Pay vs Performance Disclosure |  |  |  |  |
Pay vs Performance Disclosure, Table | Pay versus performance As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, we are providing the following information regarding certain executive pay and performance. The table below shows, for each applicable fiscal year, total compensation (“Summary Compensation Total” or “SCT Total”) as reported in the summary compensation table and “compensation actually paid” (or “CAP”) for our principal executive officer (“PEO”) and as an average of all of our other named executive officers for that year (“Non-PEO NEOs”). Both SCT Total pay and CAP are calculated in accordance with the requirements of Regulation S-K and may differ substantially from the manner in which the Compensation Committee makes decisions regarding executive pay. See the “Compensation discussion and analysis” section of this proxy statement for a discussion of the Compensation Committee’s decisions regarding the compensation of our named executive officers. The table below also shows (i) the company’s cumulative total shareholder return (or “TSR”), (ii) the TSR of the S&P 1500 Steel Sub-Industry Index, which we have used as our peer group for purposes of disclosure in the table below, (iii) the company’s net income for the applicable fiscal year, and (iv) the company’s performance with respect to a “company-selected measure” (or “CSM”) which in our assessment represents the single most important financial performance metric used to link compensation actually paid to our named executive officers for the most recently completed fiscal year to the company’s performance. We selected Adjusted EBITDA as the CSM required for disclosure in the table below.

(1) | In accordance with the requirements of Item 402(v) of Regulation S-K, CAP is calculated by beginning with the SCT Total as reported in the Summary Compensation Table (the “SCT”) for the applicable fiscal year, then (a) subtracting the grant date fair value of awards reported in the Stock Awards column of the SCT for such year, (b) subtracting the grant date fair value of awards reported in the Option Awards column of the SCT for such year, (c) subtracting the aggregate change in the actuarial present value of the accumulated benefit under defined benefit plans reported in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column of the SCT for such year, (d) adding the change in fair value of stock and option awards for the applicable fiscal year (as such changes are described below for 2024) and (e) adding the service cost and prior service cost for all defined benefit plans for the applicable fiscal year (as such costs are described below for 2024).
| For purposes of determining CAP, fair value amounts for Stock Awards and Option Awards were calculated in a manner consistent with the fair value methodology used to account for share-based payments in our financial statements under GAAP, including the use of a lattice valuation model, the Monte Carlo simulation, to value performance shares. The service cost and prior service cost for defined benefit plans were calculated using the same methodology as used for our financial statements under GAAP. Neither of the individuals serving as PEO during the years covered by the table participated in any defined benefit pension plan sponsored by the company.
| For 2024, 2023, 2022 and 2021, Michael S. Williams is included in the table as PEO, and for 2020, Terry L. Dunlap is included in the table as PEO.
| The following is a reconciliation of SCT Total and CAP for the PEO for 2024. Please note that, while similar adjustment information was provided in our 2024 proxy statement for 2023 and in our 2023 proxy statement for years 2020, 2021 and 2022, under applicable SEC guidance, repeating such adjustment information is not required in this proxy statement because it is not material to our shareholders’ understanding of the information reported in the table above for 2024 or the relationships disclosures provided below.

Adjusted EBITDA is a non-GAAP measure.
