So, I'm sure members of this Committee have heard this on several occasions as we've introduced the system, but we have had to put in a fairly complex and detailed system of assessing people's needs, producing care packages to meet those needs, offering choice to those people, and responding to that choice, then doing what the D S S used to do, I E, a financial assessment of their ability to meet the costs of that care, and settling our contribution, and we're involved therefore in contracting with the independent sector for purchase of that care, and with the collection of contributions from those individuals, with increasing numbers and increasing complexity.
