XLES Powershares S&P Smallcap Energy Portfolio (MM)

Invesco PowerShares Capital Management LLC, a leading global provider of exchange-traded funds (ETFs), today announced the anticipated listing of two new ETFs that will provide investors with access to high-beta strategies covering emerging and international developed markets. The ETFs are expected to begin trading February 24, 2012 on the NYSE Arca. The two new portfolio names and ticker symbols are as follows:

High Beta Strategies:

• EEHB PowerShares S&P Emerging Markets High Beta Portfolio
• IDHB PowerShares S&P International Developed High Beta Portfolio

On May 5, 2011, Invesco PowerShares launched the first exchange-traded funds covering high beta and low volatility strategies for the U.S market. Today, with over $1.3 billion in AUM, the suite of PowerShares Global Factor-Driven ETFs provide advisors and investors with a disciplined approach and full range of tools for increasing beta or lowering volatility in their portfolios.

High Beta and Low Volatility Strategies (listed May 5, 2011):

• SPHB PowerShares S&P 500® High Beta Portfolio
• SPLV PowerShares S&P 500® Low Volatility Portfolio

Global Low Volatility Strategies (listed January 13, 2012):

• EELV PowerShares S&P Emerging Markets Low Volatility Portfolio
• IDLV PowerShares S&P International Developed Low Volatility Portfolio

"PowerShares Global Factor-Driven ETFs represent a new way for investors seeking to manage equity exposure by using specific factor weighted ETFs as building blocks," said Ben Fulton, Invesco PowerShares managing director of global ETFs. "Investors are seeking a more tactical approach to investing and we believe the PowerShares Global Factor-Driven ETFs can provide an efficient means to capitalize on bull markets by adding beta to their portfolio, while having the flexibility to reduce risk in flat or bear markets by adding low volatility strategies to their portfolio."

The PowerShares S&P Emerging Markets High Beta Portfolio (EEHB) is based on the S&P BMI Emerging Markets High Beta Index ("the Index"). The Fund will invest at least 90% of its total assets in the securities of companies that comprise the Index. The Index is compiled, maintained and calculated by Standard & Poor's and consists of the 200 stocks in the S&P Emerging BMI Plus LargeMid Cap Index that are the most sensitive to changes in market returns (or beta) over the past 12 months. Constituents are weighted by their corresponding beta, with the most sensitive stocks receiving the highest weights.

The PowerShares S&P International Developed High Beta Portfolio (IDHB) is based on the S&P BMI International Developed High Beta Index ("the Index"). The Fund will invest at least 90% of its total assets in the securities of companies that comprise the Index. The Index is compiled, maintained and calculated by Standard & Poor's and consists of the 200 stocks in the S&P Developed ex. US and South Korea LargeMid Cap BMI Index that are the most sensitive to changes in market returns (or beta) over the past 12 months. Constituents are weighted by their corresponding beta, with the most sensitive stocks receiving the highest weights. Although the funds seek to add beta, there is no assurance that the funds will meet that goal.

There are risks involved with investing in ETFs, including possible loss of money. Shares are not actively managed and are subject to risks including those regarding short selling and margin maintenance requirements. Ordinary brokerage commissions may apply.

Not FDIC Insured | May Lose Value | No Bank Guarantee

Shares are not individually redeemable and owners of the shares may acquire those shares from the Fund and tender those shares for redemption to the Fund in Creation Units only, typically consisting of aggregations of 50,000 shares.

Invesco Distributors, Inc. is the distributor of the PowerShares Exchange-Traded Fund Trusts.

Investing in securities of medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of more established companies.

The prices of equity securities change in response to many factors, including the historical and prospective earnings of the issuer, the value of its assets, general economic conditions, interest rates, investor perceptions and market liquidity.

Foreign securities have additional risks, including exchange-rate changes, decreased market liquidity, political instability and taxation by foreign governments.

Investment in securities in emerging market countries involves risks not associated with investments in securities in developed countries.

The Fund's use of a representative sampling approach will result in holding a smaller number of securities than are in the Underlying Index.

The Funds are non-diversified and can invest a greater portion of their 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. This may increase the Funds' volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Funds' performance.
