Fixed income is an area of ongoing attention for PowerShares, Bond says, and the firm plans to expand its capabilities here in Q4 and into 2008.

The 1-30 Laddered Treasury Portfolio will generally consist of 30 Treasury issues with maturities approximately one year apart, and seeks to replicate the composition and match performance of this index, before fees and expenses.

Risks of Owning Exchange-Traded Funds

There are risks involved with investing in ETFs including possible loss of money. Shares are subject to risks similar to those of investing in any fund of emerging market sovereign debt securities, municipal fixed income securities and treasury bond securities, including credit, interest rate and general market risks, as well as those risks related to short selling and margin maintenance. Generally, the prices of income securities tend to fall as interest rates rise. The Shares are subject to market fluctuations caused by such factors as economic, political, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Please see the prospectus for more complete information regarding an investment in the Funds. Shares are not FDIC insured, may lose value and have no bank guarantee.

The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole.

PowerShares Emerging Markets Sovereign Debt Portfolio

Investments in sovereign debt securities involve special risks. The governmental authority that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to: the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; or the government debtor's policy towards the International Monetary Fund and the political constraints to which a government debtor may be subject. If an issuer of sovereign debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In certain cases, remedies must be pursued in the courts of the defaulting party itself, and the Fund's ability to obtain recourse may be limited. Government obligors in emerging market countries are among the world's largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. Historically, certain issuers of the government debt securities in which the Fund may invest have experienced substantial difficulties in meeting their external debt obligations, resulting in defaults on certain obligations and the restructuring of certain indebtedness. Such restructuring arrangements have included obtaining additional credit to finance outstanding obligation and the reduction and rescheduling of payments of interest and principal through the negotiation of new or amended credit agreements. Please see the prospectus for more complete information regarding the risks of investing in emerging markets and sovereign debt.
