5. | Goodwill
The Company tests goodwill at least annually for impairment. The Company tests more frequently if indicators are present or changes in circumstances suggest that impairment may exist. These indicators include, among others, declines in sales, earnings or cash flows, or the development of a material adverse change in the business climate. The Company assesses goodwill for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. At the beginning of the fourth quarter of 2017, the Company performed a qualitative assessments for its annual goodwill impairment analysis, which did not result in an impairment charge for either the BioStim or Biologics reporting units, the only reporting units with goodwill. This qualitative analysis considers all relevant factors specific to the reporting units, including macroeconomic conditions, industry and market considerations, overall financial performance, and relevant entity-specific events. In 2016 the Company performed a quantitative impairment analysis that did not result in an impairment charge and in 2015 the Company performed a qualitative assessment, which did not result in any impairment charge. The following table presents the net carrying value of goodwill by reportable segment:
