Goodwill And Intangible Assets Disclosure [Abstract] |
Goodwill | Note 7 - Goodwill: All of our goodwill recognized is related to our component products operations and was generated from CompX’s acquisitions of certain business units. There have been no changes in the carrying amount of our goodwill during the past three years. We have assigned goodwill related to the component products operations to two reporting units (as that term is defined in ASC Topic 350-20-20 Goodwill): one consisting of CompX’s security products operations and one consisting of CompX’s marine component operations. We test for goodwill impairment at the reporting unit level. In accordance with ASC 350-20-35, we test for goodwill impairment during the third quarter of each year or when circumstances arise that indicate an impairment might be present. In 2014, 2015 and 2016, our goodwill was tested for impairment only in the third quarter of each year in connection with our annual testing. No impairment was indicated as part of such annual review of goodwill. As permitted by GAAP, during 2014 and 2015 we used the qualitative assessment of ASC 350-20-35 for our annual impairment test and determined it was not necessary to perform the two-step quantitative goodwill impairment test. During 2016, we used the quantitative assessment of ASC 350-20-35 for our 2016 annual impairment test using discounted cash flows to determine the estimated fair value of our Security Products reporting unit. Such discounted cash flows are a Level 3 input as defined by ASC 820-10-35. Prior to 2014, all of the goodwill related to CompX’s marine components operations (which aggregated $10.1 million) was impaired, and all of the goodwill related to our wholly-owned subsidiary EWI Re, Inc., (EWI) an insurance brokerage and risk management services company (which aggregated $6.4 million) was impaired. Our gross goodwill at December 31, 2016 was $43.7 million.
