The following table sets forth the changes in the carrying amount of goodwill for the years ended December 31, 2024, and 2023:


	(in thousands)
Balance as of December 31, 2022 (1)	$	3,456,854
Acquisitions		99,702
Balance as of December 31, 2023 (1)	$	3,556,556
Acquisitions		121,948
Balance as of December 31, 2024 (1)	$	3,678,504

(1) Goodwill is presented net of accumulated impairment losses of $44.6 million.

The change in the carrying amount of goodwill during 2024 is attributable to acquisitions. The amount allocated to goodwill is attributable to the assembled workforces acquired, expected synergies, and expected growth from the new markets which the Company has entered. The goodwill recognized from the TRSMI business combination will not be deductible for tax purposes. The $121.2 million of goodwill recognized from the other current year acquisitions is expected to be deductible and amortized ratably over a 15-year period for tax purposes.

We closely monitor trends in economic factors and their effects on operating results to determine if an impairment trigger was present that would warrant a reassessment of the recoverability of the carrying amount of goodwill prior to the required annual impairment test in accordance with the Intangibles – Goodwill and Other topic of the Codification.

In evaluating goodwill for impairment, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. If it is concluded that it is more likely than not that the fair value of the reporting unit is not less than its carrying value, then no further testing of the goodwill is required. However, if we determine that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, we perform a quantitative goodwill impairment test. This test identifies both the existence of and the amount of goodwill impairment by comparing the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount goodwill is not impaired. If the carrying amount of a reporting unit exceeds its fair value an impairment loss is recognized in an amount equal to that excess, limited to the amount of goodwill allocated to that reporting unit.

The process of evaluating goodwill for impairment involves the determination of the fair value of our reporting units. Our reporting units are aligned with our three geographic operating segments. Inherent in such fair value determinations are certain judgments and estimates relating to future cash flows, including our interpretation of current economic indicators and market valuations and assumptions about our strategic plans with regard to our operations. Due to the uncertainties associated with such estimates, actual results could differ from such estimates resulting in further impairment of goodwill.

In evaluating goodwill for impairment at December 31, 2024, we developed the fair value using a discounted cash flow methodology. The discounted cash flow methodology establishes fair value by estimating the present value of the projected future cash flows to be generated from the reporting unit. The discount rate applied to the projected future cash flows to arrive at the present value is intended to reflect all risks of ownership and the associated risks of realizing the stream of projected future cash flows. The discounted cash flow methodology uses our projections of financial performance for a five-year period. The significant assumptions used in the discounted cash flow methodology are the discount rate, the terminal value and the expected future revenues and profitability.
