ITEM 8.01 OTHER EVENTS.

     Arden Realty, Inc. (the “Registrant”) is re-issuing in an updated format its historical financial statements in connection with Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS 144”). During the fiscal year ended December 31, 2004, the Registrant sold properties and in compliance with SFAS 144 has reported revenue, expenses and net gains from the sale of these properties as discontinued operations for each period presented (including the comparable periods of the prior year). Under SEC requirements, the same reclassification as discontinued operations required by SFAS 144 following the sale of a property is required for previously issued annual financial statements for each of the three years shown in the Registrant’s last annual report on Form 10-K, if those financials are incorporated by reference in subsequent filings with the SEC made under the Securities Act of 1933, as amended, even though those financial statements relate to periods prior to the date of the sale. This reclassification has no effect on the Registrant’s reported net income available to common shareholders or funds from operations.

     This Report on Form 8-K updates Items 6, 7, 8 and 15 of Registrant’s 2003 Form 10-K to reflect the properties sold during the fiscal year ended December 31, 2004 and the property held for disposition at December 31, 2004 as discontinued operations. All other items of the Form 10-K remain unchanged. No attempt has been made to update matters in the Form 10-K except to the extent expressly provided above.
