The Division, with the Department of Labor, will calculate the annual fair share contribution. The formula is based on the private sector liability for the uncompensated care pool (“UCP”) and calculates the portion of the private sector liability that can be attributed to employers that do not meet the “fair and reasonable” premium contribution. The Division will also calculate how many UCP funds were actually used by non-elderly, uninsured Massachusetts residents, then come up with the per employee cost of uncompensated care. The sum of these two calculations is the annual “fair share contribution.”
