• Price and amount: 1,491 shares at $61.08 each; proceeds ≈ $91,070.
• Shares owned after transaction: Not stated in the provided filing excerpt.
• Footnote (F1): These were automatic "sell-to-cover" broker sales to cover withholding taxes upon award vesting and share delivery. The reported price is a weighted average from multiple trades in a block; the filer offers to provide a breakdown of sales prices per trade on request.
• Transaction code: S = Sale (not a purchase or exercise).

Context

• "Sell-to-cover" sales are routine tax-withholding transactions tied to award vesting and do not necessarily signal the insider’s view on the company. This filing documents the mechanics of covering withholding obligations rather than an independent open-market investment decision.
