[holding answer 8 June 2006]: The Accounts Payable (AP) module in Prism experienced various problems which prevented prompt closure for the months of December, January, February and March. These problems were identified and corrected. Changes have been made to Prism, and to our procedures, which came fully into effect at the end of March. We are now able to detect the errors which caused the problems within the month, enabling them to be corrected before the month-end. The AP module has closed promptly for April and May.
