The Motorola restructuring is now expected to "include additional geographic regions outside of the U.S.," Google said Thursday in a filing by Google with the Securities and Exchange Commission, but the online search leader is not adding to the 4,000 layoffs announced in late August. The company said in August that it was planning to close or consolidate about one-third of Motorola's 90 locations. It said then that two-thirds of the job cuts, about 20 percent of Motorola's staff and 7 percent of Google's overall work force, would take place outside the U.S.
Google bought Motorola Mobility, which makes cellphones and cable set-top boxes, in late May for $12.4 billion. It was its largest acquisition ever, broadening the company's business from its roots in Internet search and other online services to manufacturing equipment.
Motorola makes phones that run on Google's Android operating software, but rivals such as Samsung Electronics have been more successful at it.
About $300 million of the charges announced Thursday are related to severance payments and will be taken in the third quarter.
The Mountain View company also expects to pay about $90 million in charges for the cost of closing facilities through 2013. About $40 million of those charges are expected to be taken in the third quarter.
That raises Google's cost for the restructuring. It had said in late August that it would book $275 million for severance payments.
Motorola may make even more cuts as it evaluates its plans, which could result in more "significant" charges, Google said.
Google shares rose $2.80 to $765.30 in late morning trading Thursday.
