The economic uncertainty, changes in the propensity for the general public to travel by air, and reductions in demand for commercial aircraft as a result of the COVID-19 pandemic have adversely impacted net sales and operating results in certain of

the Aerospace and Defense reporting units. There were no impairment charges incurred for the three months ended December 31, 2020, however, the fair value of the Mayday reporting unit exceeded carrying value by slightly less than 10%. At December 31, 2020, we had $30 million of goodwill recorded for Mayday.
