(3) Goodwill acquired in connection with the acquisition of BlueData.

Goodwill is tested for impairment at the reporting unit level. As of July 31, 2019, the Company's reporting units containing goodwill are consistent with the reportable segments identified in Note 2, "Segment Information". The Company will continue to evaluate the recoverability of goodwill on an annual basis as of the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate there may be a potential impairment.
