Invesco PowerShares to Introduce the First Fundamental Pure Style ETFs

CHICAGO, IL--(Marketwire - May 23, 2011) - Invesco PowerShares Capital Management LLC, a leading global provider of exchange-traded funds (ETFs), announced today plans for a suite of nine Fundamental Pure Style ETFs based on the Research Affiliates^® Fundamental Index^® (RAFI^®) methodology.

On June 16, 2011, Invesco PowerShares will list the PowerShares Fundamental Pure Large Growth Portfolio (PXLG) based on the RAFI^® Fundamental Large Growth Index, and the PowerShares Fundamental Pure Large Value Portfolio (PXLV) based on the RAFI^® Fundamental Large Value Index on the NYSE Arca.

In addition, Invesco PowerShares will be changing the indexes, names and ticker symbols for seven existing ETFs in its Intellidex style/size lineup to the RAFI Fundamental US Style Index Series (RAFI Index Series), to provide investors with a complete suite of style box ETFs based on the RAFI Fundamental Index methodology. The rebranded portfolios management fees will be reduced to 0.29% and their operating expenses (excluding certain expenses) will be capped at 0.39% until at least August 31, 2012.

The names and tickers for the full suite of nine PowerShares Fundamental Pure Style ETFs are listed in the table below.

"We continuously review and analyze ways to improve our overall product lineup," said Ben Fulton, Invesco PowerShares managing director of global ETFs. "We believe the change to the RAFI Index Series and lower fees will provide investors with the potential for improved risk-adjusted returns, and will position our innovative family of ETFs for the future."

"We currently offer six equity ETFs based on the RAFI Fundamental Index methodology. The funds have all outperformed their benchmarks since their respective inception dates¹," said John Feyerer, head of product strategy & research at Invesco PowerShares. "PowerShares Fundamental Pure Portfolios incorporate the RAFI Fundamental Index investment criteria of cash flow, book value, sales and dividends to determine a stock's weight. We believe this methodology has shown the potential to produce improved risk-adjusted returns compared to cap-weighted benchmarks."

Details for the seven rebranded PowerShares ETFs including portfolio names, tickers and indexes are listed below.

The RAFI Index Series is constructed from the 2,500 largest U.S. listed companies, based on the following four fundamental measures of firm size: latest available book value, cash flow averaged over the prior five years, sales averaged over the prior five years and total dividend distributions averaged over the prior five years. A composite fundamental weight is calculated for each firm by equally weighting the four fundamental measures. For companies that have never paid dividends, that measure will be excluded from the average. Each company is then classified as "large," "mid" or "small" and "growth," "core" or "value" in the following manner:

1) Stocks are segregated into three size groups: "large," "mid" and "small." Companies are divided amongst these groups based on their fundamental weight. Securities which have a substantially different fundamental weight relative to their market cap weight are excluded.

2) Once classified into the three size groups, RAFI uses a methodology using fundamental measures of growth and value to give each company a style score. Based on this style score companies are classified as "growth," "core" or "value."

3) Stocks within each sub-index are weighted by their composite fundamental weight.

Each index in the RAFI Index Series is reconstituted and rebalanced annually on the third Friday of March.
