(2) The goodwill balances in the table above are presented net of accumulated impairment charges of $15.7 million, all of which relate to impairments in periods prior to 2012.

We reviewed our reporting unit structure as part of our annual goodwill impairment testing. We identified several components one level below our operating segments which were determined to be reporting units. We then performed our analysis to determine the proper aggregation of our reporting units, which considered similar economic and other characteristics, including product types, gross profits, production processes, customer types, distribution processes, and regulatory environments. Our analysis incorporated qualitative and quantitative measures to evaluate economic similarity and concluded that our reporting units continue to be equivalent to our operating segments.

A qualitative review of impairment indicators was performed in 2014 for the Residential Heating & Cooling and the Commercial Heating & Cooling segments, and we determined that it was not more likely than not the fair values of our reporting units, individually or collectively, were less than their carrying values. Accordingly, a quantitative impairment analysis was not performed for these segments. Due to the softening of the North American supermarket and Australian wholesale businesses, a quantitative impairment analysis was performed for the Refrigeration segment using the discounted cash flow approach. The Refrigeration segment was not at risk of failing step one of the quantitative impairment test, and no impairments were recognized as part of the annual test. No other indicators of impairment were identified from the date of our annual impairment test through December 31, 2014. Also, we did not record any goodwill impairments related to continuing operations in 2012 or 2013. Refer to Note 17 for information on goodwill related to discontinued operations.
