Impact Evaluation

• Market Cap Context: While Vanguard is a major holder, this specific filing represents a change in reporting entity structure rather than a cash-out transaction.
• Ownership Concentration: The filing indicates that The Vanguard Group Inc. itself no longer holds the shares, but they are likely held by subsidiaries which will report separately.
• Transaction Significance: The reduction to 0% is significant in number but low in economic impact regarding market supply/demand dynamics due to the administrative nature of the change.
