-- PTRP - PowerShares Global Progressive Transportation Portfolio

"Improving the efficiency of moving people and goods worldwide through reduced fuel consumption and shortened transit times are just a few of the important issues progressive transportation companies are working to address," said Bruce Bond, president and CEO of Invesco PowerShares. "We believe the PowerShares Progressive Transportation ETF seeks to provide investors a convenient way to invest in a global portfolio of companies focused on sustainable transportation through the benefit-rich ETF structure."

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(SM). 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.
