(a) The contracting officer shall not execute a contract modification that causes or will cause an
increase in funds without having first obtained a certification of fund availability, except for
modifications to contracts that-
(1) Are conditioned on availability of funds (see 32.703-2); or
(2) Contain a limitation of cost or funds clause (see 32.704).
(b) The certification required by paragraph (a) of this section shall be based on the negotiated price,
except that modifications executed before agreement on price may be based on the best available
estimate of cost.
(c) In accordance with 10 U.S.C. 983, do not provide funds by contract or contract modification, or
make contract payments, to an institution of higher education that has a policy or practice of
hindering Senior Reserve Officer Training Corps units or military recruiting on campus as described
at 9.110. The prohibition in this paragraph (c) does not apply to acquisitions at or below the
simplified acquisition threshold or to acquisitions of commercial products, including commercially
available off-the-shelf items, and commercial services.
43.106 [Reserved]
43.107 Contract clause.
The contracting officer may insert a clause substantially the same as the clause at 52.243-7,
Notification of Changes, in solicitations and contracts. The clause is available for use primarily in
negotiated research and development or supply contracts for the acquisition of major weapon
systems or principal subsystems. If the contract amount is expected to be less than $1,000,000, the
clause shall not be used, unless the contracting officer anticipates that situations will arise that may
result in a contractor alleging that the Government has effected changes other than those identified
as such in writing and signed by the contracting officer.
Subpart 43.2 - Change Orders
43.201 General.
(a) Generally, Government contracts contain a changes clause that permits the contracting officer to
make unilateral changes, in designated areas, within the general scope of the contract. These are
accomplished by issuing written change orders on Standard Form 30, Amendment of
Solicitation/Modification of Contract (SF 30), unless otherwise provided (see 43.301).
(b) The contractor must continue performance of the contract as changed, except that in cost-
reimbursement or incrementally funded contracts the contractor is not obligated to continue
performance or incur costs beyond the limits established in the Limitation of Cost or Limitation of
Funds clause (see 32.706-2).
(c) The contracting officer may issue a change order by electronic means without a SF 30 under
unusual or urgent circumstances, provided that the message contains substantially the information
