Corporate Governance Specialist

This is an administrative disclosure reflecting reporting structure changes, not a trading decision.

The Schedule 13G/A clarifies that, in reliance on SEC Release No. 34-39538, The Vanguard Group no longer is deemed to beneficially own securities reported by its subsidiaries. The form lists 0% ownership and zero sole/shared voting and dispositive power.

Material impact depends on whether affiliated reporting entities disclose positions; the amendment itself does not indicate acquisitions, dispositions, or changes in economic ownership.
