Property, Plant and Equipment [Abstract]

5.	PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment is recorded net of accumulated depreciation of $8.46 billion at July 1, 2017 ($8.16 billion at December 31, 2016).

Given the natural gas pricing environment, Nucor performed an impairment assessment of its proved producing natural gas well assets in December 2016. One of the main assumptions that most significantly affects the undiscounted cash flows 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, in conjunction with a review of projections by numerous sources of market data. This analysis was performed on each of Nucor’s three groups of wells, with each group defined by common geographic location. Each of Nucor’s three groups of wells passed the impairment test. One of the groups of wells had estimated undiscounted cash flows that were noticeably closer to its carrying value of $80.8 million as of December 31, 2016. The carrying value of that group of wells was $75.8 million at July 1, 2017. Changes in the natural gas industry or a prolonged low price environment beyond what had already been assumed in the analysis could cause management to revise the natural gas price assumptions, which could possibly result in an impairment of some or all of the groups of proved well assets.
