Goodwill and Intangible Assets
Goodwill. Goodwill is related to our acquisitions of the Chandler, Arizona (Extrusion) facility and the Florence, Alabama facility and is included in the Fabricated Products segment. The carrying value of our goodwill was $18.8 million as of December 31, 2017 and $37.2 million at both the beginning and the end of the year ended December 31, 2016. The carrying value as of December 31, 2017 included accumulated impairment of $18.4 million. There was no accumulated impairment reflected in the carrying values at both the beginning and the end of the year ended December 31, 2016.
Several factors identified in a qualitative review in the quarter ended June 30, 2017 indicated that long-term demand for hard alloy extruded shapes produced at the Chandler, Arizona (Extrusion) facility was less than previously assumed. Such factors included: (i) reduced build rates of wide body commercial aircraft; (ii) continued low build rates for business jets; and (iii) additional substitution away from hard alloy extruded shapes in favor of composites, titanium and/or aerospace aluminum plate in the manufacture of commercial aircraft. After testing for goodwill impairment applying Level 3 inputs and a combination of an income approach using the estimated discounted cash flow and a market-based valuation methodology, we impaired the carrying value of the goodwill related to our Chandler, Arizona (Extrusion) facility by $18.4 million as of June 30, 2017. As this goodwill is deductible for income tax purposes, the deferred tax effects were included in the impairment charge and income tax provision.
During our annual goodwill impairment test in the quarter ending December 31, 2017, we performed a quantitative impairment test and determined that no additional impairment of our goodwill was required.
Intangible Assets. In 2017 and 2016, our identifiable intangible assets related to acquired finite-lived customer relationships. Information regarding the gross carrying amount and accumulated amortization of these intangible assets was as follows as of each period presented:

We recorded a $2.6 million non-cash impairment charge within Other operating charges, net during the quarter ended September 30, 2016 due to the loss of a customer. We identified no other indicators of impairment associated with the remainder of our intangible assets during the years ended December 31, 2017, December 31, 2016 or December 31, 2015.
Amortization expense relating to definite-lived intangible assets is recorded in the Fabricated Products segment over a weighted-average useful life of 25 years. Such expense was $1.4 million for 2017, $1.5 million for 2016, and $1.6 million for 2015. The expected amortization of intangible assets for each of the next five calendar years is $1.4 million and $18.0 million for years thereafter.
