[1] Pricing adjustments on our vehicle offerings can impact the estimate of likelihood that customers would exercise their resale value guarantees, resulting in an adjustment of our sales return reserve on vehicles sold with resale value guarantees. Actual return rates being lower than expected and increases in resale values of our vehicles in 2021 resulted in a net release of our reserve of $365 million for the year ended December 31, 2021, which represented increases in automotive sales revenue. The net release or increase of reserves which impacted automotive sales revenue were immaterial for the years ended December 31, 2022 and December 31, 2020. Further, $324 million of the total revenue recognized as of December 31, 2022 is related to the general FSD feature release in North America in the fourth quarter of 2022.
