Yes, I'm happy to speak specifically about some of the policies. For obvious reasons, we won't speak to the details of operational physical security measures.
I would point, for example, to the review of all collaboration agreements by a science security committee, in addition to the investigators and the lab management. I would point to enhanced compliance monitoring from our security branch. As well, we have partnerships with our security and law enforcement agencies. I would point to the mandatory requirement for not just conflict of interest but affiliation declarations, the access control systems and the new student policies that require appropriate clearances.
