Fed chairman Alan Greenspan's remarks that the weakening dollar isn't threatening the U.S. economic rebound failed to buoy the markets.

The services and consulting firm's share price fell $3.25 or 12.5%, to $22.66 after saying it expects earnings of 21 to 27 cents per share for the second quarter, making current analysts' forecasts look optimistic. That outlook excludes a charge of $75 million to $100 million related to real-estate consolidation.
