Restructuring and other charges

The main components of accrued non-acquisition related restructuring charges, which were recognized in fiscal year 2009, include workforce management costs associated with the early retirement and the involuntary separation of employees in connection with a strategic realignment of global workforce capacity. Restructuring charges related to fiscal year 2009 business acquisitions include a number of items such as those associated with integrating similar operations, workforce management, vacating certain facilities, and the cancellation of some contracts.
