Disaggregation of Revenue [Line Items] |
Revenue from Contracts with Customers | Net sales recognized from contracts with customers, disaggregated by segment and geographical location, are presented in the following table for the three months ended March 31, 2021 and 2020. Net sales are attributed to regions based on the location of production. Intersegment sales have been excluded from the table. In the first quarter of 2021, we reorganized our segments and moved certain of our Driveline facilities to our Metal Forming segment. The amounts previously reported in the tables below for the three months ended March 31 2020 have been retroactively restated to reflect this change.
