Goodwill And Intangible Assets Disclosure [Abstract] |
Goodwill | ​ ​ Note 7 - Goodwill: All of our goodwill 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 assign goodwill based on the reporting unit (as that term is defined in ASC Topic 350-20-20 Goodwill) which corresponds to CompX’s security products 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 2019, 2020 and 2021, 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 2019, 2020 and 2021 we used the qualitative assessment of ASC 350-20-35 for our annual impairment test and determined it was not necessary to perform the quantitative goodwill impairment test. Such discounted cash flows are a Level 3 input as defined by ASC 820-10-35. Prior to 2019, 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, 2021 was $43.7 million.
