Invesco PowerShares Announces Shift to Fundamental Index(R) Approach for High Yield Corporate Bond Portfolio (PHB)

Fund Renamed to Reflect Change to New Index


CHICAGO, IL--(Marketwire - August 2, 2010) -  Invesco PowerShares, a leading provider of exchange-traded funds (ETFs), announced that effective Aug. 2, 2010, the PowerShares High Yield Corporate Bond Portfolio (PHB) began tracking the RAFI® High Yield Bond Index and was renamed the PowerShares Fundamental High Yield® Corporate Bond Portfolio. PHB is the first fixed-income ETF to use Research Affiliates' Fundamental Index methodology.

"We are very pleased to expand our relationship with Research Affiliates and offer investors another industry first with the introduction of an innovative fixed-income index strategy that incorporates the Fundamental Index methodology," said Ben Fulton, Invesco PowerShares managing director of global ETFs. Invesco PowerShares already offers eight equity ETFs based on FTSE RAFI indexes, which also make use of the Fundamental Index methodology.

Traditional bond indices give the largest weights to the biggest debtors, potentially exposing investors to greater risks of default. In contrast, Research Affiliates' Fundamental Index methodology uses fundamental measures of company size, including book value, sales, dividends and cash flow, to set constituent weights.

"By weighting companies based on fundamental measures of their resources available to service debt, we believe the PowerShares Fundamental High Yield Corporate Bond Portfolio represents a compelling alternative to market-cap-weighted fixed-income portfolios and provides investors the potential for improved risk-adjusted returns," Mr. Fulton added. 

"Traditional bond indexes are flawed. Why would you want to give the biggest portion of assets to those companies that are the biggest debtors?" said Rob Arnott, chairman and founder of Research Affiliates, LLC, which developed the new index in conjunction with Ryan ALM, Inc. "The RAFI High Yield Bond Index offers a compelling alternative to traditional high-yield bond indexes." Ron Ryan, CEO of Ryan ALM, adds, "We believe the index rules that we designed and maintain for the RAFI Index provide the highest liquidity, creditworthiness, investability and interest rate risk balance for a high-yield index today."

PHB will normally invest at least 80% of its total assets in high-yield bonds that comprise the Index. The Index measures potential returns of a theoretical portfolio of high yield, U.S. dollar denominated corporate bonds registered for sale in the United States whose issuers are public companies listed on a major U.S. stock exchange.

The underlying index is rebalanced at the end of every month based on the index rules and weighted according to a composite RAFI weight that is calculated for each eligible company. Composite RAFI weights are calculated using the following four factors: current book value of assets as well as gross sales, gross dividends and cash flow, each based on five-year averages. The target RAFI weights are reconstituted annually.

The Fund previously tracked the WellsFargo® High Yield Bond Index. The fund continues to be offered on the NYSE Arca under the existing ticker symbol PHB.
