Performance data quoted represents past performance and is no guarantee of future results. Current performance may be lower or higher than the performance data quoted. Investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than the original cost. Returns less than one year are not annualized. Net asset value (NAV) prices are used to calculate market price performance prior to the date when the fund first traded on an exchange. Market performance is determined using the bid/ask midpoint at 4:00 p.m. Eastern time, when the NAV is typically calculated. Market performance does not represent the returns you would receive if you traded shares at other times. Index performance does not represent the fund's performance. It is not possible to invest directly in an index.

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 the 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 it provides less information to traders.

  • These additional risks may be even greater in bad or uncertain market conditions.

  • The ETF will publish on their website each day a "Proxy Portfolio" designed to help trading in shares of the ETF. While the Proxy Portfolio includes some of the ETF's holdings, it is not the ETF's actual portfolio.

The differences between these ETFs and other ETFs may also have advantages. By keeping certain information about the ETFs secret, these ETF 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 strategy, however, this may hurt the ETFs' performance.

For additional information regarding the unique attributes and risks of these ETFs, see the additional risk discussion at the end of this material.

The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The Morningstar Rating does not include any adjustment for sales loads. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10- year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.

Investment return and principal value of security investments will fluctuate. The value at the time of redemption may be more or less than the original cost. Past performance is no guarantee of future results.

The fund is an actively managed ETF that does not seek to replicate the performance of a specified index.

Proxy Portfolio Risk: The goal of the Proxy Portfolio is to track closely the daily performance of the Actual Portfolio. The Proxy Portfolio is designed to reflect the economic exposures and the risk characteristics of the Actual Portfolio on any given trading day.

  • ETFs trading on the basis of a published Proxy Portfolio may exhibit wider premiums and discounts, bid/ask spreads, and tracking error than other ETFs using the same investment strategies that publish their portfolios on a daily basis, especially during periods of market disruption or volatility. Therefore, shares of the fund may cost investors more to trade than shares of a traditional ETF.

  • Each day the fund calculates the overlap between the holdings of the prior Business Day's Proxy Portfolio compared to the Actual Portfolio (Proxy Overlap) and the difference, in percentage terms, between the Proxy Portfolio per share NAV and that of the Actual Portfolio (Tracking Error).

  • Although the fund seeks to benefit from keeping its portfolio information secret, market participants may attempt to use the Proxy Portfolio 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.

Premium/Discount Risk: Although the Proxy Portfolio 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 net asset value (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.

Trading Issues Risk: Trading halts may have a greater impact on this fund compared to other ETFs due to the fund's nontransparent structure.

Authorized Participant Concentration Risk: Only an authorized participant may engage in creation or redemption transactions directly with the fund. The fund may have a limited number of institutions that act as authorized participants. The fact that the fund is offering a novel and unique structure may affect the number of entities willing to act as Authorized Participants. During times of market stress, Authorized Participants may be more likely to step away from this type of ETF than a traditional ETF.
