"Tata Steel holds a 24.21 per cent stake"

"NMDC plans to join hands with Tata Steel to wrest majority control of Australian firm Riversdale Mining"

"...Som (NMDC)...hinted at a 10 per cent stake acquisition...Whatever it takes to have a majority,

"Brazils Companhia Siderurgica Nacional (CSN) has a 16.29 per cent stake"

If CSN's stake is combined with Tata's and NMDC acquires a 10% shareholding they would then have majority control in Riversdale.
