BHP Billiton today announced the successful completion of its off-market buy-back of 96.0 million BHP Billiton Limited shares, which comprises the first stage of its US$2 billion capital management programme. Due to the strong demand available at an attractive price, BHP Billiton increased the buy-back to A$2.25 billion (US$1.6 billion), representing 1.6% of the issued share capital of the BHP Billiton Group and 2.7% of BHP Billiton Limited.

The final price for the buy-back has been set at A$23.45 per share, representing a discount of 14% to the volume weighted average price (VWAP) of BHP Billiton Limited shares over the 5 trading days up to and including the closing date of the buy-back(1). This significant discount to market ensures the buy-back is in the best interests of BHP Billiton and all of its shareholders, regardless of their location, tax status or participation in the buy-back. The closing price for BHP Billiton Limited and the opening price for BHP Billiton Plc on 31 March 2006 were A$28.00 and 10.67 pounds(2), respectively.

BHP Billiton's Chief Financial Officer, Alex Vanselow, said "the successful execution of the off-market buy-back provides an optimal means for maximising economic value for all of our shareholders. Shareholders in both BHP Billiton Limited and BHP Billiton Plc will benefit from the enhanced value of the remaining shares through the increased earnings, cash flow and return on equity attributable to each share."

"We are pleased with the strong support that we have received from shareholders, which has enabled us to significantly increase the size of the buy-back to A$2.25 billion from the previously announced A$1.5 billion target. It is intended that the balance of US$0.4 billion will be returned to our shareholders via on-market purchases, most likely of BHP Billiton Plc shares. The Board of BHP Billiton believes that this US$2 billion capital management initiative, which is in addition to the 3 US cents per share increase in the interim dividend, demonstrates our continued commitment to capital discipline as well as our confidence in the Company's outlook and strong cash generative capabilities," Mr Vanselow said.

Due to the very strong demand for the buy-back, a scale back of tenders is required. Shareholders who tendered their shares at a 14% discount and/or as final price tenders, will have a priority allocation of 200 shares bought back before the scale back is applied. As a result of the 63.47% scale back, successful shareholders will have 36.53% of their shares tendered in excess of the priority allocation bought back. No tenders were excluded on the basis of a minimum price condition.

To ensure that registered shareholders with small holdings are not disadvantaged, the scale back has been structured so that successful shareholders who tendered all of their shares at a 14% tender discount and/or as a final price tender and who would be left with 80 shares or less as a result of the priority allocation and scale back, will have all of their shares bought back in full.

For shareholders who have successfully tendered their shares, A$21.35 of the buy-back price is treated for Australian tax purposes as a fully franked dividend. For Australian capital gains tax purposes, the deemed capital proceeds are A$5.96, being the A$2.10 capital component plus A$3.86, being the excess of the Tax Value(3) over the buy-back price.

Payments to bank accounts and dispatch of cheques for shares bought back are expected to be completed by Monday, 10 April 2006. Shares that have been tendered into the buy-back but not bought back are expected to be released to shareholders during Monday, 3 April 2006.
