Floor price for delisting must equal the highest of specified valuation metrics under SEBI delisting rules. The floor price for delisting must be no less than the highest of specified metrics: the acquirer's 52 week VWAP for acquisitions, the highest acquisition price in the preceding 26 weeks, an adjusted consolidated book value determined by an independent registered valuer (not applicable to PSUs), the 60 day VWAP on the exchange with maximum trading volume for frequently traded shares, or a valuer determined price using customary valuation parameters for infrequently traded shares; the regulation also prescribes the method and components for adjusted book value and sets the reference date rules for computation.
