Goodwill is not amortized, but is tested for impairment at the reporting unit level using either a qualitative or quantitative assessment on an annual basis during the fourth quarter of each fiscal year, and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The recoverability of goodwill is measured at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair market value of the reporting unit. The reporting units are the same as the operating segments, which aggregate into a single reportable segment (see Note 16 on segment information). For fiscal year 2020, the Company performed a quantitative assessment that demonstrated that the fair value of the reporting units was higher than their respective carrying values. For fiscal years 2019 and 2018, the Company performed a qualitative assessment and concluded that it was more likely than not that the fair value of each of the three reporting units exceeded its carrying value. As of January 26, 2020 and January 27, 2019, there were no indications of impairment of the Company's goodwill balances, and no impairment to goodwill was recorded during fiscal years 2020, 2019 or 2018. Purchased Intangibles The following table sets forth the Company’s finite-lived intangible assets resulting from business acquisitions and technology licenses purchased, which are amortized over their estimated useful lives:

The following table sets forth the Company’s indefinite-lived intangible assets resulting from additions to IPR&D:
(in thousands) | Net Carrying Amount
Value at January 28, 2018 | $ | 2,300 |
Value at January 27, 2019 | 2,300 |
Transfers to core technologies | (2,300 | )
Value at January 26, 2020 | $ | — |
The Company reviews indefinite-lived intangible assets for impairment during the fourth quarter of each fiscal year by comparing the carrying amount of the asset to the future discounted cash flows that the asset is expected to generate. There was no impairment to the Company's indefinite-lived intangible assets during fiscal years 2020, 2019 or 2018. During the fourth quarter of fiscal year 2020, the IPR&D acquired by the Company in connection with the Aptovision acquisition became fully developed and was, therefore, transfered to finite-lived intangible assets as part of core technologies.
