ORS receives its budget from three sources. The Management Fund is an annual assessment to the Institutes and Centers (ICs) where the benefit cannot be attributed to an individual user (for example, fire and rescue, police, emergency management). Management Fund assessment factors use a combination of local census, local space, campus census, and campus space. The Service and Supply Fund Assessment is a quarterly tap to the ICs where the benefit can be attributed to an individual user (for example, library services, radiation safety services, interpreting, international services). The Service and Supply Fund Fee for Service is a direct sales transaction for goods or services (for example, photography, graphic design, equipment rental, animal health surveillance).
