(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 2018. (2) In 2019, we reorganized our external financial reporting structure by moving our European Commercial HVAC business from our Commercial segment to our Refrigeration segment as we manage both our commercial HVAC and refrigeration operations in Europe together. See Note 3 for additional information. A qualitative review of impairment indicators was performed in 2020 for the Residential Heating & Cooling, the Commercial Heating & Cooling, and the Refrigeration segments. We did not record any goodwill impairments in 2020 or 2019. In 2018, we de-recognized $11.5 million of goodwill as a part of the completed sales of our Australia, Asia, and South America businesses as discussed further in Note 7.
