<p>An Australian record net profit of US$6.17bn ($7.93bn), a share buyback and the retirement of chief executive Chip Goodyear by the end of the calendar year were the highlights of BHP Billiton’s interim results released today (Wednesday, February 7).</p> <p>Iron ore, much of it from Australia, performed solidly.</p> <p>“Underlying EBIT [earnings before interest and tax] was US$1,406m up US$163m or 13.1% from the same period last year,” the company said.</p> <p>“Sales volumes were also 6% higher, reflecting record production levels at Western Australia Iron Ore and a number of business improvement initiatives implemented to promote increased shipping efficiency.” </p> <p>Cost increases – including for labour, contractors, raw materials, fuel and energy – came to US$530m, with Australia again to the fore.</p> <p>“Specific areas of cost increases include changed mining conditions particularly at Ekati where we are mining a lower grade zone and higher strip ratios at Queensland Coal,” the company said</p> <p>However, its metallurgical coal operations suffered, falling 30% or US$288m to US$659m. </p> <p>“This was attributable mostly to lower prices for all products at Queensland Coal where benchmark prices will again decrease for the 12 months commencing April 2007,” the company said. </p> <p>“Operating costs rose due to the first longwall change out at the Broadmeadow mine, which was commissioned during 2006 and higher strip ratios at open-cut mines. </p> <p>“A stronger A$/US$ exchange rate had an unfavourable impact as did Australian inflationary pressures. </p> <p>“This was offset partially by increased production and sales at both Queensland Coal and Illawarra Coal. </p> <p>“The ramp up of expanded capacity supported by increased throughput at our Hay Point Coal terminal contributed to the higher sales at Queensland Coal.” </p> <p>The view was brighter in the energy coals sector, with an 18.5% or US$38m increase to US$243m, mostly driven by South Africa.</p> <p>“Higher production volumes and cost efficiencies at Hunter Valley Coal (Australia) and Cerrejon Coal (Colombia) had a favourable impact,” the company said.</p> <p>More generally, the drive from China was expected to continue and the outlook for the world economy for the year was bright.</p> <p>"China is set to continue as the main driver of demand, but more mature markets may also lend support, especially Europe and Japan,” the company said.</p> <p>Chairman Don Argus hailed Mr Goodyear’s “key role in the transformation of BHP Billiton since 1999”.</p> <p>For his part, Mr Goodyear said: "It has been a privilege and a pleasure to work with an outstanding team of people at BHP Billiton during a tremendous period in the company’s history.†But after nine years with the company, and what will be five years as chief executive, I have decided it is an appropriate time for the organisation to transition to the next generation of leadership.</p> <p>Meanwhile, in New York, Diana Shipping confirmed it would acquire for US$98m a capsize bulk carrier under construction in China as its third vessel on charter to BHP Billiton Marketing for four years, with one-year optional extensions. </p> <p>Total charter revenue during the four years would be US$57.4m, the company said.</p> <p>Diana Shipping chairman Simeon Palios said: “With this fixture, Diana Shipping enhances its relationship with BHP Billiton and at the same time improves the visibility of its earnings.”</p> <br />
