Residual put option
Also written Residual put
A put option that promoters agree to only as a fallback: the AIF cannot exercise it unless the company fails to list within an agreed time or the AIF cannot use the other exit routes.
In plain language
An AIF investing in an unlisted company needs a way out. The best way is an IPO; failing that, a sale to another fund or a strategic buyer.
A put option is the contractual backstop: the right, but not the obligation, to sell the shares back — to the company or to the promoters — at a price agreed in advance.
Promoters do not like open-ended puts. A buyback can drain the company's cash or the promoters' personal wealth. So they often insist the put be residual: it sits dormant and becomes exercisable only if the company does not go public within an agreed time frame, or the AIF could not use the other exit routes. It is the last door, not the first.
How it works
The exit menu (Chapter 12, section 12.4.3), in the workbook's order of preference:
| Exit | Workbook's view |
|---|---|
| Offer for sale in an IPO | Most preferred; historically the best returns |
| Secondary sale (trade sale) to another AIF or PE fund | When an IPO is not feasible and the horizon is over |
| Strategic sale (M&A) to a corporate buyer | Usually the second most preferred after the IPO; can bring a strategic premium |
| Corporate / promoter buyback through a put option | Not feasible in every case; usually a last resort in a going-concern context |
| Corporate liquidation | Least preferred, worst case; salvage value only |
AIF investment horizons in portfolio companies range from 3 to 7 years or slightly more.
The put option. A buyback happens when the AIF exercises a put on its shares. A put option is a contractual right under the investment agreement: the buyer of a security has the right but not the obligation to sell it back to the seller on the agreed terms. The buyback may be by the company or the promoters, depending on whom the put is exercisable on.
Why it is hard to use.
- Company buyback works better for unlisted companies; listed companies face many more regulatory hurdles, and even unlisted companies must comply with the law.
- Promoter buyback needs large personal or affiliate resources; in many AIF-backed companies promoters are not resourceful enough to honour it.
- AIFs stipulate a stiff put price to compensate for losing an IPO exit. The price is usually set by a formula in the definitive agreements to avoid ambiguity, and in large cases guarantees a certain return or IRR.
The residual condition. For these reasons promoters may stipulate that the put shall be a residual option, not exercisable unless the company does not go public within an agreed time frame or the AIF could not avail of the other exit mechanisms.
The formula
Put price (IRR-based formula) = Investment x (1 + agreed IRR)^years held
(One common form of the "formula in the definitive agreements"; the actual formula is whatever the parties agree.)
A worked example
Vistaar Capital Fund (illustrative throughout), a Category II AIF, invests Rs 25 crore in Rohini Textiles Pvt Ltd in April 2020 for a minority stake.
The clause. The promoters grant a put option on themselves, with a price formula guaranteeing a 15% IRR, but only as a residual put: exercisable if Rohini has not listed by 31 March 2026 and Vistaar has been unable to exit through a secondary or strategic sale.
What happens. Rohini files for an IPO in 2025 but withdraws it. Vistaar runs a sale process; two PE funds bid below cost and no strategic buyer emerges. In April 2026 — six years after investment — both conditions are met and the put becomes exercisable.
| Line | Figure |
|---|---|
| Investment | Rs 25 crore |
| Years held | 6 |
| (1.15)^6 | 2.3131 |
| Put price | 25 × 2.3131 = Rs 57.83 crore |
The workbook's problem, in numbers. The promoters must find Rs 57.83 crore personally or through affiliates. If they cannot, the put is a claim against people who cannot pay — which is why the workbook calls the buyback route a last resort, and why a residual put is worth less than its formula suggests.
Had the clause not been residual, Vistaar could have exercised in 2023 regardless of the IPO plans — exactly what the promoters negotiated to prevent.
Why NISM asks about it
Chapter 12 (Fund Monitoring, Reporting and Exit), section 12.4.3 on commercial exit from investee companies sets out the exit routes, the put option (with its footnote definition), buyback difficulties, formula pricing and the residual put. Expect an ordering question on exit preference (IPO first, strategic sale second, liquidation last) and a question on the conditions under which a residual put becomes exercisable.
Common exam traps
- A residual put is not exercisable at will. It waits for a failed IPO within the agreed time frame, or for the other exit routes to be unavailable.
- A put is the holder's right to sell, not an obligation.
- The buyback may be by the company or the promoters — whoever the put is exercisable on.
- Exit preference: IPO first; strategic sale usually second; buyback a last resort; liquidation least preferred.
- Put prices are set by formula in the definitive agreements and are often stiff, sometimes guaranteeing a return or IRR.
- A guaranteed put price is only as good as the promoters' resources.
