Mr. Pat Maher:

It will be a technical audit of the system to determine how this particular arose. The problem was intermittent. It affected approximately 5% of re-entrant customers. Had it been universal, in terms of re-entrant customers using a tag system - obviously cash customers were not affected - it would have been picked up on sooner. We monitor the monthly reports etc.. The change in terms of the figures that we had arising from that 5% versus the normal fluctuations in terms of income is quite difficult to pick up. The issue has arisen and we have to deal with it and we are dealing with it.
