Insights

Securities Analyst

TL;DR: CEO sold 82,103 shares at a weighted average of $65.1856; direct ownership remains 809,295 shares.

The Form 4 discloses a substantial insider sale by the company's Chairman and CEO totaling 82,103 shares executed in multiple transactions at prices between $65.02 and $65.38, with a reported weighted average price of $65.1856. The filing is specific about post-transaction direct ownership and identifies several indirect holdings, including spouse-held shares and units in the issuer's retirement plan. For investors, the filing increases transparency around insider holdings and recent liquidity actions, but the form does not state the reason for the sale or indicate any contractual plan that would explain timing.

Corporate Governance Expert

TL;DR: Clear Form 4 disclosure of insider disposition and indirect holdings; no contractual plan or explanation is shown.

The disclosure meets reporting requirements by listing the transaction date, quantity sold, weighted average price, and resulting beneficial ownership. It also clarifies the existence of indirect holdings via spouse and employee benefit plan units and offers to provide granular price-by-price sale details. The filing does not indicate a 10b5-1 plan or similar written plan for the sales, nor does it provide narrative reasons for the disposition; governance reviewers would note completeness of figures but may seek confirmation whether sales were pre-arranged or discretionary.
