MORGAN STANLEY DEAN WITTER HIGH YIELD SECURITIES INC.  TWO WORLD TRADE CENTER,
LETTER TO THE SHAREHOLDERS, AUGUST 31, 2000            NEW YORK, NEW YORK 10048

DEAR SHAREHOLDER:

The 12-month period ended August 31, 2000, proved to be an extremely difficult
one for high-yield bond investors, as the high-yield market remained mired in
one of its worst slumps in the past 20 years. Concern over a rapidly growing
U.S. economy and the threat of inflation prompted the Federal Reserve Board to
continue its policy of raising short-term interest rates. As a result of the
Fed's actions and the ensuing higher-interest-rate environment, the financial
markets became worried about a potential hard landing for the U.S. economy and
its effect on future corporate earnings. These fears resulted in an extremely
weak fixed-income market during 1999 and an increasingly volatile equity market
in the first half of 2000. As investors became more risk averse, we witnessed a
severe flight to quality in the fixed-income markets, with the high-yield sector
being hit exceptionally hard. Much as in the last major high-yield market
correction ten years ago, significant investor outflows have greatly exaggerated
the decline, creating an extremely oversold market.

Credit spreads within the fixed-income markets widened dramatically over the
past year and a half as investors came to favor higher-quality securities. As a
result of this flight to quality, the yield spread between high-yield bonds and
comparable U.S. government securities is now approaching its widest margin in
history. Spreads have also broadened between the different tiers within the
high-yield sector as investors have gravitated toward the highest-quality end of
the marketplace. As a result of this trend, lower-yielding, higher-quality
BB-rated bonds have held up significantly better than those in the
higher-yielding, lower-quality B-rated sector. Much as we saw in the high-yield
bear market of 1989 and 1990, investors' reactions have resulted in a sharp
decline in the prices of many high-yield bonds, driving market yields
substantially higher in the process so that yield spreads on many B-rated bonds
are approaching their highest levels on record.

PERFORMANCE

During the twelve-month period ended August 31, 2000, Morgan Stanley Dean Witter
High Yield Securities' Class A and D shares produced returns of -8.88 percent
and -8.69 percent, respectively. The Fund underperformed the Lehman Brothers
U.S. Corporate High Yield Index, which returned 1.13 percent. For the same
period, the Fund's Class B and C shares had total returns of -9.39 percent and
-9.66 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.

The Fund's underperformance relative to its benchmark was due primarily to focus
on the B-rated sector of the high-yield market. As outlined above, B-rated
securities sharply underperformed the higher-quality end of the high-yield
market.

PORTFOLIO STRATEGY

As discussed, the past year and a half has been one of the most difficult
periods for the high-yield market, particularly the B-rated sector, the market's
largest one. As a result of the substantial weakness in the high-yield market,
we have seen high-yield bond prices decline sharply and yields rise dramatically
over this period. Although the Fund's position in the more defensive,
higher-quality end of the market held up relatively well in the turbulent market
environment, its long-term core position in the B-rated sector was adversely
affected over the past year. With prices on many high-yield issues at or near
10-year lows and currently trading at significant discounts to their stated
maturity value, we currently view the high-yield sector as extremely
undervalued, although the timing of a recovery is still very uncertain at this
point. As the market outlook improves over time, we would expect to see investor
flows turn positive once again, creating strong demand for many of today's
depressed high-yield bonds. In light of our positive long-term outlook based on
historically low valuations, we are maintaining our focus on this sector of the
market, which we believe offers the Fund long-term total return potential.

From an industry perspective we view the telecommunications sector as a
potentially rewarding investment opportunity, given the worldwide movement
toward providing expanded global telecommunications services, including voice,
video and data services over a combination of hardline and wireless networks.
The powerful combination of exciting growth prospects for the industry over the
next few years, along with the likelihood of the formation of strategic
partnerships with other major

players, provides a fundamental backdrop for strong revenue growth, higher
profitability and future significant credit improvement. Included among the
Fund's current holdings are a number of telecom companies that over the past
year have either announced important strategic partnerships or have raised
equity capital to fuel future growth and profits. With the recent high-yield
market weakness we have seen many of these telecom bonds decline sharply in
price as investor nervousness spread to this large but volatile sector of the
market. Despite the recent sector weakness, we view the longer-term prospects of
this important industry very positively and feel that at today's depressed
levels many of these bonds represent outstanding investment opportunities.

LOOKING AHEAD

In light of today's substantially higher yields, near-record yield spreads over
U.S. government bonds and significantly discounted bond prices, we view the
high-yield market as a potentially rewarding long-term investment opportunity.
Assuming a soft landing in the economy with growth continuing into 2001, we
would expect the high-yield market to recover over time and bond prices to
rebound from their current extremely depressed levels, much as they did in the
early 1990s period following the last high-yield bear market. Although the
B-rated segment of the market has clearly not been a good investment performer
over the past 18 months, we remain confident that its attractive yield and
capital appreciation potential remain intact for long-term investors.

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

Very truly yours,

1. ORGANIZATION AND ACCOUNTING POLICIES

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

                                       19

MORGAN STANLEY DEAN WITTER HIGH YIELD SECURITIES INC.
NOTES TO FINANCIAL STATEMENTS AUGUST 31, 2000, CONTINUED

by the Directors. The pricing service may utilize a matrix system incorporating
security quality, maturity and coupon as the evaluation model parameters, and/or
research and evaluations by its staff, including review of broker-dealer market
price quotations, if available, in determining what it believes is the fair
valuation of the portfolio securities valued by such pricing service; and
(5) short-term debt securities having a maturity date of more than sixty days at
time of purchase are valued on a mark-to-market basis until sixty days prior to
maturity and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.

C. 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.

D. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.

E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax" differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary

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 Dean Witter Distributors
Inc. (the "Distributor"), an affiliate of the Investment Manager. The Fund has
adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1 under the
Act. The Plan provides that the Fund 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
$59,549,106 at August 31, 2000.

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 Dean Witter Financial Advisors or

other selected broker-dealer representatives may be reimbursed in the subsequent
calendar year. For the year ended August 31, 2000, 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, 2000,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class A Shares, Class B shares and Class C shares of $26,734, $4,887,041
and $86,304, respectively and received $187,035 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.

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 $11,629,000 during fiscal 2000.

At August 31, 2000, 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 and permanent book/tax differences primarily
attributable to an expired capital loss carryover. To reflect reclassifications
rising from the permanent differences, paid-in-capital was charged $182,217,561,
accumulated net realized loss was credited $182,201,073 and dividends in excess
of net investment income was credited $16,488.

MORGAN STANLEY DEAN WITTER HIGH YIELD SECURITIES INC.
INDEPENDENT AUDITORS' REPORT

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
MORGAN STANLEY DEAN WITTER HIGH YIELD SECURITIES:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Dean Witter High Yield Securities (the "Fund") including the portfolio
of investments, as of August 31, 2000, and the related statements of operations
and changes in net assets, and the financial highlights for the year 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 audit. The statement
of changes in net assets for the year ended August 31, 1999 and the financial
highlights for each of the respective stated periods ended August 31, 1999 were
audited by other independent accountants whose report, dated October 8, 1999,
expressed an unqualified opinion on that statement and financial highlights.

We conducted our audit 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 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, 2000, by correspondence with the custodian. 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 audit provides 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 Dean Witter High Yield Securities as of August 31, 2000, the results of
its operations, the changes in its net assets, and the financial highlights for
the year then ended, in conformity with accounting principles generally accepted
in the United States of America.

MORGAN STANLEY DEAN WITTER HIGH YIELD SECURITIES INC.
CHANGE IN INDEPENDENT ACCOUNTANTS

On July 1, 2000 PricewaterhouseCoopers LLP resigned as independent accountants
of the Fund.

The reports of PricewaterhouseCoopers LLP on the financial statements of the
Fund for the past two fiscal years contained no adverse opinion or disclaimer of
opinion and were not qualified or modified as to uncertainty, audit scope or
accounting principle.

In connection with its audit for the two most recent fiscal years and through
July 1, 2000, there have been no disagreements with PricewaterhouseCoopers LLP
on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements if not resolved
to the satisfaction of PricewaterhouseCoopers LLP would have caused them to make
reference thereto in their report on the financial statements for such years.

The Fund, with the approval of its Board of Directors and its Audit Committee,
engaged Deloitte & Touche LLP as its new independent accountants as of July 1,
2000.
