These ETFs are diff­erent from traditional ETFs. Traditional ETFs tell the public what assets they hold each day. These ETFs will not. This may create additional risks for your investment. For example:

• You may have to pay more money to trade the ETFs’ shares. These ETFs will provide less information to traders, who tend to charge more for trades when they have less information.
• The price you pay to buy ETF shares on an exchange may not match the value of an ETF’s portfolio. The same is true when you sell shares. These price di­fferences may be greater for these ETFs compared to other ETFs because they provide less information to traders.
• These additional risks may be even greater in difficult or uncertain market conditions.
• The di­fferences between these ETFs and other ETFs may also have advantages. By keeping certain information about the ETFs undisclosed, these ETFs may face less risk that other traders can predict or copy its investment strategy. This may improve the ETFs’ performance. If other traders are able to copy or predict the ETFs’ investment strategies, however, this may hurt the ETFs’ performance. For additional information regarding the unique attributes and risks of these ETFs, see the ActiveShares prospectus/registration statement.
• The methodology for calculating the VIIV is available on this website.

The Verified Intraday Indicative Value. Information regarding the intraday value of shares of the Funds, also known as the VIIV, is calculated and disseminated every second throughout each trading day by the Listing Exchange or by market data vendors or other information providers. It is available on websites that publish updated market quotations during the trading day, like Yahoo Finance (https:// finance.yahoo.com), by searching for a Fund’s ticker plus the extension .IV, though some websites require their own unique extensions.

• The VIIV is intended to provide investors and other market participants with a highly correlated per share value of the underlying portfolio that can be compared to the current market price.
• Although the VIIV is intended to provide investors with enough information to allow for an effective arbitrage mechanism that will keep the market price of the Fund at or close to the underlying NAV per Share of the Fund, there is a risk (which may increase during periods of market disruption or volatility) that market prices will vary significantly from the underlying NAV of the Fund;
• ETFs trading on the basis of a published VIIV may trade at a wider bid/ask spread than ETFs that publish their portfolios on a daily basis, especially during periods of market disruption or volatility, and therefore, may cost investors more to trade; and
• Although the Fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the VIIV to identify a Fund’s trading strategy, which if successful, could result in such market participants engaging in certain predatory trading practices that may have the potential to harm the Fund and its shareholders.

Because the Fund’s shares are traded in the secondary market, a broker may charge a commission to execute a transaction in shares, and an investor also may incur the cost of the spread between the price at which a dealer will buy shares and the somewhat higher price at which a dealer will sell shares.

Government aerospace regulation and spending policies can significantly affect the aerospace industry because many companies involved in the aerospace industry rely to a large extent on U.S. (and other) Government demand for their products and services.
