As a result of the Company’s divestiture of the GBL division and decision to retain the HPC division, the Company reconsidered the way management views its business activities and reportable segments; which also changed the reporting units that the Company utilizes to recognize goodwill. Spectrum had historically recognized goodwill at its Global Batteries and Appliance (GBA) reporting unit and separate operating segment. With the separation of the GBL and HPC components, goodwill previously recognized as part of the GBA reporting unit was allocated to HPC and the GBL discontinued operations, based upon relative fair value, during the first quarter when the decision was made to retain the HPC division and separate HPC assets from the GBL assets. No goodwill impairment was recorded in connection with the GBL divestiture and change to the plan of sale of the HPC division. Refer to Note 3 - Divestitures and Note 19 - Segment information for further discussion.
