             Supplement to prospectus dated September 23, 1999

The following paragraph replaces paragraph number 10 on page
vi of the Prospectus:

If one or more stocks are selected by both Processes One and
Two, it will be counted as one selection only.  As a result,
to get to a total of 50 stocks, additional stocks will be
identified and selected by alternately applying Process One
to arrive at another stock and then Process Two to arrive at
another stock, continuing as necessary to get to 50 stocks.
The 50 stocks are approximately equally dollar weighted.
