After posting a record annual loss and its worst fiscal year ever, Sony offered investors a light at the end of the tunnel, predicting a profitable 2013. Under new president and CEO Kazou Hirai, the company has announced cost-cutting moves including a workforce reduction of 10,000 or 6 percent of its work force. What Sony needs even more than lower overhead is people who can create the kinds of innovations that made it famous decades ago. Sony announced a $5.7 billion loss for the fiscal year and a $3.2 billion loss for the quarter. Year over year, sales dropped 18.5 percent in its core consumer products and services unit. The company blamed lower prices and unit sales for its TVs and PlayStation game consoles. Sales of digital cameras and PCs suffered because of manufacturing disruptions caused by the earthquake and flooding Japan experienced last year.
