Due to pricing adjustments we made to our vehicle offerings during the year ended December 31, 2019, we estimated that there was a greater likelihood that customers would exercise their buyback options and if customers elect to exercise the buyback option, we expect to be able to subsequently resell the returned vehicles, which resulted in a reduction of cost of automotive sales revenue of $451 million. We made further pricing adjustments that resulted in a similar but smaller reduction of cost of automotive sales revenue of $42 million during the year ended December 31, 2020. Additionally, there was an increase to cost of automotive sales revenue from idle capacity charges of $213 million as a result of temporary suspension of production at the Fremont Factory and Gigafactory Nevada during the first half of 2020.
