I'll let Martin go through some details, but really what we're trying to do is test on an ongoing basis how we are carrying out work. We have to test a number of things. These aren't just financial audits. They are health and safety audits, which are extremely important to us. We need to be able to keep our people, our subcontractors, our building occupants, and everyone who uses the building safe, so that is an area of audit.
We have eight contracts across the country. We would typically spread out audits across those eight contracts. We do project audits. We do value-for-money audits. We really try to test each of the individual contracts to make sure they're performing as we expect them to.
