Operations and Administration expenses for 2003/2004 were higher than previous year primarily due to one-time expenditures related to the implementation of IT projects ($7 million), increased employee future benefit costs (primarily pension costs of $8 million), costs for regulatory activities including preparation and submission of revenue requirement application ($8 million) and a provision for the GSX project ($22 million). The increase in costs was partly offset by reduced legal and associated costs incurred by Powerex arising from claims related to the electricity wholesale market in California ($20 million). Maintenance expenditures were higher than previous year primarily due to maintenance performed as a result of forest fire damage and system restoration due to storms.
