Insights

Investment Governance Expert

Passive adviser holdings at the 5% threshold highlight standard index/quant exposure, not control intent.

The filing shows an aggregated position of 915,049 shares, equal to 5.0% of the class, held across funds for which Dimensional provides advisory services. The statement that the securities are "owned by the Funds" and that Dimensional "disclaims beneficial ownership" is consistent with asset managers reporting aggregated positions while attributing underlying legal ownership to client vehicles.

Key dependencies are the composition of the underlying Funds and their investment mandates; because the filing asserts the position is held in the ordinary course and not to influence control, near‑term governance actions are unlikely. Monitor any future amendments that would show increased voting coordination or a rise above the 5.0% threshold.

Portfolio Manager

Voting and dispositive powers are concentrated within Dimensional’s advisory role, reflecting portfolio-level decision authority.

The schedule reports sole voting power over 887,817 shares and sole dispositive power over 915,049 shares, with no shared powers disclosed. That pattern aligns with a manager executing trading and proxy instructions for client accounts rather than a single beneficial owner directing strategy.

Practical items to watch include any subsequent filings showing changes in the number of shares, voting power breakdowns, or a shift from passive to active intent; such changes would be material to investors and could alter stewardship expectations.
