PARIS, Aug 1 (Reuters) - French bank Societe Generale reported a worse-than-expected 42 percent drop in second-quarter earnings on Wednesday, hit by one-off write-downs on U.S. fund unit TCW and Russian subsidiary Rosbank.
France's No. 2 listed bank is more than halfway through a plan to slash debt and sell assets at its corporate and investment bank. It is under pressure to beef up balance-sheet strength and sources have told Reuters a sale of TCW is close.
Net income fell to 433 million euros ($533.3 million), missing the average of analyst estimates of about 677.9 million according to a Reuters poll. Revenue fell 3.6 percent to 6.27 billion euros, better than the poll average of 6.13 billion.
In addition to write-downs totalling 476 million euros, which SocGen blamed on the worsening environment for fund managers in the case of TCW and a strategic overhaul at Rosbank, SocGen took a hit on the cost of selling assets to cut debt.
SocGen Deputy Chief Executive Officer Severin Cabannes told Reuters Insider television it was difficult to make forecasts in the current environment but said the pain of asset sales would ease. He refused to say whether TCW was up for sale.
"We will continue to deleverage (but) at a lower pace than the two previous quarters," he said. "It will still have an impact."
Commenting on how the European Central Bank might revive confidence amid the euro debt crisis, Cabannes said that overall liquidity in the euro zone was "good" and that a third wave of cheap loans to the banking sector was unlikely.
He said other measures such as asset purchases would give a boost.
SocGen said it was confident it would hit an end-2013 target of a Basel III core Tier 1 ratio of between 9 and 9.5 percent.
Cabannes said SocGen was cooperating with authorities investigating the Libor rate-fixing scandal, which has rocked the industry and cost the job of top Barclays executives.
No allegations of wrongdoing have been made against SocGen after the bank answered regulators' questions, he told Reuters Insider.
"We are continuing to cooperate," he said.
Asked whether internal checks had been made, he replied: "To address the requests from the regulators we have to do internal requests (for information)."
SocGen's corporate and investment bank, which has cut back on risk since a huge rogue trading loss in early 2008 hammered its reputation, saw second-quarter profits sink 70 percent.
The impact of the global economic slowdown, the cost of selling loan portfolios and losses from toxic assets left over from the last financial crisis all weighed, said SocGen.
Rivals have also felt the pain of euro zone turmoil: Deutsche Bank said last month it would cut 1,500 investment-banking jobs after a profit slump, while Switzerland's UBS swung to an investment-banking loss in the quarter.
Investors will be watching to see whether SocGen's domestic arch-rival BNP Paribas held up better when it reports results on Thursday. The bank is seen clearing a key regulatory capital hurdle, stealing a march on SocGen in the early stages of an industry-wide race.
