Letters to Shareholders

Bruce Crockett

Dear Fellow Shareholders:

One of our most important responsibilities as independent Trustees of the Invesco Funds is our annual review of the funds’ advisory and sub-advisory contracts with Invesco. This annual review is required by the Investment Company Act of 1940 and focuses on the nature and quality of the services Invesco has provided as adviser to the Invesco Funds and the reasonableness of the fees that it charges for those services.

In our roles as Trustees, we spend months reviewing thousands of pages of detailed information that we request from Invesco in connection with our annual review. We focus on the quality and costs of the services to be provided by Invesco and its affiliates. Some of the most important things we look at are fund performance, expenses and fees.

We also use information from many independent sources during the review process, including materials provided by the independent Senior Officer of the Invesco Funds, who reports directly to the independent Trustees. We also meet in private sessions with independent legal counsel and review performance and fee data on the Invesco Funds prepared by Lipper Inc., an independent, third-party firm widely recognized as a leader in its field.

I’m pleased to report that the Invesco Funds Board determined in June that renewing the investment advisory agreement and the sub-advisory contracts with Invesco would serve the best interests of each fund and its shareholders. For more detailed information about our assessment and conclusions with respect to each of the Invesco Funds, visit invesco.com/us, click on the “About Us” section and go to “Legal Information.” Information on the recent investment advisory renewal process can be found by clicking the last item under “Corporate Governance.”

As always, please contact me at bruce@brucecrockett.com with any questions or concerns you may have. On behalf of the Board, we look forward to continuing to represent your interests and serving your needs.

Sincerely,

-s- Bruce L. Crockett

Dear Shareholders:

This report contains helpful information about your Fund, including a complete list of your Fund’s investments as of the close of the reporting period. Additional information, including timely insight and information from many of Invesco’s investment professionals, is available at our website, invesco.com/us. There, you also can access information about your Invesco account at any time.

Intentional Investing^SM is the science and art of investing with purpose, prudence and diligence – and it’s how Invesco’s investment professionals manage your money every day. This highly disciplined process begins when specialized teams of investment professionals clearly define an investment objective and then establish specific investment strategies to try to achieve that objective. While our investment teams closely monitor economic and market conditions – and issues specific to individual holdings that could affect their value – they maintain a long-term investment perspective. Intentional Investing is also embedding risk controls and processes into every aspect of our business; offering a diverse combination of investment strategies and vehicles designed to meet your needs; and communicating clearly, delivering expert insights from our portfolio managers and other investment professionals, and providing a website full of tools and articles to help you stay informed. However, neither Intentional Investing nor diversification can guarantee a profit or protect against loss.

If you have questions about your account, please contact an Invesco client services representative at 800 959 4246. If you have an Invesco-related question or comment, feel free to email me directly at phil@invesco.com. 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,

Trust Performance

Performance summary

Cumulative total returns, 2/29/12 to 8/31/12


Trust at NAV	5.27	%

Trust at Market Value	7.22

Barclays Municipal Bond Index^▼	2.94

Market Price Discount to NAV as of 8/31/12	-0.31

Source(s): ^▼Lipper Inc.

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/us 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.

The Barclays Municipal Bond Index is an unmanaged index considered representative of the tax-exempt bond market.

The Trust is not managed to track the performance of any particular index, including the index(es) defined here, and consequently, the performance of the Trust may deviate significantly from the performance of the index(es).

A direct investment cannot be made in an index. Unless otherwise indicated, index results include reinvested dividends, and they do not reflect sales charges.

Trust Updates

Preferred Shares

On May 17, 2012, the Trust successfully priced and placed a private offering of Variable Rate Muni Term Preferred Shares (“VMTP”) in the amount of $45,300,000 pursuant to an offering exempt from registration under the Securities Act of 1933. VMTP is a variable rate form of preferred stock with a mandatory redemption date. The proceeds of the VMTP were used to redeem all of the Trust’s outstanding auction rate preferred shares (“ARPS”) at their liquidation preference (sometimes referred to as “at par”), together with accrued and unpaid dividends, if any, to the redemption date. As of June 21, 2012, all of the Trust’s ARPS were redeemed in full.

Mergers and Redomestication

At a shareholder meeting held on September 25, 2012, shareholders approved the merger of each of the Trust and Invesco Quality Municipal Investment Trust (the “Target Funds”) into Invesco Quality Municipal Income Trust (the “Acquiring Fund”). Shareholders also approved the redomestication of the Trust to a Delaware statutory trust. The redomestication and mergers were completed on October 15, 2012, and common shares of the Target Funds were converted into newly issued common shares of the Acquiring Fund. VMTP shares of the Target Funds were converted into newly issued VMTP shares of the Acquiring Fund.

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 one week before such Distributions are paid. If your authorization arrives after such record date, your participation in the Plan will begin with the following Distributions.

How the Plan Works

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

Costs of the Plan

There is no direct charge to you for reinvesting Distributions because the Plan’s fees are paid by your Trust. However, you will pay your portion of any per share fees incurred when the new shares are purchased on the open market. These fees are typically less than the standard brokerage charges for individual transactions, because shares are purchased for all Participants in blocks, resulting in lower commissions for each individual Participant. Any per share or service fees are averaged into the purchase price. Per share fees include any applicable brokerage commissions the Agent is required to pay.

Tax implications

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

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

How to withdraw from the Plan

You may withdraw from the Plan at any time by calling 800 341 2929, visiting invesco.com/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:

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.

NOTE 1—Significant Accounting Policies

Invesco Quality Municipal Securities (the “Trust”), a Massachusetts business trust, is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, closed-end series management investment company.

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

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


A.		Security Valuations — Securities, including restricted securities, are valued according to the following policy.
		Securities are fair valued using an evaluated quote provided by an independent pricing service approved by the Board of Trustees. Evaluated quotes provided by the pricing service may be determined without exclusive reliance on quoted prices and may reflect appropriate factors such as institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, individual trading characteristics and other market data. 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.

16 Invesco Quality Municipal Securities


		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.
		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 to common shareholders. Distributions from net realized capital gain, if any, are generally paid annually and are distributed on a pro rata basis to common and preferred shareholders. 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 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.		Interest, Facilities and Maintenance Fees — Interest, Facilities and Maintenance Fees include interest and related borrowing costs such as commitment fees, rating and bank agent fees and other expenses associated with lines of credit, Variable Rate Muni Term Preferred Shares (“VMTP Shares”) and interest and administrative expenses related to establishing and maintaining Auction Rate Preferred Shares and floating rate note obligations, if any.
G.		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.
H.		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 the 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.
I.		Cash and Cash Equivalents — For the purposes of the Statement of Cash Flows the Trust defines Cash and Cash Equivalents as cash (including foreign currency), money market funds and other investments held in lieu of cash and excludes investments made with cash collateral received.
J.		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 interests 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

17 Invesco Quality Municipal Securities


		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 invests 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 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.
K.		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.

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 of 0.27% of the Trust’s average weekly managed assets.

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 Canada 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(s) discretionary investment management services to the Trust based on the percentage of assets allocated to such Sub-Adviser(s).

The Adviser had contractually agreed, through June 30, 2012, to waive advisory fees and/or reimburse expenses to the extent necessary to limit the Trust’s expenses (excluding certain items discussed below) to 0.66%. 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, including litigation expenses; and (5) expenses that the Trust has incurred but did not actually pay because of an expense offset arrangement. The fee waiver agreement terminated on June 30, 2012. The Adviser did not waive fees and/or reimburse expenses during the period under this expense limitation.

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. For the six months ended August 31, 2012, expenses incurred under this agreement are shown in the Statement of Operations as Administrative services fees.

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.

18 Invesco Quality Municipal Securities


	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 August 31, 2012. 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.


	Level 1		Level 2		Level 3		Total

Municipal Obligations	$	—	$	312,739,580	$	—	$	312,739,580

NOTE 4—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 Trusts 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.

NOTE 5—Cash Balances

The Trust is permitted to temporarily carry a negative or overdrawn balance in its account with State Street Bank and Trust Company, the custodian bank. Such balances, if any at period end, are shown in the Statement of Assets and Liabilities under the payable caption Amount due custodian. 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 from 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 six months ended August 31, 2012 were $52,535,714 and 0.79%, respectively.

NOTE 6—Tax Information

The amount and character of income and gains to be distributed are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Reclassifications are made to the Trust’s capital accounts to reflect income and gains available for distribution (or available capital loss carryforward) under income tax regulations. The tax character of distributions paid during the year and the tax components of net assets will be reported at the Trust’s fiscal year-end.

Capital loss carryforward is calculated and reported as of a specific date. Results of transactions and other activity after that date may affect the amount of capital loss carryforward actually available for the Trust to utilize. The Regulated Investment Company Modernization Act of 2010 (the “Act”) eliminated the eight-year carryover period for capital losses that arise in taxable years beginning after its enactment date of December 22, 2010. Consequently, these capital losses can be carried forward for an unlimited period. However, capital losses with an expiration period may not be used to offset capital gains until all net capital losses without an expiration date have been utilized. Additionally, post-enactment capital loss carryovers will retain their character as either short-term or long-term capital losses instead of as short-term capital losses as under prior law. 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 had a capital loss carryforward as of February 29, 2012 which expires as follows:


Capital Loss Carryforward*

NOTE 8—Auction Rate Preferred Shares

The Trust is authorized to issue Auction Rate Preferred Shares (“ARPS”). From June 19, 2012 through June 21, 2012, the Trust redeemed all of its outstanding ARPS at their respective liquidation preference, including accrued and unpaid dividends, if any, through the redemption date. The redemptions were funded with proceeds received from the issuance of VMTP Shares.

Historically, the Trust paid annual fees equivalent to 0.25% of the ARPS liquidation value for the remarketing efforts associated with the auction. Effective March 31, 2009, the Trust decreased this amount to 0.15% due to auction failures. These fees are included as a component of Interest, facilities and maintenance fees on the Statement of Operations.

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

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

Beginning February 14, 2008 and continuing through June 21, 2012, all series of ARPS of the Trust were not successfully remarketed. As a result, the dividend rates of these ARPS were reset to the maximum applicable rate.

Transactions in ARPS were as follows:

NOTE 9—Variable Rate Muni Term Preferred Shares

On May 17, 2012, the Trust issued 453 Series 2015/12-IQM VMTP Shares, with liquidation preference of $100,000 per share pursuant to an offering exempt from registration under the Securities Act of 1933, as amended. Proceeds from the issuance of VMTP Shares were used to redeem all of the Trust’s outstanding ARPS. VMTP Shares are a floating-rate form of preferred shares with a mandatory redemption date. The Trust is required to redeem all outstanding VMTP Shares on December 1, 2015, unless earlier redeemed, repurchased or extended. VMTP Shares are subject to optional and mandatory redemption in certain circumstances. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends and a redemption premium, if any.

The Trust incurred costs in connection with the issuance of VMTP Shares. These costs were recorded as a deferred charge and will be amortized over the 3.5 year life of the VMTP Shares. Amortization of these costs is included in Interest, facilities and maintenance fees on the Statement of Operations and the unamortized balance is included in Deferred offering costs on the Statement of Assets and Liabilities.

Dividends paid on the VMTP Shares (which are treated as interest expense for financial reporting purposes) are declared daily and paid monthly. The initial rate for dividends is equal to the sum of 1.15% per annum plus the Securities Industry and Financial Markets Association Municipal Swap Index. Subsequent rates take into account a ratings spread which is based on the long term preferred share ratings assigned to the VMTP Shares by Moody’s and Fitch. The average liquidation value outstanding and the average annualized dividend rate of the VMTP Shares during the six months ended August 31, 2012 were $45,300,000 and 1.32%, respectively.

20 Invesco Quality Municipal Securities

The Trust is subject to certain restrictions, such as maintaining certain asset coverage and leverage ratio requirements relating to the VMTP Shares. Failure to comply with these restrictions could preclude the Trust from declaring any distributions to common shareholders or purchasing common shares and/or could trigger the mandatory redemption of VMTP Shares at liquidation value.

For financial reporting purposes, the liquidation value of VMTP Shares, which is considered debt of the issuer, is recorded as a liability under the caption Variable rate muni term preferred shares on the Statement of Assets and Liabilities. Unpaid dividends on VMTP Shares are recognized as Accrued interest expense on the Statement of Assets and Liabilities. Dividends paid on VMTP Shares are recognized as a component of Interest, facilities and maintenance fees on the Statement of Operations.

Approval of Investment Advisory and Sub-Advisory Contracts

The Board of Trustees (the Board) of Invesco Quality Municipal Securities (the Fund) is required under the Investment Company Act of 1940, as amended, to approve annually the renewal of the Fund’s investment advisory agreement with Invesco Advisers, Inc. (Invesco Advisers) and the Master Intergroup Sub-Advisory Contract for Mutual Funds (the sub-advisory contracts) with Invesco Asset Management Deutschland GmbH, Invesco Asset Management Limited, Invesco Asset Management (Japan) Limited, Invesco Australia Limited, Invesco Hong Kong Limited, Invesco Senior Secured Management, Inc. and Invesco Canada Ltd. (collectively, the Affiliated Sub-Advisers). During contract renewal meetings held on June 19-20, 2012, the Board as a whole, and the disinterested or “independent” Trustees, who comprise 80% of the Board, voting separately, approved the continuance of the Fund’s investment advisory agreement and the sub-advisory contracts for another year, effective July 1, 2012. In doing so, the Board considered the process that it follows in reviewing and approving the Fund’s investment advisory agreement and sub-advisory contracts and the information that it is provided. The Board determined that the Fund’s investment advisory agreement and the sub-advisory contracts are in the best interests of the Fund and its shareholders and the compensation to Invesco Advisers and the Affiliated Sub-Advisers under the agreements is fair and reasonable.

The Board’s Fund Evaluation Process

The Board’s Investments Committee has established three Sub-Committees, each of which is primarily responsible for overseeing the management of a number of the closed-end funds and all of the open-end funds advised by Invesco Advisers (the Invesco Funds). The Sub-Committees meet throughout the year to review the performance of their assigned funds, including reviewing materials prepared under the direction of the independent Senior Officer, an officer of the Invesco Funds who reports directly to the independent Trustees. Over the course of each year, the Sub-Committees meet with portfolio managers for their assigned Invesco Funds and other members of management to review the performance, investment objective(s), policies, strategies, limitations and investment risks of these funds. The Sub-Committees meet regularly and at designated contract renewal meetings each year to conduct a review of the performance, fees, expenses and other matters related to their assigned Invesco Funds. Each Sub-Committee recommends to the Investments Committee, which in turn recommends to the full Board, whether and on what terms to approve the continuance of each Invesco Fund’s investment advisory agreement and sub-advisory contracts for another year.

During the contract renewal process, the Trustees receive comparative performance and fee data regarding the Invesco Funds prepared by Invesco Advisers and an independent company, Lipper Inc. (Lipper). The Trustees also receive an independent written evaluation from the Senior Officer. The Senior Officer’s evaluation is prepared as part of his responsibility to manage the process by which the Invesco Funds’ proposed management fees are negotiated during the annual contract renewal process to ensure they are negotiated in a manner that is at arms’ length and reasonable. The independent Trustees are assisted in their annual evaluation of the Fund’s investment advisory agreement by the Senior Officer and by independent legal counsel. In addition to meetings with Invesco Advisers and fund counsel, the independent Trustees also discuss the continuance of the investment advisory agreement and sub-advisory contracts in private sessions with the Senior Officer and independent legal counsel.

In evaluating the fairness and reasonableness of the Fund’s investment advisory agreement and sub-advisory contracts, the Board considered, among other things, the factors discussed below. The Trustees also considered information provided in connection with fund mergers approved by the Trustees. The Trustees recognized that the advisory fees for the Invesco Funds include advisory fees that are the result of years of review and negotiation between the Trustees and Invesco Advisers as well as advisory fees previously approved by a different board that, at the time, was responsible for overseeing Morgan Stanley funds, which have become Invesco Funds following the acquisition of the retail mutual fund business of Morgan Stanley. The Trustees’ deliberations and conclusions in a particular year may be based in part on their deliberations and conclusions regarding these same arrangements throughout the year and in prior years. One Trustee may have weighed a particular piece of information or factor differently than another Trustee.

The discussion below serves as the Senior Officer’s independent written evaluation with respect to the Fund’s investment advisory agreement as well as a discussion of the material factors and related conclusions that formed the basis for the Board’s approval of the Fund’s investment advisory agreement and sub-advisory contracts. Unless otherwise stated, this information is current as of June 20, 2012, and may not reflect consideration of factors that became known to the Board after that date, including, for example, changes to the Fund’s performance, advisory fees, expense limitations and/or fee waivers.

Factors and Conclusions and Summary of Independent Written Fee Evaluation


A.	Nature, Extent and Quality of Services Provided by Invesco Advisers and the Affiliated Sub-Advisers

The Board reviewed the advisory services provided to the Fund by Invesco Advisers under the Fund’s investment advisory agreement, the performance of Invesco Advisers in providing these services, and the credentials and experience of the officers and employees of Invesco Advisers who provide these services, including the Fund’s portfolio manager or managers, with whom the Sub-Committees met during the year. The Board’s review of the qualifications of Invesco Advisers to provide advisory services included the Board’s consideration of Invesco Advisers’ performance and investment process oversight, independent credit analysis and investment risk management.

In determining whether to continue the Fund’s investment advisory agreement, the Board considered the prior relationship between Invesco Advisers and the Fund, as well as the Board’s knowledge of Invesco Advisers’ operations, and concluded that it is beneficial to maintain the current relationship, in part because of such prior relationship and knowledge. The Board also considered services that Invesco Advisers and its affiliates provide to the Invesco Funds such as various back office support functions, equity and fixed income trading operations, internal audit, and legal and compliance. The Board concluded that the nature, extent and quality of the services provided to the Fund by Invesco Advisers are appropriate and satisfactory and consistent with the terms of the Fund’s investment advisory agreement.

The Board reviewed the services provided by the Affiliated Sub-Advisers under the sub-advisory contracts and the credentials and experience of the officers and employees of the Affiliated Sub-Advisers who provide these services. The Board concluded that the sub-advisory contracts benefit the Fund and its shareholders by permitting Invesco Advisers to use the resources and talents of the Affiliated Sub-Advisers in managing the Fund. The Board concluded that the nature, extent and quality of the services provided by the Affiliated Sub-Advisers are appropriate and satisfactory and consistent with the terms of the Fund’s sub-advisory contracts.


B.	Fund Performance

The Board considered Fund performance as a relevant factor in considering whether to approve the investment advisory agreement. The Board did not view Fund performance as a relevant factor in considering whether to approve the sub-advisory contracts for the Fund, as no Affiliated Sub-Adviser currently manages assets of the Fund.

The Board compared the Fund’s performance during the past one, three and five calendar years to the performance of funds in the Lipper performance universe and against the Lipper Closed-End — General & Insured Municipal Funds (Leveraged) Index. The Board noted that the Fund’s performance was in the fourth quintile of its performance universe for the one, three and five year periods (the first quintile being the best performing funds and the fifth quintile being the worst performing funds). The Board noted that the

24 Invesco Quality Municipal Securities

Fund’s performance was below the performance of the Index for the one, three and five year periods. The Trustees also reviewed more recent Fund performance and this review did not change their conclusions.


C.	Advisory and Sub-Advisory Fees and Fee Waivers

The Board compared the Fund’s contractual advisory fee rate to the contractual advisory fee rates of funds in the Fund’s Lipper expense group at a common asset level. The Board noted that the Fund’s contractual advisory fee rate was below the median contractual advisory fee rate of funds in its expense group. The Board also reviewed the methodology used by Lipper in providing expense group information, which includes using audited financial data from the most recent annual report of each fund in the expense group that was publicly available as of the end of the past calendar year and including only one fund per investment adviser. The Board noted that comparative data is as of varying dates, which may affect the comparability of data during times of market volatility.

The Board also compared the Fund’s effective fee rate (the advisory fee after advisory fee waivers and before expense limitations/waivers) to the advisory fee rates of other closed-end funds advised by Invesco Advisers and its affiliates with investment strategies comparable to those of the Fund. The Board noted that the Fund’s rate was below the rates of ten closed-end funds and the same as the rates of two closed-end funds with comparable investment strategies.

Other than the funds described above, the Board noted that Invesco Advisers and the Affiliated Sub-Advisers do not manage other funds or client accounts in a manner substantially similar to the management of the Fund.

The Board also considered the services provided by the Affiliated Sub-Advisers pursuant to the sub-advisory contracts, as well as the allocation of fees between Invesco Advisers and the Affiliated Sub-Advisers pursuant to the sub-advisory contracts. The Board noted that Invesco Advisers provides services to sub-advised Invesco Funds, including oversight of the Affiliated Sub-Advisers as well as the additional services described above other than day-to-day portfolio management. The Board also noted that the sub-advisory fees have no direct effect on the Fund or its shareholders, as they are paid by Invesco Advisers to the Affiliated Sub-Advisers.

Based upon the information and considerations described above, the Board concluded that the Fund’s advisory and sub-advisory fees are fair and reasonable.


D.	Economies of Scale

The Board noted that most closed-end funds do not have fund level breakpoints because closed-end funds generally do not experience substantial asset growth after the initial public offering. The Board noted that although the Fund does not benefit from economies of scale through contractual breakpoints, the Fund shares directly in economies of scale through lower fees charged by third party service providers based on the combined size of the Invesco Funds and other clients advised by Invesco Advisers. The Board noted that Invesco Advisers proposes sharing economies of scale in administration expenses by lowering per class administrative fees.


E.	Profitability and Financial Resources

The Board reviewed information from Invesco Advisers concerning the costs of the advisory and other services that Invesco Advisers and its affiliates provide to the Fund and the profitability of Invesco Advisers and its affiliates in providing these services for the year ended December 31, 2011. The Board reviewed with Invesco Advisers the methodology used to prepare the profitability information. The Board considered the profitability of Invesco Advisers in connection with managing the Fund and the Invesco Funds. The Board noted that Invesco Advisers continues to operate at a net profit from services Invesco Advisers and its subsidiaries provide to the Invesco Funds and the Fund. The Board did not deem the level of profits realized by Invesco Advisers and its affiliates from providing services to the Fund to be excessive given the nature, quality and extent of the services provided to the Invesco Funds. The Board received and accepted information from Invesco Advisers demonstrating that Invesco Advisers and each Affiliated Sub-Adviser are financially sound and have the resources necessary to perform their obligations under the investment advisory agreement and sub-advisory contracts.


F.	Collateral Benefits to Invesco Advisers and its Affiliates

The Board considered various other benefits received by Invesco Advisers and its affiliates from the relationship with the Fund, including the fees received for their provision of administrative, transfer agency and distribution services to the Fund. The Board considered the performance of Invesco Advisers and its affiliates in providing these services and the organizational structure employed to provide these services. The Board also considered that these services are provided to the Fund pursuant to written contracts that are reviewed and approved on an annual basis by the Board; that the services are required for the operation of the Fund; that Invesco Advisers and its affiliates can provide services, the nature and quality of which are at least equal to those provided by others offering the same or similar services; and that the fees for such services are fair and reasonable in light of the usual and customary charges by others for services of the same nature and quality.

The Board considered the benefits realized by Invesco Advisers and the Affiliated Sub-Advisers as a result of portfolio brokerage transactions executed through “soft dollar” arrangements. Invesco Advisers noted that the Fund does not execute brokerage transactions through “soft dollar” arrangements to any significant degree.

The Board considered that the Fund’s uninvested cash and cash collateral from any securities lending arrangements may be invested in money market funds advised by Invesco Advisers pursuant to procedures approved by the Board. The Board noted that Invesco Advisers receives advisory fees from these affiliated money market funds attributable to such investments, although Invesco Advisers has contractually agreed to waive through varying periods the advisory fees payable by the Invesco Funds. The waiver is in an amount equal to 100% of the net advisory fee Invesco Advisers receives from the affiliated money market funds with respect to the Fund’s investment in the affiliated money market funds of uninvested cash, but not cash collateral. The Board concluded that the Fund’s investment of uninvested cash and cash collateral from any securities lending arrangements in the affiliated money market funds is in the best interests of the Fund and its shareholders.
