The 170.0 pence deferred shares were created to facilitate a return of capital to shareholders following the reverse acquisition of United Utilities PLC by United Utilities Group PLC in the year ended 31 March 2009 (see company statement of changes in equity), and represent the amount of a special dividend paid on B shares at that time. The deferred shares convey no right to income, no right to vote and no appreciable right to participate in any surplus capital in the event of a winding up.
