NEW YORK (Standard&Poor's) Feb. 28, 2013--Standard&Poor's Ratings Services today assigned its rating to Illinois Finance Authority's $17.00 million adjustable-rate demand revenue bonds series 2013 (for the Steppenwolf Theatre Co. project) due March 1, 2043 (see list). The assigned rating reflects our opinion of the credit and liquidity support that The Northern Trust Co. ('AA-/A-1+') provides in the form of an irrevocable direct-pay letter of credit (LOC). Under the LOC, The Northern Trust Co. fully supports all bond payment obligations when the bonds are in the daily and weekly interest rate modes. Therefore, our rating applies only during these rate modes. If the bonds are converted to another rate mode, we will likely withdraw our rating. The
