We have one acquired trademark recorded at a cost of $376,000 that was determined to have an indefinite life and is not amortized.

We performed our annual goodwill impairment analysis in the fourth quarter of fiscal year 2018 and no impairment was identified. There have been no triggering events that would indicate a new impairment analysis is needed.
