Following the settlement, certain EC-related claims and lawsuits have been filed in various European jurisdictions against all major European truck manufacturers including the Company and certain subsidiaries. These claims and lawsuits include a number of collective proceedings, including proposed class actions in the United Kingdom, alleging EC-related claims and seeking unspecified damages. In certain jurisdictions, the limitations period has not yet expired and additional claimants may bring EC-related claims and lawsuits against the Company or its subsidiaries. The legal proceedings are continuing to move through the court systems in the various jurisdictions with some larger cases scheduled for trial in 2022.
