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 have subsequently initiated an extensive restatement and re-audit of our financial statements with our new independent auditor, Deloitte & Touche LLP.  We anticipate that the impact of the restatement will be material to Fannie Mae’s financial statements for many, if not all, of the periods involved.

    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.  Investigations into our accounting policies and practices and our financial reporting continue with the U.S. Attorney’s Office for the District of Columbia.  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.

    We have not filed Quarterly Reports on Form 10-Q for the third quarter of 2004, the first, second and third quarters of 2005, or the first quarter of 2006, nor have we filed our Annual Reports on Form 10-K for the years ended December 31, 2004 or December 31, 2005.  As we most recently reported in a Current Report on Form 8-K filed with the SEC on May 9, 2006, we estimate that it is unlikely we will complete our Annual Report on Form 10-K for the year ended December 31, 2004, which will include our restated results, prior to the second half of 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.
