Goodwill and Intangible Assets Disclosure [Abstract]

The carrying amount and accumulated amortization of the Company's software assets subject to amortization at each balance sheet date are as follows (in thousands):


	September 30, 2023						December 31, 2022
	Gross Carrying Amount		Accumulated Amortization		Net Balance		Gross Carrying Amount		Accumulated Amortization		Net Balance
Software for internal use	$	456,840	$	(351,516)	$	105,324	$	454,171	$	(325,062)	$	129,109

Amortization of software for internal use is computed using the straight-line method over an estimated useful life of generally three to eight years. Software for internal use amortization expense recorded during the three months ended September 30, 2023 and 2022, totaled $16.3 million and $17.3 million, respectively. Software for internal use amortization expense recorded during the nine months ended September 30, 2023 and 2022, totaled $49.3 million and $51.1 million, respectively. These software amortization expense amounts are reflected in depreciation and amortization in the condensed consolidated statements of operations.

Amortization of software for resale was computed using the greater of (a) the ratio of current gross revenues to the total of current and future gross revenues expected to be derived from the software or (b) the straight-line method over the remaining estimated useful life of generally five to ten years. Software for resale amortization expense recorded during the nine months ended September 30, 2022 totaled $0.7 million. Software for resale was fully amortized during the first quarter of 2022 and, therefore, there was no amortization expense recorded during the three months ended September 30, 2022, or the three and nine months ended September 30, 2023. The software amortization expense amount was reflected in cost of revenue in the condensed consolidated statements of operations.
