Insights

Equity compensation and governance analyst

These are routine tax-withholding dispositions tied to RSU vesting, not open-market selling.

The transactions show Kenneth Best, Chief Accounting Officer of Fiserv Inc., delivering shares to satisfy tax liabilities when restricted stock units vested. The Form 4 uses code F, and the footnote confirms the shares were withheld for tax payment, a standard equity-compensation mechanism.

Because the dispositions are not discretionary open-market sales, they provide limited insight into management’s view of the stock. Following these events, Best’s direct holdings remain sizable at 65,117 shares, so the filing mainly documents normal administrative treatment of equity awards rather than a change in investment stance.
