Compliance & Regulatory Specialist

Filing complies with disclosure rules and includes standard disclaimers about beneficial ownership.

The statement clarifies Dimensional is an investment adviser and disclaims beneficial ownership because the securities are owned by advised Funds. The Schedule 13G certification asserts the shares were not acquired to influence control, consistent with Rule 13d-1(b) filings for passive holders.
