Adobe Systems Inc, the top maker of design software, said that it has cut 680 jobs, or 9% of its workforce before a recent acquisition, as it moves to slash expenses.

Like many companies, Adobe has been laying off workers the past few years as the recession has cut into sales in a bid to stem the impact of the revenue decrease on profits.

The company will take between USD 65 million and USD 71 million in pretax restructuring charges related to the cuts, which will not affect employees who worked for Omniture Inc, which Adobe acquired October 23.

As of September 15, Adobe had 7,564 employees.

Adobe had previously announced that it would lay off about 9% of the 1,200 employees who joined the company through its acquisition of Omniture.

Adobe shares were unchanged in after-hours trade at USD 36.60.
