Mega-Cap Portfolio, Series 73

The Mega-Cap Portfolio invests in some of the largest companies in the world. These companies are well-known blue chip companies that are widely regarded as leaders in their respective industries. These companies, known for their quality products and services, are some of the most successful in the world and have the potential to provide their stockholders with a greater degree of stability and consistent performance over time.

Mega-cap companies typically have a notable presence throughout the world. Recently, more opportunities have arisen outside of the United States, where populations are growing rapidly and market penetration is lower. The United Nations projected that the world population surpassed 8 billion people in November 2022 and estimates that number could reach approximately 8.5 billion by 2030.

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.

You should be aware that the portfolio is concentrated in stocks in the information technology sector which involves additional risks, including limited diversification. The companies engaged in the information technology sector are subject to fierce competition, high research and development costs, and their products and services may be subject to rapid obsolescence. Technology company stocks, especially those which are Internet-related, may experience extreme price and volume fluctuations that are often unrelated to their operating performance.

Securities of non-U.S. issuers are subject to additional risks, including currency fluctuations, political risks, withholding, the lack of adequate financial information, and exchange control restrictions impacting non-U.S. issuers.

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.

Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities could have a significant impact on certain investments as well as performance.

The ongoing effects of the COVID-19 global pandemic, or the potential impacts of any future public health crisis, may cause significant volatility and uncertainty in global financial markets. While vaccines have been developed, there is no guarantee that vaccines will be effective against future variants of the disease.

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.
