Exercise Administration
Optionees may exercise stock options on or after the vesting date; prior to the vesting date if exercise before vesting is allowed; or at any time during the life of the stock option, depending on the terms of your stock option plan.
When an optionee exercises a grant, you record the number of shares exercised, the funds and any applicable taxes due from the optionee, and issue the shares.
Depending on the type of option being exercised and the exercise method selected, you can issue the shares in a stock certificate, electronically deposit them with a stock broker, or hold the shares in escrow until the optionee meets restrictions, such as vesting.
