•Percentage by which fair value exceeded carrying value as of the date of the most recent test;

•Amount of goodwill allocated to the reporting unit

Response: The Company acknowledges the Staff’s comment and respectfully advises the Staff that the Company has two reporting units where goodwill is allocated and tested for impairment: Fire Safety and Specialty Products. The Company advises the Staff that as of October 1, 2022, which is the date of the most recent annual impairment test, the fair value of its Fire Safety reporting unit exceeded its carrying value by 12.2% and the fair value of its Specialty Products reporting unit exceeded its carrying value by 65.7%. As of October 1, 2022, the Fire Safety and Specialty Products reporting units had goodwill of $851.9 million and $167.5 million, respectively. Based on this, the Company has determined that each of its reporting units have a fair value substantially in excess of carrying value. The Company advises the Staff that in future filings, it will disclose when no reporting units are at risk of impairment. If subsequent impairment tests indicate that a reporting unit is at risk, the Company will disclose (i) the amount of goodwill allocated to the reporting unit , (ii) the percentage by which fair value exceeds carrying value, and (iii) qualitative and quantitative information necessary to understand potential events and/or changes in circumstances that could reasonably be expected to negatively affect the key assumptions.
