Mahanagar Telephone Nigam Limited sees a credit rating action

As of September 30, 2026, MTNL reported total principal and interest in default of Rs 4,183 Crores, comprising:

• Principal repayment default: Rs 2,246 Crores
• Interest payment default: Rs 1,937 Crores

Aggregate: Rs 4,183 Crores ^[1]

Instruments classified as in default

The disclosure identifies defaults under:

• Loans and revolving facilities from banks or financial institutions, including facilities such as cash credit. The reported default relates to these bank/FI borrowings, against total outstanding bank loans of Rs 9,732 Crores ^[1].
• Non-convertible debentures (NCDs) and NCRPS: the disclosure records the outstanding amount and default amount as “NA”; it does not quantify or classify these instruments as being in default ^[2].
• Term loans: term loans are not separately identified in the cited disclosure. Accordingly, the Rs 4,183 Crores should be attributed to the disclosed bank/FI loan and revolving-facility category, not specifically to term loans.

For context, MTNL reported total financial indebtedness of Rs 37,553 Crores, including bank loans, the sovereign-guaranteed bond and the DoT-related loan, but this is total indebtedness—not the default amount ^[2].

MTNL’s Rs 4,183 crore default is an overdue portion of its bank-loan exposure, not an additional liability on top of total debt. It comprises Rs 2,246 crore of principal and Rs 1,937 crore of interest, against bank loans outstanding of Rs 9,732 crore as at September 30, 2026.^[1]

Reconciliation

The default therefore represents 43.00% of the disclosed bank-loan balance, but only 11.14% of total financial indebtedness of Rs 37,553 crore. The Rs 37,553 crore figure is broader than bank loans because it includes the SG bonds and DoT-related borrowing.^[2]

The year-end balance-sheet debt of Rs 35,425.3 crore is Rs 2,127.7 crore lower than the September disclosure. That difference should not be treated as a missing default amount: the two figures have different reporting dates and apparently different disclosure perimeters. The September filing also does not provide a line-by-line bridge to the audited balance sheet.

Interest and net-worth impact

The Rs 1,937 crore interest default should not be directly compared with Q4 FY26 finance costs of Rs 738.12 crore, because the former is an as-of-date overdue amount while the latter is a quarterly income-statement charge.^[4] The Rs 3,750 crore DoT borrowing is funding linked to payment of SG-bond interest; it is not itself a Rs 3,750 crore interest expense.^[2]

MTNL’s latest year-end total equity, the accounting measure of net worth, was already negative at Rs 29,959.7 crore.^[5] Consequently:

• The principal default does not automatically create a further net-worth loss; the principal is already part of outstanding debt.
• Interest reduces net worth only to the extent that it is newly accrued, expensed or provided for and is not already reflected in liabilities.
• The filing does not establish how much of the Rs 1,937 crore interest default was already recognized in the balance sheet. Therefore, the incremental impact on net worth cannot be quantified from the disclosure.
• If, purely as a scenario, the entire Rs 1,937 crore had not yet been recognized, net worth would decline by that amount to approximately negative Rs 31,896.7 crore. That is a hypothetical accounting effect, not the reported balance-sheet position.

The evidence supports one documented sovereign-guarantee invocation, but not an invocation by the bank lenders against MTNL’s bank loans. On 12 July 2024, the debenture trustee issued a notice to the Government of India to invoke the guarantee for a sovereign-guaranteed bond interest obligation of Rs 94 crore. This was a bond-payment process involving the trustee and GoI, rather than a bank-lender invocation. ^[6]

For the bank facilities, MTNL reported defaults of Rs 4,183 crore as of 30 September 2026—Rs 2,246 crore of principal and Rs 1,937 crore of interest—against bank-loan outstanding of Rs 9,732 crore. This is a derived default ratio of approximately 42.98% of reported bank-loan outstanding. ^[1] The available disclosure does not report any invocation of a sovereign guarantee or letter of comfort by those banks. The rating-agency account also describes the bank facilities as not guaranteed by the Government of India. ^[6]

Financial-statement classification

The default disclosure has three implications:

• The bank principal and overdue interest remain MTNL financial liabilities until legally settled, waived, refinanced, or otherwise discharged. A default notice by itself does not eliminate the liability or transfer it automatically to the Government of India.
• The defaulted bank principal would ordinarily require current-liability classification if MTNL did not have, at the reporting date, an unconditional right to defer settlement for at least 12 months. Whether any portion can remain non-current depends on the contractual terms and whether a valid restructuring, standstill, waiver, or repayment agreement existed by 30 September 2026.
• The Rs 1,937 crore overdue interest would generally be treated as a presently payable overdue obligation, subject to the company’s actual accounting policy and any subsequent waiver or restructuring.

The sovereign-guaranteed bonds should not be treated as extinguished merely because the trustee issued an invocation notice. MTNL’s reported financial indebtedness still included Rs 24,071 crore of sovereign-guaranteed bonds, alongside Rs 9,732 crore of bank loans and Rs 3,750 crore of DoT-related borrowing for bond interest payments, totalling Rs 37,553 crore. ^[2] A change in MTNL’s liability would require evidence that GoI actually paid or legally assumed the obligation, together with the corresponding accounting treatment.

Bottom line: the disclosed evidence shows a historical invocation for at least one sovereign-guaranteed bond obligation, but no demonstrated invocation of guarantees or letters of comfort by the bank lenders. The 30 September 2026 bank default therefore remains primarily an MTNL liability-classification issue: the overdue amounts should be separately identified as defaulted, and the principal is likely to be current unless MTNL had secured enforceable long-term payment relief before the reporting date. The cited default filing does not itself provide the current/non-current split or confirm any restructuring or waiver.
