The allowance for expected credit losses was $85 million at June 30, 2020 and the allowance for doubtful accounts was $73 million at December 31, 2019. Based on the Company's accounting estimates and the facts and circumstances available as of the reporting date, we believe our allowance for expected credit losses is adequate. While we have taken into account certain impacts of COVID-19 in connection with our estimate of the allowance for expected credit losses, it is reasonably possible that additional expected credit losses in excess of such allowance will occur in the coming months as the full extent of the COVID-19 impact becomes more apparent.
