CHICAGO, IL--(Marketwired - Jul 8, 2014) - Invesco PowerShares Capital Management LLC, a leading global provider of exchange-traded funds (ETFs), today announced that the Fund name, underlying index, investment objective, certain fundamental and non-fundamental investment policies and principal investment strategies changed for its three PowerShares Municipal Bond ETFs.

Effective July 8, 2014, the PowerShares Insured National Municipal Bond Portfolio (PZA) will track the BofA ML National Long-Term Core Plus Municipal Securities Index (UNAP), the PowerShares Insured New York Municipal Bond Portfolio (PZT) will track the BofA ML New York Long-Term Core Plus Municipal Securities Index (UNYP) and the PowerShares Insured California Municipal Bond Portfolio (PWZ) will track the BofA ML California Long-Term Core Plus Municipal Securities Index (UCAP).

Ticker		Former Fund Name		New Fund Name		Former Index		New Index
PZA		PowerShares Insured National Municipal Bond Portfolio		PowerShares National AMT-Free Municipal Bond Portfolio		BofA ML National Insured Long-Term Core Plus Municipal Securities Index (UPCM)		BofA ML National Long-Term Core Plus Municipal Securities Index (UNAP)
PZT		PowerShares Insured New York Municipal Bond Portfolio		PowerShares New York AMT-Free Municipal Bond Portfolio		BofA ML New York Insured Long-Term Core Plus Municipal Securities Index (UPNY)		BofA ML New York Long-Term Core Plus Municipal Securities Index (UNYP)

Since 2007, when the PowerShares Insured Municipal Bond Portfolios first listed, the US market for insured municipal bond securities has shrunk by over 40 percent¹, making the available supply of insured-municipal securities more limited. The new indexes underlying the PowerShares' Municipal Bond ETFs include both insured and uninsured municipal bonds. Merrill Lynch, Pierce, Fenner & Smith Incorporated ("BofA Merrill Lynch") will remain the index provider for each Fund.

Important Risk Information

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 Funds' returns may not match the return of the Underlying Indexes.

The Funds' underlying securities may be subject to call risk, which may result in the Funds having to reinvest the proceeds at lower interest rates, resulting in a decline in the Funds' income.

The Funds' 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.

There is no guarantee that the Funds' income will be exempt from federal or state income taxes.

Municipal insurance doesn't protect against losses in the Funds.

Municipal securities may be affected by political changes as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders. The market for municipal bonds may also be less liquid than for taxable bonds.

Puerto Rico's current economic problems increase the risk of investing in Puerto Rican municipal obligations, including the risk of potential issuer default, and also heighten the risk that the prices of Puerto Rican municipal obligations, and the Fund's net asset value, will experience greater volatility. Please see the prospectus supplement for complete information.

Investments in fixed-income securities, such as notes and bonds, carry interest rate and credit risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise and vice versa. Credit risk is the risk of loss on an investment due to the deterioration of an issuer's financial health.

PZA & PWZ

The Funds currently intends to effect creations and redemptions principally for cash, rather than principally in-kind because of the nature of the Funds' investments. As such, investments in the Funds may be less tax efficient than investments in ETFs that create and redeem in-kind.

PZT & PWZ

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

A natural or other disaster could occur in a geographic region in which the Funds invests, which could adversely impact the Funds' investments in the affected region.

Unlike most ETFs, the Funds currently intend to effect redemptions principally for cash and partially in-kind, rather than primarily in-kind redemptions because of the nature of the Funds' investments. As such, investments in Shares may be less tax efficient than investments in conventional ETFs.

PZT

New York's current economic problems increase the risk of investing in New York municipal obligations, including the risk of potential issuer default, and also heighten the risk that the prices of New York municipal obligations, and the Fund's net asset value, will experience greater volatility. Please see the prospectus supplement for complete information.

PWZ

California's current economic problems increase the risk of investing in California municipal obligations, including the risk of potential issuer default, and also heighten the risk that the prices of California municipal obligations, and the Fund's net asset value, will experience greater volatility. Please see the prospectus supplement for complete information.
