From the UNT PI Handbook:

Occasionally, a project's financial resources need to be reallocated due to the nature and progress of the research. For example, a piece of equipment may become unnecessary, while another expense becomes necessary, or the scope of the project might change due to unforeseen circumstances. In these cases, re-budgeting may be required.

Re-budgeting will be allowed only to the extent the terms of the award or contract allow it. Therefore, before any attempt to re-budget, the PI should review the terms of the specific award. The PI should also assess the potential impacts of the proposed re-budgeting (e.g., shifting an expense from one budget category to another or shifting expenses from direct costs which may result in adjustment to the F&A cost collection). Depending on the terms of the agreement, re-budgeting may require sponsor approval.

Speak with Rochelle Sykes to discuss your options if you think you need to rebudget between budget categories, including any potential impact to F&A. If prior approval is needed, you will obtain that in writing (email) from your program officer or sponsor. Rochelle will then assist you with an Award Modification Approval Form to be submitted with OGCA.
