In 2012, we recognized repositioning charges totaling $119 million including severance costs of $91 million related to workforce reductions of 2,204 manufacturing and administrative positions across all of our segments. The workforce reductions were primarily related to the planned shutdown of a manufacturing facility in our Transportation Systems segment, the exit from a product line in our Performance Materials and Technologies segment, and cost savings actions taken in connection with our productivity and ongoing functional transformation initiatives. The repositioning charge also included asset impairments of $12 million principally related to manufacturing plant and equipment associated with the exit of a product line in our Performance Materials and Technologies segment. The repositioning charge also included exit costs of $16 million principally related to closure obligations associated with the planned shutdown of a manufacturing facility in our Transportation Systems segment and exit from a product line in our Performance Materials and Technologies segment. Also, $66 million of previously established accruals primarily for severance at our Automation and Control Solutions, Aerospace and Performance Materials and Technologies segments were returned to income in 2012 due primarily to fewer employee severance actions caused by higher attrition than originally planned associated with prior severance programs and changes in the scope of previously announced repositioning actions.

In 2011, we recognized repositioning charges totaling $380 million including severance costs of $246 million related to workforce reductions of 3,188 manufacturing and administrative positions across all of our segments. The workforce reductions were primarily related to the planned shutdown of a manufacturing facility in our Transportation Systems segment, cost savings actions taken in connection with our ongoing functional transformation and productivity initiatives, factory transitions in connection with acquisition-related synergies in our Automation and Control Solutions and Aerospace segments, the exit from and/or rationalization of certain product lines and markets in our Performance Materials and Technologies and Automation and Control Solutions segments, the consolidation of repair facilities in our Aerospace segment, and factory consolidations and/or rationalizations and organizational realignments of businesses in our Automation and Control Solutions segment. The repositioning charges included asset impairments of $86 million principally related to the write-off of certain intangible assets in our Automation and Control Solutions segment due to a change in branding strategy and manufacturing plant and equipment associated with the planned shutdown of a manufacturing facility and the exit of a product line and a factory transition as discussed above. The repositioning charges also included exit costs of $48 million principally for costs to terminate contracts related to the exit of a market and product line and a factory transition as discussed above. Exit costs also included closure obligations associated with the planned shutdown of a manufacturing facility and exit of a product line also as discussed above. Also, $26 million of previously established accruals, primarily for severance at our Aerospace and Automation and Control Solutions segments, were returned to income in 2011 due principally to fewer employee separations than originally planned associated with prior severance programs.

In 2010, we recognized repositioning charges totaling $179 million including severance costs of $144 million related to workforce reductions of 2,781 manufacturing and administrative positions primarily in our Automation and Control Solutions, Aerospace and Transportation Systems segments. The workforce reductions were primarily related to the planned shutdown of certain manufacturing facilities in our Automation and Control Solutions and Transportation Systems segments, cost savings actions taken in connection with our ongoing functional transformation and productivity initiatives, factory transitions in our Aerospace, Automation and Control Solutions and Performance Materials and Technologies segments to more cost-effective locations, achieving acquisition-related synergies in our Automation and Control Solutions segment, and the exit and/or rationalization of certain product lines in our Performance Materials and Technologies segment. The repositioning charge also included asset impairments of $21 million principally related to manufacturing plant and equipment associated with the exit and/or rationalization of certain product lines and in facilities scheduled to close. Also, $30 million of previously established accruals, primarily for severance at our Automation and Control Solutions, Transportation Systems and Aerospace segments, were returned to income in 2010 due to fewer employee separations than originally planned associated with prior severance programs.

Certain repositioning projects in our Aerospace, Automation and Control Solutions and Transportation Systems segments included exit or disposal activities, the costs related to which will be recognized in future periods when the actual liability is incurred. The nature of these exit or disposal costs includes asset set-up and moving, product recertification and requalification, and employee retention, training and travel. The following tables summarize by segment, expected, incurred and remaining exit and disposal costs related to 2011 and 2010 repositioning actions which we were not able to recognize at the time the actions were initiated. The exit and disposal costs related to the repositioning actions in 2012 which we were not able to recognize at the time the actions were initiated were not significant.
