That does imply strongly a fiduciary relationship but the relationship legally is to the corporation, which in this case is the Board as opposed to the board of directors; however, the beneficiaries here are the ones to whom you owe the allegiance and responsibility and duty of care.
Cela implique certes une grande responsabilité fiduciaire, mais envers la société, en l'occurrence l'office; cependant, ici, c'est envers les bénéficiaires que doit s'exercer l'allégeance et la responsabilité et la diligence.
