My understanding is that the risk profile is the distribution of possible outcomes (it does not have to be just assets - liabilities = free reserves, it can be gross loss, net loss, ... anything really).
The risk measure in this example is the financial value of the 99.5% VaR.
The risk tolerance is therefore the maximum amount they are willing for this value to be.
For example, the 99.5% VaR of net loss under a particular set of mitigation techniques is GBP1bn, but the company may only have a risk tolerance of GBP800m. Therefore the mitigation techniques need to be adapted/added to in order to reduce the GBP1bn down to at most GBP800m.
But I'm still studying the course so maybe one of the ActEd guru's could confirm!
edit: I've done a bit more reading around the topic and seems my interpretation wasn't correct - the tolerance is indeed the level of confidence (i.e. 99.5% in this example).
