The new annual estimate is Sony's fourth revision of its original forecast. The company had already more than doubled its loss forecast for fiscal 2011 on April 5 to $2.9 billion, blaming floods in Thailand, poor foreign exchange rates and a failed partnership with Samsung, the world's No. 1 maker of TVs and flat screens. Kazuo Hirai, the company's new president and CEO hired 10 days ago, will take "painful steps" to revive Sony, and will unveil a "revival strategy" at a Thursday press briefing."
