Inventories

Inventory Disclosure [Abstract]
Inventories	NOTE 4: INVENTORIES The Company primarily uses the last-in, first-out (LIFO) method of valuing inventory. In the first quarter of 2022, we changed the method we use to estimate LIFO on an interim basis. This is a change in accounting estimate that is inseparable from a change in accounting principle. Historically, interim LIFO calculations were based on actual inventory levels and costs at each interim period. In the first quarter of 2022, we elected to recognize the interim effects of the LIFO inventory valuation method by projecting expected year-end inventory levels and LIFO costs and allocating that projection to the interim quarters on a pro-rata basis. The change in the LIFO calculation method impacts all profit-based metrics as well as inventories for interim periods. Our annual LIFO calculation will be consistent with prior years and as such, year-end amounts will not be impacted. We believe this change is preferable as it results in a better estimate of LIFO for the full year, creates less volatility in earnings on an interim basis, and makes our results more comparable to our peers. LIFO expense was $2.2 million for the quarter ended March 31, 2022 compared to $83.8 million during the quarter ended March 31, 2021. LIFO expense for the quarter ended March 31, 2021 as compared to the quarter ended March 31, 2022 is higher due to a significant increase in metal prices, which occurred in the quarter ended March 31, 2021 as compared to pricing changes forecasted for December 2022. Inventories, at stated LIFO value, were classified at March 31, 2022 and December 31, 2021 as follows: March 31, December 31, 2022 2021 (In millions) In process and finished products $ 839.1 $ 832.1 If current cost had been used to value inventories, such inventories would have been $305 million and $303 million higher than reported at March 31, 2022 and December 31, 2021, respectively. Approximately 88% of inventories are accounted for under the LIFO method at March 31, 2022 and December 31, 2021. Non-LIFO inventories consist primarily of inventory at our foreign facilities using the moving average cost and the specific cost methods. Substantially all of our inventories consist of finished products. The Company has consignment inventory at certain customer locations, which totaled $8.6 million and $8.8 million at March 31, 2022 and December 31, 2021, respectively.

This fourth amendment also added the ability to convert up to $100 million of commitments under the Ryerson Credit Facility into a “first-in, last-out” sub-facility (the “FILO Facility”). Subject to certain limitations, such conversion can be made from time to time (but no more than twice in the aggregate) prior to the date that is two years after November 5, 2020. At March 31, 2022 , Ryerson of outstanding of letters of credit issued, available under Amounts outstanding under the Ryerson Credit Facility bear interest at (i) a rate determined by reference to (A) the base rate (the highest of the Federal Funds Rate plus 0.50%, Bank of America, N.A.’s prime rate, and the one-month LIBOR rate plus 1.00%, however, in no event shall the base rate be less than 1.25%), or (B) a LIBOR rate (with a floor of 0.25%) or, (ii) for Ryerson Holding’s Canadian subsidiary that is a borrower, (A) a rate determined by reference to the Canadian base rate (the greatest of the Federal Funds Rate plus 0.50%, Bank of America-Canada Branch’s “base rate” for commercial loans in U.S. Dollars made at its “base rate”, and the 30 day LIBOR rate plus 1.00%), (B) the prime rate (the greater of Bank of America-Canada Branch’s “prime rate” for commercial loans made by it in Canada in Canadian Dollars and the one-month Canadian bankers’ acceptance rate (with a floor of 0.25%) plus 1.00%, or (C) the bankers’ acceptance rate, however, in no event shall the Canadian base rate or the Canadian prime rate be less than 1.25%). Through November 5, 2021 the spread over the base rate and prime rate was fixed at 0.50% and the spread over the LIBOR for the bankers’ acceptances was fixed at 1.50%. After November 5, 2021, the spread over the base rate and prime rate is between 0.25% and 0.50% and the spread over the LIBOR for the bankers’ acceptances is between 1.25% and 1.50%, depending on the amount available to be borrowed under the Ryerson Credit Facility. The spread with respect to the FILO Facility, if any, will be determined at the time the commitments under the Ryerson Credit Facility are converted into such FILO Facility. Ryerson also pays commitment fees on amounts not borrowed at a rate of 0.225%. Overdue amounts and all amounts owed during the existence of a default bear interest at 2.00% above the rate otherwise applicable thereto. Loans advanced under the FILO Facility may only be prepaid if all then outstanding revolving loans are repaid in full. LIBOR rates will stop being published on June 30, 2023, at that time the interest rate on the Ryerson Credit Facility will be replaced by the Secured Overnight Financing Rate (“SOFR”). We attempt to minimize interest rate risk exposure through the utilization of interest rate swaps, which are derivative financial instruments. In June 2019, we entered into an interest rate swap to fix interest on $60 million of our floating rate debt under the Ryerson Credit Facility at a rate of 1.729% through June 2022. In November 2019, we entered into another interest rate swap to fix interest on $100 million of our floating rate debt under the Ryerson Credit Facility at a rate of 1.539% through November 2022 2.5 Borrowings under the Ryerson The Ryerson Ryerson Ryerson The Ryerson Ryerson Ryerson The lenders under the Ryerson Ryerson Net repayments of short-term borrowings that are reflected in the Condensed Consolidated Statements of Cash Flows represent borrowings under the Ryerson 2028 Notes On July 22, 2020, JT Ryerson issued $500 million in aggregate principal amount of its 2028 Senior Secured Notes (“2028 Notes”). The 2028 Notes bear interest at a rate of 8.50% per annum. The 2028 Notes are fully and unconditionally guaranteed on a senior secured basis by all of our existing and future domestic subsidiaries that are co-borrowers or that have guarantee obligations under the Ryerson Credit Facility. The 2028 Notes and the related guarantees are secured by a first-priority security interest in substantially all of JT Ryerson’s and each guarantor’s present and future assets located in the U.S. (other than receivables, inventory, cash deposit accounts and certain other assets, and proceeds thereof, which are secured pursuant to a second-priority security interest), subject to certain exceptions and customary permitted liens. The 2028 Notes will be redeemable, in whole or in part, at any time on or after August 1, 2023 at certain redemption prices. The redemption price for the 2028 Notes if redeemed during the twelve months beginning (i) August 1, 2023 is 104.250%, (ii) August 1, 2024 is 102.125%, and (iii) August 1, 2025 and thereafter is 100.000%. All redemption amounts also include accrued and unpaid interest, if any, to, but not including, the redemption date. JT Ryerson may also redeem some or all of the 2028 Notes before August 1, 2023 at a redemption price of 100.000% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the redemption date, plus a “make-whole” premium. In addition, JT Ryerson may redeem up to 40% of the outstanding 2028 Notes before August 1, 2023 with the net cash proceeds from certain equity offerings at a price equal to 108.500% of the principal amount of the Notes, plus accrued but unpaid interest, if any, to, but not including, the redemption date. Furthermore, JT Ryerson may redeem the 2028 Notes at any time and from time to time prior to August 1, 2023 in an aggregate principal amount equal to up to 10% of the original aggregate principal amount of the 2028 Notes during each twelve month period commencing on July 22, 2020 at a redemption price of 103.000%, plus accrued and unpaid interest, if any, to, but not including, the redemption date. JT Ryerson may also redeem the 2028 Notes at any time prior to August 1, 2022 in an aggregate principal amount equal to $100.0 million on a one-time basis from the net cash proceeds received from the sale of real property, at a redemption price of 104.000% plus accrued and unpaid interest, if any, to, but not including, the redemption date. The Company completed partial redemptions of $200 million utilizing these redemption options between the fourth quarter of 2020 and fourth quarter 2021, resulting in an outstanding balance of $300 million as of December 31, 2021. In addition, JT Ryerson may be required to make an offer to purchase the 2028 Notes upon the sale of certain assets or upon a change of control. The Company evaluated the redemption options within the 2028 Notes for embedded derivatives and determined that one redemption option required bifurcation as it is not clearly and closely related to the debt agreement. The Company determined the fair value of the embedded derivative as of December 31, 2021 was $0.2 million which was recorded within other current assets in the Condensed Consolidated Balance Sheet. As of March 31, 2022, the fair value was determined to be zero with the change of $0.2 million recognized within other income and (expense), net on the Condensed Consolidated Statements of Comprehensive Income. Refer to Note 10: Derivatives and Fair Value Measurements for further discussion of the embedded derivative. The 2028 Notes contain customary covenants that, among other things, limit, subject to certain exceptions, our ability, and the ability of our restricted subsidiaries, to incur additional indebtedness, pay dividends on our capital stock or repurchase our capital stock, make investments, sell assets, engage in acquisitions, mergers, or consolidations, or create liens or use assets as security in other transactions. During the first three months of 2022, a principal amount of $63.1 million of the 2028 Notes were repurchased for $68.4 million and retired, resulting in the recognition of a $5.3 million loss within other income and (expense), net on the Condensed Consolidated Statement of Comprehensive Income. As a result, $236.9 million in aggregate principal amount of the 2028 Notes remain outstanding at March 31, 2022. Foreign Debt At March 31, 2022, Ryerson China’s foreign borrowings were $22.9 million, which were owed to banks in Asia at a weighted average interest rate of 3.4% per annum and secured by inventory and property, plant, and equipment. At December 31, 2021, Ryerson China’s foreign borrowings were $27.0 million rate of 3.6% Availability under the foreign credit lines was $24 million and $20 million at March 31, 2022 and December 31, 2021, respectively. Letters of credit issued by our foreign subsidiaries were $5 million and $6 million at March 31, 2022 and December 31, 2021, respectively.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 9: COMMITMENTS AND CONTINGENCIES In October 2011, the United States Environmental Protection Agency (the “EPA”) named JT Ryerson as one of more than 100 businesses that may be a potentially responsible party (“PRP”) for the Portland Harbor Superfund Site (the “PHS Site”). On January 6, 2017, the EPA issued an initial Record of Decision (“ROD”) regarding the site. The ROD includes a combination of dredging, capping, and enhanced natural recovery that would take approximately thirteen years to construct plus additional time for monitored natural recovery, at an estimated present value cost of $1.05 billion. At a December 4, 2018 meeting with the Portland Harbor Participation and Common Interest Group (“PCI Group”), of which JT Ryerson is a member, the EPA indicated that it expected PRPs to submit a plan during 2019 to start remediation of the river and harbor per the ROD within the next two to three years. The EPA also indicated that it expected allocation of amounts among the parties to be determined in the same two to three-year The EPA met with various PRPs throughout 2019 and 2020 regarding remedial design. The EPA did not include JT Ryerson in those meetings. It did include Schnitzer Steel, which is developing a remedial design plan for the river area which includes the area where the former JT Ryerson facilities were located. Schnitzer Steel’s 2020 disclosures filed with the EPA acknowledged that Schnitzer Steel is the legal successor to the prior operators (including JT Ryerson) in the designated area. On February 12, 2021, the EPA announced that one hundred percent (100%) of the PHS Site is now in the active remedial design phase. In June 2021, the EPA issued a Fact Sheet setting forth the status of the entire site. The primary area of relevance for JT Ryerson is River Mile 3.5 East, with Swan Island Basin being of secondary interest. For River Mile 3.5, remedial design work is ongoing; the Sufficiency Assessment and the Pre-Design Investigation work plans are finalized, and design investigation sampling is underway. Schnitzer Steel and MMGL Corp. are the working parties for River Mile 3.5. For Swan Island, remedial design is just beginning, with Daimler Trucks, Shipyard Commerce, and various government entities as the working parties. JT Ryerson has not been asked to participate in the remedial design phase. The PCI Group has engaged a third party to prepare cost estimates for each of the Sediment Management Areas at the site. That work is still in progress and is expected to be completed in 2022. In the meantime, the voting parties of the PCI Group (which does not include JT Ryerson) have begun the “advocacy process,” during which the voting parties submit written arguments to the Allocation Team regarding how costs should be allocated among the various PRPs. This process is anticipated to be completed sometime in 2022 or early 2023. Once the advocacy process is completed, the Allocation Team will prepare a proposed allocation of costs among the PRPs. All PRPs, including JT Ryerson, will then participate in the “mediation process,” during which the PRPs will attempt to agree on a final cost allocation. The mediation process is currently anticipated to occur sometime in late 2022 or 2023. The EPA has stated that it is willing to consider de minimis settlements, which JT Ryerson is trying to pursue; however, the EPA has not begun meeting with any of the smaller parties who have requested de minimis or de micromis status, stating that it does not have sufficient information to determine whether any parties meet such criteria and does not intend to begin those considerations until after the remedial design work is completed. It has met with selected parties that we believe to be larger targets. JT Ryerson has not been invited to meet with the EPA. As a result of the ongoing negotiations and filings over the ROD and the EPA’s decision not to meet with smaller parties, we cannot determine how allocations will be made and whether a de minimus settlement can be reached with the EPA. As the EPA has not yet allocated responsibility for the contamination among the potentially responsible parties, including JT Ryerson, we do not currently have sufficient information available to us to determine whether the ROD will be executed as currently stated, whether and to what extent JT Ryerson may be held responsible for any of the identified contamination, and how much (if any) of the final plan’s costs might ultimately be allocated to JT Ryerson. Therefore, management cannot predict the ultimate outcome of this matter or estimate a range of potential loss at this time. There are various other claims and pending actions against the Company. The amount of liability, if any, for those claims and actions at March 31, 2022 is not determinable but, in the opinion of management, such liability, if any, will not have a material adverse effect on the Company’s financial position, results of operations, or cash flows. We maintain liability insurance coverage to assist in protecting our assets from losses arising from or related to activities associated with business operations.

Derivatives and Fair Value Measurements	NOTE 10: DERIVATIVES AND FAIR VALUE MEASUREMENTS Derivatives The Company may use derivatives to partially offset its business exposure to commodity price, foreign currency, and interest rate fluctuations and their related impact on expected future cash flows and certain existing assets and liabilities. However, the Company may choose not to hedge certain exposures for a variety of reasons including, but not limited to, Company policy, accounting considerations, or the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in commodity pricing, foreign currency exchange, or interest rates. Interest rate swaps are entered into to manage interest rate risk associated with the Company’s floating-rate borrowings. We use foreign currency exchange contracts to hedge variability in cash flows in our Canada, Mexico, and China operations when a payment currency is different from our functional currency. From time to time, we may enter into fixed price sales contracts with our customers for certain of our inventory components. We may enter into metal commodity futures and options contracts to reduce volatility in the price of these metals. We may also enter into fixed price natural gas contracts and diesel fuel derivative contracts to manage the price risk of forecasted purchases of natural gas and diesel fuel. We have two receive variable, pay fixed, interest rate swaps to manage the exposure to variable interest rates of the Ryerson Credit Facility. In June 2019, we entered into a forward agreement for $60 million of “pay fixed” interest at 1.729% through June 2022 and in November 2019, we entered into a forward agreement for $100 million of “pay fixed” interest at 1.539% through November 2022. Upon entering into the swaps, the interest rate reset dates and critical terms matched the terms of our existing debt and anticipated critical terms of future debt under the Ryerson Credit Facility The Company currently does not account for its commodity and foreign exchange derivative contracts as hedges but rather marks them to market with a corresponding offset to current earnings. The Company regularly reviews the creditworthiness of its derivative counterparties and does not expect to incur a significant loss from the failure of any counterparties to perform under any agreements. In connection with the redemption options under the 2028 Notes, the Company recorded an embedded derivative in other current assets on its Condensed Consolidated Balance Sheet, with changes in value recorded within other income and (expense), net within the Condensed Consolidated Statement of Comprehensive Income, see Note 7: Long-term debt, for further details. Embedded derivatives are separated from the host contract and carried at fair value when: (a) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract; (b) the instrument is not measured at fair value under other applicable GAAP standards, and (c) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument. The Company has concluded that the embedded derivative within the 2028 Notes met these criteria and, as such, must be valued separate and apart from the 2028 Notes at fair value each reporting period. The following table summarizes the location and fair value amount of our derivative instruments reported in our Condensed Consolidated Balance Sheets as of March 31, 2022 and December 31, 2021: Asset Derivatives Liability Derivatives Balance Sheet Location March 31, 2022 December 31, 2021 Balance Sheet Location March 31, 2022 December 31, 2021 Derivatives not designated as hedging instruments under ASC 815 (In millions) Metal commodity contracts Prepaid expenses and other current assets $ 20.4 $ 13.0 Other accrued liabilities $ 33.1 $ 35.1 Diesel fuel commodity contracts Prepaid expenses and other current assets 0.7 — Other accrued liabilities — — 2028 Notes embedded derivative Prepaid expenses and other current assets — 0.2 Other accrued liabilities — — Interest rate swaps Prepaid expenses and other current assets — — Other accrued liabilities 0.3 1.4 Total derivatives $ 21.1 $ 13.2 $ 33.4 $ 36.5 The following table presents the volume of the Company’s activity in derivative instruments as of March 31, 2022 and December 31, 2021: Notional Amount Derivative Instruments At March 31, 2022 At December 31, 2021 Unit of Measurement Hot roll coil swap contracts 152,076 176,859 Tons Aluminum swap contracts 15,396 20,949 Tons Nickel swap contracts 534 857 Tons Diesel fuel swap contracts 700,000 840,000 Gallons Foreign currency exchange contracts 3.5 million 4.5 million U.S. dollars Interest rate swap contracts 160 million 160 million U.S. dollars The following table summarizes the location and amount of gains and losses on derivatives not designated as hedging instruments reported in our Condensed Consolidated Statements of Comprehensive Income for the three months ended March 31, 2022 and 2021: Derivatives not designated as Location of Gain/(Loss) Amount of Gain/(Loss) Recognized in Income on Derivatives Amount of Gain/(Loss) Reclassified from Other Comprehensive Income into Income hedging instruments Recognized in Income Three Months Ended March 31, Three Months Ended March 31, under ASC 815 on Derivatives 2022 2021 2022 2021 (In millions) Metal commodity contracts Cost of materials sold $ (2.6 ) $ (10.7 ) $ — $ — Diesel fuel commodity contracts Warehousing, delivery, selling, general, and administrative 0.7 — — — 2028 Notes embedded derivative Other income and (expense), net (0.2 ) 0.3 — — Foreign exchange contracts Other income and (expense), net — 0.1 — — Interest rate swaps Interest and other expense on debt 0.6 — (0.7 ) (0.5 ) Total $ (1.5 ) $ (10.3 ) $ (0.7 ) $ (0.5 ) As of March 31, 2022, the portion of the interest rate swap fair value that would be reclassified into earnings during the next 12 months as interest expense is approximately $1.2 million. Fair Value Measurements To increase consistency and comparability in fair value measurements, FASB ASC 820 “ Fair Value Measurement 1. Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date. 2. Level 2 – inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. 3. Level 3 – unobservable inputs, such as internally-developed pricing models for the asset or liability due to little or no market activity for the asset or liability. The following table presents assets and liabilities measured and recorded at fair value on our Condensed Consolidated Balance Sheet on a recurring basis and their level within the fair value hierarchy as of March 31, 2022: At March 31, 2022 Level 1 Level 2 Level 3 (In millions) Assets Derivatives: Derivatives not designated as hedging instruments under ASC 815: Metal commodity contracts $ — $ 20.4 $ — Diesel fuel commodity contracts — 0.7 — Total derivatives $ — $ 21.1 $ — Liabilities Derivatives: Derivatives not designated as hedging instruments under ASC 815: Metal commodity contracts $ — $ 33.1 $ — Interest rate swaps — 0.3 — Total derivatives $ — $ 33.4 $ — The following table presents assets and liabilities measured and recorded at fair value on our Condensed Consolidated Balance Sheet on a recurring basis and their level within the fair value hierarchy as of December 31, 2021: At December 31, 2021 Level 1 Level 2 Level 3 (In millions) Assets Derivatives: Derivatives not designated as hedging instruments under ASC 815: Metal commodity contracts $ — $ 13.0 $ — 2028 Notes embedded derivative — — 0.2 Total derivatives $ — $ 13.0 $ 0.2 Liabilities Derivatives: Derivatives not designated as hedging instruments under ASC 815: Metal commodity contracts $ — $ 35.1 $ — Interest rate swaps — 1.4 — Total derivatives $ — $ 36.5 $ — The fair value of each commodity, diesel fuel, and swap derivative contract is determined using Level 2 inputs and the market approach valuation technique, as described in ASC 820. The Company has various commodity derivatives to lock in hot roll coil, nickel, aluminum, and diesel fuel prices for varying time periods. The fair value of hot roll coil, nickel, aluminum, and diesel fuel derivatives is determined based on the spot price each individual contract was purchased at and compared with the one-month daily average actual spot price on the Chicago Mercantile Exchange (hot roll coil and diesel fuel) and the London Metals Exchange (nickel and aluminum), respectively, for the commodity on the valuation date. In addition, the Company has numerous foreign exchange contracts to hedge variability in cash flows when a payment currency is different from our functional currency. The Company defines the fair value of foreign exchange contracts as the amount of the difference between the contracted and current market value at the end of the period. The Company estimates the current market value of foreign exchange contracts by obtaining month-end market quotes of foreign exchange rates and forward rates for contracts with similar terms. The Company uses the exchange rates provided by Reuters. Each commodity, diesel fuel, and foreign exchange contract term varies in the number of months, but in general, contracts are between 1 to 12 months in length. The fair value of our interest rate swap is based on the sum of all future net present value cash flows for the fixed and floating leg of the swap. The future cash flows are derived based on the terms of our interest rate swap, as well as published discount factors, and projected forward LIBOR rates. The fair value of the embedded derivative is determined using Level 3 inputs based on the Black-Derman-Toy lattice model and the “with-and-without” approach. This method estimates the value of the 2028 Notes both with and without the embedded derivative. The value of the embedded derivative is the difference between the two methods. The value of the 2028 Notes with the embedded derivative is based on recent trading prices of the 2028 Notes (Level 1 inputs). Determining the value of the 2028 Notes without the embedded derivative requires significant judgements made by management such as the probability of redemption linked transactions occurring, the cash flows expected to be generated from these transactions, as well as the timing of these transactions (Level 3 inputs). The changes in financial instruments measured at fair value for which the Company has used Level 3 inputs to determine fair value are as follows: 2028 Notes Embedded Derivative (In millions) Balance at January 1, 2022 $ 0.2 Unrealized loss recorded in other income and (expense), net (0.2 ) Balance at March 31, 2022 $ — 2028 Notes Embedded Derivative (In millions) Balance at January 1, 2021 $ 2.3 Unrealized gain recorded in other income and (expense), net 0.3 Balance at March 31, 2021 $ 2.6 The carrying and estimated fair values of our financial instruments at March 31, 2022 and December 31, 2021 were as follows: At March 31, 2022 At December 31, 2021 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Cash and cash equivalents $ 44.7 $ 44.7 $ 51.2 $ 51.2 Restricted cash 1.1 1.1 1.2 1.2 Receivables less provisions 778.7 778.7 630.8 630.8 Accounts payable 602.6 602.6 481.2 481.2 Long-term debt, including current portion 551.3 571.3 639.3 666.8 The estimated fair value of the Company’s cash and cash equivalents, restricted cash, receivables less provisions, and accounts payable approximate their carrying amounts due to the short-term nature of these financial instruments. The estimated fair value of the Company’s long-term debt and the current portions thereof is determined by using quoted market prices of Company debt securities (Level 2 inputs).

Stock-Based Compensation	NOTE 11: STOCK-BASED COMPENSATION Under the 2014 Omnibus Incentive Plan (“2014 Plan”), as amended, which is the Company’s only equity compensation plan, we may grant stock options and other equity-based awards, including restricted stock units (“RSUs”) and performance stock units (“PSUs”), to certain employees. Awards that expire or are forfeited without delivery of shares generally become available for future issuance under the plan. As stock options are exercised, and RSUs and PSUs vest, we issue new shares of Ryerson common stock. Each RSU and PSU consists of the right to receive one share of our common stock. RSUs also have dividend equivalent rights equal to the accrued cash dividends where the record date for such dividends is after the grant date but before the shares vest. All rights under RSUs and PSUs are generally forfeited upon employee termination. Stock based compensation expense related to stock options, RSUs, and PSUs was $1.3 million and $1.6 million for the three months ended March 31, 2022 and 2021, respectively. No stock options have been exercised as of March 31, 2022. A summary of the status of our unvested RSUs and PSUs as of March 31, 2022 and changes during the three months then ended is as follows: Shares Weighted Average Grant Date Fair Value Per Unit (In thousands) Restricted Stock Units Unvested at January 1, 2022 317 $ 12.00 Granted 192 35.02 Vested (154 ) 10.56 Unvested at March 31, 2022 355 $ 25.12 Performance Stock Units Unvested at January 1, 2022 684 $ 10.62 Granted 277 35.02 Vested (215 ) 8.56 Unvested at March 31, 2022 746 $ 20.27 Shares reserved for future grants 957 The fair value of the 2022 RSUs and PSUs granted was $35.02 per share, determined by the closing price of our common stock on the grant date. The Company’s RSU awards vest in three separate and equal tranches over a three-year As of February 2022, the Board has approved remitting taxes on behalf of certain employees related to net share settlements of restricted stock units. No tax payments have been made as of March 31, 2022.

Revenue Recognition	NOTE 13: REVENUE RECOGNITION We are a leading value-added processor and distributor of industrial metals with operations in the United States, Canada, Mexico, and China. We purchase large quantities of metal products from primary producers and sell these materials in smaller quantities to a wide variety of metals-consuming industries. Nearly 80% of the metals products sold are processed by us to a specified thickness, length, width, shape, and surface quality pursuant to specific customer orders. Disaggregated Revenue We have one operating and reportable segment, metals service centers. The Company derives substantially all of its sales from the distribution of metals. The following table shows the Company’s percentage of sales by major product line: Three Months Ended March 31, Product Line 2022 2021 Carbon Steel Flat 31 % 29 % Carbon Steel Plate 10 9 Carbon Steel Long 13 14 Stainless Steel Flat 19 17 Stainless Steel Plate 5 5 Stainless Steel Long 4 4 Aluminum Flat 11 14 Aluminum Plate 2 2 Aluminum Long 4 4 Other 1 2 Total 100 % 100 % A significant majority of the Company’s sales are attributable to its U.S. operations.

Payment terms on invoiced amounts are typically 30 days from the invoice date. We do not have any contracts with significant financing components. Receivables, which are included in accounts receivables within the Condensed Consolidated Balance Sheet, from contracts with customers were $791.4 million and $633.0 million as of March 31, 2022 and December 31, 2021, respectively. Contract assets, which consist primarily of revenues recognized over time that have not yet been invoiced and estimates of the value of inventory that will be received in conjunction with product returns changes in the contract assets and the contract liabilities balances during the period are as follows: Contract Assets Contract Liabilities (In millions) Beginning Balance at January 1, 2022 $ 21.3 $ 15.1 Contract liability satisfied during the period — (7.7 ) Contract liability incurred during the period — 8.3 Net change in contract assets and liabilities for products with no alternative use during the period (2.2 ) — Changes to reserves 0.7 1.2 Ending Balance at March 31, 2022 $ 19.8 $ 16.9 The Company’s performance obligations are typically short-term in nature.

Credit Loss [Abstract]
Provision for Credit Losses	NOTE 14: PROVISION FOR CREDIT LOSSES Provisions for allowances and claims on accounts receivables and contract assets are based upon historical rates, expected trends, and estimates of potential returns, allowances, customer discounts, and incentives. The Company considers all available information when assessing the adequacy of the provision for allowances, claims, and doubtful accounts. The Company performs ongoing credit evaluations of customers and sets credit limits based upon review of the customers’ current credit information, payment history, and the current economic and industry environments. The Company’s credit loss reserve consists of two parts: a) a provision for estimated credit losses based on historical experience and b) a reserve for specific customer collection issues that the Company has identified. Estimation of credit losses requires adjusting historical loss experience for current economic conditions and judgments about the probable effects of economic conditions on certain customers. The following table provides a reconciliation of the provision for credit losses reported within the Condensed Consolidated Balance Sheets as of March 31, 2022: Changes in Provision for Expected Credit Losses (In millions) Balance at January 1, 2022 $ 2.2 Current period provision 0.3 Write-offs charged against allowance (0.1 ) Recoveries 0.3 Balance at March 31, 2022 $ 2.7

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 15: INCOME TAXES For the three months ended March 31, 2022, the Company recorded income tax expense of 55.0 As required by ASC 740, the Company assesses the realizability of its deferred tax assets. The Company records a valuation allowance when, based upon the evaluation of all available evidence, it is more-likely-than-not that all or a portion of the deferred tax assets will not be realized. In making this determination, we analyze, among other things, our recent history of earnings, the nature and timing of reversing book-tax temporary differences, tax planning strategies, and future income. The Company maintains a valuation allowance on certain foreign and U.S. federal deferred tax assets until such time as in management’s judgment, considering all available positive and negative evidence, the Company determines that these deferred tax assets are more likely than not realizable. The valuation allowance is reviewed quarterly and will be maintained until sufficient positive evidence exists to support the reversal of some or all of the valuation allowance . The valuation allowance was $5.0 million at both March 31, 2022 and December 31, 2021. The Company accounts for uncertain income tax positions in accordance with ASC 740. We anticipate that certain statutes of limitation will close within the next twelve months resulting in the immaterial reduction of the reserve for uncertain tax benefits related to various intercompany transactions. No changes were recorded in the first quarter of 2022, therefore, the balance of $0.8 million at December 31, 2021 remains unchanged.

In April of 2022, we repurchased $15.2 million outstanding principal of our 2028 Notes for $16.5 million, resulting in the recognition of a loss of $1.3 million within other income (expense) within the Condensed Consolidated Statement of Comprehensive Income in the second quarter of 2022. As a result, we will write off $0.2 million of debt issuance costs in the second quarter 2022 within interest expense in the Condensed Consolidated Statement of Comprehensive Income. Bond Repurchase Authorization. On May 4, 2022, the Company’s Board of Directors approved a bond repurchase program authorizing the Company to repurchase up to $172.0 million of the 2028 Notes, through December 31, 2022. This bond repurchase program is in addition to the Company’s special redemption right to redeem up to $50 million in principal at a redemption price of 103.0% discussed in Note 7: Long Term Debt. Under the bond repurchase program, management is authorized to purchase the 2028 Notes from time to time through open market purchases or privately negotiated transactions, including by making a tender offer to the holders of the Notes, and pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, subject to market conditions and other factors. Dividends. On May 4, 2022, the Board of Directors declared a quarterly cash dividend in the amount of $0.125 per share of common stock, payable on June 16, 2022 to stockholders of record as of June 2, 2022.
