities at a specific
price for a specific period of time.

Unit Offerings/Convertible Securities. The Fund may purchase units which combine
debt securities with equity securities and/or warrants. The Fund may invest in
convertible securities which are securities that generally pay interest and may
be converted into common stock.

Defensive Investing. The Fund may take temporary "defensive" positions in
attempting to respond to adverse market conditions. The Fund may invest any
amount of its assets in cash or money market instruments in a defensive posture
when the Investment Manager believes it is advisable to do so. Although taking a
defensive posture is designed to protect the Fund from an anticipated market
downturn, it could have the effect of reducing the benefit from any upswing in
the market. When the Fund takes a defensive position, it may not achieve its
investment objectives.

The percentage limitations relating to the composition of the Fund's portfolio
apply at the time the Fund acquires an investment. Subsequent percentage changes
that result from market fluctuations will not require the Fund to sell any
portfolio security. However, the Fund may be required to sell its illiquid
securities holdings, if any, in response to fluctuations in the value of such
holdings. The Fund may change its principal investment strategies without
shareholder approval; however, you would be notified of any changes.

[ICON]  ADDITIONAL RISK INFORMATION
- --------------------------------------------------------------------------------
This section provides additional information relating to the principal risks of
investing in the Fund.

Common Stocks. In general, stock values fluctuate in response to activities
specific to the company as well as general market, economic and political
conditions. These prices can fluctuate widely.

Asset-Backed Securities. Asset-backed securities have risk characteristics
similar to mortgage-backed securities. Like mortgage-backed securities, they
generally decrease in value as a result of interest rate increases, but may
benefit less than other fixed-income securities from declining interest rates,
principally because of prepayments. Also, as in the case of mortgage-backed
securities, prepayments generally increase during a period of declining interest
rates although other factors, such as changes in credit card use and payment
patterns, may also influence prepayment rates. Asset-backed securities also
involve the risk that various federal and state consumer laws and other legal
and economic factors may result in the collateral backing the securities being
insufficient to support payment on the securities.

Foreign Securities. The Fund's investments in foreign securities involve risks
that are in addition to the risks associated with domestic securities. One
additional risk is currency risk. In particular, the price of securities could
be adversely affected by changes in the exchange rate between U.S. dollars and a
foreign market's local currency.

Foreign securities also have risks related to economic and political
developments abroad, including any effects of foreign social, economic or
political instability. Foreign companies, in general, are not subject to the
regulatory requirements of U.S. companies and, as such, there may be less
publicly available information about these companies. Moreover, foreign
accounting, auditing and financial reporting standards generally are different
from 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 the 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 U.S. counterparts. In
addition, differences in clearance and settlement procedures in foreign markets
may occasion delays in settlements of the Fund's trades effected in those
markets.

Depositary receipts involve substantially identical risks to those associated
with direct investment in foreign securities. In addition, the underlying
issuers of certain depositary receipts, particularly unsponsored or unregistered

MORGAN STANLEY INVESTMENT ADVISORS INC.
The Investment Manager is widely recognized as a leader in the mutual fund
industry and together with Morgan Stanley Services Company Inc., its
wholly-owned subsidiary, had approximately $125 billion in assets under
management as of August 31, 2002.
[End Sidebar]


The Fund has retained the Investment Manager -- Morgan Stanley Investment
Advisors Inc. -- to provide administrative services, manage its business affairs
and invest its assets, including the placing of orders for the purchase and sale
of portfolio securities. The Investment Manager is a wholly-owned subsidiary of
Morgan Stanley, a preeminent global financial services firm that maintains
leading market positions in each of its three primary businesses: securities,
asset management and credit services. Its address is 1221 Avenue of the
Americas, New York, NY 10020.

The Fund's portfolio is managed by the Taxable Fixed-Income team. Current
members of the team include Stephen F. Esser, a Managing Director of the
Investment Manager, Gordon W. Loery, an Executive Director of the Investment
Manager, and Deanna L. Loughnane, an Executive Director of the Investment
Manager.

The Fund pays the Investment Manager a monthly management fee as full
compensation for the services and facilities furnished to the Fund, and for Fund
expenses assumed by the Investment Manager. The fee is based on the Fund's
average daily net assets. For the fiscal year ended August 31, 2002 the Fund
accrued total compensation to the Investment Manager amounting to 0.48% of the
Fund's average daily net assets.

Shareholder Information

[ICON]  PRICING FUND SHARES
- --------------------------------------------------------------------------------

The price of Fund shares (excluding sales charges), called "net asset value," is
based on the value of the Fund's portfolio securities. While the assets of each
Class are invested in a single portfolio of securities, the net asset value of
each Class will differ because the Classes have different ongoing distribution
fees.

The net asset value per share of the Fund is determined once daily at 4:00 p.m.
Eastern 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). Shares will not be priced on days that the New York Stock Exchange is
closed.

The value of the Fund's portfolio securities is based on the securities' market
price when available. When a market price is not readily available, including
circumstances under which the Investment Manager determines that a security's
market price is not accurate, a portfolio security is valued at its fair value,
as determined under procedures established by the Fund's Board of Directors. In
these cases, the Fund's net asset value will reflect certain portfolio
securities' fair value rather than their market price. With respect to
securities that are primarily listed on foreign exchanges, the value of the
Fund's portfolio securities may change on days when you will not be able to
purchase or sell your shares.

An exception to the Fund's general policy of using market prices concerns its
short-term debt portfolio securities. Debt securities with remaining maturities
of sixty days or less at the time of purchase are valued at amortized cost.
However, if the cost does not reflect the securities' market value, these
securities will be valued at their fair value.

authorized financial representative. Your Financial Advisor will assist you,
step-by-step, with the procedures to invest in the Fund. You may also purchase

Because every investor has different immediate financial needs and long-term
investment goals, the Fund offers investors four Classes of shares: Classes A,
B, C and D. Class D shares are only offered to a limited group of investors.
Each Class of shares offers a distinct structure of sales charges, distribution
and service fees, and other features that are designed to address a variety of
needs. Your Financial Advisor or other authorized financial representative can
help you decide which Class may be most appropriate for you. When purchasing
Fund shares, you must specify which Class of shares you wish to purchase.


                                                                               9




When you buy Fund shares, the shares are purchased at the next share price
calculated (less any applicable front-end sales charge for Class A shares) after
we receive your purchase order. Your payment is due on the third business day
after you place your purchase order. We reserve the right to reject any order
for the purchase of Fund shares.

[ICON]  HOW TO EXCHANGE SHARES
- --------------------------------------------------------------------------------

Permissible Fund Exchanges. You may exchange shares of any Class of the Fund for
the same Class of any other continuously offered Multi-Class Fund, or for shares
of a No-Load Fund, a Money Market Fund, North American Government Income Trust
or Limited Duration U.S. Treasury Trust, without the imposition of an exchange
fee. In addition, Class A shares of the Fund may be exchanged for shares of an
FSC Fund (funds subject to a front-end sales charge). See the inside back cover
of this PROSPECTUS for each Morgan Stanley Fund's designation as a Multi-Class
Fund, No-Load Fund, Money Market Fund or an FSC Fund. If a Morgan Stanley Fund
is not listed, consult the inside back cover of that fund's prospectus for its
designation.

Exchanges may be made after shares of the fund acquired by purchase have been
held for thirty days. There is no waiting period for exchanges of shares
acquired by exchange or dividend reinvestment. The current prospectus for each
fund describes its investment objective(s), policies and investment minimums,
and should be read before investment. Since exchanges are available only into
continuously offered Morgan Stanley Funds, exchanges are not available into any
new Morgan Stanley Fund during its initial offering period, or when shares of a
particular Morgan Stanley Fund are not being offered for purchase.

Exchange Procedures. You can process an exchange by contacting your Morgan
Stanley Financial Advisor or other authorized financial representative.
Otherwise, you must forward an exchange privilege authorization form to the
Fund's transfer agent -- Morgan Stanley Trust -- and then write the transfer
agent or call (800) 869-NEWS to place an exchange order. You can obtain an
exchange privilege authorization form by contacting your Financial Advisor or
other authorized financial representative or by calling (800) 869-NEWS. If you
hold share certificates, no exchanges may be processed until we have received
all applicable share certificates.

An exchange to any Morgan Stanley Fund (except a Money Market Fund) is made on
the basis of the next calculated net asset values of the funds involved after
the exchange instructions are accepted. When exchanging into a Money Market
Fund, the Fund's shares are sold at their next calculated net asset value and
the Money Market Fund's shares are purchased at their net asset value on the
following business day.

The Fund may terminate or revise the exchange privilege upon required notice.
The check writing privilege is not available for Money Market Fund shares you
acquire in an exchange.

Telephone Exchanges. For your protection when calling Morgan Stanley Trust, we
will employ reasonable procedures to confirm that exchange instructions
communicated over the telephone are genuine. These procedures may include
requiring various forms of personal identification such as name, mailing
address, social security or other tax identification number. Telephone
instructions also may be recorded.

Telephone instructions will be accepted if received by the Fund's transfer agent
between 9:00 a.m. and 4:00 p.m. Eastern time on any day the New York Stock
Exchange is open for business. During periods of drastic economic or market
changes, it is possible that the telephone exchange procedures may be difficult
to implement, although this has not been the case with the Fund in the past.

Margin Accounts. If you have pledged your Fund shares in a margin account,
contact your Morgan Stanley Financial Advisor or other authorized financial
representative regarding restrictions on the exchange of such shares.

                                                                              11


Tax Considerations of Exchanges. If you exchange shares of the Fund for shares
of another Morgan Stanley Fund there are important tax considerations. For tax
purposes, the exchange out of the Fund is considered a sale of Fund shares --
and the exchange into the other fund is considered a purchase. As a result, you
may realize a capital gain or loss.

You should review the "Tax Consequences" section and consult your own tax
professional about the tax consequences of an exchange.

Limitations on Exchanges. Certain patterns of past exchanges and/or purchase or
sale transactions involving the Fund or other Morgan Stanley Funds may result in
the Fund limiting or prohibiting, at its discretion, additional purchases and/or
exchanges. Determinations in this regard may be made based on the frequency or
dollar amount of the previous exchanges or purchase or sale transactions. You
will be notified in advance of limitations on your exchange privileges.

CDSC Calculations on Exchanges. See the "Share Class Arrangements" section of
this PROSPECTUS for a further discussion of how applicable contingent deferred
sales charges (CDSCs) are calculated for shares of one Morgan Stanley Fund that
are exchanged for shares of another.

For further information regarding exchange privileges, you should contact your
Morgan Stanley Financial Advisor or call (800) 869-NEWS.

- --------------------------------------------------------------------------------
 SYSTEMATIC         If your investment in all of the Morgan Stanley Funds has a
 WITHDRAWAL PLAN    total market value of at least $10,000, you may elect to
 [ICON]             withdraw amounts of $25 or more, or in any whole percentage
                    of a fund's balance (provided the amount is at least $25),
                    on a monthly, quarterly, semi-annual or annual basis, from
                    any fund with a balance of at least $1,000. Each time you
                    add a fund to the plan, you must meet the plan requirements.
                    ------------------------------------------------------------
                    Amounts withdrawn are subject to any applicable CDSC. A CDSC
                    may be waived under certain circumstances. See the Class B
                    waiver categories listed in the "Share Class Arrangements"
                    section of this PROSPECTUS.
                    ------------------------------------------------------------
                    To sign up for the Systematic Withdrawal Plan, contact your
                    Morgan Stanley Financial Advisor or call (800) 869-NEWS. You
                    may terminate or suspend your plan at any time. Please
                    remember that withdrawals from the plan are sales of shares,
                    not Fund "distributions," and ultimately may exhaust your
                    account balance. The Fund may terminate or revise the plan
                    at any time.
- --------------------------------------------------------------------------------


Payment for Sold Shares. After we receive your complete instructions to sell as
described above, a check will be mailed to you within seven days, although we
will attempt to make payment within one business day. Payment may also be sent
to your brokerage account.

Payment may be postponed or the right to sell your shares suspended under
unusual circumstances. If you request to sell shares that were recently
purchased by check, your sale will not be effected until it has been verified
that the check has been honored.

Tax Considerations. Normally, your sale of Fund shares is subject to federal and
state income tax. You should review the "Tax Consequences" section of this
Prospectus and consult your own tax professional about the tax consequences of a
sale.

Reinstatement Privilege. If you sell Fund shares and have not previously
exercised the reinstatement privilege, you may, within 35 days after the date of
sale, invest any portion of the proceeds in the same Class of Fund shares at
their net asset value and receive a pro rata credit for any CDSC paid in
connection with the sale.

Involuntary Sales. The Fund reserves the right, on sixty days' notice, to sell
the shares of any shareholder (other than shares held in an IRA or 403(b)
Custodial Account) whose shares, due to sales by the shareholder, have a value
below $100, or in the case of an account opened through EasyInvest(SM), if after
12 months the shareholder has invested less than $1,000 in the account.

                                                                              13



However, before the Fund sells your shares in this manner, we will notify you
and allow you sixty days to make an additional investment in an amount that will
increase the value of your account to at least the required amount before the
sale is processed. No CDSC will be imposed on any involuntary sale.

Margin Accounts. If you have pledged your Fund shares in a margin account,
contact your Morgan Stanley Financial Advisor or other authorized financial
representative regarding restrictions on the sale of such shares.

[ICON]  DISTRIBUTIONS
- --------------------------------------------------------------------------------

[Sidebar]
TARGETED DIVIDENDS(SM)
You may select to have your Fund distributions automatically invested in other
Classes of Fund shares or Classes of another Morgan Stanley Fund that you own.
Contact your Morgan Stanley Financial Advisor for further information about this
service.
[End Sidebar]

The Fund passes substantially all of its earnings from income and capital gains
along to its investors as "distributions." The Fund earns income from stocks and
interest from fixed-income investments. These amounts are passed along to Fund
shareholders as "income dividend distributions." The Fund realizes capital gains
whenever it sells securities for a higher price than it paid for them. These
amounts may be passed along as "capital gain distributions."

The Fund declares income dividends separately for each Class. Distributions paid
on Class A and Class D shares usually will be higher than for Class B and Class
C because distribution fees that Class B and Class C pay are higher. Normally,
income dividends are distributed to shareholders monthly. Capital gains, if any,
are usually distributed in December. The Fund, however, may retain and reinvest
any long-term capital gains. The Fund may at times make payments from sources
other than income or capital gains that represent a return of a portion of your
investment.

Distributions are reinvested automatically in additional shares of the same
Class and automatically credited to your account, unless you request in writing
that all distributions be paid in cash. If you elect the cash option, the Fund
will mail a check to you no later than seven business days after the
distribution is declared. However, if you purchase Fund shares through a
Financial Advisor within three business days prior to the record date for the
distribution, the distribution will automatically be paid to you in cash, even
if you did not request to receive all distributions in cash. No interest will
accrue on uncashed checks. If you wish to change how your distributions are
paid, your request should be received by the Fund's transfer agent, Morgan
Stanley Trust, at least five business days prior to the record date of the
distributions.

[ICON]  TAX CONSEQUENCES
- --------------------------------------------------------------------------------

As with any investment, you should consider how your Fund investment will be
taxed. The tax information in this Prospectus is provided as general
information. You should consult your own tax professional about the tax
consequences of an investment in the Fund.

Unless your investment in the Fund is through a tax-deferred retirement account,
such as a 401(k) plan or IRA, you need to be aware of the possible tax
consequences when:

o    The Fund makes distributions; and

o    You sell Fund shares, including an exchange to another Morgan Stanley Fund.

 14


Taxes on Distributions. Your distributions are normally subject to federal and
state income tax when they are paid, whether you take them in cash or reinvest
them in Fund shares. A distribution also may be subject to local income tax. Any
income dividend distributions and any short-term capital gain distributions are
taxable to you as ordinary income. Any long-term capital gain distributions are
taxable as long-term capital gains, no matter how long you have owned shares in
the Fund.

Every January, you will be sent a statement (IRS Form 1099-DIV) showing the
taxable distributions paid to you in the previous year. The statement provides
information on your dividends and capital gains for tax purposes.

Taxes on Sales. Your sale of Fund shares normally is subject to federal and
state income tax and may result in a taxable gain or loss to you. A sale also
may be subject to local income tax. Your exchange of Fund shares for shares of
another Morgan Stanley Fund is treated for tax purposes like a sale of your
original shares and a purchase of your new shares. Thus, the exchange may, like
a sale, result in a taxable gain or loss to you and will give you a new tax
basis for your new shares.

When you open your Fund account, you should provide your social security or tax
identification number on your investment application. By providing this
information, you will avoid being subject to a federal backup withholding tax
(approximately 30% currently) on taxable distributions and redemption proceeds.
Any withheld amount would be sent to the IRS as an advance tax payment.


[ICON]  SHARE CLASS ARRANGEMENTS
- --------------------------------------------------------------------------------

The Fund offers several Classes of shares having different distribution
arrangements designed to provide you with different purchase options according
to your investment needs. Your Morgan Stanley Financial Advisor or other
authorized financial representative can help you decide which Class may be
appropriate for you.

The general public is offered three Classes: Class A shares, Class B shares and
Class C shares, which differ principally in terms of sales charges and ongoing
expenses. A fourth Class, Class D shares, is offered only to a limited category
of investors. Shares that you acquire through reinvested distributions will not
be subject to any front-end sales charge or CDSC -- contingent deferred sales
charge.

Sales personnel may receive different compensation for selling each Class of
shares. The sales charges applicable to each Class provide for the distribution
financing of shares of that Class.

The chart below compares the sales charge and annual 12b-1 fee applicable to
each Class:



                                                                              MAXIMUM
CLASS    SALES CHARGE                                                     ANNUAL 12B-1 FEE

 A       Maximum 4.25% initial sales charge reduced for purchase of
         $25,000 or more; shares sold without an initial sales charge
         are generally subject to a 1.0% CDSC during the first year            0.25%
- ---------------------------------------------------------------------------------------------
 B       Maximum 5.0% CDSC during the first year decreasing to 0%
         after six years                                                       0.75%
- ---------------------------------------------------------------------------------------------
 C       1.0% CDSC during the first year                                       0.85%
- ---------------------------------------------------------------------------------------------
 D       None                                                                   None
- ---------------------------------------------------------------------------------------------


                                                                              15




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 purchases of
$25,000 or more according to the schedule below. Investments of $1 million or
more are not subject to an initial sales charge, but are generally subject to a
contingent deferred sales charge, or CDSC, of 1.0% on sales made within one year
after the last day of the month of purchase. The CDSC will be assessed in the
same manner and with the same CDSC waivers as with Class B shares. Class A
shares are also subject to a distribution (12b-1) fee of up to 0.25% of the
average daily net assets of the Class. This fee is lower than the distribution
fee paid by Class B or Class C shares.

The Fund will not accept a purchase order for Class A shares that qualifies for
investment in Class D shares.

The offering price of Class A shares includes a sales charge (expressed as a
percentage of the offering price) on a single transaction as shown in the
following table:

[Sidebar]
FRONT-END SALES CHARGE OR FSC
An initial sales charge you pay when purchasing Class A shares that is based on
a percentage of the offering price. The percentage declines based upon the
dollar value of Class A shares you purchase. We offer three ways to reduce your
Class A sales charges -- the Combined Purchase Privilege, Right of Accumulation
and Letter of Intent.

The reduced sales charge schedule is applicable to purchases of Class A shares
in a single transaction by:

o    A single account (including an individual, trust or fiduciary account).

o    Family member accounts (limited to husband, wife and children under the age
     of 21).

o    Pension, profit sharing or other employee benefit plans of companies and
     their affiliates.

o    Tax-exempt organizations.

o    Groups organized for a purpose other than to buy mutual fund shares.

Combined Purchase Privilege. You also will have the benefit of reduced sales
charges by combining purchases of Class A shares of the Fund in a single
transaction with purchases of Class A shares of other Multi-Class Funds and
shares of FSC Funds.

Right of Accumulation. You also may benefit from a reduction of sales charges if
the cumulative net asset value of Class A shares of the Fund purchased in a
single transaction, together with shares of other funds you currently own which
were previously purchased at a price including a front-end sales charge (or
Class A shares purchased at

16


$1 million or more), and shares acquired through reinvestment of distributions,
amounts to $25,000 or more. Also, if you have a cumulative net asset value of
all your Class A and Class D shares equal to at least $5 million (or
$25 million for certain employee benefit plans), you are eligible to purchase
Class D shares of any fund subject to the fund's minimum initial investment
requirement.

You must notify your Morgan Stanley Financial Advisor or other authorized
financial representative (or Morgan Stanley Trust if you purchase directly
through the Fund), at the time a purchase order is placed, that the purchase
qualifies for the reduced sales charge under the Right of Accumulation. Similar
notification must be made in writing when an order is placed by mail. The
reduced sales charge will not be granted if: (i) notification is not furnished
at the time of the order; or (ii) a review of the records of Morgan Stanley DW
Inc. ("Morgan Stanley DW") or other authorized dealer of Fund shares or the
Fund's transfer agent does not confirm your represented holdings.

Letter of Intent. The schedule of reduced sales charges for larger purchases
also will be available to you if you enter into a written "Letter of Intent." A
Letter of Intent provides for the purchase of Class A shares of the Fund or
other Multi-Class Funds or shares of FSC Funds within a thirteen-month period.
The initial purchase under a Letter of Intent must be at least 5% of the stated
investment goal. To determine the applicable sales charge reduction, you may
also include: (1) the cost of shares of other Morgan Stanley Funds which were
previously purchased at a price including a front-end sales charge during the
90-day period prior to the distributor receiving the Letter of Intent, and
(2) the cost of shares of other funds you currently own acquired in exchange for
shares of funds purchased during that period at a price including a front-end
sales charge. You can obtain a Letter of Intent by contacting your Morgan
Stanley Financial Advisor or other authorized financial representative, or by
calling (800) 869-NEWS. If you do not achieve the stated investment goal within
the thirteen-month period, you are required to pay the difference between the
sales charges otherwise applicable and sales charges actually paid, which may be
deducted from your investment.

Other Sales Charge Waivers. In addition to investments of $1 million or more,
your purchase of Class A shares is not subject to a front-end sales charge (or a
CDSC upon sale) if your account qualifies under one of the following categories:

o    A trust for which Morgan Stanley Trust provides discretionary trustee
     services.

o    Persons participating in a fee-based investment program (subject to all of
     its terms and conditions, including termination fees, and mandatory sale or
     transfer restrictions on termination) approved by the Fund's distributor
     pursuant to which they pay an asset-based fee for investment advisory,
     administrative and/or brokerage services.

o    Qualified state tuition plans described in Section 529 of the Internal
     Revenue Code and donor-advised charitable gift funds (subject to all
     applicable terms and conditions) and certain other investment programs that
     do not charge an asset-based fee and have been approved by the Fund's
     distributor.

o    Employer-sponsored employee benefit plans, whether or not qualified under
     the Internal Revenue Code, for which (i) Morgan Stanley Trust serves as
     trustee. (ii) Morgan Stanley's Retirement Plan Services serves as
     recordkeeper under a written Recordkeeping Services Agreement or (iii) an
     entity independent from Morgan Stanley serves as recordkeeper under an
     alliance or similar agreement with Morgan Stanley's Retirement Plan
     Services (together, "Morgan Stanley Eligible Plans"), provided that, in the
     case of (i) and (ii) above, any such plan has at least 200 eligible
     employees.


                                                                              17



o    A Morgan Stanley Eligible Plan whose Class B shares have converted to Class
     A shares, regardless of the plan's asset size or number of eligible
     employees.

o    Insurance company separate accounts that have been approved by the Fund's
     distributor.

o    A client of a Morgan Stanley Financial Advisor who joined us from another
     investment firm within six months prior to the date of purchase of Fund
     shares, and who used the proceeds from the sale of shares of a proprietary
     mutual fund of that Financial Advisor's previous firm that imposed either a
     front-end or deferred sales charge to purchase Class A shares, provided
     that: (1) the client sold the shares not more than 60 days prior to the
     purchase of Fund shares, and (2) the sale proceeds were maintained in the
     interim in cash or a Money Market Fund.

o    Current or retired Directors or Trustees of the Morgan Stanley Funds, such
     persons' spouses and children under the age of 21, and trust accounts for
     which any of such persons is a beneficiary.

o    Current or retired directors, officers and employees of Morgan Stanley and
     any of its subsidiaries, such persons' spouses and children under the age
     of 21, and trust accounts for which any such persons is a beneficiary.

CLASS B SHARES Class B shares are offered at net asset value with no initial
sales charge but are subject to a contingent deferred sales charge, or CDSC, as
set forth in the table below. For the purpose of calculating the CDSC, shares
are deemed to have been purchased on the last day of the month during which they
were purchased.

[Sidebar]
CONTINGENT DEFERRED SALES CHARGE OR CDSC
A fee you pay when you sell shares of certain Morgan Stanley Funds purchased
without an initial sales charge. This fee declines the longer you hold your

Each time you place an order to sell or exchange shares, shares with no CDSC
will be sold or exchanged first, then shares with the lowest CDSC will be sold
or exchanged next. For any shares subject to a CDSC, the CDSC will be assessed
on an amount equal to the lesser of the current market value or the cost of the
shares being sold.

The Fund will generally not accept a purchase order for Class B shares in the
amount of $100,000 or more.

CDSC Waivers. A CDSC, if otherwise applicable, will be waived in the case of:

o    Sales of shares held at the time you die or become disabled (within the
     definition in Section 72(m)(7) of the Internal Revenue Code which relates
     to the ability to engage in gainful employment), if the shares are: (i)
     registered either in your name (not a trust) or in the names of you and
     your spouse as joint tenants with

 18


     right of survivorship; or (ii) held in a qualified corporate or
     self-employed retirement plan, IRA or 403(b) Custodial Account, provided in
     either case that the sale is requested within one year of your death or
     initial determination of disability.

o    Sales in connection with the following retirement plan "distributions": (i)
     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); (ii)
     distributions from an IRA or 403(b) Custodial Account following attainment
     of age 59 1/2; or (iii) a tax-free return of an excess IRA contribution (a
     "distribution" does not include a direct transfer of IRA, 403(b) Custodial
     Account or retirement plan assets to a successor custodian or trustee).

o    Sales of shares held for you as a participant in a Morgan Stanley Eligible
     Plan.

o    Sales of shares in connection with the Systematic Withdrawal Plan of up to
     12% annually of the value of each fund from which plan sales are made. The
     percentage is determined on the date you establish the Systematic
     Withdrawal Plan and based on the next calculated share price. You may have
     this CDSC waiver applied in amounts up to 1% per month, 3% per quarter, 6%
     semi-annually or 12% annually. Shares with no CDSC will be sold first,
     followed by those with the lowest CDSC. As such, the waiver benefit will be
     reduced by the amount of your shares that are not subject to a CDSC. If you
     suspend your participation in the plan, you may later resume plan payments
     without requiring a new determination of the account value for the 12% CDSC
     waiver.

o    Sales of shares if you simultaneously invest the proceeds in the Investment
     Manager's mutual fund asset allocation program, pursuant to which investors
     pay an asset-based fee. Any shares you acquire in connection with the
     Investment Manager's mutual fund asset allocation program are subject to
     all of the terms and conditions of that program, including termination
     fees, and mandatory sale or transfer restrictions on termination.

All waivers will be granted only following the Fund's distributor receiving
confirmation of your entitlement. If you believe you are eligible for a CDSC
waiver, please contact your Financial Advisor or call (800) 869-NEWS.

Distribution Fee. Class B shares are subject to an annual distribution (12b-1)
fee of 0.75% of the average daily net assets of Class B. This fee is higher than
the annual distribution fee paid by Class A.

Conversion Feature. After ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund with no initial sales charge. The
ten year period runs 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, from
the last day of the month in which the original Class B shares were purchased;
the shares will convert to Class A shares based on their relative net asset
values in the month following the ten year period. At the same time, an equal
proportion of Class B shares acquired through automatically reinvested
distributions will convert to Class A shares on the same basis.

In the case of Class B shares held in a Morgan Stanley Eligible Plan, 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 Class B shares of a Morgan Stanley Fund
purchased by that plan.

Currently, the Class B share conversion is not a taxable event; the conversion
feature may be cancelled if it is deemed a taxable event in the future by the
Internal Revenue Service.

                                                                              19


If you exchange your Class B shares for shares of a Money Market Fund, a No-Load
Fund, North American Government Income Trust or Limited Duration U.S. Treasury
Trust, the holding period for conversion is frozen as of the last day of the
month of the exchange and resumes on the last day of the month you exchange back
into Class B shares.

Exchanging Shares Subject to a CDSC. There are special considerations when you
exchange Fund shares that are subject to a CDSC. When determining the length of
time you held the shares and the corresponding CDSC rate, any period (starting
at the end of the month) during which you held shares of a fund that does not
charge a CDSC will not be counted. Thus, in effect the "holding period" for
purposes of calculating the CDSC is frozen upon exchanging into a fund that does
not charge a CDSC.

For example, if you held Class B shares of the Fund for one year, exchanged to
Class B of another Morgan Stanley Multi-Class Fund for another year, then sold
your shares, a CDSC rate of 4% would be imposed on the shares based on a two
year holding period -- one year for each fund. However, if you had exchanged the
shares of the Fund for a Money Market Fund (which does not charge a CDSC)
instead of the Multi-Class Fund, then sold your shares, a CDSC rate of 5% would
be imposed on the shares based on a one year holding period. The one year in the
Money Market Fund would not be counted. Nevertheless, if shares subject to a
CDSC are exchanged for a fund that does not charge a CDSC, you will receive a
credit when you sell the shares equal to the distribution (12b-1) fees, if any,
you paid on those shares while in that fund up to the amount of any applicable
CDSC.

In addition, shares that are exchanged into or from a Morgan Stanley Fund
subject to a higher CDSC rate will be subject to the higher rate, even if the
shares are re-exchanged into a fund with a lower CDSC rate.

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 sales made within one year after the
last day of the month of purchase. The CDSC will be assessed in the same manner
and with the same CDSC waivers as with Class B shares. The Fund will not accept
a purchase order for Class C shares in the amount of $1 million or more.

Distribution Fee. Class C shares are subject to an annual distribution (12b-1)
fee of up to 0.85% of the average daily net assets of that Class. This fee is
higher than the annual distribution fee paid by Class A. Unlike Class B shares,
Class C shares have no conversion feature and, accordingly, an investor that
purchases Class C shares may be subject to distribution (12b-1) fees applicable
to Class C shares for an indefinite period.

CLASS D SHARES Class D shares are offered without any sales charge on purchases
or sales and without any distribution (12b-1) fee. Class D shares are offered
only to investors meeting an initial investment minimum of $5 million ($25
million for Morgan Stanley Eligible Plans) and the following investor
categories:

o    Investors participating in the Investment Manager's mutual fund asset
     allocation program (subject to all of its terms and conditions, including
     termination fees, and mandatory sale or transfer restrictions on
     termination) pursuant to which they pay an asset-based fee.

o    Persons participating in a fee-based investment program (subject to all of
     its terms and conditions, including termination fees, and mandatory sale or
     transfer restrictions on termination) approved by the Fund's distributor

 20


     pursuant to which they pay an asset-based fee for investment advisory,
     administrative and/or brokerage services. With respect to Class D shares
     held through the Morgan Stanley Choice Program, at such time as those Fund
     shares are no longer held through the program, the shares will be
     automatically converted into Class A shares (which are subject to higher
     expenses than Class D shares) based on the then current relative net asset
     values of the two Classes.

o    Certain investment programs that do not charge an asset-based fee and have
     been approved by the Fund's distributor.

o    Employee benefit plans maintained by Morgan Stanley or any of its
     subsidiaries for the benefit of certain employees of Morgan Stanley and its
     subsidiaries.

o    Certain unit investment trusts sponsored by Morgan Stanley DW.

o    Certain other open-end investment companies whose shares are distributed by
     the Fund's distributor.

o    Investors who were shareholders of the Dean Witter Retirement Series on
     September 11, 1998 for additional purchases for their former Dean Witter
     Retirement Series accounts.

A purchase order meeting the requirements for investment in Class D will only be
accepted for Class D shares.

Class D shares are not offered for investments made through Section 529 plans,
donor-advised charitable gift funds and insurance company separate accounts that
have been approved by the Fund's distributor (regardless of the size of the
investment).

Meeting Class D Eligibility Minimums. To meet the $5 million ($25 million for
Morgan Stanley Eligible Plans) initial investment to qualify to purchase
Class D shares you may combine: (1) purchases in a single transaction of
Class D shares of the Fund and other Morgan Stanley Multi-Class Funds; and/or
(2) previous purchases of Class A and Class D shares of Multi-Class Funds and
shares of FSC Funds you currently own, along with shares of Morgan Stanley Funds
you currently own that you acquired in exchange for those shares.

NO SALES CHARGES FOR REINVESTED CASH DISTRIBUTIONS If you receive a cash payment
representing an income dividend or capital gain and you reinvest that amount in
the applicable Class of shares by returning the check within 30 days of the
payment date, the purchased shares would not be subject to an initial sales
charge or CDSC.

PLAN OF DISTRIBUTION (RULE 12b-1 FEES) The Fund has adopted a Plan of
Distribution in accordance with Rule 12b-1 under the Investment Company Act of
1940 with respect to the distribution of Class A, Class B and Class C shares.
(Class D shares are offered without any distribution fee.) The Plan allows the
Fund to pay distribution fees for the sale and distribution of these shares. It
also allows the Fund to pay for services to shareholders of Class A, Class B and
Class C shares. Because these fees are paid out of the Fund's assets on an
ongoing basis, over time these fees will increase the cost of your investment in
these Classes and may cost you more than paying other types of sales charges.


                                                                              21


Financial Highlights

The financial highlights table is intended to help you understand the Fund's
financial performance for the periods indicated. Certain information reflects
financial results for a single Fund share throughout each period. The total
returns in the table represent the rate an investor would have earned or lost on
an investment in the Fund (assuming reinvestment of all dividends and
distributions).

This information has been audited by Deloitte & Touche LLP, independent
auditors, whose report, along with the Fund's financial statements, is included
in the annual report, which is available upon request.

(THE FUND'S INVESTMENT COMPANY ACT FILE NO. IS 811-2932)


Morgan Stanley High Yield Securities Inc.
LETTER TO THE SHAREHOLDERS o AUGUST 31, 2002

DEAR SHAREHOLDER:

The 12 months ended August 31, 2002 were extremely volatile for the high-yield
market. The tragic events of September 11th had a profound effect on the economy
as well as the high-yield and equity markets. A flight-to-quality mentality
emerged, pushing equities and high-yield security prices sharply lower. After
the September decline, the high-yield market bounced back over the next seven
months. The economic recovery early in 2002 contributed to the improved tone of
the market. Strong flows of about $9 billion into the high-yield asset class in
January through May pushed prices higher.

However, the high-yield market weakened again during the balance of the review
period as the economy slowed and accounting scandals at WorldCom and other
companies shocked market participants. As you may be aware, WorldCom reported
that it had misclassified nearly $3.9 billion in costs (and later announced
additional improprieties). This announcement caused the market to fall
significantly in late June as investor confidence eroded. Strong inflows into
the high-yield asset class stopped as investors withdrew approximately $2
billion in June and July. The size of net redemptions led to sales of portfolio
holdings by mutual funds and dealers, further lowering prices. There was a
modest improvement in the second half of August, but it is too early to know if
the improvement will be sustained.

On balance, credit spreads in the high-yield market relative to U.S. Treasury
securities widened to historically wide levels. Spreads especially widened
within the lower-rated portion of the high-yield market as investors continued
to prefer investments in the relatively higher-quality end of the marketplace.
In addition, bonds in sectors related to telecommunications, cable and utilities
performed poorly as investors continued to be concerned about accounting
scandals and slower economic growth going forward.

PERFORMANCE AND PORTFOLIO STRATEGY

During the 12-month period ended August 31, 2002, Morgan Stanley High Yield
Securities' Class A and D shares produced returns of -21.70 percent and -21.45
percent, respectively. The Fund underperformed the Lehman Brothers U.S.
Corporate High Yield Index, which returned -7.65 percent. For the same period,
the Fund's Class B and C shares had total returns of -22.00 percent and -22.11
percent, respectively. The performance of the Fund's four share classes varies
because of differing expenses. Total return figures shown assume the
reinvestment of all distributions but do not reflect the deduction of any
applicable sales charges. If sales charges were included, performance would be
lower. The accompanying chart compares the Fund's performance to that of the
Lehman Index.

The past three years have been one of the most difficult periods for the
high-yield market. As a result of the substantial weakness in the market,
high-yield bond prices have declined sharply and yields have risen over much of
this period. The Fund's positions in the lower-rated portion of the market and
in

LETTER TO THE SHAREHOLDERS o AUGUST 31, 2002 CONTINUED

communications-related industries have been adversely affected. The last four
months represented an extension of these difficulties.

The Fund's allocations in the fixed-line communications, wireless communications
and cable industries contributed to its disappointing performance during the
review period. Fixed-line communications and cable were down by more than 30
percent and wireless was down 25 percent over the past 12 months,
underperforming the rest of the high-yield market. These industries experienced
slower revenue growth, higher default rates and many rating downgrades, factors
which led to lower prices for most bonds in these industries. Despite the Fund's
investments in these industries having been reduced over the past year,
allocations remained above market weights, thus adversely affecting performance.

Performance was helped by the higher-quality bonds added to the portfolio over
the past year, particularly those in the housing and health-care sectors. These
sectors performed better than most others in the high-yield market. Finally, an
underweighting of the utilities sector helped mitigate losses when this sector
came under pressure as a result of accounting concerns.

Over the course of the fiscal year, the Fund's portfolio management team
continued to reposition the portfolio for the current market environment. New
positions were initiated in many companies, including Starwood Hotels, Collins
and Aikman, Venetian Casino, Intermet, Metaldyne and Foamex. The team increased
the Fund's overall credit quality by buying BB-rated and BBB-rated securities
and decreasing exposure to telecommunications-related industries.

At fiscal year-end the Fund was overweighted toward wireline communications,
cable, wireless communications and media, as well as manufacturing and housing.
Underweighted positions included consumer products and retail. The Fund's
portfolio management team believes that consumer spending is likely to lag the
growth of the overall economy. The Fund also is underweighted toward aerospace,
as a result of slow demand in travel.

LOOKING AHEAD

June and July were two of the worst back-to-back months in the history of the
high-yield market. The market recovered modestly during the second half of
August. Although the spread widening that has occurred over the last few months
makes the market look attractive, it is uncertain how long it will take to
restore investor confidence. To some extent the market's returns will depend on
whether the economy continues its recovery without an intervening contraction.

Morgan Stanley High Yield Securities Inc.
LETTER TO THE SHAREHOLDERS o AUGUST 31, 2002 CONTINUED

We believe that the economy will continue on the path of recovery and that
investor confidence will recover with it over the coming months. Although timing
the high-yield market's turnaround is hard to predict, our long-term outlook for
the asset class remains positive.

We appreciate your ongoing support of Morgan Stanley High Yield Securities and
look forward to continuing to serve your investment needs.

Very truly yours,

NOTES TO FINANCIAL STATEMENTS o AUGUST 31, 2002

1. Organization and Accounting Policies

Morgan Stanley High Yield Securities Inc. (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 was
incorporated in Maryland on June 14, 1979 and commenced operations on
September 26, 1979. On July 28, 1997, the Fund converted to a multiple class
share structure.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year, six
years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) an equity portfolio security listed or traded
on the New York or American Stock Exchange, Nasdaq, or other exchange is valued
at its latest sale price, 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; (3) when market quotations are not readily available, including
circumstances under which it is determined by Morgan Stanley Investment Advisors
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

                                       20

NOTES TO FINANCIAL STATEMENTS o AUGUST 31, 2002 continued

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 and premiums are amortized over the respective life of
the securities. Interest income is accrued daily except where collection is not
expected.

C. Joint Repurchase Agreement Account -- Pursuant to an Exemptive Order issued
by the Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Manager, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, or U.S. Treasury or federal agency obligations.

D. Multiple Class Allocations -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.

E. 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 substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

F. Dividends and Distributions to Shareholders -- The Fund records dividends and
distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes

are reported as dividends in excess of net investment income or distributions in
excess of net realized capital gains. To the extent they exceed net investment
income and net realized capital gains for tax purposes, they are reported as
distributions of paid-in-capital.

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.

3. Plan of Distribution
Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The Plan
provides that the Fund pay the Distributor a fee which is accrued daily and paid
monthly at the following annual rates: (i) Class A -- up to 0.25% of the average
daily net assets of Class A; (ii) Class B -- 0.75% of the average daily net
assets of Class B; and (iii) Class C -- up to 0.85% of the average daily net
assets of Class C.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Directors will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that such excess amounts totaled
$60,068,745 at August 31, 2002.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 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 credit to Morgan Stanley Financial Advisors or other selected
broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the year ended August 31, 2002, the distribution fee was accrued for
Class A shares and Class C shares at the annual rate of 0.18% and 0.85%,
respectively.

The Distributor has informed the Fund that for the year ended August 31, 2002,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class A Shares, Class B shares and Class C shares of $26,842, $1,519,542
and $29,347, respectively and received $135,390 in front-end sales charges from
sales of the Fund's Class A shares. The respective shareholders pay such charges
which are not an expense of the Fund.

4. Security Transactions and Transactions with Affiliates

short-term investments, for the year ended August 31, 2002, aggregated

As of August 31, 2002, the Fund had temporary book/tax differences primarily
attributable to post-October losses, capital loss deferrals on wash sales, book
amortization of discounts on debt securities and interest and amortization of
discounts on bonds in default. The Fund had permanent book/tax differences
primarily attributable to an expired capital loss carryover and tax adjustments
on debt securities sold by the Fund. To reflect reclassifications arising from
the permanent differences, paid-in-capital was charged $172,175,337, dividends
in excess of net investment income was charged $948,800 and accumulated net
realized loss was credited $173,124,137.

7. Change in Accounting Policy
Effective September 1, 2001, the Fund has adopted the provisions of the AICPA
Audit and Accounting Guide for Investment Companies, as revised, related to
premiums and discounts on debt securities. The cumulative effect of this
accounting change had no impact on the net assets of the Fund, but resulted in a
$5,326,859 increase in the cost of securities and a corresponding increase in
undistributed net investment income based on securities held as of August 31,
2001.

The effect of this change for the year ended August 31, 2002 was to increase net
investment income by $4,981,336; increase unrealized depreciation by $3,780,819;
and increase net realized losses by $1,200,517. The statement of changes in net
assets and the financial highlights for prior periods have not been restated to
reflect this change.

8. Merger
On July 25, 2002, the Trustees of Morgan Stanley High Income Advantage Trust
("HIAT"), Morgan Stanley High Income Advantage Trust II ("HIAT II") and Morgan
Stanley High Income Advantage Trust III ("HIAT III") approved plans of
reorganization whereby HIAT, HIAT II and HIAT III would be merged into the Fund.
The plans of reorganization are subject to the consent of HIAT's, HIAT II's and
HIAT III's shareholders at separate meetings to be held on December 10, 2002. If
approved, the assets of HIAT, HIAT II and HIAT III would be combined with the
assets of the Fund and shareholders of HIAT, HIAT II and HIAT III would become
Class D shareholders of the Fund, receiving Class D shares of the Fund equal to
the value of their holdings in HIAT, HIAT II and HIAT III, respectively.

INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Directors of
Morgan Stanley High Yield Securities Inc.:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley High Yield Securities Inc. (the "Fund"), including the portfolio of
investments, as of August 31, 2002, and the related statements of operations for
the year then ended and changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of August 31, 2002, by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Morgan
Stanley High Yield Securities Inc. as of August 31, 2002, 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 five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

HIGH YIELD SECURITIES

ANNUAL REPORT
AUGUST 31, 2002









Morgan Stanley High Income Advantage Trust III
LETTER TO THE SHAREHOLDERS - JULY 31, 2002

Dear Shareholder:
After the sharp decline in September 2002, the high-yield market bounced back
over the next seven months. The signs of potential economic recovery early in
2002 and strong flows into the high-yield asset class contributed to the
improved tone of the market. However, the high-yield market weakened again
during the balance of the review period as the economy slowed and accounting
scandals at WorldCom and other companies shocked market participants. WorldCom
reported that it had misclassified nearly $3.9 billion in costs. This
announcement caused the market to fall significantly in late June as investor
confidence eroded. Strong inflows into the high-yield asset class -- totaling
nearly $9 billion from January through May -- stopped as investors withdrew
approximately $2 billion in June and July. The size of net redemptions led to
sales by mutual funds and dealers, resulting in lower prices.

On balance, credit spreads in the high-yield market relative to U.S. Treasury
securities widened to historically wide levels. Spreads also widened within the
lower-rated portion of the high-yield market as investors continued to prefer
investments in the relatively higher-quality end of the marketplace. In
addition, bonds in sectors related to telecommunications, cable and utilities
performed poorly as investors continued to be concerned about accounting
scandals and slower economic growth going forward.

Performance and Portfolio Strategy
For the 6-month period ended July 31, 2002, Morgan Stanley High Income Advantage
Trust III's net asset value (NAV) declined from $1.25 per share on January 31,
2002, to $1.07 per share on July 31, 2002. Based on this change, plus the
reinvestment of distributions totaling $0.072 per share, the Trust produced a
total return of -9.18 percent. For the same period, the Trust's market price on
the New York Stock Exchange (NYSE) declined from $1.27 per share on January 31,
2002, to $1.01 per share on July 31, 2002. Based on this change, plus the
reinvestment of distributions, the Trust produced a total return of -15.62
percent.

As noted, the past three years have been one of the most difficult periods for
the high-yield market. As a result of the substantial weakness in the market,
high-yield bond prices have declined sharply and yields have risen over much of
this period. The Trust's positions in the lower-rated portion of the market and
in communications-related industries have been adversely affected. The last
three months represented an extension of these difficulties.

The Trust's allocations in the fixed-line communications, wireless
communications and cable industries contributed to its disappointing performance
during the review period. These industries





Morgan Stanley High Income Advantage Trust III
LETTER TO THE SHAREHOLDERS - JULY 31, 2002 continued

were down by more than 30 percent over the past six months, thereby
underperforming the rest of the high-yield market. Accompanied by slower revenue
growth, higher default rates and many rating downgrades, these factors led
prices lower for most bonds in these industries. Despite the Trust's investments
in a number or these industries having been reduced over the past year,
allocations remained above market weights, thus adversely affecting performance.

Performance was helped by the higher-quality bonds added to the portfolio over
the past year, particularly those in the housing and health-care sectors. These
sectors performed better than most others in the high-yield market. Finally, an
underweighting of the utilities sector helped mitigate losses when this sector
came under pressure as a result of accounting concerns.

Over the course of the fiscal year, the Trust's portfolio management team
continued to reposition the portfolio for the current market environment. New
positions were initiated in many companies, including Starwood Hotels, Venetian,
Intermet, Metaldyne and Foamex.. The team increased the Trust's overall credit
quality by buying BB-rated securities and decreasing exposure to
telecommunications-related industries.

At fiscal year-end the Trust was overweighted toward wireline communications,
cable, wireless communications and media, as well as manufacturing and housing.
Underweighted positions included consumer products and retail. The Trust's
portfolio management team believes that consumer spending is likely to lag the
growth of the overall economy. The Trust also is underweighted toward utilities,
because of accounting concerns, and aerospace, as a result of slow demand.

Looking Ahead
June and July were two of the worst back-to-back months in the history of the
high-yield market. Although the spread widening that has occurred over the last
few months makes the market look attractive, it is uncertain how long it will
take to restore investor confidence. We anticipate that the economy may grow
moderately over the next 18 months. We believe this growth, if realized, should
help corporate balance sheets, which may in turn help to lower defaults among
high-yield issuers.

We also believe that the high-yield market may benefit from a structural shift
in its makeup that has occurred over the past year. One of the greatest excesses
of the late 1990s occurred when more and more lower-quality companies were able
to tap the high-yield market for financing. This wave of lower-quality companies
helped drag down the market's overall credit quality and was a large contributor
to the climbing default rates of the past two years. In our view, this trend

Morgan Stanley High Income Advantage Trust III
LETTER TO THE SHAREHOLDERS - JULY 31, 2002 continued

has reversed in the past year as lower-quality companies have been all but shut
out of the market for new issuance. We anticipate that this shift upward in
quality should also help reduce broader market default rates from their recent
elevated levels back to their historical averages.

Plan of Reorganization
On July 25, 2002, the Board of Trustees of the Trust and the Board of Directors
of Morgan Stanley High Yield Securities approved a proposed plan of
reorganization of the Trust into Morgan Stanley High Yield Securities, an
open-end investment company.

Pursuant to an Agreement and Plan of Reorganization, substantially all the
assets of the Trust would be combined with the assets of Morgan Stanley High
Yield Securities, effectively open-ending the Trust. Shareholders of the Trust
would receive Class D shares of Morgan Stanley High Yield Securities with a
value equal to the net asset value of their respective holdings in the Trust. If
shareholders of the Trust approve the Agreement and Plan of Reorganization, they
would become Class D shareholders of Morgan Stanley High Yield Securities and
the shares of the Trust will no longer be listed or traded on the New York Stock
Exchange. The approval of shareholders of Morgan Stanley High Yield Securities
is not required.

The Agreement and Plan of Reorganization will be submitted to shareholders of
the Trust at a Special Meeting presently scheduled to take place in December
2002. A proxy statement formally detailing the Agreement and Plan of
Reorganization will be mailed to shareholders in September. Morgan Stanley High
Income Advantage Trust III and Morgan Stanley High Yield Securities are managed
by Morgan Stanley Investment Advisors Inc.'s High Yield team.

We would like to remind you that the Trustees have approved a procedure whereby
the Trust may, when appropriate, repurchase shares in the open market or in
privately negotiated transactions at a price not above market value or net asset
value, whichever is lowest at the time of purchase.

Morgan Stanley High Income Advantage Trust III
NOTES TO FINANCIAL STATEMENTS - JULY 31, 2002 (UNAUDITED)

1. Organization and Accounting Policies
Morgan Stanley High Income Advantage Trust III (the "Trust") is registered under
the Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Trust'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 Trust
seeks to achieve its objective by investing primarily in lower-rated fixed
income securities. The Trust was organized as a Massachusetts business trust on
November 23, 1988 and commenced operations on February 28, 1989.

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, Nasdaq, or other exchange is valued at its
latest sale price, prior to the time when assets are valued; if there were no
sales that day, the security is valued at the latest bid price (in cases where
securities are traded on more than one exchange; the securities are valued on
the exchange designated as the primary market pursuant to procedures adopted by
the Trustees); (2) all other portfolio securities for which over-the-counter
market quotations are readily available are valued at the latest available bid
price; (3) when market quotations are not readily available, including
circumstances under which it is determined by Morgan Stanley Investment Advisors
Inc. (the "Investment Manager") that sale or bid prices are not reflective of a
security's market value, portfolio securities are valued at their fair value as
determined in good faith under procedures established by and under the general
supervision of the Trustees; (4) certain of the Trust's portfolio securities may
be valued by an outside pricing service approved by the Trustees. The pricing
service may utilize a matrix system incorporating security quality, maturity and
coupon as the evaluation model parameters, and/or research and evaluations by
its staff, including review of broker-dealer market price quotations, if
available, in determining what it believes is the fair valuation of the
portfolio securities valued by such pricing service; and (5) short-term debt
securities having a maturity date of more than sixty days at time of purchase
are valued on a mark-to-market basis until sixty days prior to maturity and
thereafter at amortized cost based on their value on the 61st day. Short-term
debt securities having a maturity date of sixty days or less at the time of
purchase are valued at amortized cost.

Morgan Stanley High Income Advantage Trust III
NOTES TO FINANCIAL STATEMENTS - JULY 31, 2002 (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.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily except where collection
is not expected.

C. Joint Repurchase Agreement Account -- Pursuant to an Exemptive Order issued
by the Securities and Exchange Commission, the Trust, along with other
affiliated entities managed by the Investment Manager, may transfer uninvested
cash balances into one or more joint repurchase agreement accounts. These
balances are invested in one or more repurchase agreements and are
collateralized by cash, or U.S. Treasury or federal agency obligations.

D. Federal Income Tax Status -- It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

E. Dividends and Distributions to Shareholders -- The Trust records dividends
and distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.

2. Investment Management Agreement
Pursuant to an Investment Management Agreement, the Trust pays the Investment
Manager a management fee, calculated weekly and payable monthly, by applying the
following annual rates to the Trust's weekly net assets: 0.75% to the portion of
weekly net assets not exceeding $250 million; 0.60% to the portion of weekly net
assets exceeding $250 million but not exceeding $500 million; 0.50% to the
portion of weekly net assets exceeding $500 million but

not exceeding $750 million; 0.40% to the portion of weekly net assets exceeding
$750 million but not exceeding $1 billion; and 0.30% to the portion of weekly
net assets exceeding $1 billion.

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 July 31, 2002 aggregated
$3,495,926 and $3,779,459, respectively.

Morgan Stanley Trust, an affiliate of the Investment Manager, is the Trust's
transfer agent. At July 31, 2002, the Trust had transfer agent fees and expenses
payable of approximately $5,000.

6. Federal Income Tax Status
At January 31, 2002, the Trust had a net capital loss carryover of approximately
$40,649,000, which may be used to offset future capital gains to the extent
provided by regulations which is available through January 31 of the following
years:

 $10,665  $4,258   $3,007   $5,910   $1,633   $1,867   $2,195   $11,114
 =======  ======   ======   ======   ======   ======   ======   =======

Capital losses incurred after October 31 ("post-October losses") within the
taxable year are deemed to arise on the first business day of the Trust's next
taxable year. The Trust incurred and will elect to defer net capital losses of
approximately $1,198,000 during fiscal 2002.

As of January 31, 2002, the Trust had temporary book/tax differences primarily
attributable to post-October losses and book amortization of discount on debt
securities and interest on bonds in default.

7. Litigation
On August 29, 2001, a purported class action complaint was filed in the United
States District Court for the Southern District of New York on behalf of
investors in Morgan Stanley High Income Advantage Trust III alleging that the
Trust, its investment advisor and certain of its officers violated the
Investment Company Act of 1940 by deviating from a fundamental investment
restriction by purportedly investing over 25% of its assets in a single
industry. On September 24, 2002, the Court dismissed the complaint with
prejudice.

8. Subsequent Event -- Merger
On July 25, 2002, the Board of Trustees of the Trust and Morgan Stanley High
Yield Securities Inc. ("High Yield") approved a plan of reorganization whereby
the Trust would be merged into High Yield. The Plan of reorganization is subject
to the consent of the Trust's shareholders at a meeting to be held on December
10, 2002. If approved, the assets of the Trust would be combined with the assets
of High Yield and shareholders of the Trust would become Class D shareholders of
High Yield, receiving Class D shares of High Yield equal to the value of their
holdings in the Trust.

Morgan Stanley High Income Advantage Trust III
LETTER TO THE SHAREHOLDERS - JANUARY 31, 2002

Dear Shareholder:

The 12-month period ended January 31, 2002, was a highly volatile one for the
high-yield market, especially after the terrorist attacks of September 11. These
events and the subsequent war on terrorism had a profound effect on the outlook
for the economy and the financial markets. Despite a 50-basis-point reduction in
the federal funds rate, a flight to quality pushed high-yield security prices
sharply lower. Airlines, the lodging and insurance industries, and the
telecommunications and cable industries experienced some of the sharpest price
declines in the marketplace. Even industries that held up relatively well, such
as food, drugs, utilities and energy, experienced price declines. The high-yield
market recovered somewhat in October and November but softened again in
December.

Credit spreads in the high-yield market relative to U.S. Treasury securities
remain at historically wide levels and came very close to reaching an all-time
peak in September. The spreads remained particularly wide within the lower-rated
portion of the market as investors continued to prefer the relatively higher
quality end of the market.

Performance and Portfolio Strategy

For the 12-month period ended January 31, 2002, Morgan Stanley High Income
Advantage Trust III produced a total return of -38.48 percent, based on a change
in net asset value (NAV) and reinvestment of dividends totaling $0.291 per
share. For the same period, the Trust's total return was -63.16 percent, based
on a change in its market price on the New York Stock Exchange (NYSE) and
reinvestment of dividends.

During the fiscal year, the Trust instituted several important changes to its
dividend policy. First, in May, the Trust lowered its income dividend from
$0.035 per share to $0.017 per share. The Trust's January 2002, income dividend
was lowered to $0.012 per share. In addition, beginning with that dividend, the
Trust moved from paying a fixed dividend rate to one that fluctuates with the
amount of income earned by the Trust. We believe that adopting a fluctuating
dividend policy will provide the Trust with greater flexibility. Should the
Trust experience additional defaults, the dividend amount will be lower.
Conversely, should the economy improve, defaults stabilize and income levels
increase, the Trust's dividend rate could rise.

As stated in previous communications, the past three years have been one of the
most difficult periods for the high-yield market, with such events as the
September economic shock and recent accounting scandals only exacerbating the
problem. As a result of the substantial weakness in the market, we have seen
high-yield bond prices decline sharply and yields rise over much of this period.
The past 12 months remained particularly difficult for many companies in the

telecommunications sector and the many industries within that sector as poor
earnings and lower revenues pushed the sector lower.

The telecommunications sector experienced many rating downgrades and an elevated
default rate during this period, which resulted in security price declines for
most of the sector's bonds. Fixed-line telecommunications was the
worst-performing sector during the past 12 months, down more than 40 percent.
Consequently, allocations in the fixed-line communications and wireless
communications industries accounted for much of the Trust's disappointing
performance. The Trust's positions in lower-rated credits also adversely
affected overall performance.

Over the past year, the Trust's portfolio management team continued to
reposition the portfolio for the current market environment. The team reduced
positions in telecommunications and related industries but increased the average
credit rating for securities in the Trust's portfolio. The Trust continues to
maintain constructive positions in the wireline and wireless communications,
cable and media industries. The Trust initiated positions in more than 60 new
companies, including Collins and Aikman, Stone Energy, Allied Waste, Chesapeake
Energy, Schuler Homes, Salem Communications, Healthnet, PRIMEDIA, Quebecor,
Nextmedia and Beazer Homes. The Trust eliminated positions in many companies
such as Brill Media, Envirodyne, Neff, Friendly's, Windemere, Sabreliner, and
James Cable.

Looking Ahead

The events of September 11 had a negative impact on the economy over the past
six months. We feel, however, that the current spread of the high-yield market
appears to be pricing in a more prolonged downturn with an extended period of
higher default rates than would be consistent with historical experience. We
consider that the monetary and fiscal policy moves that have already been
implemented are likely to bring the economy back to more normal growth levels,
which could lead to a recovery in the high-yield market. The Trust's portfolio
is positioned to participate in any potential recovery.

We appreciate your ongoing support of Morgan Stanley High Income Advantage Trust
III and look forward to continuing to serve your investment needs.

Very truly yours,

Morgan Stanley High Income Advantage Trust III
NOTES TO FINANCIAL STATEMENTS - JANUARY 31, 2002

1. Organization and Accounting Policies

Morgan Stanley High Income Advantage Trust III (the "Trust"), formerly Morgan
Stanley Dean Witter High Income Advantage Trust III, is registered under the
Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Trust'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 Trust
seeks to achieve its objective by investing primarily in lower-rated fixed
income securities. The Trust was organized as a Massachusetts business trust on
November 23, 1988 and commenced operations on February 28, 1989.

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, NASDAQ, or other exchange is valued at its
latest sale price, prior to the time when assets are valued; if there were no
sales that day, the security is valued at the latest bid price (in cases where
securities are traded on more than one exchange; the securities are valued on
the exchange designated as the primary market pursuant to procedures adopted by
the Trustees); (2) all other portfolio securities for which over-the-counter
market quotations are readily available are valued at the latest available bid
price; (3) when market quotations are not readily available, including
circumstances under which it is determined by Morgan Stanley Investment Advisors
Inc. (the "Investment Manager"), formerly Morgan Stanley Dean Witter Advisors
Inc., that sale or bid prices are not reflective of a security's market value,
portfolio securities are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the
Trustees; (4) certain of the Trust's portfolio securities may be valued by an
outside pricing service approved by the Trustees. The pricing service may
utilize a matrix system incorporating security quality, maturity and coupon as
the evaluation model parameters, and/or research and evaluations by its staff,
including review of broker-dealer market price quotations, if available, in
determining what it believes is the fair valuation of the portfolio securities
valued by such pricing service; and (5) short-term debt securities having a
maturity date of more than sixty days at time of purchase are valued on a
mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.

Morgan Stanley High Income Advantage Trust III
NOTES TO FINANCIAL STATEMENTS - JANUARY 31, 2002 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.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily except where collection
is not expected.

C. Joint Repurchase Agreement Account -- Pursuant to an Exemptive Order issued
by the Securities and Exchange Commission, the Trust, along with other
affiliated entities managed by the Investment Manager, may transfer uninvested
cash balances into one or more joint repurchase agreement accounts. These
balances are invested in one or more repurchase agreements for cash, or U.S.
Treasury or federal agency obligations.

D. Federal Income Tax Status -- It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

E. Dividends and Distributions to Shareholders -- The Trust records dividends
and distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.

2. Investment Management Agreement

Pursuant to an Investment Management Agreement, the Trust pays the Investment
Manager a management fee, calculated weekly and payable monthly, by applying the
following annual rates to the Trust's weekly net assets: 0.75% to the portion of
weekly net assets not exceeding $250 million; 0.60% to the portion of weekly net
assets exceeding $250 million but not exceeding $500 million; 0.50% to the
portion of weekly net assets exceeding $500 million but not exceeding $750

6. Federal Income Tax Status

At January 31, 2002, the Trust had a net capital loss carryover of approximately
$40,649,000, which may be used to offset future capital gains to the extent
provided by regulations, which is available through January 31 of the following
years:

Capital losses incurred after October 31 ("post-October" losses) within the
taxable year are deemed to arise on the first business day of the Trust's next
taxable year. The Trust incurred and will elect to defer net capital losses of
approximately $1,198,000 during fiscal 2002.

As of January 31, 2002, the Trust had temporary book/tax differences
attributable to post-October losses, and book amortization of discounts on debt
securities and interest on bonds in default and permanent book/tax differences
attributable to an expired capital loss carryover and tax adjustments on debt
securities sold by the Trust. To reflect reclassifications arising from the
permanent differences, paid-in-capital was charged $3,256,005, dividends in
excess of net investment income was charged $84,916 and accumulated net realized
loss was credited $3,340,921.

7. Change in Accounting Policy

Effective February 1, 2001, the Trust has adopted the provisions of the AICPA
Audit and Accounting Guide for Investment Companies, as revised, related to
premiums and discounts on debt securities. The cumulative effect of this
accounting change had no impact on the net assets of the Trust, but resulted in
a $339,684 increase in the cost of securities and a corresponding increase to
undistributed net investment income based on securities held as of January 31,
2001.

The effect of this change for the year ended January 31, 2002 was to increase
net investment income by $64,494; decrease unrealized depreciation by $20,422;
and increase net realized losses by $84,916. The statement of changes in net
assets and the financial highlights for prior periods have not been restated to
reflect this change.

8. Litigation

On August 29, 2001, a purported class action was filed on behalf of investors in
Morgan Stanley High Income Advantage Trust III alleging that the Trust, its
investment advisor and certain of its officers violated the Investment Company
Act of 1940 by deviating from a fundamental investment restriction by
purportedly investing over 25% of its assets in a single industry. The Trust,
its investment advisor and officers believe the suit to be without merit and
intend to vigorously contest the action.

II. DESCRIPTION OF THE FUND AND ITS INVESTMENTS AND RISKS
- --------------------------------------------------------------------------------

A. CLASSIFICATION

    The Fund is an open-end, diversified management investment company whose
investment objective is to earn a high level of current income. As a secondary
objective, the Fund seeks capital appreciation but only to the extent consistent
with its primary objective.

B. INVESTMENT STRATEGIES AND RISKS

    The following discussion of the Fund's investment strategies and risks
should be read with the sections of the Fund's Prospectus titled "Principal
Investment Strategies," "Principal Risks," "Additional Investment Strategy
Information," and "Additional Risk Information."

    FUTURES TRANSACTIONS.  The Fund may purchase and sell interest rate
contracts that are traded on U.S. and foreign commodity exchanges.

    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.

    Although the terms of future 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 the 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.

    Margin.  If the Fund enters into a futures contract, it is initially
required to deposit an "initial margin" of cash or U.S. government securities or
other liquid portfolio securities ranging from approximately 2% to 5% of the
contract amount. Initial margin requirements are established by the exchanges on
which futures contracts trade and may, from time to time, change. In addition,
brokers may establish margin deposit requirements in excess of those required by
the exchanges.

    Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing of
funds by a broker's client but is, rather, a good faith deposit on the futures
contract which will be returned to the Fund upon the proper termination of the
futures contract. The margin deposits made are marked to market daily and the
Fund may be required to make subsequent deposits of cash or U.S. government
securities or other liquid portfolio securities, called "variation margin,"
which are reflective of price fluctuations in the futures contract.

                                       4


    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 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%.

    Risks of Transactions in Futures Contracts and Related Options.  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.

    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. 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.

    Exchanges also 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 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 on open futures positions. In these 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
hedges its portfolio.

                                       5


    Futures contracts and options thereon which are purchased or sold on foreign
commodities exchanges may have greater price volatility than their U.S.
counterparts. Furthermore, foreign commodities exchanges may be less regulated
and under less governmental scrutiny than U.S. exchanges. Brokerage commissions,
clearing costs and other transaction costs may be higher on foreign exchanges.
Greater margin requirements may limit the Fund's ability to enter into certain
commodity transactions on foreign exchanges. Moreover, differences in clearance
and delivery requirements on foreign exchanges may occasion delays in the
settlement of the Fund's transactions effected on foreign exchanges.

    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in futures or options thereon, the Fund could experience delays
and/or losses in liquidating open positions purchased or sold through the broker
and/or incur a loss of all or part of its margin deposits with the broker.

    If the Fund maintains a short position in a futures contract or has sold a
call option in a futures contract, it will cover this position by holding, in a
segregated account maintained on the books of the Fund, 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, or by holding a call option permitting the Fund to purchase
the same contract at a price no higher than the price at which the short
position was established.

    In addition, if the Fund holds a long position in a futures contract or has
sold a put option on a futures contract, it will hold cash, U.S. government
securities or other liquid portfolio securities equal to the purchase price of
the contract or the exercise price of the put option (less the amount of initial
or variation margin on deposit) in a segregated account maintained on the books
of the Fund. 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.

    OPTIONS.  The Fund may purchase or sell (write) options on debt securities
as a means of achieving additional return or hedging the value of the Fund's
portfolio. The Fund may only buy options 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.

    A call option is a contract that gives the holder of the option the right to
buy from the writer 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 may only write covered call or covered put options listed on
national exchanges. The Fund may not write covered options in an amount
exceeding 20% of the value of the total assets of the Fund. 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 or futures contract
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 a call on the same security or futures contract 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 a put on the same security
or futures contract 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.

                                       6


    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 fund as the option previously
purchased. There can be no assurance that either a closing purchase or sale
transaction on behalf of the Fund can be effected when the Fund so desires.

    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 purchase 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
premiums 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 commission upon the exercise of call options and upon 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.

    MONEY MARKET SECURITIES.  In addition to the money market securities in
which the Fund may otherwise invest, the Fund may invest in various money market
securities for cash management purposes or when assuming a temporary defensive
position, which among others may include commercial paper, bank acceptances,
bank obligations, corporate debt securities, certificates of deposit, U.S.
government securities, obligations of savings institutions and repurchase
agreements. Such securities are limited to:

    U.S. Government Securities.  Obligations issued or guaranteed as to
principal and interest by the United States or its agencies (such as the
Export-Import Bank of the United States, Federal Housing Administration and
Government National Mortgage Association) or its instrumentalities (such as the
Federal Home Loan Bank), including Treasury bills, notes and bonds;

    Bank Obligations.  Obligations (including certificates of deposit, time
deposits and bankers' acceptances) of banks subject to regulation by the U.S.
Government and having total assets of $1 billion or more, and instruments
secured by such obligations, not including obligations of foreign branches of
domestic banks except to the extent below;

    Eurodollar Certificates of Deposit.  Eurodollar certificates of deposit
issued by foreign branches of domestic banks having total assets of $1 billion
or more;

    Obligations of Savings Institutions.  Certificates of deposit of savings
banks and savings and loan associations, having total assets of $1 billion or
more;

    Fully Insured Certificates of Deposit.  Certificates of deposit of banks and
savings institutions, having total assets of less than $1 billion, if the
principal amount of the obligation is federally insured by

                                       7


the Bank Insurance Fund or the Savings Association Insurance Fund (each of which
is administered by the FDIC), limited to $100,000 principal amount per
certificate and to 10% or less of the Fund's total assets in all such
obligations and in all illiquid assets, in the aggregate;

    Commercial Paper.  Commercial paper rated within the two highest grades by
Standard & Poor's Corporation ("S&P") or by Moody's Investors Service, Inc.
("Moody's") or, if not rated, issued by a company having an outstanding debt
issue rated at least AA by S&P or Aa by Moody's; and

    Repurchase Agreements.  The Fund may invest in 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 serving as 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 marked-to-market daily to determine
that the value of the collateral, as specified in the agreement, does not
decrease below the purchase price plus accrued interest. If such decrease
occurs, additional collateral will be requested and, when received, added to the
account to maintain full collateralization. The Fund will accrue interest from
the institution until the time when the repurchase is to occur. Although this
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 approved by the
Directors 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. 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.

    MUNICIPAL OBLIGATIONS.  The Fund may invest up to 10% of its total assets in
municipal obligations that pay interest exempt from federal income tax.
Municipal obligations are securities issued by state and local governments and
regional government authorities. These securities typically are "general
obligation" or "revenue" bonds, notes or commercial paper. General obligation
securities are secured by the issuer's faith and credit, as well as its taxing
power, for payment of principal and interest. Revenue bonds, however, are
generally payable from a specific revenue source. They are issued to fund a wide
variety of public and private projects in sectors such as transportation,
education and industrial development. Included within the revenue bonds category
are participations in lease obligations and installment contracts of
municipalities.

    PUBLIC UTILITIES.  The Fund's investments in the utilities industry are
impacted by risks particular to that industry. Changing regulation constitutes
one of the key industry-specific risks for the Fund, especially with respect to
its investments in traditionally regulated public utilities and partially
regulated utility companies. State and other regulators monitor and control
utility revenues and costs, and therefore may limit utility profits. Regulatory
authorities also may restrict a company's access to new markets, thereby
diminishing the company's long-term prospects.

    LENDING PORTFOLIO SECURITIES.  The Fund may lend its portfolio securities to
brokers, dealers and other financial institutions, provided that the loans are
callable at any time by the Fund, 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 100% of the market value, determined
daily, of the loaned securities. The advantage of these loans is that the Fund
continues to receive the income on the

                                       8


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 more than 25% of the value of its total assets.

    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.

    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 the rights
if the matters involved would have a material effect on the Fund's investment in
the 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.  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 these 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 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, their value may be more
or less than the purchase or sale price. 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 its net
asset value. The Fund will also establish a segregated account on the Fund's
books 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.

    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 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
that time, the Fund will record the transaction and, in determining its net
asset value, will reflect the value of the security daily. At that time, the
Fund will also establish a segregated account on the Fund's books in which it
will maintain cash or cash equivalents or other liquid portfolio securities
equal in value to recognized commitments for such securities.

    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. 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 sale.

    PRIVATE PLACEMENTS.  The Fund may invest up to 15% of its net assets in
securities which are subject to restrictions on resale because they have not
been registered under the Securities Act of 1933

                                       9


(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 these 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 the securities for resale and the risk of substantial delays in
effecting the registration.

    Rule 144A permits the Fund to sell restricted securities to qualified
institutional buyers without limitation. The Investment Manager, pursuant to
procedures adopted by the Directors, 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," the security will not be included within
the category "illiquid securities," which 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.

    WARRANTS AND SUBSCRIPTION RIGHTS.  The Fund may acquire warrants and
subscription rights attached to other securities. A warrant is, in effect, an
option to purchase equity securities at a specific price, generally valid for a
specific period of time, and has no voting rights, pays no dividends and has no
rights with respect to the corporation issuing it.

    A subscription right is a privilege granted to existing shareholders of a
corporation to subscribe to shares of a new issue of common stock before it is
offered to the public. A subscription right normally has a life of two to four
weeks and a subscription price lower than the current market value of the common
stock.

C. FUND POLICIES/INVESTMENT RESTRICTIONS

    The investment objective, policies and restrictions listed below have been
adopted by the Fund as fundamental policies. Under the Investment Company Act of
1940, as amended (the "Investment Company Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund. The Investment Company Act defines a majority 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. For
purposes of the following restrictions: (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 will:

         1. As a primary objective, seek to earn a high level of current income.

         2. As a secondary objective, seek capital appreciation but only to the
    extent consistent with its primary objective.

    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.

                                       10


         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.

         6. Make short sales of securities.

         7. Purchase securities on margin, except for such short-term loans as
    are necessary for the clearance of purchases of portfolio securities.

         8. 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 permitted borrowings. 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.

         9. Engage in the underwriting of securities except insofar as the Fund
    may be deemed an underwriter under the Securities Act in disposing of a
    portfolio security.

         10. 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.

         11. Purchase or sell commodities except that the Fund may purchase
    financial futures contracts and related options.

         12. Make loans of money or securities, except: (a) the purchase of debt
    obligations; (b) investment in repurchase agreements; or (c) by lending its
    portfolio securities.

         13. 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.

         14. Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets.

III. MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------

A. BOARD OF DIRECTORS

    The Board of Directors of the Fund oversees the management of the Fund but
does not itself manage the Fund. The Directors review various services provided
by or under the direction of the Investment Manager to ensure that the Fund's
general investment policies and programs are properly carried out. The Directors
also conduct their review to ensure that administrative services are provided to
the Fund in a satisfactory manner.

    Under state law, the duties of the Directors are generally characterized as
a duty of loyalty and a duty of care. The duty of loyalty requires a Director to
exercise his or her powers in the interest of the Fund and not the Director's
own interest or the interest of another person or organization. A Director
satisfies his or her duty of care by acting in good faith with the care of an
ordinarily prudent person and in a manner the Director reasonably believes to be
in the best interest of the Fund and its shareholders.

B. MANAGEMENT INFORMATION


    DIRECTORS AND OFFICERS.  The Board of the Fund consists of eight (8)
Directors. These same individuals also serve as directors or trustees for all of
the Morgan Stanley Funds. Five Directors have no affiliation or business
connection with the Investment Manager or any of its affiliated persons and do
not own any stock or other securities issued by the Investment Manager's parent
company, Morgan Stanley. These are the "non-interested" or "independent"
Directors. The other three Directors (the "Management Directors") are affiliated
with the Investment Manager.

    The Independent Directors of the Fund, their term of office and length of
time served, their principal business occupations during the past five years,
the number of portfolios in the Fund Complex (defined below) overseen by each
Independent Director (as of December 31, 2001) and other directorships, if any,
held by the Director, are shown below. The Fund Complex includes all open- and
closed-end funds (including all of their portfolios) advised by Morgan Stanley
Investment Advisors Inc. and any funds that have an investment advisor that is
an affiliated person of Morgan Stanley Investment Advisors Inc. (including, but
not limited to, Morgan Stanley Investment Management Inc., Morgan Stanley
Investments LP and Van Kampen Asset Management Inc.).

    As to each independent Director and his immediate family members, no person
owned beneficially or of record securities in an investment advisor or principal
underwriter of the Fund, or a person (other than a registered investment
company) directly or indirectly controlling, controlled by or under common
control with an investment advisor or principal underwriter of the Fund.

    INDEPENDENT DIRECTORS/TRUSTEES AND THE COMMITTEES.  Law and regulation
establish both general guidelines and specific duties for the independent
directors/trustees. The Morgan Stanley Funds seek as independent
directors/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.
All of the independent directors/trustees serve as members of the Audit
Committee. In addition, six of the directors/trustees, including all of the
independent directors/trustees, serve as members of the Derivatives Committee
and three directors/trustees including two independent directors/trustees serve
as members of the Insurance Committee.

    The independent directors/trustees are 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 directors/trustees are required to select and nominate individuals
to fill any independent director/trustee vacancy on the board of any Fund that
has a Rule 12b-1 plan of distribution. Most of the Morgan Stanley Funds have a
Rule 12b-1 plan.

    The Audit Committee is charged with recommending to the full board the
engagement or discharge of the Fund's independent auditors; directing
investigations into matters within the scope of the independent auditors'
duties, including the power to retain outside specialists; reviewing with the
independent

                                       16


auditors the audit plan and results of the auditing engagement; approving
professional services provided by the independent auditors and other accounting
firms prior to the performance of the services; reviewing the independence of
the independent auditors; 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. The Audit Committee
currently consists of Messrs. Johnson, Bozic, Hedien, Garn and Nugent. During
the Fund's fiscal year ended August 31, 2002, the Audit Committee held 10
meetings.


    The board of each Fund has a Derivatives Committee to approve parameters for
and monitor the activities of the Fund with respect to derivative investments,
if any, made by the Fund. The Derivatives Committee currently consists of Mr.
Fiumefreddo and all of the Independent Directors of the Fund. During the Fund's
fiscal year ended August 31, 2002, the Derivatives Committee held three
meetings.


    Finally, the board of each Fund has formed an Insurance Committee to review
and monitor the insurance coverage maintained by the Fund. The Insurance
Committee currently consists of Messrs. Nugent, Fiumefreddo and Hedien. During
the Fund's fiscal year ended August 31, 2002, the Insurance Committee held one
meeting.

    ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT DIRECTORS/TRUSTEES FOR
ALL MORGAN STANLEY FUNDS.  The independent directors/trustees and the Funds'
management believe that having the same independent directors/trustees for each
of the Morgan Stanley Funds avoids the duplication of effort that would arise
from having different groups of individuals serving as independent directors/
trustees for each of the Funds or even of sub-groups of Funds. They believe that
having the same individuals serve as independent directors/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 directors/trustees
arriving at conflicting decisions regarding operations and management of the
Funds and avoids the cost and confusion that would likely ensue. Finally, having
the same independent directors/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 directors/ trustees, of the caliber, experience and
business acumen of the individuals who serve as independent directors/trustees
of the Morgan Stanley Funds.

    DIRECTOR AND OFFICER INDEMNIFICATION.  The Fund's By-Laws provides that no
Director, officer, employee or agent of the Fund is liable to the Fund or to a
shareholder, nor is any Director, officer, employee or agent liable to any third
persons in connection with the affairs of the Fund, except as such liability may
arise from his/her or its own bad faith, willful misfeasance, gross negligence
or reckless disregard of his/her or its duties. It also provides that all third
persons shall look solely to the Fund property for satisfaction of claims
arising in connection with the affairs of the Fund. With the exceptions stated,
the By-Laws provides that a Director, officer, employee or agent is entitled to
be indemnified against all liability in connection with the affairs of the Fund.

C. COMPENSATION

    The Fund pays each Independent Director an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Directors, the Independent
Directors or Committees of the Board of Directors attended by the Director (the
Fund pays the Chairman of the Audit Committee an additional annual fee of $750,
and the Chairmen of the Derivatives and Insurance Committees additional annual
fees of $500). If a Board meeting and a meeting of the Independent Directors or
a Committee meeting (except an Audit Committee meeting), or a meeting of the
Independent Directors and/or more than one Committee meeting (except an Audit
Committee meeting), take place on a single day, the Directors are paid a single
meeting fee by the Fund. 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 for their services as Director. The Fund
pays Mr. Fiumefreddo an annual fee for his service as Chairman of the Board and
for administrative services provided to the Board of Directors.

    As of the date of this Statement of Additional Information, 51 of the Morgan
Stanley Funds, including the Fund, have adopted a retirement program under which
an independent director/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/trustee of any Morgan Stanley 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 for the remainder of his or her life, an annual retirement benefit
(the "Regular Benefit") equal to 30.22% of his or her Eligible Compensation plus
0.5036667% of such Eligible Compensation for each full month of service as an
independent director/ trustee of any Adopting Fund in excess of five years up to
a maximum of 60.44% 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

- ------------------------
(1) An Eligible Director may elect alternative payments of his or her retirement
    benefits based upon the combined life expectancy of the Eligible Director
    and his or her spouse on the date of such Eligible Director's retirement. In
    addition, the Eligible Director may elect that the surviving spouse's
    periodic payment of benefits will be equal to a lower percentage of the
    periodic amount when both spouses were alive. The amount estimated to be
    payable under this method, through the remainder of the later of the lives
    of the Eligible Director and spouse, will be the actuarial equivalent of the
    Regular Benefit.

year period prior to the date of the Eligible Director's retirement. Benefits
under the retirement program are accrued as expenses on the books of the
Adopting Funds. Such benefits 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,
2002 and by the 52 Morgan Stanley Funds (including the Fund) for the calendar
year ended December 31, 2001, and the estimated retirement benefits for the
Independent Directors, to commence upon their retirement, from the Fund as of
August 31, 2002 and from the 52 Morgan Stanley Funds as of calendar year ended
December 31, 2001. For the calendar year ended December 31, 2001, no retirement
benefits were accrued to the Independent Trustees from any other funds in the
Fund Complex.

V. INVESTMENT MANAGEMENT AND OTHER SERVICES
- --------------------------------------------------------------------------------

A. INVESTMENT MANAGER

    The Investment Manager to the Fund is Morgan Stanley Investment Advisors
Inc., a Delaware corporation, whose address is 1221 Avenue of the Americas, New
York, NY 10020. The Investment Manager is a wholly-owned subsidiary of Morgan
Stanley, a Delaware corporation. Morgan Stanley is a preeminent global financial
services firm that maintains leading market positions in each of its three
primary businesses: securities, asset management and credit services.

    Pursuant to an Investment Management Agreement (the "Management Agreement")
with the Investment Manager, the Fund has retained the Investment Manager to
provide administrative services and manage the investment of the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. 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% 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


                                       19


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. The management fee is
allocated among the Classes pro rata based on the net assets of the Fund
attributable to each Class. For the fiscal years ended August 31, 2000, 2001 and
2002, the Investment Manager accrued total compensation under the Management
Agreement in the amounts of $8,439,728, $5,350,108 and $3,258,237, respectively.

    The Investment Manager has retained its wholly-owned subsidiary, Morgan
Stanley Services, to perform administrative services for the Fund.

    In approving the Management Agreement, the Board of Directors, including the
Independent Directors, considered the nature, quality and scope of the services
provided by the Investment Manager, the performance, fees and expenses of the
Fund compared to other similar investment companies, the Investment Manager's
expenses in providing the services, the profitability of the Investment Manager
and its affiliated companies and other benefits they derive from their
relationship with the Fund and the extent to which economies of scale are shared
with the Fund. The Independent Directors met with and reviewed reports from
third parties about the foregoing factors and changes, if any, in such items
since the preceding year's deliberations. The Independent Directors noted their
confidence in the capability and integrity of the senior management and staff of
the Investment Manager and the financial strength of the Investment Manager and
its affiliated companies. The Independent Directors weighed the foregoing
factors in light of the advice given to them by their legal counsel as to the
law applicable to the review of investment advisory contracts. Based upon its
review, the Board of Directors, including all of the Independent Directors,
determined, in the exercise of its business judgment, that approval of the
Management Agreement was in the best interests of the Fund and its shareholders.

B. PRINCIPAL UNDERWRITER

    The Fund's principal underwriter is the Distributor (which has the same
address as the Investment Manager). In this capacity, the Fund's shares are
distributed by the Distributor. The Distributor has entered into a selected
dealer agreement with Morgan Stanley DW, which through its own sales
organization sells shares of the Fund. In addition, the Distributor may enter
into similar agreements with other selected broker-dealers. The Distributor, a
Delaware corporation, is a wholly-owned subsidiary of Morgan Stanley.

    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. These expenses include the payment of commissions
for sales of the Fund's shares and incentive compensation to Financial Advisors,
the cost of educational and/or business-related trips, and educational and/or
promotional and business-related expenses. 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 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. 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.

C. SERVICES PROVIDED BY THE INVESTMENT MANAGER

    The Investment Manager manages 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

                                       20


the 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 Management 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, the office space, facilities,
equipment, clerical help, bookkeeping and certain legal services as the Fund may
reasonably require in the conduct of its business, including the preparation of
prospectuses, proxy statements and reports required to be filed with federal and
state securities commissions (except insofar as the participation or assistance
of independent auditors and attorneys is, in the opinion of the Investment
Manager, necessary or desirable). The Investment Manager also bears the cost of
telephone service, heat, light, power and other utilities provided to the Fund.

    Expenses not expressly assumed by the Investment Manager under the
Management Agreement or by the Distributor, will be paid by the Fund. These
expenses will be allocated among the four Classes of shares pro rata based on
the net assets of the Fund attributable to each Class, except as described
below. Such expenses include, but are not limited to: expenses of the Plan of
Distribution pursuant to Rule 12b-1; charges and expenses of any registrar,
custodian, stock transfer and dividend disbursing agent; brokerage commissions;
taxes; engraving and printing 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 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 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 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); fees and expenses of the Fund's independent auditors; 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.

    The Management Agreement provides that in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, the Investment Manager is not liable to the Fund or any
of its investors for any act or omission by the Investment Manager or for any
losses sustained by the Fund or its investors.

    The Management Agreement will remain in effect from year to year, provided
continuance of the Management Agreement is approved at least annually by the
vote of the holders of a majority, as defined in the Investment Company Act, of
the outstanding shares of the Fund, or by the Directors, including a majority of
the Independent Directors; provided that in either event such continuance is
approved annually by the vote of a majority of the Directors, including a
majority of the Independent Directors.

D. DEALER REALLOWANCES

    Upon notice to selected broker-dealers, the Distributor may reallow up to
the full applicable front-end sales charge 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.

                                       21


E. RULE 12b-1 PLAN

    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Investment Company Act (the "Plan") pursuant to which each Class, other than
Class D, pays the Distributor compensation accrued daily and payable monthly at
the following maximum annual rates: 0.25%, 0.75% and 0.85% of the average daily
net assets of Class A, Class B and Class C, respectively.

    The Distributor also receives the proceeds of front-end sales charges
("FSCs") and of contingent deferred sales charges ("CDSCs") imposed on certain
redemptions of shares, which are separate and apart from payments made pursuant
to the Plan. The Distributor has informed the Fund that it and/or Morgan Stanley
DW received the proceeds of CDSCs and FSCs, for the last three fiscal years
ended August 31, in approximate amounts as provided in the table below (the
Distributor did not retain any of these amounts).



                                 2002                   2001                   2000
                         --------------------   --------------------   --------------------
                                                              
Class A................  FSCs:(1)  $  135,390   FSCs:(1)  $  217,448   FSCs:(1)  $  187,035
                          CDSCs:   $   26,842    CDSCs:   $   12,759    CDSCs:   $   26,734
Class B................  CDSCs:    $1,519,542   CDSCs:    $3,170,758   CDSCs:    $4,887,041
Class C................  CDSCs:    $   29,347   CDSCs:    $   61,850   CDSCs:    $   86,304


- ------------------------
(1) FSCs apply to Class A only.

    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 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 Rules of the Association.

    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. During the fiscal year ended August 31, 2002,
Class A, Class B and Class C shares of the Fund accrued amounts payable to the
Distributor under the Plan of $48,012, $3,747,816 and $349,455, respectively,
which amounts are equal to 0.18%, 0.75% and 0.85% of the average daily net
assets of Class A, Class B and Class C, respectively.

    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, each with a different distribution arrangement.

    With respect to Class A shares, Morgan Stanley DW compensates its Financial
Advisors by paying them, from proceeds of the FSC, 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 Financial Advisors 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 employer-sponsored employee benefit
plans, whether or not qualified under the Internal Revenue Code, for which
(i) the Transfer Agent serves as Trustee, (ii) Morgan Stanley's Retirement Plan
Services serves as recordkeeper pursuant to a written Recordkeeping Services
Agreement or (iii) an entity independent from Morgan Stanley serves as
recordkeeper under an alliance or similar agreement with Morgan Stanley's
Retirement Plan Services ("Morgan Stanley Eligible Plans"), the Investment
Manager compensates Financial Advisors by paying them, from its own funds, a
gross sales credit of 1.0% of the amount sold.

    With respect to Class B shares, Morgan Stanley DW compensates its Financial
Advisors by paying them, from its own funds, commissions for the sale of
Class B shares, currently a gross sales credit of up

                                       22


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 (not including reinvested dividends or distributions) of the amount sold
in all cases. In the case of Class B shares purchased by Morgan Stanley Eligible
Plans, Morgan Stanley DW compensates its Financial Advisors by paying them, from
its own funds, a gross sales credit of 3.0% of the amount sold.

    With respect to Class C shares, Morgan Stanley DW compensates its Financial
Advisors 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 up to 0.85% of the current value of
the respective accounts for which they are the Financial Advisors of record.

    With respect to Class D shares other than shares held by participants in the
Investment Manager's mutual fund asset allocation program and in the Morgan
Stanley Choice Program, the Investment Manager compensates Morgan Stanley DW's
Financial Advisors 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 Morgan Stanley DW's Financial Advisors by paying them,
from its own funds, an annual residual commission, currently up to 0.10% of the
current value of the respective accounts for which they are the Financial
Advisors of record (not including accounts of participants in the Investment
Manager's mutual fund asset allocation program and the Morgan Stanley Choice
Program).

    The gross sales credit is a charge which reflects commissions paid by Morgan
Stanley DW to its Financial Advisors and Morgan Stanley DW's Fund-associated
distribution-related expenses, including sales compensation, and overhead and
other branch office distribution-related expenses including (a) the expenses of
operating Morgan Stanley DW'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 Investment Manager pays a retention fee to Financial Advisors at an
annual rate of 0.05% of the value of shares of the Fund held for at least one
year. Shares purchased through the reinvestment of dividends will be eligible
for a retention fee, provided that such dividends were earned on shares
otherwise eligible for a retention fee payment. Shares owned in variable
annuities, closed-end fund shares and shares held in 401(k) plans where the
Transfer Agent or Morgan Stanley's Retirement Plan Services is either
recordkeeper or trustee are not eligible for a retention fee.

    The retention fees are paid by the Investment Manager from its own assets,
which may include profits from investment management fees payable under the
Management Agreement, as well as from borrowed funds.

    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").
These expenses may include the cost of Fund-related educational and/or
business-related trips or payment of Fund-related educational and/or promotional
expenses of Financial Advisors. For example, the Distributor has implemented a
compensation program available only to Financial Advisors meeting specified
criteria under which certain marketing and/or promotional expenses of those
Financial Advisors are paid by the Distributor out of compensation it receives
under the Plan. 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

                                       23


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 Financial Advisors and other authorized financial
representatives, such amounts shall be determined at the beginning of each
calendar quarter by the Directors, including, a majority of the Independent
Directors. Expenses representing the service fee (for Class A) or a gross sales
credit or a residual to Financial Advisors and other authorized financial
representatives (for Class C) may be reimbursed without prior determination. In
the event that the Distributor proposes that monies shall be reimbursed for
other than such expenses, then in making quarterly determinations of the amounts
that may be reimbursed by the Fund, the Distributor will provide and the
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.

    Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended August 31, 2002 to the Distributor. The
Distributor and Morgan Stanley DW estimate that they have spent, pursuant to the
Plan, $124,910,663 on behalf of Class B since the inception of the Plan. It is
estimated that this amount was spent in approximately the following ways:
(i) 4.08% ($5,098,452)--advertising and promotional expenses; (ii) 0.05%
($58,266)--printing of prospectuses for distribution to other than current
shareholders; and (iii) 95.87% ($119,753,945)--other expenses, including the
gross sales credit and the carrying charge, of which 9.99% ($11,958,129)
represents carrying charges, 24.55% ($29,394,898) represents commission credits
to Morgan Stanley DW branch offices and other selected broker-dealers for
payments of commissions to Financial Advisors and other authorized financial
representatives, 34.74% ($41,607,270) represents overhead and other branch
office distribution-related expenses, and 30.72% ($36,793,648) represents excess
distribution expenses of Dean Witter High Income Securities, the net assets of
which were combined with those of the Fund on November 10, 1997 pursuant to an
Agreement and Plan of Reorganization. The amount accrued by Class A and a
portion of the amounts accrued by Class C under the Plan during the fiscal year
ended August 31, 2002 were service fees. The remainder of the amounts accrued by
Class C were for expenses which relate to compensation of sales personnel and
associated overhead expenses.

    In the case of Class B shares, at any given time, the expenses 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 CDSCs
paid by investors upon redemption of 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. The Distributor has advised the Fund that in
the case of Class B shares the excess distribution expenses, including the
carrying charge designed to approximate the opportunity costs incurred by Morgan
Stanley DW which arise from it having advanced monies without having received
the amount of any sales charges imposed at the time of sale of the Fund's
Class B shares, totaled $60,068,745 as of August 31, 2002, which was equal to
16.17% of the net assets of Class B on such date. 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

                                       24


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 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 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 Morgan Stanley Financial Advisors and other
authorized financial representatives at the time of sale may be reimbursed in
the subsequent calendar year. The Distributor has advised the Fund that
unreimbursed expenses representing a gross sales commission credited to Morgan
Stanley Financial Advisors and other authorized financial representatives at the
time of sale totaled $74,429 in the case of Class C at December 31, 2001 (end of
the calendar year), which was equal to 0.17% of the net assets of Class C on
such date, and that there were no such expenses that may be reimbursed in the
subsequent year in the case of Class A on such date. 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.

    No interested person of the Fund nor any Independent Director has any direct
financial interest in the operation of the Plan except to the extent that the
Distributor, the Investment Manager, Morgan Stanley DW, Morgan Stanley Services
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.

    On an annual basis, the Directors, including a majority of the Independent
Directors, consider whether the Plan should be continued. Prior to approving the
last continuation of the Plan, the Directors 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 Directors 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, including that: (a) the Plan is essential in order to
give Fund investors a choice of alternatives for payment of distribution and
service charges and to enable the Fund to continue to grow and avoid a pattern
of net redemptions which, in turn, are essential for effective investment
management; and (b) without the compensation to individual brokers and the
reimbursement of distribution and account maintenance expenses of Morgan Stanley
DW's branch offices made possible by the 12b-1 fees, Morgan Stanley DW could not
establish and maintain an effective system for distribution, servicing of Fund
shareholders and maintenance of shareholder accounts; 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 Directors, including each of the
Independent Directors, 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 Directors' quarterly review of
the Plan, they will consider its continued appropriateness and the level of
compensation provided therein.

    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval 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 Directors or by a vote of a majority of the
outstanding voting securities of the Fund (as defined in the Investment Company
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 Directors shall be committed to the discretion of the Independent
Directors.

may, at times, be substantial.

    Deloitte & Touche LLP, Two World Financial Center, New York, NY 10281,
serves as the independent auditors of the Fund. The independent auditors are
responsible for auditing the annual financial statements of the Fund.

(3) AFFILIATED PERSONS

Distributor. As Transfer Agent and Dividend Disbursing Agent, the Transfer
Agent's responsibilities include maintaining shareholder accounts, disbursing
cash dividends and reinvesting dividends, processing account registration
changes, handling purchase and redemption transactions, mailing prospectuses and

G. CODES OF ETHICS

    The Fund, the Investment Manager and the Distributor have each adopted a
Code of Ethics pursuant to Rule 17j-1 under the Investment Company Act. The
Codes of Ethics are designed to detect and prevent improper personal trading.
The Codes of Ethics permit personnel subject to the Codes to invest in
securities, including securities that may be purchased, sold or held by the
Fund, subject to a number of restrictions and controls including prohibitions
against purchases of securities in an Initial Public Offering and a preclearance
requirement with respect to personal securities transactions.

VI. BROKERAGE ALLOCATION AND OTHER PRACTICES
- --------------------------------------------------------------------------------

A. BROKERAGE TRANSACTIONS

    Subject to the general supervision of the Directors, the Investment Manager
is responsible for decisions to buy and sell securities for the Fund, the
selection of brokers and dealers to effect the transactions, and the negotiation
of brokerage commissions, if any. Purchases and sales of securities on a stock
exchange are effected through brokers who charge a commission for their
services. In the over-the-counter market, securities are generally traded on a
"net" basis with dealers acting as principal for their own accounts without a
stated commission, although the price of the security usually includes a profit
to the dealer. The Fund 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 did not pay any brokerage commissions during the fiscal years ended
August 31, 2000, 2001 and 2002.

B. COMMISSIONS

    Pursuant to an order of the SEC, the Fund may effect principal transactions
in certain money market instruments with Morgan Stanley DW. The Fund will limit
its transactions with Morgan Stanley DW to U.S. government and government agency
securities, bank money instruments (i.e., certificates of deposit

                                       26


and bankers' acceptances) and commercial paper. The transactions will be
effected with Morgan Stanley DW only when the price available from Morgan
Stanley DW is better than that available from other dealers.

    During the fiscal years ended August 31, 2000, 2001 and 2002, the Fund did
not effect any principal transactions with Morgan Stanley DW.

    Brokerage transactions in securities listed on exchanges or admitted to
unlisted trading privileges may be effected through Morgan Stanley DW, Morgan
Stanley & Co. and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions on an exchange
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, including the Independent
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 any amount of the brokerage
commissions it may pay to an affiliated broker or dealer.

    The Fund did not pay any brokerage commissions to any affiliated brokers or
dealers during the fiscal years ended August 31, 2000, 2001 and 2002.

C. BROKERAGE SELECTION

    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. These
determinations are necessarily subjective and imprecise, as in most cases an
exact dollar value for those services is not ascertainable.

    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 the 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. The 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
utilized by the Investment Manager and any of its asset management affiliates in
the management of accounts of some of their other clients and may not in all
cases benefit the Fund directly.

    The Investment Manager and certain of its affiliates currently serves as
investment manager to a number of clients, including other investment companies,
and may in the future act as investment manager or advisor to others. It is the
practice of the Investment Manager and its affiliates to cause purchase and sale
transactions to be allocated among clients whose assets they manage (including
the

                                       27


Fund) in such manner they deem 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.
The Investment Manager and its affiliates may operate one or more order
placement facilities and each facility will implement order allocation in
accordance with the procedures described above. From time to time, each facility
may transact in a security at the same time as other facilities are trading in
that security.

D. DIRECTED BROKERAGE

    During the fiscal year ended August 31, 2002, the Fund did not pay any
brokerage commissions to brokers because of research services provided.

E. REGULAR BROKER-DEALERS

    During the fiscal year ended August 31, 2002, the Fund did not purchase
securities issued by brokers or dealers that were among the ten brokers or the
ten dealers that executed transactions for or with the Fund in the largest
dollar amounts during the year. At August 31, 2002, the Fund did not own any
securities issued by any of such issuers.

VII. CAPITAL STOCK AND OTHER SECURITIES
- --------------------------------------------------------------------------------

    The Fund is authorized to issue 2 billion shares of common stock of $0.01
par value for each Class. Shares of the Fund, when issued, are fully paid,
non-assessable, fully transferrable and redeemable at the option of the holder.
Except for agreements entered into by the Fund in its ordinary course of
business within the limitations of the Fund's fundamental investment policies
(which may be modified only by shareholder vote), the Fund will not issue any
securities other than common stock.

    All shares of common stock 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.

    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
Directors may call special meetings of shareholders for action by shareholder
vote as may be required by the Investment Company Act or the Fund's By-Laws.
Under certain circumstances, the Directors may be removed by action of the
Directors. In addition, under certain circumstances, the shareholders may call a
meeting to remove Directors and the Fund is required to provide assistance in
communicating with shareholders about such a meeting. 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 Directors being selected, while the
holders of the remaining shares would be unable to elect any Directors.

VIII. PURCHASE, REDEMPTION AND PRICING OF SHARES
- --------------------------------------------------------------------------------

A. PURCHASE/REDEMPTION OF SHARES

    Information concerning how Fund shares are offered to the public (and how
they are redeemed and exchanged) is provided in the Fund's Prospectus.

    TRANSFER AGENT AS AGENT.  With respect to the redemption or repurchase of
Fund shares, the application of proceeds to the purchase of new shares in the
Fund or any other Morgan Stanley Funds and the general administration of the
exchange privilege, the Transfer Agent acts as agent for the

                                       28


Distributor and for the shareholder's authorized broker-dealer, if any, in the
performance of such functions. With respect to exchanges, redemptions or
repurchases, the Transfer Agent is liable for its own negligence and not for the
default or negligence of its correspondents or for losses in transit. The Fund
is not liable for any default or negligence of the Transfer Agent, the
Distributor or any authorized broker-dealer.

    The Distributor and any authorized broker-dealer have 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 Morgan
Stanley Fund and the general administration of the exchange privilege. No
commission or discounts will be paid to the Distributor or any authorized
broker-dealer for any transaction pursuant to the exchange privilege.

    TRANSFERS OF SHARES.  In the event a shareholder requests a transfer of Fund
shares to a new registration, the 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 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 CDSC as if they
had not been so transferred.

    OUTSIDE BROKERAGE ACCOUNTS.  If a shareholder wishes to maintain his or her
fund account through a brokerage company other than Morgan Stanley DW, he or she
may do so only if the Distributor has entered into a selected dealer agreement
with that brokerage company. Accounts maintained through a brokerage company
other than Morgan Stanley DW may be subject to certain restrictions on
subsequent purchases and exchanges. Please contact your brokerage company or the
Transfer Agent for more information.

B. OFFERING PRICE

    The Fund's Class B, Class C and Class D shares are offered at net asset
value per share and the Class A shares are offered at net asset value per share
plus any applicable FSC which is distributed among the Fund's Distributor,
Morgan Stanley DW and other authorized dealers as described in Section "V.
Investment Management and Other Services -- E. Rule 12b-1 Plan." The price of
Fund shares, called "net asset value," is based on the value of the Fund's
portfolio securities. Net asset value per share of each Class is calculated by
dividing the value of the portion of the Fund's securities and other assets
attributable to that Class, less the liabilities attributable to that Class, by
the number of shares of that Class outstanding. The assets of each Class of
shares are invested in a single portfolio. The net asset value of each Class,
however, will differ because the Classes have different ongoing fees.

    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, Nasdaq, or
other exchange is valued at its latest sale price, 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 Directors, 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
Directors. For valuation purposes, quotations of foreign portfolio securities,
other assets and liabilities and forward contracts stated in foreign currency
are translated into U.S. dollar equivalents at the prevailing market rates prior
to the close of the New York Stock Exchange.

    Short-term debt securities with remaining maturities of sixty days or less
at the time of purchase are valued at amortized cost, unless the Directors
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
Directors.

                                       29


    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
closing bid and asked prices. Unlisted options on debt 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 fair value, in which
case they will be value at their fair market value as determined by the
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 Directors.

    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.

    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 well 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 price published by 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 in good faith under procedures established by and under the
supervision of the Directors.

    Generally, trading in foreign securities, as well as corporate bonds, U.S.
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 may 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 that may affect the value
of such securities occur during such period, then these securities may be valued
at their fair value as determined in good faith under procedures established by
and under the supervision of the Directors.

IX. TAXATION OF THE FUND AND SHAREHOLDERS
- --------------------------------------------------------------------------------

    The Fund generally will make two basic types of distributions: ordinary
dividends and long-term capital gain distributions. These two types of
distributions are reported differently on a shareholder's income tax return and
they are also subject to different rates of tax. The tax treatment of the
investment activities of the Fund will affect the amount, timing and character
of the distributions made by the Fund. Tax issues relating to the Fund are not
generally a consideration for shareholders such as tax-exempt entities and
tax-advantaged retirement vehicles such as an IRA or 401(k) plan. Shareholders
are urged to consult their own tax professionals regarding specific questions as
to federal, state or local taxes.

    INVESTMENT COMPANY TAXATION.  The Fund intends to remain qualified as a
regulated investment company under Subchapter M of the Internal Revenue Code of
1986, as amended. As such, the Fund will not be subject to federal income tax on
its net investment income and capital gains, if any, to the extent that it
distributes such income and capital gains to its shareholders.

    The Fund generally intends to distribute sufficient income and gains so that
the Fund will not pay corporate income tax on its earnings. The Fund also
generally intends to distribute to its shareholders in each calendar year a
sufficient amount of ordinary income and capital gains to avoid the imposition
of a 4% excise tax although it may not always do so in a particular year.
However, the Fund may instead determine to retain all or part of any net
long-term capital gains in any year for reinvestment. In such event, the Fund
will pay federal income tax (and possibly excise tax) on such retained gains.


                                       30


    Gains or losses on sales of securities by the Fund will be long-term capital
gains or losses if the securities have a tax holding period of more than one
year at the time of such sale. Gains or losses on the sale of securities with a
tax holding period of one year or less will be short-term capital gains or
losses. Special tax rules may change the normal treatment of gains and losses
recognized by the Fund when the Fund invests in forward foreign currency
exchange contracts, options, futures transactions, and non-U.S. corporations
classified as "passive foreign investment companies." Those special tax rules
can, among other things, affect the treatment of capital gain or loss as
long-term or short-term and may result in ordinary income or loss rather than
capital gain or loss. The application of these special rules would therefore
also affect the character of distributions made by the Fund.

    Under certain tax rules, the Fund may be required to accrue a portion of any
discount at which certain securities are purchased as income each year even
though the Fund receives no payments in cash on the security during the year. To
the extent that the Fund invests in such securities, it would be required to pay
out such income as an income distribution in each year in order to avoid
taxation at the Fund level. Such distributions will be made from the available
cash of the Fund or by liquidation of portfolio securities if necessary. If a
distribution of cash necessitates the liquidation of portfolio securities, the
Investment Manager will select which securities to sell. The Fund may realize a
gain or loss from such sales. In the event the Fund realizes net capital gains
from such transactions, its shareholders may receive a larger capital gain
distribution, if any, than they would in the absence of such transactions.

    TAXATION OF DIVIDENDS AND DISTRIBUTIONS.  Shareholders normally will have to
pay federal income taxes, and any state and/or local income taxes, on the
dividends and other distributions they receive from the Fund. Such dividends and
distributions, to the extent that they are derived from net investment income or
short-term capital gains, are taxable to the shareholder as ordinary income
regardless of whether the shareholder receives such payments in additional
shares or in cash.

    Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash. Under current law, the maximum tax rate on long-
term capital gains realized by non-corporate shareholders generally is 20%. A
special lower tax rate of 18% on long-term capital is available to non-corporate
shareholders to the extent the distributions of long-term capital gains are
derived from securities which the Fund purchased after December 31, 2000, and
held for more than five years.

    Shareholders are generally taxed on any ordinary dividend or capital gain
distributions from the Fund in the year they are actually distributed. However,
if any such dividends or distributions are declared in October, November or
December and paid in January then such amounts will be treated for tax purposes
as received by the shareholders on December 31, to shareholders of record of
such month.

    Subject to certain exceptions, a corporate shareholder may be eligible for a
70% dividends received deduction to the extent that the Fund earns and
distributes qualifying dividends from its investments. Distributions of net
capital gains by the Fund will not be eligible for the dividends received
deduction.

    Shareholders who are not citizens or residents of the United States and
certain foreign entities may be subject to withholding of United States tax on
distributions made by the Fund of investment income and short-term capital
gains.

    After the end of each calendar year, shareholders will be sent information
on their dividends and capital gain distributions for tax purposes, including
the portion taxable as ordinary income, and the portion taxable as long-term
capital gains, and the amount of any dividends eligible for the federal
dividends received deduction for corporations.

    PURCHASES AND REDEMPTIONS AND EXCHANGES OF FUND SHARES.  Any dividend or
capital gains distribution received by a shareholder from any investment company
will have the effect of reducing the net asset value of the shareholder's stock
in that company by the exact amount of the dividend or capital gains
distribution. Furthermore, such dividends and capital gains distributions are
subject to federal

                                       31


income taxes. If the net asset value of the shares should be reduced below a
shareholder's cost as a result of the payment of dividends or the distribution
of realized long-term capital gains, such payment or distribution would be in
part a return of the shareholder's investment 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.

    In general, a sale of shares results in capital gain or loss, and for
individual shareholders, is taxable at a federal rate dependent upon the length
of time the shares were held. A redemption of a shareholder's Fund shares is
normally treated as a sale for tax purposes. Fund shares held for a period of
one year or less at the time of such sale or redemption will, for tax purposes,
generally result in short-term capital gains or losses and those held for more
than one year generally will result in long-term capital gains or losses. Under
current law, the maximum tax rate on long-term capital gains realized by non-
corporate shareholders generally is 20%. A special lower tax rate of 18% on
long-term capital gains is available for non-corporate shareholders who
purchased shares after December 31, 2000, and held such shares for more than
five years. This special lower tax rate of 18% for five-year property does not
apply to non-corporate shareholders holding Fund shares which were purchased on
or prior to December 31, 2000, unless such shareholders make an election to
treat the Fund shares as being sold and reacquired on January 1, 2001. A
shareholder making such election may realize capital gains. Any loss realized by
shareholders upon a sale or redemption of shares within six months of the date
of their purchase will be treated as a long-term capital loss to the extent of
any distributions of net long-term capital gains with respect to such shares
during the six-month period.

    Gain or loss on the sale or redemption of shares in the Fund is measured by
the difference between the amount received and the tax basis of the shares.
Shareholders should keep records of investments made (including shares acquired
through reinvestment of dividends and distributions) so they can compute the tax
basis of their shares. Under certain circumstances a shareholder may compute and
use an average cost basis in determining the gain or loss on the sale or
redemption of shares.

    Exchanges of Fund shares for shares of another fund, including shares of
other Morgan Stanley Funds, are also subject to similar tax treatment. Such an
exchange is treated for tax purposes as a sale of the original shares in the
first fund, followed by the purchase of shares in the second fund.

    If a shareholder realizes a loss on the redemption or exchange of a fund's
shares and reinvests in that fund's shares within 30 days before or after the
redemption or exchange, the transactions may be subject to the "wash sale"
rules, resulting in a postponement of the recognition of such loss for tax
purposes.

X. UNDERWRITERS
- --------------------------------------------------------------------------------

    The Fund's shares are offered to the public on a continuous basis. The
Distributor, as the principal underwriter of the shares, has certain obligations
under the Distribution Agreement concerning the distribution of the shares.
These obligations and the compensation the Distributor receives are described
above in the sections titled "Principal Underwriter" and "Rule 12b-1 Plan."

XI. CALCULATION OF PERFORMANCE DATA
- --------------------------------------------------------------------------------


    Prior to July 28, 1997, the Fund offered only one Class of shares subject to
a maximum sales charge of 5.50% and no 12b-1 fee. 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 (i) the actual maximum sales charge applicable to Class A
(i.e., 4.25%) and (ii) the ongoing 12b-1 fee applicable to Class A Shares.
Furthermore, 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. Also set forth below is the actual performance of Class B and Class C as
of their last fiscal year.

                                       32


    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. Yield is calculated for any
30-day period as follows: the amount of interest 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. The yields for the 30-day
period ended August 31, 2002, calculated pursuant to this formula, were 25.68%
for Class A, 26.32% for Class B, 26.26% for Class C and 27.22% for Class D.

    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 operations, if
shorter than any of the foregoing. The ending redeemable value is reduced by any
contingent deferred sales charge ("CDSC") at the end of the one, five, 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 (which in the
case of Class A shares is reduced by the Class A initial sales charge), taking a
root of the quotient (where the root is equivalent to the number of years in the
period) and subtracting 1 from the result. Based on this calculation, the
average annual total returns of Class A for the one year, five year and ten year
period ended August 31, 2002 were -25.03%, -15.21% and -2.66%, respectively. The
average annual total returns for Class B for the one year and five year periods
ended August 31, 2002 and for the period July 28, 1997 (inception of the Class)
through August 31, 2002 were -25.34%, -15.07% and -14.63%, respectively. The
average annual total returns for Class C for the one year and five year periods
ended August 31, 2002 and for the period July 28, 1997 (inception of the Class)
through August 31, 2002 were -22.78%, -15.00% and -14.64%, respectively. The
average annual total returns for Class D for the one year, five year and ten
year period ended August 31, 2002 were -21.45%, -14.29% and -2.00%,
respectively.

    In addition, 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. These calculations may or may not reflect the
imposition of the maximum front-end sales charge for Class A or the deduction of
the CDSC for each of Class B and Class C which, if reflected, would reduce the
performance quoted. For example, the average annual total return of the Fund may
be calculated in the manner described above, but without deduction for any
applicable sales charge. Based on the foregoing calculation, the Fund's average
annual total returns for Class A for the one year, five year and ten year period
ended August 31, 2002 were -21.70%, -14.48% and -2.23%, respectively. The
average annual total returns for Class B for the one year, five year and life of
the Class periods ended August 31, 2002 were -22.00%, -14.89% and -14.54%,
respectively. The average annual total returns for Class C for the one year,
five year and life of the Class periods ended August 31, 2002 were -22.11%,
- -15.00% and -14.64%, respectively. 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
aggregated 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 this calculation, the total returns
for Class A for the one year, five year and ten year period ended August 31,
2002 were -21.70%, -54.24 % and -20.21%, respectively. The total returns for
Class B for the one year, five year and life of the Class


                                       33


periods ended August 31, 2002 were -22.00%, -55.35% and -55.08%, respectively.
The total returns for Class C for the one year, five year and life of the Class
periods ended August 31, 2002 were -22.11%, -55.62% and -55.35%, respectively.
The total returns for Class D for the one year, five year and ten year period
ended August 31, 2002 were -21.45%, -53.74% and -18.32%, respectively.

    The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 and $100,000 in each Class of shares of the Fund by adding 1 to
the Fund's aggregate total return to date (expressed as a decimal and without
taking into account the effect of any applicable CDSC) and multiplying by
$9,575, $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, Class C and Class D, as the
case may be. Investments of $10,000, $50,000 and $100,000 in each Class at
inception of the Class would have grown (or declined) to the following amounts
at August 31, 2002:



                                                       INVESTMENT AT INCEPTION OF:
                                         INCEPTION   --------------------------------
CLASS                                      DATE:     $10,000     $50,000    $100,000
- -----                                    ---------   --------   ---------   ---------
                                                                
Class A...............................   09/26/79    $23,135    $116,583    $234,978
Class B...............................   07/28/97      4,492      22,462      44,924
Class C...............................   07/28/97      4,465      22,325      44,649
Class D...............................   09/26/79     25,540     127,699     255,398


    For purposes of restating the performance of Class A, the inception date set
forth in the above table is the inception date of the Fund. However, Class A did
not actually commence operation until July 28, 1997.

    The after-tax returns of the Fund may also be advertised or otherwise
reported. This is generally calculated in a manner similar to the computation of
average annual total returns discussed above, except that the calculation also
reflects the effect of taxes on returns. Based on these calculations, the
average annual total returns (after taxes on distributions) for Class A for the
one year, five year and the ten year periods ended August 31, 2002 were -29.49%,
- -19.74% and -7.48%, respectively, and the average annual total returns (after
taxes on distributions and redemptions) for Class A for the one year, five year
and the ten year periods ended August 31, 2002 were -15.07%, -12.01% and -3.03%,
respectively. The average annual total returns (after taxes on distributions)
for Class D for the one year, five year and the ten year periods ended
August 31, 2002 were -26.21%, -18.93% and -6.94%, respectively and the average
annual total returns (after taxes on distributions and redemptions) for Class D
for the one year, five year and the ten year periods ended August 31, 2002 were
- -12.86%, -11.43% and -2.59%, respectively.

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

Morgan Stanley High Yield Securities Inc.
NOTES TO FINANCIAL STATEMENTS o AUGUST 31, 2002

1. Organization and Accounting Policies
Morgan Stanley High Yield Securities Inc. (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 was
incorporated in Maryland on June 14, 1979 and commenced operations on
September 26, 1979. On July 28, 1997, the Fund converted to a multiple class
share structure.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within one year, six
years and one year, respectively. Class D shares are not subject to a sales
charge. Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) an equity portfolio security listed or traded
on the New York or American Stock Exchange, Nasdaq, or other exchange is valued
at its latest sale price, 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; (3) when market quotations are not readily available, including
circumstances under which it is determined by Morgan Stanley Investment Advisors
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

                                       50


Morgan Stanley High Yield Securities Inc.
NOTES TO FINANCIAL STATEMENTS o AUGUST 31, 2002 continued

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 and premiums are amortized over the respective life of
the securities. Interest income is accrued daily except where collection is not
expected.

C. Joint Repurchase Agreement Account -- Pursuant to an Exemptive Order issued
by the Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Manager, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, or U.S. Treasury or federal agency obligations.

D. Multiple Class Allocations -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.

E. 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 substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

F. Dividends and Distributions to Shareholders -- The Fund records dividends and
distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes

                                       51



Morgan Stanley High Yield Securities Inc.
NOTES TO FINANCIAL STATEMENTS o AUGUST 31, 2002 continued

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.

3. Plan of Distribution
Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Fund has adopted a
Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The Plan
provides that the Fund pay the Distributor a fee which is accrued daily and paid
monthly at the following annual rates: (i) Class A -- up to 0.25% of the average
daily net assets of Class A; (ii) Class B -- 0.75% of the average daily net
assets of Class B; and (iii) Class C -- up to 0.85% of the average daily net
assets of Class C.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Directors will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that such excess amounts totaled
$60,068,745 at August 31, 2002.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 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

Morgan Stanley High Yield Securities Inc.
NOTES TO FINANCIAL STATEMENTS o AUGUST 31, 2002 continued

gross sales credit to Morgan Stanley Financial Advisors or other selected
broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the year ended August 31, 2002, the distribution fee was accrued for
Class A shares and Class C shares at the annual rate of 0.18% and 0.85%,
respectively.

The Distributor has informed the Fund that for the year ended August 31, 2002,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class A Shares, Class B shares and Class C shares of $26,842, $1,519,542
and $29,347, respectively and received $135,390 in front-end sales charges from

7. Change in Accounting Policy
Effective September 1, 2001, the Fund has adopted the provisions of the AICPA
Audit and Accounting Guide for Investment Companies, as revised, related to
premiums and discounts on debt securities. The cumulative effect of this
accounting change had no impact on the net assets of the Fund, but resulted in a
$5,326,859 increase in the cost of securities and a corresponding increase in
undistributed net investment income based on securities held as of August 31,
2001.

The effect of this change for the year ended August 31, 2002 was to increase net
investment income by $4,981,336; increase unrealized depreciation by $3,780,819;
and increase net realized losses by $1,200,517. The statement of changes in net
assets and the financial highlights for prior periods have not been restated to
reflect this change.

8. Merger
On July 25, 2002, the Trustees of Morgan Stanley High Income Advantage Trust
("HIAT"), Morgan Stanley High Income Advantage Trust II ("HIAT II") and Morgan
Stanley High Income Advantage Trust III ("HIAT III") approved plans of
reorganization whereby HIAT, HIAT II and HIAT III would be merged into the Fund.
The plans of reorganization are subject to the consent of HIAT's, HIAT II's and
HIAT III's shareholders at separate meetings to be held on December 10, 2002. If
approved, the assets of HIAT, HIAT II and HIAT III would be combined with the
assets of the Fund and shareholders of HIAT, HIAT II and HIAT III would become
Class D shareholders of the Fund, receiving Class D shares of the Fund equal to
the value of their holdings in HIAT, HIAT II and HIAT III, respectively.

INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Directors of
Morgan Stanley High Yield Securities Inc.:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley High Yield Securities Inc. (the "Fund"), including the portfolio of
investments, as of August 31, 2002, and the related statements of operations for
the year then ended and changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of August 31, 2002, by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Morgan
Stanley High Yield Securities Inc. as of August 31, 2002, 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 five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.
