The stipend is not to be used as a replacement for any part of the PI’s salary at the institution. It can be processed in your financial system as salary but the researcher must receive the full stipend in addition to their full university salary. In addition, many university financial systems require that fringe benefits be paid on ALL compensation. If that is the case, the fringe benefits incurred as a result of the stipend must be paid from the stipend. On your budget submitted to the NLN, the $2500 should be listed as a stipend and the amount paid as fringe benefits should be noted and subtracted from the stipend.
