            SCHEDULE I--CONDENSED FINANCIAL INFORMATION OF REGISTRANT
                      FOR THE YEAR ENDED DECEMBER 31, 2001

     Chicago Mercantile Exchange Holdings Inc., the registrant, has only one
asset, its investment in its wholly owned subsidiary, Chicago Mercantile
Exchange Inc., or CME, in the amount of $250,369,000 at December 31, 2001. Net
income from this investment on the equity basis of accounting amounted to
$68,302,000 for the year ended December 31, 2001. Net income is reflected as if
the registrant had been in existence for the entire year even though it was
formed during the year and became the parent of CME through a reorganization of
entities under common control as described in Note 1 to the financial statements
in Exhibit 13. The registrant has no liabilities, material contingencies or
guarantees. The registrant has received no cash dividends from CME.

     CME renewed its committed line of credit with a consortium of banks on
October 19, 2001. The line of credit is a secured credit facility in the amount
of $500.0 million. Under the terms of the credit agreement, CME is required to
maintain at all times a tangible net worth of not less than $90.0 million, which
is 35.9% of the net assets of CME.
