He said his administration had expected 1,000 to 1,300 workers to be redeployed under the severance program.

She added that the Mayor was confident the severance program would reach its target.

And just last week, the exchange announced a voluntary severance program; it had already laid off 10 percent of its staff earlier this year.

The company also plans to offer a financial package similar to a severance program it has used to encourage workers to voluntarily leave their jobs.

The severance program opened yesterday and will close on Jan. 18, the administration said.

The company said 3,400 would be from its domestic work force, including 1,600 who have already resigned under a voluntary severance program.
