MORGAN STANLEY DEAN WITTER TOTAL MARKET INDEX FUND       Two World Trade Center,
LETTER TO THE SHAREHOLDERS July 31, 2000                New York, New York 10048

DEAR SHAREHOLDER:

This year's stock market continues to reverse trends established in 1999. In
contrast to prior periods, the large-cap segment of the U.S. equity market has
underperformed the mid-cap and small-cap market segments. Recent interest rate
hikes by the Federal Reserve Board have helped dissipate fears of growing
inflation but at the same time have forced investors to rethink the notions of
economic perfection that had been priced into the market. As a result,
technology, last year's favorite sector, has generated only modest returns over
the last six months and trails more defensive issues such as the utilities and
health-care sectors.

FUND PERFORMANCE

Since its inception on September 28, 1999, through July 31, 2000, Morgan Stanley
Dean Witter Total Market Index Fund's Class A, B, C and D shares produced total
returns of 13.99 percent, 13.29 percent, 13.29 percent and 14.30 percent,
respectively. During the same period, the Wilshire 5000 Total Market Index
(Wilshire 5000) returned 15.05 percent. The performance of the Fund's four share
classes varies because of differing expenses. Total return figures assume the
reinvestment of all distributions but do not reflect the deduction of any
applicable sales charges.

The Fund seeks to provide investment results that correspond, before expenses,
to the total return (i.e., the combination of capital change and income) of the
Wilshire 5000. The Fund seeks to achieve this objective by investing in a
representative sampling of companies that comprise the index. The Wilshire 5000
is widely considered to provide the best representation of the overall U.S.
market. As a result, investors are able to participate in the growth potential
of virtually the entire market.

LOOKING AHEAD

After a turbulent first half of the year, the bearish sentiment that has
overshadowed the markets over the last several months seems to have peaked. The
interest rate hikes conducted by the Federal Reserve have

LETTER TO THE SHAREHOLDERS July 31, 2000, continued

slowed economic growth moderately and have alleviated fears of higher inflation.
Continued strength in corporate earnings and hopes that the Fed can once again
orchestrate a soft landing may create a positive environment for the equity
markets.

We appreciate your ongoing support of Morgan Stanley Dean Witter Total Market
Index 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 TOTAL MARKET INDEX FUND
NOTES TO FINANCIAL STATEMENTS July 31, 2000

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter Total Market Index 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 investment
objective is to provide investment results that, before expenses, correspond to
the total return of the Wilshire 5000 Equity Index (the "Index"). The Fund seeks
to achieve its objective by investing at least 80% of its total assets in stocks
included in the Index. The Fund was organized as a Massachusetts business trust
on March 11, 1999 and had no operations other than those relating to
organizational matters and the issuance of 2,500 shares of beneficial interest
by each class for $25,000 of each class to Morgan Stanley Dean Witter Advisors
Inc. (the "Investment Manager") to effect the Fund's initial capitalization. The
Fund commenced operations on September 28, 1999.

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 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; (3) when market quotations are not readily available, including
circumstances under which it is determined by 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

                                       48

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.
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. FUTURES CONTRACTS -- A futures contract is an agreement between two parties
to buy and sell financial instruments at a set price on a future date. Upon
entering into such a contract, the Fund is required to pledge to the broker
cash, U.S. Government securities or other liquid portfolio securities equal to
the minimum initial margin requirements of the applicable futures exchange.
Pursuant to the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in the value of the contract
which is known as variation margin. Such receipts or payments are recorded by
the Fund as unrealized gains or losses. Upon closing of the contract, the Fund
realizes a gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.

E. 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.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the ex-dividend 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

                                       49

NOTES TO FINANCIAL STATEMENTS July 31, 2000, continued

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.

G. OFFERING COSTS -- The Investment Manager incurred offering costs on behalf of
the Fund in the amount of approximately $159,000, which will be reimbursed by
the Fund for the full amount thereof. Such expenses were deferred and are being
amortized on the straight-line method over a period of approximately one year or
less 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
annual rate of 0.40% to the net assets of the Fund determined as of the close of
each business day.

The Investment Manager has agreed to assume all operating expenses (except for
Plan of Distribution fees) and to waive the compensation provided for in its
Investment Management Agreement to the extent that such expenses and
compensation on an annualized basis exceed 0.50% of the daily net assets of 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 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
$15,462,992 at July 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, respectively, will

                                       50

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 period ended July 31, 2000,
the distribution fee was accrued for Class A shares and Class C shares at the
annual rate of 0.25% and 1.0%, respectively.

The Distributor has informed the Fund that for the period ended July 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 $3,202, $727,244 and
$45,054, respectively and received $118,994 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 period ended July 31, 2000 aggregated
$383,073,932 and $6,323,663, respectively. Included in the aforementioned are
purchases of common stock of Morgan Stanley Dean Witter & Co., an affiliate of
the Investment Manager and Distributor, of $1,516,251.

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

5. FEDERAL INCOME TAX STATUS

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 $415,000 during fiscal 2000.

As of July 31, 2000, the Fund had temporary book/tax differences primarily
attributable to post-October losses, and the mark-to-market of open futures
contracts and permanent book/tax differences primarily attributable to a net
operating loss and nondeductible expenses. To reflect reclassifications arising
from the permanent differences, paid-in-capital was charged $393,880, net
realized loss was charged $20,743 and net investment loss was credited $414,623.

7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS

To hedge against adverse interest rate, foreign currency and market risks, the
Fund may purchase and sell interest rate, currency and index futures contracts
("futures contracts").

Futures 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 value of the underlying securities or currencies.
Risks may also arise upon entering into these contracts from the potential
inability of the counterparties to meet the terms of their contracts.

At July 31, 2000, the Fund had open futures contracts.

MORGAN STANLEY DEAN WITTER TOTAL MARKET INDEX FUND
INDEPENDENT AUDITORS' REPORT

TO THE SHAREHOLDERS AND BOARD OF TRUSTEES
OF MORGAN STANLEY DEAN WITTER TOTAL MARKET INDEX FUND:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Dean Witter Total Market Index Fund (the "Fund"), including the
portfolio of investments, as of July 31, 2000, and the related statements of
operations and changes in net assets, and financial highlights for the period
September 28, 1999 (commencement of operations) to July 31, 2000. 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.

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 at July 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 presentation. We believe that our audit
provides a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Morgan Stanley Dean
Witter Total Market Index Fund as of July 31, 2000, the results of its
operations, the changes in its net assets and the financial highlights for the
period September 28, 1999 (commencement of operations) to July 31, 2000 in
conformity with accounting principles generally accepted in the United States of
America.

MORGAN STANLEY DEAN WITTER TOTAL MARKET INDEX FUND
CHANGE IN INDEPENDENT ACCOUNTANTS

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

The report of PricewaterhouseCoopers LLP on the financial statements of the Fund
as of July 21, 1999 contained no adverse opinion or disclaimer of opinion and
was not qualified or modified as to uncertainty, audit scope or accounting
principle.

From July 21, 1999 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.

The Fund, with the approval of its Board of Trustees and its Audit Committee,
engaged Deloitte & Touche LLP as its new independent accountants for the period
ended July 31, 2000.
