OMB Circular A-21 and OMB Circular A-110 also provides for federal agencies to allow for rebudgeting of funds under certain conditions without agency approval. These actions may be done internally with review and concurrence of RSP unless prohibited by specific agency or award guidelines which prohibit it. Some conditions which prohibit internal approval and require agency authorization include

1. Change in the scope or the objective of the project or program (even if there is no associated budget revision requiring prior written approval).
2. Change in a key person specified in the application or award document.
3. The absence for more than three months, or a 25 percent reduction in time devoted to the project, by the approved project director or Principal Investigator (PI).
4. The need for additional federal funding.
5. The transfer of amounts budgeted for indirect costs to absorb increases in direct costs, or vice versa, if approval is required by the federal awarding agency.
