| Summary of Significant Accounting Policies | Note 1. Summary of Significant Accounting Policie s Principles of Consolidation The accompanying consolidated financial statements include the accounts of Reliance Steel & Aluminum Co. and its subsidiaries (collectively referred to as “Reliance”, “the Company”, “we”, “our” or “us”). Our consolidated financial statements include the assets, liabilities and operating results of majority-owned subsidiaries. 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. All significant intercompany accounts and transactions have been eliminated. Business We operate a metals service center network of more than 300 locations in 40 states in the U.S. and in 13 other countries (Australia, Belgium, Canada, China, France, India, Malaysia, Mexico, Singapore, South Korea, Turkey, the United Arab Emirates and the United Kingdom) that provides value-added metals processing services and distributes a full line of more than 100,000 metal products. Since our inception in 1939, we have not diversified outside our core business as a metals service center operator. Accounting Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, such as allowances for uncollectible accounts, net realizable values of inventories, fair values and/or impairment of goodwill and other indefinite-lived intangible assets, long-lived assets, the amount of unrecognized tax benefits and other contingencies, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Accounts Receivable and Concentrations of Credit Risk Concentrations of credit risk with respect to trade receivables are limited due to the geographically diverse customer base, with limited exposure to any single customer account, and various industries into which our products are sold. Trade receivables are typically non-interest bearing and are initially recorded at cost. Sales to our recurring customers are generally made on open account terms while sales to occasional customers may be made on a collect on delivery basis when collectability is not assured. Past due status of customer accounts is determined based on how recently payments have been received in relation to payment terms granted. Credit is generally extended based upon an evaluation of each customer’s financial condition, with terms consistent in the industry and no collateral is required. Losses from credit sales are provided for in the financial statements and consistently have been within the allowance provided. The allowance is an estimate of the amount of accounts receivable that will not be collected from our customers based on an evaluation of specific customer risks along with additional reserves based on historical and probable bad debt experience. Amounts are written-off against the allowance in the period we determine that the receivable is uncollectible. As a result of the above factors, we do not consider ourselves to have any significant concentrations of credit risk. 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. This method of valuation is subject to year-to-year fluctuations in cost of material sold, which is influenced by the inflation or deflation existing within the metals industry as well as fluctuations in our product mix and on-hand inventory levels. Fair Values of Financial Instruments Fair values of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities, current maturities of operating lease liabilities and long-term debt approximate carrying values due to the short period of time to maturity. Fair values of long-term debt, which have been determined based on borrowing rates currently available to us or to other companies with comparable credit ratings, for loans with similar terms or maturity, approximate the carrying amounts in the consolidated financial statements, with the exception of our publicly traded senior unsecured notes of $750.0 million as of December 31, 2019 and 2018. The fair values of these senior unsecured notes based on quoted market prices were $840.0 million and $780.0 million at December 31, 2019 and 2018, respectively, compared to their carrying values of $745.6 million and $744.8 million, respectively. These estimated fair values are based on Level 2 inputs, including benchmark yields, reported trades and broker/dealer quotes. Fair values are generally based on quoted market prices for identical or similar instruments. Cash Equivalents We consider all highly liquid instruments with an original maturity of three months or less when purchased to be cash equivalents. We maintain cash and cash equivalents with high credit quality financial institutions. The Company, by policy, limits the amount of credit exposure to any one financial institution. Goodwill and Other Indefinite-Lived Intangible Assets Goodwill is the excess of purchase price over the fair value of identified assets and liabilities of businesses acquired. Other indefinite-lived intangible assets include amounts allocated to the trade names of businesses acquired. Goodwill and other indefinite-lived intangible assets are not amortized but are tested for impairment at least annually. We test for impairment of goodwill and intangible assets deemed to have indefinite lives annually and, between annual tests, whenever significant events or changes occur based on an assessment of qualitative factors to determine if it is more likely than not that the fair value is less than the carrying value. We have one operating segment and one reporting unit for goodwill impairment purposes. We calculate the fair value of the reporting unit using our market capitalization or the discounted cash flow method, as necessary, and compare the fair value to the carrying value of the reporting unit to determine if impairment exists. We perform our annual impairment evaluations of goodwill and other indefinite-lived intangible assets goodwill on November 1 of each year. No impairment of goodwill was determined to exist in any of the years presented. We recognized an impairment loss of $16.5 million related to our other intangible assets with indefinite lives in 2018, respectively. See Note 19 — “Impairment and Restructuring Charges” Long-Lived Assets Property, plant and equipment is recorded at cost (or at fair value for assets acquired in connection with business combinations) and the provision for depreciation of these assets is generally computed on the straight-line method at rates designed to distribute the cost of assets over the useful lives, estimated as follows: buildings, including leasehold improvements, over five to 50 years and machinery and equipment over three to 20 years . Intangible assets with finite useful lives are amortized over their useful lives. We periodically review the recoverability of our property, plant and equipment and intangible assets subject to amortization whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. We recognized impairment losses of $1.2 million, $3.8 million and $4.2 million for property, plant and equipment in 2019, 2018 and 2017, respectively, and $16.7 million for intangible assets with finite lives in 2018. See Note 19 — “Impairment and Restructuring Charges” Revenue Recognition We recognize revenue when control of metal products or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. There are no significant judgments or estimates made to determine the amount or timing of our reported revenues. The amount of transaction price associated with unperformed performance obligations is not significant as of December 31, 2019 and 2018. Metal Sales We have minimal long-term contract sales with our customers as we primarily transact in the spot market under fixed price sales orders. The majority of our metal product sales orders generally have only one performance obligation: sale of processed or unprocessed metal product. Control of the metal products we sell transfers to our customers upon delivery for orders with FOB destination terms or upon shipment for orders with FOB shipping point terms. Shipping and handling charges to our customers are included in net sales. We account for all shipping and handling of our products as fulfillment activities and not as a promised good or service. Costs incurred in connection with the shipping and handling of our products are typically included in operating expenses whether we use a third-party carrier or our own trucks. In 2019, 2018 and 2017, shipping and handling costs included in Warehouse, delivery, selling, general and administrative expenses were $404.1 million, $412.7 million and $372.3 million, respectively. Shipment and delivery of our orders generally occur on the same day due to the close proximity of our customers and our metals service center locations. Toll Processing and Logistics Toll processing services relate to the processing of customer-owned metal. Logistics services primarily include transportation services for metal we toll-process. Revenue for these services is recognized over time as the toll processing or logistics services are performed. The toll processing services are generally short-term in nature with the service being performed in less than one day . Seasonality Some of our customers are in seasonal businesses, especially customers in the construction industry and related businesses. However, our overall operations have not shown any material seasonal trends as a result of our geographic, product and customer diversity. Typically, revenues in the months of July, November and December have been lower than in other months because of a reduced number of working days for shipments of our products, resulting from holidays observed by the Company as well as vacation and extended holiday closures at some of our customers. Stock-Based Compensation All of our stock-based compensation plans are considered equity plans. The fair value of stock awards and restricted stock units is determined based on the fair value of our common stock on the grant date. The fair value of stock awards and restricted stock units is expensed on a straight-line basis over their respective vesting periods, net of forfeitures when they occur. Stock-based compensation expense was $51.2 million, $45.5 million and $33.4 million in 2019, 2018 and 2017, respectively, and is included in the Warehouse, delivery, selling, general and administrative expense caption of our consolidated statements of income. Environmental Remediation Costs We accrue for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remediation feasibility study. Such accruals are adjusted as further information develops or circumstances change. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable. We are not aware of any environmental remediation obligations that would materially affect our operations, financial position or cash flows. See Note 16 — “Commitments and Contingencies” Income Taxes We file a consolidated U.S. federal income tax return with our wholly owned domestic subsidiaries. Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax reporting bases of assets and liabilities using the enacted tax rates expected to be in effect when such differences are realized or settled. The effect on deferred taxes from a change in tax rates is recognized in income in the period that includes the enactment date of the change. The provision for income taxes reflects the taxes to be paid for the period and the change during the period in the deferred tax assets and liabilities. We evaluate on a quarterly basis whether, based on all available evidence, it is probable that the deferred income tax assets are realizable. Valuation allowances are established when it is estimated that it is more likely than not that the tax benefit of the deferred tax asset will not be realized. We make a comprehensive review of our uncertain tax positions on a quarterly basis. Tax benefits are recognized when it is more likely than not that a tax position will be sustained upon examination by the authorities. The benefit from a position that has surpassed the more-likely-than-not threshold is the largest amount of benefit that is more than 50% likely to be realized upon settlement. We recognize interest and penalties accrued related to unrecognized tax benefits as a component of income tax expense. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Reform”) was enacted, which included significant changes to the taxation of U.S. corporations. These changes include, among other things, a reduction of the U.S. federal statutory rate from 35% to 21% effective in 2018, the implementation of a territorial tax system, a one-time tax in 2017 on accumulated foreign profits that have not been previously subject to U.S. tax law (transition tax), the repeal of the corporate alternative minimum tax and changes to business deductions, including a new limitation on the deductibility of business interest, stricter limits on the deductibility of certain executive compensation and the repeal of the deduction for domestic production activities. For further discussion of the impact of the tax legislation, see Note 11 — “Income Taxes.” Foreign Currencies The currency effects of translating the financial statements of our foreign subsidiaries, which operate in local currency environments, are included in other comprehensive income (loss). Gains and losses resulting from foreign currency transactions are included in the results of operations in the Other (income) expense, net caption and amounted to net losses of $4.1 million in 2019, net gains of $0.6 million in 2018 and net losses of $4.9 million in 2017. Impact of Recently Issued Accounting Standards—Adopted Leases a lease liability using a modified retrospective transition method and provide enhanced disclosures. In July 2018, the FASB issued an update to these accounting changes providing an additional, optional transition method that allows lessees the option to initially apply the new accounting changes at the adoption date while continuing to present all prior periods under previous lease accounting guidance. We adopted the new standard on January 1, 2019 using the optional transition method and available practical expedients. The practical expedients allow us, among other things, to carry forward our assessment of lease classification and remaining lease terms under the previous lease accounting guidance. Our adoption of the new lease standard resulted in the recognition of $186.3 million of operating lease right-of-use assets and $187.1 million of operating lease liabilities but did not have a material impact on our consolidated statements of income, equity or cash flows. For further discussion of our leases, see Note 10 – “Leases.” Impact of Recently Issued Accounting Standards—Not Yet Adopted Income Taxes Financial Instruments – Credit Losses |
