(1) The goodwill balances in the table above are presented net of accumulated impairment charges of $32.7 million, all of which relate to impairments in periods prior to 2021.

(2) As discussed in Note 3, we recast our segment presentation to present our Heatcraft Worldwide Refrigeration business as a component of our Building Climate Solutions segment and our European portfolio as a component of Corporate and Other. Since there is no longer a Refrigeration segment, we allocated goodwill to each segment based upon the relative fair value of the business.

(3) There was $4.6 million of goodwill related to our European portfolio. As part of the loss on assets held for sale that was recorded in the third quarter of 2023, we recorded an impairment of $2.3 million for a portion of the goodwill transferred. The remaining goodwill was included in the balance of disposed net assets.

(4) On October 25, 2023, we announced the acquisition of AES. In connection with this acquisition, $40.4 million of goodwill was recorded and included in the Building Climate Solutions reporting unit. AES is included in the Building Climate Solutions segment. See Note 18 for additional information on the AES acquisition.
