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 and six-month periods ended March 31, 2021, however, the fair value of the Mayday reporting unit exceeded carrying value by less than 10%. At March 31, 2021, we had $30 million of goodwill recorded for Mayday.
