Going only by numerical threshold could create further ambiguities in determinig control definition in takeover code, they argue Top law firms have expressed concern over the proposed move by the Securities and Exchange Board of India ( Sebi) to introduce a ‘Brightline’ test for determination of ‘control’ in the takeover code for listed companies. While some say the current definition should be retained, others say not giving exit options in situations where control is transferred by means other than acquiring a specified shareholding could go against the objective of the code. In March, Sebi had floated a discussion paper titled Brightline Tests for Acquisition of ‘ Control’ under its Takeover Regulations. In this paper, Sebi had discussed two options. The first was to prescribe a framework of protective rights, which would not amount to control. The second was to set a numerical threshold of 25 per cent and exclude other means such as special rights from open offer requirements
