Restructuring	13. RESTRUCTURING As disclosed in the Company's Form 10-K for the fiscal year ended March 31, 2020, during the fiscal years ended March 31, 2017 and 2016, the Company committed to restructuring plans involving certain of its businesses, as well as the consolidation of certain of its facilities. With the exception of certain consolidations to be completed in future years, these plans were substantially complete as of March 31, 2020. During the three months ended June 30, 2021, the Company incurred costs of $1,038, $3,018, and $434, within Systems & Support, Aerospace Structures, and its corporate headquarters, respectively, for total restructuring costs of $4,485 associated with new restructuring plans. The restructuring costs within Aerospace Structures pertained to facility closures with the remainder primarily related to postemployment benefits arising from reductions in force and third-party consulting costs. The restructuring costs within Systems & Support and Corporate are primarily related to postemployment benefits arising from reductions in force and a lease termination. We estimate that we will incur consolidated restructuring costs of approximately $15,000 for the fiscal year ended March 31, 2022, with costs being incurred in each of our segments for third-party consulting costs and severance, primarily related to our cost-reduction initiatives.
