Schedule of Restructuring Activity

The table below details the restructuring activity for the years ended September 30, 2020 and 2019.  The activity during 2019 is primarily related to the departure of our former CEO as well as additional headcount reductions as we consolidated satellite offices in our Semiconductor segment.  The activity during 2020 is the result of staff reductions at our Massachusetts operations as we evaluated staffing across our Semiconductor operations.  The outstanding obligations as of September 30, 2020 and September 30, 2019, are as follows, in thousands:
