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:

Expense Example - Class A, B, C, Y And Investor Invesco High Yield Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	562	770	995	1,642
Class B	667	842	1,143	1,865
Class C	267	542	943	2,063
Class Y	65	231	411	931
Investor Class	88	300	530	1,190

You would pay the following expenses if you did not redeem your shares:

Expense Example, No Redemption - Class A, B, C, Y And Investor Invesco High Yield Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Class A	562	770	995	1,642
Class B	167	542	943	1,865
Class C	167	542	943	2,063
Class Y	65	231	411	931
Investor Class	88	300	530	1,190

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 65% 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 debt securities that are determined to be below investment grade quality.

          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 considers debt securities to be below investment grade quality if they are rated BB/Ba or lower by Standard & Poor’s Ratings Services, Moody’s Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are determined by the portfolio managers to be of comparable quality to such rated securities. These types of securities are commonly known as “junk bonds.” The Fund will principally invest in junk bonds rated B or above by an NRSRO or deemed to be of comparable quality by the portfolio managers.

          The Fund may invest up to 25% of its total assets in foreign securities. The Fund may also invest in securities, whether or not considered foreign securities, which carry foreign credit exposure. The Fund may also invest up to 15% of its total assets in securities of issuers located in developing markets.

          In selecting securities for the Fund’s portfolio, the portfolio managers focus on junk bonds that they believe have favorable prospects for high current income and the possibility of growth of capital. Before purchasing securities for the Fund, the portfolio managers conduct a bottom-up fundamental analysis of an issuer that involves an evaluation by a team of credit analysts of an issuer’s financial condition. The fundamental analysis is supplemented by (i) an ongoing review of the securities’ relative value compared with other junk bonds, and (ii) a top-down analysis of sector and macro-economic trends.

          The portfolio managers attempt to control the Fund’s risk by (i) limiting the portfolio’s assets that are invested in any one security, and (ii) diversifying the portfolio’s holdings over a number of different industries. The portfolio managers will consider selling a security if (1) there appears to be deterioration in a security’s risk profile, or (2) they determine that other securities offer better value.

          The Fund can invest in derivative instruments, specifically forward currency contracts, to mitigate the risk of foreign currency exposure, and credit default swaps and credit default swap indexes, to gain or reduce exposure to an asset class or a particular issuer.

          A forward currency contract is an agreement between parties to exchange a specified amount of currency at a specified future time at a specified rate. Forward currency contracts are used to protect against uncertainty in the level of future currency exchange rates or to gain or modify exposure to a particular currency. The Fund can use these contracts to hedge against adverse movements in the foreign currencies in which portfolio securities are denominated.

          A credit default swap is an agreement between two parties where the first party agrees to make one or more payments to the second party, while the second party assumes the risk of certain defaults. The Fund can enter into credit default swaps to create long or short exposure to corporate or sovereign debt securities. The Fund can buy a credit default swap (buy credit protection) or sell a credit default swap (sell credit protection). When the Fund buys a credit default swap it makes a stream of payments based on a fixed interest rate (the premium) over the life of the swap in exchange for a counterparty (the seller) taking on the risk of default of a reference debt obligation. Alternatively, the Fund can sell a credit default swap whereby the Fund can receive premium payments from the buyer in exchange for taking the risk of default of the underlying reference obligation.

          The Fund can invest in credit default swap indices which are credit derivatives used to hedge credit risk or take a position on a basket of credit entities. Credit default swap indices allow an investor to gain or reduce exposure on a basket of credit entities in a more efficient manner than transacting in single name credit default swaps. Unlike a credit default swap, a credit default swap index is a standardized credit security and therefore may be more liquid.

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:

          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.

          Derivatives Risk. The performance of derivative instruments is tied to the performance of an underlying currency, security, index or other instrument. In addition to risks relating to their underlying instruments, 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, leverage, correlation, liquidity, tax, market, interest rate and management risks. 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. Investors should bear in mind that, while the Fund intends to use derivative strategies, it is not obligated to actively engage in these transactions, generally or in any particular kind of derivative, if the investment manager elects not to do so due to availability, cost, market conditions or other factors.

          Developing/Emerging Markets Securities Risk. Securities issued by foreign companies and governments located in developing/emerging countries may be affected more negatively by inflation, devaluation of their currencies, higher transaction costs, delays in settlement, adverse political developments, the introduction of capital controls, withholding taxes, nationalization of private assets, expropriation, social unrest, war or lack of timely information than those in developed countries.

          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.

          High Yield Bond (Junk Bond) Risk. Junk bonds involve a greater risk of default or price changes due to changes in the credit quality of the issuer. The values of junk bonds fluctuate more than those of high-quality bonds in response to company, political, regulatory or economic developments. Values of junk bonds can decline significantly over short periods of time.

          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.

          Reinvestment Risk. Reinvestment risk is the risk that a bond’s cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond.

          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.
