So, corporates wanting to tap the capital market in India cannot advertise their issue except in the form of standard-format "tombstone" ads giving the date of opening, closing, risk factors and highlights, as soon as they get the SEBI acknowledgement card, the go-ahead for the issue. Corporates, once they received the card, had traditionally bombarded potential "Companies thus cannot effectively time their corporate campaign and may end up blowing money on such campaigns weeks before the issue opens and yet not have the desired results. Public memory is short," says A.P. Verma of Pressman Advertising.
