IMPORTANT NOTICE

Dear Shareholder:

We recently announced that we will be hosting a Special Meeting of Shareholders for all of the Dimensional Funds.  This meeting is scheduled for May 8, 2015 at 9 a.m. Central Time and will be held at the Funds’ offices here in Austin, Texas.  At the Meeting, shareholders will be presented with several proposals for their consideration which are designed to increase efficiencies, update certain investment limitations, and create uniformity across all Funds.  While the Dimensional Funds’ Boards firmly believe these proposals are in the best interests of all shareholders, it is you, the shareholder, who must approve them.

We offer multiple ways for you to cast your say on these matters so your voice will be heard at the meeting.  Simple instructions to do so are found below and on the enclosed voting form.  Remember, voting your proxy will help the Dimensional Funds achieve these efficiencies in the most time sensitive and cost efficient way.  If you would like to view these proposals in detail, you can find the statement at us.dimensional.com.  Once there, simply click on the “2015 Proxy Vote” link.

       Sincerely,

       David G. Booth

       Chairman and Co-Chief Executive Officer
