The SEBI (Issue and Listing of Non-Convertible Securities) Regulations, 2021 principally require, for the ISSUE of listed debt, inter alia:

Explanation: The NCS Regulations, 2021 govern the public issuance and listing of non-convertible securities such as debentures and bonds, prescribing ELIGIBILITY, CREDIT-RATING requirements (investment-grade ratings), prospectus/disclosure obligations, allotment and listing timelines, and continuing obligations. An investment-grade credit rating and transparent disclosures are central. Equity issues are separately governed by ICDR regulations; SEBI does not register every bondholder; and securities are listed, not physically transferred to the exchange. NCS therefore streamlines the corporate-debt market, relevant for IndianOil's bond issuances.
