SMid Capital Strength Portfolio, Series 15

Because smaller companies are often less reliant on the capital markets for credit, they can be more nimble and better able to adjust in periods of economic change, than large companies. Additionally, this results in generally better balance sheet integrity than large companies.

The SMid Capital Strength Portfolio invests in small and mid-size companies. These companies are more likely to be in an earlier stage of their economic life cycle than mature large-cap companies. In addition, the ability to take advantage of share price discrepancies is likely to be greater with smaller stocks than with more widely followed large-cap stocks.

Our goal with the trust is to invest in undervalued companies with strong market positions that, in our opinion, have the following qualities:

• Strong balance sheets;
• Skilled management;
• Highly liquid;
• Ability to generate earnings growth; and
• Record of financial strength and profit growth.

Portfolio Objective

This unit investment trust seeks above-average capital appreciation; however, there is no assurance the objective will be met. The portfolio terminates approximately two years from the initial date of deposit.

Portfolio Selection Process

Through our selection process we seek to find the stocks that we believe have the best prospects for above-average capital appreciation.

Identify the Universe
The first step in our selection process is to identify the universe of stocks from which we will select the portfolio. We begin by selecting the companies listed in the S&P MidCap 400 and S&P SmallCap 600 Indexes.

Screen For Financial Strength
The next step in our process is to evaluate companies based on multiple factors. These factors are designed to identify those stocks which exhibit strong fundamental characteristics and to eliminate those that do not meet our investment criteria.

Examine Historical Financial Results
The next step in our process is to look for those companies that have earned a net cash flow return on investment that is above the average of their peers. Historically, companies that have increased their cash flows at a higher rate have rewarded shareholders with superior total returns.

Select Companies with Attractive Valuations for the Portfolio
The final step in our process is to select companies based on the fundamental analysis of our team of research analysts. The stocks selected for the portfolio are those that meet our investment objectives, trade at attractive valuations, and in our opinion, are likely to exceed market expectations of future cash flows.

Risk Considerations:
An investment in this unmanaged unit investment trust should be made with an understanding of the risks involved with owning common stocks, such as an economic recession and the possible deterioration of either the financial condition of the issuers of the equity securities or the general condition of the stock market.

An investment in a portfolio containing small-cap and mid-cap companies is subject to additional risks, as the share prices of small-cap companies and certain mid-cap companies are often more volatile than those of larger companies due to several factors, including limited trading volumes, products, financial resources, management inexperience and less publicly available information.

An investment in a portfolio containing equity securities of foreign issuers is subject to additional risks, including currency fluctuations, political risks, withholding, the lack of adequate financial information, and exchange control restrictions impacting foreign issuers.

The value of the securities held by the trust may be subject to steep declines or increased volatility due to changes in performance or perception of the issuers.
