As a result of the January 2023 segment change, the Company reviewed the recoverability of the carrying value of goodwill of its Alumina reporting unit in the first quarter of 2023. The estimated fair value of the Alumina reporting unit substantially exceeded the reporting unit’s carrying value, resulting in no impairment.

Goodwill, which is included in Other noncurrent assets on the accompanying Consolidated Balance Sheet, was as follows:


	June 30, 2023		December 31, 2022
Alumina	$	4	$	4
Aluminum		—		—
Corporate(1)		142		141
	$	146	$	145

(1)

The carrying value of Corporate’s goodwill is net of accumulated impairment losses of $742 as of both June 30, 2023 and December 31, 2022. As of June 30, 2023, the $142 of goodwill reflected in Corporate is allocated to Alcoa Corporation’s Alumina reportable segment for purposes of impairment testing. This goodwill is reflected in Corporate for segment reporting purposes because it is not included in management’s assessment of performance by the reportable segment. Changes in the carrying amount of goodwill were attributable to foreign currency translation as of June 30, 2023 and December 31, 2022.
