Google plans to make an unspecified number of job cuts at DoubleClick Inc following the closing of its $3.1 billion acquisition of the advertising technology company.

“An immediate task we’ll undertake over the next few weeks is matching and aligning DoubleClick employees with our organizational plan for the business,” Google said in a blog post.

“As with most mergers, there may be reductions in headcount. We expect these to take place in the US and possibly in other regions as well,” the company said. DoubleClick has 1,500 employees. Outside of the United States, Google will begin consultations with employee organizations on potential job reductions in line with local laws, it said.
