Item 4.02    Non-Reliance on Previously Issued Financial Statements or a Related
Audit Report or Completed Interim Review

         Alleghany Corporation (the "Company") has determined that its financial
statements for the year-ended December 31, 2001, included in its Annual Report
on Form 10-K for the year-ended December 31, 2003, incorrectly classified net
gain on sale of subsidiaries as part of revenues from continuing operations. The
error in classification of net gain on sale of subsidiaries in 2001 has no
effect on the Company's net earnings for 2001 or on any balance sheet items. The
error will be corrected in the Selected Financial Data to be included in the
Company's Annual Report on Form 10-K for the year-ended December 31, 2004, by
restating such 2001 net gain on sale of subsidiaries to discontinued operations.
Although the presentation was an error, the Company believes that its various
public disclosures regarding its 2001 results fully disclosed the relevant
transactions and the accounting therefor. Nevertheless, after consultation with
the Chairman of the Company's Audit Committee and KPMG LLP, the Company's
independent registered public accounting firm, the Company determined on
February 8, 2005 that investors should not rely on the Company's consolidated
financial statements for the year-ended December 31, 2001 with respect to the
error described herein.
