forth certain statistical data based thereon. In addition, there are a number of
other changes from the Prospectus as originally filed to which reference is
made, including the increase in the size of the Fund, a corresponding increase
in the number of Units and a change in the individual trusts constituting the
Fund. All references to the Units, prices and related statistical data will
