(in thousands) | Signal Integrity |  | Power and High-Reliability |  | Wireless and Sensing |  | Total

During the second quarter of fiscal year 2018, goodwill associated with the Signal Integrity Products Group increased due to the Company’s acquisition of AptoVision (see Note 3). Goodwill is not amortized, but is tested for impairment using either a qualitative assessment or a two-step method on an annual basis 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. Goodwill is allocated to three reporting units (Signal Integrity, Power and High-Reliability and Wireless and Sensing) (see Note 15). The difference between the fair value and the carrying amount of these reporting units is one of several factors the Company will consider before reaching its conclusion about whether to perform the first step of the goodwill impairment test. Goodwill was tested for impairment at the reporting unit level as of November 30, 2017 and November 30, 2016, the dates of the Company’s annual impairment review for fiscal years 2018 and 2017, respectively. For fiscal years 2018 and 2017, 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 such, the Company did not perform a quantitative impairment analysis. In addition to its annual review, the Company performs a test of impairment when indicators of impairment are present. As of January 28, 2018 and January 29, 2017, there were no indications of impairment of the Company's goodwill balances. Acquired Intangibles - The following table sets forth the Company’s finite-lived intangible assets resulting from business acquisitions and technology licenses purchased, which continue to be amortized:
