Multiyear contract
Multiyear contract means a contract for the purchase of supplies or services for more than 1, but not more than 5, program years. A multiyear contract may provide that performance under the contract during the second and subsequent years of the contract is contingent upon the appropriation of funds, and (if it does so provide) may provide for a cancellation payment to be made to the contractor if appropriations are not made. The key distinguishing difference between multiyear contracts and multiple year contracts is that multiyear contracts, defined in the statutes cited at 17.101, buy more than 1 year's requirement (of a product or service) without establishing and having to exercise an option for each program year after the first.
