MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND         Two World Trade Center,
LETTER TO THE SHAREHOLDERS September 30, 1999         New York, New York 10048


DEAR SHAREHOLDER:

The twelve-month period ended September 30, 1999, saw the U.S. equity market
rally to record highs as the U.S. economy continued its strength and
international stock markets soared on improving economic conditions overseas,
especially in southeast Asia and Japan. After a peak in the domestic markets in
the middle of July, stock prices pulled back toward the end of the period amid
concerns that the U.S. economy might be growing too fast. This concern was
manifested in two Federal Reserve Board moves, in June and August, that raised
the federal-funds rate a total of 50 basis points while inflation remained low
and the economy continued to grow.


PERFORMANCE AND PORTFOLIO STRATEGY

During the twelve-month period ended September 30, 1999, Morgan Stanley Dean
Witter Income Builder Fund's Class B shares produced a total return of 9.31
percent, compared with 13.36 percent for the Lipper Equity Income Funds Index
and 27.79 percent for the S&P 500 Composite Stock Price Index (S&P 500). For
the same period, the Fund's Class A, C and D shares posted total returns of
10.15 percent, 9.38 percent and 10.51 percent, respectively. The performance of
the Fund's four share classes varies because of differing expenses. (The total
return figures shown assume the reinvestment of all distributions and do not
reflect the deduction of any applicable sales charges.) The accompanying chart
illustrates the performance of the Fund versus the S&P 500 and Lipper indexes.

The Fund's underperformance relative to its benchmark indexes can be attributed
largely to its lack of exposure to technology stocks, which generally pay
little if any dividends. Because the Fund's primary objective is providing
reasonable current income, these stocks are not included in the portfolio. The
Fund's value-oriented style of stock selection has also hindered its relative
performance versus the S&P 500. In recent years the S&P 500, the benchmark
against which most equity funds are compared,
<PAGE>

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
LETTER TO THE SHAREHOLDERS September 30, 1999, continued

has reflected a bias toward growth, with companies like Microsoft, Intel, Dell
and Cisco being heavily weighted in the index.

On September 30, 1999, the Fund's large-cap stock segment was relatively fully
invested, as it has been since the Fund's inception. Portfolio transactions
during the fiscal year included the sale of Edison International, New England
Electric System, Aegon N.V., Providian Financial Corp., Cyprus Amax Minerals
Company, First Security Corp., Keycorp, American Greetings, U.S. West and
Wilmington Trust. Purchases included Armstrong World Industries, Teco Energy,
Conseco, Tidewater, Ryder, Fluor, Ultramar Diamond Shamrock and Xerox.

Real estate investment trusts (REITs) continued their poor performance during
the fiscal year. While growth rates have slowed from their peaks in the mid
1990s, industry fundamentals have stabilized and are beginning to improve.
Dividends are increasing as companies are forced to pay out more of their
operating income as a result of their REIT structure, and many companies have
stock buyback plans in place. We believe the REIT market is attractively valued
currently and have committed 10 percent of the Fund's net assets to this
sector.


LOOKING AHEAD

We believe that the long-term outlook for the financial markets is positive. In
the year ahead we believe growth in earnings will continue to help drive stocks
upward. However, this may occur against a backdrop of rising interest rates,
resulting in higher market volatility. We believe the Fund is well positioned
to take advantage of the positive aspects of this financial climate, because of
its value-oriented style and its emphasis on higher-yielding securities.

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



Very truly yours,


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

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
NOTES TO FINANCIAL STATEMENTS September 30, 1999


1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Income Builder Fund (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 seek reasonable income and, as a secondary objective, growth of capital.
The Fund seeks to achieve its objective by investing primarily in
income-producing equity securities, including common and preferred stocks as
well as convertible securities. The Fund was organized as a Massachusetts
business trust on March 21, 1996 and commenced operations on June 26, 1996. On
July 28, 1997, the Fund converted to a multiple class 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 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 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 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 approved by the Trustees. The pricing service may


                                       19
<PAGE>

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
NOTES TO FINANCIAL STATEMENTS September 30, 1999, continued

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 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
except for certain dividends on 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. 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 ex-dividend date. The amounts 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.

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
NOTES TO FINANCIAL STATEMENTS September 30, 1999, continued

F. ORGANIZATIONAL EXPENSES -- The Investment Manager paid the organizational
expenses of the Fund in the amount of approximately $164,000 which have been
reimbursed for the full amount thereof. Such expenses have been deferred and
are being amortized on the straight-line method over a period not to exceed
five years from the commencement of operations.


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 $500
million and 0.725% to the portion of daily net assets in excess of $500
million.

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 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, 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


                                       21
<PAGE>

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
NOTES TO FINANCIAL STATEMENTS September 30, 1999, continued

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 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 $17,141,308 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 year 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
0.97%, respectively.

The Distributor has informed the Fund that for the year ended September 30,
1999, it received contingent deferred sales charges from certain redemptions of
the Fund's Class B shares and Class C shares of $1,174,157 and $4,337,
respectively and received $15,164 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 September 30, 1999
aggregated $149,965,342 and $248,758,198, respectively.

NOTES TO FINANCIAL STATEMENTS September 30, 1999, continued

For the year ended September 30, 1999, the Fund incurred $131,414 in brokerage

5. FEDERAL INCOME TAX STATUS

differences, accumulated undistributed net investment income was charged
$276,423, paid-in-capital was charged $32,710 and accumulated net realized gain

MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND
REPORT OF INDEPENDENT ACCOUNTANTS


TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER INCOME BUILDER FUND

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Morgan Stanley Dean Witter Income
Builder Fund (the "Fund") at September 30, 1999, 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
periods presented, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits, which included confirmation of
securities at September 30, 1999 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinion expressed above.
