LONDON, March 4 (Reuters) - Commodities trader and mining group Glencore Xstrata Plc has raised its estimate of the savings it expects following last year's Xstrata acquisition, as it focuses on cost-cutting and targets higher returns for shareholders.
After being hammered by billion of dollars in writedowns as falling metal prices dented their assets' value, miners have worked to trim costs and tidy their balance sheets.
The group, which completed the record-breaking acquisition of Xstrata in May, was also victim of souring sentiment in the mining sector and in August announced a $7.5 billion impairment on the assets it inherited from the miner.
But the company, whose interests range from a 44 percent stake in the Collahuasi mine in Chile, one of the world's largest copper mines, to a trading hub in its hometown of Baar, Switzerland, has identified cost and efficiency savings from the acquisition of more than $2.4 billion.
That compares with guidance of $2 billion given late last year.
The full benefit of the savings will be realised this year, the company said as it posted a forecast-beating core profit in the first set of annual results since the creation of the enlarged group in May 2013.
"That's a figure that we will continue to work on," Chief Executive Ivan Glasenberg said. "We believe there are more cost savings and synergies to be obtained."
The extra savings are related mainly to reduced costs of financing, procurement and a further headcount cull.
Glencore said its annual adjusted earnings before interest, tax, depreciation and amortisation (EBITDA) totalled $13.1 billion, above a company-provided analyst consensus of $12.3 billion.
The beat was driven by a solid performance by its trading arm, offsetting a slight decline at its mining division due to weaker commodity prices.
Copper was the group's best performing commodity, with higher volumes and lower costs offseting a 7 percent price fall.
The red metal accounted for 42 percent of Glencore's earnings before interest and tax (EBIT) in 2013, up from 30 percent in the first half of the year.
"Today's results reinforce our thesis for Glencore Xstrata, predicated on its high copper exposure and the increasing benefit of its high grade African copper assets. We reiterate our 'outperform' rating," Bernstein Research analysts said in a note.
After the $7.5 billion writedown, Glencore had a net loss of $7.4 billion. It said it would pay an annual dividend of $0.165, up 5 percent from a year earlier and ahead of analysts' forecast of $0.152, according to Thomson Reuters I/B/E/S.
DEAL OR NO DEAL
The company said it had selected China's Minmetals as preferred bidder for the sale of its Las Bambas copper mine in Peru, which sources have said could fetch about $5 billion.
Glencore agreed to sell Las Bambas to secure approval from China's competition authorities for its takeover of Xstrata. But the sale, initially expected to be concluded by the end on 2013, has dragged on due to some of the bidders requesting further due diligence, Glasenberg said.
Now it is all about finding an agreement with the preferred bidder on price. The company also said it would allocate part the proceeds of the sale to repay its debt, which stood at $35.8 billion in 2013, against $29.5 billion in 2012.
Another portion could be invested in new assets or returned to shareholders. "How much that proportion may be will depend on the investment climate," Chief Financial Officer Steven Kalmin said.
The group will continue to look for potential acquisitions but said most of the assets put up for sale by large miners such as Rio Tinto and BHP Billiton so far did not meet its return expectations.
"That stuff is not so juicy," Glasenberg said. "The mining companies are not desperate to sell at the moment."
In the oil sector, Glencore could convert a minimum of $900 million of an outstanding loan to Russneft into an equity stake in the Russian oil company. Russneft has already repaid $1.2 billion of its debt with Glencore.
Glencore is still looking for a replacement for temporary chairman and former BP boss Tony Hayward. Glasenberg said a few candidates have been short-listed a new chairman should be appointed by the end of May.
Shares in Glencore were up more than 2 percent by 1313 GMT, outperforming a 0.4 percent rise in the mining sector .
