Organization, Consolidation and Presentation of Financial Statements [Abstract]

Reclassifications

Reclassifications – In the first quarter of 2018, the Company began reporting its tubular products and piling businesses as part of the steel products segment. These businesses were previously included in the steel mills segment. 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 and cash flows of the Company for the prior period presented. See Note 15 for more information related to this segment realignment.

Recently Adopted Accounting Pronouncements

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 first quarter of 2018 would have increased approximately $10.2 million, or 0.2%, and cost of products sold would have increased by the same amount. There would have been no impact on any other financial statement line items in the condensed consolidated financial statements for the first quarter 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 on available-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

Recently Issued Accounting 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. The Company is evaluating the impact that the adoption of this new guidance will have on its consolidated financial statements, but the Company expects that assets and liabilities will increase on its consolidated balance sheet.
