For the fiscal year ending June 30, 2014, and for each fiscal year thereafter, the Comptroller shall fund the fringe benefit cost differential between the average rate for fringe benefits for employees of private hospitals in the state and the fringe benefit rate for employees of The University of Connecticut Health Center from the resources appropriated for State Comptroller-Fringe Benefits in an amount not to exceed $13,500,000. For purposes of this section, the “fringe benefit cost differential” means the difference between the state fringe benefit rate calculated on The University of Connecticut Health Center payroll and the average member fringe benefit rate of all Connecticut acute care hospitals as contained in the annual reports submitted to the Health Systems Planning Unit of the Office of Health Strategy pursuant to § 19a-644.
