Construction and mining company Leighton Holdings has taken full ownership of its joint venture in India, Leighton Welspun.
The company acquired the Welspun Group's 39.9 per cent stake in the joint venture for $US99 million ($A112.05 million), giving it 100 per cent ownership.
Leighton will rename the business Leighton India.
The joint venture was established in 2010 to capitalise on opportunities in the Indian infrastructure sector.
Leighton said the opportunity to acquire the Welspun stake arose from Welspun's decision to reposition its infrastructure business and focus on its other activities, which include textiles, pipes energy and steel.
Leighton will review the operations of Leighton India and consider integrating several business units to lower costs.
The company said its 2013 underlying profit would not be affected by the transaction, which is expected to be completed in the first quarter of 2014.
Leighton's forecast underlying profit remains in the range of $520 million to $600 million.
Shares in Leighton dropped 15 cents to $16.11.
