the number of shares held in "street name" accounts of

PROXIES

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

     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"), Alamo Direct Mail Services Inc. ("Alamo") or

                                       2



D.F. King & Co. Inc. ("D.F. King") may call Shareholders to ask if they would
be willing to have their votes recorded by telephone. The telephone voting
procedure is designed to authenticate Shareholders' identities, to allow
Shareholders to authorize the voting of their shares in accordance with their
instructions and to confirm that their instructions have been recorded
properly. No recommendation will be made as to how a Shareholder should vote on
the Reorganization Agreement other than to refer to the recommendation of the
Board. HIAT 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 $
and will be borne by HIAT. HIAT 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, 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 may retain D.F. King as proxy solicitor, at a cost to HIAT of
approximately $    plus reimbursement of reasonable expenses. In addition, HIAT
will employ Alamo to make telephone calls to Shareholders to remind them to
vote. 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 D.F. King, additional expenses would include [$7.00] per
telephone vote transacted, [$3.00] per outbound telephone contact and costs
relating to obtaining Shareholders' telephone numbers, and, with respect to
Alamo, expenses would be approximately $1.00 per outbound telephone contact,
which would be borne by HIAT.


VOTE REQUIRED

     Approval of the Reorganization Agreement by the Shareholders requires the
vote of a majority of the outstanding shares of HIAT which means an affirmative
vote of the lesser of (1) a majority of the outstanding shares of HIAT, or (2)
67% or more of the shares of HIAT represented at the Meeting if more than 50%
of the outstanding shares of HIAT are present or represented by proxy. If the
Reorganization Agreement is not approved by Shareholders, HIAT 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, 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 received by High Yield. On or after the closing date of the
Reorganization, currently anticipated to be December   , 2002, (the "Closing
Date"), HIAT will distribute the High Yield Shares received by HIAT to
Shareholders as of the Valuation Date (as defined below under "The
Reorganization Agreement") in complete liquidation of HIAT and HIAT 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 transferred to
High Yield. Accordingly, as a result of the Reorganization, each Shareholder of
HIAT will become a holder of Class D shares of High Yield. Shareholders holding
their shares of HIAT 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 ("INDEPENDENT TRUSTEES"), AS THAT TERM IS DEFINED IN THE 1940
ACT, HAS CONCLUDED THAT THE REORGANIZATION IS IN THE BEST INTERESTS OF HIAT AND
ITS SHAREHOLDERS AND RECOMMENDS APPROVAL OF THE REORGANIZATION AGREEMENT.


FEE TABLE


     HIAT 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. The following table briefly describes the fees and expenses that a
shareholder of HIAT and a Class D shareholder of High Yield may pay if they buy
and hold shares of each respective fund. These expenses are deducted from each
respective fund's assets and are based on expenses paid by HIAT for its fiscal
year ended September 30, 2001 and on expenses paid by Class D shares of High
Yield for its fiscal year ended August 31, 2002. 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.

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 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

     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 complete
description of these costs and expenses, see "Comparison of HIAT 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 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 or the shareholders of HIAT 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 shareholders. In particular, the Reorganization would
afford HIAT shareholders the opportunity for a continued interest in a fund
which has investment objectives similar to that of HIAT, and which is
substantially larger and has a significantly lower expense ratio than HIAT. 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 AND HIGH YIELD

     INVESTMENT OBJECTIVES AND POLICIES. HIAT and High Yield have similar
investment objectives. As their primary investment objective, HIAT and High
Yield seek to earn a high level of current income. As their secondary
investment objective, HIAT and High Yield seek capital appreciation but only
when consistent with their primary investment objective. The respective
investment objectives of HIAT 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 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 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's investment manager, MS Advisors, provides administrative
services and manages HIAT'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 in a
manner consistent with its objective and policies. As compensation for advisory
services provided to HIAT, HIAT pays MS Advisors monthly compensation
calculated weekly by applying the following annual rates to HIAT'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 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 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


                                       6


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 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 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, 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 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.

     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.


                                       7



     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 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 are only
purchased and sold on the NYSE.

     DIVIDENDS. Both High Yield and HIAT declare and pay dividends from net
investment income monthly. Both High Yield and HIAT 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 are automatically included in HIAT'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 at the
then current market price of such shares. For more information on HIAT'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 on the NYSE as well as HIAT'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 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
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


                                       8



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 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 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 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 Shareholders approve the


                                       9



Reorganization Agreement. In reaching this decision, the Board made an
extensive inquiry into a number of factors, particularly the comparative
expense ratios of HIAT and the Class D shares of High Yield, and the effect on
Shareholders of "open-ending" HIAT 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 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 and High Yield in connection with the
Reorganization.

     In recommending the Reorganization to Shareholders, the Board of HIAT
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; ____________ for its fiscal year end August 31,
2002) is substantially lower than the expense ratio for HIAT (1.32% for its
fiscal year end September 30, 2001). 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 (_____________ for its
fiscal year end August 31, 2002) than HIAT's investment management fee rate
(0.75%) paid for the twelve months ended August 31, 2001. 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 (______________ for
its fiscal year end August 31, 2002) was lower than the rate of other expenses
paid by HIAT (0.57% of average daily net assets) for the its last fiscal year.
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.

     2. HIAT, 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 is trading at a
discount on the date of the Reorganization, the Reorganization at net asset
value would benefit the Shareholders of HIAT by immediately eliminating any
such discount.

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

     4. 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, being a closed-end fund, does not offer any exchange
privileges.

     5. HIAT 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.

     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 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 is
trading at a premium to its net asset value, HIAT 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. See "Additional Matters
Regarding HIAT -- History of Public Trading of HIAT'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.


                                       10


     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'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. 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 will transfer all of
its assets, including portfolio securities, cash (other than cash amounts
retained by HIAT 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, including all expenses, costs, charges and
reserves, as reflected on an unaudited statement of assets and liabilities of
HIAT prepared by the Treasurer of HIAT, 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 would be
de-registered as an investment company under the 1940 Act; (iv) HIAT would be
dissolved as a Massachusetts business trust; and (v) the outstanding shares of
HIAT would be canceled.

     The number of High Yield Shares to be delivered to HIAT will be determined
by dividing the aggregate net asset value of the shares of HIAT 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 and High Yield may agree (the "Valuation Date"). As an illustration,
assume that on the Valuation Date, the shares of HIAT had an aggregate net asset
value (not including any Cash Reserve of HIAT) 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. 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 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
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,


                                       11



Harborside Financial Center, Jersey City, New Jersey 07311. Shareholders of
HIAT 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 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 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, which
expenses are expected to approximate $ . HIAT 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, 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 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 that received High Yield Shares.
HIAT 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.

     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 (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 recognizes net 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's shares, which is
currently expected to occur on the next business day after the Meeting
(assuming Shareholders of HIAT approve the Reorganization Agreement at the
Meeting), Shareholders will continue to be able to sell their shares of HIAT 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 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 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's investment company taxable income for all periods
since the inception of HIAT through and including the Valuation Date (computed
without regard to any dividends paid deduction), and all of HIAT's net capital
gain, if any, realized in such periods (after reduction for any capital loss
carryforward).


                                       12



     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 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 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 fifty
percent of the assets of HIAT acquired in the Reorganization except for
dispositions made in the ordinary course of business):

     1. The transfer of HIAT's assets in exchange for the High Yield Shares and
the assumption by High Yield of certain stated liabilities of HIAT followed by
the distribution by HIAT of the High Yield Shares to Shareholders in exchange
for their HIAT 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 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 solely in exchange for the High Yield Shares and the
assumption by High Yield of the stated liabilities of HIAT;

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

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

     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 surrendered
in exchange therefor were held (provided such shares in HIAT were held as
capital assets on the date of the Reorganization);

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

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

     The advice of Counsel is not binding on the Internal Revenue Service or
the courts and neither HIAT 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 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. The
effect of any such limitations will depend on the existence and


                                       13



amount of HIAT'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 $1.3 million of HIAT'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 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 (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 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.

     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, whose shares are listed on the NYSE, does
hold annual meetings as required by the rules of the NYSE.

     HIAT 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. However, the Declaration of Trust contains an express
disclaimer of shareholder liability for acts or obligations of HIAT, requires
that notice of such HIAT obligations include such disclaimer, and provides for
indemnification out of the HIAT's property for any shareholder held personally
liable for the obligations of HIAT. Thus, the risk of a shareholder incurring
financial loss on account of


                                       14



shareholder liability is limited to circumstances in which HIAT 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 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, 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 (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 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 with or into any other corporation;


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



     (iii) sale, lease or exchange of all or any substantial part of the
           assets of HIAT, 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, in exchange for securities of HIAT,
           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. 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 (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.

     The following table sets forth the capitalization of High Yield and HIAT
as of July 31, 2002 and on a pro forma combined basis as if the Reorganization

APPRAISAL RIGHTS

     Shareholders will have no appraisal rights in connection with the
Reorganization.


        COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS


INVESTMENT OBJECTIVES AND POLICIES

     HIAT and High Yield have similar investment objectives. Both HIAT and High
Yield, as a primary investment objective, seek to earn a high level current
income. As a secondary investment objective, HIAT 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
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.


                                       16



     HIAT 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 and High Yield may
include both convertible and nonconvertible debt securities and preferred
stock. Under normal conditions, 20% of HIAT's total assets may be invested in
higher-rated fixed-income securities and unrated fixed-income securities of
comparable quality and HIAT also may invest up to 10% of its assets in
municipal obligations. HIAT may also purchase common stocks, foreign
securities, money market instruments and may acquire warrants and unit
offerings.

     Both High Yield and HIAT 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 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 may be changed without shareholder approval.

     Both High Yield and HIAT 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 may not invest in repurchase agreements
that do not mature within seven days, if any such investments amount to more
than 10% of HIAT'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), (vi) lend their
portfolio securities (up to 25% in the case of High Yield and up to 10% in the
case of HIAT), 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 and High Yield as fundamental
policies are substantially similar. HIAT'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.

     HIAT 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


                                       17



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's portfolio; however, HIAT 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'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 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.


                                       18



     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 AND HIGH YIELD


GENERAL

     HIAT was organized as a "Massachusetts business trust" under the laws of
the Commonwealth of Massachusetts on June 17, 1987 and commenced operations as
a closed-end registered investment company on October 29, 1987. 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 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.

                      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, a Massachusetts business trust ("HIAT").

     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 in exchange
for the assumption by High Yield of all stated liabilities of HIAT 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 in liquidation of
HIAT 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

     1.1 Subject to the terms and conditions herein set forth and on the basis
of the representations and warranties contained herein, HIAT agrees to assign,
deliver and otherwise transfer the HIAT Assets (as defined in paragraph 1.2) to
High Yield and High Yield agrees in exchange therefor to assume all of HIAT
stated liabilities on the Closing Date as set forth in paragraph 1.3(a) and to
deliver to HIAT 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 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, and any deferred or prepaid expenses shown as an asset on HIAT's
books on the Valuation Date.

     (b) On or prior to the Valuation Date, HIAT will provide High Yield with a
list of all of HIAT 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 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 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 holds
any investments that High Yield is not permitted to hold, HIAT will dispose of
such securities on or prior to the Valuation Date. In addition, if it is
determined that the portfolios of HIAT and High Yield, when aggregated, would
contain investments exceeding certain percentage limitations imposed upon High
Yield with respect to such investments, HIAT 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 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 prepared by the Treasurer of HIAT, 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 may establish a cash reserve, which shall
not exceed 5% of HIAT's net assets as of the close of business on the Valuation
Date ("Cash Reserve") to be retained by HIAT 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 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 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 will
distribute High Yield Shares received by HIAT pursuant to paragraph 1.1 pro
rata to its shareholders of record determined as of the close of business on
the Valuation Date ("HIAT Shareholders"). Each HIAT Shareholder will receive
Class D shares of High Yield. Such distribution will be accomplished by an
instruction, signed by the Secretary of HIAT, to transfer High Yield Shares
then credited to HIAT's account on the books of High Yield to open accounts on
the books of High Yield in the names of the HIAT Shareholders and representing
the respective pro rata number of High Yield Shares due such HIAT Shareholders.
All issued and outstanding shares of HIAT simultaneously will be canceled on
HIAT's books; however, share certificates representing interests in HIAT 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 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'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 is and shall remain the
responsibility of HIAT up to and including the date on which HIAT is dissolved
pursuant to paragraph 1.9.

     1.9 Within one year after the Closing Date, HIAT shall pay or make
provision for the payment of all its liabilities and taxes, and distribute to
the shareholders of HIAT 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, 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 for federal income tax purposes, or (ii) be
subject to a waiver under Section 368(a)(2)(G)(ii) of the complete distribution
requirement of Section 368(a)(2)(G)(i) of the Code. HIAT 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).


                                      A-2


     1.10 Copies of all books and records maintained on behalf of HIAT 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 is subject
under the 1940 Act.


2. VALUATION

     2.1 The value of the HIAT 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 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'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 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 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      a.m.
Eastern time on    , 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 and High Yield. All acts taking place at the
Closing shall be deemed to take place simultaneously as of      a.m. Eastern

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
to the Custodian for the account of High Yield on or before the Closing Date in
conformity with applicable custody provisions under the 1940 Act and duly
endorsed in proper form for transfer in such condition as to constitute good
delivery thereof in accordance with the custom of brokers. The portfolio
securities shall be accompanied by all necessary Federal and state stock
transfer stamps or a check for the appropriate purchase price of such stamps.
Portfolio securities and instruments deposited with a securities depository (as
defined in Rule 17f-4 under the 1940 Act) shall be delivered on or before the
Closing Date by book-entry in accordance with customary practices of such
depository and the Custodian. The cash delivered shall be in the form of a
Federal Funds wire, payable to the order of "The Bank of New York, Custodian
for Morgan Stanley High Yield Securities Inc."


                                      A-3


     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, accurate
appraisal of the value of the net assets of High Yield or the HIAT 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 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 Shareholders and the number and
percentage ownership of outstanding HIAT shares owned by each such HIAT
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
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 or provide evidence satisfactory to HIAT
that such High Yield Shares have been credited to HIAT'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.

   required for the consummation by High Yield 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

     6.4 As of the Closing Date, there shall have been no material change in

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 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 contained in this Agreement
shall be true and correct in all material respects as of the date hereof and,
except as they may be affected by the transactions contemplated by this
Agreement, as of the Closing Date with the same force and effect as if made on
and as of the Closing Date;

     7.2 HIAT 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 the representations
and warranties of HIAT made in this Agreement are true and correct at and as of
the Closing Date, except as they may be affected by the transactions
contemplated by this Agreement, and as to such other matters as High Yield
shall reasonably request;

     7.3 HIAT shall have delivered to High Yield a statement of the HIAT Assets
and its liabilities, together with a list of HIAT's portfolio securities and
other assets showing the respective adjusted bases and holding periods thereof
for income tax purposes, as of the Closing Date, certified by the Treasurer of
HIAT;

     7.4 HIAT shall have delivered to High Yield within three business days
after the Closing (a) a letter from PricewaterhouseCoopers LLP with respect to
the taxable year ended September 30, 1999, and a letter from Deloitte & Touche
for the taxable years ended September 30, 2000 and 2001, 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 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 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 September 30, 2001 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, state and
local tax liabilities for the period from September 30, 2001 to and including
the Closing Date. Each respective letter shall contain a statement that based on
such limited reviews, nothing came to their respective attention that caused
them to believe that HIAT would not qualify as a regulated investment company
for Federal income tax purposes for any such year or period;

     7.5 High Yield shall have received at the Closing a favorable opinion from
Mayer, Brown, Rowe & Maw, counsel to HIAT, dated as of the Closing Date to the
effect that:

     (a) HIAT is a validly existing Massachusetts business trust and has the
   power to own all of its properties and assets and to carry on its business
   as presently conducted (Massachusetts counsel may be relied upon in
   delivering such opinion); (b) HIAT is a duly registered, closed-end,
   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 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 of HIAT
   enforceable against HIAT in accordance with its terms, 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


                                      A-10


   execution and delivery of this Agreement did not, and the consummation of
   the transactions contemplated hereby will not, violate HIAT'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 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 On the Closing Date, the HIAT Assets shall include no assets that High
Yield, by reason of limitations of the fund's Articles of Incorporation or
otherwise, may not properly acquire.

Act, no stop orders suspending the effectiveness thereof shall have been issued
and, to the best knowledge of the parties hereto, no investigation or

threatened or contemplated under the 1933 Act;

   will include the period during which those assets were held by HIAT.

     Notwithstanding anything herein to the contrary, neither High Yield nor
HIAT may waive the conditions set forth in this paragraph 8.6.

Morgan Stanley High Yield Securities Inc.
LETTER TO THE SHAREHOLDERS o FEBRUARY 28, 2002

Dear Shareholder:
The six-month period ended February 28, 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 outlooks
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.

Within the high-yield sector, airlines, lodging and insurance, as well as
telecommunications and cable, experienced the largest sell-off in September.
Even sectors that held up relatively well, such as food, drugs, utilities and
energy, experienced price declines. Many telecommunications-related companies
also announced poor earnings and lower revenues, which pushed the whole sector
lower throughout much of the past six months. Relative performance was
particularly exaggerated for lower tier credits. The market recovered somewhat
in October and November, but then moved mostly sideways from December through
February. The market's recovery was of limited benefit to companies pushed into
default.

Credit spreads relative to U.S. Treasury securities in the high-yield market
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
During the six-month period ended February 28, 2002, Morgan Stanley High Yield
Securities' Class A and D shares produced returns of -13.32 percent and -13.56
percent, respectively. The Fund underperformed the Lehman Brothers U.S.
Corporate High Yield Index, which returned -2.03 percent.* For the same period,
the Fund's Class B and C shares had total returns of -13.85 percent and -13.92
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.

Over the past year, the Fund instituted several important changes to its
dividend policy. First, in May the Fund lowered its income dividend from $0.04
per share to $0.03 per share. In January 2002, the monthly income dividend was
lowered to $0.022 per share. The Fund moved from paying a fixed dividend rate to
one that fluctuates with the amount of income earned by the Fund. We believe
that adopting a fluctuating dividend policy will provide the Fund with greater
flexibility. Should the Fund experience additional defaults, the dividend amount
will be lower. Conversely, should the economy improve, defaults stabilize and
income levels increase, the Fund's dividend rate could rise.

- ----------------
* 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.



Morgan Stanley High Yield Securities Inc.
LETTER TO THE SHAREHOLDERS o FEBRUARY 28, 2002 CONTINUED

The Fund's position in the lower-rated portion of the market adversely affected
its relative performance. Allocations in fixed-line communications and to a
lesser extent in wireless communications were the major reasons for
disappointing performance. Fixed-line telecommunications was the weakest sector
during the past six months, down more than 30 percent. This sector's high
default rate and rating downgrades led investors to sell it as a sector, which
pushed prices lower. We have reduced the Fund's exposure to this sector over the
past year, but its higher than market weighting adversely affected overall Fund
performance.

Over the past year, the Fund's portfolio management team continued to reposition
it for the current market environment. The team initiated positions in more than
15 new companies, including Collins and Aikman, Stone Energy, Healthnet, Dana
Corp., Autonation and Equistar. The team also increased the overall credit
quality of the portfolio by buying BB-rated securities and trimming the Fund's
exposure to the telecommunications sector. The team continues to maintain
constructive positions in wireline and wireless communications, cable and media.
While many telecommunications issuers have had problems in this very challenging
environment, the team believes that investor sentiment has become excessively
negative. The team's value-oriented analysis suggests that this sector may be
poised for better performance in the months ahead.

Looking Ahead
As a result of the events of September 11, we believe that the economic
environment will be weaker in the early part of 2002 than previously
anticipated. 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 Fund's portfolio is
positioned to participate in any potential recovery.

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

Very truly yours,

/s/ Charles A. Fiumefreddo               /s/ Mitchell M. Merin

  PRIOR TO JULY 28, 1997 THE FUND OFFERED ONLY ONE CLASS OF SHARES. BECAUSE THE

  AN ONGOING 12B-1 FEE WHICH IS REFLECTED IN THE RESTATED PERFORMANCE FOR THAT

Morgan Stanley High Yield Securities Inc.
NOTES TO FINANCIAL STATEMENTS o FEBRUARY 28, 2002 (UNAUDITED)

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

                                       18

Morgan Stanley High Yield Securities Inc.
NOTES TO FINANCIAL STATEMENTS o FEBRUARY 28, 2002 (UNAUDITED) 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 for 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

                                       19

Morgan Stanley High Yield Securities Inc.
NOTES TO FINANCIAL STATEMENTS o FEBRUARY 28, 2002 (UNAUDITED) 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
$60,729,773 at February 28, 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 FEBRUARY 28, 2002 (UNAUDITED) 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 six months ended February 28, 2002, the distribution fee was accrued for
Class A shares and Class C shares at the annual rate of 0.25% and 0.85%,
respectively.

The Distributor has informed the Fund that for the six months ended
February 28, 2002, it received contingent deferred sales charges from certain

NOTES TO FINANCIAL STATEMENTS o FEBRUARY 28, 2002 (UNAUDITED) continued

Capital losses incurred after October 31 ("post-October losses") within the
taxable year are deemed to arise on the first business day of the Fund's next
taxable year. The Fund incurred and will elect to defer net capital losses of
approximately $199,075,000 during fiscal 2001.

At August 31, 2001, the Fund had temporary book/tax differences primarily
attributable to post-October losses, capital loss deferrals on wash sales and
interest on bonds in default.

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
$5,324,128 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 six months ended February 28, 2002 was to
increase net investment income by $952,867; increase unrealized depreciation by
$233,149; and increase net realized losses by $719,718. The statement of changes
in net assets and the financial highlights for prior periods have not been
restated to reflect this change.

Morgan Stanley Dean Witter High Income Advantage Trust
LETTER TO THE SHAREHOLDERS - SEPTEMBER 30, 2001

Dear Shareholder:

During the 12-month period ended September 30, 2001, the high-yield market was
quite volatile. October and November 2000, as well as September 2001, were
particularly difficult. The market's decline was caused by a stream of negative
corporate developments in industries related to the telecommunications sector, a
declining equity market, a large new-issue calendar in the spring and a
continued high default rate. Many high-yield issuers, especially within or
dependent upon the telecommunications sector, announced poor earnings and lower
revenues, which pushed the high-yield market lower throughout most of the past
12 months.

The terrorist attacks of September 11 and subsequent events constituted an
additional shock to an already soft economy and the high-yield market. Liquidity
worsened on both the buy and sell sides as dealers resisted putting their
capital at risk. The industries that experienced the largest sell-off within the
high-yield market in September included airlines, insurance, lodging and
telecommunications-related and cable sectors. As was the case throughout the
fiscal year, lower-rated high-yield bonds tended to underperform higher-quality
issues as investors continued to shy away from that portion of the market.

Performance and Portfolio Strategy

For the 12-month period ended September 30, 2001, Morgan Stanley Dean Witter
High Income Advantage Trust produced a total return of -48.60 percent, based on
a change in net asset value (NAV) and reinvestment of distributions totaling
$0.352 per share. For the same period, the Trust's total return was -56.83
percent, based on a change in its market price on the New York Stock Exchange
(NYSE) and reinvestment of distributions.

The past three years have been one of the most difficult periods for the
high-yield market. As a result of substantial weakness in the market, we have
seen high-yield bond prices decline sharply and yields correspondingly rise over
this period. The Trust's core position in the B-rated sector was adversely
affected. Our allocations in the sectors related to fixed-line communications
and to a lesser extent in wireless communications were the major reasons for the
Trust's disappointing performance. Fixed-line telecom was the worst-performing
industry within the telecommunications sector during the past 12 months. This
industry experienced a high default rate and many ratings downgrades, which led
investors to sell the sector and pushed prices down for most telecom-related
bonds.

In our opinion, while many telecommunications-related issuers have had problems
in this very challenging environment, investor sentiment has become excessively
negative. Our value-oriented analysis suggests that this sector may be poised
for better performance in the months ahead.






Morgan Stanley Dean Witter High Income Advantage Trust
LETTER TO THE SHAREHOLDERS - SEPTEMBER 30, 2001 continued




Our new portfolio management team, which began managing the Fund in January, has
been actively repositioning the portfolio for the current market environment. We
have initiated positions in more than 30 new companies, including Allied Waste,
Chesapeake Energy, Schuler Homes, Salem Communications, Healthnet, Prime Media,
Quebecor, Nextmedia and Beazer Homes. We eliminated positions in many companies
such as Berry Plastics, Fleming, Envirodyne, J.B. Williams, Sabreliner and
Windemere. In addition, we have increased the overall credit quality of the
portfolio by buying BB-rated securities and trimming our exposure to the telecom
sector. However, we continue to maintain constructive positions in wireline
communications, cable, wireless communications and media.

Looking Ahead

As a result of the September 11 attacks, over the near term the economy is
expected to be weaker than previously anticipated. However, we believe that
prices and wide spreads in the high-yield market are currently at levels that
would be consistent with a more prolonged economic downturn and higher default
rates than is likely to occur. In our view, recent stimulative monetary and
fiscal policy initiatives may lead to more-normal economic conditions in 2002.
We believe that the high-yield market would benefit from an improvement in the
economy.

We would again like to remind shareholders that the Trustees have approved a
procedure whereby the Fund 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 lower at the time of purchase.

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



  Very truly yours,

/s/ CHARLES A. FIUMEFREDDO              /s/ MITCHELL M. MERIN

NOTES TO FINANCIAL STATEMENTS - SEPTEMBER 30, 2001





1. Organization and Accounting Policies

Morgan Stanley Dean Witter High Income Advantage Trust (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 was organized as a Massachusetts business trust on
June 17, 1987 and commenced operations on October 29, 1987.

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 security is valued on
the exchange designated as the primary market pursuant to procedures adopted by
the Trustees); (2) all other portfolio securities for which over-the-counter
market quotations are readily available are valued at the latest available bid
price; (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 and bid prices are not reflective of a security's market value,
portfolio securities are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the
Trustees; (4) certain of the 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 Dean Witter High Income Advantage Trust
NOTES TO FINANCIAL STATEMENTS - SEPTEMBER 30, 2001 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 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 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 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 tax purposes are reported as distributions of paid-in-capital.

2. Investment Management Agreement

Pursuant to an Investment Management Agreement with the Investment Manager, the
Trust pays a management fee, accrued 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 year ended September 30, 2001 aggregated
$31,796,999 and $36,670,168, respectively.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager, is
the Trust's transfer agent. At September 30, 2001, the Trust had transfer agent
fees and expenses payable of approximately $13,000.

The Trust has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Trust who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended September 30, 2001
included in Trustees' fees and expenses in the Statement of Operations amounted
to $8,025. At September 30, 2001, the Trust had an accrued pension liability of
$58,357 which is included in accrued expenses in the Statement of Assets and
Liabilities.

6. Federal Income Tax Status

At September 30, 2001, the Trust had a net capital loss carryover of
approximately $73,135,000, to offset future capital gains to the extent provided
by regulations, available through September 30 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 $20,142,000 during fiscal 2001.

As of September 30, 2001, the Trust had temporary book/tax differences primarily
attributable to post-October losses, capital loss deferrals on wash sales and
interest on bonds in default and permanent book/tax differences primarily
attributable to an expired capital loss carryover. To reflect reclassifications
arising from the permanent differences, paid-in-capital was charged $113,431,
accumulated net realized loss was credited $108,937 and dividends in excess of
net investment income was credited $4,494.

7. Change In Accounting Policy

Effective October 1, 2001, the Fund will adopt 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 will have no impact on the net assets of the Fund, but will result in an
adjustment to the cost of securities and a corresponding adjustment to
undistributed net investment income based on securities held as of September 30,
2001.

Morgan Stanley Dean Witter High Income Advantage Trust
REVISED INVESTMENT POLICY/PORTFOLIO MANAGER CHANGE

On February 21, 2001, the Trustees of the Trust approved an investment policy
whereby the Trust would be permitted to invest, to a limited extent, in
asset-backed securities. Asset-backed securities represent an interest in a pool
of assets such as automobile and credit card receivables or home equity loans
which 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. Like
mortgage-backed securities, asset-backed securities 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.

Morgan Stanley High Income Advantage Trust
LETTER TO THE SHAREHOLDERS [] MARCH 31, 2002

Dear Shareholder:

During the six-month period ended March 31, 2002, the high-yield market settled
down after experiencing a spike in volatility in the weeks following the
September 11 terrorist attacks. Immediately following the attacks, market
liquidity became extremely thin and bid prices dropped sharply. This was
particularly true among the relatively weaker credits, several of which slipped
into bankruptcy. By the end of September, however, the market's liquidity had
improved and prices rose for issuers that were expected to benefit from an
anticipated economic recovery.

Despite a renewed softening in expectations for the economy in general and the
high-yield market in particular toward the end of last year, data early in 2002
were consistent with expectations for an upturn in the economy. Against this
backdrop, investors appeared to believe that the high-yield market would improve
in line with the overall economy. Consequently, investor inflows into the
high-yield market tended to be supportive. During March alone there were net
inflows of almost $3 billion into high-yield funds. On the negative side, many
telecommunications-related companies continued to announce poor earnings and
lower revenues, which pushed the sector lower throughout much of the six-month
period. In addition, issuers that were perceived to have used aggressive
accounting techniques tended to perform poorly in the post-Enron environment.

Credit spreads in the high-yield market relative to U.S. Treasury securities
remained at historically wide levels after nearly reaching their all-time peak
during September. Spreads also remained wide 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 most of
the sectors not related to telecommunications performed relatively better as
investors continued to be concerned about the future of many
telecommunications-related companies.


Performance

For the six-month period ended March 31, 2002, Morgan Stanley High Income
Advantage Trust produced a total return of -3.00 percent, based on a change in
net asset value (NAV) and reinvestment of distributions totaling $0.0905 per
share. For the same period, the Trust's total return was -12.21 percent, based
on a change in its market price on the New York Stock Exchange (NYSE) and
reinvestment of distributions.

In January, the Trust instituted an important change to its dividend policy.
First, the income dividend declared in January 2002 was lowered to $0.01125 per
share from $0.017 per share. Second, 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 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.







Morgan Stanley High Income Advantage Trust
LETTER TO THE SHAREHOLDERS [] MARCH 31, 2002 continued

Portfolio Strategy

The Trust's position in the lower-rated portion of the market adversely affected
its relative performance. Allocations in fixed-line communications and to a
lesser extent in wireless communications were the major reasons for
disappointing performance. Fixed-line telecommunications was the weakest sector
during the past six months, down more than 30 percent. This sector's high
default rate and rating downgrades led investors to sell it as a sector, which
pushed prices lower. Although the portfolio management team reduced the Trust's
investments in these industries over the past year, the allocation to this
sector remained high relative to market weights.

Over the past six months, the Trust's portfolio management team continued to
reposition it for the current market environment. The team initiated positions
in more than 15 new companies, including Collins and Aikman, Stone Energy,
Mailwell, Dana Corp., Autonation and Equistar. The team also increased the
overall credit quality of the portfolio and trimmed the Trust's exposure to the
telecommunications sector. The team continues to maintain constructive positions
in wireline and wireless communications, cable and media.


Looking Ahead

As discussed, the high-yield market is at historically wide interest-rate spread
levels relative to U.S. Treasury securities. The Trust's portfolio management
team believes that the current spread of the high-yield market is pricing in a
more extended period of high default rates than is likely to occur. At the
macroeconomic level, the monetary and fiscal policy moves that have been
implemented are expected to bring the economy back to more normal growth levels.
If this scenario proves true, it may provide a basis for the high-yield market
to perform better during the period ahead.

We would again like to remind shareholders 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 lower at the time of purchase.

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



Very truly yours,



/s/ Charles A. Fiumefreddo               /s/  Mitchell M. Merin

Morgan Stanley High Income Advantage Trust
NOTES TO FINANCIAL STATEMENTS o MARCH 31, 2002 (unaudited)

1.  Organization and Accounting Policies
Morgan Stanley High Income Advantage Trust (the "Trust"), formerly Morgan
Stanley Dean Witter High Income Advantage 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 was
organized as a Massachusetts business trust on June 17, 1987 and commenced
operations on October 29, 1987.

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 security is valued on
the exchange designated as the primary market pursuant to procedures adopted by
the Trustees); (2) all other portfolio securities for which over-the-counter
market quotations are readily available are valued at the latest available bid
price; (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 and bid prices are not reflective of
a security's market value, portfolio securities are valued at their fair value
as determined in good faith under procedures established by and under the
general supervision of the Trustees; (4) certain of the portfolio securities may
be valued by an outside pricing service approved by the Trustees. The pricing
service may utilize a matrix system incorporating security quality, maturity and
coupon as the evaluation model parameters, and/or research and evaluations by
its staff, including review of broker-dealer market price quotations, if
available, in determining what it believes is the fair valuation of the
portfolio securities valued by such pricing service; and (5) short-term debt
securities having a maturity date of more than sixty days at time of purchase
are valued on a mark-to-market basis until sixty days prior to maturity and
thereafter at amortized cost based on their value on the 61st day. Short-term
debt securities having a maturity date of sixty days or less at the time of
purchase are valued at amortized cost

B. Accounting for Investments - Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the


                                       18

NOTES TO FINANCIAL STATEMENTS o MARCH 31, 2002 (unaudited) continued

identified cost method. Discounts are accreted 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 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 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 net
realized capital gains. To extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.


2. Investment Management Agreement
Pursuant to an Investment Management Agreement with the Investment Manager, the
Trust pays a management fee, accrued 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 March 31, 2002 aggregated
$7,054,037 and $7,323,700, respectively.

of service. Aggregate pension costs for the six months ended March 31, 2002
included in Trustees' fees and expenses in the Statement of Operations amounted
to $3,744. At March 31, 2002, the Trust had an accrued pension liability of

Morgan Stanley High Income Advantage Trust
NOTES TO FINANCIAL STATEMENTS o MARCH 31, 2002 (unaudited) continued

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 $20,142,000 during fiscal 2001.

At September 30, 2001, the Trust had temporary book/tax differences primarily
attributable to post-October losses, capital loss deferrals on wash sales and
interest on bonds in default.

7. Change in Accounting Policy

Effective October 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 $223,032 increase in the cost of securities and a corresponding increase to
undistributed net investment income based on securities held as of September 30,
2001.

The effect of this change for the six months ended March 31, 2002 was to
increase net investment income by $36,460; increase unrealized depreciation by
$31,023 and increase net realized losses by $5,437. The statement of changes in
net assets and the financial highlights for prior periods have not been restated
to reflect this change.
