Regulatory & Market Context

• Rule Designation: Filed pursuant to Rule 13d-1(b) as an institutional investment adviser.
• Exit Below 5% Threshold: Because Vanguard's ownership declined below the 5% threshold to 4.97%, this filing serves as an amendment formally disclosing the drop below statutory major-shareholder reporting levels.
• Market Impact: While large institutional rebalancings of index and passive sleeves frequently shift holdings slightly above or below the 5% threshold without signaling active management dissatisfaction, the filing indicates a modest net reduction in aggregate shares held by the institution.
