LETTER TO THE SHAREHOLDERS SEPTEMBER 30, 1999

DEAR SHAREHOLDER:

The six-month period ended September 30, 1999 may have marked the beginning of a
new period of outperformance by the international equity markets. After several
years of strong returns from the U.S. stock market, events of the last six
months suggest a change in leadership may be afoot. Not only have emerging
markets performed well, but many developed markets in Europe and Asia have
outperformed also. While the factors that drive the direction of stock prices
are constantly changing, we remain optimistic about the favorable long-term
prospects for the high-quality companies sought out by Morgan Stanley Dean
Witter Global Dividend Growth Securities.

PERFORMANCE

For the six-month period ended September 30, 1999, the Fund's Class B shares
posted a total return of 7.86 percent, compared with 3.39 percent for the Morgan
Stanley Capital International World Index (MSCI World Index) and 5.82 percent
for the Lipper Global Fund Index. During the same period, the Fund's Class A, C
and D shares posted total returns of 8.13 percent, 7.69 percent and 8.32
percent, respectively. The performance of the Fund's four share classes varies
because each class has different expenses. (Total return figures shown assume
the reinvestment of all distributions and do not reflect the deduction of any
applicable sales charges.)

The Fund's emphasis on perceived high-quality industry leaders and its
disciplined management style proved advantageous during this somewhat volatile
period, as the Fund significantly outperformed both its benchmark index and
Lipper peer group.

THE UNITED STATES

The U.S. equity market lagged other world markets in the last six months. The
Standard & Poor's 500 Composite Stock Price Index (S&P 500) was up 0.37 percent
compared to 7.18 percent for the MSCI

Europe, Australia and Far East (EAFE) index. As the world's largest economy, the
U.S. continues to represent the largest portion of the Fund's portfolio, with 31
percent of the Fund's net assets targeted toward U.S. stocks. This represents a
significant underweighting of the U.S. relative to its 50 percent weighting in
the MSCI World Index. With U.S. equity valuations near all-time highs on most
measures, we have taken the opportunity to sell some U.S. equity holdings,
further reducing our U.S. exposure. This move has proved fortuitous in the last
six months and we believe non-U.S. markets are likely to continue to perform
better in the near future.

JAPAN

The Japanese equity market tops the list as the world's best-performing
developed-country market in which the Fund was invested during the period under
review. The MSCI Japan Index returned 24.7 percent in U.S. dollars, far
exceeding most investors' expectations.

One year ago, we described the extreme level of pessimism evident among Japanese
consumers and business people. Many measures of economic activity highlighted
the severely depressed state of the Japanese economy and many observers warned
of a deflationary spiral. We also wrote that during periods of extreme
pessimism, opportunities exist to buy some of the world's greatest companies for
very attractive prices. For the disciplined long-term investor willing to look
through the haze of uncertainty, there were indeed exciting opportunities.
Acting on this belief helped the Fund achieve its favorable performance results
during the period under review, as it had 15.5 percent of its net assets
targeted toward Japan at the end of September. This is slightly less than the 17
percent allocation toward Japan six months ago, but as that market has performed
so strongly, the Fund realized significant profits by reducing its exposure.

It is becoming increasingly clear that Japan is well on its way toward economic
improvement. The first two quarters of this fiscal year witnessed strong
positive GDP growth and Japanese industrial production growth saw its largest
monthly improvement in nearly 50 years. Reorganization of the country's banking
system is clearly positive and we anticipate a significant upswing in corporate
profits on better consumer demand and corporate restructuring efforts. Recent
strength in the Japanese yen reinforces the need for further corporate
restructuring.

Despite Japan's strong performance, the equity market remains 45 percent below
its all-time high recorded nearly ten years ago. As the Japanese economy
continues to improve, corporate profits recover and the pessimism subsides, we
expect the stocks of Japan's highest quality companies to be driven higher by
investors. The Fund is well positioned to benefit from such circumstances.
Overall, we remain optimistic about the long-term prospects for the Fund's
Japanese holdings.

EUROPE

Once again, we believe Europe presents great opportunities for the disciplined
long-term investor. After a period of relatively weak economic growth, signs are
emerging that Europe's economy is poised for a takeoff. Anticipated strong
corporate profits growth and a continuing benign inflation outlook should help
drive many European stocks higher. Furthermore, merger activity in Europe is
very strong, particularly in many of the large companies in which the Fund is
invested, and increasingly involves cross-border partnerships. The arrival of
Europe's single currency, the euro, on January 1, 1999, has facilitated many of
these mergers. As Europe's economy gathers momentum relative to the United
States, we expect the euro to appreciate versus the U.S. dollar, also favorable
for U.S.-based investors in European equities. At period end the Fund had 25
percent of its net assets targeted toward the eleven countries that together
form the eurozone, a four percent increase from six months earlier.

Other continental European markets where the Fund maintains exposure include
Switzerland (6 percent) and Sweden (1.5 percent). The combination of low
interest rates, strong corporate profits growth and attractive valuations should
support Swiss equities in the near term. The Fund's Swedish exposure was
recently reduced due to strong performance and better relative opportunities
elsewhere.

The Fund had 14 percent of its net assets invested in the United Kingdom at the
end of September, a 3 percent increase over six months earlier. Despite the
recent hike in short-term interest rates by the Bank of England, inflation
appears subdued and further rate increases are unlikely in the near term. We
believe the long-term prospects for U.K. equities are quite favorable, supported
by compelling valuations in many sectors and an improving corporate profit
outlook. Recent additions to the Fund include Rolls Royce and Abbey National
Bank.

PACIFIC RIM

Because of the Fund's risk considerations, Hong Kong is the only Southeast Asian
market in which the Fund is currently invested. Most Asian stock markets have
rebounded strongly from their depressed levels of one year ago, and Hong Kong
stocks have not been an exception, advancing more than 15.6 percent over the
last six months and more than 60 percent in the last twelve months. GDP growth
in Hong Kong registered a 0.7 percent year-over-year gain in the second quarter
of 1999 after declining in five consecutive quarters. Real estate prices have
recovered, as has private consumption. The Fund had 1.7 percent of net assets in
Hong Kong as of September 30, down from

2.0 percent six months earlier. Much of Asia's recovery seems well discounted by
current equity prices, but we are convinced that further strength in Asian
economies and equity markets is forthcoming.

CANADA AND AUSTRALIA

Our continued exposure to the resource-oriented markets of Australia and Canada
offers the potential for risk reduction through diversification as well as
growth potential in economically stable countries. After a long period of
declining commodity prices, the resurgence in global economic activity has
driven prices of some commodities higher. If this increased global demand
persists, companies that manufacture and process commodities and natural
resources should benefit.

LOOKING AHEAD

We believe that as global economic growth accelerates and becomes more evenly
distributed, the outlook for stocks of well-established large-capitalization
international companies is favorable. We believe this is a very good time to
participate in the global equity markets and we will remain sensitive to any
developments that would necessitate a change to the Fund's country allocations
and portfolio holdings.

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

Very truly yours,

MORGAN STANLEY DEAN WITTER GLOBAL DIVIDEND GROWTH SECURITIES
NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 1999 (UNAUDITED)

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Global Dividend Growth Securities (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 provide reasonable current income and long-term growth of income
and capital. The Fund seeks to achieve its objective by investing primarily in
common stock of issuers worldwide, with a record of paying dividends and the
potential for increasing dividends. The Fund was organized as a Massachusetts
business trust on January 12, 1993 and commenced operations on June 30, 1993. 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 securities are traded on more than one exchange, the securities are
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price 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

                                       16
<PAGE>
MORGAN STANLEY DEAN WITTER GLOBAL DIVIDEND GROWTH SECURITIES
NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 1999 (UNAUDITED) CONTINUED

prices of securities which are comparable in coupon, rating and maturity or an
appropriate matrix utilizing similar factors); and (4) 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
except for certain dividends from foreign securities which are recorded as soon
as the Fund is informed after 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. FOREIGN CURRENCY TRANSLATION -- The books and records of the Fund are
maintained in U.S. dollars as follows: (1) the foreign currency market value of
investment securities, other assets and liabilities and forward foreign currency
contracts are translated at the exchange rates prevailing at the end of the
period; and (2) purchases, sales, income and expenses are translated at the
exchange rates prevailing on the respective dates of such transactions. The
resultant exchange gains and losses are included in the Statement of Operations
as realized and unrealized gain/loss on foreign exchange transactions. Pursuant
to U.S. Federal income tax regulations, certain foreign exchange gains/losses
included in realized and unrealized gain/loss are included in or are a reduction
of ordinary income for federal income tax purposes. The Fund does not isolate
that portion of the results of operations arising as a result of changes in the
foreign exchange rates from the changes in the market prices of the securities.

E. FORWARD FOREIGN CURRENCY CONTRACTS -- The Fund may enter into forward foreign
currency contracts which are valued daily at the appropriate exchange rates. The
resultant unrealized exchange gains and losses are included in the Statement of
Operations as unrealized gain/loss on

                                       17
<PAGE>
MORGAN STANLEY DEAN WITTER GLOBAL DIVIDEND GROWTH SECURITIES
NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 1999 (UNAUDITED) CONTINUED

foreign exchange transactions. The Fund records realized gains or losses on
delivery of the currency or at the time the forward contract is extinguished
(compensated) by entering into a closing transaction prior to delivery.

F. 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.

G. 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, the Fund pays the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined at the close of
each business day: 0.75% to the portion of daily net assets not exceeding $1
billion; 0.725% to the portion of daily net assets exceeding $1 billion but not
exceeding $1.5 billion; 0.70% to the portion of daily net assets exceeding $1.5
billion but not exceeding $2.5 billion; 0.675% to the portion of daily net
assets exceeding $2.5 billion but not exceeding $3.5 billion; 0.65% to the
portion of daily net assets exceeding $3.5 billion but not exceeding
$4.5 billion; and 0.625% to the portion of daily net assets in excess of $4.5
billion.

Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, office space, facilities, equipment,
clerical, bookkeeping and certain legal services and pays the salaries of

                                       18

MORGAN STANLEY DEAN WITTER GLOBAL DIVIDEND GROWTH SECURITIES

all personnel, including officers of the Fund who are employees of the
Investment Manager. The Investment Manager also bears the cost of telephone
services, heat, light, power and other utilities provided to the Fund.

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 A shares, amounts paid under the Plan
are paid to the Distributor for services provided. In the case of Class B and
Class C shares, amounts paid under the Plan are paid to the Distributor for (1)
services provided and the expenses borne by it and others in the distribution of
the shares of these Classes, including the payment of commissions for sales of
these Classes and incentive compensation to, and expenses of, the Morgan Stanley
Dean Witter Financial Advisors and others who engage in or support distribution
of the shares or who service shareholder accounts, including overhead and
telephone expenses; (2) printing and distribution of prospectuses and reports
used in connection with the offering of these shares to other than current
shareholders; and (3) preparation, printing and distribution of sales literature
and advertising materials. In addition, the Distributor may utilize fees paid
pursuant to the Plan, in the case of Class B shares, to compensate Dean Witter
Reynolds Inc. ("DWR"), an affiliate of the Investment Manager and Distributor,
and other selected broker-dealers for their opportunity costs in advancing such
amounts, which compensation would be in the form of a carrying charge on any
unreimbursed expenses.

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

                                       19

MORGAN STANLEY DEAN WITTER GLOBAL DIVIDEND GROWTH SECURITIES

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, including carrying charges, totaled
$64,953,906 at September 30, 1999.

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, 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 September 30, 1999, the distribution fee
was accrued for Class A shares and Class C shares at the annual rate of 0.24%
and 1.00%, respectively.

The Distributor has informed the Fund that for the six months ended
September 30, 1999, it received contingent deferred sales charges from certain
redemptions of the Fund's Class A, Class B and Class C shares of $64, $1,813,110
and $2,807, respectively and received $38,257 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 September 30, 1999 aggregated
$806,369,334 and $1,018,272,434, respectively.

For the six months ended September 30, 1999, the Fund incurred $28,347 in
brokerage commissions with DWR for portfolio transactions executed on behalf of
the Fund.

For the six months ended September 30, 1999, the Fund incurred brokerage
commissions of $555,445 with Morgan Stanley & Co., Inc., an affiliate of the

investments sold were unsettled trades with Morgan Stanley & Co., Inc. for
$2,419,602.

Morgan Stanley Dean Witter Trust FSB, an affiliate of the Investment Manager and
Distributor, is the Fund's transfer agent.

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

                                       20

6. FEDERAL INCOME TAX STATUS

As of March 31, 1999, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales and income from the
mark-to-market of passive foreign investment companies.

7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS

The Fund may enter into forward foreign currency contracts ("forward contracts")
to facilitate settlement of foreign currency denominated portfolio transactions
or to manage foreign currency exposure associated with foreign currency
denominated securities.

Forward contracts involve elements of market risk in excess of the amounts
reflected in the Statement of Assets and Liabilities. The Fund bears the risk of
an unfavorable change in the foreign exchange rates underlying the forward
contracts. Risks may also arise upon entering into these contracts from the
potential inability of the counterparties to meet the terms of their contracts.

At September 30, 1999, there were outstanding forward contracts used to
facilitate settlement of foreign currency denominated portfolio transactions.
