This would, however, trigger an open offer to minority shareholders unless the Securities and Exchange Board of India (Sebi) grants an exemption. The need for an open offer can be obviated through a merger or an amalgamation, instead of takeover. The other option is that the government sell less than 25 per cent equity, in which case ONGC will not get management control.
Under the Takeover Code prescribed by Sebi, if an entity acquires more than a 25 per cent stake or takes over the management of a listed company, it has to make an open offer on equal terms. The public holding in the company being taken over should, however, not fall below 25 per cent, a requirement for listing.
