Demerger Structures explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
The session's caution is that these are not interchangeable — one needs no valuation, one rests on an untested reading, and one has no binding precedent at all.
Demerger structures, pattern one: the mirror-image split
The first and most common is the mirror-image split, illustrated by Vedanta, in which the demerged undertaking is transferred to a resulting company that is issued fresh shares to the demerged company's existing shareholders in the same proportion as their existing holding.
Its distinguishing feature: it operates without requiring an independent valuation exercise, since a one-to-one mirror split, by construction, does not shift relative value between shareholders.
That is a substantial practical advantage. Valuation is described elsewhere in these sessions as the central battleground on which most modern restructurings are contested — and a mirror split removes it from the transaction entirely.
Demerger structures, pattern two: the retained stake
The second is the retained-stake structure used in the ITC – ITC Hotels demerger, in which the demerged company itself continues to hold a stake in the resulting company (40 per cent in ITC's case) while the balance (60 per cent) is issued afresh to ITC's own shareholders.
At first sight the structure seems to fail the proportionality condition. Shareholders receive shares representing only 60 per cent of the resulting company, not 100 per cent, and the demerged company keeps the rest.
The session's analysis turns on the precise statutory language: the statute requires that shareholders holding not less than three-fourths in value of the shares of the demerged company become shareholders of the resulting company, a condition the ITC structure satisfies.
The test is about which shareholders become shareholders of the resulting company, measured by value of their holding in the demerged company — not about what percentage of the resulting company they collectively receive. Every ITC shareholder became a shareholder of ITC Hotels, so the three-fourths test is comfortably met.
And the second limb: the law nowhere requires that the demerged company's own retained shareholding in the resulting entity be cancelled.
The session is careful not to overstate this. It was careful to flag this as a view that would need to be tested against the specific facts of any transaction rather than treated as settled law. A structure that a large listed group has adopted is not thereby a precedent for a different set of facts.
Demerger structures, pattern three: into a wholly owned subsidiary
The third, more technical structure arises where an undertaking is demerged from a parent to its own wholly-owned subsidiary. Because the resulting company in such a case is already wholly owned by the demerged company, no fresh shares need be issued to third-party shareholders at all, and the session noted that the statutory definition of a resulting company can, on one reading, still be satisfied in this scenario, making this a third, more contested route to structuring a demerger for which no binding precedent yet exists, though it has reportedly been used in practice.
| Pattern | Shares issued to | Status |
|---|---|---|
| Mirror-image split | Existing shareholders, same proportion | Most common; no independent valuation required |
| Retained stake | Existing shareholders for part; demerged company retains the balance | Should in principle qualify, but needs testing on the facts |
| Into a wholly owned subsidiary | No fresh shares to third-party shareholders at all | More contested; no binding precedent yet exists |
Stamp duty falls on two triggers
Stamp duty in any merger or demerger falls due on two distinct triggers: firstly, on the value of shares issued as consideration by the resulting company and secondly, on the conveyance of any immovable property that changes hands, with the applicable rate and any cap governed by the specific state in which the property is situated, so that a single restructuring touching assets in multiple states can attract stamp duty in each of them.
The practical advice: since stamp-duty adjudication typically follows completion of the NCLT process and adjudicating authorities routinely call for supporting valuation, whether based on net worth or fair value, build the price-discovery and stamp-duty analysis into the transaction timeline from the outset, including for unlisted-company demergers where no market price exists to anchor the valuation.
Note the sequencing problem this creates. Adjudication comes after the scheme is complete, so a company that has not modelled the duty discovers the figure when it can no longer restructure to reduce it.
The open question on cost of acquisition
The session flagged as an open and commercially significant question how the cost basis of shares held in a demerged listed company should be apportioned between the demerged company and the resulting company following a demerger, particularly where the original shares were acquired well before the demerger.
Every shareholder of a demerged listed company faces this, and the answer determines their capital gain whenever either holding is eventually sold.
Common mistakes
- Treating the three demerger structures as interchangeable patterns.
- Reading the three-fourths test as a percentage of the resulting company.
- Adopting the wholly-owned-subsidiary structure as though it were settled.
- Leaving stamp duty analysis until adjudication follows completion.
