Insights

Financial Analyst

TL;DR: Insider sales of 15,051 shares were disclosed; transaction sizes and prices are explicit and represent a reduction in direct holdings.

The Form 4 shows routine insider selling rather than option exercises or derivative activity. Total shares sold equal 15,051 at weighted average prices of $106.50 and $106.90. After the sales, the reporting person still holds a material direct stake of 113,353 shares plus 2,460 shares indirectly in a 401(k) plan. There is no accompanying information on the reason for the sales or any planned trading arrangement disclosed on the form.

Corporate Governance Expert

TL;DR: Disclosure is complete for the reported trades; no derivatives or 10b5-1 plan is indicated on the face of the filing.

The filing identifies the reporting person as an officer (Chief Risk Officer) and indicates direct and indirect ownership post-transaction. The Form 4 includes clear transaction codes (S) for sale and provides weighted average prices and share counts. There is no amendment flag and the signature by attorney-in-fact is provided, satisfying filing formalities. The filing does not state any intent or planned selling program, so governance interpretation should be limited to the reported facts.
