As a result of recent operating losses within our Commercial and Industrial business, we determined that an indicator of a potential goodwill impairment was present. As a result of this indicator, we performed a quantitative goodwill impairment assessment as of March 31, 2020. Based on the results of this assessment, we concluded that the fair value of our Commercial and Industrial reporting unit remains in excess of its carrying value, and therefore, we have not recorded an impairment charge for the quarter ended March 31, 2020. Our estimate of implied fair value requires us to use significant unobservable inputs, representative of Level 3 fair value measurements, including numerous assumptions with respect to future circumstances, such as industry and/or local market conditions, including the impact of COVID-19 on our business, that might directly impact the future performance of our business, and are therefore uncertain.

As of March 31, 2020, it is reasonably possible that judgments and estimates of certain key assumptions, including our internal forecasts or the external market conditions, could change in future periods and may result in a reduction in fair value. Significant adverse changes in future periods to these key assumptions, if any, could reasonably be expected to negatively affect our estimate of implied fair value, and may result in future goodwill impairment charges.
