Insights

Corporate Governance Expert

TL;DR: Insider reported a non-sale disposition (gift) of 15,140 Westlake shares, reducing direct holdings to 39,741 shares.

The filing documents a Code G transaction, which is a gift rather than a market sale, and thus does not directly signal cashing out or market pressure. As Senior Chairman and a director, the change in direct holdings is material for disclosure but appears to be a routine ownership change. The timely filing and clear ownership balance are consistent with standard Section 16 reporting practices.

Securities Analyst

TL;DR: Reported disposal of 15,140 shares via gift leaves 39,741 shares held; no options or derivatives disclosed.

The Form 4 shows only a non-derivative disposal coded as G with no cash consideration (price $0). There are no accompanying derivative positions or other transactions listed. For investors, the transaction documents an ownership reduction by a named insider but provides no information on motives, valuation events, or impact on company fundamentals.
