Frequency Distribution of Premiums and Discounts

The performance data quoted above represents past performance. Past performance is not a guarantee of future results. Investment return and value of the Fund shares will fluctuate so that an investor's shares, when sold, may be worth more or less than their original cost. Performance may be lower or higher than performance data quoted. Recent quarter end performance data.

The above frequency distribution chart presents information about the difference between the daily market price for shares of the Fund and the Fund's reported net asset value. The amount that the fund's market price is above the reported NAV is called the premium. The amount that the fund's market price is below the reported NAV is called the discount. The market price is determined using the midpoint between the highest bid and the lowest offer on the listing exchange, as of the time that the Fund's NAV is calculated (usually 4:00 pm Eastern time). The horizontal axis of the chart shows the premium or discount expressed in basis points. The vertical axis indicates the number of trading days in the period covered by the chart. Each bar in the chart shows the number of trading days in which the Fund traded within the premium/discount range indicated.

*A unit that is equal to 1/100th of 1% and is used to denote the change in a financial instrument.

1 Market Price is based on the midpoint of the bid/ask spread at 4 p.m. ET and does not represent the returns an investor would receive if shares were traded at other times.

2 The Premium / Discount is the amount (stated in dollars or percent) by which the selling or purchase price of an ETF is greater than (premium) or less than (discount) its face amount/value or net asset value (NAV).

3"Other Expenses" are based on estimated amounts for the current fiscal year and calculated as a percentage of the Fund's net assets. Since the Fund has a limited operating history, a tax expense of 0.00% has been assumed since it cannot be predicted whether the Fund will incur a benefit or liability in the future.
