⁽¹⁾: Recorded impairment charges during 2012 of $4.5 associated with two businesses within our Thermal Equipment and Services reportable segment and impairment charges during 2011 of $7.5 and $0.8 associated with businesses within our Thermal Equipment and Service reportable segment and Industrial Products and Services, respectively.

Amortization expense was $35.1, $23.3 and $20.7 for the years ended December 31, 2012, 2011 and 2010, respectively. Estimated amortization expense related to these intangible assets is $36.9 in 2013, $30.6 in 2014, $30.2 in 2015, $29.9 in 2016, and $29.9 in 2017.

At December 31, 2012, the net carrying value of intangible assets with determinable lives consisted of $459.7 in the Flow Technology reportable segment, $52.4 in the Thermal Equipment and Services reportable segment, and $9.7 in Industrial Products and Services. Trademarks with indefinite lives consisted of $290.5 in the Flow Technology reportable segment, $134.6 in the Thermal Equipment and Services reportable segment, and $15.5 in Industrial Products and Services.

Consistent with the requirements of the Intangible — Goodwill and Other Topic of the Codification, the fair values of our reporting units generally are estimated using discounted cash flow projections that we believe to be reasonable under current and forecasted circumstances, the results of which form the basis for making judgments about carrying values of the reported net assets of our reporting units. Other considerations are also incorporated, including comparable industry price multiples. Many of our reporting units closely follow changes in the industries and end markets that they serve. Accordingly, we consider estimates and judgments that affect the future cash flow projections, including principal methods of competition such as volume, price, service, product performance and technical innovations and estimates associated with cost improvement initiatives, capacity utilization and assumptions for inflation and foreign currency changes. Any significant change in market conditions and estimates or judgments used to determine expected future cash flows that indicate a reduction in carrying value may give rise to impairment in the period that the change becomes known.

We perform our annual goodwill impairment testing during the fourth quarter in conjunction with our annual financial planning process, with such testing based primarily on events and circumstances existing as of the end of the third quarter. In addition, we test goodwill for impairment on a more frequent basis if there are indications of potential impairment. In connection with our annual goodwill testing during the fourth quarter of 2011, we estimated that the fair value of our Cooling Equipment and Services ("Cooling") reporting unit was approximately 5% higher than the carrying value of its net assets as its projected, near-term cash flows were being negatively impacted by the challenging conditions within the power generation end-markets in which the business participates. During the first three quarters of 2012, orders and operating results remained below historical levels. Despite an improvement in order levels and profitability during the fourth quarter of 2012, our current cash flow estimates for the business, based on the related 2013 operating plan that was completed by the end of 2012, as well as other market related data, indicate that the current estimated fair value of the business is below the carrying value of its net assets. As a result, we estimated the implied fair value of Cooling's goodwill, which resulted in an impairment charge related to such goodwill of $270.4. The impairment charge of $270.4 is composed of (i) a $125.8 difference between the estimated fair value of Cooling compared to the carrying value of its net assets and (ii) an allocation to certain tangible and intangible assets of $144.6 for the estimated increases in fair value for these assets solely for purposes of applying the impairment provisions of the Intangible — Goodwill and Other Topic of the Codification. After the impairment charge, goodwill for the Cooling reporting unit totaled $82.9 as of December 31, 2012. The estimated fair value for each of our other reporting units with goodwill, except for Clyde Union, exceeded the carrying value of their respective net assets by at least 20.0%. The estimated fair value of Clyde Union exceeded the carrying value of its net assets by approximately 2.0%, while the total goodwill for Clyde Union was $381.7 at December 31, 2012. A change in any of the assumptions used in testing Clyde Union's goodwill for impairment (e.g., projected revenue and profit growth rates, discount rate, expected control premium, etc.) could result in Clyde Union's estimated fair value being less than the carrying value of its net assets. For example, a one-hundred basis point increase in the discount rate used in determining Clyde Union's discounted cash flows would result in Clyde Union's fair value being approximately $66.0 lower than the carrying value of its net assets. If Clyde Union is unable to achieve the financial forecasts included in its 2012 annual goodwill impairment analysis, we may be required to record an impairment charge in a future period related to Clyde Union's goodwill.

In addition to the goodwill impairment charge of $270.4, we also recorded an impairment charge of $11.0 in 2012 related to certain long-term assets of our Cooling reporting unit. Lastly, we recorded impairment charges of $4.5 in 2012 related to trademarks for two other businesses within our Thermal Equipment and Services reportable segment.

In connection with our annual goodwill impairment testing in 2010, we determined that the estimated fair value of our SPX Heat Transfer Inc. reporting unit was comparable to the carrying value of its net assets. In the second quarter of 2011, SPX Heat Transfer Inc. experienced a decline in its revenues and profitability, furthering a trend that began late in the first quarter of 2011, in comparison to (i) recent historical results and (ii) expected results for the period, due to the challenging conditions within the U.S. power market. As such, during the second quarter of 2011, we updated the projection of future discounted cash flows for SPX Heat Transfer Inc. which indicated that the reporting unit's fair value was less than the carrying value of its net assets. Accordingly, we recorded an impairment charge of $24.7 during the second quarter of 2011 associated with SPX Heat Transfer Inc.'s goodwill ($17.2) and indefinite-lived intangible assets ($7.5). In connection with our annual goodwill impairment testing during the fourth quarter of 2011, and in consideration of a further decline in SPX Heat Transfer Inc.'s revenue and profitability, we determined that the remaining goodwill ($3.6) of the reporting unit was impaired and, thus, recorded an impairment charge of $3.6 during the fourth quarter of 2011.
