Sale of businesses	Note 10. Sale of businesses In fiscal year 2020, Woodward’s board of directors (“the Board”) approved a plan to divest Woodward’s renewable power systems business, protective relays business, and other businesses within the Company’s Industrial segment (collectively, the “disposal group”). Woodward determined that the approved plan to divest the disposal group represented a triggering event requiring (i) the net assets of the disposal group to be classified as held for sale and (ii) the long-lived assets attributable to the disposal group be assessed for impairment. Given the facts and circumstances at that time, Woodward determined that the value of the long-lived assets of the disposal group, including goodwill, intangible assets, ROU assets and property, plant, and equipment, were not recoverable and a $22,900 non-cash impairment charge was recorded during fiscal year 2020. The non-cash impairment charge removed all the goodwill, intangible assets, ROU assets and property, plant, and equipment associated with the disposal group from the Condensed Consolidated Balance Sheets as of December 31, 2019. Further, on the approval of the divestiture plan and subsequent marketing of the disposal group, Woodward determined that based on the current market conditions, the carrying value of the disposal group’s remaining held for sale net assets exceeded the fair value. As a result, Woodward recorded a valuation allowance to reduce the carrying value of the net assets of the disposal group to their fair value. The non-cash impairment charge associated with the long-lived assets, and related valuation allowance for the other remaining net assets attributable to the disposal group, resulted in a total impairment charge of $37,902.

Note 10. Sale of businesses

In fiscal year 2020, Woodward’s board of directors (“the Board”) approved a plan to divest Woodward’s renewable power systems business, protective relays business, and other businesses within the Company’s Industrial segment (collectively, the “disposal group”).

Woodward determined that the approved plan to divest the disposal group represented a triggering event requiring (i) the net assets of the disposal group to be classified as held for sale and (ii) the long-lived assets attributable to the disposal group be assessed for impairment. Given the facts and circumstances at that time, Woodward determined that the value of the long-lived assets of the disposal group, including goodwill, intangible assets, ROU assets and property, plant, and equipment, were not recoverable and a $22,900 non-cash impairment charge was recorded during fiscal year 2020. The non-cash impairment charge removed all the goodwill, intangible assets, ROU assets and property, plant, and equipment associated with the disposal group from the Condensed Consolidated Balance Sheets as of December 31, 2019.

Further, on the approval of the divestiture plan and subsequent marketing of the disposal group, Woodward determined that based on the current market conditions, the carrying value of the disposal group’s remaining held for sale net assets exceeded the fair value. As a result, Woodward recorded a valuation allowance to reduce the carrying value of the net assets of the disposal group to their fair value. The non-cash impairment charge associated with the long-lived assets, and related valuation allowance for the other remaining net assets attributable to the disposal group, resulted in a total impairment charge of $37,902.
