In the three months ended June 30, 2021, we recorded warranty recall campaign accruals of $1.3 billion, of which $812 million relates to the Chevrolet Bolt EV. We estimate our reasonably possible loss in excess of amounts accrued for recall campaigns to be insignificant at June 30, 2021. Refer to Note 13 to our condensed consolidated financial statements for more details on the Chevrolet Bolt EV recall and Takata Corporation (Takata) matters.
