NY -- Standard&Poor's CreditWire 12/24/97 -- NY -- Standard&Poor's CreditWire 12/24/97 -- Standard&Poor's today assigned its triple-'B' rating to Illinois Development Finance Authority's revenue bonds series 1997C, issued for Community Rehabilitation Providers Facilities Acquisition Program. Additionally, Standard&Poor's affirmed its triple-'B' rating on the authority's revenue bonds series 1997A and 1997B, issued for Community Rehabilitation Providers Facilities Acquisition Program. The rating reflects the strengths of the pool structure, including: -- Overcollateralization through a special reserve fund; -- Mortgages on property acquired or refinanced by the bonds and a pledge of each provider's gross revenues and debt service reserve fund (DSRF); -- State intercept mechanism to support both debt service payments and DSRF replenishment;
