Depreciation expense was $568.1 million, $702.0 million and $637.8 million in 2021, 2020 and 2019, respectively. The decrease in depreciation expense for the year ended December 31, 2021 compared to 2020 was primarily due to the decrease in accelerated depreciation recorded as a result of certain facility closures as well as assets becoming fully depreciated during the year. Accelerated depreciation recorded during the years ended December 31, 2021, 2020 and 2019 was $15.4 million, $112.3 million and $31.7 million respectively.
