The Company assesses potential impairment of its goodwill and intangible assets when there is evidence that events or circumstances have occurred that would indicate the recovery of an asset’s carrying value is unlikely. The Company also assesses potential impairment of its goodwill and intangible assets on an annual basis regardless of whether there is evidence of impairment. If indicators of impairment were to be present in intangible assets used in operations and future discounted cash flows were not expected to be sufficient to recover the asset’s carrying amount, an impairment loss would be charged to expense in the period identified. The amount of an impairment loss that would be recognized is the excess of the asset’s carrying value over its fair value. Factors the Company considers important, which may cause impairment include, among others, significant changes in the manner of use of the acquired asset, negative industry or economic trends, and significant underperformance relative to historical or projected operating results.

The Company typically conducts its annual impairment analysis in the fourth quarter of its fiscal year. The impairment analysis did not result in an impairment charge for the fiscal year ended December 31, 2018. Determining the fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The Company bases its fair value estimates on assumptions that it believes are reasonable but are uncertain and subject to changes in market conditions.

Intangible assets with finite useful lives are amortized over their respective useful lives. Based on the carrying values at March 31, 2019 and assuming no subsequent impairment of the underlying assets, the amortization expense is expected to be $0.7 million for the remainder of fiscal year 2019, and $0.1 million in 2020 through 2025.
