In 2015, Microsoft took a US$7.8 billion write-down on the Nokia purchase, and announced layoffs of 7,800 employees, primarily within Microsoft's phone business. In May 2016, Microsoft abandoned its mobile business, selling the Nokia feature phone line and trademark rights to the Finnish startup HMD Global, and announcing that it planned to cut up to 1,350 positions in Finland and focus on offering its productivity services on competing mobile platforms. In 2017, Microsoft executive Joe Belfiore revealed that Microsoft had ceased the development of new Windows phones and new features for Windows 10 Mobile, citing the losses in market share and lack of app development.
