48 CFR 1516.303-73: 1516.303-73 Types of cost-sharing.

(a) Cost-sharing may be accomplished in various forms or combinations. These include, but are not limited to: cash outlays, real property or interest therein, personal property or services, cost matching, or other in-kind contributions.

(b) In-kind contributions represent non-cash contributions provided by the performing contractor which would normally be a charge against the contract. While in-kind contributions are an acceptable method of cost-sharing, should the booked costs of property appear unrealistic, the fair market value of the property shall be determined pursuant to 1516.303-74 of this chapter.

(c) In-kind contributions may be in the form of personal property (equipment or supplies) or services which are directly beneficial, specifically identifiable and necessary for the performance of the contract. In-kind contributions must meet all of the following criteria before acceptance.

(1) Be verifiable from the contractor's books and records;

(2) Not be included as contributions under any other Federal contract;

(3) Be necessary to accomplish project objectives;

(4) Provide for types of charges that would otherwise be allowable under applicable Federal cost principles appropriate to the contractor's organization; and

(5) Not be paid for by the Federal Government under any contract, agreement or grant.
