THE PERFORMANCE OF THE FUND'S FOUR SHARE CLASSES VARIES BECAUSE EACH HAS
DIFFERENT EXPENSES. THE TOTAL RETURN FIGURES SHOWN ASSUME THE REINVESTMENT OF
ALL DISTRIBUTIONS, BUT DO NOT REFLECT THE DEDUCTION OF ANY APPLICABLE SALES
CHARGES. IF SALES CHARGES WERE INCLUDED, RETURNS WOULD BE LOWER. PAST
PERFORMANCE IS NO GUARANTEE OF FUTURE RESULTS. SEE PERFORMANCE SUMMARY FOR
STANDARDIZED PERFORMANCE INFORMATION.

MARKET CONDITIONS

Market returns during the period were dominated by the high-yield rally that
lasted from mid-October, 2002, through the end of June. The rally was triggered
by a combination of improving fundamentals, declining default rates and record
inflows into the high-yield market, and by the end of June represented the
second-greatest nine-month gain in the market's history. The rallying market
drew record fund inflows, which in turn propelled prices still higher.

The strongest returns during the course of that period were earned by sectors
and securities that were most heavily out of favor during the preceding years.
Wireless communications, utilities, telecommunications and cable all soared
after performing dismally earlier in 2002. These sectors benefited from a
combination of improved financial results (albeit based on greatly reduced
expectations) and low valuations. In a similar vein, performance patterns across
credit tiers differed dramatically as the lowest-rated credits rose far higher
than their higher-quality peers.

While technical factors remained a potent force throughout the 12-month period,
they were especially influential in the closing months. An easing of fund
inflows in July coincided with a surge in issuance to produce a temporary
setback in the high-yield market's upward march that lasted through the first
two weeks of August, when that pattern reversed.

PERFORMANCE ANALYSIS

While the Fund participated in the market's rally, it underperformed the Lehman
Brothers U.S. Corporate High Yield Index for the 12-month period. Much of the
Fund's relative performance was driven by its lower allocation to CCC and below
rated credits, which caused the Fund to miss out on the strong performance of
this more aggressive segment of the market. We de-emphasized CCC rated credits
out of concern for the ongoing viability of many of the companies carrying that
credit rating. Our bottom-up research also led us to keep the Fund's exposure to
telecommunications and utilities companies below that of the benchmark. While we
selectively added companies in both sectors as attractive opportunities came to
market, the Fund remained underweighted to both groups during the rally.

The Fund's performance was helped by strong security selection in several key
sectors. The wireless communications sector entered the period with generally
low valuations for most of its component companies given the sector's poor
performance for most of 2002. Our analysts identified several companies that
appeared to be undervalued relative to their prospects and that went on to
perform strongly on the basis of improving financial results. The Fund also
enjoyed strong performance from securities in the diversified media and
broadcasting sectors that entered the period with low valuations and went on to
deliver solid performance. Our analysis indicated that selected companies in
economically sensitive sectors such as chemicals and manufacturing were also
undervalued, and we added exposure in these areas. This was a positive factor in
the Fund's performance during the period.

INVESTMENT STRATEGY

1.   THE FUND'S INVESTMENT TEAM BEGINS BY CONSIDERING CURRENT AND PROJECTED

     MAY INCLUDE DIRECT COMMUNICATION WITH PRINCIPALS OF INDIVIDUAL COMPANIES,
     AS WELL AS OTHER HIGH-YIELD SPECIALISTS AND RECOGNIZED RATINGS AGENCIES.

3.   LASTLY, THE FUND'S MANAGERS SEEK TO MAINTAIN BROAD DIVERSIFICATION ACROSS A
     WIDE RANGE OF COMPANIES, INDUSTRIES, COUPONS AND MATURITIES.

Notes on Performance

PRIOR TO JULY 28, 1997, THE FUND OFFERED ONLY ONE CLASS OF SHARES. BECAUSE THE
DISTRIBUTION ARRANGEMENT FOR CLASS A MOST CLOSELY RESEMBLED THE DISTRIBUTION
ARRANGEMENT APPLICABLE PRIOR TO THE IMPLEMENTATION OF MULTIPLE CLASSES (I.E.,
CLASS A IS SOLD WITH A FRONT-END SALES CHARGE), HISTORICAL PERFORMANCE
INFORMATION HAS BEEN RESTATED TO REFLECT THE ACTUAL MAXIMUM SALES CHARGE
APPLICABLE TO CLASS A (I.E., 4.25%) AS COMPARED TO THE 5.50% SALES CHARGE IN
EFFECT PRIOR TO JULY 28, 1997. IN ADDITION, CLASS A SHARES ARE NOW SUBJECT TO AN
ONGOING 12b-1 FEE WHICH IS REFLECTED IN THE RESTATED PERFORMANCE FOR THAT CLASS.

BECAUSE ALL SHARES OF THE FUND HELD PRIOR TO JULY 28, 1997 WERE DESIGNATED CLASS
D SHARES, THE FUND'S HISTORICAL PERFORMANCE HAS BEEN RESTATED TO REFLECT THE
ABSENCE OF ANY SALES CHARGE.

(1)  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. INDEXES ARE UNMANAGED AND THEIR
     RETURNS DO NOT INCLUDE ANY SALES CHARGES OR FEES. SUCH COSTS WOULD LOWER
     PERFORMANCE. IT IS NOT POSSIBLE TO INVEST DIRECTLY IN AN INDEX.

(2)  THE LIPPER HIGH CURRENT YIELD BOND FUNDS INDEX IS AN EQUALLY WEIGHTED
     PERFORMANCE INDEX OF THE LARGEST QUALIFYING FUNDS (BASED ON NET ASSETS) IN
     THE LIPPER HIGH CURRENT YIELD BOND FUNDS CLASSIFICATION. THE INDEX, WHICH
     IS ADJUSTED FOR CAPITAL GAINS DISTRIBUTIONS AND INCOME DIVIDENDS, IS
     UNMANAGED AND SHOULD NOT BE CONSIDERED AN INVESTMENT. THERE ARE CURRENTLY
     30 FUNDS REPRESENTED IN THIS INDEX.

(3)  FIGURE SHOWN ASSUMES REINVESTMENT OF ALL DISTRIBUTIONS AND DOES NOT
     REFLECTTHE DEDUCTION OF ANY SALES CHARGES.

(4)  FIGURE SHOWN ASSUMES REINVESTMENT OF ALL DISTRIBUTIONS AND THE DEDUCTION OF
     THE MAXIMUM APPLICABLE SALES CHARGE. SEE THE FUND'S CURRENT PROSPECTUS FOR
     COMPLETE DETAILS ON FEES AND SALES CHARGES.

*    THE MAXIMUM FRONT-END SALES CHARGE FOR CLASS A IS 4.25%.

**   THE MAXIMUM CONTINGENT DEFERRED SALES CHARGE (CDSC) FOR CLASS B IS 5.0%.
     THE CDSC DECLINES TO 0% AFTER SIX YEARS.

+    THE MAXIMUM CONTINGENT DEFERRED SALES CHARGE FOR CLASS C IS 1% FOR SHARES
     REDEEMED WITHIN ONE YEAR OF PURCHASE.

++   CLASS D HAS NO SALES CHARGE.

MORGAN STANLEY HIGH YIELD SECURITIES INC.
NOTES TO FINANCIAL STATEMENTS - AUGUST 31, 2003

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 following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS -- (1) certain portfolio securities may be valued by
an outside pricing service approved by the Fund's Directors; (2) fixed income
portfolio securities for which over-the-counter market quotations are readily
available are valued at the latest bid price prior to the time of valuation; (3)
an equity portfolio security listed or traded on the New York or American Stock
Exchange 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 mean between the last reported bid and asked price; (4) an equity
portfolio security listed or traded on the Nasdaq is valued at the Nasdaq
Official Closing Price; if there were no sales that day, the security is valued
at the mean between the last reported bid and asked price; (5) all other equity
portfolio securities for which over-the-counter market quotations are readily
available are valued at the mean between the last reported bid and asked price.
In cases where a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market; (6) for equity
securities traded on foreign exchanges, the last reported sale price or the
latest bid price may be used if there were no sales on a particular day; (7)
when market quotations are not readily available or Morgan Stanley Investment
Advisors Inc. (the "Investment Manager") determines that the market quotations
are not reflective of a security's market value, portfolio securities are valued
at their fair value as determined in good faith under procedures established by
and under the general supervision of the Fund's Directors; and (8) 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.

                                       23
<Page>

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 life of the
respective securities. Interest income is accrued daily except where collection
is not expected.

C. REPURCHASE AGREEMENTS -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Manager, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, U.S. Treasury or federal agency obligations. The Fund may also invest
directly with institutions in repurchase agreements. The Fund's custodian
receives the collateral, which is marked-to-market daily to determine that the
value of the collateral does not decrease below the repurchase price plus
accrued interest.

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 POLICY -- 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 -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

G. USE OF ESTIMATES -- 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.

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.

                                       24

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 will 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
Trustees will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that such excess amounts totaled
$60,327,882 at August 31, 2003.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 0.85% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Financial Advisors or other selected
broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the year ended August 31, 2003, the distribution fee was accrued for Class A
shares and Class C shares at the annual rate of 0.20% and 0.85%, respectively.

The Distributor has informed the Fund that for the year ended August 31, 2003,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class A shares, Class B shares and Class C shares of $23,338, $918,343
and $21,706, respectively and received $277,628 in front-end sales charges from
sales of the Fund's Class A shares. The respective shareholders pay such charges
which are not an expense of the Fund.

4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended August 31, 2003, aggregated
$386,219,201 and $369,664,877, respectively.

                                       25

Morgan Stanley Trust, an affiliate of the Investment Manager and Distributor, is
the Fund's transfer agent. At August 31, 2003, the Fund had transfer agent fees
and expenses payable of approximately $20,000.

The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Directors of the Fund who will have served as independent
Directors for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended August 31, 2003 included
in Directors' fees and expenses in the Statement of Operations amounted to
$13,434. At August 31, 2003, the Fund had an accrued pension liability of
$57,234 which is included in accrued expenses in the Statement of Assets and
Liabilities.

An affiliated company is a company in which the Fund has ownership of at least
5% of the voting securities. Transactions with such companies during the year
ended August 31, 2003 were as follows:

7. FEDERAL INCOME TAX STATUS
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

distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.

*As of August 31, 2003, the Fund had a net capital loss carryforward of
$1,072,223,163 of which $27,363,677 will expire on August 31, 2004, $42,577,150
will expire on August 31, 2005, $15,861,101 will expire on August 31, 2006,
$28,176,968 will expire on August 31, 2007, $73,114,566 will expire on August
31, 2008, $92,557,036 will expire on August 31, 2009, $224,095,251 will expire
on August 31, 2010 and $568,477,414 will expire on August 31, 2011 to offset
future capital gains to the extent provided by regulations.

As part of the Fund's acquisition of the assets of Morgan Stanley High Income
Advantage Trusts I, II and III (the "HIATs"), the Fund obtained a net capital
loss carryforward of $231,274,856 from the HIATs. Utilization of this
carryforward is subject to limitations imposed by the Internal Revenue Code and
Treasury Regulations, reducing the total carryforward available.

As of August 31, 2003, the Fund had temporary book/tax differences primarily
attributable to post-October losses (capital losses incurred after October 31
within the taxable year which are deemed to arise on the first business day of
the Fund's next taxable year), interest on bonds in default and book
amortization of discounts on debt securities and permanent book/tax differences
primarily attributable to tax adjustments on debt securities sold by the Fund
and capital loss carryforwards expired or written off by the Fund. To reflect
reclassifications arising from the permanent differences, paid-in-capital was
charged $318,746,954, accumulated undistributed net investment income was
credited $10,205,488 and accumulated net realized loss was credited
$308,541,466.

MORGAN STANLEY HIGH YIELD SECURITIES INC.
INDEPENDENT AUDITORS' REPORT


TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF
MORGAN STANLEY HIGH YIELD SECURITIES INC.:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley High Yield Securities Inc. (the "Fund"), including the portfolio of
investments, as of August 31, 2003, and the related statements of operations for
the year then ended and changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of August 31, 2003, by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Morgan
Stanley High Yield Securities Inc. as of August 31, 2003, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

functions, regardless of whether these individuals are employed by the Fund or a
third party.

Item 3.  Audit Committee Financial Expert.

The Fund's Board of Directors has determined that it has two "audit committee
financial experts" serving on its audit committee, each of whom are
"independent" Directors: Dr. Manuel H. Johnson and Joseph J. Kearns. Under
applicable securities laws, a person who is determined to be an audit
committee financial expert will not be deemed an "expert" for any purpose,
including without limitation for the purposes of Section 11 of the Securities
Act of 1933, as a result of being designated or identified as an audit
committee financial expert. The designation or identification of a person as
an audit committee financial expert does not impose on such person any
duties, obligations, or liabilities that are greater than the duties,
obligations, and liabilities imposed on such person as a member of the audit
committee and Board of Directors in the absence of such designation or
identification.
