Risks: Investing involves risk, including the possible loss of principal. Shares of any ETF are bought and sold at market price (not NAV) and may trade at a discount or premium to NAV. Shares are not individually redeemable from the Fund and may be only be acquired or redeemed from the fund in creation units. Brokerage commissions will reduce returns.

There are no guarantees that a company will pay or continually increase its dividends. The Fund invests in small- and mid-capitalization companies which may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. Smaller-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes. ADRs (American Depository Receipts) involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Investments in REITs (real estate investment trusts) involve unique risks. REITs may be affected by changes in the value of their underlying properties or economic factors affecting the real estate industry. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities.

Holdings and allocations are subject to change at any time. Past performance does not guarantee future results. Cash flow is the net amount of cash and cash-equivalents moving into and out of a business. 30-Day Median Bid/Ask Spread is computed by: identifying the Fund’s national best bid and national best offer as of the end of each 10 second interval during each trading day of the last 30 calendar days; dividing the difference between each such bid and offer by the midpoint of the national best bid and national best offer; and identifying the median of those values, expressed as a percentage rounded to the nearest hundredth. The Russell 2500® Index measures the performance of the small to mid-cap segment of the U.S. equity universe. It includes approximately 2500 of the smallest securities based on a combination of market cap and current index membership. The Index is completely reconstituted annually to ensure larger stocks do not distort the performance and characteristics of the true small to mid-cap opportunity set. It is not possible to invest directly in an index.
