MORGAN STANLEY DEAN WITTER CONVERTIBLE SECURITIES TRUST Two World Trade Center
LETTER TO THE SHAREHOLDERS March 31, 2000 New York, New York 10048
DEAR SHAREHOLDER:
During the six-month period ended March 31, 2000, investors witnessed
unprecedented appreciation in the technology-laden Nasdaq, while stocks of more
traditional companies suffered from slowing growth rates and capital outflows
before surging upward toward the end of the period. Correctly assuming that the
Y2K computer bug would cause little disruption, investors bid up technology
stocks in anticipation of strong corporate spending and consumer demand in 2000.
Access to inexpensive capital through private and public equity as well as the
convertible market enabled high-growth companies to fund their business plans
with little impact from rising interest rates. Buoyed by heavy new issuance and
strong performance from technology and telecommunications stocks, convertibles
outperformed the broader equity markets during the period.
PERFORMANCE
For the six-month period ended March 31, 2000, Morgan Stanley Dean Witter
Convertible Securities Trust's Class B shares posted a total return of 34.54
percent compared to 19.18 percent for the Goldman Sachs Convertible 100 Index*.
For the same period, the Fund's Class A, C and D shares returned 35.15 percent,
34.55 percent and 35.27 percent, respectively. The performance of the Fund's
four share classes varies because of differing expenses. The total return
figures given assume the reinvestment of all distributions but do not reflect
the deduction of any applicable sales charges.
The Fund's core positions in the Internet infrastructure, semiconductor and
telecommunications sectors all contributed positively to its outperformance
during the period. Participation in the primary market also benefited the Fund,
because convertible financing catalyzed the stocks of many entrants new to the
convertible universe. Investments in

weighted convertible issues with market capitalizations of at least $100
million. The Index does not include any expenses, fees or charges. The Index is

LETTER TO THE SHAREHOLDERS March 31, 2000, continued
biotechnology also proved highly profitable for the Fund because of excitement
surrounding the sequencing of the human genome, though in recent weeks these
stocks have given back much of their gains.
PORTFOLIO STRATEGY
The Fund uses a growth-oriented, bottom-up approach to evaluate companies and
determine their investment merits, seeking to identify companies and sectors
with strong underlying fundamentals and solid long-term growth potential. Over
the course of the past year we have increased the Fund's exposure to the
technology and telecommunications sectors to better reflect the composition of
the convertible universe, maintaining overweighted or underweighted positions
based on the outlook we held for various industries. The addition of
high-quality large-cap issues has also improved the Fund's credit profile while
offering substantial equity participation. As of March 31, 2000, the Fund had
exposure to 47 different industries and maintained a weighting of approximately
25 percent in equities.
In attempting to control volatility, the Fund generally concentrates on issues
with shorter maturities while diversifying its assets across a wide range of
industries. The Fund also searches for convertible securities with good
risk/reward characteristics. These traits include relatively high yield, to
support the convertible if the underlying stock declines, and reasonable
conversion premiums to ensure participation in any appreciation of the
underlying stock.
LOOKING AHEAD
Despite the significant gains made by convertibles during the period, we believe
the market remains highly attractive from a risk/reward perspective. It is our
expectation that convertibles can perform well over the long run, offering
potentially competitive returns in modestly increasing, stable or declining
equity markets, though they may tend to lag equities during very strong periods.
We appreciate your ongoing support of Morgan Stanley Dean Witter Convertible
Securities Trust and look forward to continuing to serve your investment needs.

NOTES TO FINANCIAL STATEMENTS March 31, 2000 (unaudited)
1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Dean Witter Convertible Securities Trust (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 investment
objective is to seek a high level of total return on its assets through a
combination of current income and capital appreciation. The Fund was organized
as a Massachusetts business trust on May 21, 1985 and commenced operations on
October 31, 1985. 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 security listed or traded on the
New York, American or other domestic or foreign stock exchange is valued at its
latest sale price on that exchange prior to the time when assets are valued; if
there were no sales that day, the security is valued at the latest bid price (in
cases where a security is traded on more than one exchange, the security is
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Morgan Stanley Dean Witter 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 (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
15
<PAGE> 16
MORGAN STANLEY DEAN WITTER CONVERTIBLE SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS March 31, 2000 (unaudited) continued
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 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.
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
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.

2. INVESTMENT MANAGEMENT AGREEMENT
Pursuant to an Investment Management Agreement with the Investment Manager, the
Fund pays the Investment Manager a management fee, accrued daily and payable
monthly, by applying the following annual rates to the Fund's net assets
determined as of the close of each business day: 0.60% to the portion of the
daily net assets not exceeding $750 million; 0.55% to the portion of the daily
net assets exceeding $750 million but not exceeding $1 billion; 0.50% to the
portion of daily net assets exceeding $1 billion but not exceeding $1.5 billion;
0.475% to the portion of daily net assets exceeding $1.5 billion but not
exceeding $2 billion; 0.45% to the portion of daily net assets exceeding $2
billion but not exceeding $3 billion; and 0.425% 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 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 -- 1.0% of the
lesser of: (a) the average daily aggregate gross sales of the Class B shares
since the inception of the Fund (not including reinvestment of dividend or
capital gain distributions) less the average daily aggregate net asset value of
the Class B shares redeemed since the Fund's inception upon which a contingent
deferred sales charge has been imposed or waived; or (b) the average daily net
assets of Class B; and (iii) Class C -- up to 1.0% 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
$85,109,446 at March 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 1.0% of the average daily
net assets of Class A or Class C,
17
<PAGE> 18
MORGAN STANLEY DEAN WITTER CONVERTIBLE SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS March 31, 2000 (unaudited) continued
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 six
months ended March 31, 2000, the distribution fee was accrued for Class A shares
and Class C shares at the annual rate of 0.23% and 0.99%, respectively.
The Distributor has informed the Fund that for the six months ended March 31,
2000, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and Class C shares of $121,407 and $77, respectively
and received $6,676 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 six months ended March 31, 2000 aggregated
$232,435,311 and $236,750,586, respectively.
For the six months ended March 31, 2000, the Fund incurred brokerage commissions
of $500 with Dean Witter Reynolds Inc., an affiliate of the Investment Manager
and Distributor, for portfolio transactions executed on behalf of the Fund.
For the six months ended March 31, 2000, the Fund incurred brokerage commissions
of $1,178 with Morgan Stanley & Co., Inc., an affiliate of the Investment
Manager and Distributor, for portfolio transactions executed on behalf of the
Fund.
Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent. At March 31, 2000, the Fund had
transfer agent fees and expenses payable of approximately $7,000.
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund 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 six months ended March 31, 2000
included in Trustees' fees and expenses in the Statement of Operations amounted
to $2,923. At March 31, 2000, the Fund had an accrued pension liability of
$52,827 which is included in accrued expenses in the Statement of Assets and
Liabilities.

5. FEDERAL INCOME TAX STATUS
At September 30, 1999, the Fund had a net capital loss carryover of
approximately $65,250,000 of which $62,731,000 will be available through
September 30, 2000 and $2,519,000 will be available through September 30, 2007
to offset future capital gains to the extent provided by regulations.
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 $7,244,000 during fiscal 1999. As of September 30, 1999, the Fund
had temporary book/tax differences primarily attributable to post-October
losses.
