My award does not reference the cost share commitment in the budget/budget justification, does it need to be tracked?

Yes. Upon receipt of an award based on a proposal that included voluntary cost sharing in the budget or budget justification (whether or not the agency explicitly calls out the cost sharing), the cost sharing becomes "committed" and an obligation that is subject to audit and must be fulfilled.

Do any sponsors or programs prohibit voluntary committed cost share?

Yes. For example, as a policy, the National Science Foundation (NSF) prohibits Voluntary Committed Cost Sharing. NSF policy further states that resources not included in the Budget or Budget Justification should be listed in the Facilities, Equipment, and Other Resources section, but should not contain “quantifiable financial information” for those resources.

Why is the university concerned with excessive cost share?

The university is required to provide the stated resources that are committed as Cost Sharing in a proposal, whether the commitment of resources is Mandatory Committed Cost Sharing or Voluntary Committed Cost Sharing. Excessive or unnecessary cost share limits the university’s capacity to commit resources when required for eligibility of submission, increases our administrative burden, and reduces the availability of resources for other purposes.
