PGF - PowerShares Financial Preferred Portfolio

† Credit ratings are assigned by Nationally Recognized Statistical Rating Organizations based on assessment of the credit worthiness of the underlying bond issuers. The ratings range from AAA (highest) to D (lowest) and are subject to change. Not rated indicates the debtor was not rated, and should not be interpreted as indicating low quality. Futures and other derivatives are not eligible for assigned credit ratings by any NRSRO and are excluded from quality allocations. For more information on rating methodologies, please visit the following NRSRO websites: standardandpoors.com and select "Understanding Ratings" under Rating Resources and moodys.com and select "Rating Methodologies" under Research and Ratings.

There are risks involved with investing in ETFs, including possible loss of money. Shares are not actively managed and are subject to risks similar to those of stocks, including those regarding short selling and margin maintenance requirements. Ordinary brokerage commissions apply. The Fund’s return may not match the return of the Underlying Index.

The Fund is considered non-diversified and may be subject to greater risks than a diversified fund.

The Fund's use of a representative sampling approach will result in its holding a smaller number of bonds than are in the underlying Index, and may be subject to greater volatility.

Investments focused in a particular industry or sector, such as the financial sector are subject to greater risk, and are more greatly impacted by market volatility, than more diversified investments.

Certain of the companies that comprise the Underlying Index, while traded on U.S. exchanges, may be issued by foreign financial institutions. Therefore, the Fund may be subject to the risks of investing in securities issued by foreign companies.

High-yield securities have additional risks, including interest-rate changes, decreased market liquidity and a larger amount of outstanding debt than investment grade securities.

Preferred securities may be less liquid than many other securities, and in certain circumstances, an issuer of preferred securities may redeem the securities prior to a specified date.

Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If a Fund is unable to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Funds if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly.

Investing in securities of small and medium-sized companies may involve greater risk than is customarily associated with investing in large companies.

Variable and floating-rate securities may be subject to liquidity risk, meaning that there may be limitations on the Fund's ability to sell the securities at any given time. Due to their variable or floating-rate features, these securities generally will pay higher levels of income in a rising interest rate environment; however, there can be no guarantee that a dividend paid by a floating-rate security will increase as interest rates rise.
