Overseas Direct Investment classification clarified; ODI status persists even if shareholding or control later falls below the threshold. These rules define the core terms governing overseas investments under the Act: ODI (covering unlisted equity, formation subscriptions, substantial stakes in listed foreign entities, and investments with control, with continued ODI treatment despite later reductions in shareholding or control), OPI (investments in foreign securities other than ODI, with OPI status preserved after delisting until further investment), and OI (comprising financial commitment and OPI). The rules also define control, financial commitment, equity capital, net worth and entity categories, and provide sectoral and institutional cross-references.
