Cost sharing is that portion of total project costs that are paid from sources other than the sponsor. Typically, cost sharing is a concept that is used by some federal agencies to demonstrate to Congress and others a recipient's willingness to share in the project's expenses. Some agencies make a distinction between "cost sharing," "in-kind" and "matching." Generally, all these terms refer to the share of costs not charged to the sponsor. A cost share can include cash contributions, donated services or facilities.
If your funding source requires cost sharing, consult with the Development Office as early as possible in the proposal development process.
Mandatory cost sharing represents expenses that are paid from non-federal funds that are required by the sponsor in the project announcement, or costs that are clearly shown in the approved budget as AUCA's share. For example, a program description may indicate that sponsor funds must be matched at x% for award eligibility.
Voluntary cost sharing includes expenses that have been contributed by AUCA to the project in excess of the sponsor's requirements or those listed in the approved budget. For example, if Professor Kudabaev actually spent 50% of his time working on the project instead of the 20% that he pledged in the proposed budget, the excess 30% (50% minus 20%) is considered voluntary cost sharing.
Federal regulations regarding cost sharing are found in OMB Circular A-110, "Uniform Administrative Requirements for Grants and Agreements with Institutions of Higher Education, Hospitals, and Other Non-Profit Organizations" (A-110). Subpart C, Section .23 of A-110 states in part;
Subpart C, Section .23 also delineates specific rules for valuation and documentation for volunteer services, donated supplies, property, buildings, and equipment.
