Alcoa Shares Rise on Report Australian Mining Companies May Bid

Pittsburgh (AP) -- Shares of Alcoa Incorporated rose six percent Tuesday.

The increase came after published reports that two Australian mining companies are independently considering making bids of about $40 billion for the US aluminum producer.

They are BHP Billiton and Rio Tinto, both based in Melbourne, Australia.

Alcoa's operations include a plant employing about 2,000 in Alcoa, Tennessee.

Alcoa officials are not commenting on the report.
