   SHAREHOLDER UPDATE

SUCCESSFUL FIRST MEETING HOWEVER PARTICIPATION STILL NEEDED

Dear Fellow Shareholder,

The Special Meeting of Shareholders of the Dimensional Funds was held on Friday, May 8, 2015.    We are pleased to report that the response at this meeting was significant and overwhelmingly in favor.  In fact, we were able to approve the agenda items for many of the Dimensional Funds.   However, there are several Funds that require a higher level of participation in order to complete the shareholder meeting objectives.   Therefore, the Special Meeting has been adjourned to June 10, 2015, for such Funds, in order to seek additional support from you.  Since you have not voted on these important initiatives, we are asking you to take a minute of your time to consider these proposals and vote your shares using one of the convenient options below.

The proposals for which we are seeking your approval 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 strongly encourage you to vote your shares today.  Your vote will help us ensure that the Funds continue to serve your long-term investment needs

       Sincerely,

       David G. Booth

       Chairman and Co-Chief Executive Officer
