In the quarter ended March 31, 2019, we recognized gross repositioning charges totaling $60 million including severance costs of $31 million related to workforce reductions of 1,047 manufacturing and administrative positions mainly in Corporate, Aerospace and Honeywell Building Technologies. The workforce reductions were primarily related to our productivity and ongoing functional initiatives and to site transitions in Aerospace to more cost-effective locations.

In the quarter ended March 31, 2018, we recognized gross repositioning charges totaling $86 million including severance costs of $31 million related to workforce reductions of 1,153 manufacturing and administrative positions mainly in Aerospace and Safety and Productivity Solutions. The workforce reductions were primarily related to site transitions to more cost-effective locations. The repositioning charges included asset impairments of $47 million primarily in our Corporate segment related to the write-down of a legacy property in connection with its planned disposition.
