GOODWILL AND OTHER INTANGIBLE ASSETS |
GOODWILL AND OTHER INTANGIBLE ASSETS | 5. GOODWILL AND OTHER INTANGIBLE ASSETS Our intangible assets consist of goodwill, customer relationships, supply contracts, technology and trade names. Goodwill is the excess of the cost of an acquired entity over the fair value of tangible and intangible assets (including, but not limited to, customer relationships, supply contracts, technology and trade names) acquired and liabilities assumed under acquisition accounting for business combinations. Goodwill. As of June 30, 2015, we have two segments that contain reporting units with goodwill and intangible assets: our chlorovinyls segment includes goodwill in its chlor-alkali and derivatives and compound reporting units and our building products segment includes goodwill primarily in its siding reporting unit. The following table provides the detail of the changes made to goodwill during the six months ended June 30, 2015.

Indefinite-lived intangible assets. As of June 30, 2015 and December 31, 2014, our indefinite-lived intangible assets consisted of certain trade names with a carrying value of $5.9 million and $6.0 million, respectively, net of cumulative translation adjustment. Definite-lived intangible assets. As of June 30, 2015 and December 31, 2014, we had definite-lived intangible assets related to: (i) customer relationships, supply contracts, technology and trade names in our chlorovinyls segment; and (ii) customer relationships and technology in our building products segment.

The weighted average estimated useful lives remaining for customer relationships, supply contracts, technology and definite-lived trade names are approximately 16 years, 18 years, 16 years and 15 years, respectively, as of June 30, 2015. Amortization expense for the definite-lived intangible assets was $16.7 million and $16.8 million for the three months ended June 30, 2015 and 2014, respectively, and $33.3 million and $33.6 million for the six months ended June 30, 2015 and 2014, respectively. The estimated annual amortization expense for definite-lived intangible assets for the next five fiscal years is approximately $66.4 million per year. Valuation of Goodwill and Indefinite-Lived Intangible Assets. The carrying values of our goodwill and indefinite-lived intangible assets are tested for impairment annually in the fourth quarter, using a measurement date of October 1. In addition, we evaluate the carrying values of these assets for impairment between annual impairment tests if an event occurs or circumstances change that would indicate the carrying amounts may be impaired. Such events and indicators may include, without limitation, significant declines in the industries in which our products are used, significant changes in the estimated future cash flows of our reporting units, significant changes in capital market conditions and significant changes in our market capitalization. During the quarter ended June 30, 2015 we determined there were circumstances that required us to perform an interim impairment test in our reporting units that carry goodwill and indefinite-lived intangible assets. These factors include, but are not limited to the operating results during the six months ended June 30, 2015, the sustained deterioration of our industry market conditions and the resulting decline in our market capitalization. Impairment testing for goodwill is a two-step test performed at the reporting unit level. The first step of the impairment analysis involves comparing the fair value of the reporting unit to its book value, including goodwill. If the fair value of the reporting unit exceeds the book value, goodwill is not considered impaired. If the book value exceeds the fair value, the second step of the impairment analysis is performed, in which we measure the amount of impairment. Our goodwill evaluations utilize discounted cash flow analyses and market multiple analyses in estimating fair value. The weighting of the discounted cash flow and market approaches vary by each reporting unit based on factors specific to each reporting unit. Inherent in our fair value determinations are certain judgments and estimates relating to future cash flows, including our interpretation of current economic indicators and market conditions, overall economic conditions and our strategic operational plans with regard to our business units. In addition, to the extent significant changes occur in market conditions, overall economic conditions or our strategic operational plan, it is possible that goodwill not currently impaired, may become impaired in the future. Based on our analysis, the estimated fair values of our compound and siding, reporting units exceeded the carrying values in each respective unit by more than 10 percent. The estimated fair value of our chlor-alkali and derivatives unit exceeded its carrying value at an amount that was less than 10 percent. Management does not believe the reporting unit is impaired and has not recorded an impairment charge. Management will continue to monitor the reporting unit for any future indicators of impairment.
