Reported holdings are characterized by shared voting and dispositive power only, with no sole control reported. The joint filing and powers of attorney document coordination between the individual and the corporate holder. For investors, a >5% disclosure is material because it signifies a concentrated stake that can influence corporate actions, even if formal sole control is not asserted.

Corporate Governance Expert
