In September 2020, we initiated a restructuring plan focused on optimizing our manufacturing footprint and improving operational efficiency by better utilizing our systems capabilities. This plan includes transitioning certain administrative functions to a shared service center, realignment of manufacturing locations, and certain other efficiency improvement actions ("September 2020 Plan"). The restructuring cost of the plan is estimated to be in the range of $4,600 and $6,000, including workforce reduction charges, building and equipment relocation charges, other contract and asset related costs. In addition to these charges, we expect an additional $4,000 to $5,100 of other costs to be incurred related to the initiatives that would not qualify as restructuring charges. These costs would include certain employee overlap and training costs as well as additional capital expenditures. Restructuring charges under this plan were $1,422 during the year ended December 31, 2020, consisting of $812 of workforce reduction costs, $300 of asset impairment charges (see Note 8) and $310 of other contract termination and facility closure costs. The total restructuring liability related to the September 2020 Plan was $512 at December 31, 2020.

In June 2016, we announced plans to restructure operations by phasing out production at our Elkhart, IN facility and transitioning it into a research and development center supporting our global operations ("June 2016 Plan"). Additional organizational changes were also implemented in various other locations. In 2017, we revised this plan to include an additional $1,100 in planned costs related to the relocation of our corporate headquarters in Lisle, IL and our plant in Bolingbrook, IL, both of which have now been consolidated into a single facility. Restructuring charges under this plan, which is substantially complete, were $(32), $4,284, and $4,559 during the

years ended December 31, 2020, 2019, and 2018, respectively. The total restructuring liability related to the June 2016 Plan was $3 and $233 at December 31, 2020 and 2019, respectively. Any additional costs related to product line movements, equipment charges, and other costs will be expensed as incurred.

In April 2014, we announced plans to restructure our operations and consolidate our Canadian operations into other existing facilities as part of our overall plan to simplify our business model and rationalize our global footprint ("April 2014 Plan"). These restructuring actions were substantially completed during 2015. Restructuring charges under this plan were $0, $(248), and $503 during the years ended December 31, 2020, 2019, and 2018, respectively. The total restructuring liability related to the April 2014 Plan was $839 and $703 at December 31, 2020 and 2019, respectively. The remaining liability is expected to be settled in the first half of 2021.

From time to time we incur other restructuring activities that are not part of a formal plan. During the years ended December 31, 2020 and 2019, we incurred restructuring charges of $442 and $3,412, respectively, for exit and disposal activities at three sites and workforce reduction costs across the company. The remaining restructuring liability associated with these actions was $9 and $1,057 at December 31, 2020 and December 31, 2019, respectively.
