Thank you, Mr. Chair. So these are demand -- this is demand driven as I understand it. So I can start one at a time.
We've got the referred diagnostic laboratory services. That is a funding shortfall to the laboratory services that we are under contract. So we send materials for testing to Dynalife Medical Labs, and it's a multi-year contract. They're set fees. If our usage goes up, then we have to pay more.
Under chemotherapy drugs, similarly, Mr. Chair, if we wind up having a greater uptake or greater usage of those -- or a need, then the costing will, again, go up.
And similarly, radiology services, we have an external contract with an entity that provides those services and, again, it's on an if-and-when basis. If usage goes up then, again, we are in a situation where we are required under that contract to pay more. Thank you.
