We have added functionality to facilitate the capture of stock option trades for public companies that occur with other brokers.

If you are a public company on the platform and have executives that trade via other brokers (through 10b5-1 plans or other trades) we now have an administrator-facing tool to enter in trade executions for stock options. The functionality allows for the calculation and adjustment of tax withholding information, and flows through to Carta’s reports. Additionally, reporting is available to assist your company in settling the off-platform trade with your executive’s external broker.

Upon selecting “Off System Transaction” at the employee grant level, administrators can now enter in trade execution information related to stock option transactions executed outside of Carta.

Selecting Off System Transaction brings you to the exercise information screen:

Taxes will be calculated based on the inputted trade information, and can be reviewed and adjusted if necessary.

Upon reviewing and approving, the transaction information will be stored as an off-system transaction, and the options available for exercise will be adjusted accordingly.
