Private-company minority discounts: 25 percent or 35 percent — and how to defend whichever you pick

Whenever we value a minority interest in a private Indian company — for a buyout, an estate-planning transfer, a divorce settlement, a Section 56(2)(x) compliance, or an NCLT minority oppression case — the discount conversation is the conversation. The starting point (the controlling-marketable enterprise value) is usually not in serious dispute. The discount applied to translate that into the minority-illiquid value is.

We work through the two discounts that apply, the empirical bases for the magnitudes, and the documentation that distinguishes a defensible report from one that gets dismantled.

The two discounts and what they measure

Discount for lack of control (DLOC)

A controlling shareholder can direct the company's strategy, dividend policy, capital allocation, and exit. A minority shareholder cannot. The minority position is worth less than its proportional share of enterprise value because the minority cannot force the company to monetize value, distribute cash, or pursue an exit.

Empirical magnitudes. Studies of acquisition premia (the price paid for control over the unaffected trading price of public companies) suggest control premiums of 25-40 percent. The inverse — the discount for lack of control — is in the range of 15-30 percent.

India-specific data. The Khaitan & Co valuation studies and the Indian-specific working of the Stout DLOC database suggest DLOC for Indian private companies typically sits in the 20-25 percent range, with adjustments for the specific minority rights of the position (board seats, veto rights, information rights, tag-along).

Discount for lack of marketability (DLOM)

A controlling shareholder of a public company can sell quickly at a known price. A minority shareholder of a private company cannot. Finding a buyer takes time, the price is uncertain, and the transaction costs are high. The position is worth less than its theoretical fair value because it cannot be converted to cash quickly.

Empirical magnitudes. Restricted-stock studies (sales of restricted stock that cannot be freely traded for a defined period) suggest DLOM of 25-35 percent. Pre-IPO studies (sales of private company stock in periods leading up to IPOs) suggest DLOM of 30-50 percent. The Stout DLOM study aggregates these.

India-specific data. Indian unlisted-stock secondary transaction data is thin, and most empirical DLOM evidence is from the US. The Indian DLOM bands used in practice — typically 25-40 percent — are anchored to the US empirical studies with adjustments for the more limited Indian secondary market for private-company shares.

The combined discount

DLOC and DLOM are applied sequentially, not added. The combined effect is approximately:

Combined discount = 1 - (1 - DLOC) × (1 - DLOM)

For DLOC of 20 percent and DLOM of 30 percent: combined = 1 - 0.8 × 0.7 = 1 - 0.56 = 44 percent.

For DLOC of 25 percent and DLOM of 35 percent: combined = 1 - 0.75 × 0.65 = 1 - 0.4875 = 51 percent.

The realistic range for a minority interest in a private Indian company is a combined discount of 35-55 percent from the controlling-marketable enterprise value. A minority position with strong contractual rights (tag-along, drag-along participation, anti-dilution, information rights) sits at the low end. A minority position with no contractual rights sits at the high end.

How to defend the chosen discount

The number is not picked from a range. It is defended with specific reference to the minority position's characteristics. The defense has five elements.

Element one: comparable transactions

The most defensible support for the discount is recent comparable transactions in the same company or in similar Indian private companies. If a previous minority sale in the same company implied a discount of 38 percent from the implied enterprise value at the time, that data point anchors the current valuation.

Sources: NCLT minority oppression case files (where applicable), Companies Act filings showing prior preferential allotments and the implied valuation, and the company's own cap table history.

Element two: empirical studies

Reference to the underlying empirical literature. The Stout restricted-stock study, the Mergerstat acquisition premium study, the pre-IPO studies (Emory, Robert Reilly), and Indian-specific working papers from the ICAI Valuation Standards Board.

The report cites the studies, summarizes the empirical ranges, and explains how the studies inform the chosen discount.

Element three: position characteristics

Specific to the minority position being valued.

Size of holding: a 10 percent stake is harder to sell than a 49 percent stake. The DLOM is higher for smaller holdings.

Contractual rights: tag-along, drag-along, information rights, board representation. Stronger rights reduce DLOC and may reduce DLOM.

Transfer restrictions: rights of first refusal, lock-ups, consent requirements. More restrictions increase DLOM.

Distribution policy of the company: a company with a regular dividend has lower DLOM than one with no dividend policy.

Expected liquidity event: a company with a credible 18-24 month exit pipeline has lower DLOM than one with no exit path.

Element four: quantitative DLOM model

For DLOM specifically, a quantitative model is much more defensible than asserting a number from a study. The standard models:

Finnerty model. Treats DLOM as the value of a put option on the underlying stock. Inputs: holding period, volatility of comparable listed stocks, risk-free rate. The output is a DLOM percentage that reflects the optionality lost by being unable to sell during the restricted period.

Longstaff model. Similar approach using an Asian put option formulation.

Chaffe model. A simpler put-option model.

The quantitative model produces a number that is anchored to observable inputs (volatility data is available for listed Indian stocks; holding periods can be estimated from the company's exit pipeline). The output is much harder to attack than a sentence saying '30 percent discount for lack of marketability applied based on industry practice.'

Element five: cross-check against the alternative method

For minority interests, the income approach DCF can be modified to incorporate the minority discount directly. Instead of valuing the enterprise and then applying a discount, the DCF can be built on the basis of the cash flows the minority shareholder can actually expect to receive (dividends plus eventual exit), discounted at the minority's required rate of return.

The two methods should produce reasonably consistent answers. When they diverge by more than 25 percent, the divergence is investigated and explained.

When the discount is over-applied

Indian tax authorities, particularly in Section 56(2)(x) cases, sometimes challenge minority discounts as being excessive. The argument: the discount is being used as a tool to undervalue the transaction.

The defense. Document each component. Show the empirical basis. Show the Finnerty or Longstaff calculation for DLOM. Show the position-specific analysis for DLOC. A discount with this kind of documentation is hard to dismiss.

What does not work: a single sentence in the valuation report saying 'a combined discount of 50 percent for lack of control and lack of marketability has been applied.' Assessing officers reject this kind of asserted-without-support discount.

NCLT minority oppression cases

When a minority shareholder petitions the NCLT under Sections 241 and 242 of the Companies Act 2013 for oppression and mismanagement, the relief often includes a fair-value buyout of the petitioner's shares by the majority. The valuation question becomes: what is fair value to the minority?

The NCLT's approach. Indian tribunal decisions have varied. Some have applied no minority discount (the petitioner is being forced out, and applying a discount would compound the unfairness). Others have applied a limited discount (recognizing that the minority position would have been worth less in a willing-buyer, willing-seller transaction). The case law is unsettled.

From a valuer's perspective, the report should provide both numbers: the enterprise value, and the discounted minority value. Let the tribunal decide which is appropriate for the relief being granted.

What founders and minority shareholders should know

Two things.

First, a minority position is genuinely worth less than its proportional share of enterprise value. This is not a tax-planning fiction; it is economic reality. A minority shareholder who insists on receiving full pro-rata enterprise value on a buyout is asking for value that the market does not assign.

Second, the magnitude of the discount is contestable. The difference between a 35 percent combined discount and a 55 percent combined discount can be Rs. 5-50 crore on a meaningfully-sized minority position. The negotiation lives in the defense of each input — the contractual rights, the position size, the empirical references — not in the final percentage. The party with the better-documented analysis wins the discount argument almost every time.
