Note 7. Goodwill and Intangible Assets 

The Company has recognized goodwill and certain intangible assets in connection with prior business combinations. The Company performed a qualitative test as of the annual impairment testing date of August 31, 2024 and 2023, in which there were no impairment indicators present. The Company performed a quantitative impairment analysis as of August 31, 2022. Based on the results of this analysis the fair values of the Company's reporting units were in excess of their carrying values and as such, no impairments were identified.

The valuation methodology used to value the trade names during the quantitative impairment analysis as of August 31, 2022, was based on the relief-from-royalty method which is an income-based measure that derives the value from total revenue growth projected and what percentage is attributable to the trade names. As a result of the analysis, the Company identified that the fair value of its Brundage-Bone Concrete Pumping, Eco-Pan and Capital Pumping trade names exceeded their carrying values by approximately 61%, 49% and 127%, respectively, and their remaining values are $37.3 million, $7.7 million and $5.5 million as of October 31, 2022, respectively.

The goodwill impairment test performed as of August 31, 2022, was performed on the Company’s U.S. Concrete Pumping, U.S. Concrete Waste Management Services, and U.K. Operations reporting units. The valuation methodologies used to value the reporting units included the discounted cash flow method (income approach) and the guideline public company method (market approach). As a result of the goodwill impairment analysis, the Company identified that the fair values of its U.S. Concrete Pumping, U.S. Concrete Waste Management Services and U.K. Operations reporting units were approximately 7%, 82% and 32% greater than their carrying values, respectively. As such, no impairment charge was recorded. If the planned business performance expectations are not met or if specific valuation factors out of our control, such as the discount rate, change significantly, then the estimated fair values of the reporting unit might decline and lead to a goodwill impairment in the future.

The following table summarizes the composition of intangible assets as of October 31, 2024 and 2023:

Amortization expense for the year ended  October 31, 2024 and 2023 was $15.1 million and $18.9 million, respectively. Based on intangible asset values and currency exchange rates as of  October 31, 2024, total intangible asset amortization expense is expected to be $11.8 million, $9.5 million, $7.8 million, $6.5 million, and $5.1 million for years ending October 31, 2025 through 2029, respectively, and approximately $14.4 million combined for all years thereafter.

The changes in the carrying value of goodwill by reportable segment for the years ended October 31, 2024 and 2023 are as follows:

Goodwill in the above table is presented net of accumulated impairment losses of $52.9 million as of October 31, 2024 and 2023. The U.S. Concrete Pumping and U.K. Operations reportable segments recorded $38.5 million and $14.4 million, respectively, in accumulated impairment losses.
