"The acceptance of iShares Funds within the Mexican investment community has been strong, and we're pleased to provide Mexican investors with the additional trading capability of style and sector investing," said Daniel Gamba, Managing Director of the Latin America Institutional Business for BGI. "Growth and value investing as well as sector investing through iShares Funds provides Mexican investors an additional vehicle to express their investment views."

The application of style and sector investing has grown in importance as institutional investors are increasingly underweighting or overweighting positions according to tactical strategy or technical indicators. The trading flexibility, transparency and efficiency of iShares allow professional investors to implement a comprehensive range of strategies.

"We feel that style and sector investing with iShares ETFs provides an elegant solution to leverage investment insights and implement portfolio allocation decisions," continues Gamba. "Each fund is designed to represent the characteristics of an asset style or market sector as precisely as possible."

The availability of iShares Funds in Mexico reflects a regulatory change in the regime that permits certain qualified Mexican investors, primarily institutions, to take advantage of investment opportunities, such as ETFs and other foreign securities that trade through the Mercado Global platform. Afores, for example, are allowed to invest in these four style index iShares through the Mercado Global platform.

In Mexico, iShares can be bought and sold by qualified investors via any broker-dealer who is a member of the Bolsa Mexicana de Valores. The shares clear and settle through the Mexican Stock Exchange's normal clearance and settlement process, and then are purchased or sold from a sub-account at U.S.-based DTC maintained on behalf of the iShares sponsoring broker in Mexico, Deutsche Bank Securities. For the Mexican investor, the process is expected to be seamless.

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.

Investing involves risk, including possible loss of principal. In addition to the normal risks associated with investing, narrowly focused investments typically exhibit higher volatility. Transactions in shares of the iShares Funds will result in brokerage commissions.
