NEW YORK (Standard&Poor's) Feb. 28, 2008--Standard&Poor's Ratings Services said today it assigned its 'A' senior unsecured rating to Archer Daniels Midland Co.'s (ADM) $700 million senior unsecured notes due 2018, a drawdown from the company's unlimited Rule 415 shelf registration. At the same time, Standard&Poor's affirmed its 'A' long-term and 'A-1' short-term corporate credit ratings on the Decatur, Ill.-based company. The outlook is stable. "We expect that proceeds of the notes will be used for repaying short-term debt originally incurred for meeting the company's increased working capital needs," said Standard&Poor's credit analyst Jayne M. Ross. The ratings on ADM are supported by its position as one of the world's leading agribusiness companies,
