ZURICH, Aug 5 (Reuters) - Swiss Re posted a surprise second-quarter net loss on Wednesday as charges on corporate bond hedges, securitised products and its own credit spreads ate up healthy operating returns.
Zurich-based Swiss Re said it made a net loss of 381 million Swiss francs ($359.1 million), against an average forecast for a net profit of 139 million in a Reuters poll of 12 analysts.
But Chief Executive Stefan Lippe said the company was still confident of delivering on its targets.
"During the second quarter of 2009, our core business, despite the reported loss, continued to deliver strong underwriting results and solid earnings power," he said.
The world's second-biggest reinsurer said its excess capital at AA level had improved to 4.5 billion francs and its cost savings would be ahead of target in 2009.
The company's combined ratio in Property and Casualty was a healthy 89.4 percent, better than 91.0 percent a year earlier. A combined ratio below 100 percent shows insurance operations are profitable.
Shares in Swiss Re were indicated to open 0.5 percent lower, premarket data provided by bank Clariden Leu showed..
The stock has fallen more than 14 percent so far this year, lagging a 2 percent rise in the European insurance index, as the reinsurer strives to earn enough to repay a costly convertible investment by Warren Buffett's Berkshire Hathaway it accepted after writing down billions on toxic assets..
Swiss Re made no comment about paying back Buffett in Wednesday's statement.
Larger German rival Munich Re said on Tuesday it expected only a small hit from the economic crisis and that it might resume share buybacks this year after posting forecast-beating earnings in the second quarter.
Swiss Re's legacy unit, which combines toxic assets teh group seeks to exit, made a profit and ended all of its credit default swap contracts, decreasing risk substantially, Swiss Re said. (Editing by David Holmes)
