Goodwill and Intangible Assets Disclosure [Abstract] |
GOODWILL | GOODWILL Goodwill is recognized when the consideration paid for a business exceeds the fair value of the tangible and identifiable intangible assets acquired. Goodwill is allocated to reporting units for purposes of testing goodwill for impairment. We test goodwill for impairment on an annual basis or more frequently if events or circumstances change in a manner that would more likely than not reduce the fair value of a reporting unit below its carrying value. There were no charges for goodwill impairment in the six-month periods ended June 30, 2024 and 2023. Accumulated goodwill impairment losses amount to $303.6 million ($252.7 million in our former Cement segment and $50.9 million in our Concrete segment). Changes in the carrying amount of goodwill by reportable segment from December 31, 2023 to June 30, 2024 are shown below:
in millions | Aggregates | Asphalt | Concrete | Total
Goodwill at December 31, 2023 | $ | 3,330.2 |  | $ | 91.6 |  | $ | 109.9 |  | $ | 3,531.7 |
