Can a faculty endowment holder use funds to support professional work not within the scope of the endowment as defined by a donor agreement and/or BoR policies?

In limited circumstances, with substantial justification, and with donor and BoR permission, a faculty holder may use funds for professional work outside the endowment scope provided such expenditures are allowable (i.e., not supplantation, not for general discretionary use of the department). Such expenditures must be approved by all parties before any action is taken by the endowment holder or academic administration.
