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 the same. 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 commissions, 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. The portfolio turnover rate of the Van Kampen Real Estate Securities Fund (the predecessor fund) and the Fund for the most recent fiscal year was 86% of the average value of the portfolio.
Principal Investment Strategies of the Fund

Under normal market conditions, Invesco Advisers, Inc. (the Adviser), the Fund’s investment adviser, seeks to achieve the Fund’s investment objectives by investing primarily in a portfolio of securities of companies operating in the real estate industry, including equity securities of real estate investment trusts (REITs) and other securities of real estate operating companies. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities of companies operating in the real estate industry, including equity securities of REITs and other securities of real estate operating companies at the time of investment. A company operating in the real estate industry is one that derives at least 50% of its assets, gross income or net profits from the ownership, construction, management or sale of residential, commercial or industrial real estate. Besides equity securities of REITs, the Fund may invest in equity securities, including common stocks and convertible securities, or non-convertible preferred stocks and investment-grade debt securities of companies operating in the real estate industry. The Fund may invest up to 20% of the Fund’s net assets in securities of companies outside the real estate industry. The Fund may invest up to 25% of its total assets in securities of foreign issuers, some or all of which may be in the real estate industry. The Fund may purchase and sell options, futures contracts and options on futures contracts, which are derivative instruments, for various portfolio management purposes, including to earn income, to facilitate portfolio management and to mitigate risks. In general terms, a derivative instrument is one whose value depends on (or is derived from) the value of an underlying asset, interest rate or index.

When constructing the portfolio, the portfolio managers use a fundamentals driven investment process, including an evaluation of factors such as real property market cycle analysis, real property evaluation and management and structure review to identify securities with characteristics including (i) quality underlying properties, (ii) solid management teams with the ability to effectively manage capital structure decisions, and (iii) attractive valuations relative to peer investment alternatives.

The portfolio managers and investment team focus on equity REITs and real estate operating issuers. Some of the fundamental factors that are evaluated in screening potential investments for the Fund include: forecasted occupancy and rental rates of the various property markets in which a firm may operate, property locations, physical attributes and cash flow generating capacity of an issuer’s properties and calculating relative return potential, asset quality, management depth and skill, insider ownership, overall debt levels, percentage of variable rate financing and fixed charge coverage ratios. The issuers that are believed to have the most attractive fundamental attributes are then screened according to pricing factors that allow the management team to assess security valuations relative to one another and relative to the investment teams’ assessment of underlying asset value. The portfolio managers also consider the relative liquidity of each security in the construction of the Fund.

The portfolio managers seek to construct a portfolio with risk characteristics similar to the FTSE NAREIT Equity All REITs Index (the benchmark index). The Fund seeks to limit risk through various controls, such as diversifying the portfolio property types and geographic areas as well as by limiting the size of any one holding. Various factors may lead to overweighting or underweighting of particular property types and/or geographic areas from time to time.

The portfolio managers will consider selling a security if they conclude (1) its relative valuation falls below desired levels, (2) its risk/return profile changes significantly, (3) its fundamentals change, or (4) a more attractive investment opportunity is identified.

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 government 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:

Market Risk. Market risk is the possibility that the market values of securities owned by the Fund will decline. Market risk may affect a single issuer, industry, sector of the economy or the market as a whole. Investments in equity securities generally are affected by changes in the stock markets, which fluctuate substantially over time, sometimes suddenly and sharply. The prices of equity securities of companies in the real estate industry may be more volatile and may not fluctuate in tandem with overall changes in the stock markets. Investments in fixed income or debt securities generally are affected by changes in interest rates and creditworthiness of the issuer. The prices of fixed income or debt securities tend to fall as interest rates rise, and such declines tend to be greater among securities with longer maturities.

Risks of Investing in Real Estate. The risks of investing in real estate can include fluctuations in the value of underlying properties; defaults by borrowers or tenants; market saturation; changes in general and local economic conditions; decreases in market rates for rents; increases in competition, property taxes, capital expenditures, or operating expenses; and other economic, political or regulatory occurrences affecting the real estate industry. In addition, REITs depend upon specialized management skills, may not be diversified, may have less trading volume, and may be subject to more abrupt or erratic price movements than the overall securities markets. REITs must comply with certain requirements of the federal income tax law to maintain their federal income tax status. Some REITs (especially mortgage REITs) are affected by risks similar to those associated with investments in debt securities including changes in interest rates and the quality of credit extended. Investments in REITs may involve duplication of management fees and certain other expenses.

Concentration Risk. Because the Fund concentrates in investments in the real estate industry, the value of your shares may rise and fall more than the value of share of a fund that invests in companies in a broader range of industries.

Foreign Risks. The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, foreign currency exchange controls, political and economic instability, differences in financial reporting, differences in securities regulation and trading, and foreign taxation issues.

Non-Diversification Risks. The Fund may be subject to greater risk than a diversified fund because changes in the financial condition or market assessment of a single issuer may cause greater fluctuations in the value of the Fund’s shares.

Risks of Using Derivative Instruments. Risks of derivatives include imperfect correlation between the value of the instruments and the underlying assets; risks of default by the other party to certain transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the transactions may not be liquid.

Performance Information

The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in performance of the Fund from year to year as of December 31. The performance table compares the Fund’s performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to the Fund. The Fund’s (and the predecessor fund’s) past performance (before and after taxes) is not necessarily an indication of its future performance.

The returns for periods prior to June 1, 2010 are those of the Class A shares of the predecessor fund, which are not offered by the Fund. The predecessor fund was advised by Van Kampen Asset Management. Institutional Class shares’ returns of the Fund will be different from the predecessor fund as they have different expenses. Year-to-date returns include returns of the Fund for periods ending on or after June 1, 2010.

Updated performance information is available on the Fund’s Web site at www.invesco.com/us.
