New York Times: An accounting charge wiped out Microsoft’s profit for the quarter, leading to its largest loss ever, the company said, making clear the cost of its missteps in the mobile business. The $7.5 billion accounting charge, stemming from Microsoft’s troubled acquisition of Nokia’s cellphone business, was disclosed earlier this month, along with plans to eliminate 7,800 jobs. While the accounting charge was on paper and will not diminish the company’s huge cash hoard, it was a psychic blow to the company.
