Dear iShares Shareholder,

By now, you should have received a proxy package via email regarding two important shareholder meetings of the iShares® Funds. According to our records, we have not yet received your vote on the proposals presented for shareholder approval, or, if you own multiple iShares Funds, you have not yet voted all the shares you own.

Barclays Global Fund Advisors, the adviser to the iShares® Funds, is being acquired by BlackRock, Inc. The Board of Directors of iShares, Inc. and the Board of Trustees of iShares Trust recommend that shareholders vote in favor of each of the proposals.

PLEASE VOTE TODAY to avoid future proxy correspondence and to ensure that your iShares Fund receives enough votes to act on the proposals.

We’ve provided three easy ways to cast your vote:
