Description of the Business and Significant Accounting Policies |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of Steel Dynamics, Inc., together with its wholly- and majority-owned or controlled subsidiaries, after elimination of intercompany accounts and transactions. Noncontrolling and redeemable noncontrolling interests represent the noncontrolling owners’ proportionate share in the equity, income, or losses of the company’s majority-owned or controlled consolidated subsidiaries. Redeemable noncontrolling interests related to USS (owned 90% by SDI) are $60.0 million at March 31, 2024, and December 31, 2023. Redeemable noncontrolling interests related to Mesabi Nugget (owned 86% by SDI) are $111.2 million at March 31, 2024, and December 31, 2023.
Use of Estimates | ​ Use of Estimates These consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, and accordingly, include amounts that require management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the notes thereto. Actual results may differ from these estimates and assumptions. In the opinion of management, these financial statements reflect all normal recurring adjustments necessary for a fair presentation of the interim period results. These consolidated financial statements and notes should be read in conjunction with the audited financial statements and notes thereto included in the company’s Annual Report on Form 10-K for the year ended December 31, 2023.
Cash and Equivalents, and Restricted Cash | Cash and Equivalents, and Restricted Cash Cash and equivalents include all highly liquid investments with a maturity of three months or less at the date of acquisition. Restricted cash is primarily funds held in escrow as required by various insurance and government organizations. The balance of cash, cash equivalents and restricted cash in the consolidated statements of cash flows includes restricted cash of $5.5 million at March 31, 2024, $5.6 million at December 31, 2023, $5.5 million at March 31, 2023, and $5.5 million at December 31, 2022, which are recorded in Other Assets (noncurrent) in the company’s consolidated balance sheets.
Short-Term Investments | Short-Term Investments Short-term investments include investments with maturity dates of longer than three months but less than one year when purchased. The company’s short-term investments are classified as trading securities. Interest income from invested cash and short-term investments was $26.3 million and $26.0 million for the three-month periods ended March 31, 2024 and 2023, respectively, and is recorded in other (income) expense, net as earned. The company’s short-term investments were $653.3 million and $721.2 million as of March 31, 2024 and December 31, 2023, respectively.
Goodwill | Goodwill The company’s goodwill consisted of the following at March 31, 2024, and December 31, 2023 (in thousands):

​ | Metals Recycling Operations Segment | ​ | ​ | 203,413 | ​ | ​ | 203,413 | ​
​ | Steel Fabrication Operations Segment | ​ | ​ | 1,925 | ​ | ​ | 1,925 | ​
​ | ​ | ​ | $ | 477,471 | ​ | $ | 477,471 | ​
Credit Losses | Credit Losses The company is exposed to credit risk in the event of nonpayment of accounts receivable by customers. The company mitigates its exposure to credit risk, which it generally extends on an unsecured basis, by performing ongoing credit evaluations and taking further action if necessary, such as requiring letters of credit or other security interests to support the customer receivable. The allowance for credit losses for accounts receivable is based on the company’s reasonable estimate of known credit risks and historical experience, adjusted for current and anticipated economic and other pertinent factors affecting the company’s customers, that may differ from historical experience. Customer accounts receivable are written off when all collection efforts have been exhausted and the amounts are deemed uncollectible. ​ At March 31, 2024, the company reported $1,739.1 million of accounts receivable, net of allowances for credit losses of $8.2 million. Changes in the allowance were not material for each of the three-month periods ended March 31, 2024 and 2023.
Derivative Financial Instruments | Derivative Financial Instruments The company routinely enters into forward exchange traded futures to manage price risk associated with nonferrous metal inventory, as well as purchases and sales of nonferrous (primarily aluminum and copper) and ferrous metals, to reduce exposure to commodity related price fluctuations. The company does not enter into these derivative financial instruments for speculative purposes. The company recognizes all derivatives as either assets or liabilities in the consolidated balance sheets and measures those instruments at fair value. Derivatives that are not designated as hedges must be adjusted to fair value through earnings. Changes in the fair value of derivatives that are designated as hedges, depending on the nature of the hedge, are recognized as either an offset against the change in fair value of the hedged balance sheet item in the case of fair value hedges or as other comprehensive income in the case of cash flow hedges, until the hedged item is recognized in earnings. The ineffective portion of a derivative’s change in fair value is immediately recognized in earnings for fair value hedges. The company offsets fair value amounts recognized for derivative instruments executed with the same counterparty under master netting agreements. The fair value of the Company’s derivative instruments, along with required margin deposit amounts with the same counterparty under master netting arrangements, totaled $19.8 million at March 31, 2024, and $24.0 million at December 31, 2023, and are reflected in other current assets in the consolidated balance sheets. Total gains and losses related to derivatives in fair value hedging relationships, as well as those not designated as hedging instruments, are recognized in costs of goods sold and were not material for each of the three-month periods ended March 31, 2024 and 2023. Derivatives accounted for as cash flow hedges, for which gains and losses are recognized in other comprehensive income, along with net gains reclassified from accumulated other comprehensive income, were not material for each of the three-month periods ended March 31, 2024 and 2023.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The guidance is to be applied retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The company is currently evaluating the potential impact of adopting this new guidance on the consolidated financial statements and related disclosures. ​ Note 1. Description of the Business and Significant Accounting Policies (Continued) ​ In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures to require entities to disclose specific categories in the rate reconciliation, the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. ASU 2023-09 is to be applied on a prospective basis, but retrospective application is permitted. The company is currently evaluating the potential impact of adopting this new guidance on the consolidated financial statements and related disclosures.
