Recent Developments

    Our safety and soundness regulator, the Office of Federal Housing Enterprise Oversight (“OFHEO”), announced in July 2003 that it was conducting a special examination of our accounting policies and practices, and in September 2004 issued a preliminary report of its findings to date.  OFHEO subsequently identified additional accounting and internal control issues in February 2005, and issued its Report of the Special Examination of Fannie Mae (the “OFHEO Report”) on May 23, 2006.

    On December 22, 2004, we reported that the Audit Committee of our Board of Directors (the “Board”) had determined that our previously filed interim and audited financial statements and the independent auditor’s reports thereon for the period from January 2001 through the second quarter of 2004 should no longer be relied upon because such financial statements were prepared using accounting principles that did not comply with U.S. generally accepted accounting principles (“GAAP”).  We subsequently initiated an extensive restatement and re-audit of our financial statements with our new independent auditor, Deloitte & Touche LLP.

    On December 6, 2006, we filed our Annual Report on Form 10-K for the fiscal year ended December 31, 2004 (“2004 10-K”), which included consolidated financial statements for 2004 and a restatement of previously issued financial information for 2002, 2003, and the first two quarters of 2004.  Restatement adjustments relating to periods prior to January 1, 2002 are presented in our 2004 10-K as adjustments to retained earnings as of December 31, 2001.

    Our Board and management have initiated numerous internal and external reviews of our accounting processes and controls, our financial reporting processes, and our application of GAAP.   See “Risk Factors – Ongoing Internal and External Investigations” in our Offering Circular.  One of these external investigations was conducted by the law firm of Paul, Weiss, Rifkind, Wharton & Garrison LLP (“Paul Weiss”), under the direction of former U.S. Senator Warren Rudman.  On February 23, 2006, the Paul Weiss report to the Special Committee of the Board was publicly released, and included numerous findings about Fannie Mae’s accounting policies, practices and systems, compensation practices, corporate governance, and internal controls.  On February 24, 2006, we filed a Form 8-K with the U.S. Securities and Exchange Commission (the “SEC”) that includes the Paul Weiss report.

    The OFHEO Report presents OFHEO’s findings about Fannie Mae’s corporate culture, executive compensation programs, accounting policies and internal controls, internal and external auditors, senior management, and the Board.  In conjunction with the release of the OFHEO Report, Fannie Mae entered into settlement agreements with both OFHEO and the SEC on May 23, 2006.  The settlement agreements require Fannie Mae to pay civil penalties totaling $400 million.  In addition, the settlement agreement with OFHEO requires Fannie Mae to undertake certain remedial actions within a specified time frame to address the recommendations contained in the OFHEO Report, including an undertaking by Fannie Mae not to increase its “mortgage portfolio” assets except as permitted by a plan to be submitted by Fannie Mae for approval by OFHEO.  The settlement agreements constitute comprehensive settlements between Fannie Mae and both OFHEO and the SEC relating to the activities of Fannie Mae during the time period in question.  Please refer to our Form 8-K filed with the SEC on May 30, 2006 for further information about the OFHEO Report and the settlement agreements.  A complete copy of the OFHEO Report is available on OFHEO’s website at www.ofheo.gov.

    On July 20, 2006, the Federal Reserve Board implemented revisions to its payment systems risk policy requiring all government sponsored enterprises, including Fannie Mae, to fully fund their accounts with the Federal Reserve Banks before making payments to debt and mortgage-backed securities investors.  Fannie Mae complied with this policy by entering into various funding agreements with market participants.  In connection with this policy change, Fannie Mae also entered into a new fiscal agency agreement with the Federal Reserve Bank of New York.  In addition, Fannie Mae, as trustee for its mortgage-backed securities, invests collections on mortgage loans underlying our mortgage-backed securities in highly rated financial instruments, which may include Fannie Mae's senior debt securities or other debt securities if certain rating requirements are satisfied.

    On August 24, 2006, we announced that we had been advised by the United States Attorney’s Office for the District of Columbia that it was discontinuing its investigation of Fannie Mae’s accounting policies and practices, and did not plan to file charges against Fannie Mae.  Please refer to our Form 8-K filed with the SEC on August 24, 2006 for further information.

    We filed our 2004 10-K with the SEC on December 6, 2006.  We have not filed Quarterly Reports on Form 10-Q for the first, second and third quarters of 2005, or the first, second and third quarters of 2006, nor have we filed our Annual Reports on Form 10-K for the year ended December 31, 2005 or December 31, 2006.  See “Risk Factors – Lack of Financial Information about Fannie Mae” in our Offering Circular.

    Form 8-Ks that we file with the SEC prior to the completion of the offering of the Notes are incorporated by reference in the Offering Circular.  This means that we are disclosing information to you by referring you to those documents. You should refer to “Additional Information about Fannie Mae” in the Offering Circular for further details on the information that we incorporate by reference in the Offering Circular and where to find it.
