ISOs: Basics

What are the top 10 questions I should ask about my stock options?

You should know the answers to the following questions. Understanding the topics involved will help you make the most of your stock options and prevent costly mistakes.

1. What type of stock options do I have?

2. Is formal acceptance of the grant required? What happens if I don't accept the grant before exercise?

3. What is the vesting schedule?

4. How long is the term of the stock options?

5. What is the deadline for exercising the options to prevent the expiration of the grant?

6. What would happen to the stock options if I were to leave or lose my job, die, become disabled, or retire? How do these events affect vesting and the expiration date of the option grant?

7. How do I exercise the stock options?

8. After I exercise my options, in what account will the shares or cash proceeds appear?

9. How does the tax withholding work? What are the tax rates for NQSOs? (There is no withholding for ISOs.)

10. What would happen to vested stock options in a corporate acquisition or merger? What if my stock options have not yet vested when the corporate change in control happens?

In addition, you should understand the tax treatment of the options you have. Nonqualified stock options and incentive stock options are taxed differently. You should also learn about the related tax return reporting. This website's Tax Center covers all tax topics involving stock compensation.
