Invesco PowerShares Announces Changes to ETF Family

CHICAGO – December 19, 2012 – Invesco PowerShares Capital Management LLC, a leading global provider of exchange-traded funds (ETFs) with more than $74 billion in franchise assets, announced changes to its product line.

As part of its ongoing commitment to putting investors’ interests first, Invesco PowerShares announced that it plans to close 13 ETFs. The affected funds represent less than 1% of Invesco PowerShares’ total assets.

“We regularly review our ETF portfolios, evaluating numerous factors such as investment results, length of time in the market and investor interest," said Ben Fulton, Invesco PowerShares managing director of global ETFs. “Based on this assessment, we believe the time is right to make these moves and refocus our resources to better meet investors’ needs. As one of the leading innovators in the ETF industry, Invesco PowerShares remains fully committed to maintaining and developing a comprehensive and compelling product line of ETFs to help investors meet their financial goals.”

At a Dec. 18, 2012 meeting, the PowerShares Funds Board of Trustees approved the closings. The final day of trading on The NASDAQ Stock Market LLC (“NASDAQ”) and NYSE Arca, Inc. (“NYSE Arca”) will be Feb. 26, 2013.

Shareholders may sell their holdings on or before Feb. 26, 2013, and may incur typical transaction fees from their broker-dealer. Shareholders who do not sell their holdings on or before Feb. 26, 2013, will receive cash equal to the amount of the net asset value of their shares, which will include any capital gains and dividends, in the cash portion of their brokerage accounts on the liquidation date (currently scheduled for March 7, 2013). Shareholders will generally recognize a capital gain or loss equal to the amount received for their shares over their adjusted basis in such shares.
