Non-GAAP measure definitions Adjusted earnings or loss per share (EPS) Adjusted earnings or loss per share is a non-GAAP measure calculated by excluding restructuring, integration and acquisition costs, and impairments and other gains and losses arising from significant strategic transactions or material events, after tax, as well as significant one-time tax items from the diluted earnings per share from continuing operations attributable to equity holders of the Company. The effect per share is obtained by dividing these restructuring, integration and acquisition costs and other gains and losses, after tax, as well as one-time tax items by the average number of diluted shares. We track it because we believe it provides a better indication of our operating performance on a per share basis and facilitates the comparison across reporting periods. Adjusted earnings or loss per share excluding COVID-19 government support programs further excludes the impacts of government contributions related to COVID-19 support programs that were credited to income, after tax, but does not adjust for COVID-19 heightened operating costs that we have been carrying and that have been included in our results. Adjusted net income or loss Adjusted net income or loss is a non-GAAP measure we use as an alternate view of our operating results. We calculate it by taking our net income attributable to equity holders of the Company from continuing operations and excluding restructuring, integration and acquisition costs, and impairments and other gains and losses arising from significant strategic transactions or material events, after tax, as well as significant one-time tax items. We track it because we believe it provides a better indication of our operating performance and facilitates the comparison across reporting periods. Adjusted net income or loss excluding COVID-19 government support programs further excludes the impacts of government contributions related to COVID-19 support programs that were credited to income, after tax, but does not adjust for COVID-19 heightened operating costs that we have been carrying and that have been included in our results. Adjusted segment operating income or loss (SOI) Adjusted segment operating income or loss is a non-GAAP measure and is the sum of our key indicators of each segment's financial performance. Adjusted segment operating income or loss gives us an indication of the profitability of each segment because it does not include the impact of any items not specifically related to the segment's performance. We calculate adjusted segment operating income by taking operating income and excluding restructuring, integration and acquisition costs, and impairments and other gains and losses arising from significant strategic transactions or material events. We track it because we believe it provides a better indication of our operating performance and facilitates the comparison across reporting periods. Additionally, adjusted segment operating income or loss is the profitability measure employed by management for making decisions about allocating resources to segments and assessing segment performance. Adjusted segment operating income or loss excluding COVID-19 government support programs further excludes the impacts of government contributions related to COVID-19 support programs that were credited to income but does not adjust for COVID-19 heightened operating costs that we have been carrying and that have been included in our results. While management is aware of such further adjusted measure, it is not specifically employed by management as a profitability measure for making decisions about allocating resources to segments and assessing segment performance. Capital employed Capital employed Capital employed is a non-GAAP measure we use to evaluate and monitor how much we are investing in our business. We measure it from two perspectives: Capital used: For the Company as a whole, we take total assets (not including cash and cash equivalents), and subtract total liabilities (not including long-term debt and the current portion of long-term debt); For each segment, we take the total assets (not including cash and cash equivalents, tax accounts and other non-operating assets), and subtract total liabilities (not including tax accounts, long-term debt and the current portion of long-term debt, royalty obligations, employee benefit obligations and other non-operating liabilities). Source of capital: In order to understand our source of capital, we add net debt to total equity. For a reconciliation of this non-GAAP measure to the most directly comparable measure under GAAP, refer to section 9.1 "Consolidated capital employed" of the interim MD&A for the periods ending June 30, 2020, September 30, 2020 and December 31, 2020 (as filed on SEDAR (www.sedar.com) on August 12, 2020, November 10, 2020 and February 12, 2021, respectively), as well as section 7.1 "Consolidated capital employed" of the financial report for the years ended March 31, 2018, March 31, 2019, March 31, 2020 and March 31, 2021 (as filed on SEDAR (www.sedar.com) on May 25, 2018, May 17, 2019, May 22, 2020, and May 19, 2021 respectively), which sections are specifically incorporated by reference into this presentation. Return on capital employed (ROCE) ROCE is used to evaluate the profitability of our invested capital. We calculate this ratio over a rolling four-quarter period by taking net income attributable to equity holders of the Company excluding net finance expense, after tax, divided by the average capital employed. 52 37 CAE Inc.
