In September 2020, we initiated a restructuring plan focused on optimizing our manufacturing footprint and improving operational efficiency by better utilizing our systems capabilities (the "September 2020 Plan"). This plan includes transitioning certain administrative functions to a shared service center, realignment of manufacturing locations, and certain other efficiency improvement actions. The restructuring cost of the September 2020 Plan is now estimated to be in the range of $3,500 and $4,500, including workforce reduction charges, building and equipment relocation charges and other contract and asset-related costs. We have incurred $1,555 in program costs to date. We recorded $158 in workforce reduction costs during the three and six months ended June 30, 2022 under the 2020 Plan. Due to the robust market demand and COVID-19 limitations, some projects have been delayed. The total restructuring liability associated with these actions was $158 as of June 30, 2022. There was no liability related to the September 2020 Plan as of December 31, 2021.

From time to time we undertake other restructuring activities that are not part of a formal plan. During the three and six months ended June 30, 2022, we incurred restructuring charges of $470 and $782, respectively. During the three and six months ended June 30, 2021, we incurred restructuring charges of $161 and $262, respectively. The total restructuring liability associated with these actions was $723 at June 30, 2022 and $962 at December 31, 2021.
