The increase in the year and the quarter includes an increase of approximately 3% and 4%, respectively, attributable to one of our broker/dealer businesses, and both periods include a 2% positive impact of foreign exchange movements overall and within each of our segments. Adjusting for these items, organic revenue growth in the year and the quarter was 6% and 8%, respectively. The broker/dealer revenue is uncharacteristically high and is expected to return to former levels over time.
CristÃ³bal Conde, president and chief executive officer, commented, âSunGardâs performance for the quarter was strong despite uncertainty about the broader economy. In our Financial Systems business, fourth quarter results were very strong and were not impacted by the sub-prime crisis. In our Higher Education and Public Sector businesses, we continued to sign new business and renew existing relationships. We saw continued strong performance from our Higher Education business for the quarter and the year. We will begin reporting these businesses separately going forward. In our Availability Services business, we saw a continuation of the trend towards advanced recovery and managed services. Our Availability Services business in the UK produced strong results. Overall, our competitive position is stronger than ever and our pipelines remain healthy.â
