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

"We are very pleased to announce zero capital gains payouts for the year onall but one of our ETFs," said Bruce Bond, President and CEO of InvescoPowerShares. "At a time when the financial markets and many funds have lostsignificant value over the past year, the last thing investors want is tobe hit with a tax bill. Taxes may be the most critical and overlookedfactor in wealth creation over time, and the ETF continues to prove itsviability 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 theirshareholders.(1) That number is expected to increase in 2008 as redemptionshave forced many fund managers to liquidate positions, inherently creatingcapital gains. By comparison, PowerShares equity and fixed-income ETFs hadno capital gains distributions in 2007.

The only PowerShares equity ETF expected to pay a capital gain distributionfor 2008 -- PBP -- is unique in the fact that it accounts for its gain or losson 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 500BuyWrite Portfolio had outperformed the S&P 500 Index by over 9%. "Webelieve that the recent success of PBP is a testament to the effectivenessof the underlying index methodology," Bond said. "The premiums shareholdershave collected on the covered call options over the past year show that theFund is doing exactly what it has been designed to do."

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