Invesco PowerShares Announces Zero Capital Gains Distributions for 2008 on 119 of 120 Funds

CHICAGO, IL--(Marketwire - December 4, 2008) - Invesco PowerShares Capital Management LLC, a leading provider of exchange-traded funds (ETFs), today announced that it expects to pay zero capital gains distributions for 119 of its 120 equity and fixed-income exchange-traded funds for 2008.

To date, Invesco PowerShares has never made a capital gain distribution to shareholders of its equity or fixed-income based ETF portfolios. Only one PowerShares ETF -- PowerShares S&P 500 BuyWrite Portfolio (NYSE: PBP), which was named "Most Innovative New ETF" in 2007 -- is estimated to realize a small capital gains distribution (see table below), due largely in part to the unique underlying index methodology which writes covered calls on the S&P 500 Index.

"We are very pleased to announce zero capital gains payouts for the year on all but one of our ETFs," said Bruce Bond, President and CEO of Invesco PowerShares. "At a time when the financial markets and many funds have lost significant value over the past year, the last thing investors want is to be hit with a tax bill. Taxes may be the most critical and overlooked factor in wealth creation over time, and the ETF continues to prove its viability as a tax-efficient and transparent investment vehicle."

According to a recent Lipper study, in 2007 mutual funds paid out nearly $393 billion, or 3% of their market share in capital gains to their shareholders.(1) That number is expected to increase in 2008 as redemptions have forced many fund managers to liquidate positions, inherently creating capital gains. By comparison, PowerShares equity and fixed-income ETFs had no capital gains distributions in 2007.

The only PowerShares equity ETF expected to pay a capital gain distribution for 2008 -- PBP -- is unique in the fact that it accounts for its gain or loss on its investments for federal income tax purposes on a daily mark-to-market basis. Year-to-date (as of 12/01/08), the PowerShares S&P 500 BuyWrite Portfolio had outperformed the S&P 500 Index by over 9%. "We believe that the recent success of PBP is a testament to the effectiveness of the underlying index methodology," Bond said. "The premiums shareholders have collected on the covered call options over the past year show that the Fund is doing exactly what it has been designed to do."

Past performance is not a guarantee of future results: current performance may be higher or lower than performance quoted. Investment returns and principal value will fluctuate and Shares, when redeemed, may be worth more or less than their original cost. The Shares' performance reflects fee waivers, absent which performance would have been lower. See invescopowershares.com for the most recent month-end performance numbers. The S&P 500 Index is an unmanaged index considered representative of the U.S. stock market.

Generally, the mark-to-market gains or losses from the stock portfolio positions will be compared with the mark-to-market gains or losses from the call options positions on a daily basis. What this means to investors is to the extent there is more gain from the call options than from the stock positions, such gain will generally be taxed as 60% long-term capital gain and 40% short-term capital gain, which is the case this year.

There are risks involved with investing in ETFs including possible loss of money. Shares are not actively managed and are subject to risk similar to stocks and covered call options, as well as those risks related to short selling and margin maintenance.

Covered call options strategies are not suitable for all investors.

Shares are not FDIC insured, may lose value and have no bank guarantee.

There are additional risks involved in writing (selling) covered call options on the stocks of the S&P 500 Index (Index). The Fund, by writing covered call options on this Index, will give up the opportunity to benefit from potential increases in the value of the index stocks above the exercise prices of the options, but will continue to bear the risk of declines in the value of the Index. The premiums received from the options may not be sufficient to offset any losses sustained from the volatility of the Index over time. In addition, exchanges may suspend trading of options in volatile markets. If trading is suspended, the Fund may be unable to write (sell) options at times that may be desirable or advantageous for the Fund to do so. Trading suspensions may limit the Fund's ability to achieve its investment objectives.

The Fund may be required to sell investments from its portfolio to make cash settlement on (or transfer ownership of an Index stock to physically settle) any options that are exercised. Such sales (or transfers) may occur at inopportune times, and the Fund may incur transaction costs that increase its expenses.
