Barclays Global Fund Advisors (the “Adviser”), the adviser to the iShares Funds, is being acquired by BlackRock, Inc. Upon the closing of the BlackRock transaction, the current investment advisory agreements between the Adviser and each iShares Fund will automatically terminate. As a result, iShares Funds shareholders, through a shareholder proxy proposal, are being asked to approve a new investment advisory agreement between the Adviser and each iShares Funds. In addition to the advisory agreement proposal, shareholders of the iShares Funds are being asked to elect a Board of Directors/Trustees of the iShares Funds and shareholders of certain iShares Funds are being asked to vote on an additional proposal at two separate shareholder meetings scheduled for November 4, 2009.

Please see the attached “Questions and Answers for Financial Advisers” for additional detail on the proposals. You may distribute the Q&A internally to your teams.

Beginning September 8, 2009, the iShares Funds will begin e-mailing and mailing proxy packages to shareholders with important information regarding these proposals.
