Our ability to finance working capital needs, capital expenditures and general corporate needs from the public and private markets, as well as the associated cost of funding is dependent, in part, on our credit ratings. During 2010, in conjunction with the Amendment of the Bank Credit Agreement, the 8.375% Notes issuance, and the 6.0% and 8.0% Notes tenders, both Moody’s Investor Services (Moody’s) and Standard & Poor’s Ratings Services (S&P) raised our credit ratings. The 6.0% Notes are not rated. As of the filing date, our credit ratings, as assigned by Moody’s and S&P were:

(a) The 3.0% Notes have not been rated by Moody’s; this rating reflects the rating for the 4.875% Notes. 

(b) The 4.875% Notes have not been rated by S&P; this rating reflects the rating for the 3.0% Notes. 

There can be no assurance that our credit ratings will remain at these levels or will not be downgraded in the future, in some cases for reasons beyond our control.
