These additional costs as well as TireHub’s net losses were expected to be temporary and moderate in 2020. However, higher than expected net losses for TireHub continued into 2020, driven by the severe impacts of the COVID-19 pandemic. Accordingly, we evaluated our investment and concluded that there had been an other-than-temporary decline in the fair value of our investment during the second quarter of 2020. As such, we conducted an impairment assessment and estimated the fair value of our investment utilizing updated forecasts of TireHub’s volume, revised expectations as to the extent and duration of, as well as the timing of the recovery from, the COVID-19 pandemic, and an updated discount rate reflective of current market conditions at that time. As a result, during the second quarter of 2020, we recognized a non-cash impairment charge of $148 million. During the second half of 2020, we concluded that there was no additional other-than-temporary decline in the fair value of our investment in TireHub. Nonetheless, there remains a high degree of uncertainty as to the extent and duration of, as well as timing of the recovery from, the COVID-19 pandemic.
