The NCDs had a coupon rate of 9.8 per cent and Axis Trustee Services was the trustee, it added.
When contacted, a JSPL spokesperson said: "The non payment of interest on the NCDs has been disclosed as per regulatory norms. The said non-payment is due to short-term cash flow mismatches and will be paid in due course."
The firm, in the last few months, has divested some of its assets to pare debt. JSPL has a net debt of around Rs 46,000 crore.
