Goodwill and Intangible Assets
The Company performs an impairment test for goodwill annually according to the Intangibles—Goodwill and Other Topic of the FASB ASC. On January 1, 2017, the Company also early adopted ASU 2017 No. 2017-04, Intangibles - Goodwill and Other, which eliminates step two of the quantitative goodwill impairment test. The Company first makes a qualitative assessment of the likelihood of goodwill impairment and if it concludes that it is more likely than not that the carrying amount of a reporting unit is greater than its fair value, then it will be required to perform a quantitative impairment test. Otherwise, performing the impairment test is not required. Qualitative factors assessed at the reporting unit level include, but are not limited to, changes in industry and market structure, competitive environments, planned capacity and new product launches, cost factors such as raw material prices and financial performance of the reporting unit. The Company may also determine to skip the qualitative assessment in any year and move directly to the quantitative test.
The quantitative impairment test consists of estimating the fair value and comparing the estimated fair value with the carrying value of the reporting unit. Any goodwill impairment charge is determined by the amount by which the carrying amount exceeds the reporting unit’s fair value. However, the loss should not exceed the total amount of goodwill allocated to the reporting unit. The guidance requires goodwill to be reviewed annually at the same time every year or when an event occurs or circumstances change such that it is reasonably possible that an impairment may exist. The Company selected December 31 as its annual testing date.
In 2018, the Company performed a qualitative assessment of its reporting units which included an evaluation of changes in industry, market and macroeconomic conditions as well as consideration of each reporting unit’s financial performance and any significant trends. In 2018, the Company substantially integrated the operations related to its Nesscap Acquisition in 2017, which included changes to the Company’s reporting structure related to the acquired operations; therefore, the Company determined that it had one reporting unit, which represented a combination of two reporting units from our prior year assessment. The Company first assessed each former reporting separately, and then as a combined, single reporting unit. The Company’s qualitative assessments indicated that it was not more likely that not that goodwill is impaired.
The change in the carrying amount of goodwill during 2017 and 2018 was as follows (in thousands):

The useful life of intangible assets reflects the period the assets are expected to contribute directly or indirectly to future cash flows. Intangible assets are amortized over the useful lives of the assets utilizing the straight-line method, which is materially consistent with the pattern in which the expected benefits will be consumed, calculated using undiscounted cash flows.
For the year ended December 31, 2018, amortization expense of $0.4 million was recorded to “cost of revenue” and $0.9 million was recorded to “selling, general and administrative.” For the year ended December 31, 2017, amortization expense of $0.2 million was recorded to “cost of revenue” and $0.6 million was recorded to “selling, general and administrative.” Estimated amortization expense for the years 2019 through 2023 is $1.2 million each year. The expected amortization expense is an estimate and actual amounts could differ due to additional intangible asset acquisitions, changes in foreign currency rates or impairment of intangible assets.
