Revenue From Contract With Customer [Abstract] |
Revenue | 23. Revenue Revenue is recognized when obligations under the terms of contracts with our customers are satisfied; generally, this occurs upon shipment or when control is transferred. Revenue is measured as the amount of consideration expected to be received in exchange for transferring the goods. In addition, revenue is deferred when cash payments are received or due in advance of performance. The durations of Nucor’s contracts with customers are generally one year or less. Customer payment terms are generally 30 days. Contract liabilities are primarily related to deferred revenue resulting from cash payments received in advance from customers to protect against credit risk. Contract liabilities totaled $120.2 million as of December 31, 2020 ($108.6 million as of December 31, 2019), and are included in accrued expenses and other current liabilities in the consolidated balance sheets. The amount of revenue reclassified from the December 31, 2019 contract liabilities balance during 2020 was approximately $80.5 million. Nucor disaggregates its revenues by major source in the same manner as presented in the net sales by product table in the segment footnote (see Note 22). Steel Mills Segment Sheet – For the majority of sheet products, we transfer control and recognize a sale when we ship the product from the sheet mill to our customer. The amount of consideration we receive and revenue we recognize for spot market sales are based upon prevailing prices at the time of sale. The amount of consideration we receive and revenue we recognize for contract customers are based primarily on pricing formulas that incorporate monthly or quarterly price adjustments which reflect changes in the current market-based indices and/or raw material costs near the time of shipment. The amount of tons sold to contract customers at any given time depends on a variety of factors, including our consideration of current and future market conditions, our strategy to appropriately balance spot and contract tons in a manner to meet our customers’ requirements while considering the expected profitability, our desire to sustain a diversified customer base and our end-use customers’ perceptions about future market conditions. These contracts are typically one year or less. Contract sales within the steel mills segment are most notable in our sheet operations, as it is common for contract sales to account for the majority of sheet sales in a given year. Bar, Structural and Plate – For the majority of bar, structural and plate products, we transfer control and recognize a sale when we ship the product from the mill to our customer. The significant majority of bar, structural and plate product sales are spot market sales, and the amount of consideration we receive and revenue we recognize for those sales are based upon prevailing prices at the time of sale. Steel Products Segment Tubular Products – The tubular products businesses transfer control and recognize a sale when the products are shipped from our operating locations to our customers. The significant majority of tubular product sales are spot market sales, and the amount of consideration we receive and revenue we recognize for those sales are based upon prevailing prices at the time of sale. Rebar Fabrication – The majority of revenue relates to revenue from contracts with customers for the supply of fabricated rebar. As the majority of contracts with customers are fixed price contracts to complete a job, control transfers over time and revenue is recognized (if collection is reasonably assured) over time using an input method, based on the amount of rebar shipped from the Company’s operating locations relative to the total expected amount of rebar required to complete the job. For contracts to supply fabricated rebar and install it at the customer’s job site, there are two performance obligations: (1) the supply of the fabricated rebar and (2) the installation of the supplied rebar at the customer’s job site. For the supply of fabricated rebar performance obligation, the transaction price allocated to this performance obligation is determined at the start of the contract, based on the awarded contract price for the supplied fabricated rebar and revenue is recognized over time based on the amount of rebar shipped from the Company’s operating locations relative to the total expected amount of rebar required to complete the job. For the installation of supplied rebar performance obligation, the transaction price allocated to this performance obligation is determined at the start of the contract, based on the awarded contract price for the installation of fabricated rebar and revenue is recognized over time based on the amount of rebar installed relative to the total expected amount of rebar required to be installed to complete the job. While a majority of the contracts with customers are fixed price contracts to complete a job, variable consideration can occur from contract modifications relating to change orders and price escalations caused by changes in underlying material costs. In these situations, the additional variable consideration is recognized cumulatively in the period in which the contract modification is approved, and collection is reasonably assured unless the change order relates to additional distinct goods or services at standalone selling prices in which case they are accounted for prospectively. Management reviews these situations on a case-by-case basis and considers a variety of factors, including relevant experience with similar types of performance obligations, the Company’s experience with the customer and collectability considerations. Other Steel Products – Other steel products include our joist, deck, cold finish, metal building systems, piling and the other remaining businesses that comprise the steel products segment. Generally, for these businesses, we transfer control and recognize a sale when we ship the product from our operating locations to our customers. The amount of consideration we receive and revenue we recognize for those sales are agreed upon with the customers before the product is shipped. Raw Materials Segment The majority of the raw materials segment revenue from outside customers is generated by The David J. Joseph Company and its affiliates. We transfer control and recognize a sale based on the terms of the agreement with the customer, which is generally when the product has met the delivery requirements. The amount of consideration we receive and revenue we recognize for those sales is based on the contract with the customer, which generally reflects current market prices at the time the contract is entered into.
