Summary of Significant Accounting Policies |
Principles of Consolidation | Principles of Consolidation ​ The accompanying unaudited consolidated financial statements include the accounts of Reliance, Inc. and its subsidiaries (collectively “Reliance”, the “Company”, “we”, “our” or “us”). These financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the consolidated financial statements reflect all material adjustments, which are of a normal recurring nature, necessary for presentation of financial statements for interim periods in accordance with GAAP. Interim results are not necessarily indicative of the results for a full year. All significant intercompany accounts and transactions have been eliminated. The ownership of the other interest holders of consolidated subsidiaries is reflected as noncontrolling interests. Investments in unconsolidated subsidiaries are recorded under the equity method of accounting. These consolidated financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and accompanying notes included in Reliance’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024. ​ The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our consolidated financial statements and the accompanying notes. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.
Inventories | Inventories ​ The majority of our inventory is valued using the last-in, first-out (“LIFO”) method, which is not in excess of market. Under this method, older costs are included in inventory, which may be higher or lower than current costs. We estimate the effect of LIFO on interim periods by allocating the projected year-end LIFO calculation to interim periods on a pro rata basis.
Recently Issued Accounting Standards | Recently Issued Accounting Standards ​ Improvement to Income Tax Disclosures—In December 2023, the Financial Accounting Standards Board (“FASB”) issued changes to expand the disclosure requirements for income taxes. The changes require disaggregated information about our effective tax rate reconciliation and income taxes paid. These changes are effective for our annual periods beginning with our 2025 fiscal year. As the guidance only requires additional disclosure, there will be no impact to our results of operations, financial condition or cash flows. ​ Disaggregation of Income Statement Expenses—In November 2024, the FASB issued changes to expand the disclosure requirements for specific expense categories. The changes require disaggregated quantitative disclosure, in the notes to the financial statements, of prescribed expense categories included within relevant income statement expense captions. These changes will be effective beginning with our 2027 fiscal year and subsequent interim periods, with early adoption permitted. As the guidance only requires additional disclosure, there will be no impact to our results of operations, financial condition or cash flows.
