cash dividend last  year, which  delivered approximately $350  million to  our 
shareholders, or  consistently demonstrating  admirable corporate  stewardship 
through consistent, prudent  financial management, Bill's  positive impact  on 
our company has been  substantial, and we are  delighted that he has  received 
this well-earned recognition from FEI," said William Noglows, Chairman and CEO
