MARKET CONDITIONS

The six-month period under review began on a positive note following stronger
than expected payroll gains reported in April. While that month was otherwise
uneventful in the bond market, the Federal Open Market Committee (the "Fed")
publicly laid the groundwork at its meeting for future interest-rate increases
on May 4, 2004.

The Fed went on to raise rates at its June as well as subsequent meetings,
bringing the overnight federal funds rate to 1.75 percent by the end of the
period. Despite these changes, however, continued softness in the economy pushed
yields on intermediate and longer-maturity securities lower in the third and
into the fourth quarter of 2004. The market's concerns were fueled by continued
weakness in employment growth, steady rises in oil prices and uncertainty over
the outcome of the U.S. presidential election.

Against this mixed backdrop, performance varied over the major segments of the
fixed income market. U.S. Treasury securities lagged other parts of the market
thanks to their high sensitivity to fluctuating interest rates and their
relatively low yields. Mortgage-backed securities (MBS) lagged as interest rates
declined during the period. Corporate bonds turned in the best performance of
any major market sector, led by lower-quality securities. Paper, energy and
industrials were the best-performing industries within the corporate bond
market, reflecting investors' general interest in economically sensitive
industries.

PERFORMANCE ANALYSIS

Morgan Stanley Limited Duration Fund underperformed both the Lehman Brothers 1-5
Year U.S. Credit Index and the Lipper Short Investment Grade Bond Funds Index
for the six months ended October 31, 2004. While rates were volatile during the
period, they largely ended the six-month period lower than where they began. As
a result, two of the Fund's key strategies that tend to outperform in
rising-rate environments exerted a drag on its performance.

The first of these strategies was to keep the Fund's duration*, or interest-rate
sensitivity, below that of its benchmark. This approach was based on the fact
that interest rates at the start of the period were at historic lows and thus
had more likelihood of rising than falling. While yields did move higher at
points during the period, the net decline over the course of the period caused
the strategy to detract from performance. Performance was also hampered by the
Fund's emphasis on higher-coupon MBS, which tend to underperform in periods when
overall yields decline.

Several of the Fund's other strategies were more beneficial to its returns. The
Fund's below-benchmark position in agency securities helped limit the adverse
effects of the ongoing fallout from the accounting scandal at the Federal
National Mortgage Association (FNMA). The Fund also gained from its emphasis on
outperforming industries within the corporate sector; its holdings of industrial
and energy bonds were particularly helpful.

* A MEASURE OF THE SENSITIVITY OF A BOND'S PRICE TO CHANGES IN INTEREST RATES,
EXPRESSED IN YEARS. EACH YEAR OF DURATION REPRESENTS AN EXPECTED 1 PERCENT
CHANGE IN THE PRICE OF A BOND FOR EVERY 1 PERCENT CHANGE IN INTEREST RATES. THE
LONGER A BOND'S DURATION, THE GREATER THE EFFECT OF INTEREST-RATE MOVEMENTS ON
ITS PRICE. TYPICALLY, FUNDS WITH SHORTER DURATIONS PERFORM BETTER IN
RISING-INTEREST-RATE ENVIRONMENTS, WHILE FUNDS WITH LONGER DURATIONS PERFORM
BETTER WHEN RATES DECLINE.

THERE IS NO GUARANTEE THAT ANY SECURITIES MENTIONED WILL CONTINUE TO PERFORM
WELL OR BE HELD BY THE FUND IN THE FUTURE.

EXPENSE EXAMPLE

As a shareholder of the Fund, you incur ongoing costs, including management
fees; and other Fund expenses. This example is intended to help you understand
your ongoing costs (in dollars) of investing in the Fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period 05/01/04 - 10/31/04.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table below provides information about hypothetical
expenses based on the Fund's actual expense ratio and an assumed rate of return
of 5% per year before expenses, which is not the Fund's actual return. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period. You may use this
information to compare the ongoing cost of investing in the Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only. Therefore, the second line of the table is useful in
comparing ongoing costs, and will not help you determine the relative total cost
of owning different funds that have transactional costs, such as sales charges
(loads), and redemption fees, or exchange fees.

MORGAN STANLEY LIMITED DURATION FUND

NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2004 (UNAUDITED)

1. ORGANIZATION AND ACCOUNTING POLICIES
Morgan Stanley Limited Duration Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's investment objective is to provide a
high level of current income consistent with the preservation of capital. The
Fund was organized as a Massachusetts business trust on October 22, 1993 and
commenced operations on January 10, 1994.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS -- (1) certain portfolio securities may be valued by
an outside pricing service approved by the Fund's Trustees (2) portfolio
securities for which over-the-counter market quotations are readily available
are valued at the mean between the last reported bid and asked price; (3)
futures are valued at the latest price published by the commodities exchange on
which they trade; (4) when market quotations are not readily available or Morgan
Stanley Investment Advisors Inc. (the "Investment Manager") determines that the
market quotations 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 Fund's
Trustees; 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.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. REPURCHASE AGREEMENTS -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Manager, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, U.S. Treasury or federal agency obligations. The Fund may also invest
directly with institutions in repurchase agreements. The Fund's custodian
receives the collateral, which is marked-to-market daily to determine that the
value of the collateral does not decrease below the repurchase price plus
accrued interest.

D. FUTURES CONTRACTS -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices 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

                                       23
<Page>

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. Such receipts or payments known as
variation margin are recorded by the Fund as unrealized gains and 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 POLICY -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

G. USE OF ESTIMATES -- 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.

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 as of the close
of each business day: 0.60% to the portion of the daily net assets not exceeding
$1 billion; 0.55% to the portion of daily net assets exceeding $1 billion but
not exceeding $2 billion and 0.50% to the portion of daily net assets exceeding
$2 billion.

3. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
The cost of purchases and proceeds from sales/prepayments of portfolio
securities, excluding short-term investments, for the six months ended October
31, 2004 were $238,234,393, and $290,629,735, respectively. Included in the
aforementioned are purchases and sales/prepayments of U.S. Government securities
of $193,749,857 and $225,732,453, respectively.

Morgan Stanley Trust, an affiliate of the Investment Manager, is the Fund's
transfer agent. At October 31, 2004, the Fund had transfer agent fees and
expenses payable of approximately $7,800.

Effective April 1, 2004, the Fund began an unfunded Deferred Compensation Plan
(the "Compensation Plan") which allows each independent Trustee to defer payment
of all, or a portion, of the fees he receives for serving on the Board of
Trustees. Each eligible Trustee generally may elect to have the deferred amounts
credited with a return equal to the total return on one or more of the Morgan
Stanley funds that are offered as investment options under the Compensation
Plan. Appreciation/depreciation

                                       24
<Page>

and distributions received from these investments are recorded with an
offsetting increase/decrease in the deferred compensation obligation and do not
affect the net asset value of the Fund.

4. SHARES OF BENEFICIAL INTEREST
Transactions in shares of beneficial interest were as follows:

                            ==============    ==============    ==============    ==============
</Table>

5. FEDERAL INCOME TAX STATUS
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 tax purposes are reported as distributions of paid-in-capital.

*As of April 30, 2004, the Fund had a net capital loss carryforward of
$7,680,764 of which $151,743 will expire on April 30, 2005, $1,656,930 will
expire on April 30, 2006, $20,504 will expire on April 30, 2007, $51,242 will
expire on April 30, 2008, $2,035,052 will expire on April 30, 2009, $1,582,163
will expire on April 30, 2011 and $2,183,130 will expire on April 30, 2012 to
offset future capital gains to the extent provided by regulations.

The Fund obtained a net capital loss carryforward which currently amounts to
$2,030,677 from prior year fund acquisitions. Utilization of this carryforward
is subject to limitations imposed by the Internal Revenue Code and Treasury
Regulations, reducing the total carryforward available.

As of April 30, 2004, the Fund had temporary book/tax differences primarily
attributable to post-October losses (capital losses incurred after October 31
within the taxable year which are deemed to

                                       25
<Page>

arise on the first business day of the Fund's next taxable year, )and book
amortization of premiums on debt securities.

6. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
To hedge against adverse interest rate and market risks on portfolio positions
or anticipated positions in U.S. Government securities, the Fund may enter into
interest rate futures contracts ("futures contracts").

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement and Assets and Liabilities. The Fund bears the risk
of an unfavorable change in the value of the underlying securities. Risk may
also arise upon entering into contracts from the potential inability of the
counterparties to meet the terms of their contracts.

7. EXPENSE OFFSET
The expense offset represents a reduction of the custodians fees for earnings on
cash balances maintained by the Fund.

8. LEGAL MATTERS
The Investment Manager, certain affiliates of the Investment Manager, certain
officers of such affiliates and certain investment companies advised by the
Investment Manager or its affiliates, including the Fund, are named as
defendants in a number of similar class action complaints which were recently
consolidated. This consolidated action also names as defendants certain
individual Trustees and Directors of the Morgan Stanley funds. The consolidated
amended complaint generally alleges that defendants, including the Fund,
violated their statutory disclosure obligations and fiduciary duties by failing
properly to disclose (i) that the Investment Manager and certain affiliates of
the Investment Manager allegedly offered economic incentives to brokers and
others to recommend the funds advised by the Investment Manager or its
affiliates to investors rather than funds managed by other companies, and (ii)
that the funds advised by the Investment Manager or its affiliates, including
the Fund, allegedly paid excessive commissions to brokers in return for their
efforts to recommend these funds to investors. The complaint seeks, among other
things, unspecified compensatory damages, rescissionary damages, fees and costs.
The defendants have moved to dismiss the action and intend to otherwise
vigorously defend it. While the Fund believes that it has meritorious defenses,
the ultimate outcome of this matter is not presently determinable at this early
stage of the litigation, and no provision has been made in the Fund's financial
statements for the effect, if any, of this matter.
