Insights

Financial Analyst

TL;DR: Insider sold a meaningful block of shares while holding newly granted options, indicating portfolio rebalancing rather than increased ownership.

The Form 4 reports a sale of 82,910 Masco shares at a weighted average price of $76.0382, reducing direct holdings to 39,638 shares. Concurrently, Mr. Shah received three option grants totaling 82,910 options with exercise prices of $35.52, $42.13, and $33.75 and varying exercisable schedules. The option grants under the 2014 Long Term Stock Incentive Plan and the contemporaneous share sale offset each other in nominal share count terms. For investors, the transaction shows realized proceeds from previously held equity while maintaining long-term upside via stock options at substantially lower exercise prices than the sale price.

Corporate Governance Expert

TL;DR: Disclosure is complete and follows Rule 16 reporting; multiple option grants and a sizeable sale are documented with required footnotes.

The filing includes clear footnote disclosure that the sale price is a weighted average from multiple transactions and confirms the grants were made under the Masco 2014 Long Term Stock Incentive Plan and exempt under Rule 16b-3. The reporting is signed by a power of attorney and provides exercisability schedules for each option. From a governance perspective, the form meets reporting standards and supplies the detailed exercise and ownership figures necessary for stakeholder review.
