The one thing that concerns us is that comfort letters are a good stop-gap measure, and we've identified them as something that users find helpful, but the issue is that if we continue for long periods of time using administrative means to administer tax legislation that really can only be changed by Parliament, it's a concern to us. We'd like to see this thing brought up to date and the use of comfort letters restricted to their original intent, which was to deal with situations that come up over the short term, and get the legislation updated rather quickly.
