_________________

(1)    The total carrying amount of goodwill for all periods in the table above is reflected net of $1.557 billion of accumulated impairment charges, which were primarily recorded in our general rentals segment.

(2)    Includes goodwill adjustments for the effect on goodwill of changes to net assets acquired during the measurement period, which were not significant to our previously reported operating results or financial condition. Decreases in goodwill related to acquisitions above primarily reflect such measurement period adjustments.

(3)    For additional detail on the December 2022 acquisition of Ahern Rentals, which was assigned to our general rentals segment and accounted for most of the goodwill related to acquisitions in 2022, see note 4 to our consolidated financial statements. The decrease in goodwill related to acquisitions for the general rentals segment in 2023 primarily reflects measurement period adjustments associated with the Ahern Rentals acquisition, partially offset by other acquisition activity.

Other intangible assets were comprised of the following at December 31, 2023 and 2022:  

	December 31, 2023
	Weighted-Average Remaining Amortization Period	Gross Carrying Amount		Accumulated Amortization		Net Amount
Non-compete agreements	4 years	$	176	$	58	$	118
Customer relationships	6 years	$	2,468	$	1,919	$	549

Customer relationships	5 years	$	2,349	$	1,949	$	400
Trade names and associated trademarks	3 years	$	14	$	9	$	5

Our other intangibles assets, net at December 31, 2023 include the assets set forth in the table below associated with the acquisition of Ahern Rentals that is discussed in note 4 to our consolidated financial statements. No residual value has been assigned to these assets. The non-compete agreements are being amortized on a straight-line basis and the customer relationships are being amortized using the sum of the years' digits method, and we believe that such methods best reflect the estimated pattern in which the economic benefits will be consumed.

	December 31, 2023
	Weighted-Average Remaining Amortization Period	Net Carrying Amount
Non-compete agreements	4 years	77
Customer relationships	8 years	259

Amortization expense for other intangible assets was $271, $219 and $233 for the years ended December 31, 2023, 2022 and 2021, respectively.

As of December 31, 2023, estimated amortization expense for other intangible assets for each of the next five years and thereafter was as follows: 

2024	$	208
