NEW YORK (Standard&Poor's) May 6, 2014--Standard&Poor's Ratings Services today assigned its 'BBB' senior unsecured debt rating to Eastman Chemical Co.'s proposed offering of $500 million of senior unsecured notes due 2044. All our other ratings on Eastman, including the 'BBB' corporate credit and 'A-2' commercial paper ratings, remain unchanged. The outlook is stable. Eastman expects to use the net proceeds of this offering for general corporate purposes, which may include working capital, capital expenditures, the repayment of indebtedness outstanding from time to time and other matters in connection with the implementation of its strategic initiatives. We expect the company may use a portion of the net proceeds to acquire or invest in businesses, products, and technologies
