Business Combination and Asset Acquisition [Abstract] |
Acquisitions and disposals | Acquisitions and disposals In March 2021, the Company completed the acquisition of the Structural Composites Industries LLC ("SCI") business of Worthington Industries, Inc., based in Pomona, California, for $19.3 million cash consideration. The fair value of assets and liabilities acquired were equal to the cash consideration paid. There were acquisition-related costs of $0.3 million and $1.5 million in 2022 and 2021 respectively. These represented transitional costs and professional fees incurred in relation to the above SCI acquisition. In 2021, the Company recognized a net gain on disposition of $6.6 million, consisting of a $7.1 million gain on our U.S. aluminum business, sold in March 2021, partially offset by a $0.5 million loss on our Superform U.K. business sold in September 2021.
