Goodwill

Goodwill arises from the acquisition method of accounting for business combinations and represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. The fair values of net tangible assets and intangible assets acquired are based upon preliminary valuations and the Company's estimates and assumptions are subject to change within the measurement period (potentially up to one year from the acquisition date). During the three months ended March 31, 2017, the Company adjusted its allocation of purchase price for the acquisition of the wireless infrastructure backhaul business related to a decrease in an assumed liability and a corresponding decrease in goodwill of $0.3 million (Note 3).

The following table presents the changes in the carrying amount of goodwill:

Goodwill is not amortized, but is assessed for impairment on an annual basis on October 31 each 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. No goodwill impairment was recognized for the three months ended March 31, 2017 and 2016.

Amortization expense related to intangible assets was $4.7 million and $2.1 million in the three months ended March 31, 2017 and 2016, respectively.

The following table sets forth the activity during the three months ended March 31, 2017 related to finite-lived intangible assets resulting from additions, transfers to developed technology from in-process research and development, or IPR&D, and amortization:

The Company regularly reviews the carrying amount of its long-lived assets subject to depreciation and amortization, as well as the useful lives, to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. Should impairment exist, the impairment loss would be measured based on the excess of the carrying amount of the asset over the asset’s fair value. During the three months ended March 31, 2017 and 2016, no impairment losses related to finite-lived intangible assets were recognized.

The Company performs its annual assessment of indefinite-lived intangible assets on October 31 each year or more frequently if events or changes in circumstances indicate that the asset might be impaired utilizing a qualitative test as a precursor to the quantitative test comparing the fair value of the assets with their carrying amount. Based on the qualitative test, if it is more likely than not that indicators of impairment exists, the Company proceeds to perform a quantitative analysis. During the three months ended March 31, 2017 and 2016, no indicators of impairment were identified and, as a result, no impairment of indefinite-lived intangible assets was recorded.
