In the contracts that we looked at, we did look at what mechanisms they put in place. Normally there are many checks and balances, as I mentioned earlier, that help reduce the risk around a procurement: ethical ones, integrity ones and financial viability; there's a risk assessment.
Not all of them were done in these instances. We were able to look at the ones that were done. We did not look at the ethical, because it was not one of the measures that was addressed in some of the contracts we reviewed.
