• Ownership Concentration: The purchase increases the director's holdings to 297,362.7 shares, which constitutes approximately 0.28% of the total shares outstanding. This is not a significant concentration of ownership.
• Dilution Impact: Not applicable, as this was an open market purchase, not an issuance of new shares.
