Emerging Markets Strength Portfolio, Series 51
What are Emerging Markets?
Emerging markets are countries that are attempting to change and improve their current
economies. Size itself is not a factor for determining an emerging market, as evidenced by China.
The objective of an emerging market is to raise economic performance and, as a result, become
a more advanced nation. Collectively, developing economies are anticipated to grow faster than
the economies of countries which are already developed.
By investing a portion of your portfolio outside the U.S., you may significantly expand your investment
choices and participate in the long-term growth potential of foreign companies. To predict which
countries will emerge and reward those for taking on the risk to invest in them is a difficult task. Through
our selection process we seek to find the emerging markets stocks that we believe have the best
prospects for above-average capital appreciation.
Portfolio Objective
This unit investment trust seeks above-average capital appreciation; however, there is
no assurance the objective will be met.
Portfolio Selection Process
Identify the Universe
We begin by selecting stocks that are based in an emerging
market or have significant business operations in emerging markets, trade on a U.S. stock exchange either
directly or through an American Depositary Receipt, and have adequate liquidity for investment.
Screen for Financial Strength
We then 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
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.
A significant percentage of securities held by the portfolio are issued by companies in the Asia Pacific region,
making the portfolio more susceptible to the economic, market, regulatory, political, natural disasters and
local risks of the Asia Pacific region. The region has historically been highly dependent on global trade which
creates a risk with this dependency on global growth. The stock markets tend to have a larger prevalence of
smaller companies that are inherently more volatile and less liquid than larger companies.
A significant percentage of securities held by the portfolio are issued by companies in Hong Kong and China.
Hong Kong and China’s emerging market economies may be subject to over-extension of credit, currency
devaluations and restrictions, decreased exports, economic recession, a reversal of economic liberalization,
political unrest or changes in Hong Kong and China’s trading status. A deterioration of the relationship
between Hong Kong or China and the United States could have negative implications on issuers from Hong
Kong and China.
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. Risks associated with investing in foreign securities
may be more pronounced in emerging markets where the securities markets are substantially smaller, less
liquid, less regulated and more volatile than the U.S. and developed foreign markets.
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.
Large capitalization companies may grow at a slower rate than the overall market.
As the use of Internet technology has become more prevalent in the course of business, the trust has become more susceptible to potential operational risks through breaches in cybersecurity.
The COVID-19 global pandemic has resulted in major disruptions to economies and markets around the world. Financial markets have experienced extreme volatility and severe losses, negatively impacting global economic
growth prospects. The duration of the COVID-19 outbreak and its effects cannot be determined with certainty and may exacerbate other political, social and economic risks.
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.
This UIT is a buy and hold strategy and investors should consider their ability to hold
the trust until maturity. There may be tax consequences unless units are purchased in
an IRA or other qualified plan.
