IBM has confirmed it plans to reduce its work force by up to 13,000 employees, mainly in Europe.

The move is part of a global restructuring effort aimed at shifting resources to higher-growth markets.

The company will take a $1.3 billion to $1.7 billion pre-tax charge related to the restructuring in the second quarter, IBM said.

The company has already initiated discussions for voluntary and involuntary work force reductions, IBM said.
