Mumbai: Sanjay Dangi-promoted NBFC Authum Investment & Infrastructure has invoked guarantees issued by Anil Ambani-promoted Reliance Infrastructure ( RInfra ) and Reliance Power ( RPower ) to the erstwhile Reliance Commercial Finance (RCFL) and Reliance Home Finance ( RHFL ), and converted ₹1,043 crore of debt of the two companies into equity. Boards of RInfra and RPower approved the preferential allotment on Saturday following which a notice was issued for shareholder approval on Sunday. Authum had completed the takeover of Anil Ambani companies RCFL and RHFL through a lender-led process in October and March, respectively.
