NewsCorp's Fox licensing unit is responsible for sourcing consumer goods related to characters from animated Fox movies and TV shows like The Simpsons. 

We have had one meeting with the company and they acknowledge their responsibility to monitor their supply chain and agreed to look into whether their licensees were doing monitoring.  The company does not appear to have been actively monitoring supply chain compliance issues.  Some of their licensees are major toy companies like Hasbro and Mattel, who already have monitoring programs.
