Was the CWT Form 4 a stock purchase or sale by the executive?

The Form 4 does not show open-market buying or selling. It reports a 548-share stock grant and multiple code F transactions where shares were withheld and surrendered to California Water Service Group to pay taxes triggered by vesting of restricted and performance stock awards.

After the reported equity award and related tax-withholding dispositions, Thomas A. Scanlon directly owns 5,783.135 shares of California Water Service Group common stock, according to the Form 4 totals following the final transaction date disclosed.

What triggered the tax-withholding share dispositions in the CWT filing?

The tax-withholding dispositions were triggered by the vesting of a Restricted Stock Award and a Performance Stock Unit award granted on March 7, 2023, which vested in full based on performance criteria and resulted in a 46% payout of the original performance goal.

What does the 46% payout in the CWT PSU award mean?

The Performance Stock Unit award vested based on performance criteria approved by the board. The filing states those criteria were met at a level that produced a 46% payout of the original goal, so fewer shares were delivered than the initial target amount.

What do code F transactions signify in the CWT insider report?

Code F in the Form 4 indicates shares delivered to the issuer to satisfy tax or exercise obligations. Here, multiple code F entries show California Water Service Group shares withheld and surrendered to cover tax liabilities from vesting restricted and performance stock awards.
