-- PTRP - PowerShares Global Progressive Transportation Portfolio

"Global trade, urbanization and rising energy costs have created a growing need for more efficient and sustainable ways to transport goods and services," said Bruce Bond, president and CEO of Invesco PowerShares. "We believe the PowerShares Global Progressive Transportation Portfolio (PTRP) will provide investors a precise way to access the companies that focus on this important sector with the inherent structural benefits of an ETF."

The World Business Council for Sustainable Development defines sustainable transportation as the ability to meet the needs of society to move freely, gain access, communicate, trade and establish relationships without sacrificing other essential human or ecological values today or in the future.

The PowerShares Global Progressive Transportation Portfolio (PTRP) is based on the Wilder NASDAQ OMX® Global Energy Efficient Transport Index. The index tracks the performance of a global group of companies focused on technologies for utilization of greener, more efficient sources of energy to initiate a societal transition toward cleaner, less costly and more efficient means of transportation. The Index includes companies listed on global stock exchanges involved in four core focus areas: alternative vehicles; rail and subway systems; sea, land, air and intermodal; and transport innovation. The Index is rebalanced quarterly using a modified market capitalization-weighting methodology with consideration to trading volume and float-adjusted market capitalization minimums.

There are risks involved with investing in ETFs including possible loss of money. Shares are not actively managed and are subject to risk similar to stocks and covered call options, as well as those risks related to short selling and margin maintenance. Ordinary brokerage commissions apply.

Shares are not FDIC insured, may lose value and have no bank guarantee.

Small- and Medium-Sized Company Risk Information

An investment in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in more established, larger sized companies.

Foreign Risk Information

An investment in the securities of non-U.S. issuers involves risks beyond those associated with investments in U.S. securities, including, but not limited to: greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity, political instability, negative impact of changes in currency exchange rates or foreign governmental regulation, currency risk, fluctuation due to changes in interest rates, effects of monetary policies issued by the United States, foreign governments, central banks or supranational entities and currency controls or other national or global political economic developments, among others.

Non-Diversified Fund Risk Information

The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.
