NEW YORK (Standard&Poor's) Jan. 28, 2013--Standard&Poor's Ratings Services today affirmed its 'AAA/A-1+' rating on Power County Industrial Development Corp.'s $20 million tax-exempt adjustable mode facilities revenue bonds Series 2001 (for the FMC Corp. project) due April 1, 2014. The long-term component of the rating is based on our long-term issuer credit ratings on--as well as the joint support provided by--Wells Fargo Bank N.A. (AA-), the letter-of-credit (LOC) provider, and FMC Corp. (A-), the obligor, assuming a low correlation between the two entities. The short-term component of the rating reflects only our short-term issuer credit rating on Wells Fargo Bank N.A. (A-1+) because we currently do not assign a short-term rating to FMC Corp. On Dec. 17,
