Letters to Shareholders

Philip Taylor

Dear Shareholders:

Enclosed is important information about your Fund and its performance.

     I’ve always believed that companies have an obligation to communicate regularly with their clients, and I believe that obligation is especially critical in the investment industry.

     Our website – invesco.com/us – offers timely market updates and commentary from many of our portfolio managers and other investment professionals, as well as quarterly messages from me. At invesco.com/us, you also can obtain information about your account at any hour of the day or night. I invite you to visit and explore the tools and information we offer.

Invesco’s commitment to investment excellence

As a strong organization with a single focus – investment management – Invesco today offers investment capabilities to meet the needs of virtually any investor.

     Investment excellence is our goal. Let me explain what that means. All of our funds are managed by specialized teams of investment professionals. Each team has a discrete investment perspective and philosophy, and all follow disciplined, repeatable processes governed by strong risk oversight. Our investment-centric culture provides an environment that seeks to reduce distractions, allowing our fund managers to concentrate on what they do best – manage your money.

     The importance of investment management expertise is obvious given the markets we’ve experienced over the last two to three years. We’ve seen that investment strategies can outperform or underperform their benchmark indexes for a variety of reasons, including where we are in the market cycle, and whether prevailing economic conditions are favorable or unfavorable for that strategy. That’s why no investment strategy can guarantee top-tier performance at all times. What investors can expect, and what Invesco offers, are funds that are managed according to their stated investment objectives and strategies, with robust risk oversight using consistent, repeatable investment processes that don’t change as short-term external conditions change – investments managed for the long term. This disciplined approach can’t guarantee a profit; no investment can do that, since all involve some measure of risk. But it can ensure that your money is managed the way we said it would be.

     This adherence to stated investment objectives and strategies allows your financial advisor to build a diversified portfolio that meets your individual risk tolerance and financial goals. It also means that when your goals change, your financial advisor will be able to find an appropriate investment option to meet your needs.

Invesco’s commitment to you

Invesco’s commitment to you remains stronger than ever. It’s one of the reasons we’ve grown to become one of the world’s largest asset managers.

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

     I want to thank you for placing your trust in us. All of us at Invesco look forward to serving your investment management needs for many years to come. Thank you for investing with us.

Sincerely,

Philip Taylor
Senior Managing Director, Invesco Ltd.

Bruce Crockett

Dear Fellow Shareholders:

With 2010 behind us, now is a good time to review our portfolios and ensure that we are adhering to a long-term, diversified investment strategy, which I’ve mentioned in previous letters. The year was notable for a number of reasons, but I’m sure most of us are grateful for a return to more stable markets and growing signs that the worst of the economic crisis is behind us.

     Your Board continued to oversee the Invesco Funds with a strong sense of responsibility for your savings and a deep appreciation for your continued trust. As always, we worked throughout 2010 to manage costs and ensure Invesco continued to place investor interests first.

     I’m pleased to report that the latest report from Morningstar affirmed the work we’ve done and included a number of positive comments regarding your Board’s oversight of the Invesco Funds. As background, Morningstar is a leading independent provider of investment research in North America, Europe, Australia and Asia. Morningstar stated, “A fund board’s duty is to represent the interests of fund shareholders, ensuring that the funds that it oversees charge reasonable fees and are run by capable advisors with a sound investment process.” Morningstar maintained your Fund Board’s “A” grade for Board Quality, praising the Board for taking “meaningful steps in recent years to act in fund shareholders’ interests.”¹ These steps included becoming much more proactive and vocal in overseeing how Invesco votes the funds’ shareholders’ proxies and requiring each fund trustee to invest more than one year’s board compensation in Invesco funds, further aligning our interests with those of our shareholders. Morningstar also cited the work I’ve done to make myself more available to fund shareholders via email.

     I am also pleased that Morningstar recognized the effort and the Fund Board’s efforts over the past several years to work together with management at Invesco to enhance performance and sharpen the focus on investors.

     Let me close by wishing you a happy and prosperous new year. As always, you’re welcome to contact me at bruce@brucecrockett.com with any questions or concerns you have. We look forward to representing you and serving you in the new year.

Sincerely,

Bruce L. Crockett
Independent Chair
Invesco Funds Board of Trustees

1 Among the criteria Morningstar considers when evaluating a fund board are the degree to which the board is independent of the fund company; board members’ financial interests are aligned with those of fund shareholders; the board acts in fund shareholders’ interests; and the board works constructively with company management and investment personnel. Morningstar first awarded an “A” rating to the Invesco Funds board on September 13, 2007; that rating has been maintained in subsequent reports, the most recent of which was released December 17, 2010. Ratings are subject to change, usually every 12 to 24 months. Morningstar ratings range from “A” to “F.”

Management’s Discussion of Trust Performance

Performance summary

Please note that the fiscal year-end for Invesco Insured Municipal Securities has changed to February 28. Therefore, the period covered by this report is from October 31, 2010, the date of the last annual report, through February 28, 2011, the Trust’s new fiscal year-end.

     The Trust’s return can be calculated based on either the market price or the net asset value (NAV) of its shares. NAV per share is determined by dividing the value of the Trust’s portfolio securities, cash and other assets, less all liabilities, by the total number of common shares outstanding. Market price reflects the supply and demand for Trust shares. As a result, the two returns can differ, as they did during the reporting period. A main contributor to the Trust’s return on an NAV basis was its exposure to transportation bonds.

Performance

Cumulative total returns, 10/31/10 to 2/28/11

Trust at NAV	-4.29	%
Trust at Market Value	-8.16
Market Price Discount to NAV as of 2/28/11	-7.32

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 Trust 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 Trust is a closed-end management investment company, shares of the Trust 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 Trust cannot predict whether shares will trade at, above or below NAV. The Trust should not be viewed as a vehicle for trading purposes. It is designed primarily for risk-tolerant long-term investors.

How we invest

We seek to provide investors with current income exempt from federal income tax, primarily by investing in a diversified portfolio of municipal securities that are covered by insurance with respect to timely payment of principal and interest.

     We seek to achieve the Trust’s investment objective by investing primarily in insured municipal obligations that are rated A or higher by at least one nationally recognized statistical rating organization. Municipal obligations include municipal bonds, municipal notes, municipal commercial paper and lease obligations. The Trust may invest in

taxable or tax-exempt investment grade securities, or if not rated, securities we determine to be of comparable quality. From time to time, we may invest in municipal securities that pay interest that is subject to the federal alternative minimum tax.

     We employ a bottom-up, research-driven approach to identify securities that have attractive risk/reward characteristics for the sectors in which we invest. We also integrate macroeconomic analysis and forecasting into our evaluation and ranking of various sectors and individual securities.

Market conditions and your Trust

In the U.S. and most of the developed world, a gradual and somewhat lackluster recovery continued, with central banks keeping interest rates at low levels and with few of them withdrawing their quantitative easing measures. This helped private sector companies improve their balance sheets and earnings following the global financial crisis that began to dissipate in early 2009. However, investor skepticism of global governments’ abilities to retire huge amounts of debt without affecting economic growth rates caused sovereign debt distress (especially for eurozone countries) and became a focal point of investor concern.

     In the U.S., economic recovery was present, although the pace was modest as stubbornly high unemployment and export weakness continued to weigh on the economy. Real gross domestic product (GDP), the broadest measure of overall U.S. economic activity, increased at an annual rate of 3.1% in the fourth quarter of 2010, a marked improvement from the 2.6% decrease in 2009.¹ The U.S. Federal Reserve (the Fed) maintained a very accommodative monetary policy throughout the period, with the federal funds target rate unchanged in a range of zero to 0.25%.² The Fed recently described its view of the U.S. economy by stating: “The Committee will maintain the target range for the federal funds rate at 0 to ¹/4 percent and continues to anticipate that economic conditions, including low rates of resource utilization, subdued inflation trends, and stable inflation expectations, are likely to warrant exceptionally low levels for the federal funds rate for an extended period.”²

4 Invesco Insured Municipal Securities

     During the four-month period covered by this report, municipal bond mutual funds experienced extensive net outflows. Market volatility was heightened across the municipal asset class as U.S. Treasury yields increased and the market was flooded with new issuance during the last two months of 2010 in anticipation of the Build America Bond (BAB) program ending. These factors contributed to rising investor fears regarding the health of municipal finances, leading to redemptions and lower municipal bond prices.

     The Trust’s exposure to the 15- to 20-year portion of the yield curve detracted from returns as yields increased during most of the reporting period. Some of our yield curve and duration positioning was obtained through the use of inverse floating rate securities. Inverse floating rate securities are instruments which have an inverse relationship to a referenced interest rate. Inverse floating rate securities can be a more efficient way to manage duration, yield curve exposure and credit exposure and potentially can enhance yield.

     Sector performance was driven by quality spread widening for most of the reporting period before tightening in February, largely due to increased volatility and higher tax-exempt issuance. As a result, BBB-rated and lower credit quality sectors underperformed and detracted from Trust performance as we held exposure to these market segments.

     Our exposure to transportation bonds and dedicated tax bonds contributed to returns for the reporting period. Our exposure to health care and industrial development revenue/pollution control revenue bonds detracted from returns.

     As stated earlier, the Trust trades at a market price and also has an NAV. For the four-month reporting period, the Trust traded at a discount to its NAV.

     Thank you for investing in Invesco Insured Municipal Securities and for sharing our long-term investment horizon.

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/us.
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 enroll in the Plan by visiting invesco.com/us, calling toll-free 800 341 2929 or notifying us in writing at Invesco Closed-End Funds, Computershare Trust 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 10 business days 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/us 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.

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 Trust may periodically participate in litigation related to Trust investments. As such, the Trust 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.

16        Invesco Insured Municipal Securities

	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 net realized and unrealized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the net realized and unrealized gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Trust’s net asset value and, accordingly, they reduce the Trust’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 Trust and the investment adviser.
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 — The Trust declares and pays monthly dividends from net investment income. Distributions from net realized capital gain, if any, are generally paid annually. The Trust may elect to treat a portion of the proceeds from redemptions as distributions for federal income tax purposes.
E.	Federal Income Taxes — The Trust 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 Trust’s taxable earnings to shareholders. As such, the Trust 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.
	In addition, the Trust intends to invest in such municipal securities to allow it to qualify to pay shareholders “exempt-interest dividends”, as defined in the Internal Revenue Code.
	The Trust files tax returns in the U.S. Federal jurisdiction and certain other jurisdictions. Generally the Trust 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 Trust 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 Trust’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 Trust. Additionally, in the normal course of business, the Trust enters into contracts, including the Trust’s servicing agreements that contain a variety of indemnification clauses. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. The risk of material loss as a result of such indemnification claims is considered remote.
H.	Floating Rate Note Obligations — The Trust invests in inverse floating rate securities, such as Residual Interest Bonds (“RIBs”) or Tender Option Bonds (“TOBs”) for investment purposes and to enhance the yield of the Trust. 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. Such transactions may be purchased in the secondary market without first owning the underlying bond or by the sale of fixed rate bonds by the Trust to special purpose trusts established by a broker dealer (“Dealer Trusts”) in exchange for cash and residual interests in the Dealer Trusts’ assets and cash flows, which are in the form of inverse floating rate securities. The Dealer Trusts finance 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 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 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.
	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 Trust or less than what may be considered the fair value of such securities.
	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 as a component of Interest, facilities and maintenance fees on the Statement of Operations.
	The Trust generally invest in inverse floating rate securities that include embedded leverage, thus exposing the Trust to greater risks and increased costs. The primary risks associated with inverse floating rate securities are varying degrees of liquidity and the changes in the value of such securities in response to changes in market rates of interest to a greater extent than the value of an equal principal amount of a fixed rate security having similar credit quality, redemption provisions and maturity which may cause the Trust’s net asset value to be more volatile than if it had not invested in inverse floating rate securities. 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

17        Invesco Insured Municipal Securities

	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 Trust, the Trust will then be required to repay the principal amount of the tendered securities. During times of market volatility, illiquidity or uncertainty, the Trust could be required to sell other portfolio holdings at a disadvantageous time to raise cash to meet that obligation.
I.	Futures Contracts — The Fund may enter into futures contracts to manage exposure to interest rate, equity and market price movements and/or currency risks. A futures contract is an agreement between two parties to purchase or sell a specified underlying security, currency or commodity (or delivery of a cash settlement price, in the case of an index future) for a fixed price at a future date. The Fund currently invests only in exchange-traded futures and they are standardized as to maturity date and underlying financial instrument. Initial margin deposits required upon entering into futures contracts are satisfied by the segregation of specific securities or cash as collateral at the futures commission merchant (broker). During the period the futures contracts are open, changes in the value of the contracts are recognized as unrealized gains or losses by recalculating the value of the contracts on a daily basis. Subsequent or variation margin payments are received or made depending upon whether unrealized gains or losses are incurred. These amounts are reflected as receivables or payables on the Statement of Assets and Liabilities. When the contracts are closed or expire, the Fund recognizes a realized gain or loss equal to the difference between the proceeds from, or cost of, the closing transaction and the Fund’s basis in the contract. The net realized gain (loss) and the change in unrealized gain (loss) on futures contracts held during the period is included on the Statement of Operations. The primary risks associated with futures contracts are market risk and the absence of a liquid secondary market. If the Fund were unable to liquidate a futures contract and/or enter into an offsetting closing transaction, the Fund would continue to be subject to market risk with respect to the value of the contracts and continue to be required to maintain the margin deposits on the futures contracts. Futures contracts have minimal counterparty risk since the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees the futures against default. Risks may exceed amounts recognized in the Statement of Assets and Liabilities.
J.	Other Risks — The value of, payment of interest on, repayment of principal for and the ability to sell a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives and the economics of the regions in which the issuers are located.
	Since, many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market and a Trust’s investments in municipal securities.
	There is some risk that a portion or all of the interest received from certain tax-free municipal securities could become taxable as a result of determinations by the Internal Revenue Service.
K.	Interest, Facilities and Maintenance Fees — Interest, Facilities and Maintenance Fees include interest and related borrowing costs such as commitment fees and other expenses associated with lines of credit and interest and administrative expenses related to establishing and maintaining floating rate note obligations, if any.

NOTE 2—Advisory Fees and Other Fees Paid to Affiliates

The Trust 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 Trust pays an advisory fee to the Adviser based on the annual rate 0.27% of the Trust’s average weekly net assets. Prior to June 1, 2010, the Trust paid an advisory fee of $148,164 to Morgan Stanley Investment Advisors Inc. (“MSIA”) based on the annual rate and Trust’s average weekly net assets as discussed above.

  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 Trust, 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 Trust based on the percentage of assets allocated to such Sub-Adviser(s).

  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 total annual Trust operating expenses after fee waiver and/or expense reimbursement (excluding certain items discussed below) to 0.54%. 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 Trust’s expenses to exceed the limit reflected above: (1) interest, facilities and maintenance fees (2) taxes; (3) dividend expense on short sales; (4) extraordinary or non-routine items; and (5) expenses that the Trust has incurred but did not actually pay 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 to June 1, 2010, investment advisory fees paid by the Trust were reduced by an amount equal to the advisory and administrative services fees paid by Morgan Stanley Institutional Liquidity funds — Tax Exempt Portfolio — Institutional Class shares.

  For the period November 1, 2010 to February 28, 2011 and the year ended October 31, 2010, the Adviser and MSIA waived advisory fees of $0 and $7,210, respectively.

  The Trust has entered into a master administrative services agreement with Invesco pursuant to which the Trust has agreed to pay Invesco for certain administrative costs incurred in providing accounting services to the Trust. Prior to June 1, 2010, the Trust paid an administration fee of $43,692 to Morgan Stanley Services Company, Inc. For the period November 1, 2010 to February 28, 2011 and the year ended October 31, 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 and fund accountant and provides certain administrative services to the Trust.

  Certain officers and trustees of the Trust are officers and directors of Invesco.

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 Trust’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 February 28, 2011. 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 period November 1, 2010 to February 28, 2011, there were no significant transfers between investment levels.

	Level 1		Level 2		Level 3		Total
Municipal Obligations	$	—	$	94,459,062	$	—	$	94,459,062

NOTE 4—Derivative Investments

The Trust has implemented the required disclosures about derivative instruments and hedging activities in accordance with GAAP. This disclosure is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entity’s financial position and financial performance. The enhanced disclosure has no impact on the results of operations reported in the financial statements.

Effect of Derivative Instruments for the Period November 1, 2010 to February 28, 2011 and the year ended October 31, 2010

The table below summarizes the gains (losses) on derivative instruments, detailed by primary risk exposure, recognized in earnings during the period:

	Location of Gain (Loss) on Statement of Operations
	Futures

Realized Gain
Interest rate risk	$	—	$	375,035
Change in Unrealized Appreciation (Depreciation)
Interest rate risk		—		(144,842	)
Total	$	—	$	230,193

*  The average notional value of futures during the year ended October 31, 2010 was $3,200,836.

NOTE 5—Trustees’ and Officers’ Fees and Benefits

“Trustees’ and Officers’ Fees and Benefits” include amounts accrued by the Trust to pay remuneration to certain Trustees and Officers of the Trust. Trustees have the option to defer compensation payable by the Trust, and “Trustees’ and Officers’ Fees and Benefits” also include amounts accrued by the Trust 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 Trust 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 Trust to fund such retirement benefits. Obligations under the deferred compensation and retirement plans represent unsecured claims against the general assets of the Trust.

  During the period November 1, 2010 to February 28, 2011 and the year ended October 31, 2010, the Trust paid legal fees of $577 and $62, respectively, for services rendered by Kramer, Levin, Naftalis & Frankel LLP as counsel to the Independent Trustees. A member of that firm is a Trustee of the Trust.

19        Invesco Insured Municipal Securities

NOTE 6—Cash Balances and Borrowings

The Trust 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 Trust 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.

  Inverse floating rate obligations resulting form the transfer of bonds to Dealer Trusts are accounted for as secured borrowings. The average floating rate notes outstanding and average annual interest and fees related to inverse floating rate note obligations during the period November 1, 2010 to February 28, 2011 and the year ended October 31, 2010 were $3,300,000 and 0.63% and $3,500,000 and 0.86%, respectively.

NOTE 7—Distributions to Shareholders and Tax Components of Net Assets

Tax Character of Distributions to Shareholders Paid During the Period November 1, 2010 to February 28, 2011 and the Years Ended October 31, 2010 and 2009:

	2011		2010		2009
Tax-exempt income	$	1,252,363	$	3,757,090	$	4,004,268
Ordinary income		—		97,644		37,685
Long-term capital gain		—		—		180,510
Total distributions	$	1,252,363	$	3,854,734	$	4,222,463

Tax Components of Net Assets at Period-End:

	2011
Undistributed ordinary income	$	440,719
Net unrealized appreciation (depreciation) — investments		(1,637,316	)
Temporary book/tax differences		(55,505	)
Capital loss carryforward		(2,734,888	)
Shares of beneficial interest		94,894,828
Total net assets	$	90,907,838

  The difference between book-basis and tax-basis unrealized appreciation (depreciation) is due to differences in the timing of recognition of gains and losses on investments for tax and book purposes. The Trust’s net unrealized appreciation (depreciation) difference is attributable primarily to bond premium amortization.

  The temporary book/tax differences are a result of timing differences between book and tax recognition of income and/or expenses. The Trust’s temporary book/tax differences are the result of the trustee deferral of compensation and retirement plan benefits.

  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 Trust 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 Trust has a capital loss carryforward as of February 28, 2011 which expires as follows:

	Capital Loss
Expiration	Carryforward*
February 28, 2017	$	2,611,249
February 28, 2019		123,639
Total capital loss carryforward	$	2,734,888

*  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 8—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 Trust during November 1, 2010 to February 28, 2011 was $5,307,415 and $4,408,900, 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.

Unrealized Appreciation (Depreciation) of Investment Securities on a Tax Basis
Aggregate unrealized appreciation of investment securities	$	1,137,376
Aggregate unrealized (depreciation) of investment securities		(2,774,692	)
Net unrealized appreciation (depreciation) of investment securities	$	(1,637,316	)
Cost of investments for tax purposes is $96,096,378.

20        Invesco Insured Municipal Securities

NOTE 9—Reclassification of Permanent Differences

Primarily as a result of differing book/tax treatment of excise taxes, on February 28, 2011, undistributed net investment income was decreased by $3,658, undistributed net realized gain (loss) was decreased by $29 and shares of beneficial interest increased by $3,687. This reclassification had no effect on the net assets of the Trust.

NOTE 10—Shares of Beneficial Interest

Transactions in shares of beneficial interest were as follows:

	Four months ended		Year ended		Year ended
	February 28, 2011		October 31, 2010		October 31, 2009
Beginning shares		6,591,387		6,591,387		6,591,387
Shares repurchased		—		—		—
Ending shares		6,591,387		6,591,387		6,591,387

  The Trustees have approved share repurchases 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.

NOTE 11—Dividends

The Trust declared the following dividends from net investment income subsequent to February 28, 2011:

Declaration Date	Amount Per Share		Record Date		Payable Date
March 1, 2011	$	0.0475		March 15, 2011		March 31, 2011
April 1, 2011	$	0.0475		April 15, 2011		April 29, 2011

Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of

Invesco Insured Municipal Securities:

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Invesco Insured Municipal Securities (hereafter referred to as the “Trust”) at February 28, 2011, and the results of its operations, the changes in its net assets and the financial highlights for the period ended February 28, 2011 and the year ended October 31, 2010, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Trust’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at February 28, 2011 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. The statement of changes in net assets for the year ended October 31, 2009 and the financial highlights of the Trust for the periods ended October 31, 2009 and prior were audited by other independent auditors whose report dated December 24, 2009 expressed an unqualified opinion on those financial statements.

To the extent that such services were provided, the Audit Committee determined that the provision of such services is compatible with PWC maintaining independence with respect to the Registrant.

PRE-APPROVAL OF AUDIT AND NON-AUDIT SERVICES
POLICIES AND PROCEDURES
As adopted by the Audit Committees of
the Invesco Funds (the “Funds”)
Last Amended May 4, 2010

Statement of Principles

Under the Sarbanes-Oxley Act of 2002 and rules adopted by the Securities and Exchange Commission (“SEC”) (“Rules”), the Audit Committees of the Funds’ (the “Audit Committees”) Board of Trustees (the “Board”) are responsible for the appointment, compensation and oversight of the work of independent accountants (an “Auditor”). As part of this responsibility and to assure that the Auditor’s independence is not impaired, the Audit Committees pre-approve the audit and non-audit services provided to the Funds by each Auditor, as well as all non-audit services provided by the Auditor to the Funds’ investment adviser and to affiliates of the adviser that provide ongoing services to the Funds (“Service Affiliates”) if the services directly impact the Funds’ operations or financial reporting. The SEC Rules also specify the types of services that an Auditor may not provide to its audit client. The following policies and procedures comply with the requirements for pre-approval and provide a mechanism by which management of the Funds may request and secure pre-approval of audit and non-audit services in an orderly manner with minimal disruption to normal business operations.

Proposed services either may be pre-approved without consideration of specific case-by-case services by the Audit Committees (“general pre-approval”) or require the specific pre-approval of the Audit Committees (“specific pre-approval”). As set forth in these policies and procedures, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committees. Additionally, any fees exceeding 110% of estimated pre-approved fee levels provided at the time the service was pre-approved will also require specific approval by the Audit Committees before payment is made. The Audit Committees will also consider the impact of additional fees on the Auditor’s independence when determining whether to approve any additional fees for previously pre-approved services.

The Audit Committees will annually review and generally pre-approve the services that may be provided by each Auditor without obtaining specific pre-approval from the Audit Committee generally on an annual basis. The term of any general pre-approval runs from the date of such pre-approval through September 30^th of the following year, unless the Audit Committees consider a different period and state otherwise. The Audit Committees will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations.

The purpose of these policies and procedures is to set forth the guidelines to assist the Audit Committees in fulfilling their responsibilities.

Delegation

The Audit Committees may from time to time delegate pre-approval authority to one or more of its members who are Independent Trustees. All decisions to pre-approve a service by a delegated member shall be reported to the Audit Committees at the next quarterly meeting.

Audit Services

The annual audit services engagement terms will be subject to specific pre-approval of the Audit Committees. Audit services include the annual financial statement audit and other procedures such as tax provision work that is required to be performed by the independent auditor to be able to form an opinion on the Funds’ financial statements. The Audit Committees will obtain, review and consider sufficient information concerning the proposed Auditor to make a reasonable evaluation of the Auditor’s qualifications and independence.

In addition to the annual Audit services engagement, the Audit Committees may grant either general or specific pre-approval of other audit services, which are those services that only the independent auditor reasonably can provide. Other Audit services may include services such as issuing consents for the inclusion of audited financial statements with SEC registration statements, periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings.

Non-Audit Services

The Audit Committees may provide either general or specific pre-approval of any non-audit services to the Funds and its Service Affiliates if the Audit Committees believe that the provision of the service will not impair the independence of the Auditor, is consistent with the SEC’s Rules on auditor independence, and otherwise conforms to the Audit Committees’ general principles and policies as set forth herein.

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 or that are traditionally performed by the independent auditor. 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; and agreed-upon procedures related to mergers, compliance with ratings agency requirements and interfund lending activities.

Tax Services

“Tax services” include, but are not limited to, the review and signing of the Funds’ federal tax returns, the review of required distributions by the Funds and consultations regarding tax matters such as the tax treatment of new investments or the impact of new regulations. The Audit Committees will scrutinize carefully the retention of the Auditor in connection with a transaction initially recommended by the Auditor, the major business purpose of which may be tax avoidance or the tax treatment of which may not be supported in the Internal Revenue Code and related regulations. The Audit Committees will consult with the Funds’ Treasurer (or his or her designee) and may consult with outside counsel or advisors as necessary to ensure the consistency of Tax services rendered by the Auditor with the foregoing policy.

No Auditor shall represent any Fund or any Service Affiliate before a tax court, district court or federal court of claims.

Under rules adopted by the Public Company Accounting Oversight Board and approved by the SEC, in connection with seeking Audit Committees’ pre-approval of permissible Tax services, the Auditor shall:

1. Describe in writing to the Audit Committees, which writing may be in the form of the proposed engagement letter:

a.	The scope of the service, the fee structure for the engagement, and any side letter or amendment to the engagement letter, or any other agreement between the Auditor and the Fund, relating to the service; and
b.	Any compensation arrangement or other agreement, such as a referral agreement, a referral fee or fee-sharing arrangement, between the Auditor and any person (other than the Fund) with respect to the promoting, marketing, or recommending of a transaction covered by the service;

2. Discuss with the Audit Committees the potential effects of the services on the independence of the Auditor; and

3. Document the substance of its discussion with the Audit Committees.

All Other Auditor Services

The Audit Committees may pre-approve non-audit services classified as “All other services” that are not categorically prohibited by the SEC, as listed in Exhibit 1 to this policy.

Pre-Approval Fee Levels or Established Amounts

Pre-approval of estimated fees or established amounts for services to be provided by the Auditor under general or specific pre-approval policies will be set periodically by the Audit Committees. Any proposed fees exceeding 110% of the maximum estimated pre-approved fees or established amounts for pre-approved audit and non-audit services will be reported to the Audit Committees at the quarterly Audit Committees meeting and will require specific approval by the Audit Committees before payment is made. The Audit Committees will always factor

in the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services and in determining whether to approve any additional fees exceeding 110% of the maximum pre-approved fees or established amounts for previously pre-approved services.

Procedures

Generally on an annual basis, Invesco Advisers, Inc. (“Invesco”) will submit to the Audit Committees for general pre-approval, a list of non-audit services that the Funds or Service Affiliates of the Funds may request from the Auditor. The list will describe the non-audit services in reasonable detail and will include an estimated range of fees and such other information as the Audit Committee may request.

Each request for services to be provided by the Auditor under the general pre-approval of the Audit Committees will be submitted to the Funds’ Treasurer (or his or her designee) and must include a detailed description of the services to be rendered. The Treasurer or his or her designee will ensure that such services are included within the list of services that have received the general pre-approval of the Audit Committees. The Audit Committees will be informed at the next quarterly scheduled Audit Committees meeting of any such services for which the Auditor rendered an invoice and whether such services and fees had been pre-approved and if so, by what means.

Each request to provide services that require specific approval by the Audit Committees shall be submitted to the Audit Committees jointly by the Fund’s Treasurer or his or her designee and the Auditor, and must include a joint statement that, in their view, such request is consistent with the policies and procedures and the SEC Rules.

Each request to provide tax services under either the general or specific pre-approval of the Audit Committees will describe in writing: (i) the scope of the service, the fee structure for the engagement, and any side letter or amendment to the engagement letter, or any other agreement between the Auditor and the audit client, relating to the service; and (ii) any compensation arrangement or other agreement between the Auditor and any person (other than the audit client) with respect to the promoting, marketing, or recommending of a transaction covered by the service. The Auditor will discuss with the Audit Committees the potential effects of the services on the Auditor’s independence and will document the substance of the discussion.

Non-audit services pursuant to the de minimis exception provided by the SEC Rules will be promptly brought to the attention of the Audit Committees for approval, including documentation that each of the conditions for this exception, as set forth in the SEC Rules, has been satisfied.

On at least an annual basis, the Auditor will prepare a summary of all the services provided to any entity in the investment company complex as defined in section 2-01(f)(14) of Regulation S-X in sufficient detail as to the nature of the engagement and the fees associated with those services.

The Audit Committees have designated the Funds’ Treasurer to monitor the performance of all services provided by the Auditor and to ensure such services are in compliance with these policies and procedures. The Funds’ Treasurer will report to the Audit Committees on a periodic basis as to the results of such monitoring. Both the Funds’ Treasurer and management of Invesco will immediately report to the chairman of the Audit Committees any breach of these policies and procedures that comes to the attention of the Funds’ Treasurer or senior management of Invesco.

The following policies and procedures apply to all institutional accounts, clients and funds managed by Invesco Advisers, Inc. (“Invesco”). These policies and procedures do not apply to any of the retail funds managed by Invesco. See Section I.2 for the proxy policies and procedures applicable to Invesco’s retail funds.

A. POLICY STATEMENT

Invesco has responsibility for making investment decisions that are in the best interests of its clients. As part of the investment management services it provides to clients, Invesco may be authorized by clients to vote proxies appurtenant to the shares for which the clients are beneficial owners.

Invesco believes that it has a duty to manage clients’ assets in the best economic interests of its clients and that the ability to vote proxies is a client asset.

Invesco reserves the right to amend its proxy policies and procedures from time to time without prior notice to its clients.

Voting of Proxies

Invesco will vote client proxies relating to equity securities in accordance with the procedures set forth below unless a non-ERISA client retains in writing the right to vote, the named fiduciary (e.g., the plan sponsor) of an ERISA client retains in writing the right to direct the plan trustee or a third party to vote proxies, or Invesco determines that any benefit the client might gain from voting a proxy

January 2010 I.1 — 1

would be outweighed by the costs associated therewith. In addition, due to the distinct nature of proxy voting for interests in fixed income assets and stable value wrap agreements, the proxies for such fixed income assets and stable value wrap agreements will be voted in accordance with the procedures set forth in the “Proxy Voting for Fixed Income Assets and Stable Value Wrap Agreements” section below.

Best Economic Interests of Clients

In voting proxies, Invesco will take into consideration those factors that may affect the value of the security and will vote proxies in a manner in which, in its opinion, is in the best economic interests of clients. Invesco endeavors to resolve any conflicts of interest exclusively in the best economic interests of clients.

B. OPERATING PROCEDURES AND RESPONSIBLE PARTIES

RiskMetrics’ Services

Invesco has contracted with RiskMetrics Group (“RiskMetrics,” formerly known as ISS), an independent third party service provider, to vote Invesco’s clients’ proxies according to RiskMetrics’ proxy voting recommendations determined by RiskMetrics pursuant to its then-current US Proxy Voting Guidelines, a summary of which can be found at http://www.riskmetrics.com and which are deemed to be incorporated herein. In addition, RiskMetrics will provide proxy analyses, vote recommendations, vote execution and record-keeping services for clients for which Invesco has proxy voting responsibility. On an annual basis, the Proxy Committee will review information obtained from RiskMetrics to ascertain whether RiskMetrics (i) has the capacity and competency to adequately analyze proxy issues, and (ii) can make such recommendations in an impartial manner and in the best economic interests of Invesco’s clients. This may include a review of RiskMetrics’ Policies, Procedures and Practices Regarding Potential Conflicts of Interest and obtaining information about the work RiskMetrics does for corporate issuers and the payments RiskMetrics receives from such issuers.

Custodians forward to RiskMetrics proxy materials for clients who rely on Invesco to vote proxies. RiskMetrics is responsible for exercising the voting rights in accordance with the RiskMetrics proxy voting guidelines. If Invesco receives proxy materials in connection with a client’s account where the client has, in writing, communicated to Invesco that the client, plan fiduciary or other third party has reserved the right to vote proxies, Invesco will forward to the party appointed by client any proxy materials it receives with respect to the account. In order to avoid voting proxies in circumstances where Invesco, or any of its affiliates have or may have any conflict of interest, real or perceived, Invesco has engaged RiskMetrics to provide the proxy analyses, vote recommendations and voting of proxies.

In the event that (i) RiskMetrics recuses itself on a proxy voting matter and makes no recommendation or (ii) Invesco decides to override the RiskMetrics vote recommendation, the Proxy Committee will review the issue and direct RiskMetrics how to vote the proxies as described below.

January 2010 I.1 — 2

Proxy Voting for Fixed Income Assets and Stable Value Wrap Agreements

Some of Invesco’s fixed income clients hold interests in preferred stock of companies and some of Invesco’s stable value clients are parties to wrap agreements. From time to time, companies that have issued preferred stock or that are parties to wrap agreements request that Invesco’s clients vote proxies on particular matters. RiskMetrics does not currently provide proxy analysis or vote recommendations with respect to such proxy votes. Therefore, when a particular matter arises in this category, the investment team responsible for the particular mandate will review the matter and make a recommendation to the Proxy Manager as to how to vote the associated proxy. The Proxy Manager will complete the proxy ballots and send the ballots to the persons or entities identified in the ballots.

Proxy Committee

The Proxy Committee shall have seven (7) members, which shall include representatives from portfolio management, operations, and legal/compliance or other functional departments as deemed appropriate and who are knowledgeable regarding the proxy process. A majority of the members of the Proxy Committee shall constitute a quorum and the Proxy Committee shall act by a majority vote of those members in attendance at a meeting called for the purpose of determining how to vote a particular proxy. The Proxy Committee shall keep minutes of its meetings that shall be kept with the proxy voting records of Invesco. The Proxy Committee will appoint a Proxy Manager to manage the proxy voting process, which includes the voting of proxies and the maintenance of appropriate records.

The Proxy Manager shall call for a meeting of the Proxy Committee (1) when override submissions are made; and (2) in instances when RiskMetrics has recused itself or has not provided a vote recommendation with respect to an equity security. At such meeting, the Proxy Committee shall determine how proxies are to be voted in accordance with the factors set forth in the section entitled “Best Economic Interests of Clients,” above.

The Proxy Committee also is responsible for monitoring adherence to these procedures and engaging in the annual review described in the section entitled “RiskMetrics’ Services,” above.

Recusal by RiskMetrics or Failure of RiskMetrics to Make a Recommendation

When RiskMetrics does not make a recommendation on a proxy voting issue or recuses itself due to a conflict of interest, the Proxy Committee will review the issue and determine whether Invesco has a material conflict of interest as determined pursuant to the policies and procedures outlined in the “Conflicts of Interest” section below. If Invesco determines it does not have a material conflict of interest, Invesco will direct RiskMetrics how to vote the proxies. If Invesco determines it does have a material conflict of interest, the Proxy Committee will follow the policies and procedures set forth in such section.

January 2010 I.1 — 3

Override of RiskMetrics’ Recommendation

There may be occasions where Invesco investment personnel, senior officers or a member of the Proxy Committee seek to override a RiskMetrics recommendation if they believe that a RiskMetrics recommendation is not in accordance with the best economic interests of clients. In the event that an individual listed above in this section disagrees with a RiskMetrics recommendation on a particular voting issue, the individual shall document in writing the reasons that he/she believes that the RiskMetrics recommendation is not in accordance with clients’ best economic interests and submit such written documentation to the Proxy Manager for consideration by the Proxy Committee along with the certification attached as Appendix A hereto. Upon review of the documentation and consultation with the individual and others as the Proxy Committee deems appropriate, the Proxy Committee may make a determination to override the RiskMetrics voting recommendation if the Committee determines that it is in the best economic interests of clients and the Committee has addressed any conflict of interest.

Proxy Committee Meetings

When a Proxy Committee Meeting is called, whether because of a RiskMetrics recusal or request for override of a RiskMetrics recommendation, the Proxy Committee shall request from the Chief Compliance Officer as to whether any Invesco person has reported a conflict of interest.

The Proxy Committee shall review the report from the Chief Compliance Officer to determine whether a real or perceived conflict of interest exists, and the minutes of the Proxy Committee shall:

(1)	describe any real or perceived conflict of interest,
(2)	determine whether such real or perceived conflict of interest is material,
(3)	discuss any procedure used to address such conflict of interest,
(4)	report any contacts from outside parties (other than routine communications from proxy solicitors), and
(5)	include confirmation that the recommendation as to how the proxies are to be voted is in the best economic interests of clients and was made without regard to any conflict of interest.

Based on the above review and determinations, the Proxy Committee will direct RiskMetrics how to vote the proxies as provided herein.

Certain Proxy Votes May Not Be Cast

In some cases, Invesco may determine that it is not in the best economic interests of clients to vote proxies. For example, proxy voting in certain countries outside

January 2010 I.1 — 4

the United States requires share blocking. Shareholders who wish to vote their proxies must deposit their shares 7 to 21 days before the date of the meeting with a designated depositary. During the blocked period, shares to be voted at the meeting cannot be sold until the meeting has taken place and the shares have been returned to the Custodian/Sub-Custodian bank. In addition, voting certain international securities may involve unusual costs to clients, some of which may be related to requirements of having a representative in person attend the proxy meeting. In other cases, it may not be possible to vote certain proxies despite good faith efforts to do so, for instance when inadequate notice of the matter is provided. In the instance of loan securities, voting of proxies typically requires termination of the loan, so it is not usually in the best economic interests of clients to vote proxies on loaned securities. Invesco typically will not, but reserves the right to, vote where share blocking restrictions, unusual costs or other barriers to efficient voting apply. Invesco will not vote if it determines that the cost of voting exceeds the expected benefit to the client. The Proxy Manager shall record the reason for any proxy not being voted, which record shall be kept with the proxy voting records of Invesco.

CONFLICTS OF INTEREST

Procedures to Address Conflicts of Interest and Improper Influence

In order to avoid voting proxies in circumstances where Invesco or any of its affiliates have or may have any conflict of interest, real or perceived, Invesco has contracted with RiskMetrics to provide proxy analyses, vote recommendations and voting of proxies. Unless noted otherwise by RiskMetrics, each vote recommendation provided by RiskMetrics to Invesco shall include a representation from RiskMetrics that RiskMetrics has no conflict of interest with respect to the vote. In instances where RiskMetrics has recused itself or makes no recommendation on a particular matter, or if an override submission is requested, the Proxy Committee shall determine how to vote the proxy and instruct the Proxy Manager accordingly, in which case the conflict of interest provisions discussed below shall apply.

In effecting the policy of voting proxies in the best economic interests of clients, there may be occasions where the voting of such proxies may present a real or perceived conflict of interest between Invesco, as the investment manager, and Invesco’s clients. For each director, officer and employee of Invesco (“Invesco person”), the interests of Invesco’s clients must come first, ahead of the interest of Invesco and any Invesco person, including Invesco’s affiliates. Accordingly, no Invesco person may put “personal benefit,” whether tangible or intangible, before the interests of clients of Invesco or otherwise take advantage of the relationship with Invesco’s clients. “Personal benefit” includes any intended benefit for oneself or any other individual, company, group or organization of any kind whatsoever, except a benefit for a client of Invesco, as appropriate. It is imperative that each Invesco person avoid any situation that might compromise, or call into question, the exercise of fully independent judgment that is in the interests of Invesco’s clients.

January 2010 I.1 — 5

Occasions may arise where a person or organization involved in the proxy voting process may have a conflict of interest. A conflict of interest may exist if Invesco has a business relationship with (or is actively soliciting business from) either the company soliciting the proxy or a third party that has a material interest in the outcome of a proxy vote or that is actively lobbying for a particular outcome of a proxy vote. Additional examples of situations where a conflict may exist include:

• Business Relationships — where Invesco manages money for a company or an employee group, manages pension assets or is actively soliciting any such business, or leases office space from a company;

• Personal Relationships — where an Invesco person has a personal relationship with other proponents of proxy proposals, participants in proxy contests, corporate directors, or candidates for directorships; and

• Familial Relationships — where an Invesco person has a known familial relationship relating to a company (e.g. a spouse or other relative who serves as a director of a public company or is employed by the company).

In the event that the Proxy Committee determines that Invesco (or an affiliate) has a material conflict of interest, the Proxy Committee will not take into consideration the relationship giving rise to the conflict of interest and shall, in its sole discretion, either (a) decide to vote the proxies pursuant to RiskMetrics’ general proxy voting guidelines, (b) engage an independent third party to provide a vote recommendation, or (c) contact Invesco’s client(s) for direction as to how to vote the proxies.

In the event an Invesco person has a conflict of interest and has knowledge of such conflict of interest, it is the responsibility of such Invesco person to disclose the conflict to the Chief Compliance Officer. When a Proxy Committee meeting is called, the Chief Compliance Officer will report to the Proxy Committee all real or potential conflicts of interest for the Proxy Committee to review and determine whether such conflict is material. If the Proxy Committee determines that such conflict is material and involves a person involved in the proxy voting process, the Proxy Committee may require such person to recuse himself or herself from participating in the discussions regarding the proxy vote item and from casting a vote regarding how Invesco should vote such proxy. An Invesco person will not be considered to have a material conflict of interest if the Invesco person did not know of the conflict of interest and did not attempt to influence the outcome of a proxy vote.

In order to ensure compliance with these procedures, the Proxy Manager and each member of the Proxy Committee shall certify annually as to their compliance with this policy. In addition, any Invesco person who submits a RiskMetrics override recommendation to the Proxy Committee shall certify as to their compliance with this policy concurrently with the submission of their override recommendation. A form of such certification is attached as Appendix A.

January 2010 I.1 — 6

In addition, members of the Proxy Committee must notify Invesco’s Chief Compliance Officer, with impunity and without fear of retribution or retaliation, of any direct, indirect or perceived improper influence exerted by any Invesco person or by an affiliated company’s representatives with regard to how Invesco should vote proxies. The Chief Compliance Officer will investigate the allegations and will report his or her findings to the Invesco Risk Management Committee. In the event that it is determined that improper influence was exerted, the Risk Management Committee will determine the appropriate action to take, which actions may include, but are not limited to, (1) notifying the affiliated company’s Chief Executive Officer, its Management Committee or Board of Directors, (2) taking remedial action, if necessary, to correct the result of any improper influence where clients have been harmed, or (3) notifying the appropriate regulatory agencies of the improper influence and cooperating fully with these regulatory agencies as required. In all cases, the Proxy Committee shall not take into consideration the improper influence in determining how to vote proxies and will vote proxies solely in the best economic interests of clients.

C. RECORDKEEPING

Records are maintained in accordance with Invesco’s Recordkeeping Policy.

Proxy Voting Records

The proxy voting statements and records will be maintained by the Proxy Manager on-site (or accessible via an electronic storage site of RiskMetrics) for the first two (2) years. Copies of the proxy voting statements and records will be maintained for an additional five (5) years by Invesco (or will be accessible via an electronic storage site of RiskMetrics). Clients may obtain information about how Invesco voted proxies on their behalf by contacting their client services representative. Alternatively, clients may make a written request for proxy voting information to: Proxy Manager, 1555 Peachtree Street, N.E., Atlanta, Georgia 30309.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

The following individuals are jointly and primarily responsible for the day-to-day management of the Trust:

• Thomas Byron, Portfolio Manager, who has been responsible for the Trust since 2009 and has been associated with Invesco and/or its affiliates since 2010. From 1981 to 2010, Mr. Byron was associated with Morgan Stanley Investment Advisors Inc. in an investment management capacity.

• Robert Stryker, Portfolio Manager, who has been responsible for the Trust since 2009 and has been associated with Invesco and/or its affiliates since 2010. From 1994 to 2010, Mr. Stryker was associated with Morgan Stanley Investment Advisors Inc. in an investment management capacity.

• Robert Wimmel, Portfolio Manager, who has been responsible for the Trust since 2009 and has been associated with Invesco and/or its affiliates since 2010. From 1996 to 2010, Mr. Wimmel was associated with Morgan Stanley Investment Advisors Inc. in an investment management capacity.

Portfolio Manager Fund Holdings and Information on Other Managed Accounts

Invesco’s portfolio managers develop investment models which are used in connection with the management of certain Invesco Funds as well as other mutual funds for which Invesco or an affiliate acts as sub-adviser, other pooled investment vehicles that are not registered mutual funds, and other accounts managed for organizations and individuals. The following chart reflects the portfolio managers’ investments in the Funds that they manage. The chart also reflects information regarding accounts other than the Funds for which each portfolio manager has day-to-day management responsibilities. Accounts are grouped into three categories: (i) other registered investment companies, (ii) other pooled investment vehicles and (iii) other accounts. To the extent that any of these accounts pay advisory fees that are based on account performance (performance-based fees), information on those accounts is specifically broken out. In addition, any assets denominated in foreign currencies have been converted into U.S. Dollars using the exchange rates as of the applicable date.

The following information is as of February 28, 2011:

Potential Conflicts of Interest

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one Fund or other account. More specifically, portfolio managers who

¹ This column reflects investments in a Fund’s shares owned directly by a portfolio manager or beneficially owned by a portfolio manager (as determined in accordance with Rule 16a-1(a) (2) under the Securities Exchange Act of 1934, as amended). A portfolio manager is presumed to be a beneficial owner of securities that are held by his or her immediate family members sharing the same household.

manage multiple Funds and/or other accounts may be presented with one or more of the following potential conflicts:

Ø	The management of multiple Funds and/or other accounts may result in a portfolio manager devoting unequal time and attention to the management of each Fund and/or other account. The Adviser and each Sub-Adviser seek to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most other accounts managed by a portfolio manager are managed using the same investment models that are used in connection with the management of the Funds.
Ø	If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one Fund or other account, a Fund may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible Funds and other accounts. To deal with these situations, the Adviser, each Sub-Adviser and the Funds have adopted procedures for allocating portfolio transactions across multiple accounts.
Ø	The Adviser and each Sub-Adviser determine which broker to use to execute each order for securities transactions for the Funds, consistent with its duty to seek best execution of the transaction. However, for certain other accounts (such as mutual funds for which Invesco or an affiliate acts as sub-adviser, other pooled investment vehicles that are not registered mutual funds, and other accounts managed for organizations and individuals), the Adviser and each Sub-Adviser may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, trades for a Fund in a particular security may be placed separately from, rather than aggregated with, such other accounts. Having separate transactions with respect to a security may temporarily affect the market price of the security or the execution of the transaction, or both, to the possible detriment of the Fund or other account(s) involved.
Ø	Finally, the appearance of a conflict of interest may arise where the Adviser or Sub-Adviser has an incentive, such as a performance-based management fee, which relates to the management of one Fund or account but not all Funds and accounts for which a portfolio manager has day-to-day management responsibilities.

     The Adviser, each Sub-Adviser, and the Funds have adopted certain compliance procedures which are designed to address these types of conflicts. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

Description of Compensation Structure

For the Adviser and each affiliated Sub-Adviser

     The Adviser and each Sub-Adviser seek to maintain a compensation program that is competitively positioned to attract and retain high-caliber investment professionals. Portfolio managers receive a base salary, an incentive bonus opportunity and an equity compensation opportunity. Portfolio manager compensation is reviewed and may be modified each year as appropriate to reflect changes in the market, as well as to adjust the factors used to determine bonuses to promote competitive Fund performance. The Adviser and each Sub-Adviser evaluate competitive market compensation by reviewing compensation survey results conducted by an independent third party of investment industry compensation. Each portfolio manager’s compensation consists of the following three elements:

     Base Salary. Each portfolio manager is paid a base salary. In setting the base salary, the Adviser and each Sub-Adviser’s intention is to be competitive in light of the particular portfolio manager’s experience and responsibilities.

     Annual Bonus. The portfolio managers are eligible, along with other employees of the Adviser and each Sub-Adviser, to participate in a discretionary year-end bonus pool. The Compensation Committee of Invesco Ltd. reviews and approves the amount of the bonus pool available for the Adviser and each of the Sub-Adviser’s investment centers. The Compensation Committee considers investment performance and financial results in its review. In addition, while having no direct impact on individual bonuses, assets under management are considered when determining the starting bonus funding levels. Each portfolio manager is eligible to receive an annual cash bonus which is based on quantitative (i.e. investment performance) and non-quantitative factors (which may include, but are not limited to, individual performance, risk management and teamwork).

     Each portfolio manager’s compensation is linked to the pre-tax investment performance of the Funds/accounts managed by the portfolio manager as described in Table 1 below.

Table 1

Sub-Adviser	Performance time period2
Invesco 3,4,5 Invesco Australia	One-, Three- and Five-year performance against Fund peer group.
Invesco Deutschland
Invesco Senior Secured	N/A
Invesco Trimark3	One-year performance against Fund peer group. Three- and Five-year performance against entire universe of Canadian funds.
Invesco Hong Kong3 Invesco Asset Management	One-, Three- and Five-year performance against Fund peer group.
Invesco Japan6	One-, Three- and Five-year performance against the appropriate Micropol benchmark.

     Invesco Senior Secured’s bonus is based on annual measures of equity return and standard tests of collateralization performance.

     High investment performance (against applicable peer group and/or benchmarks) would deliver compensation generally associated with top pay in the industry (determined by reference to the third-party provided compensation survey information) and poor investment performance (versus applicable peer group) would result in low bonus compared to the applicable peer group or no bonus at all. These decisions are reviewed and approved collectively by senior leadership which has responsibility for executing the compensation approach across the organization.

     Equity-Based Compensation. Portfolio managers may be granted an award that allows them to select receipt of shares of certain Invesco Funds with a vesting period as well as common shares and/or restricted shares of Invesco Ltd. stock from pools determined from time to time by the Compensation Committee of Invesco Ltd.’s Board of Directors. Awards of equity-based compensation typically vest over time, so as to create incentives to retain key talent.

     Portfolio managers also participate in benefit plans and programs available generally to all employees.

2	Rolling time periods based on calendar year-end.
3	Portfolio Managers may be granted a short-term award that vests on a pro-rata basis over a four year period and final payments are based on the performance of eligible Funds selected by the portfolio manager at the time the award is granted.
4	Portfolio Managers for Invesco Global Real Estate Fund, Invesco Real Estate Fund, Invesco Select Real Estate Income Fund and Invesco V.I. Global Real Estate Fund base their bonus on new operating profits of the U.S. Real Estate Division of Invesco.

EXHIBIT — CODE OF ETHICS

DISCLOSURE CONTROLS PROCEDURE

THE AIM FAMILY OF FUNDS CODE OF ETHICS FOR SENIOR OFFICERS

I. INTRODUCTION

The Boards of Directors/Trustees (“Board”) of the Invesco Funds (the “Companies”) have adopted this code of ethics (this “Code”) applicable to their Principal Executive Officer and Principal Financial and Accounting Officer (the “Covered Officers”) to promote:

• honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

• full, fair, accurate, timely and understandable disclosure in documents filed with the Securities and Exchange Commission (“SEC”) and in other public communications;

• compliance with applicable governmental laws, rules and regulations;

• the prompt internal reporting to an appropriate person or persons identified in the Code of violations of the Code; and

• accountability for adherence to the Code.

II. COVERED OFFICERS SHOULD ACT HONESTLY AND CANDIDLY

Each Covered Officer named in Exhibit A to this Code owes a duty to the Companies to act with integrity. Integrity requires, among other things, being honest and candid. Deceit and subordination of principle are inconsistent with integrity.

Each Covered Officer must:

• act with integrity, including being honest and candid while still maintaining the confidentiality of information where required by law or the Companies’ policies;

• observe both the form and spirit of laws and governmental rules and regulations, accounting standards and policies of the Companies;

• adhere to a high standard of business ethics; and

• place the interests of the Companies before the Covered Officer’s own personal interests.

Business practices Covered Officers should be guided by and adhere to these fiduciary standards.

III. COVERED OFFICERS SHOULD HANDLE ETHICALLY ACTUAL AND APPARENT CONFLICTS OF INTEREST

     GUIDING PRINCIPLES. A “conflict of interest” occurs when an individual’s private interest interferes with the interests of the Companies. A conflict of interest can arise when a Covered Officer takes actions or has interests that may make it difficult to perform his or her work for the Companies objectively and effectively. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his or her position in any of the Companies. In addition, investment companies should be sensitive to situations that create apparent, but not actual, conflicts of interest. Service to the Companies should never be subordinated to personal gain and advantage.

     Certain conflicts of interest covered by this Code arise out of the relationships between Covered Officers and the Companies that already are subject to conflict of interest provisions in the Investment

Company Act of 1940, as amended and the Investment Advisers Act of 1940, as amended. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Companies because of their status as “affiliated persons” of the Companies. Therefore, as to the existing statutory and regulatory prohibitions on individual behavior, they will be deemed to be incorporated in this Code and therefore any material violation will also be deemed a violation of this Code. Covered Officers must in all cases comply with applicable statutes and regulations.

     As to conflicts arising from, or as a result of the contractual relationship between, the Companies and the investment adviser of which the Covered Officers are also officers or employees, it is recognized by the Board that, subject to the adviser’s fiduciary duties to the Companies, the Covered Officers will in the normal course of their duties (whether formally for the Companies or for the adviser, or for both) be involved in establishing policies and implementing decisions which will have different effects on the adviser and the Companies. The Board recognizes that the participation of the Covered Officers in such activities is inherent in the contractual relationship between the Companies and the adviser and is consistent with the expectation of the Board of the performance by the Covered Officers of their duties as officers of the Companies. In addition, it is recognized by the Board that the Covered Officers may also be officers or employees of other investment companies advised by the same adviser and the codes which apply to senior officers of those investment companies will apply to the Covered Officers acting in those distinct capacities.

     Each Covered Officer must:

• avoid conflicts of interest wherever possible;

• handle any actual or apparent conflict of interest ethically;

• not use his or her personal influence or personal relationships to influence investment decisions or financial reporting by an investment company whereby the Covered Officer would benefit personally to the detriment of any of the Companies;

• not cause an investment company to take action, or fail to take action, for the personal benefit of the Covered Officer rather than the benefit of such company;

• not use knowledge of portfolio transactions made or contemplated for an investment company to profit or cause others to profit, by the market effect of such transactions; and

• as described in more detail below, discuss any material transaction or relationship that could reasonably be expected to give rise to a conflict of interest with the Chief Legal Officer of the Invesco Funds (the “Chief Legal Officer”).

Some conflict of interest situations that should always be discussed with the Chief Legal Officer, if material, include the following:

• any outside business activity that detracts from an individual’s ability to devote appropriate time and attention to his or her responsibilities with the Companies;

• being in the position of supervising, reviewing or having any influence on the job evaluation, pay or benefit of any immediate family member;

• any direct ownership interest in, or any consulting or employment relationship with, any of the Companies’ service providers, other than its investment adviser, distributor or other Invesco Ltd. affiliated entities and other than a de minimis ownership interest (for purposes of this section of the Code an ownership interest of 1% or less shall constitute a de minimis ownership interest, and an ownership interest of more than 1% creates a rebuttable presumption that there may be a material conflict of interest); and

• a direct or indirect financial interest in commissions, transaction charges or spreads paid by the Companies for effecting portfolio transactions or for selling or redeeming shares, other than an

interest arising from the Covered Officer’s employment with Invesco, its subsidiaries, its parent organizations and any affiliates or subsidiaries thereof, such as compensation or equity ownership, and other than an interest arising from a de minimis ownership interest in a company with which the Companies execute portfolios transactions or a company that receives commissions or other fees related to its sales and redemptions of shares of the Companies (for purposes of this section of the Code an ownership interest of 1% or less shall constitute a de minimis ownership interest, and an ownership interest of more than 1% creates a rebuttable presumption that there may be a material conflict of interest).

IV. DISCLOSURE

Each Covered Officer is required to be familiar, and comply, with the Companies’ disclosure controls and procedures so that the Companies’ subject reports and documents filed with the SEC comply in all material respects with the applicable federal securities laws and SEC rules. In addition, each Covered Officer having direct or supervisory authority regarding these SEC filings or the Companies’ other public communications should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Companies and take other appropriate steps regarding these disclosures with the goal of making full, fair, accurate, timely and understandable disclosure.

     Each Covered Officer must:

• familiarize himself/herself with the disclosure requirements applicable to the Companies as well as the business and financial operations of the Companies; and

• not knowingly misrepresent, or cause others to misrepresent, facts about the Companies to others, whether within or outside the Companies, including representations to the Companies’ internal auditors, independent Directors/Trustees, independent auditors, and to governmental regulators and self-regulatory organizations.

V. COMPLIANCE

It is the Companies’ policy to comply in all material respects with all applicable governmental laws, rules and regulations. It is the personal responsibility of each Covered Officer to adhere to the standards and restrictions imposed by those laws, rules and regulations, including those relating to affiliated transactions, accounting and auditing matters.

VI. REPORTING AND ACCOUNTABILITY

     Each Covered Officer must:

• upon receipt of the Code, sign and submit to the Chief Compliance Officer of the Companies an acknowledgement stating that he or she has received, read, and understands the Code.

• annually thereafter submit a form to the Chief Compliance Officer of the Companies confirming that he or she has received, read and understands the Code and has complied with the requirements of the Code.

• not retaliate against any employee or other Covered Officer for reports of potential violations that are made in good faith.

• notify the Chief Legal Officer promptly if he becomes aware of any existing or potential violation of this Code. Failure to do so is itself a violation of this Code.

Except as described otherwise below, the Chief Legal Officer is responsible for applying this Code to specific situations in which questions are presented to him or her and has the authority to interpret this Code in any particular situation. The Chief Legal Officer shall take all action he or she considers appropriate to investigate any actual or potential violations reported to him or her.

The Chief Legal Officer is authorized to consult, as appropriate, with the Chairman of the Audit Committees of the Board, counsel to the Companies and counsel to the independent Directors/Trustees, and is encouraged to do so.

The Chief Legal Officer is responsible for granting waivers and determining sanctions, as appropriate. In addition, approvals, interpretations, or waivers sought by the Covered Officers may also be considered by the Chairman of the Invesco Funds Audit Committees.

The Companies will follow these procedures in investigating and enforcing this Code, and in reporting on the Code:

• the Chief Legal Officer will take all appropriate action to investigate any violations reported to him or her;

• violations and potential violations will be reported to the Chairman of the Audit Committees of the Board after such investigation;

• if the Chairman of the Audit Committees determines that a violation has occurred, he or she will inform the Board, which will take all appropriate disciplinary or preventive action;

• appropriate disciplinary or preventive action may include a letter of censure, suspension, dismissal or, in the event of criminal or other serious violations of law, notification to the SEC or other appropriate law enforcement authorities;

• the Chief Legal Officer will be responsible for granting waivers, as appropriate; and

• any changes to or waivers of this Code will, to the extent required, be disclosed on Form N-CSR as provided by SEC rules.

VII. OTHER POLICIES AND PROCEDURES

The Companies’ and the Advisers’ and Principal Underwriters’ codes of ethics under Rule 17j-1 under the Investment Company Act and the Advisers’ more detailed policies and procedures set forth in its Compliance and Supervisory Procedures Manual are separate requirements applying to Covered Officers and others, and are not part of this Code.

VIII. AMENDMENTS

This Code may not be amended except in written form, which is specifically approved by a majority vote of the Companies’ Board, including a majority of independent Directors/Trustees.

IX. CONFIDENTIALITY

All reports and records prepared or maintained pursuant to this Code shall be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the members of the Companies’ Board, counsel to the Companies, and counsel to the independent Directors/Trustees.
