X Chemical Ltd. is operating in the vicinity of a river since 20 years. A community living near X Chemical Ltd. claims that its operations has caused contamination of drinking water. X Chemical Ltd. has received notice from the governmental environmental agency that official investigations will be made into claims of pollution caused by the entity. If it is found that X Chemical Ltd. has caused contamination, then penalties and fine would be levied on it. X Chemical Ltd. believes that it has implemented all environmental safety measures to an extent that it is unlikely to cause pollution. Management is not sure whether it has all the information about the entire 20 years. Therefore, neither management nor external experts are able to assess X Chemical Ltd.'s responsibility until the investigation has completed. In such situation, how should management of X Chemical Ltd. account for a liability?
