Invesco believes that sustainable dividend income and capital appreciation potential are important to total return expectations. Corporate managers use stable and increasing dividends as a sign of confidence in their firm’s prospects, while investors may consider such track records as signs of corporate maturity and strength.1

Companies with strong dividend coverage should be able to increase dividend payments.1

Portfolio Composition1

ObjectiveThe portfolio seeks above-average capital appreciation. The portfolio seeks to achieve its objective by investing in a portfolio of stocks derived from the S&P 500 Dividend Aristocrats Index. The S&P 500 Dividend Aristocrats Index consists of stocks of those companies in the S&P 500 Index that have increased their actual dividend payments in each of the last 25 years.

1 The trust portfolio is provided for informational purposes only and should not be deemed as a recommendation to buy or sell the individual securities shown above.

2 Including sales charges. As of deposit date.3 Represents the value of 100 units on the deposit date. The value of the minimum investment amount of 100 units may be

greater or less than $1,000 following the deposit date.4 The estimated Net Annual Income per unit is as of April 30, 2013, and is based on the most recently declared quarterly

dividends, interim and final dividends accounting for any foreign withholding taxes or scheduled income payments, but may also be based upon several recently declared dividends. The actual net annual income distributions you receive will vary from the estimate set forth above with changes in the trust’s fees and expenses, in income received, currency fluctuations and with the call, maturity or sale of securities. The actual net annual distributions are expected to decrease over time because a portion of the securities included in the trust will be sold to pay for organization costs, deferred sales charges and the creation and development fee. Securities may also be sold to pay regular fees and expenses during the trust’s life.

5 Funds will typically be mailed within three business days after your redemption request is received.

S&P Capital IQ Quality Rankings reflect the long-term growth and stability of a company’s earnings and dividends in a range from A+ (highest) to C (lowest), with a ranking of D reflecting in reorganization and LIQ represents liquidation. See standardandpoors.com for additional information. A credit rating is an assessment provided by a nationally recognized statistical rating organization (NRSRO) of the creditworthiness of an issuer with respect to debt obligations, including specific securities, money market instruments or other debts. Ratings are measured on a scale that generally ranges from AAA (highest) to D (lowest); ratings are subject to change without notice. For more information on Standard & Poor’s rating methodology, please visit standardandpoors.com and select “Understanding Ratings” under Ratings on the homepage.

The opinions expressed are based on current market conditions and are subject to change without notice. These opinions may differ from those of other Invesco investment. The S&P 500 Index is an unmanaged index generally representative of the US stock market and consists of 500 large-cap common stocks actively traded in the United States. The S&P 500 Dividend Aristocrats Index is an index composed of 40 companies in the S&P 500 Index that have had an increase in dividends for 25 consecutive years. The S&P 500 Dividend Aristocrats Index tracks the performance of these companies. A dividend aristocrat tends to be a large blue-chip company. Indices are statistical composites and their returns do not include payment of any sales charges or fees an investor would pay to purchase the securities they represent. Such costs would lower performance. It is not possible to invest directly in an index. The Morningstar Equity Style Box™ is based on April 30, 2013, data. The Morningstar Style Box™ reveals a fund’s investment strategy. For equity funds, the vertical axis shows the market capitalization of the stocks owned, and the horizontal axis shows investment style (value, blend or growth). For fixed income funds, the vertical axis shows the average credit quality of the bonds owned, and the horizontal axis shows interest rate sensitivity as measured by a bond’s duration (short, intermediate or long). Value, blend and growth are types of investment styles. Growth investing generally seeks stocks that offer the potential for greater-than-average earnings growth, and may entail greater risk than value or blend investing. Value investing generally seeks stocks that may be sound investments but are temporarily out of favor in the marketplace, and may entail less risk than growth investing. A blend investment combines the two styles.

Risk considerationsThere is no assurance the trust will achieve its investment objective. An investment in this unit investment trust is subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of trust units may therefore be less than what you paid for them. This trust is unmanaged and its portfolio is not intended to change during the trust’s life except in limited circumstances. Accordingly, you can lose money investing in this trust. Common stocks do not assure dividend payments. Dividends are paid only when declared by an issuer’s board of directors and the amount of any dividend may vary over time. The portfolio is concentrated in both the consumer discretionary sector and the consumer staples sectors. Companies that manufacture, distribute and provide consumer products and services face risks such as intense competition, the lack of serious barriers to entry for online entrants, economic recession and a slowdown in consumer spending trends.

Before investing, investors should carefully read the prospectus and consider the investment objectives, risks, charges and expenses. For this and more complete information about the trust, investors should ask their advisor(s) for a prospectus or download one at invesco.com/unittrust.
