Mr. Robert Watt:

We absolutely share the Senator's concerns fully and are as concerned as he or anybody else would be to hear those allegations and ethical issues. More than ethical issues were raised. Much more fundamental issues than that were raised but, of course, we are concerned about issues of an ethical nature. We will review our practices and how we share data, and our overall approach, in light of what was said. My colleague, Dr. MacLellan, wishes to come in to add to that.
