Thank you, Mr. Chairman. Thank you for the presentations today as well.
There have been a number of great examples that you've provided I think in regard to the success of these programs. There are costs that are variable depending on a number of factors that go into each one of them. So without getting into the monetary amounts, what drives the costs up so much? It's hard to believe that it could be expensive for every individual enrolled. So out of all the projects that have run their course, can you provide me with some examples of the benefits of the ones that have succeeded and some of the failures?
