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 awaiting judgment in 2022 and others scheduled for trial in upcoming years.
