(1) | Changes in the gross carrying value during the year ended December 31, 2017 related to foreign currency translation.
Amortization expense was $0.6, $2.8 and $5.2 for the years ended December 31, 2017, 2016 and 2015, respectively. Estimated amortization expense over each of the next five years is $0.6 related to these intangible assets. At December 31, 2017, the net carrying value of intangible assets with determinable lives consisted of $3.8 in the HVAC segment and $1.6 in the Engineered Solutions segment. Trademarks with indefinite lives consisted of $89.5 in the HVAC segment, $10.3 in the Detection and Measurement segment, and $12.4 in the Engineered Solutions segment. 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. Based on our annual goodwill impairment testing in the fourth quarter of 2017, we concluded that the estimated fair value of each of our reporting units exceeds the carrying value of their respective net assets by over 100%. We perform our annual trademarks impairment testing during the fourth quarter, or on a more frequent basis if there are indications of potential impairment. The fair values of our trademarks are determined by applying estimated royalty rates to projected revenues, with the resulting cash flows discounted at a rate of return that reflects current market conditions. The basis for these projected revenues is the annual operating plan for each of the related businesses, which is prepared in the fourth quarter of each year. During 2016, we recorded impairment charges of $30.1 associated with Heat Transfer’s trademarks and definite-lived intangible assets. As of December 31, 2017, the carrying value of Heat Transfer’s intangible assets was $4.9.
