There are a variety of reasons why this may happen.
First, it may be that the information was entered by the record company under an alternative title or name. Please try searching under alternative titles, names and spellings.
Second, the list does not contain any information related to products released in Canada prior to 2010.
Third, in the case of Group III items, it may be that no royalties are owed for the item or to the rightsowner in question. The portion of the settlement allocated to Low-Value Items will be paid to Class Members based on a market share allocation.
