In connection with the acquisition of SAC Sirius Advanced Cybernetics GmbH ("SAC") in the fourth quarter of 2022 (refer to Note 21), the Company acquired completed technologies valued at $3,800,000 with an estimated useful life of 7 years.

In 2022, the Company retired approximately $43,280,000 of intangible assets primarily related to distribution networks and customer relationships that were fully amortized and had a net carrying value of zero on the Consolidated Balance Sheets.

The adverse impact of the COVID-19 pandemic on our business in 2020 triggered a review of long-lived assets, including intangible assets, for potential impairment during the second quarter of 2020. Based on this assessment, management concluded that certain of the Company's finite-lived intangible assets failed the recoverability test, and recorded impairment charges for these assets equal to the amount by which their carrying value exceeded their fair value. The Company also measured the fair value and recorded an impairment charge for its indefinite-lived intangible asset related to in-process technologies. The fair values were established, with the assistance of an outside valuation advisor, using the income approach based on a discounted cash flow model that estimated future revenue streams and expenses attributable to those revenue streams provided by management.

This review resulted in intangible asset impairment charges totaling $19,571,000 in the second quarter of 2020, primarily related to lower projected cash flows from the technologies and customer relationships acquired from Sualab Co. Ltd. ("Sualab") as a result of the deteriorating global economic conditions from the COVID-19 pandemic. Completed technologies, in-process technologies, and customer relationships acquired from Sualab were impaired in the amounts of $10,070,000, $5,900,000, and $3,382,000, respectively. In addition, customer relationships acquired from EnShape GmbH that had a gross carrying value of $447,000 and accumulated amortization of $228,000 on the measurement date were reduced to zero, resulting in an impairment charge of $219,000. The Company did not record impairment charges related to intangible assets in 2022 or 2021.

Estimated amortization expense for each of the five succeeding fiscal years and thereafter is as follows (in thousands):
