Thank you for your question.
The first thing you can see, if you have your table of program expenditures in front of you, is that the number of clients rose quite significantly. It went from 71,000 clients in 2000-2001 to 128,000 clients in 2009-2010.
We don't have the number, but there has also been an increase in the number of claims per client. Then there is the complexity of the services and the increase in the cost of services. So there is a set of factors that mean that costs have risen, by a fairly significant amount in fact.
