We test amortizable intangible assets for impairment when indicators of impairment exist. No impairment was recorded for any period presented.

Amortization expense relating to amortizable intangible assets for the years ended December 30, 2023, December 31, 2022, and January 1, 2022, respectively, was $26.3 million, $26.2 million, and $21.1 million, respectively, classified within selling, general and administrative expenses in the accompanying consolidated statements of operations. Accumulated amortization at December 30, 2023, and December 31, 2022 was $191.1 million and $164.8 million, respectively, and is composed of the accumulated amortization of the components of amortizable intangible assets, as follows: Customer relationships and customer-related assets - $174.9 million and $153.6 million; Trade name (amortizable) - $5.8 million and $4.3 million; Developed technology - $6.9 million and $3.7 million; Non-compete agreement - $3.0 million and $2.6 million; and, Software license - $0.6 million and $0.6 million.

We perform our annual goodwill impairment testing on the first day of our fiscal fourth quarter of each year, and at interim periods if needed based on occurrence of triggering events. The Company performed a qualitative assessment for each reporting unit. The qualitative assessments indicated that it was more likely than not that the fair value of each reporting unit exceeded its respective carrying value. As of December 30, 2023, and December 31, 2022, the carrying value of our Southeast reporting unit goodwill was $228.3 million and $228.3 million, respectively. As of December 30, 2023, and December 31, 2022, the carrying value of our Western reporting unit goodwill is $234.3 million and $232.1 million, respectively.

We perform our annual indefinite-lived intangible asset impairment testing on the first day of our fiscal fourth quarter of each year, and at interim periods if needed based on occurrence of triggering events.

In 2023, because of post-acquisition sales levels below those used in its initial valuation, we determined such conditions represented a triggering event and that we should complete a quantitative impairment test of our Martin trade name as of our annual impairment test date of the first day of our fourth quarter of 2023. Based on our revised modeling, which included our assumptions regarding future revenue, which we consider to be a Level 3 input, using the relief-from-royalty method, we concluded that the fair value of our Martin trade name was less than its carrying value, which resulted in an impairment of our Martin trade name of $5.5 million in our fourth quarter of 2023. As of December 30, 2023, and December 31, 2022, the carrying value of our Martin trade name was $18.5 million and $24.0 million, respectively.

In 2022, given the narrow excess of fair value over carrying value of our WinDoor trade name in the first quarter of 2020, the last time we performed a quantitative assessment of our WinDoor trade name, and the then recent decrease in sales of our WinDoor brand, we determined such conditions represented triggering events and that we should complete a quantitative impairment test of our WinDoor trade name as of our annual impairment test date of the first day of our fourth quarter of 2022. Based on our revised modeling, which included our assumptions regarding future revenue, which we consider to be a Level 3 input, using the relief-from-royalty method, we concluded that the fair value of our WinDoor trade name was less than its carrying value, which resulted in an impairment of our WinDoor trade name of $7.4 million in our fourth quarter of 2022. As of December 30, 2023, and December 31, 2022, the carrying value of our WinDoor trade name was $11.0 million and $11.0 million, respectively.

For our other indefinite-lived trade names, we completed qualitative assessments of these assets on the first day of our fourth quarter of 2023. These qualitative assessments included an evaluation of relevant events and circumstances that existed at the date of

our assessment. Those events and circumstances included conditions specific to our other indefinite-lived trade names, such as the industry in which we use these other indefinite-lived trade names, our competitive environment, the availability and costs of raw materials and labor, the financial performance of our Company, and factors related to the markets in which our Company operates. We also considered that, for our other indefinite-lived trade names, no new impairment indicators were identified since the dates of our prior assessments, which were qualitative assessments all other indefinite-lived intangibles other than goodwill. Based on these assessments, we concluded that it is more likely than not that the fair values of our other indefinite-lived trade names exceed their carrying values. As of December 30, 2023, and December 31, 2022, excluding the Martin trade name, the carrying values of other indefinite-lived trade names were $201.0 million and $201.0 million, respectively.
