Summary of Significant Accounting Policies

Principles of Consolidation

Principles of Consolidation

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. 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 U.S. GAAP for complete financial statements. In the opinion of management, our 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 U.S. GAAP. The results of operations for the nine months ended September 30, 2022 are not necessarily indicative of the results for the full year ending December 31, 2022. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto for the year ended December 31, 2021, included in the Reliance Steel & Aluminum Co. (“Reliance,” the “Company,” “we,” “our” or “us”) Annual Report on Form 10-K.

The preparation of financial statements in conformity with U.S. 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.

Our consolidated financial statements include the assets, liabilities and operating results of majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The ownership of the other interest holders of consolidated subsidiaries is reflected as noncontrolling interests. Our investments in unconsolidated subsidiaries are recorded under the equity method of accounting.

Inventories

Inventories

The majority of our inventory is valued using the last-in, first-out (“LIFO”) method, which is not in excess of market. 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 - Not Yet Adopted

Recently Issued Accounting Standards—Not Yet Adopted

Reference Rate Reform—In March 2020, the FASB issued accounting changes that provide optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The accounting changes may be applied prospectively through December 31, 2022. To the extent that, prior to December 31, 2022, we enter into any contract modifications for which the optional expedients are applied, the adoption of this standard is not expected to have a material impact on our consolidated financial position, results of operations or cash flows.
