Invesco PowerShares to Introduce Family of Global Asset Allocation ETFs

Strategic Asset Allocation Delivered Within the Tax-Efficient ETF Structure

CHICAGO, IL -- May 1, 2008 -- Invesco PowerShares Capital Management LLC, a leading provider of exchange-traded funds (ETFs), today announced the anticipated listing of three innovative ETF portfolios designed to provide investors convenient access to long-term, core asset allocation strategies through investment in other ETFs. The new portfolios, based on three defined risk profiles targeting a given percentage of investment in equity and fixed-income securities: balanced, balanced growth and growth, are expected to begin trading May 15, 2008 on the American Stock Exchange.

The anticipated ticker symbols and ETF portfolio names are:

    PCA - PowerShares Autonomic Balanced NFA Global Asset Portfolio
    PAO - PowerShares Autonomic Balanced Growth NFA Global Asset Portfolio
    PTO - PowerShares Autonomic Growth NFA Global Asset Portfolio

PowerShares Autonomic Global Asset Portfolios are the first of a new family of PowerShares ETF portfolios that seek to provide global, risk-controlled asset allocation strategies through investment in other ETFs.

"We are truly thrilled to provide investors efficient access to world-class asset allocation strategies using the benefit-rich ETF format," said Bruce Bond, president and CEO of Invesco PowerShares. "The Autonomic NFA Global Asset Portfolios seek to deliver the benefits of risk-targeted asset allocation combined with the anticipated tax efficiency of ETFs."

Asset allocation is an investment strategy that seeks to balance risk and reward in a portfolio by spreading investments over several types of asset classes, such as equities, fixed-income and other non-equity correlated assets. Widely considered to be the basis of a properly designed long-term investment program, strategic asset allocation is employed by institutions and sophisticated investors to reduce a portfolio's exposure to a downturn in any one particular type of asset, while seeking to provide higher risk-adjusted returns over the long term.

The New Frontier Global Dynamic Indexes underlying the PowerShares Autonomic NFA Global Asset Portfolios are constructed using the patented Resampled Efficiency(TM) (RE) optimization process from New Frontier Advisors.

"With Resampled Efficiency, the PowerShares Autonomic ETFs bring state-of-the-art institutional quality asset management tools that are designed to maximize core investment management and long-term objectives to advisors and investors, including demonstrably improved portfolio optimization and rebalancing," said Dr. Richard Michaud, president and CIO of New Frontier Advisors, LLC.

Michaud noted that with attributes like transparency, tax-efficiency and access to nearly every major asset class, ETFs are an ideal asset allocation tool. "We are pleased to join with Invesco PowerShares to bring these innovative products to market," he said.
