                         Supplement dated June 10, 2002
                      to Prospectus dated December 18, 2001

Revisions relating to the close of the n/i numeric investors Small Cap Value
Fund and the n/i numeric investors Micro Cap Fund

         The second, third and fourth paragraphs under the caption "Capital
Limitation" on page 2 of the prospectus are revised as follows:

     As a result, each of the Funds will close to further investment when
     increasing transaction costs begin to diminish the Fund's performance.
     Generally, when a Fund is closed to further investment, its shares are
     offered only to existing shareholders of the Fund and certain other
     persons, who generally are subject to cumulative, maximum purchase amounts,
     as follows: (i) persons who already hold shares of this Fund directly or
     through accounts maintained by brokers by arrangement with the Company,
     (ii) existing and future clients of financial advisors and planners whose
     clients already hold shares of this Fund, and (iii) employees of Numeric
     and their spouses and children. Other persons who are shareholders of other
     n/i numeric investors Funds are not permitted to acquire shares of a closed
     Fund by exchange. Distributions to all shareholders of the closed Fund will
     continue to be reinvested unless a shareholder has elected otherwise.

     Numeric reserves the right to reopen a closed Fund to new investments at
     any time or to further restrict sales of its shares.

     Currently, the n/i numeric investors Small Cap Value Fund is closed to new
     investments, subject to the general limitations described above. Numeric
     will close the n/i numeric investors Micro Cap Fund to new investments in
     accordance with the general limitations described above effective June 14,
     2002.

     Numeric intends to close the n/i numeric investors Growth Fund to new
     investors when the Fund's total assets reach $125 million, and intends to
     close the n/i numeric



     investors Mid Cap Fund when the Fund's total assets reach $200 million.
