Allegis, parent of United Airlines, agreed to prepay a $700-million convertible note issued by Boeing earlier this year to help defend Allegis from a takeover. The note, convertible into Allegis common or a new series of preferred stock, was issued as part of a $2.1-billion order for Boeing jets by United. Boeing said Allegis would have to repay the note plus $50 million in interest by Jan. 5. Since the note was issued in May, Allegis has reduced the takeover threat by selling major portions of the company.
