Brothers Shashi and Ravi Ruia's Essar Group faced a setback recently when its Essar Steel got a rating downgrade to "default" status even as it was in midst of borrowing close to $1 billion. Brothers are investing $260 million of their own money in the steelmaker. London-listed Essar Energy plans to sell its 49% stake in a Kenyan refinery it found unviable to upgrade. Brothers meanwhile are looking to unload one of their Delhi mansions for over $25 million.
