Barclays Global Investors Announces the Trading of the First U.S. Listed Municipal Bond Exchange Traded Fund

SAN FRANCISCO, CA--(Marketwire - September 10, 2007) - Barclays Global Investors (BGI) announced that the iShares S&P National Municipal Bond Fund (AMEX: MUB) will begin trading today on the American Stock Exchange. It is the first municipal bond ETF available to U.S. investors. The Fund is designed to track a liquid, institutional quality municipal bond index and its annual expense ratio is 0.25%*.

"Investors have been looking for a simple and cost-effective method of gaining exposure to the municipal market, which is traditionally a less liquid and expensive marketplace especially for those building a portfolio of individual issues," said Noel Archard, Head of U.S. iShares Product Development. "The iShares S&P National Municipal Bond Fund looks to solve those problems. BGI applied its quantitative investment management expertise to deliver what it believes is a quality municipal ETF accessible to investors."

The S&P National Municipal Bond Index™ includes bonds from issuers that are primarily state or local governments or agencies such that the interest in the bond is exempt from U.S. federal income taxes. Each bond must have a rating of at least BBB- and must have a minimum par amount outstanding of $50 million.

The iShares Funds are index funds that are bought and sold like common stocks on securities exchanges. The iShares Funds are attractive to many individual and institutional investors and financial intermediaries because of their relative low cost, tax efficiency and trading flexibility. Investors can purchase and sell shares through any brokerage firm, financial advisor, or online broker, and hold the funds in any type of brokerage account.

Carefully consider the funds' investment objectives, risk factors and charges and expenses before investing. This and other information can be found in the funds' prospectuses, which may be obtained by calling 1-800-iShares or by visiting www.ishares.com. Read the prospectus carefully before investing.
