THE STAFF NOTES THAT THE STATED GOAL WITH THE PORTFOLIO IS TO "CHOOSE WELL-CAPITALIZED COMPANIES WITH STRONG MARKET POSITIONS."

Additional disclosure has also been added to the section entitled "Portfolio Selection Process" describing how the securities are selected for the Trust. Risk Factors ____________ 3. THE STAFF NOTES THAT THE RISK DISCLOSURE INCLUDES A STATEMENT REGARDING THE COVID-19 IMPACT AND ASKS THE TRUST TO PLEASE CONSIDER WHETHER THE TRUST'S RISK DISCLOSURES, INCLUDING CURRENT ECONOMIC CONDITIONS, SHOULD BE UPDATED IN LIGHT CURRENT MARKET EVENTS AND CONDITIONS RESULTING FROM THE PANDEMIC. IF THE REGISTRANT BELIEVES THAT NO UPDATED DISCLOSURE IS WARRANTED, PLEASE EXPLAIN SUPPLEMENTALLY WHY NOT. Response: The current disclosure regarding the COVID-19 impact in the "Current Economic Conditions" risk has been replaced with the following: Local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on the Trust and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Trust's portfolio securities and could result in disruptions in the trading markets. Any such circumstances could have a materially negative impact on the value of the Trust's Units and result in increased market volatility. The recent outbreak of a respiratory disease designated as COVID-19 was first detected in China in December 2019. The global economic impact of the COVID-19 outbreak is impossible to predict but is expected to disrupt manufacturing, supply chains and sales in affected areas and negatively impact global economic growth prospects. The COVID-19 outbreak has also caused significant volatility and declines in global financial markets, which have caused losses for investors. The impact of the COVID-19 outbreak may be short term or may last for an extended period of time, and in either case could result in a substantial economic downturn or recession. 4. PLEASE INCLUDE A RISK FACTOR FOR LARGE CAPITALIZATION COMPANIES OR EXPLAIN SUPPLEMENTALLY WHY IT IS NOT RELEVANT. Response: "Large Capitalization Companies" risk has been added to the prospectus. 5.
