iShares Launches Two New Target Date ETFs that Expand the iShares Target Date Series

SAN FRANCISCO - August, 18, 2011 - BlackRock, Inc. (NYSE: BLK) today announced that its iShares® Exchange Traded Funds (ETFs) business, the world's largest manager of ETFs, has launched two new iShares ETFs on the NYSE Arca. The funds are the iShares S&P Target Date 2045 (NYSEArca: TZW) and iShares S&P Target Date 2050 (NYSEArca: TZY) Index Funds. The new funds provide a continuation of the existing iShares target series products, which are designed to provide investors with a diversified portfolio of iShares ETFs within an efficient ETF structure and can help investors prepare for an anticipated future need for funding a life event such as retirement.


"Implementing target date funds in retirement portfolios can be an increasingly attractive strategy for investors," said Chip Castille, Managing Director and head of BlackRock's U.S. and Canada Defined Contribution Group. "Target date products each offer a diversified, cost-effective way to help investors meet their investment needs. They also help mitigate common investor pitfalls such as poor asset allocation and failure to make portfolio changes over time, two actions that can reduce portfolio returns."


The two funds are benchmarked to the S&P Target Date 2045/2050 indices, which are designed to provide exposure to a diversified array of asset classes. The indices are rebalanced monthly, while on a yearly basis S&P conducts a survey of target date funds and derives an allocation strategy for the indices. S&P uses iShares ETFs to track each asset class.

Investing involves risk, including possible loss of principal.


Asset allocation models and diversification do not promise any level of performance or guarantee against loss of principal. Investment in the Funds is subject to the risks of the underlying funds.


Each fund has a number (a target date) at the end of the name that designates an approximate year when an investor plans to start withdrawing their money. The asset allocation of the Fund will become progressively more conservative as the specified target date approaches. An investment in the Funds is not guaranteed, and an investor may experience losses, including near, at or after the target date.


Transactions in shares of the iShares Funds will result in brokerage commissions and will generate tax consequences. iShares Funds are obliged to distribute portfolio gains to shareholders. Shares of the iShares Funds may be sold throughout the day on the exchange through any brokerage account. However, shares may only be redeemed directly from a Fund by Authorized Participants, in very large creation/redemption units.


The iShares Funds ("Funds") are distributed by SEI Investments Distribution Co. ("SEI"). BlackRock Fund Advisors ("BFA") serves as the investment advisor to the Funds. BlackRock Fund Distribution Company ("BFDC") assists in the marketing of the Funds. BFA and BFDC are affiliates of BlackRock, Inc., none of which is affiliated with SEI.
