The steel mill operations consist of six electric arc furnace ("EAF") mini mills, three EAF micro mills and one rerolling mill. The steel mills manufacture finished long steel products including reinforcing bar ("rebar"), merchant bar, light structural and other special sections and wire rod, as well as semi-finished billets for rerolling and forging applications (collectively referred to as "steel products" in the context of the North America Steel Group segment). The fabrication operations primarily fabricate rebar and steel fence posts and offer post-tension cable products (collectively referred to as "downstream products" in the context of the North America Steel Group segment). The general strategy in the North America Steel Group segment is to optimize the Company's vertically integrated value chain to maximize profitability by obtaining the lowest possible input costs and highest possible selling prices. The Company operates the recycling facilities to provide low-cost scrap to the steel mills and the fabrication operations to optimize the steel mill volumes. The North America Steel Group segment's products are sold primarily to steel mills and foundries, as well as construction, fabrication and other manufacturing industries. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Europe Steel Group</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Europe Steel Group segment is composed of a vertically integrated network of recycling facilities, an EAF mini mill and fabrication operations located in Poland.

The Company's performance obligations arise from (i) sales of raw materials, steel products, downstream products, construction products and ground stabilization solutions and (ii) installation services performed by its fabrication operations. The shipment of products to customers is considered a fulfillment activity and amounts billed to customers for shipping and freight are included in net sales, and the related costs are included in cost of goods sold.

For contracts where the Company provides fabricated rebar and installation services, revenue is recognized over time using an input measure of progress based on contract costs incurred to date compared to total estimated contract costs ("input measure"). This input measure provides a reasonable depiction of the Company’s progress towards satisfaction of the performance obligation as there is a direct relationship between costs incurred by the Company and the transfer of the fabricated rebar and installation services. Revenue from fabricated rebar contracts where the Company does not provide installation services is recognized over time using an output measure of progress based on tons shipped compared to total estimated tons ("output measure"). This output measure provides a reasonable depiction of the transfer of contract value to the customer, as there is a direct relationship between the units shipped by the Company and the transfer of the fabricated rebar. If total estimated costs on any contract are greater than the net contract revenues, the Company recognizes the entire estimated loss in the period the loss becomes known.

Capitalization of qualifying internal-use software costs begins when the preliminary project stage is completed, management with the relevant authority, implicitly or explicitly, authorizes and commits to funding the project and it is probable that the project will be completed and the software will perform as intended. Costs incurred in the application and infrastructure development phases, including significant enhancements and upgrades, are capitalized. Capitalization ends once a project is substantially complete and the software is ready for its intended purpose.

The Company determines if an arrangement is a lease at inception of a contract if the terms state the Company has the right to direct the use of, and obtain substantially all the economic benefits from, a specific asset identified in the contract. The ROU assets represent the Company's right to use the underlying assets for the lease term, and the lease liabilities represent the obligation to make lease payments arising from the leases. The Company's ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments to be made over the lease term. Certain of the Company's lease agreements contain options to extend the lease. The Company evaluates these options on a lease-by-lease basis, and if the Company determines it is reasonably certain to be exercised, the lease term includes the extension. The Company uses its incremental borrowing rate at lease commencement to determine the present value of lease payments, and lease expense is recognized on a straight-line basis over the lease term. The incremental borrowing rate is the rate of interest the Company could borrow on a collateralized basis over a similar term with similar payments.

The Company accounts for grants related to assets by deducting the grant in arriving at the carrying amount of the asset on the consolidated balance sheets. Non-monetary grants are recognized at fair value. The Company recognizes the grant in profit or loss over the life of the depreciable asset as a reduction to depreciation expense. Grants related to non-depreciable assets may require the fulfillment of certain obligations and, in such cases, would be recognized in profit or loss over the periods that bear the cost of meeting the obligations.

The purpose of the PCSA in each year was to provide aid to energy-intensive companies to offset indirect costs of rising carbon emission rights included in energy costs. The amount of government assistance awarded by the PCSA in each year was dependent upon the Company meeting certain electricity consumption thresholds and the number of other applicants.

To evaluate goodwill and other indefinite-lived intangible assets for impairment, the Company may use qualitative assessments to determine whether it is more likely than not that the fair value of a reporting unit, including goodwill, or an indefinite-lived intangible asset is less than its carrying amount. The qualitative assessments consider multiple factors, including the current operating environment, historical and future financial performance and industry and market conditions. If an initial qualitative assessment identifies that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is performed.

When performing a quantitative impairment test, the Company estimates the fair value of its reporting units using a weighting of fair values derived from the income and market approaches. Under the income approach, the Company determines the fair value of a reporting unit based on the present value of estimated future cash flows. Cash flow projections are based on management's estimates of revenue growth rates and operating margins, taking into account industry and market conditions. The discount rate is based on a weighted average cost of capital adjusted for the relevant risk associated with the characteristics of the reporting unit. The market approach estimates fair value based on market multiples of earnings derived from comparable publicly traded companies with similar operating and investment characteristics as the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is indicated in the amount that the carrying value exceeds the fair value of the reporting unit, not to exceed the goodwill value for the reporting unit. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">When estimating the fair value of indefinite-lived intangible assets using a quantitative approach, the Company uses an income approach to calculate the fair value of the indefinite-lived intangible assets using a relief from royalty method.

Costs incurred in the application and infrastructure development phases, including significant enhancements and upgrades, are capitalized.

If the CCA does not include a software license, the service element of the arrangement is accounted for as a service contract. The Company defers certain implementation costs for its CCAs that are service contracts, which are included in prepaids and other current assets and other noncurrent assets in the Company's consolidated balance sheets.
