Under normal circumstances, the fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in the securities of underlying funds that, by the terms of their prospectuses, focus on making investments in issuers that are either based, operated or primarily operated in the U.S. or listed on a U.S. exchange or marketplace. The fund will generally invest approximately 75% of its net assets in underlying funds that are advised by Dimensional Fund Advisors LP and that provide the requisite portfolio exposure to specific investment factors.
