48 CFR 37.106 - Funding and term of service contracts.
(a) When contracts for services are funded by annual appropriations, the term of contracts so funded shall not extend beyond the end of the fiscal year of the appropriation except when authorized by law (see paragraph (b) of this section for certain service contracts, 32.703-2 for contracts conditioned upon availability of funds, and 32.703-3 for contracts crossing fiscal years).
(b) The head of an executive agency, except NASA, may enter into a contract, exercise an option, or place an order under a contract for severable services for a period that begins in one fiscal year and ends in the next fiscal year if the period of the contract awarded, option exercised, or order placed does not exceed one year (10 U.S.C. 2410a and 41 U.S.C. 3902). Funds made available for a fiscal year may be obligated for the total amount of an action entered into under this authority.
(c) Agencies with statutory multiyear authority shall consider the use of this authority to encourage and promote economical business operations when acquiring services.
