The rest of the cuts will be spread out, spokesman Fred Laberge said. Aetna operates in all 50 states. He added that the insurer is not pulling out of any one location or market.
"We're trying wherever possible just to combine efforts," he said. "It's not eliminating one area, it's just cutting back in a variety of staff areas."
Employees were notified Wednesday. Each person will receive nine weeks of salary, and additional severance will be based on the employee's length of service with Aetna.
The insurer announced the cuts a day after the company reassured analysts in a conference call that it remains financially strong and expects earnings growth next year. Aetna Chief Executive Ronald A. Williams repeated that message in a statement released today.
"These actions will reduce our operating costs and allow us to manage through the economic downturn from a position of strength," he said in the statement. "The fundamentals of our business are solid, and we continue to win in the marketplace."
Laberge said Tuesday's call with analysts focused on the company's overall health and its investment portfolio. Wednesday's action was more of a reaction to the current economy. He noted that Aetna has added more than 5,700 jobs since March 2007.
"You can think about this as a scaling back of that growth because of the economic downturn," he said.
Aetna warned employees last month that it planned "selective" staff cuts to help deal with a slowdown expected to continue into next year.
Managed-care companies lose business when their employer customers cut jobs and decrease the number of people covered by insurance. Aetna, with a medical enrollment of 17.7 million people, is the third-largest U.S. managed-care company, trailing only WellPoint Inc. and UnitedHealth Group Inc. Aetna employs 36,208 people.
The company will take a charge of about $35 million in the fourth quarter for the moves.
Aetna shares fell 3 cents to $24.77 in Wednesday afternoon trading.
