To make employees more committed towards the development of the company, they are offered certain benefits. Other than insurance and performance bonuses, the company provides stock options.
In this blog, you will learn in detail what stock options are, their types, eligibility criteria, and how they work.
Companies offer certain benefits to employees to boost their performance. One of these benefits is providing equity compensation. When a company provides stock options to its employees, it gives them an ownership stake and makes them a part of the company’s growth and success. This encourages employees to give their best, as they see the organization’s success as their own, with an opportunity to gain monetary benefit.
Stock options are often offered by start-ups and financially strong companies like Infosys and Wipro. The employees have to fulfil certain eligibility criteria set by the company to avail this perk.
In stock options, the employee can purchase shares of the company at a certain price within a specified period. The employees have to work with the company for a specified period to be eligible.
There are two main types of stock options.
ISOs provide tax benefits to the employee, where they don’t have tax liability on the grant or exercise price of the stock. To receive ISO, employees must fulfill a specified holding period and other eligibility criteria.
Unlike ISOs, NSOs are offered not only to regular employees but also to executives and consultants working with the company. NSOs are taxable as ordinary income tax upon exercise. In NSOs, employees have a say regarding the terms and conditions applicable.
RSUs are the right given to employees to receive the shares at a future date, provided that the employees fulfil certain conditions. RSUs don’t require upfront payment and can be given after a period of time or upon good performance.
In the case of ISOs, only permanent employees are eligible for the stock options.
For NSOs, permanent employees, non-independent directors, and contract-based workers are eligible.
Here's how stock options work
Granting of options The company grants employees stock options, and they can buy the company’s shares at a predetermined price.
Vesting period Employees can avail themselves of stock options when they remain with the company for a specific period. After the set period, employees are eligible to exercise their stock options.
Exercise price Exercise price is a predetermined price at which employees buy stock options when they are eligible for stock options.
Expiration date Stock options have an expiration date, the employees have to exercise their stock options before the expiration date.
Profit The reason stock options are provided is so that employees can participate in the growth of the company. When the share price of the company increases, the value of the stock options also increases. When the share price is above the exercise price, the employee can sell the shares and book a profit.
