ITEM 6 - FINANCIAL STATEMENTS AND EXHIBITS

Note :   As noted in the U9C3 filing for the quarter ended June 30, 2001, upon the acquisition of Allegheny Energy Global Markets, LLC (Global Markets), it was the intent of Allegheny Energy, Inc. (Allegheny Energy) and Allegheny Energy Supply Company, LLC, (Supply) that (1) all trading activity effected by Supply directly or by Global Markets as agent for Supply from the closing of the acquisition ("Post-Closing Trades") be done for the account of Supply and recorded solely on the financial records of Supply (and not Global Markets), (2) the closing acquired trades be acquired for the account of Supply and be recorded solely on the financial records of Supply (and not Global Markets), and (3) the novated trades be purchased by Supply from Global Markets on the date of novation for the net fair market value (positive or negative) of such trades as of such date. However, due to an accounting error prior to the filing of the U-9C-3 form on November 29, 2001, certain accounting entries did not conform to the parties intentions. In order that the accounting entries conform to the above, Allegheny Energy revised the stand-alone financial statements of Global Markets and Supply. The adjustments did not alter the consolidated financial results of Supply.
