What is an event of default on a debt security?

An event of default on a debt security in India is not a judgement call about how badly an issuer is doing. SEBI defines it as a missed payment, recognises it at the first instance of delay, and counts it at the ISIN level rather than across the issuer. This guide covers the definition, why the ISIN rule matters when one offer document produced several lines, and the clock that starts the moment a default happens. It is not investment advice.

How does SEBI define default on a debt security?

By reference to the payment, not to the issuer's condition. Paragraph 1.1 of Chapter X of SEBI's Master Circular for Debenture Trustees, SEBI/HO/DDHS-PoD-1/P/CIR/2025/117 dated August 13, 2025, points to Regulation 51 of the LODR Regulations read with the Explanation to Clause A(11) in Part B of Schedule III. Default there means non-payment of interest or principal amount in full on the pre-agreed date.

The Explanation carries the part people miss. Default "shall be recognized at the first instance of delay in the servicing of any interest or principal on debt". There is no materiality threshold written into the definition and no built-in grace window. A partial payment is not a payment, because the test is payment in full on the pre-agreed date.

That does not mean cure periods do not exist. It means they live somewhere else, in the terms of the issue and the debenture trust deed. Annex VIA of the same master circular lists cure period allowed and extra interest payable under its default covenant category, which is the drafting layer where those consequences get set. The regulatory recognition of default and the contractual consequences of it are two separate questions.

Why is an event of default reckoned at the ISIN level?

Because the issuance structure and the security are not the same thing. Paragraph 1.2 of Chapter X clarifies that the event of default is reckoned at the ISIN level, and gives the reason directly: all terms and conditions of issuance of the security are the same under a single ISIN, even though that ISIN might have been issued under multiple offer documents.

Two situations forced the clarification:

For anyone reading disclosures, this is the practical consequence: an issuer can be in default on one ISIN and current on another, and both statements can be true at the same time. Read a default disclosure against the ISIN it names, not against the issuer as a whole.

What happens in the first three days?

The trustee has to tell the holders. Paragraph 3.3.1 of Chapter X requires the debenture trustee to send a notice to investors within three days of the event of default. SEBI is specific about the delivery method, because the proof matters later:

• Registered post with acknowledgement due, or speed post with acknowledgement due, or courier, or hand delivery with proof of delivery
• And also by email, as text or as an attachment, with a notification including a read receipt
• Proof of dispatch of the notice or email must be maintained

The word "and" is doing work there. Email alone does not discharge the obligation, and neither does post alone. Both channels are required, and the trustee keeps the evidence.

A meeting follows. Under paragraph 3.3.3 the debenture trustee convenes a meeting of holders of listed debt securities within 30 days of the event of default, with one exception written into the proviso: if the default is cured between the date of the notice and the date of the meeting, convening the meeting may be dispensed with. So a cured default can leave a notice trail and no meeting.

Who appoints a director when defaults repeat?

The trustee, once the trigger in the regulations is met. Regulation 15(1)(e) of the SEBI (Debenture Trustees) Regulations, 1993 requires the debenture trustee to appoint a nominee director on the board of the company on two consecutive defaults in payment of interest, or default in creation of security, or default in redemption.

Chapter X paragraph 2 sets out how that lands on the issuer. Regulation 23(6) of the NCS Regulations obliges an issuer that is a company under the Companies Act, 2013 to ensure its Articles of Association require its board to appoint the trustee's nominee. Issuers that are not such companies instead give their trustee an undertaking that a non-executive or independent director, trustee, or member of the governing body will be designated as nominee director, in consultation with the debenture trustee, or with all of them where there are several.

Where an event of default sits in the sequence

A covenant breach and an event of default are different points on the same track. Breach monitoring and the actions available before a missed payment are covered in what happens when a bond covenant is breached. Once a default has been declared, the consent machinery for enforcing security is set out in debenture holder consent for enforcement of security, the restructuring route is in what is an inter-creditor agreement, and the fund that pays for enforcement is covered in what is a Recovery Expense Fund. The full list of trustee obligations is in duties of a debenture trustee.

An event of default on a debt security is a defined, dated, ISIN-level event with a disclosure trail attached to it. Flock reports what issuers and trustees disclose, with the source and the date attached. It is not investment advice.
