The Company assesses goodwill and other indefinite-lived intangible assets for impairment on an annual basis as of October 1, and more frequently if there are changes in the business climate or as a result of a triggering event taking place. During the third quarter of 2020, as a result of a decline in its aerospace-related business' financial results, a significant reduction in its financial projections for the remainder of 2020 compared with prior projections, and uncertainty around the duration and magnitude of the impact of the COVID-19 pandemic on future financial results given their dependence on future levels of air travel and new aircraft builds, the Company determined there was a triggering event requiring an interim quantitative goodwill impairment assessment of each of its two aerospace-related reporting units: Aerospace Fasteners and Aerospace Engineered Products.

Upon completion of the quantitative goodwill impairment tests, the Company determined that the carrying values of the Aerospace Fasteners and Aerospace Engineered Products reporting units exceeded their fair values, resulting in goodwill impairment charges of approximately $70.8 million in its Aerospace Fasteners reporting unit and approximately $56.0 million in its Aerospace Engineered Products reporting unit during the three and nine month periods ended September 30, 2020.
