Fees and Expenses of the Fund This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Shareholder Fees (fees paid directly from your investment) 0 0 0 0 Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.007 0.007 0 0 0.0015 0.0007 0.0085 0.0077 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: 87 79 271 246 471 428 1049 954 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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 109% of the average value of its portfolio. 1.09 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 objective by investing primarily in common stocks and other equity securities of medium-sized growth companies. Under normal market conditions, the Fund invests at least 80% of its net assets (including any borrowings for investment purposes) in securities of medium-sized companies at the time of investment. In complying with the 80% investment requirement, the Fund may include synthetic securities that have economic characteristics similar to the Fund’s direct investments that are counted toward the 80% investment requirement. The Fund may invest up to 25% of its total assets in securities of foreign issuers and may invest up to 10% of its total assets in real estate investment trusts (REITs). In attempting to meet its investment objective, the Fund engages in active and frequent trading of portfolio securities. The Adviser uses a bottom-up stock selection process designed to seek returns in excess of the benchmark as well as a disciplined portfolio construction process designed to manage risk. To narrow the investment universe, the Adviser uses a holistic approach that emphasizes fundamental research and, to a lesser extent, includes quantitative analysis. The Adviser then closely examines company fundamentals, including detailed modeling of all of a company’s financial statements and discussions with company management teams, suppliers, distributors, competitors, and customers. The Adviser uses a variety of valuation techniques based on the company in question, the industry in which the company operates, the stage of the business cycle, and other factors that best reflect a company’s value. The Adviser seeks to invest in companies with solid management teams, sound business models, strong financial health, attractive growth outlooks, and compelling valuations levels. The Adviser considers whether to sell a particular security when a company hits the price target, a company’s fundamentals deteriorate, or the catalysts for growth are no longer present or reflected in the stock price. Principal Risks of Investing in the Fund As with any mutual fund, 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: Active Trading Risk. The Fund engages in frequent trading of portfolio securities. Active trading results in added expenses and may result in a lower return and increased tax liability. 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. Risks of Medium-Sized Companies. Medium-sized companies often have less predictable earnings, more limited product lines, markets, distribution channels or financial resources and the management of such companies may be dependent upon one or few key people. The market movements of equity securities of medium-sized companies may be more abrupt and volatile than the market movements of equity securities of larger, more established companies or the stock market in general. Historically, medium-sized companies have sometimes gone through extended periods when they did not perform as well as larger companies. In addition, equity securities of medium-sized companies generally are less liquid than larger companies. This means that the Fund could have greater difficulty selling such securities at the time and price that the Fund would like. Growth Investing Risk. Investments in growth-oriented equity securities may have above-average volatility of price movement. The returns on growth securities may or may not move in tandem with the returns on other styles of investing or the overall stock markets. Different types of stocks tend to shift in and out of favor depending on market and economic conditions. Thus, the value of the Fund’s investments will vary and at times may be lower or higher than that of other types of investments. 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 securities regulation and trading, and foreign taxation issues. Risks of Investing in REITs. Investing in REITs makes the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general and may involve duplication of management fees and other expenses. REITs may be less diversified than other pools of securities, may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. Synthetic Securities Risk. Fluctuations in the values of synthetic securities may not correlate perfectly with the instruments they are designed to replicate. Synthetic securities may be subject to interest rate changes, market price fluctuations, counterparty risk and liquidity risk. 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. As with any mutual fund, loss of money is a risk of investing. 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 the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and Van Kampen Mid Cap Growth Fund’s (the predecessor fund) 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 Class R5 shown prior to June 1, 2010 are those of the Class A shares of the predecessor fund. Class R6 shares of the Fund have less than a calendar year of performance; therefore, the returns shown are those of the Fund’s (and the predecessor Fund’s) Class A shares, which are not offered in this prospectus. Class R5 and Class R6 shares would have different returns from the predecessor fund because, although the shares are invested in the same portfolio of securities, Class R5 and Class R6 shares have different expenses. The predecessor fund was advised by Van Kampen Asset Management. Updated performance information is available on the Fund’s Web site at www.invesco.com/us.
