I dug this up on their web site:

On 29 January 2009, Xstrata plc announced a proposed rights issue (the “Rights Issue”) of up to 1,982,508,352 new Ordinary Shares (“New Shares”), at a price per New Share of 210 pence, which is less than 95 per cent. of the Current Market Price per Ordinary Share. The Rights Issue was conditional on, amongst other things, Shareholders’ approval of an increase in the Xstrata plc’s share capital to create sufficient Ordinary Shares for the Rights Issue, the granting of authority to the directors of Xstrata plc to allot and issue the New Shares and to disapply pre‑emption rights. Following satisfaction of the conditions to the Rights Issue, Xstrata plc now announces an adjusted Exchange Price for the Bonds. The actual number of New Shares being offered pursuant to the Rights Issue is 1,955,341,080...........RL
