The asset and portfolio rationalization charge relates to the Company’s Southwest ready mixed concrete operations reported in the West Group reportable segment. 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.
