The U.S. government recently increased its borrowing capacity under the federal debt ceiling. However, there continues to be a perceived risk of a sovereign credit ratings downgrade of the U.S. government, including the ratings of U.S. Treasury securities. In July 2011, Moody’s Investors Service, Inc. (Moody’s) placed the U.S. government under review for a possible credit rating downgrade, and on August 2, 2011 it confirmed the U.S. government’s existing sovereign rating, but stated that the U.S. government’s rating outlook is negative. Also in July 2011 Standard & Poor’s Financial Services LLC (S&P) placed its sovereign credit ratings of the U.S. government on CreditWatch with negative implications. On August 2, 2011 Fitch, Inc. (Fitch) affirmed its existing sovereign rating of the U.S. government, but stated that the rating is under review. A downgrade of U.S. sovereign credit ratings could correspondingly impact the credit ratings of instruments issued, insured or guaranteed by institutions, agencies or instrumentalities directly linked to the U.S. government. We cannot predict if, when or how any changes to the credit ratings of these organizations will affect economic conditions or the resulting impact on the Corporation. Such ratings actions could result in a significant adverse impact to the Corporation.
