Zero coupon bond defined by issuer eligibility, no interim payments, and government notification requirement.

Zero coupon bond is defined by three operative criteria: specified eligible issuers, absence of any payment or benefit from the issuer before maturity or redemption, and inclusion by Central Government notification. Eligible issuers include infrastructure capital companies, infrastructure capital funds, infrastructure debt funds, public sector companies and scheduled banks. Explanations clarify that "scheduled bank" and "infrastructure debt fund" take their meanings from the Act's specified cross-references and government notifications.
