Mr. Seamus McCarthy:

On the relative cost, from discussions we have had in the office, we have found that there has been quite significant variation over the years. This is true when we contract out audits as well. The price can vary from year to year, depending on how busy potential contractors are. If they have more scope, they are willing to price very competitively, and in that instance it can represent good value. It is hard to get a long-term value for money comparison done. It varies.
