Trust Performance

Performance summary

Cumulative total returns, 3/31/10 to 9/30/10.

Trust at NAV	7.73	%
Trust at Market Value	14.98
Market Price Premium to NAV	1.80

The performance data quoted represent past performance and cannot guarantee comparable future results; current performance may be lower or higher. Investment return, net asset value and common share market price will fluctuate so that you may have a gain or loss when you sell shares. Please visit invesco.com/performance for the most recent month-end performance. Performance figures reflect fund expenses, the reinvestment of distributions (if any) and changes in net asset value (NAV) for performance based on NAV and changes in market price for performance based on market price.

     Since the Fund is a closed-end management investment company, shares of the Fund may trade at a discount or premium from the NAV. This characteristic is separate and distinct from the risk that NAV could decrease as a result of investment activities and may be a greater risk to investors expecting to sell their shares after a short time. The Fund cannot predict whether shares will trade at, above or below NAV. The Fund should not be viewed as a vehicle for trading purposes. It is designed primarily for risk-tolerant long-term investors.

Letters to Shareholders

Bruce Crockett

Dear Fellow Shareholders:

Although the global markets have improved since their lows of 2009, they remain challenging as governments around the world work to ensure the recovery remains on track. In this volatile environment, it’s comforting to know that your Board is committed to putting your interests first. We realize you have many choices when selecting a money manager, and your Board is working hard to ensure you feel you’ve made the right choice.

     To that end, I’m pleased to share the news that Invesco has completed its acquisition of Morgan Stanley’s retail asset management business, including Van Kampen Investments. This acquisition greatly expands the breadth and depth of investment strategies we can offer you. Another key advantage of this combination is the highly complementary nature of our cultures. This is making it much easier to bring our organizations together while ensuring that our investment teams remain focused on managing your money.

     We view this addition as an excellent opportunity for you, our shareholders, to have access to an even broader range of well-diversified mutual funds. Now that the acquisition has closed, Invesco is working to bring the full value of the combined organization to shareholders. The key goals of this effort are to ensure that we have deeply resourced and focused investment teams, a compelling line of products and enhanced efficiency, which will benefit our shareholders now and over the long term.

     It might interest you to know that the mutual funds of the combined organization are overseen by a single fund Board composed of 17 current members, including four new members who joined us from Van Kampen/Morgan Stanley. This expanded Board will continue to oversee the funds with the same strong sense of responsibility for your money and your continued trust that we have always maintained.

     As always, you are welcome to contact me at bruce@brucecrockett.com with any questions or concerns you may have. We look forward to representing you and serving your interests.

Sincerely,

Bruce L. Crockett
Independent Chair, Invesco Funds Board of Trustees

Philip Taylor

Dear Shareholders:

Enclosed is important information about your Trust and its performance. I hope you find it useful. Whether you’re a long-time Invesco client or a shareholder who joined us as a result of our June 1 acquisition of Morgan Stanley’s retail asset management business, including Van Kampen Investments, I’m glad you’re part of the Invesco family.

     At Invesco, we’re committed to providing you with timely information about market conditions, answering questions you may have about your investments and offering outstanding customer service. At our website, invesco.com/us, you can obtain unique market perspectives, useful investor education information and your Fund’s most recent quarterly commentary.

     I believe Invesco, as a leading global investment manager, is uniquely positioned to serve your needs.

     We are committed to investment excellence. We believe the best investment insights come from specialized investment teams with discrete investment perspectives, each operating under a disciplined philosophy and process with strong risk oversight and quality controls.

     We have just one focus: investment management. At Invesco, we believe that focus brings success, and that’s why investment management is all we do.

     If you have questions about your account, please contact one of our client services representatives at 800 341 2929. If you have a general Invesco-related question or comment for me, please email me directly at phil@invesco.com.

     Thank you for investing with us.

Philip Taylor
Senior Managing Director, Invesco

Dividend Reinvestment Plan

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

Plan benefits

n	Add to your account
	You may increase the amount of shares in your Trust easily and automatically with the Plan.
n	Low transaction costs
	Transaction costs are low because the new shares are bought in blocks and the brokerage commission is shared among all participants.
n	Convenience
	You will receive a detailed account statement from Computershare Trust Company, N.A. (the Agent) which administers the Plan. 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 invesco.com.
n	Safekeeping
	The Agent 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.

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 invesco.com, calling toll-free 800 341 2929 or notifying us in writing at Invesco Closed-End Funds ComputershareTrust Company, N.A. P.O. Box 43078, Providence, RI 02940-3078. Please include your 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 with the next Distribution payable after the Agent receives your authorization, as long as they receive it before the “record date,” which is generally one week before such Distributions are paid. If your authorization arrives after such record date, your participation in the Plan will begin with the following Distributions.

How the Plan Works

If you choose to participate in the Plan, whenever your Trust declares such Distributions, it will be invested in additional shares of your Trust that are purchased on the open market.

Costs of the Plan

There is no direct charge to you for reinvesting Distributions because the Plan’s fees are paid by your Trust. However, you will pay your portion of any per share fees incurred when the new shares are purchased on the open market. These fees 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 per share or service fees are averaged into the purchase price. Per share fees include any applicable brokerage commissions the Agent is required to pay.

Tax implications

The automatic reinvestment of Distributions does not relieve you of any income tax that may be due on Distributions. You will receive tax information annually to help you prepare your federal income tax return.

     Invesco 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 adviser for information concerning their individual situation.

How to withdraw from the Plan

You may withdraw from the plan at any time by calling 800 341 2929, visiting invesco.com or by writing to Invesco Closed-End Funds, Computershare Trust Company, N.A., P.O. Box 43078, Providence, RI 02940-3078. Simply indicate that you would like to withdraw from the Plan, and be sure to include your Trust name and account number. Also, ensure that all shareholders listed on the account have signed these written instructions. If you withdraw, you have three options with regard to the shares held in the Plan:

1. If you opt to continue to hold your non-certificated shares, whole shares will be held by the Agent and fractional shares will be sold. The proceeds will be sent via check to your address of record after deducting per share fees. Per share fees include any applicable brokerage commissions the Agent is required to pay.

2.

If you opt to sell your shares through the Agent, we will sell all full and fractional shares and send the proceeds via check to your address of record after deducting per share fees. Per share fees include any applicable brokerage commissions the Agent is required to pay.

3.

You may sell your shares through your financial adviser through the Direct Registration System (DRS). DRS is a service within the securities industry that allows Trust shares to be held in your name in electronic format. You retain full ownership of your shares, without having to hold a stock certificate. You should contact your financial adviser to learn more about any restrictions or fees that may apply.

     To obtain a complete copy of the Dividend Reinvestment Plan, please call our Client Services department at 800 341 2929 or visit invesco.com.

NOTE 1—Significant Accounting Policies

Invesco Municipal Income Opportunities Trust III, (“the Fund”), is a Massachusetts business trust registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, closed-end series management investment company, authorized to issue a limited number of common shares. Effective June 1, 2010, the Fund name changed from Morgan Stanley Municipal Income Opportunities Trust III to Invesco Municipal Income Opportunities Trust III.

  The Fund’s investment objective is to provide current income exempt from federal income tax.

  The following is a summary of the significant accounting policies followed by the Fund in the preparation of its financial statements.

A.	Security Valuations — Securities, including restricted securities, are valued according to the following policy.
	Securities are fair valued using an evaluated quote provided by an independent pricing service approved by the Board of Trustees. Evaluated quotes provided by the pricing service may be determined without exclusive reliance on quoted prices and may reflect appropriate factors such as institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, individual trading characteristics and other market data. Short-term obligations, including commercial paper, having 60 days or less to maturity are recorded at amortized cost which approximates value. Securities with a demand feature exercisable within one to seven days are valued at par. Debt securities are subject to interest rate and credit risks. In addition, all debt securities involve some risk of default with respect to interest and principal payments.
	Securities for which market quotations either are not readily available or are unreliable are valued at fair value as determined in good faith by or under the supervision of the Trust’s officers following procedures approved by the Board of Trustees. Some of the factors which may be considered in determining fair value are fundamental analytical data relating to the investment; the nature and duration of any restrictions on transferability or disposition; trading in similar securities by the same issuer or comparable companies; relevant political, economic or issuer specific news; and other relevant factors under the circumstances.
	Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer’s assets, general economic conditions, interest rates, investor perceptions and market liquidity. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.
B.	Securities Transactions and Investment Income — Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income is recorded on the accrual basis from settlement date. Dividend income (net of withholding tax, if any) is recorded on the ex-dividend date. Bond premiums and discounts are amortized and/or accreted for financial reporting purposes.
	The Fund may periodically participate in litigation related to Fund investments. As such, the Fund may receive proceeds from litigation settlements. Any proceeds received are included in the Statement of Operations as realized gain (loss) for investments no longer held and as unrealized gain (loss) for investments still held.
	Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of realized and unrealized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the realized and unrealized net gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund’s net asset value and, accordingly, they

14        Invesco Municipal Income Opportunities Trust III

	reduce the Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and Statement of Changes in Net Assets, or the net investment income per share and ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the investment adviser.
	The Fund allocates realized and unrealized capital gains and losses to a class based on the relative net assets of each class. The Fund allocates income to a class based on the relative value of the settled shares of each class.
C.	Country Determination — For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.
D.	Distributions — Dividends and distributions to shareholders are recorded on the ex-dividend date
E.	Federal Income Taxes — The Fund intends to comply with the requirements of Subchapter M of the Internal Revenue Code necessary to qualify as a regulated investment company and to distribute substantially all of the Fund’s taxable earnings to shareholders. As such, the Fund will not be subject to federal income taxes on otherwise taxable income (including net realized capital gain) that is distributed to shareholders. Therefore, no provision for federal income taxes is recorded in the financial statements.
	The Fund files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally the Fund is subject to examinations by such taxing authorities for up to three years after the filing of the return for the tax period.
F.	Accounting Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period including estimates and assumptions related to taxation. Actual results could differ from those estimates by a significant amount. In addition, the Fund monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are released to print.
G.	Indemnifications — Under the Fund’s organizational documents, each Trustee, officer, employee or other agent of the Trust is indemnified against certain liabilities that may arise out of performance of their duties to the Fund. Additionally, in the normal course of business, the Fund enters into contracts, including the Fund’s servicing agreements that contain a variety of indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.
H.	Floating Rate Obligations Related to Securities Held — The Fund enters into transactions in which it transfers to Special Purpose Trusts established by a Broker Dealer (“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 Fund to retain residual interest in the bonds. The Fund may enter into shortfall agreements with the Dealer Trusts which commit the Fund 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 Fund (inverse floating rate investments) include the right of the Fund (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 Fund, thereby collapsing the Dealer Trusts. The Fund accounts for the transfer of bonds to the Dealer Trusts as secured borrowings, with the securities transferred remaining in the Fund’s investment assets, and the related floating rate notes reflected as Fund liabilities under the caption “Floating rate note and dealer trust obligations” on the Statement of Assets and Liabilities. The Fund 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” on the 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. The average floating rate notes outstanding and average annual interest and fee rate related to residual interests during the six months ended September 30, 2010 were $4,075,000 and 1.40%, respectively.

NOTE 2—Advisory Fees and Other Fees Paid to Affiliates

Effective June 1, 2010, the Fund has entered into a master investment advisory agreement with Invesco Advisers, Inc. (the “Adviser” or “Invesco”). Under the terms of the investment advisory agreement, the Fund pays an advisory fee to the Adviser based on the annual rate 0.50% of the Fund’s average weekly net assets. Prior June 1, 2010, the Fund paid an advisory fee of $57,204 to Morgan Stanley Investment Advisors Inc. (“MSIA”) based on the annual rate above of the Fund’s average weekly net assets.

  Effective June 1, 2010, under the terms of a master sub-advisory agreement between the Adviser and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Australia Limited, Invesco Hong Kong Limited, Invesco Senior Secured Management, Inc. and Invesco Trimark Ltd. (collectively, the “Affiliated Sub-Advisers”) the Adviser, not the Fund, may pay 40% of the fees paid to the Adviser to any such Affiliated Sub-Adviser(s) that provide discretionary investment management services to the Fund based on the percentage of assets allocated to such Sub-Adviser(s).

  Effective June 1, 2010, the Adviser has contractually agreed, through at least June 30, 2012, to waive advisory fees and/or reimburse expenses to the extent necessary to limit the Fund’s expenses (excluding certain items discussed below) to 0.84%. In determining the Adviser’s obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Fund’s expenses to exceed the limit reflected above: (1) interest; (2) taxes; (3) dividend expense on short sales; (4) extraordinary or non-routine items; and (5) expenses that the Fund has incurred but did not actually pay

15        Invesco Municipal Income Opportunities Trust III

because of an expense offset arrangement. Unless the Board of Trustees and Invesco mutually agree to amend or continue the fee waiver agreement, it will terminate on June 30, 2012. The Adviser did not waive fees and/or reimburse expenses during the period under this expense limitation.

  Prior June 1, 2010, investment advisory fees paid by the Fund were reduced by an amount equal to the advisory and administrative service fees paid by Morgan Stanley Institutional Liquidity Funds — Tax Exempt Portfolio — Institutional Class shares.

  For the six months ended September 30, 2010, the Adviser and MSIA did not waive advisory fees.

  The Fund has entered into a master administrative services agreement with Invesco pursuant to which the Fund has agreed to pay Invesco for certain administrative costs incurred in providing accounting services to the Fund. Prior June 1, 2010, the Fund paid an administration fee of $25,865 to Morgan Stanley Services Company Inc. For the six months ended September 30, 2010, expenses incurred under these agreements are shown in the Statement of Operations as administrative services fees.

  Also, Invesco has entered into service agreements whereby State Street Bank and Trust Company (“SSB”) serves as the custodian, fund accountant and provides certain administrative services to the Fund.

  Certain officers and trustees of the Fund are officers and directors of Invesco and/or IDI.

NOTE 3—Additional Valuation Information

GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3) generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1 —	Prices are determined using quoted prices in an active market for identical assets.
Level 2 —	Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
Level 3 —	Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

  The following is a summary of the tiered valuation input levels, as of September 30, 2010. The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

  During the six months ended September 30, 2010, there were no significant transfers between investment levels.

	Level 1		Level 2		Level 3		Total
Municipal Obligations	$	—	$	73,178,301	$	—	$	73,178,301
Short-term Investments		—		1,050,000		—		1,050,000
	$	—	$	74,228,301	$	—	$	74,228,301

NOTE 4—Trustees’ and Officers’ Fees and Benefits

“Trustees’ and Officers’ Fees and Benefits” include amounts accrued by the Fund to pay remuneration to certain Trustees and Officers of the Fund. Trustees have the option to defer compensation payable by the Fund, and “Trustees’ and Officers’ Fees and Benefits” also include amounts accrued by the Fund to fund such deferred compensation amounts. Those Trustees who defer compensation have the option to select various Invesco Funds in which their deferral accounts shall be deemed to be invested. Finally, certain current Trustees are eligible to participate in a retirement plan that provides for benefits to be paid upon retirement to Trustees over a period of time based on the number of years of service. The Fund may have certain former Trustees who also participate in a retirement plan and receive benefits under such plan. “Trustees’ and Officers’ Fees and Benefits” include amounts accrued by the Fund to fund such retirement benefits. Obligations under the deferred compensation and retirement plans represent unsecured claims against the general assets of the Fund.

NOTE 5—Cash Balances

The Fund is permitted to temporarily carry a negative or overdrawn balance in its account with SSB, the custodian bank. To compensate the custodian bank for such overdrafts, the overdrawn Fund may either (1) leave funds as a compensating balance in the account so the custodian bank can be compensated by earning the additional interest; or (2) compensate by paying the custodian bank at a rate agreed upon by the custodian bank and Invesco, not to exceed the contractually agreed upon rate.

NOTE 6—Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Reclassifications are made to the Fund’s capital accounts to reflect income and gains available for distribution (or available

16        Invesco Municipal Income Opportunities Trust III

capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at the Fund’s fiscal year-end.

  Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Fund to utilize. The ability to utilize capital loss carryforward in the future may be limited under the Internal Revenue Code and related regulations based on the results of future transactions.

  The Fund had a capital loss carryforward as of March 31, 2010 which expires as follows:

	Capital Loss
Expiration	Carryforward*
March 31, 2013	$	482,196
March 31, 2016		623,926
March 31, 2017		2,683,451
March 31, 2018		2,620,151
Total capital loss carryforward	$	6,409,724

*  Capital loss carryforward as of the date listed above is reduced for limitations, if any, to the extent required by the Internal Revenue Code.

NOTE 7—Investment Securities

The aggregate amount of investment securities (other than short-term securities, U.S. Treasury obligations and money market funds, if any) purchased and sold by the Fund during the six months ended September 30, 2010 was $7,555,305 and $8,393,964 respectively. Cost of investments on a tax basis includes the adjustments for financial reporting purposes as of the most recently completed Federal income tax reporting period-end.

  The Trustees have approved share repurchases whereby the Fund 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.

NOTE 10—Purposes of and Risks Relating to Certain Financial Instruments

The Fund may invest a portion of its assets in inverse floating rate municipal securities, which are variable debt instruments that pay interest at rates that move in the opposite direction of prevailing interest rates. These investments are typically used by the Fund in seeking to enhance the yield of the portfolio. Inverse floating rate investments tend to underperform the market for fixed rate bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Inverse floating rate investments have varying degrees of liquidity. Inverse floating rate securities in which the Fund may invest include derivative instruments such as residual interest bonds (“RIBs”) or tender option bonds (“TOBs”). Such instruments are typically created by a special purpose trust that holds long-term fixed rate bonds (which may be tendered by the Fund in certain instances) and sells two classes of beneficial interests: short-term floating rate interests, which are sold to third party investors, and inverse floating residual interests, which are

17        Invesco Municipal Income Opportunities Trust III

purchased by the Fund. The short-term floating rate interests have first priority on the cash flow from the bonds held by the special purpose trust and the Fund is paid the residual cash flow from the bonds held by the special purpose trust.

  The Fund generally invests in inverse floating rate investments that include embedded leverage, thus exposing the Fund to greater risks and increased costs. The market value of a “leveraged” inverse floating rate investment generally will fluctuate in response to changes in market rates of interest to a greater extent than the value of an unleveraged investment. The extent of increases and decreases in the value of inverse floating rate investments generally will be larger than changes in an equal principal amount of a fixed rate security having similar credit quality, redemption provisions and maturity, which may cause the Fund’s net asset value to be more volatile than if it had not invested in inverse floating rate investments.

  In certain instances, the short-term floating rate interests created by the special purpose trust may not be able to be sold to third parties or, in the case of holders tendering (or putting) such interests for repayment of principal, may not be able to be remarketed to third parties. In such cases, the special purpose trust holding the long-term fixed rate bonds may be collapsed. In the case of RIBs or TOBs created by the contribution of long-term fixed income bonds by the Fund, the Fund will then be required to repay the principal amount of the tendered securities. During times of market volatility, illiquidity or uncertainty, the Fund could be required to sell other portfolio holdings at a disadvantageous time to raise cash to meet that obligation.

  The Fund may also invest in private placement securities. TOBs are presently classified as private placement securities. Private placement securities are subject to restrictions on resale because they have not been registered under the Securities Act of 1933, as amended or are otherwise not readily marketable. As a result of the absence of a public trading market for these securities, they may be less liquid than publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the Fund or less than what may be considered the fair value of such securities.

NOTE 12—Change in Independent Registered Public Accounting Firm

The Audit Committee of the Board of Trustees of the Fund appointed, and the Board of Trustees ratified and approved, PricewaterhouseCoopers LLP (“PWC”) as the independent registered public accounting firm of the Fund for the fiscal year following May 31, 2010. Prior to May 31, 2010, the Fund was audited by a different independent registered public accounting firm (the “Prior Auditor”). The Board of Trustees selected a new independent auditor for the Fund’s current fiscal year in connection with the appointment of Invesco Advisers as investment adviser to the Fund (“New Advisory Agreement”).

  Effective June 1, 2010, the Prior Auditor resigned as the independent registered public accounting firm of Fund. The Prior Auditor’s report on the financial statements of the Fund for the past two years did not contain an adverse or disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope or accounting principles. During the period the Prior Auditor was engaged, there were no disagreements with the Prior Auditor on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to the Prior Auditor’s satisfaction, would have caused it to make reference to that matter in connection with its report.

19        Invesco Municipal Income Opportunities Trust III

Approval of Investment Advisory and Sub-advisory Agreements

The Board of Trustees (the Board) of Invesco Municipal Income Opportunities Trust III (the Trust) is required under the Investment Company Act of 1940 to approve the Trust’s investment advisory agreements. At various meetings of the Board held during the third and fourth quarters of 2009 and early 2010, the Board as a whole and the disinterested or “independent” Trustees, voting separately, approved (i) a new investment advisory agreement with Invesco Advisers, Inc. (Invesco Advisers), (ii) a new Master Sub-Advisory Agreement (the sub-advisory agreement and, together with the investment advisory agreement with Invesco Advisers, the new advisory agreements) with Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Australia Limited, Invesco Hong Kong Limited, Invesco Senior Secured Management, Inc. and Invesco Trimark Ltd. (collectively, the Affiliated Sub-Advisers), and (iii) the appointment of Invesco Advisers as investment adviser and the Affiliated Sub-Advisers as investment sub-advisers to the Trust. In doing so, the Board determined that the new advisory agreements will enable shareholders of the Trust to obtain high quality services at a cost that is appropriate, reasonable and in the best interests of the Trust and its shareholders and that the compensation to Invesco Advisers and the Affiliated Sub-Advisers under the Trust’s new advisory agreements is fair and reasonable. The new advisory agreements were approved to become effective upon approval by the shareholders of the Trust and closing of a transaction (the Transaction) between Morgan Stanley and Invesco Ltd. (Invesco) under which Invesco acquired the retail mutual fund assets of Morgan Stanley (the Acquisition).

The Board’s Trust Evaluation Process

In reaching their decision, the Board requested and obtained information from Morgan Stanley, Invesco Advisers and Invesco, including information obtained during various meetings with Senior Management at Invesco, as they deemed reasonably necessary to evaluate the new advisory agreements for the Trust. In considering the Trust’s new advisory agreements, the Board evaluated a number of factors and considerations listed below that they believed, in light of their own business judgment, to be relevant to their determination.

  1. The Board considered the reputation, financial strength and resources of Invesco, one of the world’s leading independent global investment management firms, the strength of Invesco’s resources and investment capabilities and the client-focused shareholder services offered by Invesco.

  2. The Board discussed the challenges of positioning the Trust on a common operating platform with Invesco, with particular emphasis on ensuring portfolio management operations properly migrate to Invesco as part of the Acquisition, to ensure uninterrupted services for shareholders and the opportunity for the portfolio management of the Trust to recognize savings from economies of scale when such savings occur.

  3. The Board noted the continuity of key investment management personnel that would manage the Trust upon consummation of the Acquisition, specifically noting that, the persons responsible for the portfolio management of the Trust are expected to remain the same.

  4. The Board noted that entering into the sub-advisory agreement would provide Invesco Advisers with increased flexibility in assigning portfolio managers to the Trust and would give the Trust access to portfolio managers and investment personnel located in other offices, including those outside the United States, who may have more specialized expertise on local companies, markets and economies or on various types of investments and investment techniques.

  5. The Board noted that, pursuant to the sub-advisory agreement, Invesco Advisers would pay all of the sub-advisory fees of the Affiliated Sub-Advisers out of its management fees.

  6. The Board noted the undertaking by Invesco and Morgan Stanley or their respective affiliates to assume all of the costs of the Acquisition, including the cost of obtaining the shareholder approvals discussed above. The Board noted that Invesco Advisers would provide a two-year contractual guaranty to limit the total expense ratio of the Trust to the Trust’s total expense ratio prior to the Acquisition. In determining the obligation to waive advisory fees and/or reimburse expenses, the following is not taken into account: (i) interest, (ii) taxes, (iii) dividend expense on short sales, (iv) extraordinary or non-routine items, and (v) expenses that the Trust has incurred but did not actually pay because of an offset arrangement. During the Board’s extensive review process, the Board, including the independent Trustees, considered, among other things, the following factors: the terms and conditions of the new advisory agreements, including the differences from the advisory agreement with Morgan Stanley affiliates; and the nature, scope and quality of services that Invesco Advisers and its affiliates are expected to provide to the Trust, including sub-advisory services and compliance services. The Board evaluated all information available to them on a trust-by-trust basis, and their determinations were made separately in respect of the Trust. The Board also based their decisions on the following considerations, among others, although they did not identify any consideration that was all important or controlling of their discussions, and each Trustee attributed different weights to the various factors.

A.  Nature, Extent and Quality of Services.

The Board reviewed and considered the nature and extent of the investment advisory services to be provided by Invesco Advisers and the Affiliated Sub-Advisers under the new advisory agreements, 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 to be provided by Invesco Advisers under the Trust’s administration agreement, including accounting services and the provision of supplies, office space and utilities at Invesco Advisers’ expense. The Board was advised that there was no expected diminution in the nature, quality and extent of services provided to the Trust’s shareholders.

  The Board reviewed and considered the qualifications of the portfolio managers who are expected to continue as portfolio managers, noting the one portfolio manager who would not continue to manage the Trust as a result of the new advisory agreements, and the senior administrative managers and other key personnel of Invesco Advisers or its affiliates who will provide the advisory and administrative services to the Trust.

B.  Performance, Fees and Expenses of the Trust.

The Board noted that Invesco Advisers and the Affiliated Sub-Advisers had not yet begun providing services to the Trust and, therefore, concluded that performance was not a factor they needed to address with respect to the approval of the new advisory agreements. They also considered that management fees would not increase under the new advisory agreements and that Invesco Advisers would pay the fee under the sub-advisory agreement out of its management fees. Furthermore, the Board considered that Invesco Advisers would provide a two-year contractual guaranty to limit the total expense ratio of the Trust to the Trust’s total expense ratio prior to the Acquisition.

C.  Economies of Scale.

The Board considered the benefits that the shareholders of the Trust would be afforded as a result of anticipated economies of scale.

D.  Other Benefits of the Relationship.

The Board considered other benefits to Invesco Advisers and its affiliates that may be derived from their relationship with the Trust and other funds advised by Invesco Advisers.

E.  Resources of the Adviser.

The Board considered whether Invesco Advisers and the Affiliated Sub-Advisers were financially sound and had the resources necessary to perform their obligations under the new advisory agreements, noting assurances that Invesco Advisers and the Affiliated Sub-Advisers had the financial resources necessary to fulfill their obligations under the new advisory agreements and the benefits to the Trust of such a relationship.

F.  General Conclusion.

After considering and weighing all of the above factors, the Board, including the independent Trustees, unanimously concluded that it would be in the best interest of the Trust and its shareholders to approve the new advisory agreements with respect to the Trust. In reaching this conclusion, the Board did not give particular weight to any single factor referenced above. The Board considered these factors over the course of numerous meetings, some of which were in executive session with only the independent Trustees and their counsel present.
