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. Before investing, investors should carefully read the prospectus and consider the investment objectives, risks, charges and exp enses. For this and more complete information about the trust, 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 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 consumer discretionary and consumer staples sector. Companies that manufacture, distribute and provide consumer products and services face risks such as intense competition, the lack of serious barriers to entry for on-line entrants, economic recession and a slowdown in consumer spending trends. A portfolio concentrated in a single market sector may present more risk than a portfolio broadly diversified over several sectors. 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.
