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 lists, supply contracts, technology and trade names) acquired and liabilities assumed under acquisition accounting for business combinations. Goodwill. As of March 31, 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 three months ended March 31, 2015.
