"The combination of RSW’s 40-year track record of serving clients in the Canadian infrastructure and energy markets and the work of its talented staff on complex projects in more than 50 countries further strengthens AECOM’s ability to win the world’s most complex and demanding projects."

RSW generated approximately $45 million of gross revenue in the 12 months ending Nov. 30, 2009. AECOM expects the transaction to be accretive to cash earnings per share (EPS) in fiscal year 2011. On a GAAP basis, the transaction is expected to be neutral to EPS in fiscal year 2011.
