I can speak to that from one perspective, and Colleen can speak from another.
On what we can and cannot do, we have different levels of approval for costs. Essentially, for us, the limit on what you can do to somebody's house is based on their health, safety, and security. We can build a ramp, and we have built a new bathroom on a main floor. There are a number of modifications--some of them quite significant--we have made to people's homes to allow them to live there for a subsequent number of years. From a cost-effective perspective, if you look at spending x number of dollars to create a bathroom on somebody's main floor and then look at the cost of institutionalization, it becomes a pretty good option.
We have different levels of approval, financially speaking. At a certain point it doesn't become cost-effective anymore, or you're trying to keep somebody at home and fundamentally jeopardizing their safety and security. They're not able to be at home anymore.
Would you like the details on the levels?
