Yes. In accordance with the internal audit standards, every year I have to have an internal quality review of the work that we do. This is done by a professional practices team in my function. Once every five years, we have to have an external review of the work that we do to make sure that we're following the standards.
What they will do is take a sample of some of the audits that we did and look at how we did our work, if we concluded against our objectives, if the team was independent and objective and whether the team had the proper training to do the work.
