Performance Summary for standardized performance and benchmark information.

MARKET CONDITIONS

The Federal Open Market Committee (the "Fed") raised the federal funds target
rate by 25 basis points at both the May and June meetings, but then chose to
pause at the following three meetings. Comments made by Fed members after their
May and June meetings indicated that they will rely heavily on economic data in
making future decisions concerning the direction of interest rates. In fact,
based on these comments it appears that the Fed will be driven by the weight of
the economic data more so now than perhaps at anytime over the past few years.

At first glance, the third quarter gross domestic product (GDP) report was
disappointing, with the real economy expanding at a 1.6 percent annualized rate
during the period -- its weakest showing in three years. A further analysis,
however, suggests a more favorable view of the economy.

Most observers expected that housing would be a drag on GDP, and it certainly
was to the tune of approximately one full percentage point during the period.
However, this is far from a crushing blow to an economy that had been growing at
or above its long-term potential growth rate for the past few years. There is
also evidence that home sellers are responding to the housing market correction
by either withdrawing inventory from the market or by adjusting asking
prices -- both of which may tend to limit the severity and longevity of the
housing correction. Moreover, the so-called negative wealth effect caused by
lower home prices is open to debate. Empirical evidence shows that the assumed
relationships between mortgage equity withdrawals and consumer spending are
unstable in both the short run and the long run.

A further analysis of the third quarter GDP report also revealed strong gains in
both non-residential real restate and in real equipment spending. We are not
suggesting that investors ignore the relatively weak headline GDP number;
instead, we are suggesting that there is more to the report than meets the eye,
especially when evaluated within the context of other economic barometers.

Where does all of this leave the Fed? With inflation above 2 percent and
expectations for strong growth, we believe there is little support in any of the
recent data to justify a more accommodative monetary policy. If anything, there
is cause for concern on the inflation front, especially with tight labor
markets. Accordingly, a higher federal funds rate may well be necessary to
control the level of inflation and, accordingly, nominal economic growth rates.

Within the government sector, U.S. Treasuries underperformed over the six-month
period because of

 2


their high sensitivity to fluctuating interest rates and their relatively low
yields. Yield spreads (a measure of market risk) of agency debentures and
mortgages remained tight relative to Treasuries. As is typical during periods of
declining interest rates, prepayment speeds on mortgages rose, causing
lower-coupon mortgages to outperform.

Within the investment-grade portion of the corporate sector, lower-rated issues
(BBB- and A-rated) outpaced higher-rated issues (AA-rated and above).
Industrials posted the highest returns, followed by utilities and financials.
Overall for the period, longer dated corporate issues underperformed
shorter-dated issues.

PERFORMANCE ANALYSIS

Morgan Stanley Limited Duration Fund underperformed the Lehman Brothers U.S.
Credit Index (1-5 Year) and the Lipper Short Investment Grade Bond Funds Index
for the six months ended October 31, 2006, assuming no deduction of applicable
sales charges.

During the period, we kept the Fund's overall duration* modestly below that of
the relevant indices. This posture was beneficial as interest rates rose across
the market, especially in the short- and intermediate-portions of the yield
curve.

The portfolio had a small exposure to higher-coupon mortgage backed securities
which benefited performance. Additionally, the portfolio had significant
exposure to adjustable rate mortgages which enhanced performance.

Within the credit section of the Portfolio, we employed a defensive strategy
with a focus on higher-quality securities, which detracted from relative
performance. However, strong security selection contributed positively to
performance for the period.

There is no guarantee that any sectors mentioned will continue to perform as
discussed herein or that securities in such sectors will be held by the Fund in
the future.

*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.

INVESTMENT STRATEGY

The Fund will normally invest at least 65 percent of its assets in securities
issued or guaranteed as to principal and interest by the U.S. Government, its
agencies or instrumentalities (including zero coupon securities), investment
grade mortgage-backed securities, including collateralized mortgage obligations,
and investment grade corporate and other types of bonds. In selecting portfolio
investments to purchase or sell, the "Investment Adviser," Morgan Stanley
Investment Advisors Inc., considers both domestic and international economic
developments, interest rate levels, the steepness of the yield curve and other
factors, and seeks to maintain an overall average duration for the Fund's
portfolio of three years or less.

Performance data quoted represents past performance, which is no guarantee of
future results and current performance may be lower or higher than the figures
shown. For most recent month-end performance figures, please visit
www.morganstanley.com or speak with your Financial Advisor. Investment returns
and principal value will fluctuate and fund shares, when redeemed, may be worth
more or less than their original cost. The table does not reflect the deduction
of taxes that a shareholder would pay on fund distributions or the redemption of
fund shares.

(1)  The Lehman Brothers U.S. Credit Index (1-5 Year) includes U.S. corporate
     and specified foreign debentures and secured notes with maturities of one
     to five years. Indexes are unmanaged and their returns do not include any
     sales charges or fees. Such costs would lower performance. It is not
     possible to invest directly in an index.

(2)  The Lipper Short Investment Grade Bond Funds Index is an equally weighted
     performance index of the largest qualifying funds (based on net assets) in
     the Lipper Short Investment Grade Bond Funds classification. The Index,
     which is adjusted for capital gains distributions and income dividends, is
     unmanaged and should not be considered an investment. There are currently
     30 funds represented in this Index.

(3)  Figure shown assumes reinvestment of all distributions. There are no sales
     charges.

EXPENSE EXAMPLE


As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees; and (2) ongoing costs, including advisory 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 05/01/06 - 10/31/06.

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), redemption fees or exchange fees.

</Table>

- ------------------

 *  Expenses are equal to the Fund's annualized expense ratio of 0.80%
    multiplied by the average account value over the period, multiplied by
    184/365 (to reflect the one-half year period). If the Fund had borne all of
    its expenses waived by the Investment Adviser and Administrator, the
    annualized expense ratios for the one-half period would have been 0.87%.

Morgan Stanley Limited Duration Fund
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (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 Fund will assess a 2% redemption fee, which is paid directly to the Fund,
for shares redeemed within seven days of purchase, subject to certain
exceptions. The redemption fee is designed to protect the Fund and its remaining
shareholders from the effects of short-term trading.

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 including
circumstances under which Morgan Stanley Investment Advisors Inc. (the
"Investment Adviser") 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; (5) listed options are valued at the
latest sale price on the exchange on which they are listed unless no sales of
such options have taken place that day, in which case they are valued at the
mean between their latest bid and asked price; and (6) 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 Adviser, 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

20


Morgan Stanley Limited Duration Fund
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (UNAUDITED) continued

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 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. Options -- When the Fund writes a call option, an amount equal to the premium
received is included in the Fund's Statement of Assets and Liabilities as a
liability which is subsequently marked-to-market to reflect the current market
value of the option written. If a written option either expires or the Fund
enters into a closing purchase transaction, the Fund realizes a gain or loss
without regard to any unrealized gain or loss on the underlying security or
currency and the liability related to such option is extinguished. If a written
call option is exercised, the Fund realizes a gain or loss from the sale of the
underlying security or currency and the proceeds from such sale are increased by
the premium originally received.

When the Fund purchases a call or put option, the premium paid is recorded as an
investment and is subsequently marked-to-market to reflect the current market
value. If a purchased option expires, the Fund will realize a loss to the extent
of the premium paid. If the Fund enters into a closing sale transaction, a gain
or loss is realized for the difference between the proceeds from the sale and
the cost of the option. If a put option is exercised, the cost of the security
or currency sold upon exercise will be increased by the premium originally paid.
If a call option is exercised, the cost of the security purchased upon exercise
will be increased by the premium originally paid.

F. 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.

G. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

                                                                              21


Morgan Stanley Limited Duration Fund
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (UNAUDITED) continued

H. 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 Advisory/Administration Agreements

Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment
Adviser, the Fund pays an advisory 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: 0.52% of the portion of the daily net assets
not exceeding $1 billion; 0.47% to the portion of the daily net assets exceeding
$1 billion but not exceeding $2 billion and 0.42% of the portion of the daily
net assets in excess of $2 billion.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund
pays an administration fee, accrued daily and payable monthly, by applying the
annual rate of 0.08% to the Fund's daily net assets.

Effective November 18, 2005, the Investment Adviser has agreed to cap the Fund's
operating expenses for one year by assuming the Fund's "other expenses" and/or
waiving the Fund's advisory fees, and the Administrator has agreed to waive the
Fund's administrative fees, to the extent such operating expenses on an
annualized basis exceed 0.80% of the average daily net assets of the Fund.

3. Security Transactions and Transactions with Affiliates

The cost of purchases and proceeds from sales/maturities/prepayments of
portfolio securities, excluding short-term investments, for the six months ended
October 31, 2006 were $40,956,339, and $55,278,858, respectively. Included in
the aforementioned are purchases and sales/prepayments of U.S. Government
securities of $7,481,640 and $12,744,948, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser and Administration,
is the Fund's transfer agent.

The Fund has 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 or she 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 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.

</Table>

5. Expense Offset

The expense offset represents a reduction of the fees and expenses for interest
earned on cash balances maintained by the Fund with the transfer agent.

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").

For hedging and investment purposes, the Fund may also engage in transactions in
listed and over-the-counter options.

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of 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 counterparts
to meet the terms of their contracts.

7. 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.

                                                                              23


Morgan Stanley Limited Duration Fund
NOTES TO FINANCIAL STATEMENTS - OCTOBER 31, 2006 (UNAUDITED) continued

As of April 30, 2006, the Fund had a net capital loss carryforward of
$21,831,288 of which $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, $2,183,130 will expire on April 30, 2012, $11,744,997
will expire on April 30, 2013 and $4,214,200 will expire on April 30, 2014 to
offset future capital gains to the extent provided by regulations.

As of April 30, 2006, 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 arise on the first business day of
the Fund's next taxable year), and book amortization on debt securities.

8. New Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes -- an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006. The Fund will
adopt FIN 48 for the fiscal year ending 2008 and the impact to the Fund's
financial statements, if any, is currently being assessed.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.
