The Board has many powers and functions, including investing the Plan's assets, interpreting Plan provisions, amending the Plan, deciding policy questions, determining benefit program options (e.g., insured or self-funded, HMO or PPO) and contracting with service providers such as consultants, auditors, attorneys and investment managers. The Board is the named fiduciary of the Plan with the sole authority to control and manage the Plan's administration. The Board is authorized to interpret the Plan, and only its authorized agents (such as EISB) may otherwise act on its behalf. The Board has the sole ultimate discretionary authority to determine eligibility for benefits, adopt and apply such rules of administration as it deems appropriate, and construe the terms of the Plan and other related documents. Neither an individual Trustee, Local 6, a Local 6 representative, SFECA, an Employer, nor any Employer representative, is authorized to interpret the Plan or act on behalf of the Board. The rules, interpretations, computations and actions of the Board shall be binding and conclusive on all persons.
