PRFF Powershares Etf Trust (MM)

Invesco PowerShares Capital Management LLC, a leading provider of exchange-traded funds (ETFs), today announced that it anticipates transferring 79 PowerShares ETFs currently listed on the American Stock Exchange (Amex) to the NYSE Arca listing and trading platform. The move of the PowerShares ETFs comes as a result of the merger of the Amex and NYSE Euronext, the holding company for NYSE Arca. On Oct. 1, 2008, the Amex and NYSE Euronext announced that their transaction had successfully closed. To accommodate one of the largest fund transfers in the history of the exchanges, Invesco PowerShares will bring these funds to NYSE Arca in two phases. It is anticipated that the last trading day on the Amex for most of these PowerShares ETFs will be Friday, Oct. 31, 2008 with Monday, Nov. 3, 2008 being the first trading day on NYSE Arca. It is then anticipated that a second group of the remaining PowerShares ETFs will leave Amex and begin trading on NYSE Arca on or about Nov. 25, 2008. Current shareholders are not required to take any actions as a result of this change.

The entire list of PowerShares ETFs moving to NYSE Arca is provided in the following table:
