In the second quarter of 2020, the Motorparts segment initiated a rationalization of its supply chain and distribution network to achieve supply chain efficiencies and improve throughput to its customers. As a result, it was determined that certain assets, including inventory, real estate, and personal property, would no longer be utilized. During the year ended December 31, 2020, the Motorparts segment recognized an $82 million non-cash charge to write-down inventory to its net realizable value. As part of management’s ongoing efforts related to this initiative, during the year ended December 31, 2021, the Motorparts segment recognized a non-cash charge of $44 million to write-down inventory to its net realizable value.
