Google Inc. (Nasdaq:GOOG) said Monday it will cut 4,000 jobs from its Motorola Mobility unit, roughly 20 percent of its current staff, and close or consolidate 30 of its 90 facilities.

About two-thirds of the cuts at Motorola Mobility, for which the Mountain View, Calif., search engine paid $12.5 billion in May, will occur outside the United States. Motorola Mobility has lost money in 14 of the last 16 quarters, The Wall Street Journal said. The layoffs will result in a charge against earnings of no more than $275 million.

Shares of Google Inc. (Nasdaq:GOOG) rose $8.21 to $650.21 in premarket trading.
