Insights

Equity compensation and insider-transactions analyst

Filing shows routine equity awards and tax withholding, not open-market trading.

The transactions for Christine A. Leahy involve a small grant of 363.77 CDW common shares as dividend equivalents on existing restricted stock units and 4,872.52 shares withheld to cover tax liabilities on a previously granted award. Both are standard features of long-term incentive plans.

No open-market purchases or sales occurred, and the Form 4 shows Leahy continuing to hold 188,505.57 shares directly plus 17,250 shares indirectly through a family gift trust. The scale of the tax withholding is modest relative to her total holdings, reinforcing that this is routine compensation and tax administration rather than a discretionary change in exposure.
