During the first quarter of 2019, in connection with the Separation and the Acquisition, we made significant changes to our organizational and reporting structure. With these changes, we revised our reportable segments. Goodwill was reallocated to the new reporting segments, and as a result, an impairment assessment was performed. There were no goodwill impairment losses recorded during the six months ended June 30, 2019 or the full year of 2018, and we have no accumulated impairment losses. For further information regarding the segment change, see Note 13 - Segment Data.
