Basis of Presentation
Basis of Presentation	1. Basis of Presentation 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, all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation with respect to the interim financial statements, have been included. The results of operations for the nine months ended September 30, 2018 are not necessarily indicative of the results for the full year ending December 31, 2018. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto for the year ended December 31, 2017, 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. 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.

Impact of Recently Issued Accou

Impact of Recently Issued Accounting Guidance
Impact of Recently Issued Accounting Guidance	2. Impact of Recently Issued Accounting Guidance Impact of Recently Issued Accounting Standards—Adopted Revenue from Contracts with Customers —In May 2014, the Financial Accounting Standards Board (“FASB”) issued accounting changes that replaced most of the detailed guidance on revenue recognition that previously existed under U.S. GAAP. Under the new standard, an entity should recognize revenue when goods or services are transferred to the customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. We adopted these changes as of January 1, 2018 using the modified retrospective method. See Note 4—“Revenues” for further details. Classification of Certain Cash Receipts and Cash Payments —In August 2016, the FASB issued accounting changes that clarify the presentation and classification of certain cash receipts and payments in the statement of cash flows with the objective of reducing the existing diversity in practice with respect to eight types of cash flows. We adopted these changes as of January 1, 2018. The adoption of this standard did not have a material impact on our consolidated financial statements. Impact of Recently Issued Accounting Standards—Not Yet Adopted Leases — In February 2016, the FASB issued accounting changes that require lessees to recognize most long-term leases on the balance sheet through the recognition of a right-of-use asset and a lease liability using a modified retrospective transition method. 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 and recognize a cumulative-effect adjustment to beginning retained earnings while continuing to present all prior periods under previous lease accounting guidance . The guidance will be effective for fiscal years and interim periods beginning after December 15, 2018, or January 1, 2019 for the Company. Early adoption is permitted. We have implemented a lease management system and are updating our accounting policies and internal controls that would be impacted by the new guidance. We anticipate adopting this new standard on January 1, 2019 using the optional transition method and the available practical expedients. We expect the adoption of these accounting changes will materially increase our assets and liabilities, but will not have a material impact on our net income, stockholders’ equity, or cash flows. We are unable to quantify the ultimate impact of adopting this new standard at this time as the actual impact will depend on the total amount of our lease commitments as of the adoption date. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income — In February 2018, the FASB issued accounting changes that allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (“Tax Reform”) . The guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period. The adoption of this standard will not have a material impact on our consolidated financial statements.

Acquisitions
Acquisitions	3. Acquisitions On August 1, 2018, we acquired KMS Fab, LLC and KMS South, Inc. (collectively, “KMS” or the “KMS Companies”). The KMS Companies are headquartered in Luzerne, Pennsylvania. The KMS Companies specialize in precision sheet metal fabrication ranging from prototypes to large production runs which utilize a wide variety of metals and fabrication methods including laser cutting, stamping, turret punching, machining, powder coating and welding. KMS’ net sales during the period from August 1, 2018 to September 30, 2018 were $4.6 million. On March 1, 2018, we acquired DuBose National Energy Services, Inc. (“DuBose Energy”) and its affiliate, DuBose National Energy Fasteners & Machined Parts, Inc. (“DuBose Fasteners” and, together with DuBose Energy, “DuBose”). DuBose is headquartered in Clinton, North Carolina. DuBose specializes in fabrication, supply and distribution of metal and metal products to the nuclear industry, including utilities, component manufacturers and contractors. DuBose’s net sales during the period from March 1, 2018 to September 30, 2018 were $16.4 million. On October 2, 2017, through our wholly owned subsidiary Diamond Manufacturing Company, we acquired Ferguson Perforating Company (“Ferguson”). Ferguson, headquartered in Providence, Rhode Island, specializes in manufacturing highly engineered and complex perforated metal parts for diverse end markets including industrial machinery, automotive, aerospace, sugar products and consumer electronics manufacturers. Ferguson’s net sales were $29.5 million for the nine months ended September 30, 2018. We funded our 2018 and 2017 acquisitions with borrowings on our revolving credit facility and cash on hand. The acquisitions discussed in this note have been accounted for under the acquisition method of accounting and, accordingly, the respective purchase price has been allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of each acquisition. The accompanying consolidated statements of income include the revenues and expenses of each acquisition since its respective acquisition date. The consolidated balance sheets reflect the allocation of each acquisition’s purchase price as of September 30, 2018 and December 31, 2017, as applicable. The purchase price allocations for our acquisitions of KMS and DuBose are preliminary and are pending the completion of various pre-acquisition period income tax returns. The measurement periods for purchase price allocations do not exceed 12 months from the acquisition date.

Revenues	4. Revenues Revenue from Contracts with Customers On January 1, 2018, we adopted new accounting guidance relating to the recognition of revenue from contracts with our customers using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. We did not record a cumulative-effect adjustment to retained earnings upon adoption and comparable period financial statement amounts have not been adjusted. Our reported results for the nine months ended September 30, 2018 would not have been different if reported under the previous accounting standard. 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 and the amount of our contract balances is not significant. The following table presents our sales disaggregated by product and service. Certain sales taxes or value-added taxes collected from customers are excluded from our reported 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. 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. These 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.

A total of $10.0 million was allocated to the trade names acquired, which is not subject to amortization. We recognized amortization expense for intangible assets of $35.1 million and $38.9 million for the nine months ended September 30, 2018 and 2017, respectively. Foreign currency translation losses related to intangible assets, net, were $1.5 million during the nine months ended September 30, 2018. During the three-month and nine-month periods ended September 30, 2018 we recognized impairment losses of $16.5 million and $16.7 million on our trade name and customer relationship intangible assets, respectively, related to one of our energy businesses. See Note 12—“Impairment and Restructuring Charges” for further discussion of our impairment losses.

Weighted average interest rates on borrowings outstanding on the revolving credit facility were 3.54% and 2.96% as of September 30, 2018 and December 31, 2017, respectively. Weighted average interest rates on borrowings outstanding on the term loan were 3.49% and 2.82% as of September 30, 2018 and December 31, 2017, respectively. Senior Unsecured Notes On November 20, 2006, we entered into an indenture (the “2006 Indenture”), for the issuance of $600.0 million of unsecured debt securities. The total debt issued was comprised of two tranches, (a) $350.0 million aggregate principal amount of senior unsecured notes bearing interest at the rate of 6.20% per annum, which matured and were repaid on November 15, 2016 and (b) $250.0 million aggregate principal amount of senior unsecured notes bearing interest at the rate of 6.85% per annum, maturing on November 15, 2036. On April 12, 2013, we entered into an indenture (the “2013 Indenture” and, together with the 2006 Indenture, the “Indentures”), for the issuance of $500.0 million aggregate principal amount of senior unsecured notes at the rate of 4.50% per annum, maturing on April 15, 2023. Under the Indentures, the notes are senior unsecured obligations and rank equally in right of payment with all of our existing and future unsecured and unsubordinated obligations. If we experience a change in control accompanied by a downgrade in our credit rating, we will be required to repurchase the notes at a price equal to 101% of their principal amount plus accrued and unpaid interest. Other Notes and Revolving Credit Facilities Revolving credit facilities with a combined credit limit of approximately $62.1 million are in place for operations in Asia and Europe with combined outstanding balances of $28.5 million and $53.9 million as of September 30, 2018 and December 31, 2017, respectively. Various industrial revenue bonds had combined outstanding balances of $9.8 million as of September 30, 2018 and $10.1 million as of December 31, 2017, and have maturities through 2027. Covenants The Credit Agreement and the Indentures include customary representations, warranties, covenants, acceleration, indemnity and events of default provisions. The covenants under the Credit Agreement include, among other things, two financial maintenance covenants that require us to comply with a minimum interest coverage ratio and a maximum leverage ratio.

Income Taxes
Income Taxes	8. Income Taxes Our effective income tax rates for the three-month periods ended September 30, 2018 and 2017 were 22.9% and 30.4%, respectively. Our effective income tax rates for the nine-month periods ended September 30, 2018 and 2017 were 23.7% and 31.5%, respectively. Our 2018 three-month and nine-month period effective income tax rates were favorably impacted by the Tax Cuts and Jobs Act of 2017 (“Tax Reform”), which included significant changes to the taxation of U.S. corporations, including a reduction of the U.S. federal statutory rate from 35% to 21%, effective January 1, 2018. Based on our preliminary assessment of the impact of Tax Reform, we recognized a one-time, provisional net tax benefit of $207.3 million in the fourth quarter of 2017, primarily related to the remeasurement of deferred tax assets and liabilities at the lowered federal statutory tax rate, which was partially offset by repatriation and related liabilities . Given the substantial changes to the Internal Revenue Code as a result of Tax Reform, our estimates of the financial impacts attributable to Tax Reform are subject to continuing analysis, interpretation and clarification of the new law, which could result in changes to our estimates in the fourth quarter of 2018. The adjustments to our provisional estimates during the nine months ended September 30, 2018 were not significant. State income taxes offset by the effects of company-owned life insurance policies mainly accounted for the difference between our effective income tax rate and the federal statutory rate for the nine months ended September 30, 2018 .

On October 23, 2018, our Board of Directors amended our share repurchase plan, increasing the total authorized number of shares available to be repurchased by 5.0 million and extending the duration of the plan through December 31, 2021. As of October 23, 2018, we had authorization under the plan to repurchase approximately 10.7 million shares, or about 15% of our current outstanding shares. We repurchase shares through open market purchases under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). During the nine months ended September 30, 2018, we repurchased 1,510,916 shares of our common stock at an average cost of $86.48 per share for a total of $130.7 million. Repurchased and subsequently retired shares are restored to the status of authorized but unissued shares . Common stock and additional paid-in capital activity included the following: Three Months Ended Nine Months Ended September 30, 2018 September 30, 2018 Weighted Average Weighted Average Shares Amount Exercise Price Per Share Shares Amount Exercise Price Per Share (in millions, except share and per share amounts) Stock-based compensation (1) 3,984 $ 14.4 288,991 $ 28.3 Stock options exercised — — 48,275 2.8 $ Share repurchases (2) (918,352) (80.7) (1,510,916) (130.7) Total (914,368) $ (66.3) (1,173,650) $ (99.6) (1) The nine months ended September 30, 2018 amount is comprised of stock-based compensation expense of $33.8 million reduced by $5.5 million of payments we made to tax authorities on our employees’ behalf for shares withheld related to net share settlements. (2) Includes 7,231 shares for $0.6 million pending settlement at September 30, 2018. Dividends On October 23, 2018, our Board of Directors declared the 2018 fourth quarter cash dividend of $0.50 per share. The dividend is payable on December 7, 2018 to stockholders of record as of November 16, 2018. During the third quarters of 2018 and 2017, we declared and paid quarterly dividends of $0.50 and $0.45 per share, or $35.9 million and $32.8 million in total, respectively. During the nine months ended September 30, 2018 and 2017, we declared and paid quarterly dividends of $1.50 and $1.35 per share, or $108.5 million and $98.4 million in total, respectively. During the nine months ended September 30, 2018 and 2017, we paid $2.0 million and $0.9 million in dividend equivalents with respect to vested restricted stock units (“RSUs”), respectively. Stock-Based Compensation We make annual grants of long-term incentive awards to officers and key employees in the forms of service-based and performance-based RSUs that generally have approximately 3-year vesting periods. The performance-based RSU awards are subject to both service and performance goal criteria. We also make annual grants of stock to the non-employee members of the Board of Directors that include dividend rights and vest immediately upon grant. The fair value of the RSUs and stock grants is determined based on the closing stock price of our common stock on the grant date. A summary of the status of our unvested service-based and performance-based RSUs as of September 30, 2018 and changes during the nine-month period then ended is as follows: Weighted Average Grant Unvested Shares Shares Date Fair Value Unvested at January 1, 2018 924,575 $ Granted (1) 474,715 Vested (7,790) Cancelled or forfeited (20,160) Unvested at September 30, 2018 $ Shares reserved for future grants (all plans) (1) 474,715 RSUs, including 178,970 performance-based RSUs, were granted in March 2018.

Commitments and Contingencies.
Commitments and Contingencies	10. Commitments and Contingencies Environmental Contingencies We are currently involved with an environmental remediation project related to activities at former manufacturing operations of Earle M. Jorgensen Company (“EMJ”), our wholly owned subsidiary, that were sold many years prior to our acquisition of EMJ in 2006. Although the potential cleanup costs could be significant, EMJ maintained insurance policies during the time it owned the manufacturing operations that have covered costs incurred to date, and are expected to continue to cover the majority of the related costs. We do not expect that this obligation will have a material adverse impact on our consolidated financial position, results of operations or cash flows. Legal Matters From time to time, we are named as a defendant in legal actions. Generally, these actions arise in the ordinary course of business. We are not currently a party to any pending legal proceedings other than routine litigation incidental to the business. We expect that these matters will be resolved without having a material adverse effect on our results of operations, financial condition or cash flows. We maintain general liability insurance against risks arising out of our normal course of business.

The 2018 charges mainly related to our decision to downsize one of our energy businesses due to changes in competitive factors for certain of the products they sell. The measurement of these assets at fair value was determined using a combination of discounted cash flow techniques for intangible assets and the market approach for property, plant, and equipment.
