India's CSR and the Social Stock Exchange: How to Spend CSR Through Zero Coupon Zero Principal Instruments

The use of “zero coupon zero principal instruments” as a route for corporate social responsibility (CSR) spending has become one of the more closely watched corporate governance developments in India, as the Social Stock Exchange (SSE) framework matures and companies explore new, capital-market-linked ways to discharge their statutory CSR obligations. Under the framework overseen by the Securities and Exchange Board of India (SEBI) and the Ministry of Corporate Affairs (MCA), companies may, in defined circumstances, subscribe to zero coupon zero principal instruments (ZCZP) issued by Not-for-Profit Organisations (NPOs) registered and listed on the SSE.

This article explains who may use the route, how any applicable cap is calculated, what an impact-assessment exemption removes and preserves, and the practical steps boards and CSR committees should take. It is written for boards, CSR committees, in-house counsel, compliance teams, foreign-owned Indian subsidiaries and NPOs weighing an SSE listing.

Note on sources: the specific rule numbers, cap percentages and effective dates described below depend on the notifications in force at the time of reading. Companies should confirm the precise text of the Companies (Corporate Social Responsibility Policy) Rules and Schedule VII of the Companies Act, 2013 as currently notified by the MCA, together with SEBI’s SSE regulations, before acting.

Executive summary: the SSE-linked CSR mechanism and why it matters

The Social Stock Exchange framework, and the amendments to the CSR regime that connect to it, create a capital-market-linked mechanism for CSR. In broad terms, a company subject to Section 135 of the Companies Act, 2013 may, where the CSR Rules and Schedule VII so permit, count subscription to a zero coupon zero principal instrument issued by an SSE-listed NPO as CSR expenditure. The headline features are as follows. First, the instrument must be issued by an NPO registered and listed on the Social Stock Exchange. Second, such spending may be subject to a cap expressed as a percentage of the company’s total CSR expenditure for the financial year, as prescribed by the CSR Rules.

Third, subscribing companies may be relieved of certain impact-assessment requirements for projects funded through the instrument. Fourth, issuers carry defined obligations, including the treatment of unspent amounts on termination of listing. For boards, the change means new policy language, new diligence, and a new line item in the annual action plan. The remainder of this guide breaks each element down with worked examples and checklists, drawing on the primary sources published by the MCA, the Gazette of India and SEBI. Readers should verify the exact figures and rule references against the notifications currently in force.

The new instrument: what is a “zero coupon zero principal instrument”?

A zero coupon zero principal instrument is a security recognised under SEBI’s Social Stock Exchange framework that pays no interest (zero coupon) and returns no principal (zero principal) to the subscriber. In economic terms it is not a debt security in the conventional sense, the subscriber does not expect financial return or repayment. Instead, the amount subscribed is deployed by the issuing NPO to deliver a defined social project. The instrument is the mechanism by which philanthropic capital is raised, tracked and reported through a regulated exchange platform rather than through a private donation.

Only an NPO that is registered and listed on the Social Stock Exchange may issue the instrument. This listing requirement is central: it imports SEBI’s disclosure, reporting and governance standards into the funding pipeline, giving subscribing companies a regulated counterparty and a standardised information set. The project financed by the instrument is time-bound; the issuer runs it for a defined period, and any amount that remains unspent when the listing terminates is dealt with in accordance with the applicable framework. These features distinguish the instrument from an open-ended charitable grant and align it with the project-based, outcome-oriented logic of the SSE.

Comparison with conventional CSR instruments

Traditional CSR routes involve direct implementation by the company, contributions to a registered trust or Section 8 company, or grants to implementing agencies registered as required under the CSR Rules. In each case the company retains substantial control over project selection, design and monitoring, and, for larger projects meeting the prescribed threshold, is often required to conduct an impact assessment. The zero coupon zero principal route differs in three ways. It channels funds through a market-listed vehicle rather than a bilateral arrangement; it substitutes SEBI’s SSE disclosure regime for a degree of company-led verification; and, where the CSR Rules so provide, it may relieve the funded project of the impact-assessment burden.

The trade-off is reduced day-to-day control in exchange for standardised, exchange-supervised reporting. Understanding this trade-off is fundamental to any decision on CSR spending through the new instrument.

Which companies can use this CSR route (eligibility)

Eligibility flows from Section 135 of the Companies Act, 2013. Any company that meets the prescribed net worth, turnover or net profit thresholds, and therefore has a statutory CSR obligation, may, where permitted, elect to discharge part of that obligation by subscribing to a zero coupon zero principal instrument, subject to any prescribed cap and the remaining requirements of the CSR Rules. The framework does not create a new class of obligated companies; it adds a permitted mode of spending for companies already within Section 135.

Companies running multiple CSR projects can integrate the instrument alongside their existing portfolio. The instrument is not a substitute for the company’s broader CSR programme but one channel within it, constrained by any applicable cap. A company that spends across direct projects, trusts and implementing agencies may allocate a slice, up to the prescribed percentage of total CSR spend for the year, to SSE instruments while continuing conventional activity for the balance.

Subsidiaries and group-wide considerations

Foreign-owned Indian subsidiaries that satisfy the Section 135 thresholds are eligible on the same footing as domestic companies. However, they should overlay additional analysis. Where a parent group operates a global CSR or ESG strategy, subscription decisions should be reconciled with group governance policies and reporting frameworks. Transfer-pricing and foreign-exchange considerations may arise where group entities coordinate contributions or where cross-border approvals are involved. Boards of such subsidiaries should confirm that a decision to route CSR through SSE instruments is authorised under both Indian law and parent-level governance, and that the arrangement is documented for group audit purposes.

For companies whose financial year runs from April to March, eligibility should be tested against the projected CSR figure for the year in which the spending is to be counted.

How the cap is calculated: worked examples

Where the CSR Rules limit CSR spending through zero coupon zero principal instruments, the limit is expressed as a percentage of the company’s total CSR expenditure for the financial year. The base for the calculation is the company’s total CSR expenditure for that year, the figure the company is required to spend and account for under Section 135 and the CSR Rules, not merely the amount actually deployed through any single channel. Practically, this means a company first determines its total CSR obligation and spend for the year, then applies the prescribed ceiling to establish the maximum permissible allocation to SSE instruments.

The examples below assume a ceiling of 10% for illustration only; companies must apply the percentage actually prescribed by the CSR Rules in force.

In the mid-sized example, a company with a total CSR expenditure of INR 2 crore may, applying an illustrative 10% ceiling, direct up to INR 20 lakh into zero coupon zero principal instruments, with the remaining INR 1.8 crore delivered through direct projects, trusts or implementing agencies. In the large-company example, a total CSR spend of INR 10 crore permits up to INR 1 crore through the instrument. For the foreign-owned subsidiary with INR 4.5 crore of CSR expenditure, the ceiling is INR 45 lakh.

Several practical points follow. The cap is a ceiling, not a target, companies are free to allocate less, or nothing, to the instrument. The relevant test is the total CSR expenditure for the financial year in question, so companies should measure the subscription against the year in which it is counted as CSR spend. Boards should track subscriptions against the running cap throughout the year to avoid inadvertently exceeding the limit when the final CSR figure is confirmed. Where the projected CSR figure is revised during the year, the permissible headroom for SSE-instrument spending must be recalculated so that the allocation remains within the limit at year-end.

Impact-assessment exemption: what is removed and what remains

One significant feature of routing CSR through zero coupon zero principal instruments is the potential relief from the impact-assessment requirement for projects funded through the instrument, where the CSR Rules so provide. This removes a compliance and cost burden that would otherwise apply to qualifying CSR projects meeting the prescribed spend threshold, and reflects the logic that the SSE listing and SEBI’s disclosure regime already impose independent oversight on the issuer and the funded project. Companies should confirm the precise scope of any such exemption against the current text of the CSR Rules.

Crucially, any exemption is targeted. It removes a specific impact-assessment obligation; it does not switch off the wider CSR compliance framework. The other requirements of the CSR Rules continue to apply to the subscribing company. In substance, this means that a company using the instrument must still discharge its board oversight, monitoring, record-keeping and reporting obligations. The company remains accountable for ensuring that the amount subscribed is genuinely CSR expenditure, that it is recorded correctly, and that it is disclosed in the board report and annual return in the ordinary way.

Practical consequences for procurement, monitoring and verification

Boards should not read any exemption as a licence to disengage. While a formal impact assessment may not be required for the funded project, the CSR committee retains a duty to monitor deployment and to satisfy itself that the subscription serves a legitimate Schedule VII purpose. In practice, monitoring is achieved by relying on the issuer’s SSE reporting: the periodic disclosures, use-of-proceeds statements and compliance reports that an SSE-listed NPO is required to produce. Procurement discipline shifts from designing bespoke impact metrics to selecting a credible, well-governed issuer and then tracking its reported performance.

The exemption therefore changes the nature of the company’s diligence, from downstream verification of outcomes to upstream selection of a regulated, transparent counterparty, rather than eliminating oversight altogether.

Board oversight, CSR committee actions and reporting updates

Using the route requires concrete governance action before a company can subscribe. The board and CSR committee should treat the decision as a policy event, not merely an operational one. The first step is to amend the CSR policy to expressly permit spending through zero coupon zero principal instruments issued by SSE-listed NPOs, and to record any applicable cap as an internal control. The annual action plan should then be updated to identify the intended allocation, the issuer or issuers under consideration, and the monitoring approach.

Practical governance measures include:

• Policy amendment. Update the CSR policy to reference the new mode of spending, any statutory cap and the reliance on SSE disclosures for monitoring.
• Annual action plan. Record the proposed subscription amount and confirm it falls within the permitted headroom for the year.
• Board and committee resolutions. Adopt resolutions approving the policy amendment and the specific subscription, and minute the diligence relied upon.
• Record-keeping. Retain subscription documentation, evidence of fund transfer, and the issuer’s SSE compliance reports.
• Periodic review. Schedule committee review of issuer disclosures and of the running total against any cap.
• Disclosures. Reflect the subscription in the board report CSR disclosures and the annual return.

Annual reporting and statutory filings

The subscription must be captured in the company’s CSR reporting in the same manner as other CSR expenditure. That includes the CSR disclosure appended to the board report and the relevant MCA filings that carry CSR data. Because the instrument is exchange-listed, the company should also retain copies of the issuer’s SEBI-facing compliance reports as part of its own audit trail, so that its reliance on those disclosures is documented. Accurate categorisation matters: the amount routed through the instrument should be identifiable within the total CSR spend so that a reviewer can confirm any applicable cap has been respected.

Suggested board resolution wording

At a high level, a resolution might record that the board, on the recommendation of the CSR committee, approves amendment of the CSR policy to permit CSR spending through zero coupon zero principal instruments issued by NPOs listed on the Social Stock Exchange, up to any statutory limit prescribed by the CSR Rules on total CSR expenditure for the financial year, and approves subscription to a specified instrument having completed diligence on the issuer. This is illustrative only; companies should have resolutions and policy language reviewed by counsel before adoption.

Due diligence checklist for subscribing companies

Because a formal impact-assessment obligation may be removed, the company’s protection lies in the quality of its upfront diligence on the issuer. Subscribing companies, and especially foreign-owned subsidiaries operating under group governance standards, should run a structured review before committing funds. The diligence should cover legal status, listing compliance, project parameters, financial integrity and exit contingencies.

The diligence file should be preserved alongside the board minutes so that the company can demonstrate, if questioned, that it exercised reasonable care in selecting the issuer. For groups, this file also supports parent-level assurance and audit. Robust diligence is the cornerstone of defensible CSR spending through the instrument.

Issuer obligations and lifecycle of funds

The issuing NPO carries its own set of obligations that shape the subscriber’s risk. The issuer runs the funded project for a defined period, giving the instrument a defined lifecycle rather than an indefinite deployment horizon. Where the listing is terminated, the treatment of any unspent amount is governed by the applicable SSE and CSR framework, which is designed to ensure that undeployed philanthropic capital is not stranded but redirected to a recognised purpose. The issuer is also required to submit compliance and disclosure reports in accordance with SEBI’s requirements, which supply the information subscribing companies rely on.

These obligations interlock with the retained requirements of the CSR Rules applicable to the subscribing company. The issuer’s SEBI reporting and the treatment-of-unspent-funds mechanism function as the regulatory backstop that supports any impact-assessment relief. Subscribing companies should confirm, as part of diligence, that the issuer understands and can evidence these lifecycle duties, and should track the unspent-fund position through the issuer’s disclosures during the project term.

Comparison table: SSE instrument route vs traditional CSR routes

Cross-jurisdictional brief: comparable social-impact capital-market routes

India’s SSE sits within a broader international trend of connecting philanthropic and impact capital to regulated market infrastructure. The United Kingdom pioneered social impact bonds, outcome-based instruments in which capital funds social interventions and returns are linked to measured results. Several jurisdictions have developed social bond markets and, in some cases, social stock exchanges designed to channel funds to social enterprises and non-profits through transparent, exchange-supervised mechanisms. The common thread is the use of a regulated platform to standardise disclosure and build investor confidence.

For Indian companies, the comparative experience offers practical lessons rather than direct precedent. International markets show that the credibility of such instruments depends on the quality of the exchange’s disclosure regime, the discipline of outcome measurement, and the governance of issuing organisations. They also illustrate a recurring tension between reduced administrative burden for funders and the need for reliable, independent verification of social outcomes. As Indian companies consider CSR spending through the SSE, the international pattern suggests that early adopters should prioritise issuers with strong governance and transparent reporting, since the reputational value of the route will ultimately rest on demonstrable social results.

Risks, common pitfalls and mitigations

The route carries distinct risks that boards should weigh. The principal legal risk is exceeding any prescribed cap, which would compromise the CSR compliance status of the excess amount. The principal reputational risk is association with an issuer that underperforms or faces delisting. Accounting risk arises from mischaracterising the subscription or failing to identify it clearly within total CSR spend. Compliance risk stems from over-relying on any exemption and neglecting the retained monitoring and reporting duties.

Mitigations follow directly from these risks: maintain a live cap tracker; select issuers with strong governance and clean SSE compliance histories; retain full documentation including the issuer’s SEBI compliance reports; and preserve board minutes evidencing diligence and approval. Contractual protections in the subscription arrangement can reinforce these controls.

Practical contract clauses to require

Where the subscription arrangement permits, subscribing companies should seek clauses addressing use-of-proceeds ring-fencing, periodic reporting access, confirmation of the project duration, notification obligations on any listing change, and confirmation of the issuer’s undertaking regarding the treatment of unspent amounts on delisting. These clauses codify the statutory protections at the transaction level and give the subscriber a documented basis for reliance.

Practical action list for boards, CSR committees and foreign-owned subsidiaries

• Confirm the current rule text, cap percentage and effective date against the notifications in force before acting.
• Test the permitted headroom against the projected total CSR expenditure for the financial year.
• Amend the CSR policy to permit spending through SSE-listed zero coupon zero principal instruments.
• Update the annual action plan to record the intended allocation and monitoring approach.
• Complete structured diligence on any prospective issuer using the checklist above.
• Record board and CSR committee approvals with supporting minutes.
• Update reporting templates so the subscription is identifiable within total CSR spend.
• Retain subscription documents, transfer evidence and the issuer’s SEBI compliance reports.
• For foreign-owned subsidiaries, reconcile the decision with parent governance and consider transfer-pricing and foreign-exchange implications.

Executed in sequence, these steps allow a company to adopt the route with confidence while keeping CSR spending firmly within any statutory limits and the retained obligations of the CSR Rules.

Conclusion

Routing CSR through zero coupon zero principal instruments marks a meaningful shift in how obligated companies can deploy CSR, connecting statutory philanthropy to India’s regulated Social Stock Exchange. The route offers real advantages, a standardised, exchange-supervised channel and potential relief from a separate impact-assessment burden, but it comes with any prescribed cap and a continuing framework of board oversight, monitoring and reporting under the CSR Rules. Boards that adopt the route deliberately, with amended policies, disciplined cap tracking and rigorous issuer diligence, will be well placed to use it lawfully and credibly.
