Small Cap Strategy5 Outlined below is the selection process for each of the six different strategies that are combined to create the Enhanced Index Strategies Portfolio. Small Cap Growth Component 1. Eliminate stocks from the Russell 2000 Index with share prices of less than $5. 2. Rank remaining stocks by Earnings Pressure.SM 3. Select the 25 stocks with the highest Earnings Pressure.SM In addition, a stock will be excluded and such stock will be replaced with the stock with the next highest Earnings Pressure if, based on publicly available information as of the selection date, the company is the target of an announced business acquisition which Invesco expects will close within six months of the date of deposit. The Dow Contrarian Strategy Select the 10 stocks from the Dow Jones Industrial Average with the lowest percentage price change over the preceding 52-week period. Large Cap Growth Strategy 1. Eliminate stocks from the S&P 500 Index with share prices of less than $5. 2. The remaining stocks are ranked by price momentum and the 75 stocks with the highest price momentum are selected. (A comparison of current stock price versus historical stock prices). 3. Rank these 75 stocks by Earnings PressureSM 4, a proprietary measure developed by Lightstone Capital Management. 4. The strategy selects the 15 stocks with the highest Earnings Pressure, provided that no more than six stocks may be selected from any single industry (as defined by Zacks Investment Research), no more than two stocks may have a market capitalization of less than $5 billion dollars and provided that the stock of any affiliate of Invesco or any of its affiliates, will be excluded and replaced with the stock with the next highest Earnings Pressure. In addition, a stock will be excluded and such stock will be replaced with the stock with the next highest Earnings Pressure if, based on publicly available information as of the selection date, the company is the target of an announced business acquisition which Invesco expects will close within six months of the date of deposit. Small Cap Value Component 1. Eliminate stocks from the Russell 2000 Index with share prices of less than $5. 2. Rank remaining stocks in index by price-to-sales ratio (PSR). 3. Select 200 stocks with the lowest PSR. (A low PSR may help dampen the risks associated with a pure-growth strategy). 4. Select the 25 stocks with the highest Earnings Pressure.SM In addition, a stock will be excluded and such stock will be replaced with the stock with the next highest Earnings Pressure if, based on publicly available information as of the selection date, the company is the target of an announced business acquisition which Invesco expects will close within six months of the date of deposit.

Begin with the Standard & Poor’s MidCap 400 Index. 2. Screen out all stocks with a share price under $5. 3. Take the 100 stocks with the lowest price/book ratio. 4. Select the 15 stocks with the highest Earnings Pressure.SM In addition, a stock will be excluded and such stock will be replaced with the stock with the next highest Earnings Pressure if, based on publicly available information as of the selection date, the company is the target of an announced business acquisition which Invesco expects will close within six months of the date of deposit. Nasdaq Select 10 Strategy 1. Select the 20 largest market capitalization stocks in the Nasdaq-100 Index. 2.

Bank of America Corporation Cisco Systems, Inc. Exxon Mobil Corporation General Electric Company Hewlett-Packard Company Intel Corporation Johnson & Johnson JPMorgan Chase & Company Microsoft Corporation Sector diversification and style breakout Earnings Pressure is a proprietary formula which uses the increase in estimates of future earnings by analysts that follow each stock. The portfolio consultant calculates Earnings Pressure as follows: (1) Obtain the Consensus EPS for the next 12-month period for each stock included in the Index from which the stocks are chosen as of the selection date of the Portfolio. (2) Obtain the Consensus EPS for the end of each of the most recent three months prior to the selection date of the portfolio and combine them to obtain the average Consensus EPS over the most recent three months (fixed multipliers are used to increase the weighting of the more recent Consensus EPS figures). (3) Calculate the relative changes in Consensus EPS over the most recent three months by subtracting the amount obtained in (2) above from the amount obtained in (1) above (the Change in Consensus EPS) and the dividing the Change in Consensus EPS). (4) The resulting Relative Change in Consensus EPS as calculated in (3) above is then divided by the standard deviation amount from the Zacks database which measures the variation among the individual analyst EPS data. (5) The resulting amount as calculated in (4) above is then multiplied by the number 1 plus the net number of total upward revisions minus total downward revisions in individual analyst EPS data during the most recent three month period. This is Earnings Pressure. 5 In connection with the Strategic Small-Cap Strategy, if one or more stocks are selected by both the growthcomponent and the value-component criteria, it will be counted as one selection only. As a result, to get to a total of 50 stocks, additional stocks will be identified and selected by alternately applying the growth component to arrive at another stock and then applying the value component to arrive at another stock, continuing as necessary to get to 50 stocks. Approximately equal dollar amounts are invested in each stock. 6 The strategy does not include stocks from Singapore, which in the opinion of Invesco may be subject to undue market volatility and political instability over time. Any stocks which are passive foreign investments companies are also eliminated from the strategy. In general the classifications used were based first on market capitalization using the definition: Small-Cap-less than $1 billion; Mid-Cap-$1 billion to $5 billion, Large-Cap-over $5 billion. Invesco uses Price/Book to determine the growth and value characteristics. Stocks with high relative price-to-book ratios are considered growth, while stocks with low relative price-to-book ratios are considered value stocks. 4 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(s), investors should ask their advisers for a prospectus or download one at invesco.com/unittrust. Risk considerations There 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. You should consider this trust as part of a long-term investment strategy and you should consider your ability to pursue it by investing in successive trusts, if available. You will encounter tax consequences associated with reinvesting from one trust to another. Investing in foreign securities involves certain risks not typically associated with investing solely in the United States. This may magnify volatility due to changes in foreign exchange rates, the political and economic uncertainties in foreign countries, and the potential lack of liquidity, government supervision and regulation. This trust is concentrated in the information technology industry. There are certain risks specific to technology stocks such as volatile stock prices, rapid product obsolescence, and speculative trading. Stocks of small companies are often more volatile than those of larger companies as a result of several factors such as limited trading volumes, products or financial resources, management inexperience and less publicly available information. The Russell 2000 Index is an unmanaged index generally representative of the U.S. market for small-capitalization stocks. The Morgan Stanley Capital International Europe, Australasia, and Far East Index (“MSCI EAFE”) is an unmanaged index generally representative of major overseas stock markets. NASDAQ 100 index represents 100 of the largest non-financial, domestic and international companies traded on the NASAQ Stock Market, Inc. based on market capitalization. The Standard & Poor’s MidCap 400, introduced in 1991, is now the most widely used index for mid-sized companies. S&P MidCap 400 covers approximately 7% of the U.S. equities market.

The Morningstar Equity Style Box™ is based on holdings as of the date of deposit of the trust and may vary thereafter. The Morningstar Equity Style Box™ placement is based on two variables.

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. www.invesco.com/unittrust Invesco 11 Greenway Plaza, Suite 2500 Houston, TX 77046-1188 www.invesco.com Invesco Distributors, Inc. U-ENDX104-FCT-1 10.10
