Stock options are not just a number of shares; they have various terms and conditions that affect their value and your ability to exercise them. When negotiating your stock options, it's important to understand the vesting schedule, exercise price, expiration date, and tax implications. The vesting schedule typically has a one-year cliff and monthly or quarterly vesting thereafter, though you may want to negotiate a shorter vesting period or a smaller cliff. The exercise price is usually equal to the fair market value of the shares on the date of the grant, though you may want to negotiate a lower exercise price if the company is not publicly traded or has a high valuation. The expiration date is usually 10 years after the grant date, but some companies may have shorter or longer periods; you may want to negotiate a longer expiration date if you plan to hold your options for a long time or if the company is not likely to go public or be acquired soon. Lastly, depending on the type of options and your holding period, you may face different tax rates and rules when you exercise them and when you sell the shares; consulting a tax professional or using a tax calculator can help you estimate your tax liability and plan your strategy accordingly.
