Standard&Poor's Ratings Services has affirmed its 'AA/A-1' rating on Michigan State Hospital Finance Authority's (Trinity Health) variable-rate revenue bonds (Trinity Health Care Credit Group) bonds series 2000E in conjunction with the proposed first amendment to the standby bond purchase agreement (SBPA) provided by Comerica Bank (A-1) on May 30, 2008. The amendment will revise the automatic termination events of the SBPA. However, these amendments will have no impact on the rating of the bonds.
