Schedule of Equity Method Investments [Line Items] |
Summary of the Difference Between Carrying Amount and Underlying Equity of Equity Method Investment | Our recorded investment in WAVE was higher than our 50% share of the carrying values reported in WAVE’s consolidated financial statements by $119.3 million as of December 31, 2025 and $123.6 million as of December 31, 2024. These differences arose from our adoption of fresh-start reporting upon our emergence from Chapter 11 of the U.S. Bankruptcy Code in October 2006, while WAVE’s consolidated financial statements do not reflect fresh-start reporting. The differences are composed of the following fair value adjustments to assets:
|  | December 31, 2025 |  |  | December 31, 2024 |
Property, plant and equipment |  | $ | 0.4 |  |  | $ | 0.4 |
Other intangibles |  |  | 88.5 |  |  |  | 92.8 |
Goodwill |  |  | 30.4 |  |  |  | 30.4 |
Total |  | $ | 119.3 |  |  | $ | 123.6 |
