Here we go again: The Microsoft layoffs (fiscal 2016 edition) are here, and they are significant. The company MSFT plans to cut up to 7,800 positions primarily in its phone business and will record an impairment charge of about $7.6 billion related to acquisition of the Nokia devices and services business. That comes in addition to a restructuring charge of between $750 million and $850 million.

Not so long ago, Microsoft CEO Satya Nadella warned of tough choices ahead. The fact that most of the cuts come from the company’s phone business is not a surprise. In a recent reorganization, the company’s phone business was merged into the overall Windows-and-devices group led by Terry Myerson. Phone chief Stephen Elop left the company.

From the company statement:

Based on the new plans, the future prospects for the Phone Hardware segment are below original expectations. Accordingly, the company concluded that an impairment adjustment of its Phone Hardware segment assets and goodwill of approximately $7.6 billion is required.

The restructuring costs will cover the costs of layoffs; the impairment charge has to do with how the company accounts for the worth of Nokia from an accounting perspective and does not mean that Microsoft will lose $7.6 million from its balance sheet, a spokesman said. Basically, the future performance of Nokia is not what Microsoft anticipated, which in turn led restructuring and sales of some parts of that business. More details will be forthcoming in Microsoft’s 10K filing on July 21.

The spokesman added that the cuts are all about focusing the company on core businesses, which is why it just sold some of its mapping business and ad sales business to AOL. “We want to concentrate on where we can add value,” he told Fortune.

The news comes about one year after Microsoft launched its largest-ever layoffs: 18,000. Microsoft’s last published headcount number from June of last year was 128,000; the pre-layoff count this spring was likely around 118,000.
