Reporting Units

In accordance with ASC 350, Intangibles - Goodwill and Other, the Company determined its reporting units based upon whether discrete financial information is available and if management regularly reviews the operating results of the component. As of June 30, 2022, the Company was comprised of three operating and reportable segments and reporting units: OSI, Inc., SSE and Heritage AspenTech. During the three months ended September 30, 2022, the Company completed certain integration activities and changes to its organizational structure that triggered a change in the composition of its operating and reportable segments. As a result, beginning with the interim period ended September 30, 2022, the Company is now comprised of a single operating and reportable segment. See Note 22 “Segment and Geographic Information” for further information on the change to the Company’s operating and reportable segments. In conjunction with the change in operating and reportable segments, the Company also changed the composition of its reporting units. Beginning with the interim period ended September 30, 2022, the Company is now comprised of a single reporting unit. The Company performed goodwill impairment assessments on each reporting unit immediately before and after the change in organizational structure and concluded that there was no goodwill impairment.
