First Trust U.S. Treasury Securities Portfolio, Short-Term, Series 14
Ticker Symbol: FTEMUX

¹Weighted average maturity represents the average amount of time remaining until the securities held in the trust mature, taking into account each security’s weight within the portfolio based on its market value.

²Estimated current return is calculated by dividing estimated net annual interest income per unit by the public offering price.

³Estimated net yield to maturity is calculated using a formula which (1) factors in the relative weightings of the market values, yields and estimated retirements of the securities; and (2) takes into account a compounding factor, the sales charge and expenses. There is no assurance that the returns will be realized in the future because the various components used to calculate these figures will change. In addition, neither rate reflects the true return you will receive, which will be lower, because neither includes reduction in interest payments as securities mature and the effect of certain delays in distributions with respect to when the securities pay interest and when distributions are paid by the trust.

The deferred sales charge will be deducted in three monthly installments commencing 5/20/24. When the public offering price is less than or equal to $10.00 per unit, there will be no initial sales charge. If the price exceeds $10.00 per unit, you will pay an initial sales charge. The maximum sales charge for investors in fee accounts consists of the C&D fee. Investors in fee accounts are not assessed any transactional sales charges. Standard accounts sales charges apply to units purchased as an ineligible asset. The C&D fee is a charge of $0.050 per unit collected at the end of the initial offering period. If the price you pay exceeds $10.00 per unit, the C&D fee will be less than 0.50%; if the price you pay is less than $10.00 per unit, the C&D fee will exceed 0.50%. In addition to the sales charges listed, UITs are subject to annual operating expenses and organization costs.

Risk Considerations
An investment in this unmanaged unit investment trust should be made with an understanding of the risks involved with an investment in U.S. Treasury obligations which are subject to numerous risks including higher interest rates, economic recession and deterioration of the bond market or investors’ perceptions thereof.

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.
