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.

During the third quarter of 2022, we recorded an interim goodwill impairment loss of $50.9 million related to the fourth quarter sale of a reporting unit comprised of concrete operations in New Jersey, New York and Pennsylvania (see Note 16). There were no charges for goodwill impairment in the three-month periods ended March 31, 2023 and 2022. Accumulated goodwill impairment losses amount to $303.6 million ($252.7 million in our former Cement segment and $50.9 in our Concrete segment).

We have four reportable segments organized around our principal product lines: Aggregates, Asphalt, Concrete and Calcium. Changes in the carrying amount of goodwill by reportable segment from December 31, 2022 to March 31, 2023 are shown below:
