| (iv) | Reflects the amounts reported in the “Change in Pension Value and Nonqualified Deferred Compensation Earnings” column of the Summary Compensation Table for the covered years.
| (v) | These amounts reflect the actuarially determined service cost for services rendered during the applicable year. The Company’s legacy non-contractual defined benefit pension plan was terminated effective December 31, 2017, and fully liquidated as of December 31, 2019. Therefore, no services costs were incurred in any of the covered years.
(2) | Total Shareholder Return (TSR) is calculated assuming $100 was invested on December 31, 2020, with reinvestment of dividends. All calculations have been prepared by Zacks Investment Research, Inc.
(3) | The 2025 peer group includes the following companies: Covenant Logistics Group, Inc., Forward Air Corporation, Hub Group, Inc., J.B. Hunt Transport Services, Inc., Knight-Swift Transportation Holdings Inc., Landstar System, Inc., Old Dominion Freight Line, Inc., RXO, Inc., Saia, Inc., Schneider National, Inc., TFI International Inc., Werner Enterprises, Inc., and XPO, Inc. Our 2025 peer group is identical to our 2024 peer group.
(4) | Net income as reported in the Company’s audited financial statements for each covered year, which includes, for the applicable years, income from discontinued operations.
(5) | Reflects the one-year and three-year average Adjusted ROCE of the Company as approved by the Compensation Committee for purposes of the Company’s annual cash incentive compensation plan and long-term cash incentive compensation plan for each covered year. The Company has determined that one-year Adjusted ROCE as used in its annual cash incentive compensation plan is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link CAP to the Named Executive Officers, for the most recently completed fiscal year, to Company performance. Because the Company uses three-year average Adjusted ROCE in its long-term cash incentive program as discussed in greater detail in “Compensation Discussion & Analysis — Components of Compensation — Long-Term Incentive Compensation,” the Company is providing, on a supplemental basis, its three-year average Adjusted ROCE for each covered year. For more information, see the section below titled “Financial Performance Measures.”

Compensation Actually Paid vs. Total Shareholder Return | CAP vs. Company TSR and Peer Group TSR The following graph compares the CAP to Ms. McReynolds and the average amount of CAP to the Non-PEO NEOs with the Company’s cumulative TSR and the peer group TSR over the five years presented. TSR is calculated assuming $100 was invested on December 31, 2020, with reinvestment of dividends. The Company’s cumulative TSR over the five-year period was $178.25 while the cumulative TSR of the peer group was $155.71 over the same period. CAP VS. COMPANY TSR AND PEER GROUP TSR ​ |  |  |  |
Compensation Actually Paid vs. Net Income | CAP vs. Net Income The following graph compares the CAP to Ms. McReynolds and the average amount of CAP to the Non-PEO NEOs with our net income over the five years presented. While we do not use net income as a compensation performance metric in our executive compensation program, the measure of net income may correlate to Adjusted Operating Income, which we use in our AIP. Because a significant portion of CAP is comprised of equity awards, which have multi-year vesting periods, CAP is more heavily impacted by fluctuations in stock price year-over-year, as compared to net income. CAP VS. NET INCOME ​ ​ ​ |  |  |  |
Compensation Actually Paid vs. Company Selected Measure | CAP vs. Annual and Three-Year Average Adjusted ROCE The following graph compares the CAP to Ms. McReynolds and the average amount of CAP to the Non-PEO NEOs with (i) our one-year Adjusted ROCE, calculated in accordance with our AIP, and (ii) on a supplemental basis, the average three-year Adjusted ROCE, calculated in accordance with our C-LTIP program, each over the five years presented. While the Company uses several financial performance measures to evaluate performance for purposes of its executive compensation program, the Company has determined that one-year Adjusted ROCE as used in the AIP is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link CAP to the Named Executive Officers, for the most recently completed fiscal year, to Company performance.

Tabular List, Table | As described in greater detail in “Executive Compensation — Compensation Discussion & Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. The financial performance measures set forth in the table below (in unranked order), in the Company’s assessment, represent the most important financial performance measures used by the Company to link CAP to the Company’s named executive officers, for the most recently completed fiscal year, to the Company’s performance. The measures are utilized in our annual incentive compensation plan (“AIP”) and our cash long-term incentive compensation plan (“C-LTIP”) and are designed with the objective of aligning the executives’ interests with those of the Company’s stockholders.
