INVESTMENT MANAGEMENT

Welcome, Shareholder:

In this report, you’ll learn about how your investment in Morgan Stanley Insured Municipal Income Trust performed during the annual period. We will provide an overview of the market conditions, and discuss some of the factors that affected performance during the reporting period. In addition, this report includes the Trust’s financial statements and a list of Trust investments.

Market forecasts provided in this report may not necessarily come to pass. There is no assurance that the Trust will achieve its investment objective. The Trust is subject to market risk, which is the possibility that market values of securities owned by the Trust will decline and, therefore, the value of the Trust’s shares may be less than what you paid for them. Accordingly, you can lose money investing in this Trust.

Income earned by certain securities in the portfolio may be subject to the federal alternative minimum tax (AMT).

Fund Report

For the year ended October 31, 2008

Market Conditions

The financial markets were highly volatile throughout the reporting period as disrupted credit markets, recession fears, the declining housing market, and ongoing losses in the financial sector led to increasing investor anxiety. The third quarter of 2008, in particular, will go down as a defining moment in financial history, a period in which the industry’s landscape changed in ways most would have never imagined.

As the quarter began, Federal National Mortgage Association (“Fannie Mae”) and Federal Home Loan Mortgage Corporation (“Freddie Mac”), the two bedrock government-sponsored entities that own or guarantee about half of the nation’s outstanding mortgage debt, were facing financial disintegration as the value of the agencies’ assets had severely eroded. At the same time, economic data was signaling slowing growth while rising food and energy prices were fueling inflation, heightening investor anxiety. In early September, deteriorating market conditions caused the U.S. Treasury to rescue both Fannie Mae and Freddie Mac. Shortly thereafter, these same conditions led Lehman Brothers to file for bankruptcy protection. Investor confidence plummeted, initiating a downward spiral in the market that accelerated at an alarming pace. In the weeks that followed, several other large financial institutions were forced into mergers, rescued by the government, or failed altogether.

Credit markets became nearly frozen as liquidity dried up. Overnight and short-term credit markets convulsed as banks stopped lending to both companies and each other, causing short-term borrowing costs to soar. As fear gripped the market, credit spreads dramatically widened as investors demanded substantial compensation for assuming any degree of risk. In response, government officials took various steps including a $700 billion plan to fortify the precarious financial system.

Overall, the consolidation in the banking and brokerage industry has altered the flow of capital and resulted in a general lack of liquidity in the municipal market. The biggest issue facing the municipal market as of the end of the period is a general lack of trading as new issue offerings have been pulled and/or downsized. And, while liquidity improved in October, demand remains well below historic levels. As a result, yields on even the highest quality, most liquid municipal securities are at historic highs, with yields on 30-year high-grade municipal issues at levels well above that of comparable Treasuries.

Rising unemployment has resulted in declining tax receipts, which directly impacts the bottom line of state budgets. In fact, state budget gaps have widened substantially, with 39 states projected to face fiscal distress in 2009 and 2010.

Performance Analysis

For the 12-month period ended October 31, 2008, the net asset value (NAV) of Morgan Stanley Insured Municipal Income Trust (IIM) decreased from $15.32 to $12.76 per share. Based on this change plus reinvestment of tax-free dividends totaling $0.6825 per share and a long-term capital gain distribution of $0.017749 per share, the Trust’s total NAV return was –12.13 percent. IIM’s value on the New York Stock Exchange (NYSE) moved from $13.81 to $10.76 per share during the same period. Based on this change plus reinvestment of dividends and

distributions, the Trust’s total market return was –17.80 percent. IIM’s NYSE market price was at a 15.67 percent discount to its NAV. During the fiscal period, the Trust purchased and retired 201,484 shares of common stock at a weighted average market discount of 10.41 percent. Past performance is no guarantee of future results.

The October dividend was decreased to $0.05 per share. The dividend reflects the current level of the Trust’s net investment income. IIM’s level of undistributed net investment income was $0.060 per share on October 31, 2008 versus $0.056 per share 12 months earlier.¹

Over the course of the reporting period, we maintained an overweight to the hospital/life care and tobacco sectors, which detracted from relative performance as spreads in these sectors widened, pushing prices lower. Conversely, an overweight to the public utility sector benefited performance as the flight to quality that took place during the period helped to boost the performance of this infrastructure sector.

In the first half of the period, the Trust maintained a lower interest-rate sensitivity (as measured by duration*), which benefited relative performance as yield rose. During the second half of the period, we increased the duration to a neutral stance in order to better position the Trust to benefit from a potential retracement in yields in the future.

The Trust’s procedure for reinvesting all dividends and distributions in common shares is through purchases in the open market. This method helps support the market value of the Trust’s shares. In addition, we would like to remind you that the Trustees have approved a share repurchase program whereby the Trust may, when appropriate, purchase shares in the open market or in privately negotiated transactions at a price not above market value or net asset value, whichever is lower at the time of purchase. The Trust may also utilize procedures to reduce or eliminate the amount of Auction Rate Preferred Shares (ARPS) outstanding, including their purchase in the open market or in privately negotiated transactions.

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. Investment return, net asset value and common share market price will fluctuate and Trust shares, when sold, may be worth more or less than their original cost.

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 Trust in the future.

¹ Income earned by certain securities in the portfolio may be subject to the federal alternative minimum tax (AMT).

* 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, trusts with shorter durations perform better in rising-interest-rate environments, while trusts with longer durations perform better when rates decline. Duration calculations are adjusted for leverage.

Investment Advisory Agreement Approval

Nature, Extent and Quality of Services

The Board reviewed and considered the nature and extent of the investment advisory services provided by the Investment Adviser (as defined herein) under the advisory agreement, including portfolio management, investment research and fixed income securities trading. The Board also reviewed and considered the nature and extent of the non-advisory, administrative services provided by the Trust’s Administrator (as defined herein) under the administration agreement, including accounting, clerical, bookkeeping, compliance, business management and planning, and the provision of supplies, office space and utilities at the Investment Adviser’s expense. (The Investment Adviser and the Administrator together are referred to as the “Adviser” and the advisory and administration agreements together are referred to as the “Management Agreement.”) The Board also compared the nature of the services provided by the Adviser with similar services provided by non-affiliated advisers as reported to the Board by Lipper Inc. (“Lipper”).

The Board reviewed and considered the qualifications of the portfolio managers, the senior administrative managers and other key personnel of the Adviser who provide the administrative and advisory services to the Trust. The Board determined that the Adviser’s portfolio managers and key personnel are well qualified by education and/or training and experience to perform the services in an efficient and professional manner. The Board concluded that the nature and extent of the advisory and administrative services provided were necessary and appropriate for the conduct of the business and investment activities of the Trust. The Board also concluded that the overall quality of the advisory and administrative services was satisfactory.

Performance Relative to Comparable Funds Managed by Other Advisers

On a regular basis, the Board reviews the performance of all funds in the Morgan Stanley Fund Complex, including the Trust, compared to their peers, paying specific attention to the underperforming funds. In addition, the Board specifically reviewed the Trust’s performance for the one-, three- and five-year periods ended December 31, 2007, as shown in a report provided by Lipper (the “Lipper Report”), compared to the performance of comparable funds selected by Lipper (the “performance peer group”). The Board also discussed with the Adviser the performance goals and the actual results achieved in managing the Trust. The Board concluded that the Trust’s performance was competitive with that of its performance peer group.

Fees Relative to Other Proprietary Funds Managed by the Adviser with Comparable Investment Strategies

The Board reviewed the advisory and administrative fee (together, the “management fee”) rate paid by the Trust under the Management Agreement. The Board noted that the management fee rate was comparable to

the management fee rates charged by the Adviser to other proprietary funds it manages with investment strategies comparable to those of the Trust.

Fees and Expenses Relative to Comparable Funds Managed by Other Advisers

The Board reviewed the management fee rate and total expense ratio of the Trust as compared to the average management fee rate and average total expense ratio for funds, selected by Lipper (the “expense peer group”), managed by other advisers with investment strategies comparable to those of the Trust, as shown in the Lipper Report. The Board concluded that the Trust’s management fee rate and total expense ratio were competitive with those of its expense peer group.

Breakpoints and Economies of Scale

The Board reviewed the structure of the Trust’s management fee schedule under the Management Agreement and noted that it does not include any breakpoints. The Board considered that the Trust is a closed-end fund and, therefore, that the Trust’s assets are not likely to grow with new sales or grow significantly as a result of capital appreciation. The Board concluded that economies of scale for the Trust were not a factor that needed to be considered at the present time.

Profitability of the Adviser and Affiliates

The Board considered information concerning the costs incurred and profits realized by the Adviser and affiliates during the last year from their relationship with the Trust and during the last two years from their relationship with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost allocation methodology used to determine the profitability of the Adviser and affiliates. Based on its review of the information it received, the Board concluded that the profits earned by the Adviser and affiliates were not excessive in light of the advisory, administrative and other services provided to the Trust.

Fall-Out Benefits

The Board considered so-called “fall-out benefits” derived by the Adviser and affiliates from their relationship with the Trust and the Morgan Stanley Fund Complex, such as “float” benefits derived from handling of checks for purchases and sales of Trust shares, through a broker-dealer affiliate of the Adviser. The Board also considered that, from time to time, the Adviser may, directly or indirectly, effect trades on behalf of certain Morgan Stanley Funds through various electronic communications networks or other alternative trading systems in which the Adviser’s affiliates have ownership interests and/or board seats. The Board concluded that the fall-out benefits were relatively small.

Soft Dollar Benefits

The Board considered whether the Adviser realizes any benefits from commissions paid to brokers who execute securities transactions for the Trust (“soft dollars”). The Board noted that the Trust invests only in fixed income securities, which do not generate soft dollars.

Adviser Financially Sound and Financially Capable of Meeting the Trust’s Needs

The Board considered whether the Adviser is financially sound and has the resources necessary to perform its obligations under the Management Agreement. The Board concluded that the Adviser has the financial resources necessary to fulfill its obligations under the Management Agreement.

Historical Relationship Between the Trust and the Adviser

The Board also reviewed and considered the historical relationship between the Trust and the Adviser, including the organizational structure of the Adviser, the policies and procedures formulated and adopted by the Adviser for managing the Trust’s operations and the Board’s confidence in the competence and integrity of the senior managers and key personnel of the Adviser. The Board concluded that it is beneficial for the Trust to continue its relationship with the Adviser.

Other Factors and Current Trends

The Board considered the controls and procedures adopted and implemented by the Adviser and monitored by the Trust’s Chief Compliance Officer and concluded that the conduct of business by the Adviser indicates a good faith effort on its part to adhere to high ethical standards in the conduct of the Trust’s business.

General Conclusion

After considering and weighing all of the above factors, the Board concluded that it would be in the best interest of the Trust and its shareholders to approve renewal of the Management Agreement for another year.

Notes to Financial Statements - October 31, 2008

1. Organization and Accounting Policies

Morgan Stanley Insured Municipal Income Trust (the “Trust”) is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The Trust’s investment objective is to provide current income which is exempt from federal income taxes. The Trust was organized as a Massachusetts business trust on March 12, 1992 and commenced operations on February 26, 1993.

The following is a summary of significant accounting policies:

A. Valuation of Investments — (1) portfolio securities are valued by an outside independent pricing service approved by the Trustees. The pricing service uses both a computerized grid matrix of tax-exempt securities and evaluations by its staff, in each case based on information concerning market transactions and quotations from dealers which reflect the mean between the last reported bid and asked price. The portfolio securities are thus valued by reference to a combination of transactions and quotations for the same or other securities believed to be comparable in quality, coupon, maturity, type of issue, call provisions, trading characteristics and other features deemed to be relevant. The Trustees believe that timely and reliable market quotations are generally not readily available for purposes of valuing tax-exempt securities and that the valuations supplied by the pricing service are more likely to approximate the fair value of such securities; (2) futures are valued at the latest sale price on the commodities exchange on which they trade unless it is determined that such price does not reflect their market value, in which case they will be valued at their fair value as determined in good faith under procedures established by and under the supervision of the Trustees; (3) interest rate swaps are marked-to-market daily based upon quotations from market makers; (4) investments in open-end mutual funds, including the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the close of each business day; 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 and are included in interest income. Interest income is accrued daily.

C. 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 Trust 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.

Notes to Financial Statements - October 31, 2008 continued

Pursuant to the contract, the Trust 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 Trust as unrealized gains and losses. Upon closing of the contract, the Trust 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.

D. Floating Rate Note Obligations Related to Securities Held — The Trust enters into transactions in which it transfers to Dealer Trusts (“Dealer Trusts”), fixed rate bonds in exchange for cash and residual interests in the Dealer Trusts’ assets and cash flows, which are in the form of inverse floating rate investments. The Dealer Trusts fund the purchases of the fixed rate bonds by issuing floating rate notes to third parties and allowing the Trust to retain residual interest in the bonds. The Trust enters into shortfall agreements with the Dealer Trusts which commit the Trust to pay the Dealer Trusts, in certain circumstances, the difference between the liquidation value of the fixed rate bonds held by the Dealer Trusts and the liquidation value of the floating rate notes held by third parties, as well as any shortfalls in interest cash flows. The residual interests held by the Trust (inverse floating rate investments) include the right of the Trust (1) to cause the holders of the floating rate notes to tender their notes at par at the next interest rate reset date, and (2) to transfer the municipal bond from the Dealer Trusts to the Trust, thereby collapsing the Dealer Trusts. The Trust accounts for the transfer of bonds to the Dealer Trusts as secured borrowings, with the securities transferred remaining in the Trust’s investment assets, and the related floating rate notes reflected as Trust liabilities under the caption “floating rate note obligations” on the Statement of Assets and Liabilities. The Trust records the interest income from the fixed rate bonds under the caption “interest” and records the expenses related to floating rate obligations and any administrative expenses of the Dealer Trusts under the caption “interest and residual trust expenses” in the Trust’s Statement of Operations. The floating rate notes issued by the Dealer Trusts have interest rates that reset weekly and the floating rate note holders have the option to tender their notes to the Dealer Trusts for redemption at par at each reset date. At October 31, 2008, the Trust has investments with a value of $79,449,141 that are held by the Dealer Trusts and serve as collateral for the $54,645,000 in the floating rate note obligations outstanding at that date. The range of contractual maturities of the floating rate note obligations and interest rates in effect at October 31, 2008, are presented in the Portfolio of Investments.

E. Interest Rate Swaps — Interest rate swaps involve the exchange of commitments to pay and receive interest based on a notional principal amount. Net periodic interest payments to be received or paid are accrued daily and are recorded as realized gains or losses in the Statement of Operations. The Trust may pay or receive cash to collateralize interest rate swap contracts. This cash collateral is recorded as assets/liabilities on the Trust’s books. Any cash received may be invested in Morgan Stanley Institutional Liquidity Funds.

Morgan Stanley Insured Municipal Income Trust

Notes to Financial Statements - October 31, 2008 continued

F. Federal Income Tax Policy — It is the Trust’s policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable and nontaxable income to its shareholders. Therefore, no provision for federal income tax is required. The Trust files tax returns with the U.S. Internal Revenue Service, New York State and New York City. The Trust adopted the provisions of the Financial Accounting Standards Board (“FASB”) Interpretation No. 48 (“FIN 48”) Accounting for Uncertainty in Income Taxes on April 29, 2008. FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The implementation of FIN 48 did not result in any unrecognized tax benefits in the accompanying financial statements. If applicable, the Trust recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in other expenses in the Statement of Operations. Each of the tax years in the four year period ended October 31, 2008, remains subject to examination by taxing authorities.

The Trust purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the Internal Revenue Service (“IRS”) will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable.

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

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 Advisors Inc. (the “Investment Adviser”), the Trust pays the Investment Adviser an advisory fee, calculated weekly and payable monthly, by applying the annual rate of 0.27% to the Trust’s average weekly net assets including current preferred shares and floating rate note obligations of $46,150,000 entered into during the year ended October 31, 2008 to retire outstanding preferred shares of the Trust.

Pursuant to an Administration Agreement with Morgan Stanley Services Company Inc. (the “Administrator”), an affiliate of the Investment Adviser, the Trust pays an administration fee, calculated weekly and payable monthly, by applying the annual rate of 0.08% to the Trust’s average weekly net assets including current preferred shares and floating rate note obligations of $46,150,000 entered into during the year ended October 31, 2008 to retire outstanding preferred shares of the Trust.

Morgan Stanley Insured Municipal Income Trust

Notes to Financial Statements - October 31, 2008 continued

Under an agreement between the Administrator and State Street Bank and Trust Company (“State Street”), State Street provides certain administrative services to the Trust. For such services, the Administrator pays State Street a portion of the fee the Administrator receives from the Trust.

3. Security Transactions and Transactions with Affiliates

The Trust invests in Morgan Stanley Institutional Liquidity Funds-Tax-Exempt Portfolio – Institutional Class, an open-end management investment company managed by an affiliate of the Investment Adviser. Investment advisory fees paid by the Trust are reduced by an amount equal to the advisory and administrative service fees paid by Morgan Stanley Institutional Liquidity Funds-Tax-Exempt Portfolio – Institutional Class with respect to assets invested by the Trust in Morgan Stanley Institutional Liquidity Funds-Tax-Exempt Portfolio – Institutional Class. For the year ended October 31, 2008, advisory fees paid were reduced by $18,622 relating to the Trust’s investment in Morgan Stanley Institutional Liquidity Funds-Tax-Exempt Portfolio – Institutional Class. Income distributions earned by the Trust are recorded as dividends from affiliate in the Statement of Operations and totaled $370,750 for the year ended October 31, 2008. During the year ended October 31, 2008, cost of purchases and sales of investments in Morgan Stanley Institutional Liquidity Funds-Tax-Exempt Portfolio – Institutional Class aggregated $130,492,057 and $129,042,374, respectively.

The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended October 31, 2008, aggregated $55,931,697 and $83,709,420, respectively.

The Trust has an unfunded noncontributory defined benefit pension plan covering certain independent Trustees of the Trust who will have served as independent Trustees for at least five years at the time of retirement. Benefits under this plan are based on factors which include years of service and compensation. The Trustees voted to close the plan to new participants and eliminate the future benefits growth due to increases to compensation after July 31, 2003. Aggregate pension costs for the year ended October 31, 2008, included in Trustees’ fees and expenses in the Statement of Operations amounted to $4,630. At October 31, 2008, the Trust had an accrued pension liability of $52,548 which is included in accrued expenses in the Statement of Assets and Liabilities.

The Trust 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 Trust.

4. Preferred Shares of Beneficial Interest

The Trust is authorized to issue up to 1,000,000 non-participating preferred shares of beneficial interest having a par value of $.01 per share, in one or more series, with rights as determined by the Trustees, without approval of the common shareholders. The Trust has issued Series 1 through 5 Auction Rate Preferred Shares (“preferred shares”) which have a liquidation value of $50,000 per share plus the redemption premium, if any, plus accumulated but unpaid dividends, whether or not declared, thereon to the date of distribution. The Trust may redeem such shares, in whole or in part, at the original purchase price of $50,000 per share plus accumulated but unpaid dividends, whether or not declared, thereon to the date of redemption.

Dividends, which are cumulative, are reset through auction procedures.


		AMOUNT						RANGE OF
SERIES	SHARES+	IN THOUSANDS+		RATE+			RESET DATE	DIVIDEND RATES++
1	281	$	14,050		3.31	%	11/03/08	2.48% – 11.73%

+		As of October 31, 2008.
++		For the year ended October 31, 2008.

Subsequent to October 31, 2008 and up through December 5, 2008, the Trust paid dividends to Series 1 through 5 at rates ranging from 1.57% to 3.31%, in the aggregate amount of $225,145.

The Trust is subject to certain restrictions relating to the preferred shares. Failure to comply with these restrictions could preclude the Trust from declaring any distributions to common shareholders or purchasing common shares and/or could trigger the mandatory redemption of preferred shares at liquidation value.

The preferred shares, which are entitled to one vote per share, generally vote with the common shares but vote separately as a class to elect two Trustees and on any matters affecting the rights of the preferred shares.

The Trust entered into additional floating rate note obligations as an alternative form of leverage in order to redeem and retire a portion of its preferred shares. For the year ended October 31, 2008, transactions in preferred shares were as follows:


	SHARES			VALUE
Outstanding at October 31, 2007		3,100		$	155,000,000
Shares retired		(923	)		(46,150,000	)

+++		The Trustees have voted to retire the shares purchased.

7. Dividends to Common Shareholders (subsequent to October 31, 2008)

On November 11, 2008 and December 9, 2008, the Trust declared the following dividends from net investment income:


AMOUNT	RECORD	PAYABLE
PER SHARE	DATE	DATE
$0.060	November 21, 2008	November 28, 2008
$0.060	December 19, 2008	December 26, 2008

8. Purposes of and Risks Relating to Certain Financial Instruments

The Trust may invest a portion of its assets in inverse floating rate instruments, either through outright purchases of inverse floating rate securities or through the transfer of bonds to Dealer Trusts in exchange for cash and residual interests in the Dealer Trusts (See Note 1D). These investments are typically used by the Trust in seeking to enhance the yield of the portfolio or used as an alternative form of leverage in order to redeem a portion of the Trust’s preferred shares. These instruments typically involve greater risks than a fixed rate municipal bond. In particular, these instruments are acquired through leverage or may have leverage embedded in them and therefore involve many of the risks associated with leverage. Leverage is a speculative technique that may expose the Trust to greater risk and increased costs. Leverage may cause

Morgan Stanley Insured Municipal Income Trust

Notes to Financial Statements - October 31, 2008 continued

the Trust’s net asset value to be more volatile than if it had not been leveraged because leverage tends to magnify the effect of any increases or decreases in the value of the Trust’s portfolio securities. The use of leverage may also cause the Trust to liquidate portfolio positions when it may not be advantageous to do so in order to satisfy its obligations with respect to inverse floating rate instruments.

To hedge against adverse interest rate changes, the Trust may invest in financial futures contracts or municipal bond index futures contracts (“futures contracts”).

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

The Trust may enter into interest rate swaps and may purchase or sell interest rate caps, floors and collars. The Trust expects to enter into these transactions primarily to manage interest rate risk, hedge portfolio positions and preserve a return or spread on a particular investment or portion of its portfolio. The Trust may also enter into these transactions to protect against any increase in the price of securities the Trust anticipates purchasing at a later date. Interest rate swap transactions are subject to market risk, risk of default by the other party to the transaction, risk of imperfect correlation and manager risk. Such risks may exceed the related amounts shown in the Statement of Assets and Liabilities.

9. 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.

The tax character of distribution paid was as follows:


	FOR THE YEAR		FOR THE YEAR
	ENDED		ENDED
	OCTOBER 31, 2008		OCTOBER 31, 2007
Tax-exempt income	$	19,469,025	$	20,344,803
Ordinary income		145		—
Long-term capital gains		370,150		1,320,582

Total distributions	$	19,839,320	$	21,665,385

Morgan Stanley Insured Municipal Income Trust

Notes to Financial Statements - October 31, 2008 continued

As of October 31, 2008, the tax-basis components of accumulated losses were as follows:


Undistributed tax-exempt income	$	1,310,645
Undistributed long-term gains		2,195,980

Net accumulated earnings		3,506,625
Temporary differences		(126,313	)
Net unrealized depreciation		(39,603,361	)

Total accumulated losses	$	(36,223,049	)

As of October 31, 2008, the Trust had temporary book/tax differences primarily attributable to book amortization of discounts on debt securities, mark-to-market of open futures contracts, dividend payable and tax adjustments on inverse floaters.

Permanent differences, due to tax adjustments on debt securities sold by the Trust, resulted in the following reclassifications among the Trust’s components of net assets at October 31, 2008:


ACCUMULATED			ACCUMULATED
UNDISTRIBUTED			UNDISTRIBUTED
NET INVESTMENT			NET REALIZED
INCOME			GAIN		PAID-IN-CAPITAL

$	(54,163	)		$54,163		—

10. Accounting Pronouncements

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 Trust’s financial statement disclosures.

On March 19, 2008, FASB released Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB statement No. 133 (“SFAS 161”). SFAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The application of SFAS 161 is required for fiscal years beginning after November 15, 2008 and interim periods within those fiscal years. At this time, management is evaluating the implications of SFAS 161 and its impact on the Trust’s financial statements has not been determined.

Our procedures included confirmation of securities owned as of October 31, 2008, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Morgan Stanley Insured Municipal Income Trust as of October 31, 2008, the results of its operations and its cash flows 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 five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Morgan Stanley Insured Municipal Income Trust

Revised Investment Policies (unaudited)

While the Trust’s policy is to emphasize investments in municipal obligations with longer-term maturities because generally longer-term obligations, while more susceptible to market fluctuations resulting from changes in interest rates, produce higher yields than short-term obligations, the Trust no longer expects to maintain a specific average weighted maturity of its portfolio. As a result of changes in the fixed-income and municipal marketplace, the Trust’s average portfolio maturity will vary depending upon market conditions and other factors.

As previously stated in the Joint Proxy Statement dated October 1, 2008, which was distributed in connection with the November 14, 2008 Special Shareholder Meeting, the Trust may invest in options, futures, variable rate obligations and when-issued or delayed delivery securities as noted below.

Options and Futures The Trust may invest in options and futures. The Trust may use options and futures to protect against a decline in the Trust’s securities or an increase in prices of securities that may be purchased. If the Trust invests in options and/or futures, its participation in these markets would subject the Trust’s portfolio to certain risks. If the Investment Adviser’s predictions of movements in the direction of the markets are inaccurate, the adverse consequences to the Trust (e.g., a reduction in the Trust’s net asset value or a reduction in the amount of income available for distribution) may leave the Trust in a worse position than if these strategies were not used. Other risks inherent in the use of options and futures include, for example, the possible imperfect correlation between the price of options and futures contracts and movements in the prices of the securities being hedged and the possible absence of a liquid secondary market for any particular instrument. Certain options may be over-the-counter options which are options negotiated with dealers; there is no secondary market for these investments and they may be difficult to value.

Variable Rate Obligations The Trust may invest in Municipal Obligations of the type called variable rate obligations. The interest rate payable on a variable rate obligation is adjusted at predesignated periodic intervals. Other features may include the right whereby the Trust may demand prepayment of the principal amount of the obligation prior to its stated maturity (a “demand feature”) and the right of the issuer to prepay the principal amount prior to maturity. The principal benefit of a variable rate obligation is that the interest rate adjustment minimizes changes in the market value of the obligation. As a result, the purchase of variable rate obligations should enhance the ability of the Trust to maintain a stable net asset value per share and to sell obligations prior to maturity at a price that is approximately the full principal amount of the obligations. The principal benefit to the Trust of purchasing obligations with a demand feature is that liquidity, and the ability of the Trust to obtain repayment of the full principal amount of an obligation prior to maturity, is enhanced. The payment of principal and interest by issuers of certain obligations purchased by the Trust may be guaranteed by letters of credit or other credit facilities offered by banks or other financial

Morgan Stanley Insured Municipal Income Trust

Revised Investment Policies (unaudited) continued

institutions. Such guarantees will be considered in determining whether an obligation meets the Trust’s investment quality requirements.

When-Issued and Delayed Delivery Securities From time to time, the Trust may purchase securities on a when-issued or delayed delivery basis. When these transactions are negotiated, the price is fixed at the time of the commitment, but delivery and payment can take place a month or more after the date of commitment. The Trust may sell the securities before the settlement date, if it is deemed advisable. The securities so purchased or sold are subject to market fluctuation and no interest or dividends accrue to the purchaser prior to the settlement date. At the time the Trust makes the commitment to purchase or sell securities on a when-issued or delayed delivery basis, it will record the transaction and thereafter reflect the value, each day, of such security purchased, or if a sale, the proceeds to be received, in determining its net asset value. At the time of delivery of the securities, their value may be more or less than the purchase or sale price. An increase in the percentage of the Trust’s assets committed to the purchase of securities on a when-issued or delayed delivery basis may increase the volatility of its net asset value. The Trust will also establish a segregated account on the Trust’s books in which it will continually maintain cash or cash equivalents or other liquid portfolio securities equal in value to commitments to purchase securities on a when-issued or delayed delivery basis.

Dividend Reinvestment Plan (unaudited)

The dividend reinvestment plan (the “Plan”) offers you a prompt and simple way to reinvest your dividends and capital gains distributions into additional shares of the Trust. Under the Plan, the money you earn from dividends and capital gains distributions will be reinvested automatically in more shares of the Trust, allowing you to potentially increase your investment over time. All shareholders in the Trust are automatically enrolled in the Plan when shares are purchased.

Plan benefits

• Add to your account

You may increase your shares in the Trust easily and automatically with the Plan.

• Low transaction costs

Transaction costs are low because the new shares are bought in blocks and the brokerage commission is shared among all participants.

• Convenience

You will receive a detailed account statement from Computershare Trust Company, N.A., which administers the Plan, whenever shares are reinvested for you. The statement shows your total distributions, date of investment, shares acquired, and price per share, as well as the total number of shares in your reinvestment account. You can also access your account via the Internet. To do this, please go to morganstanley.com.

• Safekeeping

Computershare Trust Company, N.A. will hold the shares it has acquired for you in safekeeping.

How to participate in the Plan

If you own shares in your own name, you can participate directly in the Plan. If your shares are held in “street name” – in the name of your brokerage firm, bank, or other financial institution – you must instruct that entity to participate on your behalf. If they are unable to participate on your behalf, you may request that they reregister your shares in your own name so that you may enroll in the Plan.

If you choose to participate in the Plan, whenever the Trust declares a dividend or capital gains distributions, it will be invested in additional shares of your Trust that are purchased in the open market.

How to enroll

To enroll in the Plan, please read the Terms and Conditions in the Plan Brochure. You can obtain a copy of the Plan Brochure and enroll in the Plan by visiting morganstanley.com, calling toll-free (888) 4214015 or notifying us in writing at Morgan Stanley Closed-End Funds, Computershare Trust Company, N.A., P.O. Box 43078, Providence, Rl 02940-3078. Please include the Trust name and account number and ensure that all shareholders listed on the account sign these written instructions. Your participation in the Plan will begin

Morgan Stanley Insured Municipal Income Trust

Dividend Reinvestment Plan (unaudited) continued

with the next dividend or capital gains distribution payable after Computershare Trust Company, N.A. receives your authorization, as long as they receive it before the “record date,” which is generally ten business days before the dividend is paid. If your authorization arrives after such record date, your participation in the Plan will begin with the following dividend or distribution.

Costs of the Plan

There is no direct charge to you for reinvesting dividends and capital gains distributions because the Plan’s fees are paid by the Trust. However, when applicable, you will pay your portion of any brokerage commissions incurred when the new shares are purchased on the open market. These brokerage commissions are typically less than the standard brokerage charges for individual transactions, because shares are purchased for all participants in blocks, resulting in lower commissions for each individual participant. Any brokerage commissions or service fees are averaged into the purchase price.

Tax implications

The automatic reinvestment of dividends and capital gains distributions does not relieve you of any income tax that may be due on dividends or distributions. You will receive tax information annually to help you prepare your federal and state income tax returns.

Morgan Stanley does not offer tax advice. The tax information contained herein is general and is not exhaustive by nature. It was not intended or written to be used, and it cannot be used by any taxpayer, for avoiding penalties that may be imposed on the taxpayer under U.S. federal tax laws. Federal and state tax laws are complex and constantly changing. Shareholders should always consult a legal or tax advisor for information concerning their individual situation.

How to withdraw from the Plan

The Trust and Computershare Trust Company, N.A. may amend or terminate the Plan. Participants will receive written notice at least 30 days before the effective date of any amendment. In the case of termination, Participants will receive written notice at least 30 days before the record date for the payment of any dividend or capital gains distribution by the Trust. In the case of amendment or termination necessary or appropriate to comply with applicable law or the rules and policies of the Securities and Exchange Commission or any other regulatory authority, such written notice will not be required.

APPENDIX A

AUDIT COMMITTEE
AUDIT AND NON-AUDIT SERVICES
PRE-APPROVAL POLICY AND PROCEDURES
OF THE
MORGAN STANLEY RETAIL AND INSTITUTIONAL FUNDS

AS ADOPTED AND AMENDED JULY 23, 2004,¹

1. Statement of Principles

The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor’s independence from the Fund.

The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee’s administration of the engagement of the independent auditor. The SEC’s rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee (“general pre-approval”); or require the specific pre-approval of the Audit Committee or its delegate (“specific pre-approval”). The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors. As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee.

The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise. The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations.

The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities. It does not delegate the Audit Committee’s responsibilities to pre-approve services performed by the Independent Auditors to management.

The Fund’s Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors’ independence.


¹		This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the “Policy”), adopted as of the date above, supersedes and replaces all prior versions that may have been adopted from time to time.

2. Delegation

As provided in the Act and the SEC’s rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

3. Audit Services

The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee. Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund’s financial statements. These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit. The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items.

In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide. Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings.

The Audit Committee has pre-approved the Audit services in Appendix B.1. All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

4. Audit-related Services

Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund’s financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors. Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC’s rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services. Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters not classified as “Audit services”; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR.

The Audit Committee has pre-approved the Audit-related services in Appendix B.2. All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved

by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

5. Tax Services

The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor’s independence, and the SEC has stated that the Independent Auditors may provide such services.

Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

6. All Other Services

The Audit Committee believes, based on the SEC’s rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted. Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC’s rules on auditor independence.

The Audit Committee has pre-approved the All Other services in Appendix B.4. Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated).

7. Pre-Approval Fee Levels or Budgeted Amounts

Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee. The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services.

8. Procedures

All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund’s Chief Financial Officer and must include a detailed description of the services to be rendered. The Fund’s Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors. Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund’s Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC’s rules on auditor independence.

The Audit Committee has designated the Fund’s Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy. The Fund’s Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring. Both the Fund’s Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund’s Chief Financial Officer or any member of management.

9. Additional Requirements

The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor’s independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence.

10. Covered Entities

Covered Entities include the Fund’s investment adviser(s) and any entity controlling, controlled by or under common control with the Fund’s investment adviser(s) that provides ongoing services to the Fund(s). Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund’s audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund. This list of Covered Entities would include:

(f) Not applicable.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

The Fund’s/Trust’s and its Investment Advisor’s Proxy Voting Policies and Procedures are as follows:

FEBRUARY 28, 2008

MORGAN STANLEY INVESTMENT MANAGEMENT
PROXY VOTING POLICY AND PROCEDURES

I. POLICY STATEMENT

Introduction — Morgan Stanley Investment Management’s (“MSIM”) policy and procedures for voting proxies (“Policy”) with respect to securities held in the accounts of clients applies to those MSIM entities that provide discretionary investment management services and for which an MSIM entity has authority to vote proxies. This Policy is reviewed and updated as necessary to address new and evolving proxy voting issues and standards.

The MSIM entities covered by this Policy currently include the following: Morgan Stanley Investment Advisors Inc., Morgan Stanley AIP GP LP, Morgan Stanley Investment Management Inc., Morgan Stanley Investment Management Limited, Morgan Stanley Investment Management Company, Morgan Stanley Asset & Investment Trust Management Co., Limited, Morgan Stanley Investment Management Private Limited, Van Kampen Asset Management, and Van Kampen Advisors Inc. (each an “MSIM Affiliate” and collectively referred to as the “MSIM Affiliates” or as “we” below).

Each MSIM Affiliate will use its best efforts to vote proxies as part of its authority to manage, acquire and dispose of account assets. With respect to the MSIM registered management investment companies (Van Kampen, Institutional and Advisor Funds—collectively referred to herein as the “MSIM Funds”), each MSIM Affiliate will vote proxies under this Policy pursuant to authority granted under its applicable investment advisory agreement or, in the absence of such authority, as authorized by the Board of Directors/Trustees of the MSIM Funds. An MSIM Affiliate will not vote proxies if the “named fiduciary” for an ERISA account has reserved the authority for itself, or in the case of an account not governed by ERISA, the investment management or investment advisory agreement does not authorize the MSIM Affiliate to vote proxies. MSIM Affiliates will vote proxies in a prudent and diligent manner and in the best interests of clients, including beneficiaries of and participants in a client’s benefit plan(s) for which the MSIM Affiliates manage assets, consistent with the objective of maximizing long-term investment returns (“Client Proxy Standard”). In certain situations, a client or its fiduciary may provide an MSIM Affiliate with a proxy voting policy. In these situations, the MSIM Affiliate will comply with the client’s policy.

Proxy Research Services — RiskMetrics Group ISS Governance Services (“ISS”) and Glass Lewis (together with other proxy research providers as we may retain from time to time, the “Research Providers”) are independent advisers that specialize in providing a variety of fiduciary-level proxy-related services to institutional investment managers, plan sponsors, custodians, consultants, and other institutional investors. The services

provided include in-depth research, global issuer analysis, and voting recommendations. While we may review and utilize the recommendations of the Research Providers in making proxy voting decisions, we are in no way obligated to follow such recommendations. In addition to research, ISS provides vote execution, reporting, and recordkeeping.

Voting Proxies for Certain Non-U.S. Companies — Voting proxies of companies located in some jurisdictions, particularly emerging markets, may involve several problems that can restrict or prevent the ability to vote such proxies or entail significant costs. These problems include, but are not limited to: (i) proxy statements and ballots being written in a language other than English; (ii) untimely and/or inadequate notice of shareholder meetings; (iii) restrictions on the ability of holders outside the issuer’s jurisdiction of organization to exercise votes; (iv) requirements to vote proxies in person; (v) the imposition of restrictions on the sale of the securities for a period of time in proximity to the shareholder meeting; and (vi) requirements to provide local agents with power of attorney to facilitate our voting instructions. As a result, we vote clients’ non-U.S. proxies on a best efforts basis only, after weighing the costs and benefits of voting such proxies, consistent with the Client Proxy Standard. ISS has been retained to provide assistance in connection with voting non-U.S. proxies.

II. GENERAL PROXY VOTING GUIDELINES

To promote consistency in voting proxies on behalf of its clients, we follow this Policy (subject to any exception set forth herein), including the guidelines set forth below. These guidelines address a broad range of issues, and provide general voting parameters on proposals that arise most frequently. However, details of specific proposals vary, and those details affect particular voting decisions, as do factors specific to a given company. Pursuant to the procedures set forth herein, we may vote in a manner that is not in accordance with the following general guidelines, provided the vote is approved by the Proxy Review Committee (see Section III for description) and is consistent with the Client Proxy Standard. Morgan Stanley AIP GP LP will follow the procedures as described in Appendix A.

We endeavor to integrate governance and proxy voting policy with investment goals and to follow the Client Proxy Standard for each client. At times, this may result in split votes, for example when different clients have varying economic interests in the outcome of a particular voting matter (such as a case in which varied ownership interests in two companies involved in a merger result in different stakes in the outcome). We also may split votes at times based on differing views of portfolio managers, but such a split vote must be approved by the Proxy Review Committee.

We may abstain on matters for which disclosure is inadequate.

A. Routine Matters. We generally support routine management proposals. The following are examples of routine management proposals:

	•		Approval of financial statements and auditor reports.

	•		General updating/corrective amendments to the charter, articles of association or bylaws.

	•		Most proposals related to the conduct of the annual meeting, with the following exceptions. We generally oppose proposals that relate to “the transaction of such other business which may come before the meeting,” and open-ended requests for adjournment. However, where management specifically states the reason for requesting an adjournment and the requested adjournment would facilitate passage of a proposal that would otherwise be supported under this Policy (i.e. an uncontested corporate transaction), the adjournment request will be supported.

We generally support shareholder proposals advocating confidential voting procedures and independent tabulation of voting results.

B. Board of Directors

Election of directors: In the absence of a proxy contest, we generally support the board’s nominees for director except as follows:

We consider withholding support from or voting against interested directors if the company’s board does not meet market standards for director independence, or if otherwise we believe board independence is insufficient. We refer to prevalent market standards as promulgated by a stock exchange or other authority within a given market (e.g., New York Stock Exchange or Nasdaq rules for most U.S. companies, and The Combined Code on Corporate Governance in the United Kingdom). Thus, for an NYSE company with no controlling shareholder, we would expect that at a minimum a majority of directors should be independent as defined by NYSE. Where we view market standards as inadequate, we may withhold votes based on stronger independence standards. Market standards notwithstanding, we generally do not view long board tenure alone as a basis to classify a director as non-independent, although lack of board turnover and fresh perspective can be a negative factor in voting on directors.

At a company with a shareholder or group that controls the company by virtue of a majority economic interest in the company, we have a reduced expectation for board independence, although we believe the presence of independent directors can be helpful, particularly in staffing the audit committee, and at times we may withhold support from or vote against a nominee on the view the board or its committees are not sufficiently independent.

ii.

We consider withholding support from or voting against a nominee if he or she is affiliated with a major shareholder that has representation on a board disproportionate to its economic interest.

	b.		Depending on market standards, we consider withholding support from or voting against a nominee who is interested and who is standing for election as a member of the company’s compensation, nominating or audit committee.

	c.		We consider withholding support from or voting against a nominee if we believe a direct conflict exists between the interests of the nominee and the public shareholders, including failure to meet fiduciary standards of care and/or loyalty. We may oppose directors where we conclude that actions of directors are unlawful, unethical or negligent. We consider opposing individual board members or an entire slate if we believe the board is entrenched and/or dealing inadequately with performance problems, and/or acting with insufficient independence between the board and management.

	d.		We consider withholding support from or voting against a nominee standing for election if the board has not taken action to implement generally accepted governance practices for which there is a “bright line” test. For example, in the context of the U.S. market, failure to eliminate a dead hand or slow hand poison pills would be seen as a basis for opposing one or more incumbent nominees.

	e.		In markets that encourage designated audit committee financial experts, we consider voting against members of an audit committee if no members are designated as such.

	f.		We consider withholding support from or voting against a nominee who has failed to attend at least 75% of board meetings within a given year without a reasonable excuse.

	g.		We consider withholding support from or voting against a nominee who serves on the board of directors of more than six companies (excluding investment companies). We also consider voting against a director who otherwise appears to have too many commitments to serve adequately on the board of the company.

Board independence: We generally support U.S. shareholder proposals requiring that a certain percentage (up to 66²/₃%) of the company’s board members be independent directors, and promoting all-independent audit, compensation and nominating/governance committees.

	3.		Board diversity: We consider on a case-by-case basis shareholder proposals urging diversity of board membership with respect to social, religious or ethnic group.

	4.		Majority voting: We generally support proposals requesting or requiring majority voting policies in election of directors, so long as there is a carve-out for plurality voting in the case of contested elections.

	5.		Proxy access: We consider on a case-by-case basis shareholder proposals to provide procedures for inclusion of shareholder nominees in company proxy statements.

	6.		Proposals to elect all directors annually: We generally support proposals to elect all directors annually at public companies (to “declassify” the Board of Directors) where such action is supported by the board, and otherwise consider the issue on a case-by-case basis based in part on overall takeover defenses at a company.

	7.		Cumulative voting: We generally support proposals to eliminate cumulative voting in the U.S. market context. (Cumulative voting provides that shareholders may concentrate their votes for one or a handful of candidates, a system that can enable a minority bloc to place representation on a board). U.S. proposals to establish cumulative voting in the election of directors generally will not be supported.

	8.		Separation of Chairman and CEO positions: We vote on shareholder proposals to separate the Chairman and CEO positions and/or to appoint a non-executive Chairman based in part on prevailing practice in particular markets, since the context for such a practice varies. In many non-U.S. markets, we view separation of the roles as a market standard practice, and support division of the roles in that context.

	9.		Director retirement age and term limits: Proposals recommending set director retirement ages or director term limits are voted on a case-by-case basis.

	10.		Proposals to limit directors’ liability and/or broaden indemnification of directors. Generally, we will support such proposals provided that the officers and directors are eligible for indemnification and liability protection if they have acted in good faith on company business and were found innocent of any civil or criminal charges for duties performed on behalf of the company.

C. Corporate transactions and proxy fights. We examine proposals relating to mergers, acquisitions and other special corporate transactions (i.e., takeovers, spin-offs, sales of assets, reorganizations, restructurings and recapitalizations) on a case-by-case basis. However, proposals for mergers or other significant transactions that are friendly and approved by the Research Providers generally will be supported and in those instances will not need to be reviewed by the Proxy Review Committee, where there is no

portfolio manager objection and where there is no material conflict of interest. We also analyze proxy contests on a case-by-case basis.

D. Changes in capital structure.

We generally support the following:

	•		Management and shareholder proposals aimed at eliminating unequal voting rights, assuming fair economic treatment of classes of shares we hold.

	•		Management proposals to increase the authorization of existing classes of common stock (or securities convertible into common stock) if: (i) a clear business purpose is stated that we can support and the number of shares requested is reasonable in relation to the purpose for which authorization is requested; and/or (ii) the authorization does not exceed 100% of shares currently authorized and at least 30% of the total new authorization will be outstanding.

	•		Management proposals to create a new class of preferred stock or for issuances of preferred stock up to 50% of issued capital, unless we have concerns about use of the authority for anti-takeover purposes.

	•		Management proposals to authorize share repurchase plans, except in some cases in which we believe there are insufficient protections against use of an authorization for anti-takeover purposes.

	•		Management proposals to reduce the number of authorized shares of common or preferred stock, or to eliminate classes of preferred stock.

	•		Management proposals to effect stock splits.

	•		Management proposals to effect reverse stock splits if management proportionately reduces the authorized share amount set forth in the corporate charter. Reverse stock splits that do not adjust proportionately to the authorized share amount generally will be approved if the resulting increase in authorized shares coincides with the proxy guidelines set forth above for common stock increases.

	•		Management proposals for higher dividend payouts.

We generally oppose the following (notwithstanding management support):

•

Proposals to add classes of stock that would substantially dilute the voting interests of existing shareholders.

	•		Proposals to increase the authorized or issued number of shares of existing classes of stock that are unreasonably dilutive, particularly if there are no preemptive rights for existing shareholders.

	•		Proposals that authorize share issuance at a discount to market rates, except where authority for such issuance is de minimis, or if there is a special situation that we believe justifies such authorization (as may be the case, for example, at a company under severe stress and risk of bankruptcy).

	•		Proposals relating to changes in capitalization by 100% or more.

We consider on a case-by-case basis shareholder proposals to increase dividend payout ratios, in light of market practice and perceived market weaknesses, as well as individual company payout history and current circumstances. For example, currently we perceive low payouts to shareholders as a concern at some Japanese companies, but may deem a low payout ratio as appropriate for a growth company making good use of its cash, notwithstanding the broader market concern.

E. Takeover Defenses and Shareholder Rights

	1.		Shareholder rights plans: We generally support proposals to require shareholder approval or ratification of shareholder rights plans (poison pills). In voting on rights plans or similar takeover defenses, we consider on a case-by-case basis whether the company has demonstrated a need for the defense in the context of promoting long-term share value; whether provisions of the defense are in line with generally accepted governance principles; and the specific context if the proposal is made in the midst of a takeover bid or contest for control.

	2.		Supermajority voting requirements: We generally oppose requirements for supermajority votes to amend the charter or bylaws, unless the provisions protect minority shareholders where there is a large shareholder. In line with this view, in the absence of a large shareholder we support reasonable shareholder proposals to limit such supermajority voting requirements.

	3.		Shareholder rights to call meetings: We consider proposals to enhance shareholder rights to call meetings on a case-by-case basis.

	4.		Reincorporation: We consider management and shareholder proposals to reincorporate to a different jurisdiction on a case-by-case basis. We oppose such proposals if we believe the main purpose is to take advantage of laws or judicial precedents that reduce shareholder rights.

	5.		Anti-greenmail provisions: Proposals relating to the adoption of anti-greenmail provisions will be supported, provided that the proposal: (i) defines greenmail; (ii) prohibits buyback offers to large block holders (holders of at least 1% of the

outstanding shares and in certain cases, a greater amount, as determined by the Proxy Review Committee) not made to all shareholders or not approved by disinterested shareholders; and (iii) contains no anti-takeover measures or other provisions restricting the rights of shareholders.

Bundled proposals: We may consider opposing or abstaining on proposals if disparate issues are “bundled” and presented for a single vote.

F. Auditors. We generally support management proposals for selection or ratification of independent auditors. However, we may consider opposing such proposals with reference to incumbent audit firms if the company has suffered from serious accounting irregularities and we believe rotation of the audit firm is appropriate, or if fees paid to the auditor for non-audit-related services are excessive. Generally, to determine if non-audit fees are excessive, a 50% test will be applied (i.e., non-audit-related fees should be less than 50% of the total fees paid to the auditor). We generally vote against proposals to indemnify auditors.

G. Executive and Director Remuneration.

We generally support the following proposals:

	•		Proposals for employee equity compensation plans and other employee ownership plans, provided that our research does not indicate that approval of the plan would be against shareholder interest. Such approval may be against shareholder interest if it authorizes excessive dilution and shareholder cost, particularly in the context of high usage (“run rate”) of equity compensation in the recent past; or if there are objectionable plan design and provisions.

	•		Proposals relating to fees to outside directors, provided the amounts are not excessive relative to other companies in the country or industry, and provided that the structure is appropriate within the market context. While stock-based compensation to outside directors is positive if moderate and appropriately structured, we are wary of significant stock option awards or other performance-based awards for outside directors, as well as provisions that could result in significant forfeiture of value on a director’s decision to resign from a board (such forfeiture can undercut director independence).

	•		Proposals for employee stock purchase plans that permit discounts up to 15%, but only for grants that are part of a broad-based employee plan, including all non-executive employees.

•

Proposals for the establishment of employee retirement and severance plans, provided that our research does not indicate that approval of the plan would be against shareholder interest.

	2.		Shareholder proposals requiring shareholder approval of all severance agreements will not be supported, but proposals that require shareholder approval for agreements in excess of three times the annual compensation (salary and bonus) generally will be supported. We generally oppose shareholder proposals that would establish arbitrary caps on pay. We consider on a case-by-case basis shareholder proposals that seek to limit Supplemental Executive Retirement Plans (SERPs), but support such proposals where we consider SERPs to be excessive.

	3.		Shareholder proposals advocating stronger and/or particular pay-for-performance models will be evaluated on a case-by-case basis, with consideration of the merits of the individual proposal within the context of the particular company and its labor markets, and the company’s current and past practices. While we generally support emphasis on long-term components of senior executive pay and strong linkage of pay to performance, we consider whether a proposal may be overly prescriptive, and the impact of the proposal, if implemented as written, on recruitment and retention.

	4.		We consider shareholder proposals for U.K.-style advisory votes on pay on a case-by-case basis.

	5.		We generally support proposals advocating reasonable senior executive and director stock ownership guidelines and holding requirements for shares gained in option exercises.

	6.		Management proposals effectively to re-price stock options are considered on a case-by-case basis. Considerations include the company’s reasons and justifications for a re-pricing, the company’s competitive position, whether senior executives and outside directors are excluded, potential cost to shareholders, whether the re-pricing or share exchange is on a value-for-value basis, and whether vesting requirements are extended.

H. Social, Political and Environmental Issues. We consider proposals relating to social, political and environmental issues on a case-by-case basis to determine whether they will have a financial impact on shareholder value. However, we generally vote against proposals requesting reports that are duplicative, related to matters not material to the business, or that would impose unnecessary or excessive costs. We may abstain from voting on proposals that do not have a readily determinable financial impact on

shareholder value. We generally oppose proposals requiring adherence to workplace standards that are not required or customary in market(s) to which the proposals relate.

I. Fund of Funds. Certain Funds advised by an MSIM Affiliate invest only in other MSIM Funds. If an underlying fund has a shareholder meeting, in order to avoid any potential conflict of interest, such proposals will be voted in the same proportion as the votes of the other shareholders of the underlying fund, unless otherwise determined by the Proxy Review Committee.

III. ADMINISTRATION OF POLICY

The MSIM Proxy Review Committee (the “Committee”) has overall responsibility for creating and implementing the Policy, working with an MSIM staff group (the “Corporate Governance Team”). The Committee, which is appointed by MSIM’s Chief Investment Officer of Global Equities (“CIO”), consists of senior investment professionals who represent the different investment disciplines and geographic locations of the firm. Because proxy voting is an investment responsibility and impacts shareholder value, and because of their knowledge of companies and markets, portfolio managers and other members of investment staff play a key role in proxy voting, although the Committee has final authority over proxy votes.

The Committee Chairperson is the head of the Corporate Governance Team, and is responsible for identifying issues that require Committee deliberation or ratification. The Corporate Governance Team, working with advice of investment teams and the Committee, is responsible for voting on routine items and on matters that can be addressed in line with these Policy guidelines. The Corporate Governance Team has responsibility for voting case-by-case where guidelines and precedent provide adequate guidance, and to refer other case-by-case decisions to the Proxy Review Committee.

The Committee will periodically review and have the authority to amend, as necessary, the Policy and establish and direct voting positions consistent with the Client Proxy Standard.

A. Committee Procedures

The Committee will meet at least monthly to (among other matters) address any outstanding issues relating to the Policy or its implementation. The Corporate Governance Team will timely communicate to ISS MSIM’s Policy (and any amendments and/or any additional guidelines or procedures the Committee may adopt).

The Committee will meet on an ad hoc basis to (among other matters): (1) authorize “split voting” (i.e., allowing certain shares of the same issuer that are the subject of the same proxy solicitation and held by one or more MSIM portfolios to be voted differently than other shares) and/or “override voting” (i.e., voting all MSIM portfolio shares in a manner contrary to the Policy); (2) review and approve upcoming votes, as appropriate, for matters for which specific direction has been provided in this Policy; and (3)

determine how to vote matters for which specific direction has not been provided in this Policy.

Members of the Committee may take into account Research Providers’ recommendations and research as well as any other relevant information they may request or receive, including portfolio manager and/or analyst research, as applicable. Generally, proxies related to securities held in accounts that are managed pursuant to quantitative, index or index-like strategies (“Index Strategies”) will be voted in the same manner as those held in actively managed accounts, unless economic interests of the accounts differ. Because accounts managed using Index Strategies are passively managed accounts, research from portfolio managers and/or analysts related to securities held in these accounts may not be available. If the affected securities are held only in accounts that are managed pursuant to Index Strategies, and the proxy relates to a matter that is not described in this Policy, the Committee will consider all available information from the Research Providers, and to the extent that the holdings are significant, from the portfolio managers and/or analysts.

B. Material Conflicts of Interest

In addition to the procedures discussed above, if the Committee determines that an issue raises a material conflict of interest, the Committee will request a special committee to review, and recommend a course of action with respect to, the conflict(s) in question (“Special Committee”).

The Special Committee shall be comprised of the Chairperson of the Proxy Review Committee, the Chief Compliance Officer or his/her designee, a senior portfolio manager (if practicable, one who is a member of the Proxy Review Committee) designated by the Proxy Review Committee, and MSIM’s relevant Chief Investment Officer or his/her designee, and any other persons deemed necessary by the Chairperson. The Special Committee may request the assistance of MSIM’s General Counsel or his/her designee who will have sole discretion to cast a vote. In addition to the research provided by Research Providers, the Special Committee may request analysis from MSIM Affiliate investment professionals and outside sources to the extent it deems appropriate.

C. Identification of Material Conflicts of Interest

A potential material conflict of interest could exist in the following situations, among others:

	1.		The issuer soliciting the vote is a client of MSIM or an affiliate of MSIM and the vote is on a material matter affecting the issuer.

	2.		The proxy relates to Morgan Stanley common stock or any other security issued by Morgan Stanley or its affiliates except if echo voting is used, as with MSIM Funds, as described herein.

Morgan Stanley has a material pecuniary interest in the matter submitted for a vote (e.g., acting as a financial advisor to a party to a merger or acquisition for which Morgan Stanley will be paid a success fee if completed).

If the Chairperson of the Committee determines that an issue raises a potential material conflict of interest, depending on the facts and circumstances, the Chairperson will address the issue as follows:

	1.		If the matter relates to a topic that is discussed in this Policy, the proposal will be voted as per the Policy.

	2.		If the matter is not discussed in this Policy or the Policy indicates that the issue is to be decided case-by-case, the proposal will be voted in a manner consistent with the Research Providers, provided that all the Research Providers have the same recommendation, no portfolio manager objects to that vote, and the vote is consistent with MSIM’s Client Proxy Standard.

	3.		If the Research Providers’ recommendations differ, the Chairperson will refer the matter to the Committee to vote on the proposal. If the Committee determines that an issue raises a material conflict of interest, the Committee will request a Special Committee to review and recommend a course of action, as described above. Notwithstanding the above, the Chairperson of the Committee may request a Special Committee to review a matter at any time as he/she deems necessary to resolve a conflict.

D. Proxy Voting Reporting

The Committee and the Special Committee, or their designee(s), will document in writing all of their decisions and actions, which documentation will be maintained by the Committee and the Special Committee, or their designee(s), for a period of at least 6 years. To the extent these decisions relate to a security held by an MSIM Fund, the Committee and Special Committee, or their designee(s), will report their decisions to each applicable Board of Trustees/Directors of those Funds at each Board’s next regularly scheduled Board meeting. The report will contain information concerning decisions made by the Committee and Special Committee during the most recently ended calendar quarter immediately preceding the Board meeting.

The Corporate Governance Team will timely communicate to applicable portfolio managers and to ISS, decisions of the Committee and Special Committee so that, among other things, ISS will vote proxies consistent with their decisions.

MSIM will promptly provide a copy of this Policy to any client requesting it. MSIM will also, upon client request, promptly provide a report indicating how each proxy was voted with respect to securities held in that client’s account.

MSIM’s Legal Department is responsible for filing an annual Form N-PX on behalf of each MSIM Fund for which such filing is required, indicating how all proxies were voted with respect to such Fund’s holdings.

APPENDIX A

The following procedures apply to accounts managed by Morgan Stanley AIP GP LP (“AIP”).

Generally, AIP will follow the guidelines set forth in Section II of MSIM’s Proxy Voting Policy and Procedures. To the extent that such guidelines do not provide specific direction, or AIP determines that consistent with the Client Proxy Standard, the guidelines should not be followed, the Proxy Review Committee has delegated the voting authority to vote securities held by accounts managed by AIP to the Liquid Markets investment team and the Private Markets investment team of AIP. A summary of decisions made by the investment teams will be made available to the Proxy Review Committee for its information at the next scheduled meeting of the Proxy Review Committee.

In certain cases, AIP may determine to abstain from determining (or recommending) how a proxy should be voted (and therefore abstain from voting such proxy or recommending how such proxy should be voted), such as where the expected cost of giving due consideration to the proxy does not justify the potential benefits to the affected account(s) that might result from adopting or rejecting (as the case may be) the measure in question.

Waiver of Voting Rights

For regulatory reasons, AIP may either 1) invest in a class of securities of an underlying fund (the “Fund”) that does not provide for voting rights; or 2) waive 100% of its voting rights with respect to the following:

	1.		Any rights with respect to the removal or replacement of a director, general partner, managing member or other person acting in a similar capacity for or on behalf of the Fund (each individually a “Designated Person,” and collectively, the “Designated Persons”), which may include, but are not limited to, voting on the election or removal of a Designated Person in the event of such Designated Person’s death, disability, insolvency, bankruptcy, incapacity, or other event requiring a vote of interest holders of the Fund to remove or replace a Designated Person; and

	2.		Any rights in connection with a determination to renew, dissolve, liquidate, or otherwise terminate or continue the Fund, which may include, but are not limited to, voting on the renewal, dissolution, liquidation, termination or continuance of the Fund upon the occurrence of an event described in the Fund’s organizational documents; provided, however, that, if the Fund’s organizational documents

require the consent of the Fund’s general partner or manager, as the case may be, for any such termination or continuation of the Fund to be effective, then AIP may exercise its voting rights with respect to such matter.

Item 8. Portfolio Managers of Closed-End Management Investment Companies

Applicable only to reports covering periods ending on or after December 31, 2005.

Morgan Stanley Insured Municipal Income Trust (IIM)
Fund Management

PORTFOLIO MANAGEMENT. As of the date of this report, the Fund is managed within the Morgan Stanley Municipals team. The team consists of portfolio managers and analysts. Current members of the team jointly and primarily responsible for the day-to-day management of the Fund’s portfolio are Neil Stone and Steven K. Kreider, each a Managing Director of the Investment Adviser.

Mr. Stone has been associated with the Investment Adviser in an investment management capacity since March 1995 and began managing the Fund in September 2007. Mr. Kreider has been associated with the Investment Adviser in an investment management capacity since February 1988 and began managing the Fund in September 2007.

The composition of the team may change from time to time.

OTHER ACCOUNTS MANAGED BY THE PORTFOLIO MANAGERS

The following information is as of October 31, 2008:

Neil Stone managed 20 registered investment companies with a total of approximately $7.3 billion in assets; no pooled investment vehicles other than registered investment companies; and 42 other accounts with a total of approximately $9.0 billion in assets.

Steven K. Kreider managed 40 registered investment companies with a total of approximately $25.9 billion in assets; two pooled investment vehicles other than registered investment companies with a total of approximately $202.3 million; and 41 other accounts with a total of approximately $6.4 billion in assets.

Because the portfolio managers manage assets for other investment companies, pooled investment vehicles and/or other accounts (including institutional clients, pension plans and certain high net worth individuals), there may be an incentive to favor one client over another resulting in conflicts of interest. For instance, the Investment Adviser may receive fees from certain accounts that are higher than the fee it receives from the Fund, or it may receive a performance-based fee on certain accounts. In those instances, the portfolio managers may have an incentive to favor the higher and/or performance-based fee accounts over the Fund. In addition, a conflict of interest could exist to the extent the Investment Adviser has proprietary investments in certain accounts, where portfolio managers have personal investments in certain accounts or when certain accounts are investment options in the Investment Adviser’s employee benefits and/or deferred compensation plans. The portfolio manager may have an incentive to favor these accounts over others. If the Investment Adviser manages accounts that engage in short sales of securities of the type in which the Fund invests, the Investment Adviser could be seen as harming the performance of the Fund for

the benefit of the accounts engaging in short sales if the short sales cause the market value of the securities to fall. The Investment Adviser has adopted trade allocation and other policies and procedures that it believes are reasonably designed to address these and other conflicts of interest.

PORTFOLIO MANAGER COMPENSATION STRUCTURE

Portfolio managers receive a combination of base compensation and discretionary compensation, comprising a cash bonus and several deferred compensation programs described below. The methodology used to determine portfolio manager compensation is applied across all funds/accounts managed by the portfolio managers.

BASE SALARY COMPENSATION. Generally, portfolio managers receive base salary compensation based on the level of their position with the Investment Adviser.

DISCRETIONARY COMPENSATION. In addition to base compensation, portfolio managers may receive discretionary compensation.

Discretionary compensation can include:

	•		Cash Bonus.

	•		Morgan Stanley’s Long Term Incentive Compensation awards — a mandatory program that defers a portion of discretionary year-end compensation into restricted stock units or other awards based on Morgan Stanley common stock or other investments that are subject to vesting and other conditions.

	•		Investment Management Alignment Plan (IMAP) awards — a mandatory program that defers a portion of discretionary year-end compensation and notionally invests it in designated funds advised by the Investment Adviser or its affiliates. The award is subject to vesting and other conditions. Portfolio managers must notionally invest a minimum of 25% to a maximum of 100% of the IMAP deferral into a combination of the designated funds they manage that are included in the IMAP fund menu, which may or may not include the Fund.

	•		Voluntary Deferred Compensation Plans — voluntary programs that permit certain employees to elect to defer a portion of their discretionary year-end compensation and directly or notionally invest the deferred amount: (1) across a range of designated investment funds, including funds advised by the Investment Adviser or its affiliates; and/or (2) in Morgan Stanley stock units.

Several factors determine discretionary compensation, which can vary by portfolio management team and circumstances. In order of relative importance, these factors include:

	•		Investment performance. A portfolio manager’s compensation is linked to the pre-tax investment performance of the funds/accounts managed by the portfolio manager. Investment performance is calculated for one-, three- and five-year periods measured against a fund’s/account’s primary benchmark (as set forth in the fund’s prospectus), indices and/or peer groups where applicable. Generally, the greatest weight is placed on the three- and five-year periods.

	•		Revenues generated by the investment companies, pooled investment vehicles and other accounts managed by the portfolio manager.

	•		Contribution to the business objectives of the Investment Adviser.

	•		The dollar amount of assets managed by the portfolio manager.

	•		Market compensation survey research by independent third parties.

	•		Other qualitative factors, such as contributions to client objectives.

	•		Performance of Morgan Stanley and Morgan Stanley Investment Management, and the overall performance of the investment team(s) of which the portfolio manager is a member.
