NEW YORK (Standard&Poor's CreditWire) March 31, 1999—Standard&Poor's today assigned its triple-'B' rating to Illinois Development Finance Authority's $15.45 million revenue bonds series 1999, issued for Community Rehabilitation Providers Facilities Acquisition Program. The bonds are scheduled to sell the week of April 5, 1999. Standard&Poor's also affirmed its triple-'B' rating on the authority's $87.19 million revenue bonds, issued for the program. The rating reflects: -- The strengths of the pool structure, including over-collateralization 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;
