For our reporting units with goodwill or intangible assets not subject to amortization, we perform impairment tests on an annual basis on August 1, or more frequently if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. All of our goodwill is included in our Parts segment. As part of our goodwill impairment analysis for this reporting unit in the current year, we performed a qualitative assessment. Our intangible assets that are not subject to amortization includes a trademark in our Brazilian engine reporting unit within our Global Operations segment of $17 million and $18 million as of October 31, 2019 and 2018, respectively.
