FIIS with earlier 10% upfront payment method used to give artificial subscription figures to IPOs.Generally FIIs & HNIs overall subscription would be equal but now in this IPO FIIs overall subscription is 4.2782 while that of HNIs is 46.385.So that is the difference with 100% upfront payment for FIIs.GMP depends on HNI figure,hence expect it to go up.Aster GMP went from 2 to 10 after IPO.
