​ (4) The Peer Group TSR set forth in this table utilizes the Standard & Poor’s 500 Information Technology Services Index (“S&P 500 IT Services Index”), which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the Company and in the S&P 500 IT Services Index, respectively. ​ (5) We determined non-GAAP operating profit to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2024. Non-GAAP Operating Profit is defined as GAAP Operating Income excluding pretax post-retirement expense, pretax charges in connection with cost-reduction activities, non-operational legal reserves, loss on debt exchange transactions and other non-operational income/expense. Non-GAAP Operating Profit is subject to adjustment by the CEO and the CHRC of the Board for special items related to discontinued operations, reorganizations, restructurings or significant non-operational items. For a discussion and reconciliation of our GAAP measures to non-GAAP measures, please see Appendix A to this Proxy Statement and the earnings release attached as Exhibit 99.1 to our Current Report on Form 8-K furnished with the SEC on February 18, 2025 (but such report shall not be deemed to be incorporated by reference to this Proxy Statement). |  |  |  |
