- On the same date he forfeited/surrendered 1,259 shares (744 + 345 + 170) to satisfy tax withholding obligations at the closing price of $155.18, which represents a surrender value of $195,372. These were tax-withholding share forfeitures related to the vesting of prior service RSUs.
Key Details
- Transaction date: May 15, 2026. Tax-withholding price used: $155.18 per share.
- Grants: two RSU awards of 3,504 shares each (total 7,008 RSUs) issued under the 2012 Equity Incentive Plan.
- Shares surrendered for tax withholding: 1,259 shares (value $195,372).
- Footnotes: grants are restricted RSUs subject to time- and/or performance-based vesting (one grant includes performance-based RSUs that may pay 0–200% based on relative TSR for 2026–2028; service RSUs vest one‑third per year over 2027–2029). Several post-vesting amounts remain subject to forfeiture (examples noted in the filing: 19,967; 21,221; 21,934; 20,871; 23,471 shares tied to various grants).
- Filing timeliness: the filing does not indicate a late report.
Context
- These transactions reflect award grants and routine tax-withholding share forfeitures on RSU vesting, not open-market sales or purchases. Surrendering shares to cover taxes is a common, administrative step when RSUs vest and does not necessarily signal a change in insider sentiment.
- One of the grants is performance-based and vests (if earned) after measurement of relative total shareholder return for the 2026–2028 performance period, with vesting (if earned) in 2029.
