Nucor Corporation – Notes to Condensed Consolidated Financial Statements (Unaudited)

Reclassifications – In the first quarter of 2018, the Company began reporting its tubular products and piling products businesses as part of the steel products segment. These businesses were previously included in the steel mills segment and were reclassified to the steel products segment as part of a realignment of Nucor’s reportable segments to reflect the way in which they are now viewed by management and how segment performance assessments will be made by the chief operating decision maker beginning in such period. As a result, certain prior period amounts have been reclassified to conform to the current year presentation. These reclassifications did not have an impact on the condensed consolidated financial statements of the Company for the prior periods presented. See Note 15 for more information related to this segment realignment.

Recently Adopted Accounting Pronouncements – In the first quarter of 2018, we adopted new accounting guidance related to revenue recognition for all contracts using the modified retrospective method. The modified retrospective method requires that the cumulative effect of initially applying this new guidance be recorded as an adjustment to the opening balance of retained earnings in the condensed consolidated balance sheet. The adoption of this new accounting guidance did not have an impact on any prior period earnings attributable to Nucor stockholders, and no adjustment was recorded to the opening retained earnings balance as of January 1, 2018. Retrospective adjustment of comparative prior period information is not required when using the modified retrospective adoption method, and no comparative prior periods have been adjusted for the new guidance.

The adoption of the new revenue accounting guidance did not significantly change the way we recognize revenue. To illustrate this, if we had continued using the previous accounting guidance in effect before the adoption of the new revenue accounting guidance, our consolidated net sales for the secondthird quarter and first sixnine months of 2018 would have increased approximately $22.7$25.2 million, or 0.4%, and $32.9$58.1 million, or 0.3%, respectively, and cost of products sold would have increased by the same amounts. There would have been no impact on any other financial statement line items in the condensed consolidated financial statements for the secondthird quarter or first sixnine months of 2018. See Note 16 for disclosures required by the new revenue accounting guidance.

In the first quarter of 2018, we adopted new accounting guidance regarding the recognition and measurement of financial assets and financial liabilities. Changes to the current accounting guidance primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the Financial Accounting Standards Board clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses onavailable-for-sale debt securities. The accounting for other financial instruments, such as loans, investments in debt securities and financial liabilities, is largely unchanged. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements.

In the first quarter of 2018, we adopted new accounting guidance regarding the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. The new guidance addresses specific cash flow presentation issues in order to reduce diversity in existing practice. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements.

In the first quarter of 2018, we adopted new accounting guidance regarding intra-entity transfers of assets other than inventory. The new guidance requires that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The adoption of this new guidance did not have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements -Pronouncements—In February 2016, new accounting guidance was issued regarding the accounting for leases. The new guidance requires all lessees to recognize on the balance sheet right to use assets and lease liabilities for the rights and obligations created by lease arrangements with terms greater than 12 months. The new guidance is effective for the Company for annual and interim reporting periods beginning after December 15, 2018. In July 2018, this accounting guidance was amended to permit companies to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption and to continue reporting comparative periods prior to adoption in accordance with current lease guidance. The Company will adopt this new guidance in the first quarter of 2019 and will record a cumulative adjustment to the January 1, 2019 retained earnings balance. While the adoption of this new guidance is expected to increase assets and liabilities due to the recognition of lease rights and obligations on the Company’s consolidated balance sheet effective January 1, 2019, the Company does not expect the adoption of this new guidance to have a significant impact on its consolidated statement of earnings, statement of comprehensive income or statement of cash flows.

In February 2018, new accounting guidance was issued regarding the tax effects of the Tax Cuts and Jobs Act (the “Tax Reform Act”). The new guidance allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Reform Act to improve the usefulness of information reported to financial statement users. The new guidance is effective for the Company for annual and interim reporting periods beginning after December 15, 2018. The Company does not expect the adoption of this new guidance to have a material impact on its consolidated financial statements.

Given the natural gas pricing environment,In September 2018, Nucor performed an impairment assessmentanalysis of its proved producing natural gas well assets due to the current and projected natural gas pricing environment at our sales point in December 2017.the Piceance Basin, which continued to deteriorate during 2018. Management has monitored these assets since the last impairment analysis was performed in the fourth quarter of 2017, and the deterioration in the current and projected natural gas pricing and, in particular, the projected natural gas pricing at our sales point in the Piceance Basin reached such a level in the third quarter of 2018 that management determined that a triggering event had occurred. One of the main assumptions that most significantly affects the undiscounted cash flowsflow determination is management’s estimate of future natural gas prices. The pricing used in this impairment assessment was developed by management based on projected natural gas market supply and demand dynamics. Management also makes key estimates on the expected reserve levels and on the expected drilling production costs. Thisdynamics, in conjunction with a review of projections by market analysts. The impairment analysis was performed on each of Nucor’s three groups (“fields”) of wells, with each groupfield defined by common geographic location. Each

Two of Nucor’s three groupsfields of wells passeddid not pass the undiscounted cash flow impairment test.analysis. Anafter-tax discounted cash flow analysis was performed for these two fields to determine the amount of impairment. The carrying values of these two fields were impaired by a combined $110.0 million. The impairment charge is included in impairment of assets in the condensed consolidated statements of earnings for the three months (13 weeks) and nine months (39 weeks) ended September 29, 2018. The post-impairment combined carrying value of the three groups of wellsthese two fields was $241.0$72.4 million at June 30, 2018 ($252.0September 29, 2018. The third field was not impaired and has a current carrying value of $53.3 million at December 31, 2017).September 29, 2018. Changes in the natural gas industry or a continuation of theprolonged low price environment beyond what had already beenwas assumed in thethis most recent analysis could cause management to revise the natural gas price assumptions, the estimated reserves or the estimated drilling production costs. Unfavorable revisions to these assumptions or estimatescosts, all of which could possibly result in anfuture impairment of some or all of the groups ofthese proved well assets.

Previously, Nucor’s tubular products and piling products businesses were reported in the steel mills segment. Beginning in the first quarter of 2018, these businesses were reclassified to the steel products segment to better reflect the way in which they are viewed by management.

Nucor completed its most recent annual goodwill impairment testing during the fourth quarter of 2017 and concluded that as of such time there was no impairment of goodwill for any of its reporting units. There have been no triggering events requiring an interim assessment for impairment since the most recent annual goodwill impairment testing date.

Nucor’s investment in Duferdofin Nucor at June 30,September 29, 2018 was $275.2$272.2 million ($285.9 million at December 31, 2017). Nucor’s 50% share of the total net assets of Duferdofin Nucor was $114.5$113.6 million at June 30,September 29, 2018, resulting in a basis difference of $160.7$158.6 million due to thestep-up to fair value of certain assets and liabilities attributable to Duferdofin Nucor as well as the identification of goodwill ($89.889.5 million) and finite-lived intangible assets. This basis difference, excluding the portion attributable to goodwill, is being amortized based on the remaining estimated useful lives of the various underlying net assets, as appropriate. Amortization expense associated with the fair valuestep-up was $2.3 million and $2.2 million in the secondthird quarter of 2018 and 2017, respectively, and was $4.8$7.1 million and $4.3$6.6 million in the first sixnine months of 2018 and 2017, respectively.

As of June 30,September 29, 2018, Nucor had outstanding notes receivable of €35.0 million ($40.840.6 million) from Duferdofin Nucor (€35.0 million, or $41.9 million, as of December 31, 2017).

Fair value measurements for Nucor’s cash equivalents and short-term investments are classified under Level 1 because such measurements are based on quoted market prices in active markets for identical assets. Fair value measurements for Nucor’s derivatives, which are typically commodity or foreign exchange contracts, are classified under Level 2 because such measurements are based on published market prices for similar assets or are estimated based on observable inputs such as interest rates, yield curves, credit risks, spot and future commodity prices and spot and future exchange rates.

The fair value of short-term and long-term debt, including current maturities, was approximately $4.53$4.48 billion at June 30,September 29, 2018 ($4.19 billion at December 31, 2017). The debt fair value estimates are classified under Level 2 because such estimates are based on readily available market prices of our debt at June 30,September 29, 2018 and December 31, 2017, or similar debt with the same maturities, ratings and interest rates.

We are from time to time a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. With respect to all such lawsuits, claims and proceedings, we record reserves when it is probable a liability has been incurred and the amount of loss can be reasonably estimated. We do not believe that any of these proceedings, individually or in the aggregate, would be expected to have a material adverse effect on our results of operations, financial position or cash flows. Nucor maintains liability insurance with self-insurance limits for certain risks.

The Company also maintains a number of inactive plans under which stock-based awards remain outstanding but no further awards may be made. As of June 30,September 29, 2018, 2.01.9 million shares were reserved for issuance upon the future settlement of outstanding awards under such inactive plans.

Stock Options– Stock options may be granted to Nucor’s key employees, officers andnon-employee directors with exercise prices at 100% of the market value on the date of the grant. The stock options granted are generally exercisable at the end of three years and have a term of 10 years. New shares are issued upon exercise of stock options.

Board of Directors after satisfying age and years of service requirements. RSUs granted to anon-employee director are fully vested on the grant date and are payable to thenon-employee director in the form of common stock after the termination of the director’s service on the Board of Directors.

RSUs granted to employees who are eligible for retirement on the date of grant are expensed immediately, and RSUs granted to employees who will become retirement-eligible prior to the end of the vesting term are expensed over the period through which the employee will become retirement-eligible since these awards vest upon retirement from the Company. Compensation expense for RSUs granted to employees who will not become retirement-eligible prior to the end of the vesting term is recognized on a straight-line basis over the vesting period.

Cash dividend equivalents are paid to holders of RSUs each quarter. Dividend equivalents paid on RSUs expected to vest are recognized as a reduction in retained earnings.

The fair value of an RSU is determined based on the closing price of Nucor’s common stock on the date of the grant.grant. A summary of Nucor’s RSU activity for the first sixnine months of 2018 is as follows (shares in thousands):

Compensation expense for RSUs was $32.6$8.5 million and $21.1$6.1 million in the secondthird quarter of 2018 and 2017, respectively, and $38.3$46.8 million and $26.1$32.2 million in the first sixnine months of 2018 and 2017, respectively. As of June 30,September 29, 2018, unrecognized compensation expense related to unvested RSUs was $62.1$53.9 million, which is expected to be recognized over a weighted-average period of 2.12.0 years.

A summary of Nucor’s restricted stock activity under the AIP and the LTIP for the first sixnine months of 2018 is as follows (shares in thousands):

Compensation expense for common stock and common stock units awarded under the AIP and the LTIP is recorded over the performance measurement and vesting periods based on the anticipated number and market value of shares of common stock and common stock units to be awarded. Compensation expense for anticipated awards based upon Nucor’s financial performance, exclusive of amounts payable in cash, was $5.3$4.9 million and $3.2$3.6 million in the secondthird quarter of 2018 and 2017, respectively, and $9.7$14.6 million and $7.5$11.1 million in the first sixnine months of 2018 and 2017, respectively.

In the third quarter of 2018, upon completion of its 2017 federal tax return, Nucor finalized the analysis of the previously estimatedone-time transition tax. Nucor included a transition tax expense of $2.4 million in the third quarter of 2018, which had a 0.3% impact on the third quarter effective tax rate. While we do not anticipate any remaining adjustments related to the Tax Reform Act, the measurement period under SAB 118 remains open due to anticipated further guidance clarifying certain aspects of the Tax Reform Act. Any subsequent adjustment to these amounts will be recorded to current tax expense in the fourth quarter of 2018 when the full analysis is complete.

The effective tax rate for the secondthird quarter of 2018 was 21.9%23.4% compared to 32.7%28.2% for the secondthird quarter of 2017. The decrease in the effective tax rate for the secondthird quarter of 2018 as compared to the secondthird quarter of 2017 was primarily due to the permanent lowering of the U.S. corporate federal income tax rate from 35% to 21% effective for the years beginning after December 31, 2017 under the Tax Reform Act. This decrease was somewhat offset by increases in the effective tax rate due to the elimination of the domestic manufacturing deduction under the Tax Reform Act. The third quarter of 2017 included a net tax benefit totaling $13.2 million related to a return to provision change in estimate and state tax credits.

Nucor has concluded U.S. federal income tax matters for years through 2013. The tax years 2014 through 20162017 remain open to examination by the Internal Revenue Service. The Canada Revenue Agency has substantially concluded its examination of the 2012 and 2013 Canadian returns for Harris Steel Group Inc. and certain related affiliates. The tax years 20102011 through 2017 remain open to examination by other major taxing jurisdictions to which Nucor is subject (primarily Canada and other state and local jurisdictions).

Non-current deferred tax assets included in other assets in the condensed consolidated balance sheets were $0.7$0.8 million at June 30,September 29, 2018 ($0.6 million at December 31, 2017).Non-current deferred tax liabilities included in deferred credits and other liabilities in the condensed consolidated balance sheets were $376.6$382.7 million at June 30,September 29, 2018 ($329.3 million at December 31, 2017).
