Invesco PowerShares MENA Frontier Countries ETF Lists on NASDAQ

Invesco PowerShares, a leading provider of exchange-traded funds (ETFs), announced that its frontier countries portfolio, designed to provide access to certain equity markets in the Middle East and North Africa, begins trading today on the NASDAQ Stock Market®.

The ticker symbol and ETF portfolio name follows:

--  PMNA - PowerShares MENA Frontier Counties Portfolio
    

"The PowerShares MENA Frontier Countries Portfolio replicates an index that takes into account certain foreign ownership limitations encountered when investing in certain countries in the Middle East and North Africa," said Bruce Bond, president and CEO of Invesco PowerShares. "We believe PMNA represents a compelling new vehicle for investors to access frontier equity markets of the MENA region."

The PowerShares MENA Frontier Countries Portfolio (PMNA) is based on the NASDAQ OMX Middle East North Africa Index(SM). This Index is designed to measure the performance of the largest and most liquid securities of companies domiciled in Middle Eastern and North African countries included in the Index that have smaller economies or less developed capital markets than traditional emerging markets. The Index currently includes securities domiciled in: Egypt, Morocco, Oman, Lebanon, Jordan, Kuwait, Bahrain, Qatar and United Arab Emirates (Index currently includes the emirates of Dubai and Abu Dhabi).

Many of these frontier countries impose restrictions on foreign investments, including foreign ownership limitations. These restrictions may vary from issuer to issuer. At each quarterly rebalance and reconstitution, NASDAQ OMX Group, Inc., the index provider, takes into account the current foreign ownership limitations and locked-in stock. In addition, when a security in the Index reaches its limitations on foreign ownership, it will be removed from the Underlying Index.

An investment in securities of frontier market countries involves risks not associated with investments in securities of developed countries.
