1 Segment profit (loss) is an important measure used for evaluating performance and for decision-making purposes. Segment profit (loss) for the manufacturing segments excludes interest expense, certain corporate expenses, gains/losses on major business dispositions, special charges and an inventory charge related to a restructuring plan initiated in the second quarter of 2020. The measurement for the Finance segment includes interest income and expense along with intercompany interest income and expense.
2 In 2020, we initiated a restructuring plan to reduce operating expenses through headcount reductions, facility consolidations and other actions in response to the economic challenges and uncertainty resulting from the COVID-19 pandemic. The restructuring plan primarily impacted the TRU Simulation + Training business within the Textron Systems segment and the Industrial and Textron Aviation segments. In connection with this plan, we incurred special charges of $25 million in 2021, and $108 million in 2020. Special charges in 2020 also included the impairment of indefinite-lived trade name intangible assets totaling $39 million, primarily in the Textron Aviation segment.
3 On January 25, 2021, we completed the sale of TRU Simulation + Training Canada Inc. which resulted in an after-tax gain of $17 million.
4 In connection with the restructuring plan described above, we ceased manufacturing at TRU’s facility in Montreal, Canada, resulting in the production suspension of our commercial air transport simulators. As a result of this action and market conditions, we recorded a $55 million charge in the second quarter of 2020 to write-down the related inventory to its net realizable value. In the fourth quarter of 2020, we reached a definitive agreement to sell TRU Simulation + Training Canada Inc. which resulted in the recognition of an $8 million tax benefit.
5 Adjusted income from continuing operations and adjusted diluted earnings per share exclude special charges, net of tax. We consider items recorded in special charges, such as enterprise-wide restructuring, certain asset impairment charges, and acquisition-related restructuring, integration and transaction costs, to be of a non-recurring nature that is not indicative of ongoing operations. In addition, we have excluded certain impacts of the enterprise-wide restructuring plan on TRU Simulation + Training Canada Inc. (TRU Canada) that are not included within special charges, but are of a non-recurring nature and are not indicative of ongoing operations. At TRU Canada, an inventory charge is excluded as it relates to the write-down of inventory in connection with an action taken under the restructuring plan as described above. In addition, the tax benefit and the after-tax gain related to TRU Canada are both excluded as they were incurred in connection with the enterprise-wide restructuring plan.
