The annual assessment performed in 2021 for one of the Company’s reporting units, Rebar Fabrication, used forward-looking projections in future cash flows. The fair value of this reporting unit exceeded its carrying value by approximately 54% in the most recent assessment. If our assessment of the relevant facts and circumstances changes, including if the expected future performance of this reporting unit declines from the most recent assessment, non-cash impairment charges may be required. Total goodwill associated with the Rebar Fabrication reporting unit was $350.0 million as of October 1, 2022 ($363.0 million as of December 31, 2021). An impairment of goodwill may also lead us to record an impairment of other intangible assets. Total finite-lived intangible assets associated with the Rebar Fabrication reporting unit were $38.1 million as of October 1, 2022 ($45.0 million as of December 31, 2021). There have been no triggering events requiring an interim assessment for impairment of the Rebar Fabrication reporting unit since the most recent annual goodwill impairment testing date. Intangible assets with estimated useful lives of five to 25 years are amortized on a straight-line or accelerated basis and were comprised of the following as of October 1, 2022 and December 31, 2021 (in thousands): October 1, 2022 December 31, 2021 Gross Amount Accumulated Amortization Gross Amount Accumulated Amortization Customer relationships $ 4,174,901 $ 1,035,901 $ 1,872,348 $ 924,506 Trademarks and trade names 364,140 126,781 217,255 99,906 Other 109,746 93,164 105,522 66,954 $ 4,648,787 $ 1,255,846 $ 2,195,125 $ 1,091,366 Intangible asset amortization expense in the third quarter of 2022 and 2021 was $77.2 million and $34.8 million, respectively, and $164.5 million and $76.7 million in the first nine months of 2022 and 2021, respectively

The Internal Revenue Service (the “IRS”) is currently examining Nucor’s 2015, 2019 and 2020 federal income tax returns. Nucor has concluded U.S. federal income tax matters for tax years through 2014, and for tax years 2016 and 2018. The tax years 2017 and 2021 remain open to examination by the IRS. The 2015 and 2018 Canadian income tax returns for Harris Steel Group Inc. and certain related affiliates are currently under examination by the Canada Revenue Agency. The tax years 2016 through 2021 remain open to examination by other major taxing jurisdictions to which Nucor is subject (primarily Canada and other state and local jurisdictions).

Business Combinations [Abstract]
Acquisitions	18. Acquisitions Acquisition of C.H.I. On June 24, 2022, Nucor used cash on hand to acquire the assets of C.H.I. for a purchase price, net of cash acquired, of billion. C.H.I. is a leading manufacturer of overhead doors for residential and commercial markets in the United States and Canada. Commercial overhead doors are used in warehousing and retail, areas that Nucor has focused its attention on recently through other value-added products such as insulated metal panels (CENTRIA, Metl-Span and TrueCore brands) and steel racking solutions (Nucor Warehouse Systems). It is expected that the C.H.I. acquisition also will benefit from Nucor’s recent paint line investments at its Hickman, Arkansas and Crawfordsville, Indiana sheet mills. The C.H.I. business financial results are included as part of the steel products segment (see Note 14) We allocated the purchase price for C.H.I. to its individual assets acquired and liabilities assumed. While the purchase price allocation is substantially complete, it is still preliminary and subject to change, including for the final working capital settlement. The following table summarizes the fair values of the assets acquired and liabilities assumed of C.H.I. as of June 24, 2022, the date of acquisition (in thousands): Cash $ 159,066 Accounts receivable 73,549 Inventory 52,515 Other current assets 19,493 Property, plant and equipment 117,392 Goodwill 1,036,332 Other intangible assets 2,389,180 Other assets 9,559 Total assets acquired 3,857,086 Current liabilities 75,146 Deferred income taxes 579,559 Other liabilities 7,509 Total liabilities assumed 662,214 Net assets acquired $ 3,194,872 The following table summarizes the purchase price allocation to the identifiable intangible assets of C.H.I. as of June 24, 2022, the date of acquisition (in thousands, except years): Weighted- Average Life Customer relationships $ 2,242,000 25 years Trade name 147,000 13 years $ 2,389,000 The goodwill of $1.04 billion is calculated as the excess of the purchase price over the fair values of the assets acquired and liabilities assumed and has been allocated to the steel products segment (see Note 4). The goodwill is attributable to expected synergies within the steel products segment. Goodwill recognized for tax purposes was $5.6 million, all of which is deductible for tax purposes. Acquisition of CSI On February 1, 2022, Nucor used cash on hand to acquire a 51% controlling ownership position in CSI by purchasing a 50% equity interest from a subsidiary of Vale S.A. for a cash purchase price of approximately $400.0 million, adjusted for net debt and working capital at closing, as well as a 1% equity interest from JFE Steel Corporation. CSI is a flat-rolled steel converter with the capability to produce more than two million tons of finished steel and steel products annually. The company has five product lines, including hot rolled, pickled and oiled, cold rolled, galvanized and electric resistance welded (“ERW”) pipe. Key end-use markets served by CSI include customers in the construction, service center and energy industries. We believe this acquisition helps give Nucor a strong presence in the Western region of the United States and grows our ability to produce a wide range of value-added sheet products. The CSI business financial results were included as part of the steel mills segment (see Note 14) beginning on February 1, 2022, the date Nucor acquired its 51% controlling ownership position. We allocated the purchase price for CSI to its individual assets acquired and liabilities assumed. While the purchase price allocation is substantially complete, it is still preliminary and subject to change. The following table summarizes the fair values of 100% of the assets and liabilities of CSI, as well as the fair value of the 49% noncontrolling interest not acquired by Nucor, as of February 1, 2022, the date Nucor acquired its (in thousands): Cash $ 98,537 Accounts receivable 159,257 Inventory 354,614 Other current assets 5,298 Property, plant and equipment 566,714 Goodwill 62,011 Other intangible assets — Other assets 7,071 Total assets acquired 1,253,502 Current portion of long-term debt 9,826 Other current liabilities 162,808 Long-term debt due after one year 67,866 Other liabilities 139,947 Total liabilities assumed 380,447 Net assets acquired at 100% 873,055 Less: Fair value of noncontrolling interest 427,797 Net assets acquired at 51% $ 445,258 The determination of the fair value of the noncontrolling interest was calculated using the implied value of 100% of the enterprise value of the business using the purchase price as the purchase price did not include a control premium on a per-share basis and the noncontrolling interest shareholder will participate equally in the economic benefits of CSI after the acquisition. The goodwill of $62.0 million is calculated as the excess of the purchase price over the fair values of the assets acquired and liabilities assumed and has been allocated to the steel mills segment (see Note 4). The goodwill is attributable to the assembled workforce acquired, expanding our Western United States presence and CSI’s value-added product capabilities. None of the goodwill is deductible for tax purposes. The results of operations for CSI upon the effective date of the acquisition have been included in the accompanying financial statements. Pro-forma results of operations for the Company would not be materially different as a result of the acquisition of CSI and, therefore, this information is not presented. Other Acquisitions Other smaller acquisitions in the first nine months of 2022, exclusive of purchase price adjustments made and net of cash acquired, totaled approximately $160.1 million. Pro-forma results of operations for the Company would not be materially different if the aggregate acquisitions made during the first nine months of 2022 were included and, therefore, this information is not presented.
