Key Takeaways
- Ind AS 102 requires companies to measure ESOPs at fair value on the grant date, not at intrinsic value or face value.
- The Black-Scholes model is the most widely used option pricing method in India for ESOP valuation due to its simplicity and auditability.
- Binomial and Monte Carlo models are better suited for ESOPs with complex features like performance conditions, early exercise provisions, or graded vesting.
- Every option pricing model under Ind AS 102 must account for six mandatory inputs: stock price, exercise price, expected life, volatility, risk-free rate, and dividend yield.
- Volatility estimation for unlisted companies is one of the most challenging inputs, typically derived from peer company data or sector benchmarks.
- Equity-settled and cash-settled ESOPs follow different valuation frequencies: equity-settled options are valued once at grant, while cash-settled options are revalued at every reporting date.
- Common compliance failures include using intrinsic value instead of fair value, relying on stale assumptions, and missing mandatory disclosures in financial statements.
Your company has just approved its first ESOP scheme. The board resolution is signed, the vesting schedule is locked, and employees are excited. Now comes the part that trips up most finance teams: the valuation. Under Ind AS 102, every ESOP grant must be valued at fair value using a recognised option pricing model, and the resulting expense must flow through your profit and loss statement. Getting this wrong does not just create audit headaches; it can misstate your reported earnings and erode investor confidence.
At Equirium Analytics, we see this challenge regularly across startups and established companies alike. This guide breaks down the methods, inputs, and compliance requirements so you can approach ESOP valuation with clarity.
What Does Ind AS 102 Require for ESOP Valuation ?
Ind AS 102 (Share-Based Payments) mandates that companies recognise the cost of employee stock options as a compensation expense in the profit and loss statement. This expense is measured at the fair value of the option on the grant date and is spread over the vesting period.
The standard applies to both listed and unlisted companies that follow Indian Accounting Standards. It covers equity-settled transactions (where employees receive shares), cash-settled transactions (where employees receive cash based on share price movements), and transactions with cash alternatives.
The core requirement is straightforward: you cannot simply record the difference between the exercise price and the current share price. Instead, you must use an option pricing model that captures the time value of the option, expected volatility, and other market factors. The grant date is the measurement date for equity-settled ESOPs, meaning the fair value is locked in at the point both parties agree to the arrangement.
For companies that require shareholder approval for their ESOP scheme, the grant date is the date that approval is obtained, not the date the board first proposed the scheme. This distinction matters because the fair value inputs (especially share price and volatility) can change significantly between these two dates.
Why Fair Value, Not Intrinsic Value, Is the Standard Under Ind AS 102 ?
Intrinsic value is simply the difference between the current share price and the exercise price. If an option has an exercise price of ₹100 and the current share price is ₹150, the intrinsic value is ₹50. If the share price is below ₹100, the intrinsic value is zero.
The problem with intrinsic value is that it ignores the time value of the option. An employee holding an option with a five-year life has a significant economic benefit even when the current share price is below the exercise price. The option gives them the right to buy shares at a fixed price for five years, and markets can move substantially in that period. Intrinsic value captures none of this.
Ind AS 102 explicitly requires fair value measurement because it reflects the true economic cost of the ESOP to the company. Fair value accounts for time to expiry, expected volatility, dividends, and the risk-free rate, giving a complete picture of what the option is worth on the open market.
Consider this scenario: a startup grants 10,000 ESOPs with an exercise price equal to the current share price (at-the-money options). Under the intrinsic value method, the recorded expense would be zero because there is no immediate spread. Under fair value using Black-Scholes, the same options might be valued at ₹45 per option, resulting in a total ESOP expense of ₹4,50,000 spread over the vesting period. The difference is material, and understating it can lead to audit qualifications and questions from investors about the reliability of your reported compensation costs.
How the Black-Scholes Model Works for ESOP Valuation
The Black-Scholes Option Pricing Model is the most commonly used method for ESOP valuation under Ind AS 102 in India. Both listed and unlisted companies rely on it because of its transparency and wide acceptance by auditors and regulators.
The model calculates the fair value of a stock option by considering six inputs: the current stock price, the exercise price, the expected life of the option, the expected volatility, the risk-free interest rate, and the expected dividend yield. It produces a single fair value per option, which is then multiplied by the number of options expected to vest to arrive at the total ESOP expense.
When Black-Scholes works well:
It is ideal for ESOPs with straightforward vesting conditions (time-based, cliff or graded), European-style exercise (exercisable only at maturity), and no complex performance triggers. For the majority of Indian startups and mid-sized companies with standard ESOP plans, Black-Scholes provides an efficient, cost-effective, and auditor-accepted valuation.
Where it falls short:
Black-Scholes assumes that the option can only be exercised at maturity. In practice, most ESOPs allow early exercise after vesting. It also cannot directly handle performance-based vesting conditions tied to total shareholder return (TSR) or revenue milestones. For these situations, a Binomial or Monte Carlo approach is more appropriate.

Black-Scholes vs. Binomial vs. Monte Carlo: Which Model Should You Use ?
Choosing the right option pricing model depends on your ESOP plan design, data availability, and the complexity of vesting conditions. Here is a side-by-side comparison:
| Feature | Black-Scholes | Binomial (Lattice) | Monte Carlo Simulation |
|---|---|---|---|
| Complexity | Low | Moderate | High |
| Best used for | Standard time-based ESOPs, European-style exercise | ESOPs with early exercise provisions, graded vesting | Complex performance conditions, TSR-linked vesting |
| Exercise assumption | Exercise at maturity only | Models early exercise at multiple nodes | Simulates thousands of price paths and exercise scenarios |
| Handles performance conditions? | No (only market conditions with adjustments) | Partially (can model some behavioural factors) | Yes, including non-market conditions like revenue targets |
| Data requirements | Six standard inputs | Six inputs + early exercise assumptions | Six inputs + correlation data, performance probability |
| Cost and time | Lowest | Moderate | Highest |
| Auditor acceptance in India | Widely accepted, most common | Accepted, less common | Accepted, used mainly by large or listed companies |
| Accuracy for simple plans | High | High (marginal improvement over BS) | Unnecessarily complex |
| Accuracy for complex plans | Limited | Good | Best |
Practical guidance: For most Indian startups and private companies with standard time-based ESOPs, Black-Scholes is sufficient and cost-effective. Move to a Binomial model if your plan includes American-style early exercise or graded vesting with distinct tranches. Use Monte Carlo only when your ESOP has TSR-linked performance conditions or other complex, path-dependent features that the other two models cannot capture.
What Are the Six Mandatory Inputs for Option Pricing Under Ind AS 102 ?
Ind AS 102 requires that every option pricing model, regardless of which one you choose, must account for at least these six factors:
1. Current stock price (spot price):
For listed companies, this is the closing market price on the trading day before the grant date. For unlisted companies, the stock price must be determined through an independent equity or business valuation, typically using a DCF, NAV, or comparable company approach. This underlying share valuation is a separate exercise from the option valuation itself.
2. Exercise price (strike price):
The price at which employees can buy shares when they exercise the option. This is defined in the ESOP scheme document. At-the-money options (exercise price equals current share price) are common, but some plans offer discounted or premium exercise prices.
3. Expected life of the option:
This is not the maximum contractual term. It is the expected average time employees will hold the option before exercising.
4. Expected volatility:
This measures how much the stock price is expected to fluctuate over the option’s life. For listed companies, historical share price volatility over a period matching the expected life is used. For unlisted companies, this input requires peer company analysis or sector benchmarks (covered in the next section).
5. Risk-free interest rate:
The yield on Indian government securities (such as government bonds or treasury bills) with a maturity matching the expected life of the option. If the expected life is four years, use the yield on a four-year government bond.
6. Expected dividend yield:
The expected annual dividend as a percentage of the share price. For companies that do not pay dividends (common among startups), this input is zero. For dividend-paying companies, use the expected future dividend yield, not just the historical yield.
These six inputs feed directly into the Black-Scholes formula, the Binomial lattice, or the Monte Carlo simulation. Getting them right is critical, because even a small change in volatility or expected life can shift the fair value of each option significantly.
Equity-Settled vs. Cash-Settled ESOPs: Does the Valuation Approach Differ ?
The option pricing methodology itself (Black-Scholes, Binomial, or Monte Carlo) does not change between equity-settled and cash-settled plans. The same models and the same six inputs apply to both types. However, Ind AS 102 treats them very differently for accounting and valuation frequency purposes.
Equity-settled ESOPs (the most common type in India) are valued once at the grant date. The fair value is locked in on that date and is not revised even if the share price changes dramatically afterwards. The total expense is recognised over the vesting period based on the number of options expected to vest, with adjustments only for changes in forfeiture estimates.
Cash-settled share-based payments (such as Stock Appreciation Rights or phantom stock) create a liability for the company. Under Ind AS 102, the fair value of cash-settled plans must be remeasured at every reporting date until settlement. This means the company must rerun the option pricing model at each balance sheet date, updating the inputs for current market conditions, and any change in fair value flows through the profit and loss statement.
This distinction has a direct impact on ESOP expense volatility in your financial statements. Cash-settled plans can create significant quarter-to-quarter swings in reported compensation costs, while equity-settled plans produce a predictable, straight-line expense pattern.
How Do You Estimate Volatility for an Unlisted Company ?
Volatility is often the most challenging input for unlisted companies. Since there is no public share price history, you cannot calculate historical volatility directly. Ind AS 102 acknowledges this and permits companies to use reasonable estimation approaches.
Peer company approach: Identify 4–6 listed companies in the same industry and of comparable size. Calculate their historical share price volatility over a period matching the expected option life. Use the median or average of this peer set as the volatility estimate. Document the rationale for peer selection, as auditors will review this.
Sector benchmark approach: Where direct peers are difficult to identify (common for niche or early-stage businesses), use published sector-level volatility data from financial databases or industry reports. This is a less precise but acceptable fallback.
Blended approach: Some valuers use a combination of peer volatility and qualitative adjustments for company-specific risk factors (stage of business, revenue concentration, funding status). Any adjustments should be documented and defensible.
Consistency matters. Once you select a volatility estimation method, apply it consistently across reporting periods. Changing the method without justification raises auditor and investor concerns.

Common Mistakes Companies Make in ESOP Valuation Under Ind AS 102
Even companies with experienced finance teams make avoidable errors in ESOP valuation. Here are the most frequent ones:
Using intrinsic value instead of fair value.
This is the single most common compliance failure. Some companies still record ESOP expense based on the spread between exercise price and share price at grant date. For at-the-money options, this produces zero expense, which materially understates compensation costs. Auditors will flag this as a departure from Ind AS 102.
Relying on stale valuation inputs.
Companies that granted ESOPs before a funding round but did not update their underlying share valuation are working with outdated stock price inputs. While the fair value of equity-settled options is locked at grant, the stock price input must reflect the fair value as of the grant date, not an older valuation.
Ignoring forfeiture estimates.
Ind AS 102 requires companies to estimate the number of options expected to vest, considering expected employee turnover. Many startups assume 100% vesting with no forfeitures, which overstates the ESOP expense. At each reporting date, companies should revise the forfeiture estimate and adjust the cumulative expense accordingly.
Not performing sensitivity analysis.
Auditors expect to see how the fair value changes when key inputs (especially volatility and expected life) are varied within a reasonable range. Omitting sensitivity analysis weakens the credibility of the valuation report and invites audit queries.
Missing mandatory disclosures.
Ind AS 102 requires detailed disclosures in the financial statements, including the nature of the ESOP scheme, the valuation model used, key assumptions (volatility, expected life, risk-free rate, dividend yield), the number of options granted, exercised, forfeited, and outstanding, and the weighted average exercise price. Incomplete disclosures are a common audit qualification trigger.
Not engaging an independent valuer.
While Ind AS 102 does not mandate an independent valuation, auditors and investors strongly prefer it. Self-assessed ESOP valuations face greater scrutiny and are more likely to be challenged during audit.
Frequently Asked Questions
Is ESOP valuation under Ind AS 102 mandatory for all companies ?
Ind AS 102 applies to all companies that follow Indian Accounting Standards. This includes listed companies, unlisted companies with a net worth exceeding ₹500 crore, and their subsidiaries. Companies following older Indian GAAP may refer to the ICAI Guidance Note on share-based payments, which follows similar principles.
What is the difference between grant date fair value and exercise date FMV ?
Grant date fair value is the value of the option (not the share) calculated using an option pricing model on the date the ESOP is granted. Exercise date FMV is the fair market value of the underlying share on the date the employee exercises the option. The first is used for Ind AS 102 accounting; the second is used for computing perquisite tax under the Income Tax Act.
Can a company use the Binomial model instead of Black-Scholes ?
Yes. Ind AS 102 does not mandate any specific option pricing model. Companies are free to use Black-Scholes, Binomial, Monte Carlo, or any other model that considers at least the six mandatory factors. The choice depends on the complexity of the ESOP plan design.
How often should ESOP valuation be updated ?
For equity-settled ESOPs, the fair value is measured once at the grant date and is not updated. However, the estimate of options expected to vest (forfeiture rate) must be revised at each reporting date. For cash-settled plans, the fair value is remeasured at every balance sheet date.
Who can perform an ESOP valuation under Ind AS 102 ?
The standard does not restrict who performs the valuation. However, best practice is to engage an independent valuer or a firm with expertise in option pricing models. For the underlying share valuation (needed as an input for unlisted companies), a Registered Valuer (IBBI) or a SEBI-registered Merchant Banker is typically required.
What happens if the ESOP scheme is modified after the grant date ?
If the modification increases the fair value of the options (for example, reducing the exercise price), the incremental fair value is recognised as additional expense over the remaining vesting period. If the modification decreases the fair value, the company continues to recognise the original, higher expense. The company cannot reverse previously recognised ESOP costs due to a downward modification.
How does graded vesting affect ESOP expense recognition ?
Under graded vesting, different tranches of options vest at different dates. Ind AS 102 and the ICAI Guidance Note require each tranche to be treated as a separate grant with its own fair value measurement and expense recognition period. This front-loads the expense compared to straight-line recognition over the full vesting period.
What documents are needed for an ESOP valuation report ?
Key documents include the ESOP scheme document, board and shareholder resolutions, grant letters with vesting schedules, the latest audited financial statements, shareholding pattern, cap table, exercise price details, and projected financials if a DCF-based share valuation is required for unlisted companies.
Does Ind AS 102 apply to SARs and phantom stock plans ?
Yes. Stock Appreciation Rights (SARs) and phantom stock are cash-settled share-based payments under Ind AS 102. They follow the same valuation models but require fair value remeasurement at every reporting date, unlike equity-settled ESOPs.
Can the ESOP expense be reversed if employees leave before vesting ?
Yes. If employees forfeit unvested options (by leaving the company before the vesting date), the company reverses the previously recognised expense for those specific options. This adjustment is made in the period the forfeiture occurs by revising the estimated number of options expected to vest.
