1) BASIS OF PRESENTATION

The Condensed Consolidated Balance Sheet as of September 30, 2011, the Condensed Consolidated Statements of Operations for the three- and nine-month periods ended September 30, 2011 and 2010, and the Condensed Consolidated Statements of Cash Flows for the nine-month periods ended September 30, 2011 and 2010 of DUSA Pharmaceuticals, Inc. (the “Company” or “DUSA”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). These condensed consolidated financial statements are unaudited but include all normal recurring adjustments, which management of the Company believes to be necessary for fair presentation of the periods presented. The results of the Company’s operations for any interim period are not necessarily indicative of the results of the Company’s operations for any other interim period or for a full year.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2010 filed with the Securities and Exchange Commission. The Condensed Consolidated Balance Sheet as of December 31, 2010 included herein was derived from the audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require disclosure. Subsequent events have been evaluated through the date of issuance of these financial statements.
