NEW YORK (Standard&Poor's) Nov. 20, 2007--Standard&Poor's Ratings Services said today it revised its outlook on Office Depot Inc. to negative from stable. At the same time, we affirmed the 'BBB-' corporate credit and senior unsecured ratings. "While the company has good liquidity and is up to date with its financial filing requirements," said Standard&Poor's credit analyst Stella Kapur, "recent operating performance has been weaker than anticipated." Additionally, we anticipate debt leverage will deteriorate to around 3.1x by the end of the year, which will be weak for current ratings.
