Health Benefit Fund Reserve. The parties agree that a portion of the funds available within the Employee Health Benefit Fund shall be maintained as a reserve to ensure the payment of health benefit related expenditures. Accordingly, the parties commit to continuing to work together in conjunction with the IAFF and FOP, to enact a policy to maintain a reserve fund balance which shall be used exclusively for health benefits. Should the policy not be agreed to by January 2021, the agreement shall be reopened on this section and subject to the impasse resolution procedures in the County Collective Bargaining Law.
