Example. This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain equal to the Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement in the first year and the Total Annual Fund Operating Expenses thereafter.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover. The Fund pays transaction costs, such as commis-sions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 26% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity and income securities, and in derivatives and other instruments that have economic characteristics similar to such securities.

The Fund may invest in securities of issuers of all capitalization sizes; however, a substantial number of the issuers in which the Fund invests are large-capitalization issuers.

The Fund invests, under normal circumstances, at least 65% of its net assets in income-producing equity investments, such as dividend paying common or preferred stocks.

The Fund may invest in income-producing equity instruments (subject to the 65% policy above), debt securities and warrants or rights to acquire such securities, in such proportions as economic conditions indicate would best accomplish the Fund’s objectives. It is the current operating policy of the Fund to invest in debt securities rated investment grade. It is also the operating policy of the Fund to invest not more than 10% of its net assets in debt securities rated Baa by Moody’s Investors Service (Moody’s) or BBB by Standard & Poor’s Ratings Services (S&P), or in unrated securities determined by the Fund’s investment adviser, Invesco Advisers, Inc. (the Adviser), to be of comparable quality at the time of purchase. These operating policies do not apply to convertible securities, which are selected primarily on the basis of their equity characteristics.

The Fund may invest up to 15% of its net assets in real estate investment trusts (REITs).

The Fund may invest up to 25% of its net assets in securities of foreign issuers or depositary receipts.

The Fund can invest in derivative instruments including forward foreign currency contracts, futures contracts and options.

The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

The Fund can use futures contracts to seek exposure to certain asset classes and to hedge against adverse movements in the foreign curren-cies in which portfolio securities are denominated.

The Fund can use options to seek alpha (return on investments in excess of the Russell 1000» Value Index) or to mitigate risk and to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

(6)

operational enhancements, restructuring or reorganization. It could also be an external factor, such as an improvement in industry conditions or a regulatory change.

The Fund may dispose of a security when the security reaches the Adviser’s estimate of fair value or when the Adviser identifies a more attractive investment opportunity.

Principal Risks of Investing in the Fund

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are:

Call Risk. If interest rates fall, it is possible that issuers of debt

securities with high interest rates will prepay or call their securities before their maturity dates. In this event, the proceeds from the called securities would likely be reinvested by the Fund in securities bearing the new, lower interest rates, resulting in a possible decline in the Fund’s income and distributions to shareholders.

Convertible Securities Risk. The Fund may own convertible securities,

the value of which may be affected by market interest rates, the risk that the issuer will default, the value of the underlying stock or the right of the issuer to buy back the convertible securities.

Credit Risk. The issuer of instruments in which the Fund invests may

be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer’s credit rating.

Depositary Receipts Risk. Depositary receipts involve many of the same

risks as those associated with direct investment in foreign securities. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts or to pass through to them any voting rights with respect to the deposited securities.

Derivatives Risk. The performance of derivative instruments is tied to

the performance of an underlying currency, security, index, commodity or other asset. In addition to risks relating to their underlying assets, the use of derivatives may include other, possibly greater, risks. Derivatives involve costs, may be volatile, and may involve a small initial investment relative to the risk assumed. Risks associated with the use of derivatives may include counterparty, margin, leverage, correlation, liquidity, tax, market, interest rate and management risks, as well as the risk of potential increased regulation of derivatives. Derivatives may also be more difficult to purchase, sell or value than other investments. The Fund may lose more than the cash amount invested on investments in derivatives. Each of these risks is greater for the Fund than mutual funds that do not use derivatives to implement their investment strategy.

Equity Risk. Equity risk is the risk that the value of securities held by

the Fund will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate or factors relating to specific companies in which the Fund invests, either directly or through derivative instruments. For example, an adverse event, such as an unfavorable earnings report, may depress the value of securities held by the Fund; the price of securities may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the securities held by the Fund. In addition, securities of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition.

Foreign Securities Risk. The Fund’s foreign investments may be

affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility.

Foreign companies may be subject to less regulation resulting in less publicly available information about the companies.

Income Risk. The income you receive from the Fund is based primarily

on prevailing interest rates, which can vary widely over the short- and long-term. If interest rates drop, your income from the Fund may drop as well.

Interest Rate Risk. Interest rate risk refers to the risk that bond prices

generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration.

Management Risk. The investment techniques and risk analysis used

by the Fund’s portfolio managers may not produce the desired results.

Market Risk. The prices of and the income generated by the Fund’s

securities may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.

Preferred Securities Risk. There are special risks associated with

investing in preferred securities. Preferred securities may include provi-sions that permit the issuer, in its discretion, to defer or omit distributions for a certain period of time. If the Fund owns a security that is deferring or omitting its distributions, the Fund may be required to report the distribution on its tax returns, even though it may not have received this income. Further, preferred securities may lose substantial value due to the omission or deferment of dividend payments.

REIT Risk/Real Estate Risk. Investments in real estate related

instru-ments may be affected by economic, legal, cultural, environmental or technological factors that affect property values, rents or occupancies of real estate related to the Fund’s holdings. Real estate companies, including REITs or similar structures, tend to be small- and mid-cap companies, and their shares may be more volatile and less liquid. The value of investments in real estate related companies may be affected by the quality of management, the ability to repay loans, the utilization of leverage and financial covenants related thereto, whether the company carries adequate insurance and environmental factors. If a real estate related company defaults, the Fund may own real estate directly, which involves the following additional risks: environmental liabilities; difficulty in valuing and selling the real estate; and economic or regulatory changes.

Small- and Mid-Capitalization Risks. Stocks of small- and mid-sized

companies tend to be more vulnerable to adverse developments and may have little or no operating history or track record of success, and limited product lines, markets, management and financial resources. The securi-ties of small- and mid-sized companies may be more volatile due to less market interest and less publicly available information about the issuer. They also may be illiquid or restricted as to resale, or may trade less frequently and in smaller volumes, all of which may cause difficulty when establishing or closing a position at a desirable price.

Value Investing Style Risk. The Fund emphasizes a value style of

investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.

Tax Information

The Fund’s distributions generally are taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or individual retirement account, in which case your distributions generally will be taxed when withdrawn from the tax-deferred account.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and the Fund’s distributor or its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson or financial adviser to recommend the Fund over another investment. Ask your salesperson or financial adviser or visit your financial intermediary’s Web site for more information.

Investment Objective(s), Strategies,

Risks and Portfolio Holdings

Objective(s) and Strategies

The Fund’s investment objective is current income and, secondarily, capital appreciation. The Fund’s investment objective may be changed by the Board of Trustees (the Board) without shareholder approval.

The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity and income securities, and in derivatives and other instruments that have economic characteristics similar to such securities.

The Fund may invest in securities of issuers of all capitalization sizes; however, a substantial number of the issuers in which the Fund invests are large-capitalization issuers.

The Fund considers an issuer to be a large-capitalization issuer if it has a market capitalization, at the time of purchase, within the range of the largest and smallest capitalized companies included in the

(8)

month-end data) plus the most recent date during the current month. As of August 31, 2013, the capitalization of companies in the Russell 1000» Index ranged from $324 million to $442.6 billion.

The Fund invests, under normal circumstances, at least 65% of its net assets in income-producing equity investments. Income-producing equity investments are dividend paying common or preferred stocks, interest paying convertible debentures or bonds, or zero coupon convertible securities (on which the Fund accrues income for tax and accounting purposes, but receives no cash).

The Fund may invest in income-producing equity instruments (subject to the 65% policy above), debt securities and warrants or rights to acquire such securities, in such proportions as economic conditions indicate would best accomplish the Fund’s objectives. It is the current operating policy of the Fund to invest in debt securities rated investment grade. Investment grade securities are: (i) securities rated BBB- or higher by S&P or Baa3 or higher by Moody’s or an equivalent rating by another nationally recognized statistical rating organization (NRSRO), or (ii) unrated securities determined by the Adviser to be of comparable quality at the time of purchase. It is also the operating policy of the Fund to invest not more than 10% of its net assets in debt securities rated Baa by Moody’s or BBB by S&P, or in unrated securities determined by the Adviser to be of comparable quality at the time of purchase. These operating policies do not apply to convertible securities which are selected primarily on the basis of their equity characteristics.

The Fund may invest up to 15% of its net assets in REITs. REITs pool investors’ funds for investment primarily in commercial real estate properties or real-estate related loans. REITs generally derive their income from rents on the underlying properties or interest on the underlying loans, and their value is impacted by changes in the value of the underlying property or changes in interest rates affecting the underlying loans owned by the REITs.

The Fund may invest up to 25% of its net assets in securities of foreign issuers or depositary receipts. A depositary receipt is generally issued by a bank or financial institution and represents an ownership interest in the common stock or other equity securities of a foreign company.

The Fund can invest in derivative instruments including forward foreign currency contracts, futures contracts and options.

A forward foreign currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. The Fund can use forward foreign currency contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

A futures contract is a standardized agreement between two parties to buy or sell a specified quantity of an underlying asset at a specified price at a specified future time. The value of the futures contract tends to increase and decrease in tandem with the value of the underlying asset. Futures contracts are bilateral agreements, with both the purchaser and the seller equally obligated to complete the transaction. Depending on the terms of the particular contract, futures contracts are settled by purchas-ing an offsettpurchas-ing contract, physically deliverpurchas-ing the underlypurchas-ing asset on the settlement date or paying of a cash settlement amount on the settlement date. The Fund can use futures contracts to seek exposure to certain asset classes and to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

An option is a derivative financial instrument that represents a contract between two parties for a future transaction on an asset at a reference price. The buyer of the option gains the right, but not the obligation, to engage in that transaction, while the seller incurs the corresponding obligation to fulfill the transaction. The price of an option derives from the difference between the reference price and the value of the underlying asset (commonly a stock, a bond, a currency or a futures contract) plus a premium based on the time remaining until the expiration of the option. Other types of options exist, and options can in principle be created for any type of valuable asset. The Fund can use options to seek alpha

(return on investments in excess of the Russell 1000 Index) or to mitigate risk and to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

In selecting securities, the Adviser focuses on a security’s potential for income with safety of principal and long-term growth of capital. The Adviser emphasizes a value style of investing, which focuses on underval-ued companies with characteristics for improved valuations. This catalyst could come from within the company in the form of new management, operational enhancements, restructuring or reorganization. It could also be an external factor, such as an improvement in industry conditions or a regulatory change.

The Fund may dispose of a security when the security reaches the Adviser’s estimate of fair value or when the Adviser identifies a more attractive investment opportunity.

In anticipation of or in response to market, economic, political, or other conditions, the Fund’s portfolio managers may temporarily use a different investment strategy for defensive purposes. If the Fund’s portfolio manag-ers do so, different factors could affect the Fund’s performance and the Fund may not achieve its investment objective.

The Fund’s investments in the types of securities described in this prospectus vary from time to time, and, at any time, the Fund may not be invested in all of the types of securities described in this prospectus. The Fund may also invest in securities and other investments not described in this prospectus.

For more information, see “Description of the Funds and Their Invest-ments and Risks” in the Fund’s SAI.

Risks

The principal risks of investing in the Fund are:

Call Risk. If interest rates fall, it is possible that issuers of debt

securities with high interest rates will prepay or call their securities before their maturity dates. In this event, the proceeds from the called securities would likely be reinvested by the Fund in securities bearing the new, lower interest rates, resulting in a possible decline in the Fund’s income and distributions to shareholders.

Convertible Securities Risk. The values of convertible securities in

which the Fund may invest may be affected by market interest rates. The values of convertible securities also may be affected by the risk of actual issuer default on interest or principal payments and the value of the underlying stock. Additionally, an issuer may retain the right to buy back its convertible securities at a time and price unfavorable to the Fund.

Credit Risk. The issuers of instruments in which the Fund invests may

be unable to meet interest and/or principal payments. This risk is increased to the extent the Fund invests in junk bonds. An issuer’s securities may decrease in value if its financial strength weakens, which may reduce its credit rating and possibly its ability to meet its contractual obligations.

Depositary Receipts Risk. Depositary receipts involve many of the same

risks as those associated with direct investment in foreign securities. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts or to pass through to them any voting rights with respect to the deposited securities.

Derivatives Risk. The performance of derivative instruments is tied to

the performance of an underlying currency, security, index, commodity or other asset. In addition to risks relating to their underlying assets, the use of derivatives may include other, possibly greater, risks. Risks associated with the use of derivatives may include counterparty, margin, leverage, correlation, liquidity, tax, market, interest rate and management risks, as well as the risk of potential increased regulation of derivatives. Derivatives may also be more difficult to purchase, sell or value than other

(9)

mutual funds that do not use derivatives to implement their investment strategy.

mCounterparty Risk. Counterparty risk is the risk that a counterparty to

a derivative transaction will not fulfill its contractual obligations (including because of bankruptcy or insolvency) to make principal or interest payments to the Fund, when due, which may cause losses or additional costs to the Fund.

mMargin Risk. With respect to futures and certain swaps and options,

there is a risk of loss by the Fund of the initial and variation margin deposits in the event of bankruptcy of a futures commission merchant (FCM) with which the Fund has an open position in a futures, swaps or options contract. The assets of a Fund may not be fully protected in the event of the bankruptcy of the FCM or central counterparty. The Fund is also subject to the risk that the FCM could use the Fund’s assets to satisfy its own financial obligations or the payment obligations of another customer to the central counterparty.

mLeverage Risk. Leverage exists when the Fund purchases or sells a

derivative instrument or enters into a transaction without investing cash in an amount equal to the full economic exposure of the asset or transaction and the Fund could lose more than it invested. The Fund mitigates leverage risk by segregating or earmarking liquid assets or otherwise covering transactions that may give rise to such risk. Leverage may cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. The use of some derivative instru-ments may result in economic leverage, which does not result in the possibility of the Fund incurring obligations beyond its investment, but that nonetheless permits the Fund to gain exposure that is greater than would be the case in an unlevered instrument. The Fund does not segregate assets or otherwise cover investments in deriva-tives with economic leverage.

mCorrelation Risk. To the extent that the Fund uses derivatives for

hedging or reducing exposure, there is the risk of imperfect correla-tion between movements in the value of the derivative instrument and the value of an underlying asset, reference rate or index. To the extent that the Fund uses derivatives for hedging purposes, there is the risk during extreme market conditions that an instrument which would usually operate as a hedge provides no hedging benefits at all.

mLiquidity Risk. Liquidity risk is the risk that the Fund may be unable

to close out a derivative position because the trading market becomes illiquid or the availability of counterparties becomes limited for a period of time. To the extent that the Fund is unable to close out a derivative position because of market illiquidity, the Fund may not be able to prevent further losses of value in its derivatives holdings and the liquidity of the Fund’s other assets may be impaired to the extent that it has a substantial portion of its otherwise liquid assets marked as segregated to cover its obligations under such derivative instruments. The Fund may also be required to take or make delivery of an underlying asset that the Adviser would otherwise have attempted to avoid.

mTax Risk. The use of certain derivatives may cause the Fund to

realize higher amounts of ordinary income or short-term capital gain, distributions from which are taxable to individual shareholders at ordinary income tax rates rather than at the more favorable tax rates for long-term capital gain. The Fund’s use of derivatives may be limited by the requirements for taxation of the Fund as a regulated investment company. The tax treatment of derivatives may be affected by changes in legislation, regulations or other legal authority that could affect the character, timing and amount of the Fund’s taxable income or gains and distributions to shareholders.

mMarket Risk. Derivatives are subject to the market risks associated

with their underlying assets, which may decline in response to, among other things, investor sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations. Derivatives may be subject to heightened

and evolving government regulations, which could increase the costs of owning certain derivatives.

mInterest Rate Risk. Some derivatives are particularly sensitive to

interest rate risk, which is the risk that prices of fixed income instruments generally fall as interest rates rise; conversely, prices of fixed income instruments generally rise as interest rates fall. Specific fixed income instruments differ in their sensitivity to changes in interest rates depending on their individual characteristics.

mManagement Risk. The investment techniques and risk analysis used

by the Fund’s portfolio managers in connection with investing in derivatives may not produce the desired results.

mRisk of Potential Increased Regulation of Derivatives. The regulation

of derivatives is a rapidly changing area of law and is subject to modification by government and judicial action. It is not possible to predict fully the effects of current or future regulation. However, it is possible that developments in government regulation of various types of derivative instruments may limit or prevent a Fund from using or limit the Fund’s use of these instruments effectively as a part of its investment strategy, and could adversely affect the Fund’s ability to achieve its investment objective. New requirements, even if not directly applicable to the Fund, may increase the cost of the Fund’s investments and cost of doing business.

Equity Risk. Equity risk is the risk that the value of securities held by

the Fund will fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate or factors relating to specific companies in which the Fund invests, either directly or through derivative instruments. For example, an adverse event, such as an unfavorable earnings report, may depress the value of securities held by the Fund; the price of securities may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the securities held by the Fund. In addition, securities of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition.

Foreign Securities Risk. The dollar value of the Fund’s foreign

invest-ments may be affected by changes in the exchange rates between the dollar and the currencies in which those investments are traded. The value of the Fund’s foreign investments may be adversely affected by political and social instability in their home countries, by changes in economic or taxation policies in those countries, or by the difficulty in enforcing obligations in those countries. Foreign companies generally may be subject to less stringent regulations than U.S. companies, including financial reporting requirements and auditing and accounting controls. As a result, there generally is less publicly available information about foreign companies than about U.S. companies. Trading in many foreign securities may be less liquid and more volatile than U.S. securities due to the size of the market or other factors.

Income Risk. The income you receive from the Fund is based primarily

on prevailing interest rates, which can vary widely over the short- and long-term. If interest rates drop, your income from the Fund may drop as well.

Interest Rate Risk. Interest rate risk refers to the risk that bond prices

generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics. One measure of this sensitivity is called duration. The longer the duration of a particular bond, the greater is its price sensitivity is to interest rates. Similarly, a longer duration portfolio of securities has greater price sensitivity. Falling interest rates may also prompt some issuers to refinance existing debt, which could affect the Fund’s performance.

Management Risk. The investment techniques and risk analysis used

by the Fund’s portfolio managers may not produce the desired results.

Market Risk. The prices of and the income generated by the Fund’s

(10)

sentiment, general economic and market conditions, regional or global instability, and currency and interest rate fluctuations.
