Rio Tinto Ltd
(ASX:RIO) has completed the second tranche of its internal capital management.
In August the mining giant said it had agreed to buy back all of the shares it holds in its wholly owned subsidiary Tinto Holdings Australia Pty Ltd.
The buyback was expected to be undertaken in two tranches, the first of which was completed on 27 August.
Rio today says that it has bought back the remaining shares, over 20 million shares at $75.13 per share.
Rio says these shares will be now cancelled, so the number of shares held by public shareholders is not affected.
In the six months to 30 June 2010, Rio Tinto reported a $7.37 billion profit.
