Each Trustee who is not an employee, officer or director of Natixis Advisors, the Distributor or their affiliates also receives a meeting attendance fee of $10,000 for each meeting of the Board that he or she attends in person and $5,000 for each meeting of the Board that he or she attends telephonically.
