GLOBAL NOTES AND STATEMENT OF LIMITATIONS, METHODOLOGY, AND

DISCLAIMER REGARDING THE MONTHLY OPERATING REPORT OF

MF GLOBAL HOLDINGS LTD. AND ITS AFFILIATED DEBTORS

The Monthly Operating Report filed by MF Global Holdings, Ltd. (“Holdings Ltd”) and its affiliated debtor, MF Global Finance USA, Inc., in these jointly administered chapter 11 cases (collectively, the “Debtors”) is limited in scope, covers a limited time period and has been prepared by the Debtors with the assistance of its advisors solely for the purpose of complying with the reporting requirements of the Bankruptcy Court and title 11 of the United States Code (the “Bankruptcy Code”). The financial information contained in the Monthly Operating Report, is preliminary and unaudited, and as such may be subject to revision. The information in the Monthly Operating Report should not be viewed as indicative of future results.

At the time of its bankruptcy filing, Holdings Ltd and its subsidiaries and affiliates (“the Company”) was one of the world’s leading brokers in markets for commodities and listed derivatives. The Company provided its customers access to more than 70 exchanges globally, and was a leader by volume on many of the world’s largest derivative exchanges. The Company was also an active broker-dealer in markets for commodities, fixed income securities, equities and foreign exchange. The Company was one of 22 primary dealers authorized to trade U.S. government securities with the Federal Reserve Bank of New York (the “Federal Reserve”). In addition to executing client transactions, the Company provided research and market commentary to help clients make trading decisions, as well as provided clearing and settlement services. The Company was also active in providing client financing and securities lending services.

The Company, headquartered in the United States had operations globally, including the United Kingdom, Australia, Singapore, India, Canada, Hong Kong, and Japan. The Company’s priority was serving the needs of its diversified global client base, which included a wide range of institutional asset managers and hedge funds, professional traders, corporations, sovereign entities and financial institutions. The Company also offered a range of services for individual traders and introducing brokers. As of the petition date the Company had approximately 2,870 employees worldwide, 13 of which were employed by the Debtors in the United States. The Company derived revenues from three main sources: (a) commissions generated from execution and clearing services; (b) principal transactions revenue, generated both from client facilitation and proprietary activities; and, (c) net interest income from cash balances in client accounts maintained to meet margin requirements, as well as interest related to the Company’s collateralized financing arrangements and principal transactions activities.

As a result of the bankruptcy filing, certain MF Global subsidiaries and affiliates became subject to various proceedings, in which administrators or trustees were appointed by the requisite authorities to oversee, manage and administer the affairs of these entities going forward. Holdings Ltd is a holding company, and it relies on the resources of its various subsidiaries and affiliates to complete their month end closing procedures, finalize their respective books and records and provide Holdings Ltd with the necessary information to finalize its own books and records. In addition, these subsidiaries provide Holdings Ltd with various services and resources that it relies upon to close its own books and records. Since the bankruptcy filing, these subsidiaries and affiliated entities have not provided Holdings Ltd with the required financial and accounting information or the access to certain systems that are necessary to enable the Debtors to close their books and records. The Debtors have been in constant contact with the various representatives of the administrators and trustees to establish an information sharing protocol which could provide Holdings Ltd with the requisite information and resources to close its books. Since this protocol has not been fully agreed to or established at the time of this filing, and Holdings Ltd has not received the required information from its subsidiaries and affiliates, the Debtors have been unable to complete the month-end close process for October 31, 2011 and as a result the financial statements and other financial information as of the petition date or December 31, 2011 are not yet available. The Debtors intend to complete the month-end accounting close procedures and prepare financial statements, but require significant cooperation from the local trustees and administrators

who are now in charge of the various MF Global subsidiaries and affiliated companies to do so. Further, the Debtors intend to amend this Monthly Operating Report with the relevant financial information when the financial statements are prepared, but at this time the Debtors are unable to estimate when that will occur.

In preparing this Monthly Operating Report, the Debtors relied upon bank statements, flows of funds and other relevant and available financial information for the period of 12/1/11 through 12/31/11. While the Debtors have exercised their best efforts to ensure that the Monthly Operating Report is accurate, based on limited information that was available at the time of preparation, inadvertent errors or omissions may exist. The Debtors reserve the right to amend the Monthly Operating Report from time to time as may be necessary or appropriate.

On December 19, 2011, MF Global Capital LLC, MF Global FX Clear LLC, and MF Global Market Services LLC, (collectively “the New Debtors”), each filed a voluntary petition for relief under chapter 11 of Title 11 of the United States Code in the United States Bankruptcy Court for the Southern District of New York. The chapter 11 cases have been assigned to the Honorable Judge Martin Glenn and are being jointly administered under the caption “In re MF Global Holdings, Ltd., et al.” Case No. 11-15059 (MG). Financial information related to MF Global Capital LLC, MF Global FX Clear LLC, and MF Global Market Services LLC for the period 12/19/11 through 12/31/11 has not be included herein. The January 2012 monthly operating report will be modified to incorporate all necessary information related to these additional debtors.

From the petition date through December 31, 2011, the New Debtors did not make any cash disbursements.
