I'll try to address that question.
To begin with, very quickly, as part of our regular business we conduct about 400,000 investigations a year across the statutory programs—employment insurance as well as the pension programs. In addition to that, over the last few months we have undertaken a very targeted and special EI stewardship review. What we're trying to do there is improve our understanding of what the root causes are of overpayments. What lies behind errors that get made, abuse, and fraud? With the results of that review, once it is finished, we hope to fine-tune the approaches we take to investigations on an ongoing basis.
There are other things we are doing to improve our ability to detect and prevent. We regularly run training and retraining programs of our employees who work in these areas. A lot of this work is about data matching and lining up reports we receive from employers with those we receive from workers. There's constant improvement in the techniques we use in that data matching. We work with clients, through information sessions, so they understand the rules of calculations of benefits and they understand the information they are required to provide for us. We have payment accuracy and processing accuracy monitoring that's going on, on an ongoing basis as well. Those are some of the things that I would suggest we are doing to respond to improve that capacity in detecting and preventing errors and overpayments.
