ESOP Valuation in India under Ind AS 102: Methodology, Graded vs Cliff Vesting, and a Worked Example

Employee stock options are the most widely used long-term incentive in Indian companies – and among the most frequently mis-valued. This guide sets out what Ind AS 102 requires, how each Black-Scholes input is actually derived for an Indian company, and where graded vesting quietly changes both the amount and the timing of the expense. It includes a live engagement walkthrough and a full numerical illustration.

The three different ESOP valuations – and why they get confused

Before any methodology, a distinction that resolves most of the confusion we encounter. The word “ESOP valuation” in India refers to at least three different exercises, performed at different dates, for different regulators, and sometimes by different professionals. They are not interchangeable, and one report will not serve all three purposes.

	Accounting valuation	Perquisite tax valuation	Regulatory / transaction valuation
Why it is done	To measure the employee benefit expense in the financial statements	To compute the perquisite taxable in the employee’s hands on exercise	For issue of shares, regulatory filings, buybacks, or transfer of securities
Governing framework	Ind AS 102 (or the ICAI Guidance Note for companies not on Ind AS)	Section 17(2)(vi) of the Income-tax Act, read with Rule 3(8) of the Income-tax Rules	Companies Act 2013, SEBI regulations, FEMA pricing guidelines, as applicable
What is valued	The option, at grant date	The share, on the date of exercise	The share, at the relevant transaction date
Valuation date	Grant date – fixed, never remeasured	Exercise date (for unlisted shares, a merchant banker report dated within 180 days before exercise is permitted)	As prescribed for the relevant transaction
Who typically prepares it	An independent valuer; auditors expect a registered valuer’s report	A SEBI-registered Category I Merchant Banker, where shares are unlisted	A Registered Valuer under Section 247, where the law so requires

This article deals with the first of the three – the accounting valuation under Ind AS 102. If you are looking for the perquisite computation at the point of exercise, that is a separate exercise on a separate date, and the number from your Ind AS 102 report will not be the number you need.

What Ind AS 102 requires

Ind AS 102, Share-based Payment, applies whenever a company receives goods or services in exchange for its own equity instruments. An ESOP grant to employees is the textbook case: the company receives service, and pays for it in options rather than cash.

Four principles drive everything that follows.

• Measure the instrument, not the service. The award is measured at the fair value of the equity instruments granted, not at the fair value of the services received, because employee services cannot be measured reliably on their own.
• Fix the value at grant date. Fair value is determined once, at the grant date. Movements in the share price afterwards do not change it. A grant valued in a rising market stays valued at its grant-date figure.
• Recognise over the vesting period. The grant-date fair value is charged to profit or loss over the period the employee must serve to earn the award, with a matching credit to a share-based payment reserve within equity. The charge is non-cash but it is real, and it reduces reported profit.
• Never remeasure for market movements – only for expected vesting. Fair value is not remeasured for share price movements. It is, however, adjusted for the number of options expected to vest, which is re-estimated at each reporting date.

Options have no observable market price, so fair value has to be derived using an option pricing model. For a standard ESOP with a defined exercise window and no exotic terms, the Black-Scholes-Merton model is accepted and is what we apply. Where an award carries market-based performance conditions or path-dependent features, a binomial lattice or Monte Carlo simulation becomes the more appropriate choice.

The six Black-Scholes inputs, derived for an Indian company

The model itself is arithmetic. The valuation work is in defending each of the six inputs – which is also what an auditor will test.

1. Share price at grant date (S)

For a listed company, the starting point is the traded price. But a single day’s closing price is a poor input where trading is thin or irregular, because one low-volume session ends up driving the entire expense. Our preference in such cases is a volume-weighted average price over a defined lookback period – total traded value divided by total traded quantity – which reflects where volume actually changed hands.

For an unlisted company, there is no market price, and the share itself must be valued first, typically using a discounted cash flow method, a market approach based on comparable companies or transactions, or an asset-based approach, selected according to the stage and nature of the business. Only once the equity value per share is established can the option be valued.

2. Exercise price (K)

A contractual fact taken from the approved ESOP scheme and grant letters, reconciled to the board and shareholder approvals. No estimation is involved, but it should be verified against source documents rather than assumed from a summary schedule.

3. Expected life (t)

The input most often applied incorrectly. Expected life is neither the vesting period nor the contractual life. An employee cannot exercise before vesting and will not exercise after expiry, so the exercise window runs from the vesting date to the end of the exercise period.

Where a company has its own reliable history of employee exercise behaviour, that history is the best evidence. Most Indian companies granting options for the first time do not have it, and the midpoint (simplified) method is then widely accepted: expected life equals the midpoint of the earliest and latest possible exercise dates, measured from the grant date.

4. Risk-free rate (r)

The yield on Government of India securities as at the grant date, taken at the tenor matching the option’s expected life. The sovereign par yield curve published by Financial Benchmarks India Pvt. Ltd. (FBIL) is the appropriate reference, and the annualised yield-to-maturity should be read at the matching tenor.

Two errors are common here. The first is using a single ten-year benchmark for every option regardless of its life, which overstates the rate on shorter-dated tranches when the curve is upward sloping. The second is reading the curve as at the date the report is being prepared rather than as at the grant date.

5. Expected volatility (σ)

Ind AS 102 looks first to the historical volatility of the entity’s own shares, measured over a period commensurate with the expected life of the option. For a listed company with adequate trading history, that is the primary and strongest reference: daily logarithmic returns, standard deviation of those returns, annualised over the number of trading days in a year.

A sector index is the weaker choice and should not be used where own-share data exists. An index is a diversified portfolio, and diversification removes precisely the company-specific risk that drives a single stock’s volatility – so index volatility structurally understates the figure and understates the option value with it. An index is defensible only as a cross-check.

For an unlisted company, no own-share history exists. The accepted approach is the median historical volatility of a set of listed comparable companies, selected on business similarity and size, measured over a window matching the expected life. The peer set and the basis of selection should be disclosed in the report.

6. Expected dividend yield (q)

Determined by whether option holders are entitled to dividends before exercise and by the company’s dividend history and stated policy. Where holders have no such entitlement and the company has no established dividend track record, a nil yield is appropriate – but the basis should be documented rather than left as a silent assumption in the model.

Engagement walkthrough: a listed company with graded vesting

The following is drawn from a completed engagement. Client identity and all monetary figures have been withheld; the methodology and judgements are reproduced as applied.

Three features made the engagement non-routine, and each maps to one of the inputs above.

• Graded vesting. Ind AS 102 treats each instalment of a graded award as a separate grant. Three tranches meant three option valuations – each with its own expected life, risk-free rate and volatility estimate.
• Thin trading. The shares traded, but not deeply and not at meaningful volume every day. We used a volume-weighted average price across twelve months of exchange data rather than a single closing price, so that thin sessions could not distort the expense.
• Tenor matching. With annual vesting and a three-year exercise period, the midpoint method produced expected lives of 2.5, 3.5 and 4.5 years for the three tranches. Every subsequent input was then matched to those three horizons.

The risk-free rate was read from the FBIL sovereign curve at 2.5, 3.5 and 4.5 years as at the grant date, giving three distinct rates in a band of roughly 6.5% to 6.9%. Volatility was computed from the company’s own daily price series, with a different lookback window for each tranche matching that tranche’s expected life. Dividend yield was nil, the scheme carrying no pre-exercise dividend entitlement.

The fair value per option rose from Tranche 1 to Tranche 3 – longer expected life means more time value and a larger discount on the exercise price, and that effect outweighed the slight easing in volatility over the longer measurement windows. The deliverable included a tranche-wise amortisation schedule the finance team could post directly, and a working file structured so that any figure in the report could be traced to source. The audit review of the ESOP charge closed without a second round of queries.

Graded vs cliff vesting: a worked example with numbers

To show how much the vesting pattern alone changes the answer, here is a hypothetical grant valued twice – identical in every respect except how it vests. All figures below are illustrative and do not relate to any client.

Parameter	Assumption (constant across both scenarios)
Options granted	1,20,000
Share price at grant (S)	₹100
Exercise price (K)	₹100
Expected volatility (σ)	40% per annum
Expected dividend yield (q)	Nil
Exercise period	3 years from each vesting date
Risk-free rate (r)	6.50% at 2.5 years, 6.70% at 3.5 years, 6.90% at 4.5 years

Scenario	Vesting pattern
Scenario A – Cliff (non-graded)	All 1,20,000 options vest at the end of Year 3
Scenario B – Graded	40,000 options vest at the end of each of Years 1, 2 and 3

Step 1 – Expected life

Scenario / tranche	Vests at	Window ends	Expected life
Scenario A – Cliff (all options)	Year 3	Year 6	4.5 years
Scenario B – Tranche 1	Year 1	Year 4	2.5 years
Scenario B -Tranche 2	Year 2	Year 5	3.5 years
Scenario B – Tranche 3	Year 3	Year 6	4.5 years

Tranche 3 of the graded grant carries the same expected life as the whole cliff grant, because they vest on the same date. The difference is that under cliff vesting all 1,20,000 options carry that 4.5-year life, while under graded vesting only 40,000 do.

Step 2 – Fair value per option and total cost

Scenario	Options	Expected life	Fair value per option	Cost
Scenario A – Cliff	1,20,000	4.5 years	₹43.58	₹52,29,600
Scenario B – Tranche 1	40,000	2.5 years	₹31.18	₹12,47,200
Scenario B – Tranche 2	40,000	3.5 years	₹37.78	₹15,11,200
Scenario B – Tranche 3	40,000	4.5 years	₹43.58	₹17,43,200
Scenario B – Graded, total	1,20,000			₹45,01,600

First insight: the graded grant costs less in total. ₹45,01,600 against ₹52,29,600 – about 14% lower – with the same number of options, the same strike price and the same share price. Two-thirds of the graded options carry a shorter expected life, and shorter-dated options are worth less. Applying a single value of ₹43.58 across the graded grant would overstate Tranches 1 and 2 by 40% and 15% respectively.

Step 3 – Year-wise expense

Scenario A has one vesting period, so the cost is spread evenly across it. Scenario B requires each tranche to be recognised over its own vesting period, all three running from the grant date.

Scenario A -Cliff	Year 1	Year 2	Year 3	Total
Expense for the year	₹17,43,200	₹17,43,200	₹17,43,200	₹52,29,600
% of total recognised (cumulative)	33.3%	66.7%	100.0%

Scenario B – Graded	Year 1	Year 2	Year 3	Total
Tranche 1 – over 1 year	₹12,47,200	–	–	₹12,47,200
Tranche 2 – over 2 years	₹7,55,600	₹7,55,600	–	₹15,11,200
Tranche 3 – over 3 years	₹5,81,067	₹5,81,067	₹5,81,066	₹17,43,200
Expense for the year	₹25,83,867	₹13,36,667	₹5,81,066	₹45,01,600
% of total recognised (cumulative)	57.4%	87.1%	100.0%

Second insight, and the one that catches finance teams out: the graded grant costs less overall but costs far more in Year 1. ₹25,83,867 against ₹17,43,200 – roughly 48% higher. By the end of Year 1 the company has recognised 57.4% of the graded grant’s cost against 33.3% of the cliff grant’s.

Step 4 – What the common shortcut produces

Suppose the graded grant were valued as a single option at ₹43.58 and expensed straight-line over three years, which is the treatment we most often find in workings prepared without tranche-level analysis.

	Year 1 expense	Total cost
Correct treatment – tranche-wise	₹25,83,867	₹45,01,600
Common shortcut – single value, straight-line	₹17,43,200	₹52,29,600
Misstatement	Year 1 understated by ₹8,40,667	Total overstated by ₹7,28,000

Both the amount and the timing are wrong, and they are wrong in opposite directions – which is exactly why the error survives a summary review. The total looks conservatively high while the first year looks comfortably low.

Recognising the expense, and the accounting entries

The entries are identical in form under both vesting patterns; only the amounts and their timing change. In each year of the vesting period:

• Employee benefits expense (share-based payment)  –  Debit
  
• Share-based payment reserve (equity)  –  Credit

On exercise, the amount received from the employee is recorded together with the share-based payment reserve balance attributable to the exercised options, credited to share capital at face value with the balance to securities premium.

Where vested options lapse unexercised, the expense already recognised is not reversed – the service was rendered and the cost was incurred. The reserve balance is generally transferred within equity, to general reserve or retained earnings, in line with the company’s stated accounting policy.

Forfeitures, lapses and the annual true-up

The grant-date fair value per option is fixed. What is revised at each reporting date is the estimated number of options expected to vest, based on service conditions and non-market performance conditions, with the cumulative expense trued up accordingly. This is an estimate revision, not a revaluation, and it is a point auditors test.

Graded vesting adds a practical burden here. Under cliff vesting, an employee who resigns in Year 2 forfeits the entire award and the whole cumulative expense for that employee reverses. Under graded vesting, the same resignation leaves Tranche 1 already vested and untouched, while Tranches 2 and 3 are forfeited. The reversal is partial and has to be computed tranche by tranche – which means the schedule must be maintained at tranche level for the full vesting period, not merely at grant level.

Where Ind AS 102 parts company with US GAAP

ASC 718 permits an entity to elect, as an accounting policy, to recognise the cost of a graded award with only service conditions on a straight-line basis over the total vesting period. Ind AS 102 offers no equivalent election – the accelerated, tranche-wise attribution is mandatory.

This matters more than it might appear. ESOP templates and group accounting manuals built for a US parent routinely carry the straight-line assumption into an Indian subsidiary’s books, where it is simply not available. If your working paper spreads a graded grant evenly across the vesting period, that is the first thing to check.

What has to be disclosed

Ind AS 102 requires disclosure sufficient for a reader to understand the nature and extent of share-based payment arrangements, how fair value was determined, and the effect on profit and financial position. In practice, the valuation report should give the finance team everything needed for:

• a description of each arrangement, including vesting terms, exercise period and settlement method;
  
• the number and weighted average exercise price of options granted, exercised, forfeited, lapsed and outstanding during the year;
  
• the weighted average fair value of options granted during the year;
  
• the option pricing model used and each input to it – share price, exercise price, expected volatility, expected life, risk-free rate and expected dividends – together with how each was determined, and specifically how expected volatility was estimated;
  
• the total expense recognised for the year and the carrying amount of the share-based payment reserve.

The line auditors most often query is how expected volatility was determined. A report that names the data source, the observation window, the return frequency and the annualisation basis answers it before it is asked.

Nine mistakes we see in ESOP workings

1. Valuing a graded grant as a single option. Each instalment of a graded grant is a separate grant under Ind AS 102. Three tranches require three fair values.
   
2. Using the vesting period or contractual life as expected life. Expected life is the midpoint of the exercise window measured from the grant date, not the time to vesting and not the contractual expiry.
   
3. Applying one ten-year benchmark rate to every tranche. On an upward-sloping curve this overstates the rate on shorter tranches. Read the yield at the matching tenor.
   
4. Reading the yield curve as at the report date. Inputs must be as at grant date. A curve read months later is the wrong curve.
   
5. Using a sector index for volatility when own-share data exists. An index diversifies away company-specific risk and understates single-stock volatility. Use it only as a cross-check.
   
6. Mismatching the volatility window to the expected life. A 4.5-year option valued on six months of price history is not measured over a commensurate period.
   
7. Straight-lining a graded grant. Permissible under US GAAP by election; not available under Ind AS 102. The profile must be front-loaded.
   
8. Tracking forfeitures only at grant level. The true-up must run tranche by tranche, or vested and unvested portions get treated alike.
   
9. Leaving dividend yield unexplained. A blank cell in the model is an undocumented assumption. State the basis, even when the answer is nil.
   

Who should prepare an ESOP valuation in India

For the accounting valuation under Ind AS 102, the standard does not itself name a category of professional. What it requires is a fair value determined on a reasonable and supportable basis. In practice, auditors expect an independent valuation report from a qualified valuer, and a report from a Registered Valuer registered with the IBBI under Section 247 of the Companies Act, 2013 carries the weight that expectation is looking for.

For the perquisite tax valuation of unlisted shares at the point of exercise, the requirement is specific: the fair market value must be determined by a Category I Merchant Banker registered with SEBI. A Registered Valuer’s report does not substitute for it. Listed companies follow the prescribed rule based on exchange prices on the exercise date and do not need a separate report.

Where a valuation is required for issue or transfer of securities, the applicable framework – the Companies Act, SEBI regulations or FEMA pricing guidelines – dictates who may sign, and the requirements differ. It is worth confirming the purpose before commissioning the report, because a report addressed to the wrong purpose is rarely reusable.

Frequently asked questions

1. Is an ESOP valuation mandatory in India?

For any company recognising a share-based payment expense, yes in substance – Ind AS 102 requires the award to be measured at grant-date fair value, and that cannot be done without an option valuation. Companies not applying Ind AS follow the ICAI Guidance Note on Accounting for Employee Share-based Payments, which likewise requires a fair value measurement. Separately, a perquisite valuation is required on exercise for tax purposes, and that is a different exercise on a different date.

2. Do listed companies need an ESOP valuation if the share price is already known?

Yes. A quoted price gives you the value of the underlying share, which is one of six inputs. It does not give you the fair value of the option, which also depends on the exercise price, expected life, volatility, the risk-free rate and expected dividends. The option’s fair value has to be derived using an option pricing model.

3. What is the difference between graded and cliff vesting?

Cliff vesting means the entire grant vests on a single date. Graded vesting means it vests in instalments across several dates. Under Ind AS 102 a cliff grant is one arrangement requiring one valuation, whereas each instalment of a graded grant is a separate arrangement requiring its own valuation, its own expected life and its own attribution period.

4. Can a graded vesting ESOP be expensed on a straight-line basis?

Not under Ind AS 102. Each tranche must be recognised over its own vesting period, producing an accelerated, front-loaded profile. The straight-line policy election available under US GAAP for service-condition awards has no counterpart in Ind AS 102.

5. Why is a graded grant worth less than an identical cliff grant?

Because most of its options have a shorter expected life, and option value increases with time to exercise. In the illustration above, the graded grant’s total cost is about 14% lower than the cliff grant’s, on identical option numbers, strike price and share price.

6. If the graded grant costs less overall, why is the first year’s expense higher?

Because the early tranches are recognised over very short vesting periods. Tranche 1 is expensed entirely within Year 1, and parts of the later tranches fall into Year 1 as well. A lower total cost and a higher first-year cost are entirely consistent, and both follow from the same tranche structure.

7. How is expected life determined for ESOPs?

Ideally from the entity’s own history of employee exercise behaviour. Where that history is unavailable, which is usual for first-time grants, the midpoint method is widely accepted: expected life equals the midpoint of the earliest and latest possible exercise dates for that tranche, measured from the grant date.

8. Which volatility should an unlisted company use?

The median historical volatility of a set of listed comparable companies, selected on business similarity and size, measured over a window matching the expected life. A broad sector index is the weaker alternative because it diversifies away the company-specific risk the estimate is meant to capture. The peer set and selection basis should be disclosed.

9. When must the ESOP valuation be performed?

As at the grant date. The fair value of an equity-settled award is fixed at grant and is not remeasured afterwards for share price movements. A valuation performed later, using later inputs, does not meet the standard – though the report itself can of course be prepared afterwards, provided it values the award as at the grant date.

10. Can the same valuation report be used for tax purposes?

No. The Ind AS 102 report values the option at the grant date for accounting. The perquisite computation values the share at the date of exercise under Rule 3(8), and for unlisted shares must come from a SEBI-registered Category I Merchant Banker. They are different subjects, different dates and, for unlisted companies, different signatories.

11. What happens if an employee leaves before vesting?

The grant-date fair value per option is unchanged. What changes is the number of options expected to vest, which is re-estimated at each reporting date with a true-up of the cumulative expense. Under graded vesting the reversal is partial, because already-vested tranches are unaffected – so the computation has to run tranche by tranche.

12. How long does an ESOP valuation take?

For a listed company with a clean scheme document and available price data, the analysis is usually short; the time goes into assembling scheme documents, grant details and the employee-wise schedule. For an unlisted company the enterprise valuation has to be completed first, which extends the timeline. The practical constraint is almost always document readiness, not computation.
