The rating on the 2009 series E-1 and E-2 is based on the joint support of irrevocable, direct-pay letters of credit (LOCs) provided by JPMorgan Chase N.A. (AA-/A-1+) and the pledged support of the University of Chicago Medical Center, which maintains a Standard&Poor's underlying rating (SPUR) of AA-/Negative. The rating on the 2009 series D-1 and D-2 is based on the joint support of irrevocable, direct-pay letters of credit (LOCs) provided by Bank of America N.A. (A+/A-1)
