As a result of the change in segments that became effective as of January 1, 2020, Kodak’s goodwill reporting units changed. Refer to Note 22, “Segment Information” for additional information on the change to Kodak’s organizational structure. The Digital Printing segment has three goodwill reporting units: Electrophotographic Printing Solutions; Prosper and Versamark; and Software. The Advanced Materials and Chemicals segment has three goodwill reporting units: Motion Picture and Industrial Films and Chemicals; Advanced Materials and Functional Printing; and Kodak Services for Business. The Traditional Printing segment and Brand segment each have one goodwill reporting unit.

As of December 31, 2019, the goodwill balance of $12 million under the prior year segment reporting structure was comprised of $6 million for the Brand, Film and Imaging segment and $6 million for the Kodak Software segment, which had only one reporting unit (Software). The goodwill in the Brand, Film and Imaging segment was reported in the Consumer Products reporting unit.

The goodwill previously reported in the Consumer Products goodwill reporting unit was transferred to the Brand goodwill reporting unit using a relative fair value allocation to affected reporting units. Goodwill previously reported in the Software reporting unit was transferred to the Digital Printing segment where it continues to remain its own reporting unit.

Kodak performed interim tests of impairment for goodwill as of June 30, 2020 due to the continued uncertainty regarding the negative impact of the COVID-19 pandemic on its operations, and as of March 31, 2020, due to the decline in market capitalization as of that date since the last goodwill impairment test (December 31, 2019) and the uncertainty regarding the negative impact of the COVID-19 pandemic at that time.
