The 2017 amount reflects $19.4 million of gains on the sale of assets, primarily excess land, offset by $12.7 million of nonrecurring repair costs related to certain of the Company’s leased railcars and $10.8 million of executive retirement expense. The asset and portfolio rationalization charge relates to the Company’s Southwest ready mixed concrete operations reported in the West Group. This charge reflects the Company’s evaluation of the recoverability of certain long-lived assets, including property, plant and equipment and intangible assets, for underperforming operations in this business and a reduction in workforce. Of the total charge, $17.0 million was noncash and $1.8 million was settled in cash.
