Engine System Campaign Accrual
During 2017, the California Air Resources Board (CARB) and the U.S. Environmental Protection Agency (EPA) selected certain of our pre-2013 model year engine systems for additional emissions testing. Some of these engine systems failed CARB and EPA tests as a result of degradation of an aftertreatment component. In the second quarter of 2018, we reached agreement with the CARB and EPA regarding our plans to address the affected populations. From the fourth quarter of 2017 through the second quarter of 2018, we recorded charges for the expected costs of field campaigns to repair these engine systems.

The campaigns launched in the third quarter of 2018 are being completed in phases across the affected population. The total engine system campaign charge, excluding supplier recoveries, was $410 million. In the fourth quarter of 2020, we recorded an additional $20 million charge related to this campaign, as a change in estimate, to bring the total campaign, excluding supplier recoveries, to $430 million. At July 4, 2021, the remaining accrual balance was $109 million.
