We have a fairly rigorous procedure for conflict of interest. As you can imagine, many of our auditors are privileged to sensitive information affecting companies that are listed on stock exchanges, grants that would be given to them, loans, financial information, those sorts of things. All of our staff must declare every year; they are required to fill out a form about conflicts of interest, generally as to whether they have family members working in senior positions in government. More importantly, they also have to disclose all of their financial holdings to a designated person within the office. In certain cases we have had to set up blind trusts for certain of our senior employees who are working on audits, for example, of the Office of the Superintendent of Financial Institutions, those sorts of things. So there is quite a rigorous process.
Obviously I come from a world of accounting firms, where the list of prohibited investments was almost a volume. We haven't gone that far to prohibit staff from investing, but certainly we do make sure they generally are aware of all that. Again, on each individual audit, every member of the audit team—and this is a professional standard—must have a declaration of independence, and that has to be for every single audit we undertake. There is a very rigorous process, not only within the office but with professional standards as well.
