Investing involves risk, including the possible loss of principal. Shares of any ETF are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns. Narrowly focused investments typically exhibit higher volatility. The mining industry is highly volatile due to significant fluctuation in the prices of commodities, as well as political and regulatory developments. Investments in foreign securities involve political, economic and currency risks, greater volatility and differences in accounting methods. These risks are greater for investments in emerging markets. The Funds are non-diversified, meaning they may concentrate their assets in fewer individual holdings than a diversified fund. Therefore, the Funds are more exposed to individual issuer volatility than a diversified fund. Funds that are less diversified across countries or geographic regions are generally riskier than more geographically diversified funds and risks associated with such countries or geographic regions may negatively affect a Fund. Investments in small- and medium-capitalization companies tend to have limited liquidity and greater price volatility than large-capitalization companies. The PureFunds ISE Diamond/Gemstone ETF is subject to risks associated with demand and supply of gemstones in the form of jewelry/investments as well as industrial uses. Changes in consumer taste, consumer confidence, man-made alternatives, and spending among this segment of the population may have an adverse impact on the sale of gemstones in the market. The PureFunds ISE Mining Service ETF is subject to risks associated with adverse market conditions, increased competition, environmental concerns, fluctuations in commodity prices and supply and demand of hard commodities, decreased metals demand and the success of exploration projects. Legal or regulatory changes, as well as changes in government policies towards metals, could also adversely impact the mining services sector and therefore Fund performance. The PureFunds ISE Junior Silver ETF is subject to risks associated with the worldwide price of silver and the costs of extraction and production. Worldwide silver prices may fluctuate substantially over short periods of time, so the Fund's share price may be more volatile than other types of economic conditions, tax treatment, government regulation and intervention, and world events in the regions in which the companies operate. The price of equity securities of silver mining companies and silver may not always be closely correlated.

The Funds' return may not match or achieve a high degree of correlation with the return of the Underlying Index. To the extent a Fund utilizes a sampling approach, it may experience tracking error to a greater extent than if a Fund had sought to replicate the Index.

The Fund invests in some economies that are heavily dependent upon trading with key partners. Any reduction in this trading may cause an adverse impact on the economy in which the Fund invests.

Funds that are less diversified across countries or geographic regions, such as Africa, Latin America, and Australia, are generally riskier than more geographically diversified funds and risks associated with such countries or geographic regions may negatively affect a Fund. Foreign countries can privatize entities and industries. Privatized entities may lose money or be re-nationalized. Any reduction in trading with key partners may cause an adverse impact on the economy in which the Fund invests.
