NEW YORK (Standard&Poor's) Dec. 3, 2012--Standard&Poor's Ratings Services today raised its rating on Illinois Finance Authority (formerly Illinois Development Finance Authority)'s $6.75 mil variable-rate demand multifamily housing revenue bonds series 1999 (for the Butterfield Creek Associates L.P. project) due April 1, 2039, to 'AA+/A-1+' from 'A/A-1' following the addition of a confirming letter of credit (CLOC) from Federal Home Loan Bank of Atlanta (FHLB Atlanta; 'AA+/A-1+'). The 'AA+/A-1+' rating reflects the higher of our rating on Bank of America N.A. ('A/A-1'), the fronting LOC (FLOC) provider, and our rating on FHLB Atlana, the CLOC provider. Under their respective LOCs, each bank fully supports repayment when the bonds are in the weekly or monthly interest rate reset
