The California Stock Option Plan is a comprehensive stock option program that allows companies in California to offer various types of stock options to their employees. This plan creates opportunities for companies to incentivize their workforce through the grant of Incentive Stock Options (SOS), Nonqualified Stock Options (SOS), and Exchange Options. Incentive Stock Options, commonly known as SOS, are a specific type of stock option that provides tax advantages to the employee. These options are typically offered to key employees and can only be exercised within a certain period after being granted. SOS provide preferential tax treatment, as any gains made upon exercise are eligible for long-term capital gains tax rates. Nonqualified Stock Options, also known as SOS or Nests, are a more flexible type of stock option that can be offered to both employees and non-employees. Unlike SOS, SOS do not qualify for preferential tax treatment. Upon exercise, the employee incurs immediate tax liability on the difference between the fair market value of the stock and the exercise price. Exchange Options, also referred to as Reload Options or Reload Grants, are a unique feature of some stock option plans. These options provide employees with the opportunity to exchange some or all of their exercised options for new stock options. This allows employees to potentially extend the exercise period or to benefit from additional grants. The California Stock Option Plan is designed to meet the varying needs of companies and employees by offering different types of stock options. By implementing this plan, companies can attract and retain talented individuals by providing them with a stake in the company's success. Furthermore, employees can benefit financially through the potential appreciation of the company's stock value.
