Employee Stock Option
Also written ESOP terminology · Stock option (employee)
The right, not the obligation, given to an employee to buy company shares at a fixed price after a minimum one-year vesting period — the RTA administers the grant; tax treatment is a separate topic.
In plain language
A company can reward its employees with more than a salary. It can give them the right to buy its own shares later, at a price fixed today. That right is an Employee Stock Option.
It is a right, not a promise of shares outright. The workbook is precise about this: the option gives the employee the benefit or right to purchase or subscribe for shares at a future date, at a pre-determined price. Nobody is forced to exercise it.
How it works
The workbook sets out the vocabulary an RTA works with:
- Stock option — the right itself, not a share.
- Vesting period — the waiting period before the option can be exercised. The workbook prescribes a minimum vesting period of 1 year. The employee must stay with the company through this period to become eligible.
- Exercise period — the window during which the employee can convert the option into shares.
- Exercise price / grant price / strike price — the pre-determined price the employee pays.
- Expiration date — the last date the option can be exercised; after this it lapses.
Separately, the Finance Act, 2020 amended the Income-tax Act to defer the collection of tax on the ESOP perquisite, but only for eligible start-ups. The registrar's job stops at administering the grant, the vesting register and the exercise-to-allotment process; the tax computation itself is a distinct topic.
A worked example
Northgate Software Ltd grants 5,000 options to a senior engineer on 1 April 2023, at an exercise price of Rs 80 against a market price of Rs 210 that day, with the workbook's minimum 1-year vesting period.
The options vest on 1 April 2024. The engineer's exercise window runs for two years after that, to 31 March 2026. She exercises 3,000 options on 15 January 2025, paying 3,000 × Rs 80 = Rs 2,40,000 to the company, and the RTA processes the allotment of 3,000 shares to her demat account.
The remaining 2,000 options lapse unexercised if she leaves before exercising them or lets the window run past 31 March 2026 — the expiration date extinguishes the right entirely, with no refund of anything, because nothing was paid for the option itself.
Why NISM asks about it
Chapter 8, section 8.4 (Employee Stock Options). Expect the minimum 1-year vesting period and the five pieces of ESOP vocabulary — vesting, exercise period, exercise/grant/strike price, expiration date. The perquisite and capital-gains tax computation on ESOPs is covered in depth under Series X-B's Employee Stock Option Plan page, not here.
Common exam traps
- The option is a right, not shares. Nothing is owned until exercise and allotment.
- Minimum vesting is 1 year — a shorter period offered by a company would not meet the workbook's stated minimum.
- This page is the mechanism (RTA administration); the tax computation on exercise and sale is a separate paper's subject — do not mix the two when answering a tax-flavoured question.
- The start-up tax deferment under the Finance Act, 2020 postpones tax; it does not remove it, and only eligible start-ups qualify.
Where this is taught
Free preparation for NISM Series II-ARelated terms
- Employee Stock Option PlanA right, not an obligation, for an employee to buy employer shares at a pre-fixed price — taxed twice: as a salary perquisite on exercise, and as capital gains on eventual sale.
- Identified PersonsThe select group a company names to receive a private placement under Section 42 — capped at 50 allottees a year excluding QIBs and ESOP employees, with allotment within 60 days or a mandatory refund.
- Preferential allotment lock-inThe mandatory holding period on shares from a preferential allotment by a listed company — 18 months for promoters and the promoter group, 6 months for everyone else, both from the date of trading approval.
- Option poolThe block of shares a company sets aside for employee stock options — its size matters to an investor because every option exercised dilutes the investor's stake.
