Beleaguered UTI chairman, P S Subramanyam has put in his papers. The move is the fallout of the deteriorating health of UTI's flagship, which has over 2 crore investors. UTI suspended the transaction in US-64 units on July 2 for six months, fearing a run on the fund due to a poor dividend. The suspension decision has come under a flak from all quarters with the BSE Sensex plunging by 114 points on Tuesday. US-64 is the largest fund of the Indian fund industry with a unit capital of over Rs 12,000 crore.
