Amidst rising worries about the plunging value of Tata Group companies after Cyrus Mistry was shown the door earlier in the week, interim chairman Ratan Tata today met V K Sharma, the acting chairman of LIC which is one of the major investors in Tata companies. While Bombay House sources confirmed the meeting between Tata and Sharma, they refused to share what transpired between the two. Tata Group officials also met other leading domestic fund houses to allay fears about the investors worries following the dramatic developments in the nation's largest corporate group. Life Insurance Corporation (LIC) has an exposure of over Rs 37,500 crore to different Tata Group companies whose market cap eroded by over 5 per cent since the dramatic development on Monday when Mistry was summarily sacked and Tata took over.
