MTNL said that all bonds issued by MTNL are Sovereign Guaranteed Bonds by the centre.

"In case of any default made by MTNL in payment of Principal and Interest on the Bonds issued by it, then the Sovereign Guarantee will be invoked by the Debenture Trustee and the Government of India is obliged to make the payment to MTNL for the same," the filing said.
