English to Arabic Law/Patents Law: Contract(s) agreement

Assignments to members of governing bodies of the parties‎
Members of the Governing bodies of the Parties shall not be remunerated. Any cost incurred for involvement in Programme related activities (Board meetings, visits to Programme activities, participating in events, workshops, visits, etc.) will be covered by the Programme or be reimbursed against receipted expense claims.


I cannot get what assignments really mean in this context.
